The JS api doc's say that the duration of a tween has to be in seconds. Can this be values less then 1s, like 0.6 (600ms), or 2.54 second? I think so, just checking, as I am not completely sure...... Or does it round/truncate the numbers? Thanks

I'm just beginning to get my head wrapped around a project which involves porting some of my Flash applications (built with TweenMax) over to javascript. I'm trying to understand what the best practice is for translating a fixed-coordinate system (Flash) to a flexible / multiple-resolution environment. (HTML). My Flash applications all run at full screen, so in order to simply account for all mobile environments, I assume that one simply creates a "screen sized" DIV set at height/width 100%. But since TweenMax uses a numerical coordinate system, I'm wondering if there's a commonly used approach to translate that to a percentage-based coordinate system? Can TweenMax work with percents instead of fixed coordinates? The examples I've found seem to use multiple CSS definitions for multiple platform types -- although this seems like a real pain -- particularly if the coordinates don't need to be that precise. Or is a % based method inadvisable for some reason?

Hello everybody! I have a problem with the Superscrollorama plugin. I'm a graphic desiner, so I don't understand too much about Javascript. But I'm trying to learn it. I could make an animation with the plugin, but my problem is that I'm doing a responsive website, where each section has a height that fits on the screen. For this reason, I would need to start the animation when the section is displayed, not when I scrolled up to X number of pixels (3000px in this case). I hope I explained the trouble. I'll paste the code that I would like to change, someone can help me? Pleeeeease controller.pin($('#slide5'), 2800, { anim: (new TimelineLite()) .append( TweenMax.fromTo($('#move-1'), .75, {css:{left: 0, top: 0}, immediateRender:true}, {css:{top: 100}} ), -1.5 // offset for better timing )

Hi Greensockers - you will see that my trouble is not Greensock but rather incorporating a two dimension Array to feed back into the TimelineMax tweens that I have set up. I have seen that it's possible to have the Tweens inside the array as it loads and have attempted that as well. I'm fairly sure that my limited programming knowledge hasn't helped me and I apologise for the circuitous methods employed. If anyone has time to plough through all this I would appreciate any help you can provide. Once I have the array loading and feeding I will add some colouration. Many thanks - Trevor Forgot - CodePen working is: http://cdpn.io/mkCJd and non-working is: http://cdpn.io/Abjip http://codepen.io/thorntontf/public/ greensock.html greensock array test.html

Not sure if this is me or not, so I wanted to check it out. I am more or less doing an animation with a sprite map. When trying to change the backgroundPosition in IE8 I get an error. But changing the backgroundPositionX and Y individually is fine. Here is my code: var flame = document.createElement('div'); . . . flame.style.overflow = 'hidden'; flame.style.backgroundImage = 'url("my_files/images/flame.png")'; var tl = new TimelineMax( { repeat:-1 } ); tl.to(flame, 0, { css:{ 'backgroundPositionX':'-5px', 'backgroundPositionY':'-7px' } }, 0); //no error in IE8 tl.to(flame, 0, { css:{ 'backgroundPosition':'-17px -4px' } }, .1); //error in IE8 The error is: SCRIPT5007: Unable to get property 'backgroundPositionX' of undefined or null reference TweenMax.min.js, line 15 character 22204 Please let me know if I'm coding this wrong. Thanks!

Hi, We're using TimelineMax and TweenMax to make a scrollable timeline animation. Everything is going great except when leave the tab open and navigate away to another tab, which causes chrome to (I'm not sure on this one) suspend or slow down timers from 'ticking'. When you navigate back to the tab, we're seeing erratic behavior that will show random pieces of our timeline all stacked up on top of each other (http://screencast.com/t/vC00sJHXCkCT). I've tried to use https://github.com/ai/visibility.js to set the timeline progress to zero whenever a user activates the tab again, but the behavior still exists. Steps to create: 1. go to http://alert-gum.herokuapp.com/ in chrome/firefox 2. scroll down a little bit 3. open a new tab in front of the alert tab and wait for 3 mins 4. go back to the tab and try scrolling. result: items scattered and stacked on top of each other from different points in the timeline. p.s. the issue 'kind of' fixes it's self if you scroll all the way up and all the way down (obviously not satisfactory) Thanks for any help.

I am having some basic trouble getting a div within a div to alpha tween on and off. Basically I'm trying to randomly change the text inside the div (it will be using a pictorial font so the image will change). The text changes, thus the timelineMax is working, but there is no tweening on and off -- no alpha tweening. I'll include the relevant js and css below -- if the full zip is needed, can do, but I'm sure it's something really simple I'm missing. I also noticed that storing the div in a 'global' variable -- grabbing it at the start with jquery -- wasn't working for whatever reason, and that's why I'm grabbing it each function. Thanks for pointing the errors of my ways. JS startRotateDiv(); function startRotateDiv() { var rotateDiv = $('#home_div div.content_image'); var tl = new TimelineMax({repeat:-1}); tl.add(setText); tl.to(rotateDiv,.5,{autoAlpha:1}); tl.to(rotateDiv,.5,{autoAlpha:0},"+=2"); tl.play(); } function makeid(len) { var text = ""; var possible = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789"; for( var i=0; i < len; i++ ) text += possible.charAt(Math.floor(Math.random() * possible.length)); return text; } function setText() { var rotateDiv = $('#home_div div.content_image'); var txt = makeid(1); rotateDiv.html('<div class="notice">'+ txt + '</div>'); } CSS .notice { font-size: 80px; font-family: 'noticenotice2'; color: red; background: url('http://media.npr.org/assets/news/2010/04/11/panda-f8a7c9331bbac776e52b26feeccc53de959f46d1-s6-c30.jpg'); }

Hi, I'm studying the video-tutorial "advanced sequencing - meet the blobs". http://hub.tutsplus.com/tutorials/timelinelite-ultimate-starter-guide-advanced-sequencing--active-10331 by Carl Schooff I want to rebuild it in javascript not AS. in the video at 25'45 I'm stucked with looping through the blobani timeline with insertMultiple and push the created timelines into an array. var blobTweens = new Array(); function createBlobs() { for (var i=0; i<10; i++){ var blob = $("#blob"); var blobani = new TimelineLite(); blobani.insertMultiple([ TweenLite.to(blob, 2, {x:480}), TweenLite.to(blob, 0.5, {y:-250}), TweenLite.to(blob, 0.5, {rotation:360, delay:.1}), TweenLite.to(blob, 0.5, {y:-140, delay:0.5}) ]); blobTweens.push(blobani); or blobTweens = (blobani); } } I can't push the timelines that were created by the for loop into the blobTweens array. can you please help me with the right javascript syntax for this wonderful idea to create multiple objects? thank you for the timeline guide videos and for your answer Michael

Hello everyone, I have just launched a new website: http://html5maker.com It exports frame-based animations using TweenMax library. Currently only Move and Fade effects are supported but I plan to add more effects in future. Here are some templates that were done using html5maker. Waiting for your feedback and feature requests! Thanks!

Hi, I'm "converting" to GSAP, and I just can't seem to find anything regarding external use in any of the documentation. Please visit www.duwaynebrown.com to see what I have now. Since I don't see "typewriter" plugin under the tweens, I'd like to know if I would be able to create an instance in the timeline where it would call the typewriter() function ? Also, the h2, how would I "convert" that to tweening ?

I have two timelines.. tl1, tl2 for demonstration purposes. tl1 starts when the dom is ready. tl2 starts via button click. There is another button that reverses everything to where tl1 starts. The problem I have is that if the button that starts tl2 is clicked before tl1 is finished, then someone clicks the button that reverses the timelines to the start of tl1, then tl1 is reversed to the point where the interruption happened. How can I tell the button that reverses everything back to tl1 to go all the way back to zero?

Hey guys, Found some behaviour that's causing me issues. I have an animation of a vehicle, that's yoyo-ing from left to right infinitely. In the onRepeat callback i'm flipping scaleX between 1 & -1 to flip the graphic. The problem happens when the browser tab is not active. The timeline may have repeated multiple times, however the onRepeat callback is only fired once when focus is returned to the tab. Therefore the orientation of the graphic can become out of sync with the actual direction. I realise that RAF halts all callbacks when the tab is inactive so, but I would have expected the onRepeat callback to be fired retroactively for the number of times the animation has technically repeated. Is the behaviour intended or a GSAP bug? For the moment I have changed my code to manually change direction based on the x vector in the onUpdate callback. Hope I've not rambled too much Look forward to your reply. Rob

Hello everyone, let me say at the beginning that this is a fantastic animation platform, since I've been only working a little bit with jquery animate, this is way easier to work with, good job. And now here comes my problem. So I'm trying to make a CPU scheduling animation, pretty much the same thing as here on this link: http://courses.cs.vt.edu/csonline/OS/Lessons/Processes/index.html My problem here is that I'm not really sure can this even be done. So let's say I have 10 processes which are represented as a small images, and animation is just moving those images across screen, nothing to fancy. My idea is very simple and it goes like this: - take process from ready queue and animate it to the CPU - there wait for few seconds and animate it to waiting queue - there also wait for few second and animate it back to waiting queue - repeat this untill all processes are finished (bool variable) Ofcourse when one process finishes in CPU other from ready queue is comming in. And when process is in waiting queue, the rest of simulation should be running. So if I wouldn't have waiting queue this would be very easy animation to do, but with it in game it gives me troubles. My possible solution to this would be using 2 timelines, one which would animate processes in ready queue and to the CPU, and other timeline which would animate them from CPU to the waiting queue and back to the ready queue. The problem is I'm not sure how to do it. Can anybody give me some tips or link to some tutorial where something similar is done, it would be much help. Tnx

I have a few tweens as part of a TimelineMax instance that have a speed of 0. However they are executing out of sequence with the rest of the tweens, seemingly running at the very start of the timeline playback. Changing the speed to 0.1 fixes this issue. Here's a fiddle: http://jsfiddle.net/wxxkA/2/ Any ideas? Thanks

Hi there! I hope that somebody can help me out with a problem I stumbled upon. I want to animate on a scroll by using the superscrollorama plugin. With GSAP I can use a timeline to change the position of an element on scrolling. I want the following actions to take place: Move the element from -1900px to 550px on screen by scrolling After that, let the element stay at it's position while scrolling a certain amount of pixels (let's say 2000px) After the 2000px without movement, let the element move from it's current position to 1900. So we have an animation of an element from the left side of the screen, to the right with a pin moment. I hope someone can help me out here because I have not succeeded in writing a code that doesn't conflict with the first animation and a pin moment. This is what I have so far: controller.addTween('body',(new TimelineLite()).append([TweenMax.fromTo($('#vogel'), 1, {css:{left: -1900}, immediateRender:true}, {css:{left: 550}})]), 1000);

Hello, I'm starting to go nuts about this little animation I got going on with your very cool platform. This is what I want to happen (storyboard): #color_circle_1 (fadein) -> #color_circle_2 (fadein) -> #color_circle_3 (fadein) -> #color_circle_4 (fadein) -> Menu (slide down) -> #color_container (moves down and gets a smaller height). And then comes my problem. The #color_container does as wanted to, but the #color_circle_(1-4) moves down with it, but I want them to stay in the same position and not move with the Container. Does anyone have any ideas of how I could fix this tiny problem? I tried out several things, but I keep up getting the same animation. That the #color_circle_(1-4) keeps moving down with the Container moving down. So in basics I want colored circles to stay at their position while the Container animates smaller.

Hello again, I'm now moving on to the menu. How do I setup the menu (styled it etc..), so what I want is that once you click on a menubutton it auto scrolls down to that page/section. And my question is. How do I do that? Because when I look at the demo of this I don't see any demo with an actual functioning menu. There is a lot about effects and animations, but nothing in it about how to make all of that work with a navigation also. Does anyone got some kind of tutorial on 'How to make a menu that scroll to page/section'? Maybe there is a tutorial somewhere that I have missed?

Hi, Since the introduction of animation in JS, ad management programs are changing the standard of Flash to JS when it comes to advertisement. But they keep the same restrictions on KB. When I was given the task to make a banner in JS, Greensock immediately popped up in my head. I've looked at the download page and when customising the library I saw 7 kb when only selecting Tweenlite. As shown here: But when I look on my mac when inspecting the file: Am I doing something wrong downloading or am I missing something here? For the banner to be accepted @ the ad networks the JS should be under 10kb. Hope someone can help me out! Thank in advance! Youri

Having trouble getting the Greensock machine gun effect to work on my site.

I need some kinda trouble shooting article Thanks Mark

Hi everyone! Let me start by saying GSAP is awesome. I was wondering if anyone had ported the RoughEase library from AS to JS, or something similar to that? I'm working on a project where I need to randomly affect elements over time (smoothly), and I think RoughEase would be amazing for the job. More specifically, I'm trying to replicate some old film effects – grain, shifting picture, flickering bulb, etc. My current solution is to start a tween for a random duration/value, then delay the next tween by a random amount, and have that process loop, effectively creating a sort of randomness to the flicker. I suppose it works, but it doesn't look great yet and doesn't feel as elegant as the RoughEease soltuion. Thanks in advance!

I'm asking, because I'm trying to make that works inside Edge, but there's no results. I tried to go with several versions of this code from official plugin website: $(document).ready(function() { var controller = $.superscrollorama(); controller.addTween('#fade', TweenMax.from($('#fade'), .5, {css:{opacity:0}})); }); but non of them seem to do anything correctly. In example, if I do something with: var controller = $.superscrollorama(); and change it to: var controller = sym.$("superscrollorama"); then Edge seems to ignore almost whole code and acts like there is only the TweenMax.to function. If there is anyone who knows the answer to solve this problem, please, be so kind. But first of all, I want to say hello to all of You here as a new user of this forum.

Hi guys, I've been having a play around with the JS animations for a few weeks now (having loads of fun making stuff fly about the place!) but have decided to notch it up a level and try some 3D animations. Basically I'm trying to rotate a 3D cube around the Y axis and am having an issue getting the 4 front facing sides of the cube to stay where they should be. They sort of 'bounce' from the edge of the cube by a small margin. I've setup a fiddle to help explain the issue for which I've taken out 3 of the cube faces to showcase the issue - http://jsfiddle.net/rockerby/sVTaU/1/ I've tried playing around with the transform origin rather than animating the 'z' and 'x' properties on rotate but can't seem to get this to look right. Any help would be greatly appreciated!

I am using TimelineMax for a project and I was wondering is there was a way to possibly update the CSS attribute of a Tween by calling it's label? For example my tween would look like: var tl = new TimelineMax({paused:true}); tl.to(element, time, {css:{top: -50px}}, "my-label"); I would like to possibly call this tween by it's label and update the CSS property to a new value. I tried something like this, but I had no success. tl.removeLabel("my-label"); tl.insert(TweenLite.to(element, time, {css:{top:-100px}}), "my-label"); Any help would be appreciated.

I have a scrolling set of thumbnails that is fed from a backend — thus a varying amount of images. These are masked by a div with overflow:hidden. The thumbnails scroll left and right depending on where mouse is over them (left or right) and also with two external arrows: mouseOver over the arrows scrolls the thumbnails left and right. I set up the entire thing as a TimelineMax. Very nice -- play from 0 to 1 depending or reverse it, if I want to go the other way. The issue I'm running into is making this work on an iPad. The client doesn't want me to invest the time into setting it up for full touch responsiveness, which I recommend — so my only thought is to scroll based on the arrows. — MouseDown doesn't work — just asks if I want to download the arrow images — So I'm thinking: click — but given that I've got it all set up as a TImelineMax, how do I do this? I could of course just do a simple TweenMax a given number of pixels, but again, would like to tween, say, from TimelineMax progress 0 to, oh, 0.1 or something — I reckon I can calculate the appropriate amount given the total width of the images and the masking div — Anyway to move a TimelineMax in pieces like this? Would I do a TweenMax of the TimelineMax's progress() ?? Thanks for any help — and yes, I know I should do the touch interface, but the client needs to give the go ahead…

Recently I found a background color animation was failing in IE8, this was because I was reading the color to tween to from a hidden div and IE8 was returning the value as 'whitesmoke'. It's easy enough to use a lookup table as here: http://stackoverflow.com/questions/1573053/javascript-function-to-convert-color-names-to-hex-codes But might be nice if this was handled internally by the CSS plugin.
