  1. I am trying to create a website using the background effect exactly similar as implemented in this website, http://brightmedia.pl/ . On inspect element the div that creating the parallax effect on background from mouse move and scroll as well, we can see that it is changing the translate3D() property of the element on mouse move. Please guide me how can I achieve this same background effect?
  2. I have an error on this code that I can't understand why keeps showing. //Inline Promotion GSAP animation console.clear(); const threshold = 0.7; // trigger const options = { root: null, rootMargin: '0px', threshold: threshold }; const observer = new IntersectionObserver(animHandler, options); const ar = Array.from(document.querySelectorAll(".two-column-promo-container")); const animations = ar.map(el => (observer.observe(el), new TimelineMax({paused:true}))); var promoLeft = $(".two-column-promo-float-left .two-column-promotion"), promoRight = $(".two-column-promo-float-right .two-column-promotion"), featureLeft = $(".two-column-promo-float-left .two-column-feature"), featureRight = $(".two-column-promo-float-right .two-column-feature"); TweenMax.set("promoLeft, promoRight, featureLeft, featureRight"); // timeline for each section animations[0].from(promoLeft, 1.8, {y:-400, opacity: 0.0, delay:0.0, }); animations[1].from(promoRight, 1.8, {y:-400, opacity: 0.0, delay:1.0, }); animations[2].from(featureLeft, 1.8, {y:-400, opacity: 0.0, delay:0.0, }); animations[3].from(featureRight, 1.8, {y:-400, opacity: 0.0, delay:1.0, }); // observer handler function animHandler(targets, observer) { for (var entry of targets) { if (entry.isIntersecting) { let i = ar.indexOf(entry.target); animations[i].play(); } else { return; } } }
  3. 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. As the author of GSAP I'm sometimes asked if the Web Animations API (WAAPI) will be used under the hood eventually. My responses have gotten pretty long so I thought I'd share my findings with everyone here. Hopefully this sheds light on the challenges we face and perhaps it can lead to some changes to WAAPI in the future. WAAPI is a native browser technology that's similar to CSS animations, but for JavaScript. It's much more flexible than CSS animations and it taps into the same mechanisms under the hood so that the browser can maximize performance. Support is a bit spotty right now and there are multiple levels to the spec, so some browsers may support only "level 1", for example, but the hope is that eventually all major browsers will support WAAPI fully. Progress in that direction has been very, very slow. You could think of WAAPI almost like a browser-level GSAP with a bunch of features stripped out. This has led some to suggest that perhaps GSAP should be built on TOP of WAAPI to reduce file size and maximize performance. Ideally, people could tap into the rich GSAP API with all of its extra features while benefiting from the browser's native underpinnings wherever possible. Sounds great, right? Unfortunately, WAAPI has some critical weak spots that make it virtually impossible for GSAP to leverage it under the hood (at least in any practical manner). I don't mean that as a criticism of WAAPI. In fact, I really wanted to find a way to leverage it inside GSAP, but I'll list a few of the top reasons why it doesn't seem feasible below. To be clear, this is NOT a feature comparison or a bunch of reasons why GSAP is "better" - these are things that make it architecturally impossible (or very cumbersome) to build GSAP on WAAPI. Custom easing WAAPI only supports cubic-bezier() for custom easing, meaning it's limited to one segment with two control points. It can't support eases like Bounce, Elastic, Rough, SlowMo, wiggle, ExpoScaleEase, etc. GSAP must support all of those eases plus any ease imaginable (unlimited segments and control points - see https://greensock.com/customease). This alone is a deal-breaker. Expressive animation hinges on rich easing options. Independent transform components The most commonly animated values are translation (x/y position), rotation, and scale (all transform-related) but you cannot control them independently with CSS or WAAPI. For example, try moving (translate) something and then halfway through start rotating it and stagger a scale toward the end: |-------- translateX() ------------| |------ rotate() ------| |---------- translateY() -----------| |-------------- scale(x,y) --------------| Animators NEED to be able to independently control these values in their animations. Additive animations (composite:"add") probably aren't an adequate solution either. It's unrealistic to expect developers to track all the values manually or assume that stacking them on top of each other will deliver expected results - they should be able to just affect the rotation (or whatever) at any time, even if there was a translate() or scale() applied previously. GSAP could track everything for them, of course, but continuously stacking transforms on top of each other seems very inefficient and I imagine it'd hurt performance (every transform is another matrix concatenation under the hood). There is a new spec being proposed for translate, scale, and rotate CSS properties which would certainly help, but it's not a full solution because you still can't control the x/y components independently, or all of the 3D values like rotationX, rotationY, z, etc. This is an essential feature of GSAP that helped it become so popular. Example See the Pen Independent Transforms Demo by GreenSock (@GreenSock) on CodePen. Custom logic on each tick Certain types of animations require custom logic on each tick (like physics or custom rounding/snapping or morphing). Most GSAP plugins rely on this sort of thing (ModifiersPlugin, for example). I'm pretty sure that's impossible with WAAPI, especially with transforms being spun off to a different thread (any dependencies on JS-based logic would bind it to the main thread). Non-DOM targets As far as I know, WAAPI doesn't let you animate arbitrary properties of generic objects, like {myProperty:0}. This is another fundamental feature of GSAP - people can use it to animate canvas library objects or generic objects...whatever. Global timing controls I don't think WAAPI lets you set a custom frame rate. Also, GSAP's lag smoothing feature requires the ability to tweak the global time (not timeScale - I mean literally the current time so that all the animations are pushed forward or backward). As far as I know, it's impossible with WAAPI. Synchronization (transforms and non-transforms) As demonstrated in this video, one of the hidden pitfalls of spinning transforms off to another thread is that they can lose synchronization with other main-thread-based animations. As far as I know, that hasn't been solved in all browsers. We can't afford to have things getting out-of-sync. Some have proposed that GSAP could just fall back to using a regular requestAnimationFrame loop to handle things that aren't adequately supported by WAAPI but that puts things at risk of falling out of sync. For example, if transforms are running on a separate thread they might keep moving while other parts of the animation (custom properties that get applied somehow in an onUpdate) slow down or jank. Compatibility GSAP has earned a reputation for "just working" across every browser. In order to deliver on that, we'd have to put extra conditional logic throughout GSAP, providing fallbacks when WAAPI isn't available or doesn't support a feature. That would balloon the file size substantially and slow things down. That's a tough pill to swallow. WAAPI still isn't implemented in several major browsers today. And then there are the browser inconsistencies (like the infamous SVG origin quirks) that will likely pop up over time and then we'd have to unplug those parts from WAAPI and maintain the legacy raw-JS mechanisms internally. Historically, there are plenty of cross-browser bugs in natively-implemented technologies, making it feel risky to build on top of. Performance WAAPI has a performance advantage because it can leverage a separate thread whereas JavaScript always runs on the main thread, right? Well, sort of. The only time a separate thread can be used is if transforms and/or opacity are the only things animating on a particular element (or else you run into synchronization issues). Plus there's overhead involved in managing that thread which can also get bogged down. There are tradeoffs either way. Having access to a different thread is fantastic even if it only applies in certain situations. That's probably the biggest reason I wanted to leverage WAAPI originally, but the limitations and tradeoffs are pretty significant, at least as it pertains to our goals with GSAP. Surprisingly, according to my tests GSAP was often faster than WAAPI. For example, in this speed test WAAPI didn't perform as well as GSAP on most devices I tried. Maybe performance will improve over time, but for now be sure to test to ensure that WAAPI is performing well for your animations. File Size To ensure compatibility, GSAP would need all of its current (non-WAAPI) code in place for fallbacks (most browsers won't fully support WAAPI for years) and then we'd need to layer in all the WAAPI-specific code on top of that like conditional logic checking for compatible eases, sensing when the user is attempting something WAAPI can't support, tracking/stacking additive animations, etc. That means file size would actually be far worse if GSAP were built on WAAPI. Some have suggested creating a different adapter/renderer for each tech, like a WebAnimationsAdapter. That way, we could segregate the logic and folks could just load it if they needed it which is clever but it doesn't really solve the problem. For example, some plugins may affect particular CSS properties or attributes, and at some point conditional logic would have to run to say "oh, if they're using the WebAnimationsAdapter, this part won't work so handle it differently". That conditional logic generally makes the most sense to have in the plugin itself (otherwise the adapter file would fill up with extra logic for every possible plugin, bloating file size unnecessarily and separating plugin logic from the plugin itself). So then if anyone uses that plugin, they'd pay a price for that extra logic that's along for the ride. Weighing the Pros & Cons At the end of the day, the list of "pros" must outweigh the "cons" for this to work, and currently that list is quite lopsided. I'd love to find a way to leverage any of the strengths of WAAPI inside GSAP for sure, but it just doesn't seem feasible or beneficial overall. The main benefit I see in using WAAPI inside GSAP is to get the off-the-main-thread-transforms juice but even that only seems useful in relatively uncommon scenarios, and it comes at a very high price. I'm struggling to find another compelling reason to build on WAAPI; GSAP already does everything WAAPI does plus a lot more. I'm hopeful that some of the WAAPI benefits will someday be possible directly in JS so that GSAP wouldn't have to create a dependency on WAAPI to get those. For example, browsers could expose an API that'd let developers tap into that off-the-main-thread transform performance. Ideally, browsers would also fix that hacky matrix()/matrix3d() string-based API and provide a way to set the numeric matrix values directly - that'd probably deliver a nice speed boost. Please chime in if I'm missing something, though. (Contact us or post in the forums) Why use GSAP even if/when WAAPI gets full browser support? Browser bugs/inconsistencies Lots of extra features like morphing, physics, Bezier tweening, text tweening, etc. Infinite easing options (Bounce, Elastic, Rough, SlowMo, ExpoScaleEase, Wiggle, Custom) Independent transform components (position, scale, rotation, etc.) Animate literally any property of any object (not just DOM) Timeline nesting (workflow) GSDevTools Relative values and overwrite management from() tweens are much easier - you don't need to get the current values yourself Familiar API Why WAAPI might be worth a try If you don’t need broad browser support today or any of GSAP’s unique features, you could save some kb by using WAAPI Solid performance, especially for transforms and opacity Always free Again, the goal of this article is NOT to criticize WAAPI at all. I think it's a great step forward for browsers. I just wanted to explain some of the challenges that prevent us from using it under the hood in GSAP, at least as it stands today. EDIT: Brian Birtles, one of the primary authors of the WAAPI spec, reached out and offered to work through the issues and try to find solutions (some of which may involve editing the spec itself) which is great. Rachel Nabors has also worked to connect people and find solutions. Although it may take years before it's realistic to consider building on WAAPI, it's reassuring to have so much support from leaders in the industry who are working hard to move animation forward on the web.
  4. I want to animate the home page of my website like this one : http://discoveroutpost.com/ I am using GSAP TweenMax function but unable to get the smooth animation like this. I am also trying the ScrollMagic Library for it but still no luck. Please guide how can I achieve this. Thanks in advance.

    GSDevTools

    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. Your animation workflow is about to get a major boost. GSDevTools gives you a visual UI for interacting with and debugging GSAP animations, complete with advanced playback controls, keyboard shortcuts, global synchronization and more. Jump to specific scenes, set in/out points, play in slow motion to reveal intricate details, and even switch to a "minimal" mode on small screens. GSDevTools makes building and reviewing GSAP animations simply delightful. Get Started Load the JavaScript file //be sure to use a path that works in your dev environment Requirements GSDevTools requires TweenMax (well, actually just CSSPlugin, TweenLite, TimelineLite, AttrPlugin which are all included in TweenMax) version 1.20.3 or higher. It also uses Draggable under the hood, but in order to minimize hassle for end users, Draggable is included inside the GSDevTools file itself. How do I get it? GSDevTools is available to Club GreenSock members ("Shockingly Green" and above). Just download GSAP with the bonus files zip from your Dashboard. Try GSDevTools for free on CodePen. FAQ Why is my Global Timeline 1000 seconds long? That means you've probably got an infinitely repeating animation somewhere. GSDevTools caps its duration at 1000 seconds. Scrubbing to Infinity is awkward. Does loading GSDevTools impact runtime performance? Since it must monitor and record the root timeline, yes, there is a slight performance hit but probably not noticeable. Keep in mind that usually you'll only load GSDevTools while you're developing/reviewing your animations and then remove it when you're ready to launch, so ultimately it shouldn't be much of a factor anyway. Why isn't GSDevTools in the CDN or Github repo? Because it's a membership benefit of Club GreenSock. It's a way for us to give back to those who support our ongoing development efforts. That's why we've been able to continue innovating for over a decade. See https://greensock.com/why-license for details about our philosophy. Does GSDevTools work with other animation libraries? Nope, it depends on some unique capabilities baked into the GSAP architecture. What will I do with all the time this tool saves me? Take up a new hobby, ponder deep philosophical questions, make cookies - it's up to you.
  6. Hi everyone! I would like to create a quotes rotator with SplitText and Timeline Stagger which can be animated in lines or words or chars! I have already tried to create one and there is the Pen that I made below here but it is not really what I wanted to achieve!! I would very appreciate any kind of help. Thank you!
  7. Hi All, I've been using GSAP for 2 months now and It has saved me a LOT of time and headache. It is an awesome library. Recently I discovered that I can use Scroll Magic library with GSAP and I've been trying to make an animation using both of them. Here's the link to my codepen demo: The idea is that as we scroll down the page, the text "DESIGNWORX" should translate to the left and at the same time opacity should animate from 1 to 0. I've achieved that. The problem I'm facing is that I want to reverse this animation i.e the text "DESIGNWORX" should translate back and opacity animate from 0 to 1 ONLY when I reach the top of my page while scrolling back. I've tried to do that by using "triggerHook" method as you can see in my pen but sadly I've failed. I've also searched all over the internet for answers but all in vain. I was hoping if someone could help me in this regard. I'm not an expert in javascript and would really appreciate any tips or help. Thanks in advance! Ali
  8. Hi I'm trying to replicated the transitions on this pages sections http://cuberto.com using TweenMax. var slides=document.querySelectorAll('.slide'); var tl=new TimelineLite({paused:true}); for(var i=slides.length;i--;){ var D=document.createElement('div'); D.className='Dot'; D.id='Dot'+i; D.addEventListener('click',function(){ tl.seek(this.id).pause() }); document.getElementById('Dots').appendChild(D); tl.add('Dot'+i) if(i>0){ if(i!=slides.length-1) { tl.addPause() } tl .set(slides[i-1].getElementsByClassName("sideDetails"), {width: "0"}) .fromTo(slides[i].getElementsByClassName("sideDetails"), .3, {width:'50%'},{ width: "100%", ease: Power2.easeInOut}) .to(slides[i].getElementsByClassName("detailsText"), .3, {opacity: "0", y:"-=60", ease: Power2.easeInOut},0) .set(slides[i],{ background: "none"}) .fromTo(slides[i].getElementsByClassName("sideDetails"), .3, {x: "0%"},{ x: "100%", ease: Power2.easeInOut}, .3) .to('#Dot'+i,.7,{backgroundColor:'rgba(255,255,255,0.2)'},'L'+i) .set(slides[i],{zIndex:1-i}) .set(slides[i-1],{zIndex:slides.length}) .to(slides[i-1].getElementsByClassName("sideDetails"), .3,{width: "50%",ease: Power2.easeInOut}, .6) .fromTo(slides[i-1].getElementsByClassName("detailsText"), .3, {opacity: "0", y:"-=60" }, {opacity: "1", y:"0",ease: Power2.easeInOut},.6) }; }; full code at codepen can be found here I'm basically trying to transition between a bunch of sliders with a swipe animation, I have alternated the element i would like to transition on each slide in black or pink so I can see the animation. I can seem to isolate the animation to the current slide - in essence I want the left hand div to grow to 100%, then animate off the page to the right, then switch to the next slider and animate the left hand dive to a width of 50% from an initial state of 0. I believe that is what the Cuberto site is doing. However I am getting in an awful mess with the scroll event firing an animation on all the slides. I'm not particularly competent with vanilla javascript but would like to attempt this with or without jQuery. I have tried pagepiling.js and fullpage.js but this doesn't achieve the effect I'm looking for. I could really do with a a resolution I can go to my client with, or at least a direction I could go in.

  9. I have created a sliding portfolio gallery type of page and having the hardest time getting safari in particular to render smooth animations and scrollto's. I originally was using scrollmagic and tweenmax which was extremely choppy and could not be used, I re-wrote the page to use only Tweenmax and the ScrollToPlugin, it's much better now, but when I have the images visible, the page is still a bit choppy. I am wondering if there is anything I can do to up the performance. Link: http://melissamorgandesign.com/portfolio Here are the tweens that are going on, the trouble seems to be scaling the div/bgimage while scrolling with scrollto. Going horizontal also adds a wrinkle. TweenMax.to(window, 1.5, {scrollTo:{x:$("#div" + section).offset().left - 30}}); TweenMax.to("#div" + section, 1, {width:"60vw"}); TweenMax.to("#div" + section + " .subsection1", 0.2, {height:" 30vh", delay:0}); TweenMax.to("#div" + section + " .subsection2", 0.2, {height:" calc(70vh - 3.5vw)", delay:0}); TweenMax.to("#div" + section + " .subsection1 h2", 0.5, {fontSize: "48px",autoRound: true, delay:1}); TweenMax.to("#div" + section + " .subsection1 .portfolio-description", 0.5, {autoAlpha: 1, display:'block', delay:1}); TweenMax.to("#div" + section + " .next-jump", 0.5, {autoAlpha: 0, delay:.1}); Any thoughts for smoothing this out?
  10. I'm trying to test out a scroll hijacking method I saw on http://www.adidas.com/us/climazone. On that page, they have a fixed position container with everything in it absolutely positioned and on page scroll they translate3d the elements up -Y scroll position which I can do but they key ingredient they add is easing to that scroll tracking. So as you scroll the elements follow "recreating the scroll effect" but upon release slowly ease into their final place which is the end Y scroll position. I've found this StackOverflow question, https://stackoverflow.com/questions/25056769/how-to-add-easing-to-parallax-movement, where it talks about javascript easing mixed with parallax, however, I can't seem to figure out how to apply it to what I'm doing or what I want my end result to be. I also found this JSFiddle where it adds easing based on mouse movement that I thought might be helpful to use pieces from for easing, http://jsfiddle.net/74mnpgs7/4/. I've added a link to my current CodePen example with my starting point, any help achieving/deconstructing what Adidas Climazone is doing to add easing to their scrollY transforms would be eternally grateful! Another demo I did on JSFiddle is here: https://jsfiddle.net/416ne38h/5/ Bonus if I can use GSAP for this!

    GSAP 1.20.0 Released

    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. Here are some of the highlights of the GSAP 1.20.0 release... yoyoEase Now you can specify an ease for the yoyo (backwards) portion of a repeating TweenMax animation. Set it to a specific ease like yoyoEase:Power2.easeOut or to flip the existing ease, use the shortcut yoyoEase:true. TweenMax is smart enough to automatically set yoyo:true if you define a yoyoEase, so there's less code for you to write. Score! Animate CSS Variables (custom properties) See the Pen CSS Variables Demo by GreenSock (@GreenSock) on CodePen. Emoji support in TextPlugin 'Nuf said. ...and more There are quite a few little improvements and bug fixes as well, which are listed in the changelog at the github repository. Download GSAP today. Happy tweening!
  12. Hi everybody, first time posting here. I've created this example on CodePen to loop a certain part of an animation consisting two frames. I did this by declaring two variables as two separate timelines (TimelineLite and TimelineMax), and then called the function to replay the second frame only. You can take a look at how I wrote this by referring to the CodePen link. I'm still learning both GreenSock and JavaScript, and I feel I've come a long way, but I'd like to know is there a better way to code this without using multiple timelines? Even though I'm satisfied with how the code works, I'm open to feedback if there is a neater way to write this code.
  13. Hi, I want to create a line on top of the frame i.e. the line should start from the center and grow simultaneously towards the side. Have given the sample link (this is in TimeLineLite): I want to add the above code to the following banner (have attached the files as well): The problem that I am facing is how to add this to "TimeLineMax" and the line should start/grow along with the word that eases in the screen. Thanks sample.zip
  14. I have an image: and I want to fill the missing part of it. The best way I found was to convert the missing part of the image to SVG and then start filling the missing part using tweenmax. For reference, I have added the animation for filling the svg but it is not animating like what I need i.e. it is increasing from center point. I need to blend the animation like the image missing area is filling from one end. I can change the way of animating if there is any other way we can fill the missing part of the image? I have also tried other solution of fill mode but smooth transition is not happening in it.
  15. How can I make a text float in like a wave from left to right. I am able to get the text into the frame normally but not like a wave form. Is there a way of doing it?
  16. Hi, Does anyone know why I get an unrecoverable syntax error in JSHint? Below is a script that I have tweaked. The original version was animated. $(document).ready(function(){ $.ajax({ url: "http://s1.adform.net/Banners/Elements/Templates/14036/8970.xml", type: "GET", dataType: "xml", success: function (xml) { $(xml).find("Group[name=9]").each(function () { var belopp = $(this).find("TextVar[name=summa]").attr("value"); belopp = belopp.substring(0, belopp.length-3); $(".jackpot").html('<h3>Just nu '+belopp+'</h3>'); }); } }); }); _________________________________________ The original version $(document).ready(function(){ $.ajax({ url: "http://s1.adform.net/Banners/Elements/Templates/14036/8970.xml", type: "GET", dataType: "xml", success: function (xml) { $(xml).find("Group[name=9]").each(function () { var belopp = $(this).find("TextVar[name=summa]").attr("value"); belopp = belopp.substring(0, belopp.length-3); $(".jackpot").html('<h3>Drömvinsten är just nu <br /> '+belopp+'</h3>'); var txt = $(".txt"); var txtIndex = -1; var playAnimation = 0; function playAgain() { if (playAnimation <= 4) { showNextTxt(); } else { ++txtIndex; $(".endframe").show(); $(".jackpot").hide(); } } function showNextTxt() { ++txtIndex; ++playAnimation; txt.eq(txtIndex % txt.length).fadeIn(200).delay(3000).fadeOut(300, playAgain); } showNextTxt(); }); } }); }); Best, A
  17. Hi there, I'm using TimelineMax and getting some great results. I'm getting quite proficient with using the Timeline to animate various elements on the page. I've found a script called Typed.js that I've been able to run independently of the Timeline perfectly but I'm unsure of how to get it to play within the timeline? I know there are some callback features but my Javascript isn't great! http://www.mattboldt.com/demos/typed-js/
  18. Hi all, I have been stuck because of this click function I want to work. Basically what I want to achieve is if you hover on the item the animation wil start and when unhover the animation wil reverse, this happens to work really good. The part i'm having problems with is the click function. if the user click on the button the div that is related to the button will be shown. Right now if the button is clicked the div will hide or not being shown. I think the reason for the related div not being shown is because of the Gsap animation. I could help some advice for keeping me in the good direction how I could make this work. see my codepen
  19. Hi! I would like to know if there's a way to animate a HTML video. What I would like to do is to add a link to another page on the video, but that link should appear just for a few seconds. For example, the video starts with no animations. Then on second 12, the link appears for 5 seconds and disappears again. I'm thinking of using the video currentTime like this codepen I created: https://codepen.io/sonder15478/pen/Ppeyry Any ideas of how to do it?
  20. I've recently got lucky with an answer from PointC in another thread, and now having spent a few hours researching without luck on another matter, I guess I'll try my luck again. The problem: I have 30 points, each with a X and Y value (DIV's with a Top and Left setting), placed around a map of 1536x1080px. A user can select any of these points, and when that happens, a line should be drawn (animated in) from one point, to the selected one. This seems really straight forward, and to some extend I have managed to do that, with canvas drawing (p5.js), but it turns out extremely unsharp, and seems to be way to complicated, for what it should do, I've even tried just creating a DIV, and animating on it's width, thereby faking a line. I'm assuming maybe the GSAP SVG animation tools can solve this, but had no luck finding it, it's all about pre made SVG files from illustrator, which then are masked in animations, I can't do that, seeing as I have too many points, and never know how many new ones will be created. Any good solutions to this? It seems to simple, to be this complicated :S / Chris
  21. Hey I'm currently working on a touchscreen which let's say for simplicity sake, just has a fullscreen bitmap image, the image is of a book and I wan't to be able to zoom into certain parts of this old book. Around this bitmap of the book, I've placed invisible DIV's to click on, when clicked, I would like the entire bitmap, to center the invisible box, by scaling up the entire bitmap. Basicly like the Zoomooz.js library, but I just know there must be a way to do it with GSAP ................. ................. . . . . . . Result should be: . X . With the "invisible" dom element zoomed in, but by using the viewBox. . X . . . ................. .................

  22. Hi all, Currently I'm testing a website on which I use some GSAP animations. One of this animations causes a error in Firefox (v51 run a Macbook Pro retina). This is the code that causes the error: this.tl .set(this.modalBackground, { display: "block", className: "+=" + this.modalBackgroundModClass }) The classname line causes the following error in Firefox: TypeError: this.ownerSVGElement is null This code does work on all other devices and browsers on which I've tested on. I also can make it work by adding the class like this: this.tl .set(this.modalBackground, { display: "block", onComplete: function () { this.modalBackground.classList.add(this.modalBackgroundModClass); }.bind(this) }) But I would like to use the className way. Any idea on what is going wrong? Thanks in advance.
  23. OK, so I've properly enqueued TweenMax.min.js in my Wordpress install, in my child theme's functions.php file. It's loaded, as a check of the page shows. Just to make sure it's working, I added this test code to a page's footer code: <script type="text/javascript"> var blinkText = document.getElementsByClassName("blinking"); function blink() { TweenMax.to(blinkText, 0.3, { autoAlpha: 0, delay: 0.3, onComplete: function() { TweenMax.to(blinkText, 0.3, { autoAlpha: 1, delay: 0.3, onComplete: blink }); } }); } blink(); </script> When this page loads, the text doesn't blink and the DOM inspector shows an error, reporting "Uncaught ReferenceError: TweenMax is not defined." I don't have much JS experience, but obviously I've missed something simple, and obvious. Can someone help me out here? TIA! SOLVED: Ach, what a pain. It was just a case of script loading and timing. I changed the example code to what I pasted in below, and it works fine in WP, via the OH Add Script Header Footer plug. This plug makes it simple to add things like GSAP scripts on a per-page basis without having to create separate files in the WP child theme. <script type='text/javascript'> // wait until DOM is ready document.addEventListener("DOMContentLoaded", function(event) { // wait until window is loaded (images, stylesheets, JS, and links) window.onload = function() { //fade out and set visibility:hidden TweenMax.to(blinking, 2, {autoAlpha:0}); //in 2 seconds, fade back in with visibility:visible TweenMax.to(blinking, 2, {autoAlpha:1, delay:2}); }; }); </script>
  24. Hi! I have a HTML5 banner advertisement that I'd like to automatically replay the animation on a loop. Is this possible? I have attached the HTML5 banner advertisement source files. Please let me know how to accomplish this. Thank you for your help! 120x600_v2.zip

    Draw Svg polygon

    Hello! I am trying to make an animated SVG of a complex map. I have over 120 elements in my animation. Most of these are paths but some of them are also polygons (circular). Here's a CodePen: http://codepen.io/i76/pen/vgwKKX I am a JavaScript novice. I searched this forum and found a script (in Carl's post) which allows me to draw a path- var orig1 = document.querySelector('#lineAB'); var obj1 = {length:0, pathLength:orig1.getTotalLength()}; orig1.style.stroke = '#f60'; var t1 = TweenMax.to(obj1, 10, {length:obj1.pathLength, onUpdate:drawLine1, ease:Linear.easeNone}) function drawLine1() { orig1.style.strokeDasharray = [obj1.length,obj1.pathLength].join(' '); } However, this does not work with polygons. My guess is that there is not built-in polygon.Length object in JS. I have found this function on another forum that would measure the length of a polygon but I am not sure how to implement it- getPolygonLength:function(el){ var points = el.attr('points'); points = points.split(" "); var x1 = null, x2, y1 = null, y2 , lineLength = 0, x3, y3; for(var i = 0; i < points.length; i++){ var coords = points[i].split(","); if(x1 == null && y1 == null){ if(/(\r\n|\n|\r)/gm.test(coords[0])){ coords[0] = coords[0].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[0].replace(/\s+/g,""); } if(/(\r\n|\n|\r)/gm.test(coords[1])){ coords[0] = coords[1].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[1].replace(/\s+/g,""); } x1 = coords[0]; y1 = coords[1]; x3 = coords[0]; y3 = coords[1]; }else{ if(coords[0] != "" && coords[1] != ""){ if(/(\r\n|\n|\r)/gm.test(coords[0])){ coords[0] = coords[0].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[0].replace(/\s+/g,""); } if(/(\r\n|\n|\r)/gm.test(coords[1])){ coords[0] = coords[1].replace(/(\r\n|\n|\r)/gm,""); coords[0] = coords[1].replace(/\s+/g,""); } x2 = coords[0]; y2 = coords[1]; lineLength += Math.sqrt(Math.pow((x2-x1), 2)+Math.pow((y2-y1),2)); x1 = x2; y1 = y2; if(i == points.length-2){ lineLength += Math.sqrt(Math.pow((x3-x1), 2)+Math.pow((y3-y1),2)); } } } } return lineLength; } If it doesn't take very long would anyone be able to include the above function into the snippet above so I have a way of animating the polygons as well? Many thanks in advance!
