  1. Note: the ActionScript version of the GreenSock Animation Platform still works great and you're welcome to use it, but it is no longer officially supported. Our customer base made it very clear that JavaScript was the future of web-based dynamic animation, and we have been focused there for years. Please see the JavaScript Getting Started Guide for more information. Quick links Introduction Installing the code Importing Basic tweening with TweenLite Special properties Plugins Overwriting other tweens Controling tweens Which class do I use? TweenLite? TweenMax? TweenNano? Building a sequence with TimelineLite Need help? Introduction Animating with code may seem intimidating at first, but don't worry - you'll get the hang of it quickly. The GreenSock Animation Platform (GSAP) was engineered to make it simple and intuitive. For now, we'll focus on getting you up and running with the core engine, TweenLite, and then we'll discuss if and when you might want to put the other tools to work for you (like TweenMax, TimelineLite, TimelineMax, etc.). Installing the code Go to your account dashboard page and click the AS2 or AS3 link in the downloads area to download a zip file containing the entire GreenSock Animation Platform in the language you specified. Unzip the file and you'll see a folder containing several swfs, documentation, and a folder named "com" - that's the critical one. Take that "com" folder with all its contents and drop it into the same folder as your FLA file (or if you're an advanced user, set up a classpath to wherever you want). Make sure that you leave the directory structure inside the "com" folder in-tact; it has a "greensock" folder with several ActionScript files inside, along with a few subdirectories. You can throw away the swfs from the zip download and the documentation, etc. if you want. The only critical files are inside that "com" folder. When you publish your swf, Flash looks for that "com" folder, reads the code from inside of it, and embeds it into your published swf. You do NOT need to put the "com" folder on your web server. Once the swf is created, it is completely independent and has no dependencies on the class files because they have been embedded into the compressed swf. Your FLA file has the dependencies, not the swf. There's a great ActiveTuts article here about using 3rd party tools in your Flash projects and it covers some of the more advanced installation/configuration options. Importing In order for Flash to understand what you mean when you type "TweenLite" (or "TweenMax" or any of the GreenSock classes), you must tell it where to find the class file(s). That's what an import statement does. It acts as a pointer that tells Flash where it should look. After all, there could be a completely different "TweenLite" class that another author created, and you need a way to tell Flash which one you're talking about. Typically you put your import statement at the top of the frame or the custom class you created. And, yes, just like any class, you must add the import statement to all frames or classes that contain code referencing it. This does not add extra kb to your file every time you import it. Flash is smart enough to embed it once and all the import statements just act as a "pointer" to the embedded class. To import just the TweenLite class, do: import com.greensock.TweenLite; To import TweenLite and TweenMax, do: import com.greensock.TweenLite; import com.greensock.TweenMax; To import all of the classes in the com.greensock package (don't worry, Flash will only embed the classes that you actually use in your code), do: import com.greensock.*; You'll probably also want to import the easing classes as well (we'll talk more about them later), so this is code that you should get used to putting at the top of your frames or class files because it covers almost everything you'd need and it's shorter than typing out each class every time: import com.greensock.*; import com.greensock.easing.*; Basic tweening with TweenLite Each tween you create needs a target (the object you want to tween), the duration of the tween (typically described in seconds), and the properties that you want to tween, along with their corresponding end values. Let's say, for example, you have a MovieClip named "mc" and you'd like to tween its x property to a value of 100 (sliding it across the screen) over the course of 1.5 seconds. You can use TweenLite's to() method to do it: TweenLite.to(mc, 1.5, {x:100}); The first parameter is the target, the second is the duration, and the third is an object with one or more properties that correspond to your target object's properties. Since it's a to() tween, you're telling TweenLite to tween from whatever the x property happens to be at the time the tween begins (now in this case), to a value of 100. If you want to also tween the y property to 200 and the alpha property to 0.5, you'd do: TweenLite.to(mc, 1.5, {x:100, y:200, alpha:0.5}); There is no limit to the number of properties you can tween. And TweenLite can tween any numeric property of any object, not just a predetermined list of DisplayObject/MovieClip properties. Since there's an AS2 version as well, you can simply change the property names to reflect their AS2 equivalents, like: TweenLite.to(mc, 1.5, {_x:100, _y:200, _alpha:50}); Here's an interactive demo that allows you to build tweens yourself and see the corresponding code at the bottom: There is also a very useful from() method that allows you to define the starting values in the tween and go backwards. So the current values will be used as the end values, and the ones you define in the tween will be the starting values. This makes it easy to, for example, set things up on the stage where you'd like the objects to end, and then animate them into place. Let's say your mc object's y property is at 200 and alpha is at 1, and you'd like to have it "drop" into place from above while fading in over the course of 1.5 seconds, you could do: TweenLite.from(mc, 1.5, {y:0, alpha:0}); If you prefer a more object-oriented approach and/or would like to store references to your tweens in variables so that you can control them later (for example, pause(), resume(), reverse(), restart()), you can create a tween like this (which is identical to a to() tween): var myTween:TweenLite = new TweenLite(mc, 1, {x:100, y:200, alpha:0.5}); Special properties A special property is a reserved keyword that TweenLite recognizes and handles differently than it would a normal property. One example is delay which allows you to delay a tween from starting until a certain number of seconds has elapsed. For example, this tween will wait 2 seconds before beginning: TweenLite.to(mc, 1, {x:100, delay:2}); TweenLite recognizes several special properties that are quite useful, like onComplete, ease, overwrite, paused, useFrames, immediateRender, onStart, onUpdate, onCompleteParams, and more. Please read the full documentation for details. Two of the most common special properties you'll likely use are ease and onComplete. To alter the rate of change during a tween, you can choose from many different easing equations from either the com.greensock.easing package or Flash's own easing classes or Robert Penner's. The interactive demo above allows you to chose different equations and see how they affect the tween. The onComplete special property gives you a way to call any function when the tween completes, making it simple to create a chain of events. Here is a tween that uses the Elastic.easeOut ease, delays its start time by 0.5 seconds, and calls myFunction() when it completes: TweenLite.to(mc, 1.5, {x:100, ease:Elastic.easeOut, delay:0.5, onComplete:myFunction}); function myFunction():void { trace("tween finished"); } Plugins Think of plugins like special properties that are dynamically added to TweenLite (and/or TweenMax), giving it extra abilities that it doesn't normally have by default. Each plugin is associated with a property name and it takes responsibility for handling that property. For example, the FrameLabelPlugin is associated with the frameLabel property name so if it is activated it will intercept the frameLabel property in the following tween and manage it uniquely: TweenLite.to(mc, 1, {frameLabel:"myLabel"}); If the FrameLabelPlugin wasn't activated, TweenLite would act as though you were trying to literally tween the mc.frameLabel property (and there is no such thing). Activating a plugin requires a single line of code and you only need to do it once in your application, so it's pretty easy. Simply pass an Array containing the names of all the plugins you'd like to activate to the TweenPlugin.activate() method, like this: import com.greensock.plugins.*; TweenPlugin.activate([FrameLabelPlugin, ColorTransformPlugin, TintPlugin]); To make it even easier, I created the Plugin Explorer which writes the code for you. All you need to do is select the plugins and copy/paste the code from the bottom of the tool. It also displays interactive examples of each plugin and the associated code so that it's easy to see the correct syntax. TweenLite does not activate any plugins by default, but TweenMax does. When a plugin is activated, it affects both TweenLite and TweenMax. Overwriting other tweens An often overlooked aspect of tweening is how (and if and when) tweens overwrite other tweens of the same object. For example, let's say you have a button with ROLL_OVER and ROLL_OUT handlers that tween its alpha higher on ROLL_OVER and lower on ROLL_OUT. To further complicate things, let's say the ROLL_OVER tween lasts 2 seconds and the ROLL_OUT tween lasts 1 second. What should happen if the user rolls over/out/over/out quickly? See the problem? If tweens are allowed to run without any kind of overwriting, they'll build up and fight with each other (one trying to tween the alpha higher, and the other lower). In this example, when the user rolls over, a 2-second tween would start increasing the alpha to 1, but if the user rolled off 0.2 seconds later, another tween would begin, causing the alpha to decrease. When that tween finishes 1 second later, the ROLL_OVER tween is still going (since it had a duration of 2 seconds), so the alpha would suddenly jump up and finish off at a value of 1 even though the user rolled out! Don't worry. We've got you covered. By default, whenever a TweenLite instance renders for the first time (after any delay), it analyzes all other active tweens of the same target and checks for individual overlapping properties. If it finds any, it kills the offending overlaps (again, only the individual properties). This overwrite mode is called "auto" and it is typically the most intuitive. However, there may be times when you want the new tween to kill all other tweens of the same object regardless of their start times or overlapping properties. That is what the "all" overwrite mode is for. And to skip overwriting altogether, you can define an overwrite mode of "none". There are several other modes to choose from too, so check out the full docs for details. You define an overwrite mode with the overwrite special property like this: //overwrites all tweens of mc immediately TweenLite.to(mc, 1, {x:50, overwrite:"all"}); //doesn't overwrite anything (allows conflicts) TweenLite.to(mc, 1, {x:50, overwrite:"none"}); //overwrites only individual overlapping properties on concurrent tweens of mcmyElement (this is the default, so you typically don't need to specify any overwrite in this scenario) TweenLite.to(mc, 1, {x:50, overwrite:"auto"}); //set the default overwrite mode to "all" instead of "auto" TweenLite.defaultOverwrite = "all"; Of course you can manually kill all the tweens of a particular object using the TweenLite.killTweensOf() method, but the nice thing about defining overwrite modes is that the overwriting doesn't kick in until it's necessary (when the tween renders for the first time) which is essential when working with complex sequences. Controlling tweens Once a tween is created, you may want to pause(), resume(), reverse(), play(), restart(), invalidate(), or kill() it. It's pretty easy, actually: var myTween:TweenLite = new TweenLite(mc, 1, {x:100, y:100}); //pause myTween.pause(); //resume (honors direction - reversed or not) myTween.resume(); //reverse (always goes back towards the beginning) myTween.reverse(); //play() (always goes forwards) myTween.play(); //restart myTween.restart(); //invalidate (clears out any starting values that were recorded and forces the tween to re-initialize on the next render) myTween.invalidate(); //kill the tween immediately myTween.kill(); //kill all tweens of the mc object TweenLite.killTweensOf(mc); TweenMax has some additional static methods for getting all the tweens of a particular object, pausing them all, resuming, getting tweens of objects that are children of a certain DisplayObject, and more (see documentation for details). Which class do I use? TweenLite? TweenMax? TweenNano? If you can afford the file size (roughly 23kb with the default plugins), just use TweenMax. It is the most full-featured tweening engine and it automatically handles activating a bunch of useful plugins by default, so it makes things very easy. If, however, you're concerned about file size and want precise control over which plugins get activated, TweenLite is for you. It's amazingly capable for its size and has all the essentials crammed into about 8kb. It is really the core of the whole platform and has become incredibly popular. If you simply must shave off another 6k and are willing to sacrifice quite a few features (most notably lack of support for plugins and insertion into TimelineLite/Max instances), use the ridiculously small 2k TweenNano. I would strongly recommend sticking with TweenLite or TweenMax if you can, though, because they offer much more flexibility than TweenNano. All of the engines use exactly the same syntax, so these lines will produce identical results: TweenNano.to(mc, 1.5, {x:100, y:200, onComplete:myFunction, ease:Strong.easeOut}); TweenLite.to(mc, 1.5, {x:100, y:200, onComplete:myFunction, ease:Strong.easeOut}); TweenMax.to(mc, 1.5, {x:100, y:200, onComplete:myFunction, ease:Strong.easeOut}); Keep in mind that TweenMax extends TweenLite, so it does everything TweenLite does, plus more. And the plugins that are activated by default in TweenMax can also be activated in TweenLite (the only exception being roundProps), so with a couple of extra lines of code at the start of your application, TweenLite can have many of the same capabilities as TweenMax (activating plugins increases the file size beyond 4.7k obviously). There are several features that are only available in TweenMax, though, so check the documentation. Sequencing and grouping tweens with TimelineLite Unlike most other scripted animation tools, sequencing in GSAP is much more flexible than building a queue of tweens that run one-after-the-other. You have complete control over the relative timing of each tween - they can overlap as much as you want. And you can control entire sequences as a whole, reverse smoothly anytime, jump to any point, adjust the timeScale(), etc. and everything renders in the proper order. Watch this video for a visual demo showing how TimelineLite can save you a lot of time. Although the video uses the HTML5/JavaScript version of GSAP, the same concepts apply to ActionScript. Of course you could sequence tweens by using the delay special property on all your tweens, but that can get complicated when you build a long sequence and then later want to change the timing of something early in the sequence (you'd have to adjust all the delay values in tweens after that). Plus it would be a pain to control the whole sequence, like to pause() or resume() or reverse() the group on-the-fly. Sequencing is much easier with TimelineLite and its big brother, TimelineMax. Let's jump into some sample code: //create a TimelineLite instance var tl = new TimelineLite(); //append a to() tween tl.to(mc, 1, {x:50}); //add another sequenced tween (by default, tweens are added to the end of the timeline which makes sequencing simple) tl.to(mc, 1, {height:300p, ease:Elastic.easeOut}); //offset the next tween by 0.75 seconds so there's a gap between the end of the previous tween and this new one tl.to(mc, 1, {alpha:0.5}, "+=0.75"); //overlap the next tween with the previous one by 0.5 seconds (notice the negative offset at the end) tl.to(mc, 1, {rotation:360}, "-=0.5"); //animate 3 MovieClips (mc1, mc2, and mc3) to a rotation of 60 degrees, and stagger their start times by 0.2 seconds tl.staggerTo([mc1, mc2, mc3], 1, {rotation:60}, 0.2); //then call myFunction() tl.call(myFunction); //now we can control the entire sequence with the standard methods like these: tl.pause(); tl.resume(); tl.restart(); tl.reverse(); tl.play(); //jump to exactly 2.5 seconds into the animation tl.seek(2.5); //slow down playback to 10% of the normal speed tl.timeScale(0.1); //add a label named "myLabel" at exactly 3 seconds: tl.add("myLabel", 3); //add a tween that starts at "myLabel" tl.add( TweenLite.to(mc, 1, {scale:0.5}), "myLabel"); //jump to "myLabel" and play from there: tl.play("myLabel"); Think of a timeline (as in a TimelineLite or TimelineMax instance) like a collection of tweens that are positioned at specific places on that timeline. It controls their playback. Timelines can be nested inside other timelines as deeply as you want. This is a very powerful concept because it allows you to control entire sequences in a modular way. Imagine 100 characters individually animating into place in a staggered fashion (100 tweens). They could all be grouped into a TimelineLite instance and then controled as a whole (using common methods like pause(), resume(), reverse(), restart(), etc.). In fact, you could create functions that return animations wrapped in a TimelineLite so that you can easily build a larger, more complex animation in a modular way. A central concept to grasp is that every tween is inserted into a timeline. By default, it's the root timeline inside the engine. When a timeline is playing, its virtual playhead advances. If you reverse() a timeline, the playhead travels in the opposite direction back towards its beginning. As the timeline's playhead encounters tweens, it plays them accordingly. For example, if the playhead is positioned halfway through a tween, that tween will render as though it is 50% finished. If the timeline's timeScale() is set to 0.5, that would cause the playhead to travel at half speed. Consequently, any tweens it encounters would also appear to progress at half speed. Once you get the hang of how timelines work, they can revolutionize your animation workflow. Just like tweens, timelines play immediately by default but you can pause them initially using pause() or by setting paused:true in the vars parameter of the constructor. There are quite a few methods available in the timeline classes that give you precise control, and we'd encourage you to look through the docs to see what's available. If you can think of something you'd like to do, chances are there's a way to do it. Just like the way TweenMax extends TweenLite, TimelineMax extends TimelineLite, using identical syntax and adding several useful (but non-essential) features like AS3 event dispatching, repeat(), repeatDelay(), getActive(), getLabelAfter(), getLabelBefore(), currentLabel(), and more. Please refer to the TimelineMax documentation for details. Here's an interactive demo of TimelineMax: Need help? Feel free to post your question on the forums. Keep in mind that you'll increase your chances of getting a prompt answer if you provide a brief explanation and include a simplified FLA file (and any class files) that clearly demonstrates the problem.
  2. I found this very nice previous post, but I can´t make it work on adobe animate....any ideas from any actioscript guru?
  3. I am using tween max in flash and I am using glow filter effect on a movieclip it works well when debugging on computer but when I try to use it on mobile the glow effect doesn't happen Is it not supported on mobile? here's the code: TweenMax.to(mc,1,{delay:1.5,glowFilter:{color:0xff0000,alpha:1,blurX:40,blurY:40,strength:1.5}}) any help?
  4. Hi, I'm not really a coder, was hoping for some help. Trying to convert some Flash banners to HTML5. There is some Greensock scripting in the file and I need to rewrite for HTML5. Code below. Could anyone tell me how to rewrite these functions? function initTween_pig1() { com.greensock.TweenNano.from(pig1_mc, 1.7, {_alpha: 0, _xscale: 0, _yscale: 0, ease: com.greensock.easing.Elastic.easeOut}); } function initTween_pig2() { com.greensock.TweenNano.to(pig2_mc, 1.7, {_alpha: 100, _xscale: 150, _yscale: 150, ease: com.greensock.easing.Elastic.easeOut}); } function initTween_pig3() { com.greensock.TweenNano.to(pig3_mc, 1.7, {_alpha: 100, _xscale: 200, _yscale: 200, ease: com.greensock.easing.Elastic.easeOut}); } function initTween_pig4() { com.greensock.TweenNano.to(pig4_mc, 1.7, {_alpha: 100, _xscale: 250, _yscale: 250, ease: com.greensock.easing.Elastic.easeOut}); } function initTween_pig5() { com.greensock.TweenNano.to(pig5_mc, 1.7, {_alpha: 65, _xscale: 400, _yscale: 400, ease: com.greensock.easing.Elastic.easeOut}); } function initTween_pink() { com.greensock.TweenNano.from(pinkSquare_mc, 0.1, {_alpha: 0, ease: com.greensock.easing.Linear.easeIn, overwrite: 1}); } initTween_pig1();
  5. I've just started using AS & TweenLite / TweenMax. But I can't seem to get a blurFilter to apply. I have done this so far, package { //Import what I need to import com.greensock.TweenLite; import com.greensock.easing.Linear; import com.greensock.plugins.BlurFilterPlugin; import com.greensock.plugins.ColorTransformPlugin; import com.greensock.plugins.TweenPlugin; import org.flixel.FlxG; import org.flixel.FlxState; import org.flixel.plugin.photonstorm.FlxSpecialFX; TweenPlugin.activate([blurFilterPlugin]); public class ScreenTwo extends FlxState { private var Bwain:Brain; private var bg1:BackgroundOne; //Active plugins TweenPlugin.activate([blurFilterPlugin, ColorTransformPlugin]); override public function create():void { super.create(); Bwain = new Brain(0,0); bg1 = new BackgroundOne(0,0); FlxG.addPlugin(new FlxSpecialFX); //Here I try to tween it. TweenLite.to(bg1, 3, {blurFilter:{blurX:10, blurY:10}}); TweenLite.to(Bwain, 10,{x:-120, ease:Linear.ease}); add(bg1); add(Bwain); makeRed(); } private function makeRed():void { //TweenMax.to(Bwain,4, {ColorMatrixFilter:{colo } } } When I run it, the Linear tween works fine, but during the duration of the blur tween the program looks frozen and resumes after 3 second.
  6. Hello, I am having a little bit of trouble finding a way to remove the split text field from a textfield once I stop the animation its in. Long story short, I made a library which creates little timelines (sub-animations) for each animation (a timelineMax for flashing text, one for bouncing text, etc.). I give the end user the ability to combine all these little tiimelines into one big timeline, so that they may do something like the following: Text fades in, text flashes, text spins, text slides off screen All is working fine until one point. If one of those sub-animations uses a Split Text Field for its operation and the end user clicks the stop button before that sub-animation completes, the Split Text Field stays on the textField and I cannot find a way to remove it (usually the textField disappears). If needed, I can provide some code but I have a sneaky suspicion that there is a very simple and already completed solution for this exact issue. I can say that I do the following whenever the "stop" button is clicked as an attempt to fix the issue: (These are applied to the 'master' timeline) timeline.stop(); timeline.seek(0); timeline.clear(true); TweenPlugin.activate([blurFilterPlugin]); TweenMax.to(target,0,{blurFilter:{remove:true}}); Thank you in advance for your assistance!
  7. Hi, I am working on a project, in which I am trying to move 12 SWF files simontaneously with the help of (TweenMax.allTo). but when I try this in browser, many frames are skipping during movement. size of each SWF is 2500X2400 px and I'm using 4 MB jpg image in SWF as backfround. Code : TweenMax.allTo([CONTAINER_1, CONTAINER_2], groundFriction, { x:xPos, y:yPos} ); Both the containers are containing 6 SWF files. xPos and yPos is calculating dynamically on keyboard key down event, and I am using ENTER_FRAME to move the canvas. If someone knows how to deal with it, please help me. Thanks in advance.
  8. Hello guys How do I make that the object that I click, start moving in circles ( 2-3 times ) around the stage before arriving at its end position.Something like in this picture. PS: it doesnt have to have an exact radius or exact steps, it just has to rotate 1-2 times and after that go to the certain point on the stage. the way I figured out it could be is something like this: private function onClick( ev:MouseEvent ):void { var currentObj:Sprite = ev.currentTarget as Sprite; TweenLite.to(currentObj, 1, {x:first_X, y:first_Y, onComplete:goToPosition2 }); function goToPosition2():void { TweenLite.to(currentObj, 1, {x:secontd_X, y:second_Y, onComplete:goToPosition3 }); } function goToPosition3():void { TweenLite.to(currentObj, 1, {x:third_X, y:third_Y, onComplete:goToPosition4 }); } .. .. . . . //and so on and so on } yet I somehow feel that this is very wrong way of doing it. thanks.
  9. Hi guys, quick question - I've just grabbed the v12 version of the swc and it no longer recognises calls to the complete() method - has this been removed and if so, what is the accepted procedure to force a timeline to complete please (currently using tl.gotoAndStop(tl.totalDuration))? thanks obie
  10. Hi, I am facing a problem with controling the frames with audio in its timeline using TweenMax. Frames are playing perfectly but audio is not playing. If i try to play the swf normally using swf.play(); it works fine. Any clue why it might be happening??
  11. Hi, I am using 'selectionScaleX' & 'selectionScaleY' property to scale selected image. _transformManager.selectionScaleX = 0.5 _transformManager.selectionScaleY = 0.5 However it change the image x and y position. Is is possible to scale selected image object without changing image position? Thank You Regards, Bharat
  12. I'm getting an actionscript error on the console but i'm doing an HTML5 simple javascript tween.to. screenshot of error attached. see all files in action here-> http://polklein.com/gs
