  1. Hi. I'm a Flash guy that's been dabbling in HTML5/Javascript stuff off and on for about a year now. Here's what I'm trying to accomplish: Eight circles of different colors animating in to form a ring (using a bezier curve) with the bottom circles overlapping the top ones (seen in circles.png) Once animated in to position, clicking on one of the circles will animate them until the clicked circle is at the bottom. The layers/zIndex will distribute correctly to match the original layout. I'm using TweenMax right now to animate the intro and it works pretty well. However, I'm using setTimeout to stop the animations so they stop when they get to the "correct" position to form the ring. This is a little finicky, as they will stop in slightly different positions each time. This leads to my first question: is there a better way stop the animations so the circles stop evenly along the ring? The other part of this is how I'm going about it. Eventually I'll want the animations to go back and forth simultaneously when you click a circle and i'm wondering: will this be done easily using functions of TweenMax like reverse or will TimelineMax be better for this situation? One last question... Here is some of my code: TweenMax.to( circleArr[0], .5, { css:{ zIndex:0, bezier:{ curviness:1.5, values:[ {left:100, top:100}, {left:75, top:75}, {left:100, top:50} ] } }, ease:Linear.easeInOut } ); I use the bezier line a few times and I'm wondering if I can simplify it by doing something like: var bez1 = BezierPlugin.bezierThrough([{left:100, top:100}, {left:75, top:75}, {left:100, top:50}], 1.5); TweenMax.to( circleArr[0], .5, { css:{ zIndex:0, bezier:bez1 }, ease:Linear.easeInOut } ); I'm submitting a zip file with my work so far. Let me know if you have any suggestions or questions about what I'm trying to do. Thanks! Test.zip
  2. Note: This page was created for GSAP version 2. We have since released GSAP 3 with many improvements. While it is backward compatible with most GSAP 2 features, some parts may need to be updated to work properly. Please see the GSAP 3 release notes for details. New DirectionalRotationPlugin Have you ever tweened rotation to a particular value but wished that you could control which direction it traveled (clockwise or counter-clockwise)? For example, if the current rotation is 170 and you tween to -170, normally that would travel counter-clockwise -340 degrees but what if you prefer rotating 20 degrees clockwise instead? Or maybe you just want it to go in the shortest direction to that new position (20 degrees in this case). This is all possible now with the DirectionalRotationPlugin. Previously, shortRotation was available in CSSPlugin, but there were three shortcomings (pardon the pun): It always went in the shortest direction - it wasn't possible to define a particular direction (clockwise or counter-clockwise). It required using a different property name ("shortRotation" or "shortRotationX" or "shortRotationY") instead of the regular property name ("rotation" or "rotationX" or "rotationY"). It only worked on DOM elements. What if you have a generic object or an EaselJS Shape (or whatever)? The new DirectionalRotationPlugin solves all of these issues. First of all, its functionality is baked into CSSPlugin, so you don't even need to load the DirectionalRotationPlugin if you're only animating DOM elements. The plugin is also included in TweenMax, so there's no need to load a separate plugin there either. Use the new syntax to get the desired behavior - add one of the following suffixes to the value: "_cw" for clockwise, "_ccw" for counter-clockwise, and "_short" to go whichever direction is shortest. Here are some examples: //tweens to the 270 position in a counter-clockwise direction (notice the value is in quotes) TweenMax.to(element, 1, {rotation:"270_ccw"}); //tweens to the -45 position in a clockwise direction TweenMax.to(element, 1, {rotation:"-45_cw"}); //tweens 1.5 radians more than the current rotationX value, and travels in the shortest direction TweenMax.to(element, 1, {rotationX:"+=1.5rad_short"}); If you're tweening a more generic object (anything that's not a DOM element), you can use the DirectionalRotationPlugin. If you pass in a simple value, it will assume you're attempting to tween the target's "rotation" property but you can tween ANY rotational properties of any name by passing in an object with the appropriate properties. Here are some examples: //start with a generic object with various rotation values var obj = {rotation:45, rotationX:0, rotationY:110}; //tweens rotation to 270 in a clockwise direction TweenLite.to(obj, 1, {directionalRotation:"270_cw"}); //tweens rotationX to -45 in a counter-clockwise direction and rotationY to 200 in a clockwise direction: TweenLite.to(obj, 1, {directionalRotation:{rotationX:"-45_ccw", rotationY:"200_cw"}}); As of 1.9.0, shortRotation is deprecated in favor of this new (more flexible and concise) syntax. New AttrPlugin This plugin allows you to tween any numeric attribute of a DOM element. For example, let's say your DOM element looks like this: <rect id="rect" fill="none" x="0" y="0" width="500" height="400"></rect> You could tween the "x", "y", "width", or "height" attributes using AttrPlugin like this: //tuck any attributes you want to tween into an attr:{} object TweenMax.to("#rect", 1, {attr:{x:100, y:50, width:100, height:100}, ease:Linear.easeNone}); You can tween an unlimited number of attributes simultaneously. Just use the associated property name inside the attr:{} object. The AttrPlugin is included inside the TweenMax JS file, so you don't need to load the plugin separately if you're using TweenMax. New TextPlugin This plugin allows you to tween the text content of a DOM element, replacing it one character at a time (or one word at a time if you set the delimiter to " " (a space) or you can even use a custom delimiter). So when the tween is finished, the DOM element's text has been completely replaced. This also means that if you rewind/restart the tween, the text will be reverted to what it was originally. Here is a simple example of replacing the text in yourElement: //replaces yourElement's text with "This is the new text" over the course of 2 seconds TweenMax.to(yourElement, 2, {text:"This is the new text", ease:Linear.easeNone}); If you'd like to use a different delimiter so that instead of replacing character-by-character, it gets replaced word-by-word, just pass an object with configuration properties like this: //replaces word-by-word because the delimiter is " " (a space) TweenMax.to(yourElement, 2, {text:{value:"This is the new text", delimiter:" "}, ease:Linear.easeNone}); Sometimes it's useful to have the new text differentiated visually from the old text, so TextPlugin allows you to assign a css class to the new and/or old content, like this: //wraps the old text in <span class="class1"></span> and the new text in a <span class="class2"></span> TweenLite.to(yourElement, 2, {text:{value:"This is the new text", newClass:"class2", oldClass:"class1"}, ease:Power2.easeIn}); As indicated, defining a newClass and/or oldClass will result in wrapping a <span> tag around the associated text. The TextPlugin is NOT included inside TweenMax, so you'll need to load it separately. Other updates and enhancements in 1.9.0: Added support for hsl() and hsla() colors in CSSPlugin and ColorPropsPlugin Implemented a new (more concise and clear) way to register plugins. Old plugins will still work fine, but most of the new ones in 1.9.0 use the new style of registering which won't work with old versions of TweenLite/TweenMax. Please just make sure all your files are updated. Fixed issue that caused className to be ignored by the autoCSS feature that creates the css:{} wrapper internally. Fixed issue that could cause em not to be translated to px accurately, causing a jump when the start and end units for the tween don't match (like px to em or visa-versa) Fixed backfaceVisibility so that it is properly prefixed when necessary Now setting "float" on a DOM element will work across browsers including Firefox and IE. Worked around issue that caused x/y/z transforms not to work properly if they exceeded 21,474 (or -21,474). Fixed issue that caused values not to be interpreted correctly if a negative number had a relative prefix, like "+=-50px" or "-=-50px" Fixed issue in EaselPlugin that prevented ColorMatrixFilter tweens from working correctly when the starting matrix wasn't an identity matrix Now fromTo() and staggerFromTo() methods have immediateRender set to true by default, just like from() and staggerFrom() always did. This seems like the preferred behavior for most developers, but you can certainly set immediateRender:false on any tween if you prefer that behavior. Now fromTo() and staggerFromTo() tweens that have immediateRender:false will record their pre-tween values (before even implementing the "from" part of the tween) so that if their parent timeline rewinds past the beginning of the tween, it restores values to their originals.

  3. Hi I'm new to Tweenlite, have a query that may be very simple. I have a tween thats repeating an object being rotated 360degrees, I want to update the tween so it eases out to a new degree requirement e.g. from... thisTween = new TweenMax(rec, 4, {rotation:"360", ease:Linear.easeNone, repeat:-1 }); to {rotation:"25", ease:Linear.easeNone, repeat:0 }); so it basically eases the objects rotation, stopping at 25 degrees. Spent the last hour trying to solve this, nothing so far. Any help greatly appreciated. Many thanks.
  4. Big thank you to everyone that makes this forum such a huge asset. I'm having an issue with a Kiosk I'm working on. Basically i've built it with each "slide" on its own flash timeline frame. For each flash timeline frame I have a GS timelineMax to make everything awesome. My issue is that when jumping to the next flash frame I get a momentary "flash" or blink of the content that is set to animate .from. it quickly goes away but is really unsightly. here's an excerpt. any help would be greatly appreciated. var timeline1:TimelineLite = new TimelineMax({ onComplete:goToTwo}); timeline1.append( TweenMax.from(FR1.MFPS, 2, {autoAlpha:0, rotationX:90, transformOrigin:"left top", ease:Elastic.easeOut, delay: 1})); timeline1.append( TweenMax.from(FR1.p1, .5, {autoAlpha:0, rotationY:90, transformOrigin:"left top", ease:Quint.easeIn, delay: .5})); timeline1.append( TweenMax.from(FR1.Ba, 2, {autoAlpha:0, rotationX:90, transformOrigin:"left top", ease:Elastic.easeOut, delay: -.05})); timeline1.append( TweenMax.from(FR1.p2, .5, {autoAlpha:0, rotationY:90, transformOrigin:"left top", ease:Quint.easeIn, delay: .5})); timeline1.append( TweenMax.from(FR1.ser, 2, {autoAlpha:0, rotationX:90, transformOrigin:"left top", ease:Elastic.easeOut, delay: -.05})); timeline1.append( TweenMax.from(FR1.equals, 1,{scrollRect:{x:0, y:0, width:0, height:140}, ease:Expo.easeInOut, delay: 0 })); function goToTwo(){ this.gotoAndStop(2); } stop();
  5. Hi i want to achieve a scrolling parallax background, with layers in front using greensock Tween Max is there a starting script i can use? Or can anyone help me with best way to do this. regards WL
  6. Hi, Can someone help me with this? I want it so when you roll over #box the tooltip (or ball in this case) appears and follows the mouse. When you roll out of #box the tooltip will fade away. This is where I am so far: http://codepen.io/hrk/pen/IguFo Any ideas on how to do this? Thanks
  7. I've been having an issue using TweenMax and setting the css properties of an element. It seems to be automatically picking out a z-index and applying it to the style of the element. I'm assuming this is something that was added as a quick fix for performance or css3 animation flickering as backface-visibility is also added without me requesting it (which is a whole different issue and really bogs down performance on iOS Safari). The code is: TweenMax.set(element, {css:{y:0}}); This ends up being: <div class="header" style="z-index: 0; -webkit-backface-visibility: hidden; -webkit-transform: translate(0px, 0px); ">...</div> The problem is the z-index on the style attribute is overriding the z-index i have applied in my stylesheet. And as it sets the value to 0, my element just disappears. I can manually set the z-index in the tween and fix that issue but i shouldn't have to worry about updating that value anywhere other than my css. Is there something that I'm applying improperly? Maybe another parameter that will remove this default behavior (tried autoRound: false but didn't work)? If this is the intended behavior might i suggest getting the element's z-index and applying that value to the style attribute so to not override it to 0. Thank you for this awesome platform. I've been using greensock for such a long time and so glad it made it to JS.
  8. Hi, I am new to Tweenmax and tweenlite. I hv heard that its lighter and faster. So, I thought I should use them in my project where I am currently using fl.tranistions I am developing my project in flashdevelop. But before using tweenmax in my main file I tried it on a small swf which I will import later on my main swf. When I was using fl transition package I had to import three classes import fl.transition.tween import fl.transition.easings*; import fl.transition.tweenEvent; and the generated swf file size was 6kb Later when I replaced fl transition with just one line of code import com.greensock.TweenMax and then the generated swf file became 38kb But the loading time for both files is almost same fl.transtion loads in 9sec and tweenmax loades in 11 sec. AstionScript 3. I am using gprs connection (200kbps) tweenmax fl.transition test.zip
  9. Hi, I'm new to TweenMax and was trying to achieve the following: I have a movieclip that move from left to right. What I want is that during the animation, to have a blur effect that kind of "fade in" and "fade out" on the beginning and end of the animation. Right now I'm able to blur my mc but I have problem with the "fade" parts. TweenMax.to(row_1, 8, { x:String(newX), blurFilter:{ blurX:40, remove:true } }); Can someone help me figuring out how to fade the blur effect with a sample or a tutorial. Thanks alot
  10. Note: This page was created for GSAP version 2. We have since released GSAP 3 with many improvements. While it is backward compatible with most GSAP 2 features, some parts may need to be updated to work properly. Please see the GSAP 3 release notes for details. Update: don't miss our guest post on css-tricks.com, Myth Busting: CSS Animations vs. JavaScript which provides some additional data, visual examples, and a speed test focused on this topic. Ever since CSS3 "transitions" and "animations" were introduced, they have been widely lauded as the future of animation on the web. It often seems like all the "cool kids" are talking about them. Should you jump on the bandwagon? Is JavaScript animation headed for extinction? How does the new GreenSock Animation Platform (GSAP) fare when it steps into the ring and faces off against the hyped-up tag-team of CSS3 transitions & animations? Does GSAP have the chops to hold its own? Let's find out. Ready...FIGHT! Performance One of the most common arguments in favor of CSS3 animations has been that they're hardware accelerated, thus outperform any JavaScript-based equivalent. The theory is that if you define your transitions/animations directly in css, the browser can worry about all the calculations behind the scenes and tap into hardware and native code to execute them. Sounds awesome. Unfortunately it's not quite that clean. Only certain properties are hardware-accelerated (like 3D transforms and opacity - mostly ones that don't affect document flow) and different browsers handle things differently. Plus every comparison we saw on the web pitted CSS3 transitions against jQuery, but GSAP is up to 20 times faster than jQuery. In our real-world tests, we saw drastic differences in performance among the various browsers and when tested head-to-head against GSAP, CSS3 animations were usually slower! Weird. As expected, however, 3D transforms were indeed faster under heavy stress although in most situations you'd never notice a difference. GSAP is extremely optimized. UPDATE (2015-01-05): There are some interesting (and surprising) performance implications of using CSS animations that aren't widely known. Here's a screencast that shows how Dev Tools doesn't report the overhead involved with CSS animations, some synchronization problems, and how they can drag down the main thread performance more than JS. To see a simple comparison for yourself, select the "Zepto" engine in the speed comparison because it uses CSS3 transitions for its animations, and then compare it to GSAP. Beware that the fps (frames per second) counter in the lower right corner isn't always accurate in some browsers (like recent versions of Safari) when using CSS3 transitions because requestAnimationFrame events [incorrectly] get dispatched even when the screen is clearly not being updated. So the animation may actually be running at a very jerky 10fps, yet 50+ requestAnimationFrame cycles are being triggered by the browser! This exposes another flaw in CSS3 transitions - there's no way to know when updates truly occur. There's only a "complete" event fired at the end of the transition/animation. If anyone knows how to get a more accurate fps counter in Safari while using CSS3 transitions, please let us know. Another performance issue to note in the speed comparison is the clumping that occurs with many engines (including Zepto) under heavy stress, where the stars begin pulsing out in rings instead of a nicely dispersed field. Even though GSAP was faster than CSS3 transitions in the majority of our real-world tests, it's still true that 3D transforms and opacity tweens are faster with CSS3 transitions and it's possible that browsers will be able to further tap into hardware acceleration in the future, so we'll call this round a tie. Feel free to build your own tests to see how things compare in your workflow. Performance winner: TIE Controls This is one of the major weak spots for CSS transitions (its "glass jaw" of sorts). Let's say you invest the time in writing a bunch of css for a whiz-bang animation and then you need to control the whole thing - good luck with that. It is virtually impossible. GSAP's object oriented architecture allows you to pause, resume, reverse, restart, or seek to any spot in any tween. Even adjust timeScale on the fly for slow motion or fastforward effects. Place tweens in a timeline with precise scheduling (including overlaps or gaps) and then control the whole thing just like it's a single tween. All of the easing and effects remain perfectly intact as you reverse, adjust timeScale, etc. (with CSS transitions, easing flip-flops upon reverse). You can even kill individual portions of a tween anytime (like if a tween is controlling both "top" and "left" properties, you can kill "left" while "top" continues). Put labels in a timeline to mark important spots and seek() to them anytime. Imagine trying to build the example below using CSS transitions. It would be virtually impossible. With GSAP, it's easy. In fact, all of the animation is done with 2 lines of code. Drag the scrubber, click the buttons below, and see how easy it is to control the sequenced animation. Controls winner: GSAP Tweenable Properties Both competitors can animate transforms (2D and 3D), colors, borderRadius, boxShadow, and pretty much every important property, but there's one key shortcoming of CSS - you cannot animate individual transforms distinctly! For example, try rotating an object and then halfway through that animation, start scaling it with a different ease and finish at a different time. Since all transforms (scaleX, scaleY, rotation, rotationX, rotationY, skewX, skewY, x, y, and z) are all mashed into one "transform" property, it's virtually impossible to handle them distinctly. GSAP not only works around this limitation, but it also allows you to do advanced things like animate along Bezier paths or do momentum-based motion (with ThrowPropsPlugin) or relative tweens or animate the scroll position or do directional rotation or physics-based motion, etc. Plus GSAP can animate any numeric property of any object, not just DOM elements. Do you really want to use one toolset (CSS) for animating DOM elements and then have to switch to a completely different toolset and syntax when you do canvas-based animation? GSAP handles both consistently. CSS transitions and animations just can't compete here. Tweenable properties winner: GSAP Workflow When you're creating fun and interesting animations, workflow is critical. You need to be able to quickly build sequences, stagger start times, overlap tweens, experiment with eases, leverage various callbacks and labels, and create concise code. It would be great to modularize your code by creating functions that each spit back an animation object (tween or timeline) which can be inserted into another timeline at a precise time. You need a flexible, powerful system that lets you experiment without wasting hours. GSAP wipes the floor with CSS transitions in this round. Anyone who has attempted an ambitious project with CSS3 transitions/animations will attest to the fact that they tend to get very cumbersome and verbose. Experimenting with timing and fine-tuning details can get extremely tedious especially when dealing with all the browser prefixes. GSAP CSS3 transitions = supported = unsupported Flexible object-oriented architecture that allows animations to be nested inside other animations as deeply as you want Supported Unsupported Concise code that doesn't require vendor prefixes Supported Unsupported Create sequences (even with overlapping animations) that auto-adjust as you insert/remove/change intermediate pieces of animation (makes experimenting MUCH easier) Supported Unsupported Accommodate virtually any ease including Bounce, Elastic, SlowMo, RoughEase, SteppedEase, etc. Supported Unsupported Animate things into place (backwards) with convenience methods like from() and staggerFrom() Supported Unsupported Callbacks for when an animation starts, updates, completes, repeats, and finishes reversing, plus optionally pass any number of parameters to those callbacks Supported Unsupported Place labels at specific times in a sequence so that you can seek() there (and/or insert animations there) Supported Unsupported Animate any numeric property of any JavaScript object, not just DOM elements (great for canvas-based animation). Supported Unsupported Workflow winner: GSAP Compatibility CSS transitions simply don't work in older browsers, even Internet Explorer 9. GSAP works in all browsers (although some particular features may be disabled, like 3D transforms in IE8). Once again, this round was no contest. GSAP can even do 2D transforms like rotation, scaleX, scaleY, x, y, skewX, and skewY all the way back to IE6 including transformOrigin functionality! Plus it works around scores of other browser issues so that you can focus on the important stuff. Safari's 3D transformOrigin bug? No problem. Firefox's flashing 3D elements bug? No worries. Inconsistency in IE's backgroundPosition values? GSAP has you covered. Vendor prefixes? Nah, GSAP adds 'em for you when necessary. Compatibility winner: GSAP Popularity CSS3 transitions have been talked about (and used) for years all over the web whereas GSAP is relatively new. It can't match CSS3 transitions' popularity. As clients start pushing for more aggressive animations and HTML5 games proliferate and operating systems become very JavaScript-friendly, the balance may very well shift quickly. For now, though, this round goes squarely to CSS transitions. Popularity winner: CSS3 transitions Conflict management What happens if a particular set of properties (like "left" and "top") are animating and then you need to redirect one of those to a different value (like "left" to 100px instead of 300px) using a different ease and duration? With CSS transitions, it's a very complex process. With GSAP, it's simple and automatic. In fact, there are several overwrite modes you can choose from. Conflict management winner: GSAP Support There are numerous places on the web where you can ask the community your CSS transitions-related questions, but GSAP has dedicated support forums where there's rarely a question that remains unanswered for more than 24 hours. GreenSock's forums are manned by paid staff (including the author of the platform), so you're quite likely to get solid answers there. Add to that the fact that GreenSock has a track record of being much more agile in terms of squashing bugs and releasing updates than browsers do for CSS3 transitions, so GSAP gets the upper hand here. Support winner: GSAP Expandability GSAP employs a plugin architecture, making it relatively easy to add features and custom animation properties but CSS transitions have no such equivalent. You're stuck with what the browsers decide to offer. In addition to CSSPlugin, GSAP already has plugins like ScrollToPlugin for scrolling to specific window or div scroll positions, BezierPlugin for animating along Bezier curves, ThrowPropsPlugin for momentum-based motion, and RaphaelPlugin, EaselPlugin, and KineticPlugin for those libraries (Raphael, EaselJS, and KineticJS). Plus there are physics-based plugins like Phyics2DPlugin and PhysicsPropsPlugin as well as a fun ScrambleTextPlugin for Club GreenSock members. More plugins are on their way, and you can create your own too. Expandability winner: GSAP Learning resources Again, the popularity of CSS3 transitions trumps anything GSAP could throw at it right now. There are lots of tutorials, videos, and articles about CSS3 transitions whereas GSAP is new to the game. GreenSock is being aggressive about putting together solid resources (like the Jump Start tour) and the community is crankin' out some great articles and videos too, but CSS3 transitions score the win in this round. Learning resources winner: CSS3 TRANSITIONS Price & license Both CSS3 transitions and GSAP are completely free for almost every type of usage. GSAP allows you to edit the raw source code to fix bugs (if that's something you need to do), but there's no way to edit the source code that drives CSS3 transitions. Then again, there's no special license required to use them either. If you plan to use GSAP in a product/app/site/game for which a fee is collected from multiple customers, you need the commercial license that comes with "Business Green" Club GreenSock memberships (one-off commercial projects don't require the special license). It's actually a more business-friendly license in many ways than a typical open source license that offers no warranties or backing of any kind or imposes code sharing or credit requirements. GreenSock's licensing model provides a small funding mechanism that benefits the entire user base because it empowers continued innovation and support, keeping it free for the vast majority of users. See the licensing page for details. Although there are some clear benefits of GreenSock's model, we'll give this round to CSS3 transitions because using them is technically "free" in more scenarios than GSAP. Price & license winner: CSS3 TRANSITIONS File size This is a tricky round indeed because GSAP requires inclusion of at least 1 JavaScript file whereas CSS3 transitions leverage native code in the browser, but the code you'd have to write to accomplish the same thing in CSS3 animations or transitions is often far more verbose, offsetting the kb savings. For example, let's take a relatively simple sequenced animation (see codepen or jsfiddle? GSAP code: var tl = new TimelineLite(); tl.staggerFrom('.box', 0.5, {opacity:0, scale:0, rotation:-180}, 0.3) .staggerTo('.box', 0.3, {scale:0.8}, 0.3, 0.7); This type of thing is impossible with CSS3 transitions, but it can be done with CSS3 animations as long as we give each element its own class name or ID. Let's take a look at the CSS code (see codepen or jsfiddle? Equivalent CSS3 Animation: .animated { -webkit-animation-fill-mode: both; -moz-animation-fill-mode: both; animation-fill-mode: both; -webkit-animation-duration: 1s; -moz-animation-duration: 1s; animation-duration: 1s; } @-webkit-keyframes introAnimation { 0% { -webkit-transform: scale(0) rotate(-180deg) ; opacity: 0; } 50% { -webkit-transform: scale(1) rotate(0deg) ; opacity: 1; } 70% { -webkit-transform: scale(1) rotate(0deg); } 100% { -webkit-transform: scale(0.8) rotate(0deg); } } @-moz-keyframes introAnimation { 0% { -moz-transform: scale(0) rotate(-180deg); opacity: 0; } 50% { -moz-transform: scale(1) rotate(0deg); opacity: 1; } 70%{ -moz-transform: scale(1) rotate(0deg); } 100% { -moz-transform: scale(0.8) rotate(0deg); } } @keyframes introAnimation { 00% { transform: scale(0) rotate(-180deg); opacity: 0; } 50% { transform: scale(1) rotate(0deg); opacity: 1; } 70%{ transform: scale(1) rotate(0deg); } 100% { transform: scale(0.8) rotate(0deg); } } .introAnimation { -webkit-backface-visibility: visible !important; -webkit-animation-name: introAnimation; -moz-backface-visibility: visible !important; -moz-animation-name: introAnimation; backface-visibility: visible !important; animation-name: introAnimation; } .two { -webkit-animation-delay: 0.3s; -moz-animation-delay: 0.3s; animation-delay: 0.3s; } .three { -webkit-animation-delay: 0.6s; -moz-animation-delay: 0.6s; animation-delay: 0.6s; } .four { -webkit-animation-delay: 0.9s; -moz-animation-delay: 0.9s; animation-delay: 0.9s; } .five { -webkit-animation-delay: 1.2s; -moz-animation-delay: 1.2s; animation-delay: 1.2s; } .six { -webkit-animation-delay: 1.5s; -moz-animation-delay: 1.5s; animation-delay: 1.5s; } .seven { -webkit-animation-delay: 1.8s; -moz-animation-delay: 1.8s; animation-delay: 1.8s; } .eight { -webkit-animation-delay: 2.1s; -moz-animation-delay: 2.1s; animation-delay: 2.1s; } .nine { -webkit-animation-delay: 2.4s; -moz-animation-delay: 2.4s; animation-delay: 2.4s; } As you can see, the CSS3 code is more than 10 times longer! And what if you want to have the entire sequence repeat 3 times? Good luck with that in CSS - you can set an animation-iteration-count but it only applies to each individual element, so it doesn't give us the effect we're after. And what if you want to experiment with the easing or offsets/delays or rotational values? It is quite cumbersome to say the least, even if you use sass or something like that. With GSAP, it's simple. If you only need very simple animations/transitions, CSS3 would deliver smaller file sizes, but once you start getting more aggressive and expressive with your animations, the scales shift quickly and GSAP becomes more economical. The other thing to keep in mind is that GSAP's JS file(s) are typically cached by the browser, so the savings page-to-page is much larger since the code you write on each page is far more concise. In other words, think of how much js/css the browser must actually request from the server over the course of your users' multi-page visit to your site. File size winner: TIE Flexibility Let's face it: basic tweening is pretty straightforward for any system, but it's really the details and advanced features that make a robust platform shine. GSAP crushes CSS3 transitions and animations when it comes to delivering a refined, professional-grade tool set that's truly flexible. Here are just a few of the conveniences baked into GSAP: Tween any numeric property of any object. Optionally round values to the nearest integer to make sure they're always landing on whole pixels/values. Animate along Bezier curves, even rotating along with the path or plotting a smoothly curved Bezier through a set of points you provide (including 3D!). GSAP's Bezier system is super flexible in that it's not just for x/y/z coordinates - it can handle ANY set of properties. Plus it will automatically adjust the movement so that it's correctly proportioned the entire way, avoiding a common problem that plagues Bezier animation systems. You can define Bezier data as Cubic or Quadratic or raw anchor points. Animate any color property of any JavaScript object (not just DOM elements). Define colors in any of the common formats like #F00 or #FF0000 or rgb(255,0,0) or rgba(255,0,0,1) or hsl(30, 50%, 80%) or hsla(30, 50%, 80%, 0.5) or "red". Set a custom fps (frames per second) for the entire engine (the default is 60fps). All tweens are perfectly synchronized (unlike many other tweening engines). Use the modern requestAnimationFrame API to drive refreshes or a standard setTimeout (the default is requestAnimationFrame with a fallback to setTimeout) Tons of easing options including proprietary SlowMo, RoughEase, and SteppedEase along with all the industry standards Animate css style sheet rules themselves with CSSRulePlugin Animate the rotation of an object in a specific direction (clockwise, counter-clockwise, or whichever is shortest) by appending "_cw", "_ccw", and "_short" to the value. You can tween getter/setter methods, not just properties. For example, myObject.getProp() and myObject.setProp() can be tweened like TweenLite.to(myObject, 1, {setProp:10}); and it will automatically recognize that it's a method and call getProp() to get the current value when the tween starts. Same for jQuery-style getters/setters that use a shared method like myObject.prop(). You can even tween another tween or timeline! For example, TweenLite.to(otherTween, 1, {timeScale:0.5}) would animate otherTween.timeScale to 0.5 over the course of 1 second. You can even scrub the virtual playhead of one tween/timeine with another tween by animating its "time". Flexibility winner: GSAP Conclusion Despite the hype surrounding CSS3 transitions and animations, they just aren't well-suited for professional-grade animation tasks. They did manage to win a few rounds in this match but ultimately GSAP man-handled them, sending them running from the ring like scared sissies. Of course we're slightly biased, but check out the facts for yourself. Kick the tires. Audition GSAP on your next project. See how it feels once you get past the initial learning curve. If you only need simple fades or very basic animation in modern browsers, CSS3 transitions are probably just fine. However, what happens when your client wants to do something more expressive? What if browser compatibility becomes an issue? Why not build on a solid foundation to begin with so that you don't find yourself having to rewrite all your animation code? If you want professional-grade scripted animation, look no further. To get started fast, check out our Jump Start tour. Recommended reading: Main GSAP JS page Why GSAP? A practical guide for developers Jump Start: GSAP JS jQuery vs GSAP: cage match 3D Transforms & More CSS3 Goodies Arrive in GSAP JS Speed comparison Explanation of CSS3 transitions, transforms and animations P.S. A rant about where animation logic belongs: We can't put this post to bed without mentioning a beef we've got with the whole concept of putting all your animation logic in css. Ever since the <blink> tag, there has been this tendency for browser vendors to offer developers these nifty "conveniences" that end up encouraging them to mix markup and/or style rules with behavioral logic. Is that really a good idea? One of the wonderful things about the modern web is that we've got this lovely separation between markup, presentation/styling, and behavioral logic (at least that's the goal). Should we be blurring the line like this? Isn't JavaScript the logic layer that should be handling state changes, application logic, reaction to user interaction (which often includes animation), etc.? Some may claim "But putting animation in css is great because that way if the user has JavaScript disabled, the animations still work!" Do you really think users of the modern web can turn off JavaScript and expect to browse the web with great results? Is that who you're targeting for a rich experience? And if they turned off JavaScript, might they have done so specifically to avoid annoying animations? Is it really helping to shift animation logic into css where they can't turn it off? In the web of yesteryear, animations were quite simplistic; fade this, slide that. Done. Anything more aggressive was relegated to a plugin like Flash which afforded incredible richness and complexity in terms of animation. But today, clients want that sort of expressiveness directly in the browser. It needs to work on mobile devices. It's no longer about simple fade-ins or sliding an image across the screen. CSS3 transitions fit the old mentality well, but not the new one. CSS3 animations technically provide more flexibility but they fall miserably short and they still force behavioral logic into the style layer. And to use them effectively, we still need JavaScript to at least swap classes and trigger things. From a development and debugging standpoint, when I apply a class to an element how would I know if that will trigger an animation or transition or neither? Should I have to keep bouncing back and forth between css and JS to manage behavioral logic related to animations? Maybe we're just ill-informed and there are some fantastic reasons for putting behavioral logic like animation into the css layer, but one thing seems pretty clear: the current way that developers have to build all but the simplest css animation leaves a LOT to be desired. The API is terribly limiting and clunky. Let's move the web forward. Let's make animation fun and flexible. Let's keep behavioral logic and style rules distinct. Let's leverage the incredible flexibility of JavaScript. If we've misrepresented anything here or if you want to weigh in with your opinion about where behavioral logic like animation belongs, feel free to post your comment below. If you're someone who has attempted an aggressive animation task with CSS3 transitions/animations as well as GSAP, we'd love to hear how you felt they compared.
  11. I'm having an issue with Animating alpha PNGs in TweenMax JS in IE8, there is a lot of distortion during the animation but after it is complete the PNGs return to a normal state. I know IE8 inherently has issues with PNGs but is there a work around for this in TweenMax?
  12. I'm new to JS/CSS (coming from AS3) -- I wonder if someone could help me figure out the following: I'd like to have tabs at the bottom of a page which, when rolled over (or clicked) slide up. The tabs will contain images of 45px height. I'd like, say, the extended tab to be something like 100px in height. I gather this has something to do with overflow, hidden, auto, etc -- I've seen solutions using jQuery slide, but I'm not sure how to do it with Greensock -- that is, I am well-versed in the GS engines, but putting it all together (CSS, DIVs, overflows, etc) is throwing me. Any help much appreciated!
  13. As an erstwhile AS3 developer moving over to some JS, could someone clarify this for me? I was trying to move a div on screen and then (when invisible) set it back to where it started. Something like this (swapOut is a JQuery object): TweenMax.to(swapOut,0.4,{css:{x,opacity:0},onComplete:this.finishSwapImages,onCompleteParams:[swapOut,swapOut.css('x')]}); But I could never get it set back where I wanted? See the obvious error: I'm using 'x' instead of 'left'. When I inspected in Firebug I saw that my div's css had a transform-matrix set on it. When I went back and did this, all worked fine TweenMax.to(swapOut,0.4,{css:{left,opacity:0},onComplete:this.finishSwapImages,onCompleteParams:[swapOut,swapOut.css('left')]}); My question is: what's TweenMax doing for me with respect to x? Is this a proper CSS property? — or is TweenMax lending a helpful hand for us AS3 people and moving stuff in a tricky way when we (mistakenly) say 'x'? If so, what else is like this in the JS version? ("y" -> "top", etc?)
  14. I'm trying to figure out the best practice for an image swap. I'm coming from AS, new to JS, but I have a basic idea of what to do -- and nothing seems to work. I'm trying to use the old 'make a UL inline for a horizontal menu' trick -- I ran through all of these options but couldn't get any to work 1) loaded both images into the <li> with different z-indexes, thinking that I'd TweenMax the top image to 0 opacity on rollover -- even with float:left they sat next to each other not on top of each other. 2) I set the "over" image as the background with CSS and put the "out" image in the <li> and then tweened the "out" image to 0 opacity on rollover. Somehow this seemed to collapse the box -- the background image wasn't displayed when the front was invisible -- this seemed to be a result of the 'display:inline' The easiest thing is to simply swap 'src' on rollover -- but I'm looking for a gradual transition. Any suggestions? I know it's hard to talk about what I'm doing/not doing without my code, but in lieu of that, if someone could provide a sample, or a link, that would be helpful. Thanks!
  15. Adding autorotate to my bezier curve stops it from working in Safari (5.1.7) It just pins around in one spot and doesn't follow the curve. Removing the auto rotate parameter fixes it. Anyone any ideas?! Can't find anyone with this problem and not sure what to do about it, I really need it to auto rotate with the curve. Works in all other browsers! var anim = new TimelineMax(); anim.append(TweenMax.to($('#anim'), 2, {css:{bezier: {values: [{left:'3578px', top:'2417px'},{left:'3431px', top:'2362px'},{left:'3190px', top:'2252px'}], autoRotate: true}}, ease: Linear.easeNone}));
  16. Note: This page was created for GSAP version 2. We have since released GSAP 3 with many improvements. While it is backward compatible with most GSAP 2 features, some parts may need to be updated to work properly. Please see the GSAP 3 release notes for details. GSAP's CSSPlugin is now super-charged to handle some slick new CSS3 properties like 3D transforms, boxShadow, textShadow, borderRadius and clip. Plus you don't need to worry about a litany of vendor prefixes. GSAP makes it easy to create next-generation effects today. [Note: the animation below is NOT a video - it's regular DOM elements being animated with GSAP. And yes, the scrubber works!] 3D transforms textShadow boxShadow borderRadius clip JS -moz- -o- -webkit- -ms- -no-more- play These features work in virtually all modern-day browsers (see caniuse.com for details about browser support for each feature). Generally if the browser supports the css property (browser-prefixed or not), you can animate it with GSAP's CSSPlugin. In fact, GSAP even works around several browser bugs and glitches to deliver a whole new level of consistency to your animations. It can't work miracles or, for example, permit fancy 3D transforms in IE8, but it does a bunch of work under the hood to empower these features as consistently as possible. 3D Transforms Browser support: GOOD (Chrome 12, Safari 4, Firefox 10, IE 10, iOS 3.2, Android 3.0) see details GSAP makes it a breeze to create amazing 3D effects. In addition to all the standard 2D transform properties like rotation, scaleX, scaleY, x, and y, you can also tween 3D properties like rotationX, rotationY, rotationZ, z, perspective and transformPerspective. You can even create multiple tweens that animate each property independently in a staggered fashion and/or with different eases (something virtually impossible to do with CSS3 transitions). In order to get the most out of these 3D properties, it's important to understand how perspective and transformPerspective work. They both affect the amount of distortion applied in 3D space. transformPerspective affects only the element that is being animated, making it look as though it has its own distinct vanishing point in its own 3D space. You can choose to give each element a transformPerspective specifically or use CSSPlugin.defaultTransformPerspective to set a default that will be used for all animated elements that don't have one specifically defined. transformPerspective no transformPerspective No visual distortion at all. Impossible to distinguish vanishing point or depth. DOM elements by default have no transformPerspective. transformPerspective:200 The lower the transformPerspective, the more extreme the distortion. transformPerspective:600 With a higher value the 3D effect is less pronounced. play perspective should be applied to the parent of the element(s) being animated - an element's perspective affects all of its children, allowing them to share a common vanishing point. Typically this is the best way to apply realistic perspective to multiple elements (instead of using transformPerspective on each child element). Practically speaking, you'd almost never use BOTH transformPerspective AND perspective. transformPerspective Vs perspective transformPerspective is applied to each box causing each box to have its own vanishing point A single perspective is applied to the parent div of all the boxes causing each box to share the same vanishing point play transformOrigin can add some really interesting effects - think of it like a pivot point around which your transforms happen. By default, it is in the center of the element ("50% 50%"). transformOrigin is a space-delimited string of values in the following order [x-axis y-axis z-axis] (the z-axis value is optional). You can define the values using the keywords "top", "left", "right", or "bottom" or use percentages (bottom right corner would be "100% 100%") or pixels. transformOrigin The negative z-index (-200) set in the transformOrigin properties of the second animation changes the effect drastically. TweenMax.to(box1, 3, {rotationY:360, transformOrigin:"left top"}) TweenMax.to(box2, 3, {rotationY:360, transformOrigin:"left 50% -200"}) play Caveats: Performance can vary greatly between the browsers. Generally Webkit browsers like Chrome and Safari do best by far, and Firefox lags behind but updates are getting pushed out pretty aggressively by everyone so things can change fast. In some browsers, you may notice a slight shift of pixels when an element starts/ends a 3D animation. This has nothing to do with GSAP - it's the browser jumping into 3D mode and working with the GPU. The only known workaround is to make sure you apply some sort of 3D transform from the beginning which you could do in your css like "transform:translateZ(0.1px);" (plus the obligatory vendor-prefixed variations). Font antialiasing can appear to change when there's a 3D element on screen. Again, this is a browser issue and has nothing to do with GSAP. In Webkit browsers, you can [mostly] resolve this by setting -webkit-font-smoothing:antialiased in your css. If a browser doesn't support 3D transforms, they will simply be ignored (no errors are generated). In some versions of Firefox, elements with BOTH a boxShadow AND 3D transforms applied don't always render correctly (again, it's a browser issue). We're not aware of a workaround but we expect Firefox to fix the bug in a future release. IE10 supports 3D transforms, but it does not support transformStyle of "preserve-3d" (see Microsoft's site for details). textShadow Browser support: GOOD (Chrome 22, Safari 5.1, Firefox 15, IE 10, Opera 12.1, iOS 3.2, Android 2.1) see details textShadow takes a space-delimited string consisting of up to 4 values (just like standard css) h-shadow: The horizontal offset of the shadow. Negative numbers are allowed. v-shadow: The vertical offset of the shadow. Negative numbers are allowed. blur: Blur distance (optional). color: Shadow color (optional). Use any color format: #ff000, #f00, red, rgb(255, 0, 0) or rgba(255, 0, 0, 0.5) for control over the opacity of the shadow. TweenMax.to(element, 0.2, { textShadow:"10px 10px 10px rgba(255, 255, 255, 0.5)" }); Move your cursor over each word to see a different textShadow effect. GLOW BLACKOUT GHOST TweenMax.to(glow, 0.2, { textShadow:"2px 2px 15px rgba(145, 233, 0, 1)", color:"#91ff00" }); TweenMax.to(blackout, 0.2, { textShadow:"1px 1px 1px rgba(255, 255, 255, 0.5)", color:"#000" }); TweenMax.to(ghost, 0.2, { textShadow:"0px 0px 15px white", color:"none" // IE10 unfortunately hides the shadow too }); boxShadow Browser support: VERY GOOD (Chrome 22, Safari 5.1, Firefox 15, IE 9, Opera 12.1, iOS 3.2, Android 2.1) see details A nice boxShadow animation can visually lift an element off the screen or add an attention-grabbing glow effect. Repeat and yoyo a TweenMax to give it a pulsing glow easily. boxShadow takes a space-delimited string consisting of up to 5 values in standard css form: h-shadow: The horizontal offset of the shadow. Negative numbers are allowed. v-shadow: The vertical offset of the shadow. Negative numbers are allowed. blur: Blur distance (optional). spread: Expansion amount of the shadow beyond the size of the element (optional). color: Shadow color (optional). Use any standard color format like #ff000, #f00, red, or rgb(255, 0, 0). TweenMax.to(element, 0.5, { boxShadow:"0px 0px 10px 10px rgb(0, 204, 0)" }); Move your cursor over the buttons to see a variety of boxShadow effects. sharp shadow blur shadow black spread orange glow green pulse white blur TweenMax.to(sharpShadow, duration, { boxShadow: "10px 10px", }); TweenMax.to(blurShadow, .3, { boxShadow: "10px 10px 10px", backgroundColor:"black" }); TweenMax.to(blackSpread, .3, { boxShadow: "0px 0px 10px 6px black", backgroundColor:"black" }); TweenMax.to(orangeGlow, .3, { boxShadow: "0px 0px 10px 4px #f60", backgroundColor:"#f60", borderColor:"#f60" }); TweenMax.fromTo(greenPulse, 0.7, { boxShadow: "0px 0px 0px 0px rgba(0,255,0,0.3)" }, { boxShadow: "0px 0px 20px 10px rgba(0,255,0,0.7)", repeat: -1, yoyo: true, ease: Linear.easeNone }); TweenMax.to(bsBox5, 0.5, {backgroundColor:"black"}); TweenMax.to(whiteBlur, .3, { boxShadow: "0px 0px 24px 6px white", backgroundColor:"white", color:"#999" }); borderRadius Browser support: VERY GOOD (Chrome 22, Safari 5.1, Firefox 15, IE 9, Opera 12.1, iOS 3.2, Android 2.1) see details CSSPlugin deftly handles a variety of borderRadius values, animating between them with ease. Specify the radii of all 4 corners in a single string and CSSPlugin will know exactly what to do. Use px, em, % or any unit you want, just like standard css. //applies same value to all 4 corners: TweenMax.to(element, 1, {borderRadius:"25px"}); //unique values for top-left, top-right, bottom-right, bottom-left TweenMax.to(element, 1, {borderRadius:"10px, 4px, 12px, 0px"}); //top-left and bottom-right 10px | top-right and bottom-left 4px TweenMax.to(element, 1, {borderRadius:"10px, 4px"}); The demo below illustrates a variety of ways to animate borderRadius. Sample a variety of borderRadius animations by rolling over each grey shape. TweenMax.to(box, .75, { //all 4 corners borderRadius:"25px" }); TweenMax.to(box, .75, { //all 4 corners borderRadius:"50%" }); TweenMax.to(box, .75, { //top-left and bottom-right | top-right and bottom-left borderRadius:"0px 20px }); TweenMax.to(box, .75, { //top-left | top-right and bottom-left | bottom-right borderRadius:"0px 20px 50px" }); TweenMax.to(box, .75, { //top-left | top-right | bottom-right | bottom-left borderRadius:"0px 20px 50px 50px" }); TweenMax.to(box, .75, { //top-left | top-right | bottom-right | bottom-left borderRadius:"50px 50px 50px 0px" }); clip Browser support: VERY GOOD (Chrome 2, Safari 1.3, Firefox 1, IE 9, Opera 9.2, iOS 3.2, Android 2.1) see details The clip css property controls the clipping region for an absolutely positioned element (that's not a GSAP limitation - that's how it works in plain css too). Any part of an element that would render outside the clipping region will be invisible. This includes the content of the element and its children, backgrounds, borders, outlines, and even any visible scrolling mechanism. You define the rectangle as "rect()" containing a comma-delimited list of four values — top, right, bottom, and left—in that order. Negative length values are allowed. The top and bottom positions are relative to the top border edge of the element’s box. The left and right positions are relative to the left border edge in a left-to-right environment, or to the right border edge in a right-to-left environment. TweenMax.to(element, 0.5, { // rect(top, right, bottom, left) clip:"rect(0px,150px,150px,0px)" }); Move your cursor over the images to see a variety of clip effects. TweenMax.from(img1, 1, {clip:"rect(50px 100px 50px 0px)"}) TweenMax.from(img2, 2, {clip:"rect(100px 0px 100px 0px)"}) TweenMax.from(img3, 2, {clip:"rect(50px 50px 50px 50px)"}) TweenMax.from(img4, 2, {clip:"rect(0px 100px 100px 100px)"}) When doing a from() tween (as demonstrated above) that uses the css clip property the target of the tween must have a clip property applied prior to the tween running. View a simple example or the full demo code. Note: although the sample code on this page uses TweenMax, CSSPlugin works equally well with TweenLite. Just don't forget to load CSSPlugin with TweenLite (it's already included inside TweenMax's js file for convenience). Conclusion There has never been a better time for animation in the browser. Before now, developers had to wrestle with clunky css transitions or css animations which can't accommodate even moderately complex sequences with fine-tuned control over individual properties or deliver solid control over entire sequences, plus they couldn't work around some of the browser bugs (like Safari's major transformOrigin inconsistency or Firefox's randomly disappearing 3D transforms) and they required a bunch of prefixes and redundant code. JavaScript options were very limited as well and none (that we could find) solved some key issues. With GSAP, you can finally get the control and consistency you need and it delivers solid performance as well (much better than jQuery - see the "cage match" for a detailed comparison). Make sure you download a fresh copy of the GSAP JavaScript files from the main GSAP JS page and go have some fun (if you're a Club GreenSock member, you can download it with your bonus plugins from your GreenSock account). If you haven't used GSAP before in JavaScript, check out the Jump Start. Got questions? Drop by the forums and post there.
  17. Note: This page was created for GSAP version 2. We have since released GSAP 3 with many improvements. While it is backward compatible with most GSAP 2 features, some parts may need to be updated to work properly. Please see the GSAP 3 release notes for details. Update: don't miss our guest post on css-tricks.com, Myth Busting: CSS Animations vs. JavaScript which provides some additional data, visual examples, and a speed test focused on this topic. jQuery is the 700-pound gorilla that has been driving lots of animation on the web for years, but let's see how it fares when it steps into the ring with the feisty GSAP (GreenSock Animation Platform) which gained its fame in the Flash world and is now flexing its greased-up muscles in JavaScript. Before we put the gloves on, we need to make it clear that we've got the utmost respect for jQuery, its authors, and its community of users (to which we belong). It's a fantastic tool that we highly recommend for non-animation tasks. This tongue-in-cheek "cage match" is solely focused on animation. Performance Performance is paramount, especially on mobile devices with sluggish processors. Silky smooth animation is the hallmark of any animation platform worth its weight. This round wasn't even close. GSAP was up to 20 TIMES faster than jQuery under heavy stress. See a speed comparison for yourself or make your own. Performance winner: GSAP Controls With jQuery, you can stop an animation but that's about it. Some 3rd party plugins add resume capability, but jQuery takes a pounding in this round. GSAP's object oriented architecture allows you to pause, resume, reverse, restart, or jump to any spot in any tween. Even adjust timeScale on the fly for slow motion or fastforward effects. Place tweens in a timeline with precise scheduling (including overlaps or gaps) and then control the whole thing just like it's a single tween. All of the easing and effects remain perfectly intact as you reverse, pause, adjust timeScale, etc. And you can even kill individual portions of a tween anytime (like if a tween is controlling both "top" and "left" properties, you can kill "left" while "top" continues). Put labels in a timeline to mark important spots and seek() to them anytime. Imagine trying to build the example below using jQuery. It would be virtually impossible. With GSAP, it's easy. In fact, all of the animation is done with 2 lines of code. Drag the slider, click the buttons below, and see how easy it is to control the sequenced animation. See the Pen Impossible with jQuery: controls (used in jquery cagematch) by GreenSock (@GreenSock) on CodePen. Controls winner: GSAP Tweenable Properties jQuery.animate() works with basic numeric properties, but that's about it. If you want to do more, you'll need to rely on lots of 3rd party plugins which may have spotty support or unresolved bugs. GSAP's CSSPlugin handles almost anything you throw at it while protecting you from various browser bugs and prefix requirements. GSAP jQuery  = supported    = supported with 3rd party plugins    = partially supported with 3rd party plugins Basic numeric css properties like left, top, opacity, fontSize, etc. Supported Supported Colors like backgroundColor, borderColor, etc. Supported Supported with 3rd party plugins backgroundPosition Supported Supported with 3rd party plugins boxShadow Supported Supported with 3rd party plugins clip Supported Supported with 3rd party plugins textShadow (including multiple text shadows) Supported Partially supported with 3rd party plugins 2D transforms like rotation, scaleX, scaleY, x, y, skewX, and skewY, including 2D transformOrigin and directional rotation functionality Supported Partially supported with 3rd party plugins 3D transforms like rotationY rotationX, z, and perspective, including 3D transformOrigin and directional rotation functionality Supported Partially supported wiht 3rd party plugins borderRadius (without the need to define each corner and use browser prefixes) Supported Partially supported with 3rd party plugins className allows you to define a className (or use "+=" or "-=" to add/remove a class) and have the engine figure out which properties are different and animate the differences using whatever ease and duration you want. Supported Partially supported with 3rd party plugins Tweenable properties winner: GSAP Workflow When you're creating fun and interesting animations, workflow is critical. You need to be able to quickly build sequences, stagger start times, overlap tweens, experiment with eases, leverage various callbacks and labels, and create concise code. You need to be able to modularize your code by creating functions that each spit back an animation object (tween or timeline) which can be inserted into another timeline at a precise time. You need a flexible, powerful system that lets you experiment without wasting hours wrestling with a limited tool set. jQuery has some nice simple convenience methods like show(), hide(), fadeIn(), and fadeOut(), but GSAP bloodies its nose in this round: GSAP jQuery  = supported    = unsupported Easily create sequences (even with overlapping animations) that can be controlled as a whole Supported Unupported Flexible object-oriented architecture that allows animations to be nested inside other animations as deeply as you want Supported Unupported Animate things into place (backwards) with convenience methods like from() and staggerFrom() Supported Unupported Accommodate virtually any ease including Bounce, Elastic, SlowMo, RoughEase, SteppedEase, etc. Supported Unupported Create a staggered animation effect for an array of objects using one method call (like staggerTo(), staggerFrom(), or staggerFromTo()) Supported Unupported Easily repeat and/or yoyo a tween a specific number of times (or indefinitely) without resorting to callbacks or redundant code Supported Unupported Callbacks for when a tween or timeline starts, updates, completes, repeats, and finishes reversing, plus optionally pass any number of parameters to those callbacks Supported Unupported Place labels at specific times in a sequence so that you can seek() to them and/or insert animations there. Supported Unupported Animate any numeric property of any JavaScript object, not just DOM elements Supported Unupported Call a function whenever the entire platform finishes updating on each frame (like for a game loop) Supported Unupported Workflow winner: GSAP Compatibility Browser inconsistencies and bugs are the bane of our existence as developers. Whether it's the way Internet Explorer 8 implements opacity or Safari's transformOrigin bug that wreaks havok on 3D transforms or the fact that browser prefixes are required to enable many of the more modern browser features, you want your animations to "just work" without having to learn all the annoying hacks. jQuery does a great job of delivering cross-browser consistency overall, but when it comes to animation it falls a bit short mainly because it doesn't even attempt to handle the more modern CSS properties. No JavaScript framework can work miracles and suddenly make IE8 do fluid 3D transforms, for example, but GSAP implements a bunch of workarounds under the hood to solve problems wherever possible. It can do 2D transforms like rotation, scaleX, scaleY, x, y, skewX, and skewY all the way back to IE6 including transformOrigin and directional rotation functionality! Plus it works around scores of other browser issues so that you can focus on the important stuff. Compatibility winner: GSAP Popularity jQuery has been around for a long time and has gained incredible popularity because it does many things well. It's like the Swiss Army knife of JavaScript. There probably isn't a single JavaScript tool that's more popular than jQuery, and GSAP is no exception. As the new kid on the block, GSAP is gonna have to prove itself in the JavaScript community just like it did in the Flash community before it's crowned the undisputed champion. Popularity winner: jQuery Conflict management What happens if there's already a tween running that's controlling a particular object's property and a competing tween begins? jQuery does nothing to manage the conflict - the original tween keeps running. For example, let's say you're animating an element's "top" to 100px and that tween still has 2 seconds left before it's done, and another tween starts running that animates the same element's "top" to 0px over the course of 1 second. It would tween to 0px and then immediately jump to almost 100px and finish that [first] tween. Yuck. GSAP automatically senses these conflicts and handles them behind the scenes. In this case, it would kill the "top" portion of the first tween as soon as the second tween begins. Plus there are several other overwrite modes you can choose from if that's not the behavior you want. Conflict management winner: GSAP Support Both jQuery and GSAP have thriving support forums, but since right now jQuery has a massive user base, you're very likely to find someone with an answer to your question. Even though the GreenSock forums rarely have a question that remains unanswered for more than 24 hours, jQuery's pervasiveness gives it an edge here. On the other hand, GreenSock's forums are manned by paid staff (including the author of the platform), so you're quite likely to get solid answers there. Add to that the fact that GreenSock has a track record of being much more agile in terms of squashing bugs and releasing updates than jQuery, so we'll call this round a tie. Support winner: tie Expandability jQuery and GSAP both offer a plugin architecture, but since jQuery has been out much longer and gained so much popularity, there are numerous plugins available. Some are good, some are not, but there is a thriving community of plugin developers out there. Even though technically they're both equally expandable, the sheer number of plugins currently available for jQuery give it the advantage in this round. Expandability winner: jQuery Learning resources Again, jQuery's popularity trumps anything GSAP could throw at it right now. There are lots of tutorials, videos, and articles about jQuery whereas GSAP is new to the game. GreenSock is being aggressive about putting together solid resources (like the Jump Start tour) and the community is crankin' out some great articles and videos too, but jQuery scores the win in this round. Learning resources winner: jQuery Price & license Both jQuery and GSAP are completely free for almost every type of usage and both allow you to edit the raw source code to fix bugs (if that's something you need to do). If you plan to use GSAP in a product/app/site/game for which a fee is collected from multiple customers, you need the commercial license that comes with "Business Green" Club GreenSock memberships (one-off commercial projects don't need the special license). It's actually a more business-friendly license in many ways than a typical open source license that offers no warranties or backing of any kind or imposes code sharing or credit requirements. GreenSock's licensing model provides a small funding mechanism that benefits the entire user base because it empowers continued innovation and support, keeping it free for the vast majority of users. See the licensing page for details. jQuery employs an MIT license and is free for virtually all uses. As much as we all like "free" software, there's always a cost somewhere. jQuery has a few large corporate sponsors that have helped keep it viable. Both jQuery and GreenSock have long track records of delivering updates, bug fixes, and new features (GreenSock is newer to JavaScript, but served the Flash community since around 2006). Both count some of the largest companies in the world among their user base. Although there are some clear benefits of GreenSocks' license over jQuery's, we'll give this round to jQuery because it is technically "free" in more scenarios than GSAP. Price & license winner: jQuery File size jQuery weighs in at about 32kb gzipped and minified whereas GSAP's TweenLite and CSSPlugin are about half that combined. So in half the size, you're getting significantly more animation capabilities and speed. GSAP is built in a modular fashion that allows you to use just the parts that you need. Of course jQuery serves many other purposes beyond animation, but in this cage match we're focused on animation. Even if you add up TweenLite, TimelineLite, TimelineMax, TweenMax, EasePack, CSSPlugin, BezierPlugin, AttrPlugin, DirectionalRotationPlugin, and RoundPropsPlugin, it's still almost 20% less than jQuery. File size winner: GSAP Flexibility Let's face it: any tweening engine can handle the basics of animating one value to another, but it's really the details and advanced features that make a robust platform shine. GSAP crushes jQuery when it comes to delivering a refined, professional-grade tool set that's truly flexible. All these conveniences are baked into GSAP (no 3rd party plugins required): Tween any numeric property of any object. Optionally round values to the nearest integer to make sure they're always landing on whole pixels/values. Animate along Bezier curves, even rotating along with the path or plotting a smoothly curved Bezier through a set of points you provide (including 3D!). GSAP's Bezier system is super flexible in that it's not just for x/y/z coordinates - it can handle ANY set of properties. Plus it will automatically adjust the movement so that it's correctly proportioned the entire way, avoiding a common problem that plagues Bezier animation systems. You can define Bezier data as Cubic or Quadratic or raw anchor points. Animate any color property of any JavaScript object (not just DOM elements). Define colors in any of the common formats like #F00 or #FF0000 or rgb(255,0,0) or rgba(255,0,0,1) or hsl(30, 50%, 80%) or hsla(30, 50%, 80%, 0.5) or "red". Set a custom fps (frames per second) for the entire engine. The default is 60fps. All tweens are perfectly synchronized (unlike many other tweening engines). Use the modern requestAnimationFrame API to drive refreshes or a standard setTimeout (default is requestAnimationFrame with a fallback to setTimeout) Tons of easing options including proprietary SlowMo, RoughEase and SteppedEase along with all the industry standards Animate css style sheet rules themselves with CSSRulePlugin Animate the rotation of an object in a specific direction (clockwise, counter-clockwise, or whichever is shortest) by appending "_cw", "_ccw", and "_short" to the value. You can tween getter/setter methods, not just properties. For example, myObject.getProp() and myObject.setProp() can be tweened like TweenLite.to(myObject, 1, {setProp:10}); and it will automatically recognize that it's a method and call getProp() to get the current value when the tween starts. Same for jQuery-style getters/setters that use a shared method like myObject.prop(). You can even tween another tween or timeline! For example, TweenLite.to(otherTween, 1, {timeScale:0.5}) would animate otherTween.timeScale to 0.5 over the course of 1 second. You can even scrub the virtual playhead of one tween/timeine with another tween by animating its "time". Use plugins like ThrowPropsPlugin for momentum-based motion, and RaphaelPlugin, EaselPlugin, and KineticPlugin for those [canvas or svg] libraries (Raphael, EaselJS, and KineticJS). Plus there are physics-based plugins like Phyics2DPlugin and PhysicsPropsPlugin as well as a fun ScrambleTextPlugin for Club GreenSock members. Flexibility winner: GSAP Conclusion jQuery eeked out a few decent rounds, but ultimately GSAP left it lying on the mat in a pool of its own blood. Of course we're slightly biased, but check out the facts for yourself. Kick the tires. Audition GSAP on your next project. See how it feels. If you only need simple fades or very basic animation, jQuery is probably just fine. In fact, its fadeIn() and fadeOut() methods are quite convenient. However, what happens when your client wants to do something more expressive? Or what if they start complaining that animation isn't smooth on mobile devices? Why not build on a solid foundation to begin with so that you don't find yourself having to rewrite all your animation code? If you want professional-grade scripted animation, look no further. To get started fast, check out our Jump Start tour. Update: there's now a jquery.gsap.js plugin that allows you to continue using jQuery.animate() but have GSAP drive the animations under the hood, thus delivering much better speed plus a bunch of new properties that you can tween (like colors, 2D and 3D transforms, boxShadow, textShadow, borderRadius, clip, etc.).

  18. Hi everyone, I'm new on this forum, first thanks to Greensock for the awesome library. But... I have a serious problem with the timelineMax. What i want to do: - declare 2 or more timelineMax's with tweens on the same target - calls multiple times in a short time the gotoAndStop method on a (random) timeline. - the latest gotoAndStop must overwrite every other tweens or timelines. The problem is that mostly the latest timelineMax.gotoAndStop is not set. You can see a simple example of my problem in my attachment. Just publish the fla with and without the comments on line 22 to 32. The result should by the same... but it isn't. Can someone help me with that? (I'm sorry for my bad English) Thank you, Pieter example.zip
  19. Hello, I have TimelineMax with multiple instance of TweenMax on it. One of the instances has onComplete that calls itself. I need that to simulate random movements. When I pause TimelineMax everything gets paused except the TweenMax that has onComplete. I kind of get why it is happening but is there way to pause onComplete call? Thanks
  20. Hey folks, maybe it's that I am blind, or just an idiot, but how can I get the moment when the last element of the (staggerTo) array starts tweening? I tried getTweensOf and all kinds of workarounds, but I failed My example: TweenMax.staggerTo(stepArray, tweenSpeed, {alpha:1, scaleX:1.5, scaleY:1.5, dropShadowFilter:{blurX:15, blurY:15, distance:5, alpha:0.33}, ease:Cubic.easeInOut, onComplete:tweenScaleDown, onCompleteParams:["{self}"]}, stepStaggerAmount); Sorry if that's a dumb question, but I tried stuff for hours now and cant get it. TIA, Lasercode
  21. Hi all! First off thanks for everything...! So... I have created a "Player" class which extends MovieClip and contains an array of F4V files being loaded via LoaderMax.parse ... In my Main Document Class (Main) I want to transform properties of the entire Player class (alpha, scale, etc.) however the F4V does not see the transformations....It seems I have to reference the content directly within the Main class. For example, if i simply try to set player.visible=false, after i've already added video content to the stage, It does not stick, but if I reference player.video.content.visible=false, it works... What I'm really trying to do is fade the player object out before I navigate back to a main navigation screen. I can fade each video.content individually but I'd rather just write one tween that effects the whole class. Am I missing something simple or is this larger than I think? ...additionally, these transformations DO work with NetStream driving the f4vs. But looping w netStream is ugly , as we know. Thanks!
  22. Hi folks, I am not really new to this, but I get a hard time trying to do the following: I got an array of MCs named "stepArray". I want to animate through it after a dice function which gives me a number between 1 and 6 (if 5, the stepArray will have 5 elements and so on). Whatever, I need to know when the last element of the array has finished tweening, because that is the time the dice can be used again and is set free. If you need more input, please reply. function animatePlayerMove ():void { tweenScaleUp(); } function tweenScaleUp():void { TweenMax.allTo(stepArray, tweenSpeed, {alpha:1, scaleX:1.5, scaleY:1.5, dropShadowFilter:{blurX:15, blurY:15, distance:5, alpha:0.33}, ease:Cubic.easeInOut, onComplete:tweenScaleDown}, stepStaggerAmount); } function tweenScaleDown():void { tma = TweenMax.allTo(stepArray, 0.2, {alpha:1, scaleX:1, scaleY:1, dropShadowFilter:{blurX:5, blurY:5, distance:5, alpha:0.33}, ease:Cubic.easeInOut}, stepStaggerAmount); addEventListener(Event.ENTER_FRAME, checkStepAnimationprogress); } function checkStepAnimationprogress (e:Event):void { if(tma[tma.length-1].currentProgress == 1){ //This doesnt work properly even with totalProgress trace("STEP ANIMATION ENDS HERE"); removeEventListener(Event.ENTER_FRAME, checkStepAnimationprogress); activateDice(); } } Obviously there is some mistake in my logics and I hope someone here will help. TIA, Lasercode
  23. Hi Guys, I seem to have a problem with the tweenMax.updateTo method. Given this sample code: _tween = new TweenMax(myMc,2,{rotation:360,repeat:-1,onUpdate:onUpd, ease:Linear.easeNone}); function onUpd():void{ if(_stop){ _tween.updateTo({repeat:1,rotation:_angleToStop, onComplete:onF},true); } } I am expecting the _tween to update 1. its rotation value to the predetermined value in _angleToStop 2, repeat count to change from infinity (-1) to 1 3. for it to call the onComplete method once that 1 rotation is done, where it stops in the correct value; What actually happens is the spinning starts to slow down as i would expect as it is reaching the target value however it then start animating again... Its like the repeat is not working.. Could anyone help me? Seems weird. Thanks, Bynho
  24. Hey guys... This is my first post to this forum... I am working on a project and i want to have a tweening effect similar to the 'Custom Presets : fly-in pause fly-out' option in Flash IDE. Its just that i want to create it with action script and want to control it properly through code. For the rest of the tweening in my project i am using 'Greensock's TweenMax'. So if someone can help me creating the same effect in this engine it would be helpful. Thanks.
  25. Obviously addChild(mc1); works on a single clip, but how would I bring the current movie clip in the sequence to the front? Thanks. Here's my code. var mcArray:Array = new Array(mc1,mc2,mc3,mc4,mc5); var timeline:TimelineMax = new TimelineMax({repeat:1}); timeline.insertMultiple (TweenMax.allTo(mcArray, 2, {bezierThrough:[{z:0}, {z:-200}, {z:0}], orientToBezier:false, ease:Linear.easeNone}, 1));
