So, I'm creating an Image Gallery. Clicking on buttons calls the "change_section" function, passing it the hires image id. I want to fade out the current image, load the new image, than fade it on the screen. But, for some reason when it losing track of the "this.hires" array that contains the image url, width, height and id. I think it's calling an undefined "Gallery" javascript object. Any insight would be appreciated. Gallery.prototype.change_section = function(_id) { this.new_section = _id; //// Started with TweenMax.to(this, .5, {hires_alpha:0, overwrite:2, onUpdate:reDrawMain, onComplete:this.check_hires}); ///I've tried this var obj = this; TweenMax.to(obj, .5, {hires_alpha:0, overwrite:2, onUpdate:reDrawMain, onComplete:obj.check_hires}); /// Calling just this works, and still sees the "this.hires" array in the Gallery object. So, I don't think it's my logic, but rather I'm not referencing the right javascript object with the onComplete call. this.check_hires(); }; Gallery.prototype.check_hires = function() { var i; for (i=0;i<this.hires.length;i++) { if(this.hires[i].id == this.new_section) { if(!this.hires[i].loaded && !this.hires[i].loading) { this.load_hires(); } else { this.active_section = this.new_section; this.open_hires(); } } } }; The code below is for reference. Maybe I have conflicting calls to TweenMax or something. Gallery.prototype.open_hires = function() { TweenLite.to(this, .5, {delay:.5, hires_alpha:1, overwrite:2, onUpdate:reDrawMain}); }; Gallery.prototype.load_hires = function() { trace("Gallery load_img") var obj = this; var i; var s; for (i=0;i<this.hires.length;i++) { if(this.hires[i].id == this.new_section) { var hires_img = new Image(); this.hires[i].obj = hires_img; hires_img.id = this.hires[i].id; hires_img.onload = function () { obj.hires_loaded(this.id); } this.hires[i].loading = true; hires_img.src = this.hires[i].img; } } }; Gallery.prototype.hires_loaded = function(_id) { var i; for (i=0;i<this.hires.length;i++) { if(this.hires[i].id == _id) { this.hires[i].loaded = true; this.active_section = _id; this.open_hires(); } } };

I am wondering if there is a way to tween essentially the same way as you would using the DynamicPropsPlugin in As3. something like this from your documentation but in javascript. TweenLite.to(myDiv, 3, {dynamicProps:{x:getMouseX, y:getMouseY}}); Secondly would it then be possible (without using a function like above) to reference a dynamic value of another element. I would want the Tween to update if "anotherdiv.width" changed during the course of the animation. Maybe the only solution is using whatever answer there is for my first question? TweenLite.to(div, 1.5, {width:anotherdiv.width}); thanks -ross

I'm still getting used to the Javascript world since unfortunately as flash web developer I have to make the gradual shift because of handheld devices. My question is how to create a preloader in Javascript using maybe Greensock plugin. I'm used to something like this in Flash function LoadingImageImage1(event:ProgressEvent) { var percent:Number = Math.round( ((event.bytesLoaded)*100)/(event.bytesTotal) ); ImageLoaderFeedback.scaleX = (percent/100); if( percent == 100) { TweenMax.to(ImageLoader2, 1, {delay:0.8,autoAlpha:0, ease:Cubic.easeOut}); } } Can anybody point me to the right direction of what I need to do. Thanks Cinoklu

Hi, I was implementing a tween based on CSS3's background-size today. That would map to "backgroundSize" as defined in CSSPlugin.js. However, the tween doesn't work in the latest Firefox. While it works perfectly in the latest Chrome. I digged down until I found about this condition in _parsePosition function in CSSPlugin.js: _parsePosition = function(v, o) { if (v == null || v === "" || v === "auto") { v = "0 0"; } Debugging this, I found that 'v' was passed in as 'auto' in Chrome. But it was passed in as 'auto auto' instead in Firefox. Since 'v' was not changed to '0 0' this leads to parsing problem resulting in 'NaN' in o.ox. And thus the effect doesn't work. My TweenMax code looks like something along these lines: controller.addTween( chart.offset().top, TweenMax.fromTo($('.bub', chart), .25, {css:{opacity:0, 'letter-spacing':'30px', backgroundSize:'0% 0%'}, immediateRender:true, ease:Quad.easeInOut}, {css:{opacity:1, 'letter-spacing':'0px', backgroundSize:'100% 100%'}, ease:Quad.easeInOut} ), 0, -350 ); I patched CSSPlugin.js locally so that it now handles 'auto auto' case. The backgroundSize transition now works correctly on my machine. if (v == null || v === "" || v === "auto" || v === 'auto auto') { v = "0 0"; } Hope this helps. Not sure of any proper channel to report issue for TweenMax? Natthawut

Ok well I know I can tween one object in my array like so: // tween y prop of ball.position object TweenMax.to(balls[0].position, 1, {y: 50}); I am trying to tween all of my objects in an array like so. // try to tween all balls y prop of position object - DOESN'T WORK TweenMax.to(balls, 1, {position:{y: 50}}); The reason I thought this would work is because it is similar to css syntax on the site: //tweens multiple objects simultaneously TweenLite.to([e1, e2, e3], 1, {css:{autoAlpha:0}}); What is the syntax for this, I don't want to store "ball.position" in the array, just the ball. Thanks Neil

Flash was once a passion. It still feels more advanced than HTML/Javascript for interactive projects due to years of developments added to it. Lately though I've become very interested in the possibilities of JavaScript combined with advancements in libraries like GreensockJS. So this is an experiment, and a source of inspiration of sorts. Also I thought it would be great to have a single topic where everyone can share your examples! I know some of you have a lot of things you've created lately or are in the works. There's probably some really cool things out there! I'd personally like to see what things GreensockJS is capable of reproducing from what we were used to seeing in Flash advertisements, and other animated/interactive Web "creations". Needless to say my GreensockJS samples aren't quite the best yet. I've just been experimenting enough lately to see just what it can do. Though still, I'll start by sharing a few basic ad banner samples made with Greensock JS TweenLite. So check it out here. Everything on the page is HTML/JavaScript/CSS/GreensockJS. Note it might be a little slow loading (not due to Greensock in any way). Just refresh to see the full animations again. So again if you've made something original and creative in Greensock JS, share it here for others to see. Enlighten us all on the possibilities of Greensock JS!

Hey so i'm not sure if this is a greensock bug or a browser bug or me just pushing the limits too much, but what i have noticed on a couple projects i've started lately is that where i may have a bunch of tweens going on successfully in Chrome or Firefox, that when i test in Safari or on my iPhone, the animations dont seem to fully update visually. if i resize the window or anything like that, the screen corrects itself. where i've run into it, the problem doen'st happen if only 1 or two things are tweening at once, but if a more than a handful are tweening at once, it seems that the browser cant keep up or something. if you zoom in or out or rotate the screen or something to get the browser to react, the end of the animation will rectify itself after its been messed up. even with the window resize listener turned off. you can check out one project currently in progress where you can view this. to see them problem, in safari or on iphone open the link, then click between "bird" and "big bang". you will see that the divs and the nav elements will linger in Safari and iOS, yet not in Firefox or Chrome. if you step across the nav one at a time, (big bang, liquid, snakes, globe, wedges, candle, bird...) then it tweens fine in all browsers. http://danehansen.com/temp/gs

Hi Thanks in advance for any responses. I am trying to figure out what is the best way to load a large image sequence (300 images representing a 3d movie) and control it using TimelineMax or simply staggerTo. I used to do these things super easy with Loadermax (loading the image list from XML) and tweening it. I have no idea how to do generate this array of images using javascript. Please help. Fernando.

Hi all, I'm in my first JS GSAP project and I've just discovered what seems to be a long standing issue with Javascript: fading in elements after the page has loaded, causing a "flicker" before they're able to start in their opacity:0; state. I have my elements starting at opacity:0; in my CSS and in my JS, I'm using TweenMax.from to {css:{autoAlpha:0}. What's the best practice here to prevent that flicker? Any good workarounds specifically using GSAP correctly for a simple fade in? Thanks as always!

So i am completely new to greensock and javascript animations in general and relatively new to javascript (although I know other web languages HTML, CSS, PHP, MYSQL) I have a website that works like a single page website where the navigation just goes to div ID's and I use a basic smooth scroll to the get there. My navigation is fixed to the top of the page. So in the navigation bar that is fixed to the top of the page, I have this little tag that I would like to drop down / expand when you are on a specific div and then shrink back up when you go away from that div If I am not making sense, here are some screen shots: The "home page" which is basically the first <div> in the stack http://cl.ly/33371i3B2q0V0D203T1u the "about page" which is the third <div> in the stack http://cl.ly/013H3f3c1i093C152J32

Hi Jack, Just wondering if you had any plans on creating a JS equivalent to TransformManager in addition to the newly released Tween library. Thanks!

Hi all, I've been watching a few tutorials around tweening with the new GSAP for javascript but I'm still wondering how I would go about tweening text. I see that Carl has animated text in his video here: http://www.snorkl.tv...red-javascript/ so I'm wondering if those are just images or css text elements? Text animation in Flash through GS was a breeze which makes me think I'm not approaching the same goal (but in javascript) the right way. Essentially, I have a banner with graphic and text elements that I'd like to animate in a sequence. Are there any tutorials out there for this now? Carl, I know you're probably working on one so if you have time for some insight, I'd appreciate it! thanks!

Hi, I wonder if we will have bezier support in javascript version soon? I had a great success with greensock and easelJs together, I can almost 100% duplicate what I have done with actionscript 3 before, apart from bezier curve animation...

So has anyone been using Adobe Edge? Ok, so I really thought about whether this should be shared or not (and promoting some possibly bad Greensock usage/code in the process - thus sort of being detrimental to the point of Greensock JS in the first place). But hey, it's still using Greensock JS after all.. This tutorial shows how to import and use Greensock JS within Adobe Edge: http://chrisgannon.w...ipt-adobe-edge/ Adobe Edge is the new HTML/jQuery based animation program, and it may SOME DAY end up being the equivalent to the Flash IDE. That's if Adobe can figure out a way - not just to make cool animations - but also to create better, re-usable code behind the pretty scenes (so that other people can actually edit it if they're developers and not just animators). If Adobe succeeds, then this method of being able to import Greensock JS into Edge might be like you can do to import Greensock libraries in Flash and use it in the program. Edge is only still in Beta and has a long way to go before it's ready to do any professional projects.. because the size of the files it creates and organization of code is not great, let's just say. As such, think of this tutorial, and Edge as only a fun thing to play around in for now! At least now we know Greensock JS is usable in it!

Hi All, I have been playing around on the latest version of Adobe muse since the weekend, and its shaping up to be a pretty rad tool. My only problem is, I want to use my shiny new javascript version of the ever incredible Greensock platform - but cannot seem to get it to work.. I have tried everything I can think of with no result, I was wondering if anyone else had any luck? Thanks,

I am getting the error "invalid argument" from TweenMax.min.js line 16 in IE9 simulating IE8. Im trying to test my TweenLite code in IE8 &> but cant get past this error. Any help would be appreciated. -----update----- changed from TweenMax to TweenLite + CSSPlugin but now the error is popping up in the CSSPlugin script, line 14, character 12005. D
