  1. Hey everyone, I recently put together a nifty little site for a local event in town and (of course) I utilized Greensock in my project. I took a demo that I had found and tweaked it so I could create the snowfall effect seen in the hero/background. However, I've noticed that it seems like its slow (performance wise) on certain devices and its gotten me thinking that maybe I can optimized the performance to insure a steady 60fps framerate (as consistently as possible). The codepen URL I provided shows the original fork example I created. http://codepen.io/iansvo/
  2. Hello again Looking at the documentation and having used it a lot in the past days, it seems to me that TimelineLite can almost always be used. Since from your own example it can be written in two ways:= //add another tween at the end of the timeline (makes sequencing easy) tl.add( TweenLite.to(element, 0.5, {opacity:0}) ); //append a tween using the convenience method (shorter syntax) and offset it by 0.5 seconds tl.to(element, 1, {rotation:30}, "+=0.5"); The second way above is very similar to how you would write if using TweenLite.to( etc...) So I wonder if there's any good reaso
  3. Hi, I am wondering what's the relationship between stagger's duration and stagger's staggerDuration. Looking at this code: TweenMax.staggerTo([mc1, mc2, mc3], 1, {x:100, y:200}, 0.25}). The time duration is 1 but there are 3 elements to stagger. mc1 = 0.25, mc2 = 0.25 + 0.25 mc3 = 0.25 + 0.25 + 0.25 1 - 0.75 = 0.25 (What happen to this extra 0.25?) - Is the duration the total duration for the whole stagger code (mc1, mc2 and mc3 combined?) And the stagger duration will modulate to fit within the whole duration? Thanks, Venn.
  4. Hi! Think I found a bug of some sort that if I add a class name using TweenMax and my tweening object has already a classname that contains the same word it removes. Example: Want to add a class by name: "hover" My div has classes: <div class="btn animate-hover color-green">My Button</div> The result will be: <div class="btn animate- color-green hover">My Button</div> It shouldnt behave like that am I right? If using underscore it works: <div class="btn animate_hover color-green hover">My Button</div> Possible to solve this?
  5. I'm new to GreenSock, I have 2 objects that have the same ID. I've added an opacity but it only fades in one of the objects, what am I doing wrong. I've searched a lot and can't find a solution. Here is my code, I have 2 headshots I want to fade in but only one headshot fades in, nothing happens to the other. window.onload = function(){ var headshot = document.getElementById("headshot"); TweenLite.to(headshot, 0, {autoAlpha:0}); TweenLite.to(headshot, 2, {autoAlpha:1, delay:2}); }
  6. Hi, I have been trying to create an image carousel for a website, I found Greensock out of a recommendation because jQuery animations aren't as fluid, I looked at the beginner tutorials from Petr and also followed a tutorial he has on youtube, I have been having problems making the images rotate as shown in my codepen. Can someone help me please?
  7. Hey everyone, Image you have a cartoony chess game. And you're sliding the queen from one end of the board to the other. I want to add a teetering effect, with the piece pivots on it's base a bit to begin it's slide, and then teeters in the other direction when it ends. I have the pivot centre at the bottom center, but I can't seem to find an elegant way to pivot back and forth. So what I've done is: var maxTilt:Number = 10; // degrees var slide:TimelineLite = new TimelineLite( { autoDispose:true } ); slide.add(TweenMax.to(obj, DURATION / 4, { rotation: -maxTilt} )); slide.add(Twee
  8. I am testing an animation through Google Chrome which currently is not working. I do not receive an error but the console log reports "invalid pause tween value: true". In general, what does this mean? I searched the forums and did not find any topics on this message so I though I would go ahead and ask. If it helps, below is my code for the tween: var fadeOut = function (el) { var animation = TweenLite.to(el, .75, { autoAlpha : 0, bottom : "-=100px", ease : Linear.easeNone, paused : true }); return animation; };
  9. I have put together a compilation of 11 short videos with quick demos explaining the basics of GSAP API to a complete beginner.

  10. hi all, im trying to create a slide effect for the side nav and just after that a stagger for the `li` but I'm not sure how to get it done. i've tried two separate setTween() and also onComplete but i obviously doing something wrong this the animation plays wrong or not at all. so again, I just want the navbar to slide in when im scrolling to it and immidiatly after i want to `li` (.btns) to animate to var sideNanFrom = { opacity:.3, width:0, ease:Elastic.easeOut, onComplete:sidNavBtnTween } var sideNavTo = { opacity:1, width:130, delay:0.4 }; var btnsFrom = { scale:0, o
  11. I've been meaning to learn GreenSock for some time and have been trying to justify the cost of onsite trainer to management for some time since we are getting asked to do more and more banner work. But as a complete newbie to TweenLite, I am wondering if it would be a good solution to a problem we have right now. I am drawing an arc on a canvas and am trying to tween just the endAngle var. Since this isn't an attribute of the canvas itself, but a var within it, I'm not sure if TweenLite is what I am looking for. I've linked to a very quickly thrown together example. Any help
  12. Stumped on this. I would like to use the attr plugin to do a simple animation for my banners, basically just have an image animate in from the side or top. This page makes it seem like I could use the attr plugin to animate the x, y coordinates of an element. I can get the heigh and width animation working as long as I use a table, but can't figure out how to get the x and y working. https://greensock.com/AttrPlugin My html and scripts are attached.

  13. This code successfully brightens, then dims image brightness (via the css filter attribute): TweenLite.to($(this).children('img'), 0.1, { css: { '-webkit-filter': 'brightness(1.75)' }); TweenLite.to($(this).children('img'), 1.5, { css: { '-webkit-filter': 'brightness(1.21)' }, delay: 0.15 }); However, I'd like to tween the brightness level to get a smooth transition (rather than the current stepped/chunk method that this code produces). Is there a GreenSock solution/approach to tweening at this level?
  14. Hello all. I have a container as below: .section-fixed{ position:fixed; width:0px; height:0px; top:-280px; right:-280px; overflow:hidden; -webkit-border-radius:50%; -moz-border-radius:50%; border-radius:50%; background:transparent; opacity:0; z-index:10; } which there is a few items within it: .item-f{ text-decoration:none; top:calc(50% - 15px); left:calc(50% - 15px); position:absolute; border-radius:50%; width:30px; height:30px; text-align:center; color:black; font-size:25px; cursor:pointer; } <section class="section-fixed"> <div class="main-menu-f"> <div id="HomeButt
  15. I am looking for a way to use the staggerTo, etc. methods on TweenLite, but am not sure what plugin file to include. Plz help
  16. Hi there! I have many shapes in EaselJS -not spritesheet, only shapes- (shape_1, shape_2, ..., shape_n) which are different frames of the same object and I want to animate them with TweenLite to display all the frames (1,2,3,4,...), like an animated movieclip in flash. I have seen that with CreateJS TweenJS works this code: this.timeline.addTween(createjs.Tween.get({}).to({state:[{t:this.shape0}]}).to({state:[{t:this.shape1}]},1).to({state:[{t:this.shape2}]},1).to({state:[{t:this.shape3}]},1).to({state:[{t:this.shape4}]},1).wait(1)); to display sequencially all the shapes...
  17. I have created a rss feed ticker in as3 with TweenLite. Flash FPS is 24. When I run this, the scroll animation is not smooth. If I change the FPS to 120, it appears very smooth. There are many different movieclips on stage which may have their own animation, so I can not change the Flash FPS. Is there any way available in TweenLite where I can change FPS for this movie clip only?
  18. Can Greensock TweenLite/TweenMax globals be obtained when using the library as CommonJS module? E.g. easing functions that are available as window.com.greensock.easing, like let Power4 = require('./TweenMax')... I feel myself 10 years younger when I look at all these globals. I look at the source code and see that the only export is TweenMax constructor. Can it be done somehow without resorting to globals at all?
  19. Hello, my problem is, I have some styles inline in a element: <div id="myDiv" style="display: inline-block; position: relative;">Some Text</div> And I'm trying to animate this div, like this: TweenMax.to($('#myDiv'), 0.6, { parseTransform: true, alpha: 1, left: 0, top: 0, scale: 1, ease: 'easeOutBack' }); How can I use TweenMax without removing my inline styles? Thanks.
  20. Hello! I am trying to work out something where there's two side panels that can be collapsed to make the middle panel bigger. I have it 75% of the way there -- the only thing that doesn't work is that if you try to collapse both side panels, the middle doesn't go to it's full size (just stays at it's 3/4ths size as if only one panel is closed). I've done everything I could to get the codepen to work but even though it has everything in it that works outside of codepen, it won't actually animate and I can't figure out why, so I uploaded everything to my private server to show that it does w
  21. Hello, at the moment I have a div that rotates infinite with normal css animations. But I want to do it with Greensock, because i want the animation to be more responsive depending on what I click. The idea is that I want the div to start rotating after clicking a button. It start slow and builds up speed. After 1 Second it's on full speed and keeps rotating until I press the button again. Then it should decrease the rotation till it stops. Could somebody point me in a direction? I would prefer to use tweenLite if that is possible.
  22. Hey there, I am pretty sure, someone asked this before and it's explained somewhere. I just don't find it. In the provided codepen, please check the JS imports. It's only TweenLite. Why doesn't it work like this? I tried importing TimelineMax only, too, then added a var tl = new TimelineMax(); Nope... How can I make good use of the smaller libs? Thanks guys, Laser
  23. Hello! I am building a timeline visualizer, that you can easily connect with any timelines you've made with gsap. The idea is to represent the timeline visually, and let the user scrub through it. It's easy to visualize the labels, since there is a _labels property on each timelinelite instance. However, what I would like to know is: Is there any good way to get a reference to all tweens within a timeline, and all function calls? I'd like to know the time and duration of all tweens within a timeline so I can represent them visually, and also the time and name of all function calls within
  24. I tried use TweenLite in this pen: http://codepen.io/lagden/pen/QjQbwp?editors=001 and nothing happens! I would like to use TweenLite, but I don't know which feature is missing for it works!! TweenMax is very heavy for it! This is my current code! It is using TweenMax and it's working. TweenMax.fromTo(circle, duration, { x, y, scale: 0, opacity: 1, transformOrigin: '50% 50%' }, { scale: 10, opacity: 0 });
  25. Hi all! I have some strange error with ie 11 (may be earlier versions too). Here is a simple example of my code: var gfx_obj = {}; gfx_obj.r1 = 1; gfx_obj.r2 = 1; gfx_obj.r3 = 1; gfx_obj.r4 = 1; function appearGFX(num) { TweenLite.to(gfx_obj, 1.2, {["r"+ num]:5, ease: Power3.easeOut}); } appearGFX(1); So this gives me error in IE only (all other modern browsers is OK). Screenshot of error is attached. Any thoughts how to fix it?
