  1. Dear GSAP and fellow GSAP users. Although I found a workaround, as I expand my usage of your api, I thought it might be useful for me, and maybe others, to create a discussion based on what I encountered I've added a codepen as this is good practice, but it's a completely stripped down version of what is actually happening, as it is not possible to include everything, and what I'm after, seems to me to be something fairly straight forward. Scenario I have a timeline (small snippet in codepen) that simply animates some text, but which includes calls (removed from codepen) to external (unconnected to the animation) functionality. The timeline works great, and all the controls I've included do exactly as expected - accept that what I want to happen is when a user pauses the anim, the text acts gracefully and moves back to the starting position (css only, not timeline), as I don't want the text just to be stuck mid flow. I handle the external calls perfectly and the paused state is fine, all I want is the css side to be cleared. Ok so I tried the clearProps:transform || all etc (via a set command, and injected at different time points**), I also removed props/data/attr etc etc, but the transform on the text resolutely remains, if the timeline is either playing or paused. If I clear first, then clearProps works. For completeness, I tried killing the current tween (which I don't want,but as a test), didn't do anything. I tried using the timelinemax calls to get current/before/after labels, but since this moves the play head, but not the external function calls, I cannot use this. **Now I've read conflicting posts that say it is possible to use clearProps on working timelines as GSAP doesn't force continual transforms, and others that say it is not supposed to work in that way. I believe the default is for overwrite between tweens so wouldn't this allow another tween to take precedence? I'm pretty sure a tween is added to the end of the stack, as per api and probably explains what I'm seeing. I used $('.key-shortcuts').children().removeAttr("style"), which seems a rather blunt force approach, as it clears all styling, whether GSAP related or not. (but then looking at the code I think clearprops does the same?) Based on my scenario what would be the GSAP way to clear (or manipulate) the added css in a working timeline paused or otherwise? One final question, I quite often want to base one tween in relation to a previous label, but also want to label that very same tween. e.g. t1.to(some el,1,{some css},"label1+=1","but also be labeled itself?"); Is that possible? Btw, GSAP is just great, I had used it before mainly for the performance boost, standalone or as a jquery override, but for some reason I missed the timeline aspects. It's brilliant, I've already started removing the hugely ugly jquery way Thanks in advance
  2. I came across an unexpected behaviour: apparently Chrome 36 and up supports both prefixed and unprefixed 'transform' property. So, if you set initial transform values on an element (not with GSAP) like so: someElement { -webkit-transform:rotate(30deg); transform:rotate(30deg) } and do TweenMax.set(someElement, {clearProps: 'transforms'}) only the unprefixed version is being cleared and the rotation remains on the element.
  3. Hi there, I am using the Quart.easeOut easing on all my animations. On some parts of my website, I would like to use the same easing but using CSS. How can I find the bezier function of Quart.easeOut?
  4. Hi, I'm looking at animating an Absolutely positioned (in the center) to specific percentage on the left-margin. I can get it to work as long as the marginLeft isn't set before hand other than in the CSS, but when the element has that left-margin style inline and then I tween to say 4%, it jumps all the way to the left and then moves the 4%. I have a codepen setup, if you comment out the marginLeft and marginRight and only have that set in the CSS it works correctly. Am I thinking about margins (and absolutely positioned elements) incorrectly? http://codepen.io/kaplan/pen/rmKzG Thanks, Dave
  5. I just recently discovered GSAP and have been so impressed by how powerful and intuitive it is. I'm wondering if anyone knows of a Javascript solution that does for CSS layout what GSAP does for CSS animation? I know this isn't considered good practice to manage layout with Javascript, but I'm just wondering if there are any good options out there. Thank you!
  6. Is it possibe to scale a div with TweenMax but I would like to maintain or reset the CSS top and left position? Below are a few failed attempts. It seems TweenMax always scales from the center point. TweenMax.fromTo('#div-name', 2, {scaleX:.5, scaleY:.5}, {css:{top:0, left:0}}); or TweenMax.to('#div-name', 2, {scaleX:.5, scaleY:.5}); $("#div-name").css({ top: '0px', left: '0px' }); The Codepen URL shows the red div scaling but not maintaining the top: 0 and left: 0 desired position.
  7. Hey guys. I'm doing a simple tween on a score bar which tweens the width of a div from 0% to 0-100% depending on the users score in a game. I want to play a sound when the bar animates and passes various points. I'm struggling to get the % value back out of my tween instance during the onUpdate callback. tween.target is an array containing my div. I can call: onUpdate: function() { # get a numeric percentage value val = parseFloat(this.target[0].style.width) if(val > 0 && !played_one) { soundManager.play('sfx','score_1'); played_one = true; } else if(val > 50&& !played_two) { soundManager.play('sfx','score_2'); played_two = true; } else if(val > 90 && !played_three) { soundManager.play('sfx','score_3') played_three = true; } } This solution isn't the most elegant I know. But something really doesn't feel right about "this.target[0].style.width" I'm not 100% that this is going to give me the current percentage value correctly in all browsers. I thought there might be a GSAP to give me this value reliably.
  8. With CSS 3 I am able to use keyframes, which makes animating objects really flexible. For example, with keyframes I can change a object opacity from 0 to 1 at 50% of the animation and then back to 0 at 100% of the animation... that creates a smooth fadein and fadeout. I am trying to accomplish the same with gsap. With TweenMax I can set a fromTo... but how, would I go about doing a fromTofrom? I tried doing something like this: var mydiv = new TimelineMax() .add(TweenMax.fromTo($(".mydiv"), 1, {opacity:0, scale:0}, {opacity:1, scale:1})) .add(TweenMax.fromTo($(".mydiv"), 1, {opacity:1, scale:1}, {opacity:0, scale:2})); However, when using "add", there's a very small delay between the first and the second add. How do I go about removing that delay? Or, is there another way of doing chained animations?

    margin auto

    Help plz. Inner block jumps to a horizontal alignment without animating itself there. Initially I was running both animations simultaneously and so I thought that perhaps the inner block may not know the horizontal dimensions to calculate margin auto if the outer block is animating its 'left' attribute, but it turns out that the animation doesn't work even after the outer block finished animating. Thanks for the help!
  10. Hi all I don't have any code for my question about css pseudo-class usage. I'd like to build ::after and ::before with set() and i failed. So in my wishes i'd like to make a cool animation with ::after ans ::before and I'm afraid to fail again. I saw a tuto on GreenStock which speak about CSSRulePlugin (here) but I don't know if this plugin is in the TweenMax.min.js file that I utilise to be sure to have the max of possibility. hummm I think i'm a little bit lost thank you for your help
  11. Has anyone done any work with Greensock 3D transforms to create dynamic perspective shadows with CSS3? I was thinking this morning that it would most likely not be that difficult, but my 3D math/trigonometry skills are somewhat dormant. What I mean is shadows that will fall on a flat horizontal plane ("the ground") behind the object, as at sunset, and will, as the object moves in x and z directions (not y, as that seems complicated). The shadows would respond to a central light point (perhaps the center of the screen) Something like this image — Thanks for any way forward —
  12. hi! I'm doing something a bit like this; TweenMax.to(element, 0.3, {className:'+=over'}); where the .over class has different colour, position etc, but also different background-position. My problem is, i'd like the background-position to not tween, while the rest of the properties do. is there a way to add an exception to the tween? Any ideas? thanks, Andy
  13. Hi I'm playing with some "clip" animations right now, and find myself calculate way too many hardcoded values. [Edit: this functionality exist, I still wish for the array option] I think that an addition of relative values to clip:rect() will add a lot of flexibility. Also, allowing clip to receive an array of values instead of the CSS syntax rect(a,b,c,d) could help ease development too. something like so: // set initial clip:rect(0, 100px, 100px, 0) as required by CSS TweenMax.set(element, {clip: [0, 100, 100, 0]}) // tween from clip:rect(50px, 80px, 100px, 0) TweenMax.from(element, {clip: ['+=50', '-=20', '+=0', '+=0']}))
  14. So i'm currently working on a page that has animation when you scroll down the page using scrollmagic and tweenmax. I've pinned the appropriate sections and created the animation, and everything works perfectly. I then added some javascript to have a show/hide function for the different features in a sticky nav (instead of having a long vertical scrolling page, it swaps out content within the same area). I noticed a very weird bug when I switch between the different sections. Here's a screenshot of what the bug looks like when I go back to the original section with the animation. It seems as though the tweenmax plugin is ignoring all of my css and completely breaks. What's even weirder is that when you start to scroll down the css is restored. Any ideas on what this is? I can't seem to figure out what's causing it.
  15. I'm using the greensock animation library to animate the translateZ property of an image. This is my code: $("<img />") .attr({ src: piece, class: "pieces" }) .hover(function() { tl.to($(this), 1, {transform:"translateZ(1px)"})}, function() { tl.fromTo($(this), 1, {transform: "translateZ(0px)"}) }) .load(function () { _stageElement.append($(this)); }) } But instead of stopping at 5px it flies completely off the screen. Does anyone know what's happening here and why? Also if it's important after the image flies off the screen, it comes back to its original location, but the hover property doesn't have any effect anymore. I'm not sure if this is a greensock issue or a jquery issue. Here's an example to see what I mean http://richbaird.net/3dFlip/fip.html

    CSSRulePlugin

    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. Allows TweenLite and TweenMax to animate the raw style sheet rules which affect all objects of a particular selector rather than affecting an individual DOM element's style (that's what the CSSPlugin is for). For example, if you have a CSS class named ".myClass" that sets background-color to "#FF0000", you could tween that to a different color and ALL of the objects on the page that use ".myClass" would have their background color change. Typically it is best to use the regular CSSPlugin to animate css-related properties of individual elements so that you can get very precise control over each object, but sometimes it can be useful to tween the global rules themselves instead. For example, pseudo elements (like :after, :before, etc. are impossible to reference directly in JavaScript, but you can animate them using CSSRulePlugin as shown below. See the Pen CSSRulePlugin by GreenSock (@GreenSock) on CodePen. Learn more in the CSSRulePlugin documentation.
  17. I am trying to animate back and forth between two css classes and I'm having some issues right now I have two classes "contracted" and "expanded: .button{ border: 5px #000 solid; } .contracted{ width:100px; height:100px; background-color:green; } .expanded { width:200px; height:200px; background-color:red; } And im trying to switch between them with: $( ".button" ).click(function() { TweenMax.to(".contracted",2,{css:{className:"+=expanded"}}).set(".contracted",{delay:5,css:{className:"-=contracted"}}); TweenMax.to(".expanded",2,{css:{className:"+=contracted"}}).set(".expanded",{delay:5,css:{className:"-=expanded"}}); }); http://codepen.io/anon/pen/vzayE And it will tween from "contracted" to "expanded"... but not vice-versa... Is there a proper way to switch classes?
  18. Hey there, is it possible to tween both shadow Inset and the outside shadow at the same time??
  19. Hi guys, Just trying to achieve the CSS animation transforms with GSAP. I am getting different results while using same properties. How can I achieve results like in CSS animation? I am doing something wrong? Here is the code: http://codepen.io/praneybehl/pen/Gbmhs Thank you for the help. Praney
  20. Hi everyone this is my problem, i making a little practice and i want rotate a image but i don´t want use CSS only script var img; function init(){ ctx = document.getElementById("canvas").getContext("2d"); img = new Image(); img.src = "http://postimg.org/image/qj0abntbh/"; img.xpos = 50; img.ypos = 10; img.onload = function() { TweenLite.ticker.addEventListener("tick", loop); } function loop(){ ctx.clearRect(0, 0, 800, 600) ctx.drawImage(img, img.xpos, img.ypos); } TweenMax.to(img, 7, { rotation: 360, delay:2.2, repeat: 5}); } thanks
  21. Im pretty new to tweenmax, and i was wondering how to create an mouseover effect like seen on this page (hover over the images) : http://www.fcinq.com/ (scroll down to the work) They are using this in the css: transform: scale(0.25, 0.1); transition: background 0.3s linear 0s, transform 0.4s cubic-bezier(0.19, 1, 0.22, 1) 0s; and on the hover: transform: scale(0.7); transition-delay: 0.2s; However, I have no idea how to do this in TweenMax?
  22. 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. A post by Carl Schooff, GreenSock's "Geek Ambassador" Hot on the heels of the CSS Myth-Busting article, I'm going to take a deeper look into CSS Animations and how they fit (or don't fit) into a modern animator's workflow. This isn't about simple fades or basic transitions (CSS is great for those); Developers who use animation to tell a story or deliver rich interactivity require a very different workflow than those who are simply doing UI transitions. I'm going to show you exactly where some of the pain points are for a typical project and how they can bring your workflow to a grinding halt. Even relatively simple animations like the one below can become surprisingly cumbersome with CSS. Example of a Simple, "Story-Telling" Animation See the Pen GSAP: Full Version Complete by GreenSock (@GreenSock) on CodePen. Seriously, You guys are beating up on CSS Animations again? Really, I'm not trying to be negative for the sake of being negative. It's just that so many developers are looking for animation tools that accommodate their real-world projects and the industry seems to scream "use CSS!" even though the API doesn't adequately serve the workflow of modern animators who are building immersive experiences or animations that "tell a story". Too many people are being led down a path that results in utter frustration, or at least a lot of wasted time. And no, CSS Animations aren't "evil". In fact, sometimes they're perfectly appropriate (see the CSS Myth-Busting article for details). There are CSS fans who craft animations and proudly shout "Pure CSS! No JS!" as if the grueling effort necessary is a badge of honor. The accomplishment is indeed admirable, and we tip our hats to them. But WOW it's a lot of work and doesn't exactly lend itself to experimentation or easy edits. Quite simply, we aim to change the tide with tools like GSAP. The majority of the GSAP API has been shaped by feedback from real developers in the trenches over the course of many years. The process of animation should be fun and inspiring. Challenge! Still not convinced that GSAP is better suited for professional animators? I'm very interested to see how this animation can be built more effectively. Are you in the CSS-Purist camp? Do you prefer to trigger animations with JavaScript setTimeouts? Maybe you have another library that blows GSAP away. Dig in and build the animation I've been using with your own choice of tools. Below are some resources that should make it easy to get started. When you're done, just drop us a line in the comments or in the forums.

  23. I'm happy to say GSAP has given me hope again. I switch from jQuery animations (and some css3 jquery plugins) to GSAP tweens and instant performance gains! However, I'm still not happy with the performance I get on my Samsung Galaxy S2x. It's a pretty decent phone so I know it has the power to play some high end games. I think using phonegap's browser plugin caused some issues, but even using mobile chrome the performance is choppy and not good enough for a production app. Of course, I could be doing something very wrong as I'm new to the mobile HTML5 scene. I'm hoping someone might be able to help determine if my issue is animation related or just bad code in general. My animations are pretty simple: TweenLite.to(jem, animationSpeed, {top:(blockSize*row)}); It's maybe all the other stuff that gets in the way? I've put everything in jsbin for easy viewing in browser and on mobile devices: http://jsbin.com/uyAXume/9/edit Thanks for any help or pointers.
  24. Might be doing something wrong here, but I'm curious if anyone else has had this issue. I am trying to animate the border of an input area from 0 to a width back to 0. Going from a width to 0 works fine, but going from 0 to the width immediately jumps to the width while everything else animates. I've made an exaggerated example here: http://jsfiddle.net/Haxen2000/Df8xj/ The original margin is what the border width should be; just made it larger so the issue is more visible. Thanks!
  25. Hi everybody, First of all, gratz for the amazing work you've done Jack, Carl and all the community's member who help the development of GreenSock. (and sorry for my bad English). i use TweenMax for 4 years in my projects AS3 in Flash and now i try to convert me to HTML5 with GSAP. I want to be able to convert all the work ive done for these 4 years in HTML5 and so ive decided to work with the more complex animation. The matter with this animation is the number of element animated (i join it to the message). I don't intend to declare all the element one by one, in CSS, this will be a wasted time I think. So, ive searched on the web but I found nothing that I can use. I work with Adode Design Premium CS5, so i can't use CreateJS as plugin for Flash and I haven't Edge Animate. I tried Swiffy but It doesn't seems to work. I tried to do something like this in Flash: function createCSS () { for (var i:int=0; i<numChildren-1; i++) { var mc:MovieClip = getChildAt(i) as MovieClip; tabMC[i] = mc; trace ('#'+mc.name+'{'); trace ('position:absolute;'); trace ('x:'+mc.x+';'); trace ('y:'+mc.y+';'); trace ('}'); trace (''); } } wich display a "potential" CSS style-sheets of all the elements but if I want it works, i will have to export each element in SVG with Illustrator with the same name used by Flash, and that also seems to be a wasted time. Is there another solution you see to do this ? I hope Ive been clear, my english is so bad. Thank you in advance for whatever help you can give me. Notice that the animation size is very low (52ko) i want to keep this size as lower as possible, even in HTML5. ps: attached file contains the .fla ATRT_anim01.zip
