    GSAP 3.7 Released

    GSAP 3.7 is here! Here are some of our favorite bits... Percentage based position parameter options for timelines Better support for SVG elements with Flip plugin. Easily scope animations to your components! New scoped selector - gsap.utils.selector() Optional scope parameter added to gsap.utils.toArray() Percentage based position parameter. The position parameter is small but mighty. It's the key to building sequenced animations with precise control over timings, and now it's even more powerful! This update gives us the ability to position animations using percentage values - either relative to the previous tween or animation, or relative to the duration of the animation being inserted. The percent is based on the totalDuration(), so repeats, yoyos and staggers will be factored in. This is such an exciting one because it allows us to tweak durations without affecting positioning! Say we wanted to overlap a tween by half of it's own duration. Until now we would do a little mental math, divide the duration in half and add it to the position parameter as a relative position. tl.to(..., {duration: 2}, "-=1"); But if we were to change the duration, we would also have to update the position parameter Now, with the addition of percentages, we can do this instead: // overlap by half of the inserted tweens duration, -1s: tl.to(..., {duration: 2}, "-=50%"); Alternately, we can position a tween or timeline in relation to the most recently-added animation. tl.to(".other", {x: 100, duration: 2}); // insert 25% of the way through the most recently added animation. // In this case - 0.5s into the 2s duration. tl.to(".class", {x: 100}, "<25%"); Or at a percentage from the end of the most recently-added animation, like ">-25%". >-25% is equivalent to <75% tl.to(".other", {x: 100, duration: 2}); // insert 25% of the way from the end of the most recently added animation. // In this case - 0.5s from the end of the 2s duration. tl.to(".class", {x: 100}, ">-25%"); As '+=' and '-=' are always based on the inserting animations total duration, we can even use a pointer to reference the starting point of the previous tween, whilst using the inserting tweens duration as the percentage offset. tl.to(".other", {x: 100, duration: 2}); // insert 50% of the inserting tweens duration from the beginning of the most recently added animation. // In this case - 0.5s from the start of the previous tween. tl.to(".class", {x: 100, duration: 1},"<+=50%"); Powerful stuff! If you want to dig in a bit more, here's a video explainer and some demos to play around with. You'll be a positioning pro in no time! Check it out in action in these demos. Interactive Position Parameter Demo Better support for SVG elements with Flip plugin. Flip plugin has been extended with better support for SVG elements. SVG already has a great coordinate system to work within - but we think this could assist transitions in live data-vis or when animating between states in generative SVG. We'd love to see what you do with this so don't forget to share your demos with us! In the meantime, here's a simple example Easily scope your animations Modern front end dev is all about encapsulated components, but scoping animations to each individual component can be tricky. React devs, for example, often find themselves in "ref Hell" creating a ref for each and every element they want to animate. Wouldn't it be nice to just use classes and selector text that's limited to your component instance? gsap.utils.selector() With gsap.utils.selector() you can grab descendant elements from the selected element. It's similar to jQuery.find() This is great for components because you can create a scoped selector for that component's main container element and then use that to select descendants. It's similar to calling .querySelectorAll() on that element – rather than on the document – except with a few added benefits: It returns an Array rather than a NodeList, so you get access to convenient array methods like .filter() and .map(). You can pass a React ref or Angular ElementRef to gsap.utils.selector(). Then when you use the resulting function, it will automatically check for the .current/.nativeElement in case it was re-rendered since creation. // Vanilla let q = gsap.utils.selector(myElement); // or use selector text like ".class" let boxes = q(".box"); // finds only elements with the class "box" that are INSIDE myElement // or plug directly into animations gsap.to(q(".circle"), {x: 100}); // React let el = useRef(); let q = gsap.utils.selector(el); useEffect(() => { // uses el.current.querySelectorAll() internally gsap.to(q(".box"), {x: 100}); }, []); // Angular @Component({ ... }) class MyComponent implements OnInit { constructor(public el: ElementRef) { this.q = gsap.utils.selector(el); } ngOnInit() { // uses this.el.nativeElement.querySelectorAll() internally gsap.to(this.q(".box"), { x: 100 }); } } A common pattern in React is to declare a ref for every element you want to animate, but that can make your code very verbose and hard to read. By using a scoped selector, we only need to use a single ref. Then we can simply select the descendants. gsap.utils.toArray() We've also added an optional, second scope parameter to gsap.utils.toArray() This will find all the descendant elements of myElement with the class of "box": gsap.utils.toArray(".box", myElement) And more... GSAP 3.7 also delivers various bug fixes, so we'd highly recommend installing the latest version today. There are many ways to get GSAP - see the Installation page for all the options (download, NPM, zip, Github, etc.).

  2. Greetings Greensock community I have a "simple" question, which i cannot for the life of me figure out on my own. In Angular, i have several methods in my component, it could be "closeEverything()", normally i call such function with "this.closeEverything()". Now, when i try to call such method in a TweenLite.to onComplete callback, it says undefined function. So far so good. Greensock does not know anything about the Angular scope, and i reckon Angular does now know anything about the Greensock scope. Now from what i have read, i might be able to change the scope Greensock uses in the onCompleteScope property, but i have not been able to make it work. Does anyone have an example, where out-of-scope functions are being called in Tween callbacks? What is it i am missing, i feel like a complete newbie again, trying to implement this otherwise awesome library into my existing Angular application. /Balslev
  3. Hi Is there any way to make a timeline that is inside a function accessible outside of it? I have a short animation sequence used in different places on a site. I'd like to wrap the timeline in a function, but the problem is I'm also using scroll Magic. Thus the setTween method of scrollMagic needs you to pass the name of the tween in as a parameter. I tried using return with the timeline name (as return myAnimation) at the end of the function, but this didn't work. I've set up a simplified example codepen (link given above and minus the scrollMagic) to make it easier to illustrate any solution. I'm thinking there must be a way to make a timeline accessible outside of a function? Any help would be amazing. Emily.
  4. When calling TweenLite.killDelayedCallsTo on a method of an object, all objects with the same prototype will have there delayed calls to that method killed. Cause: When no scope is bound to the method, the method is really the same function object shared by all instances of the prototype. So they will all be killed by 1 call. Solution: Bind your callbacks using .bind(this) or use a closure and place the bound function/closure in a variable. Then, later you can call TweenLite.killDelayedCallsTo on the bound callback. A second argument in TweenLite.killDelayedCallsTo for specifying scope would also be nice, just like with the onCompleteScope etc in TweenLite.to/.from. That would save us a lot of binding and storing functions, and would be in line with the other static TweenLite methods.
  5. Hello, Is it possible to pass $(this) into a timeline so that I can access $(this) as well as the data attributes of an object? In the example pen I'd like to pass data attribute values from buttons into the timeline, ultimately to fade between two images - only after they have each fully loaded. Thanks.
  6. Hello. I am trying to use GSAP with node.js WITHOUT polluting the global scope. I am ussing nw.js (so, I have available the window object) First I do: npm install gsap --save Then in my Tween.js: var gs = window.GreenSockGlobals = {}; require('gsap'); console.log(gs); // logs empty object console.log(window.GreenSockGlobals); // logs empty object console.log(window); // logs the window object, with ALL the GSAP stuff in it console.log(window.TweenLite); // logs tweenlite object I don't want to have all the GSAP stuff in the global scope. I want to have it in a specified object. Thanks.
  7. Hi everyone! Lately i had a discussion with one of my coworkers about this issue: I have object named MyObject with method named launch. On every launch method call, method searches for TweenMax at global scope. Normally i would do: MyObject.launch = function(){ var domName = "#dom-" + String(Math.round(Math.random()*100)); TweenMax.to(domName,1,{x:200}); } Problem begins, when this method fires on every user scroll, which can be A LOT (especially in Firefox). My question is this: Isnt better to create an instance of TweenMax as a property of MyObject like this to reach better performance? MyObject.TweenMax = TweenMax; MyObject.Math = Math; MyObject.launch = function(){ // Fires VERY often var Math = this.Math, TweenMax = this.TweenMax, domName = "#dom-" + String(Math.round(Math.random()*100)); MyObject.TweenMax.to(domName,1,{x:200}); } In this scenario i would completely avoid of any global scope reaches. Please keep in mind performance-friendliness. However i still have a bad feeling, that this is not a good approach, but I dont know why. Any of your comments are deeply appreciated.
  8. I want to animate something (the position of the background image) of a div when the user hovers over (mouseovers) it. There will be several of these divs on a single page. It would be REALLY nice to be able to specify classes, not IDs, of DIVs, when constructing greensock timelines, but as that's impossible I've had a stab at it in this jsfiddle: http://jsfiddle.net/cheolsoo/mp3qes6n/ 1/ why doesn't the (global) value of i get set when the mouseover event fires? I initialized i to 611 but it doesn't change when I mouseover one of the other divs. 2/ (much less critical as I can work around it) my fiddle works (sort of) because I stripped "vid_" away from the div ID and then added it back in the TimelineMax definition. I tried simply passing a variable (e.g. i where i='vid_611' rather than '611') instead of "vid_"+i, but then nothing worked at all. Why not? (Is that a greensock question or a Javascript question? I'm such a moron I'm not even sure.) thanks, eh Ryan
  9. Hi all, I'm doing a front page with 5 animations where one fades away in place of another, and so on, and then it loops. Rather than write one enormous hideous looping timeline I thought I'd make each of the animations a separate timeline and use callbacks to trigger subsequent timelines and JQuery to fade the relevant DIVs in and out. A condensed version of my code is below. The callbacks work great until I get to the last animation (vr_pan5). It fades in the DIVs required to replay the first animation, but then doesn't restart the first animation (vr_pan1). I tried shuffling the order of the timeline declarations in the code. The issue seems to be an inability to play a timeline at the top of the code, after having played a timeline further down. I also tried moving code in and out of the window.load function, but that didn't make a difference either. Sorry for asking what is essentially a Javascript question and not a Greensock question! Also, sorry for not creating a codepen; I figured a glance at my semi-pseudocode would be enough for someone enlightened. Code follows: var vr_pan1, vr_pan2, vr_pan3, vr_pan4, vr_pan5; vr_pan5 = new TimelineMax({paused:true,repeat:0, onComplete:nextAnim, onCompleteParams:["#fg5", "#bg5", "#fg1", "#bg1", vr_pan1]}); vr_pan5 .add("start") //tween some stuff ; vr_pan4 = new TimelineMax({paused:true,repeat:0, onComplete:nextAnim, onCompleteParams:["#fg4", "#bg4", "#fg5", "#bg5", vr_pan5]}); vr_pan4 .add("start") //tween some stuff ; vr_pan3 = new TimelineMax({paused:true,repeat:0, onComplete:nextAnim, onCompleteParams:["#fg3", "#bg3", "#fg4", "#bg4", vr_pan4]}); vr_pan3 .add("start") //tween some stuff ; vr_pan2 = new TimelineMax({paused:true, repeat:0, onComplete:nextAnim, onCompleteParams:["#fg2", "#bg2", "#fg3", "#bg3", vr_pan3]}); vr_pan2 .add("start") //tween some stuff ; vr_pan1 = new TimelineMax({paused:true, repeat:0, onComplete:nextAnim, onCompleteParams:["#fg1", "#bg1", "#fg2", "#bg2", vr_pan2]}); vr_pan1 .add("start") //tween some stuff ; function nextAnim(fadeout_div1, fadeout_div2, fadein_div1, fadein_div2, new_anim) { $(fadeout_div1).fadeOut(); $(fadeout_div2).fadeOut(); $(fadein_div1).fadeIn(); $(fadein_div2).fadeIn(); var o = new_anim; o.restart(); } $( window ).load(function() { vr_pan1.play(); }); Thanks, eh.
  10. Hello, I'm using Draggable with onDragEnd and onDragStart events to perform some tasks. In order to complete the onDragEnd tasks I need some variables defined inside the onDragStart function be visible inside the onDragEnd function. I see that's the purpose of onDragStartScope but it's not very explicit on how actually do that. Can you clarify this a bit more please? Thank you, your help will be appreciated.
  11. hello.. has anyone used the delayedCall() method with scope? I looked in the API but was seeing if anyone had an example they might want to share.. i was trying to pass an element to use for the scope of this in the function, but im probably missing something in how its implemented any help will be highly appreciated, thanks
