Spritesheet is a animation library for animating bitmap sequences in a Haxe projects. Provides support for common sprite sheet importers.

To install a release build:

haxelib install spritesheet

If you prefer to use development builds:

git clone https://github.com/jgranick/spritesheet
haxelib dev spritesheet spritesheet

To include Spritesheet in an OpenFL project, add <haxelib name="spritesheet" /> to your project.xml.

It's simple to get started! To see your sprite animating you will need a bitmap, a Spritesheet, and a AnimatedSprite.

Get the BitmapData for your animation

var bitmapData = Assets.getBitmapData("some_sprite_sheet.png");

Spritesheet includes some basic factory methods for common bitmap sprite sheets. This will seed the frames into the Spritesheet.

var spritesheet:Spritesheet = BitmapImporter.create( bitmapData, 3, 9, 56, 80);

Behavior consisting of a name and the cells that should animate

spritesheet.addBehavior( new BehaviorData("idle", [3, 4, 5], false, 15) );

AnimatedSprite sheet will be your view and is added to the stage

var animated:AnimatedSprite = new AnimatedSprite(spritesheet, true)
addChild( animated );

Tell the sprite what behavior to play

animated.showBehavior("stand");

Finally, tell the sprite when to animate and the delta since the last update, in this case we'll be updating via Event.ENTER_FRAME.

private function onEnterFrame(e:Event):Void
{
 var time = Lib.getTimer();
 var delta = time - lastTime;
 animated.update(delta);
 lastTime = time;
}
