ActionScript 3.0 Note

because it's very important
so I need write it down
if you create a lot animation flash 2D game (include sprite sheet, video, particle)
most of time we will use starling to developer(GPU render)
but texture have resource limit
so my experience is :
1. 1280x720 (don't use 1920x1080)
2. StarlingSwf (very useful tools for timeline animation)
3. object pool (don't create object every time, or you need be sure texture dispose)

good luck have fun

as3 starling gif decoder use https://github.com/honzabrecka/async-gif-decoder if you need refresh gif gallery all the time, or need show a lot gif image in same time use this library will have memory problem so you need modify "com/jx/gif/GPUGIF.as" change cachedTextures to public public var cachedTextures:Vector.; then in your code, every time refresh GPUGIF, you need if(gif.cachedTextures){ for(i=0;i < gif.cachedTextures.length;i++){ gif.cachedTextures[i].dispose(); } gif.dispose(); gif.texture.dispose(); } in this way, you can free 90% memory, if you have better way please let me know!! :)

var degrees:Number = radians*180/Math.PI ;

var boolValue:Boolean = (boolString == "true") ? true : false; just one line! I like it!
