|	layeredAnimation - a plugin for ImpactJS	|
-------------------------------------------------


DESCRIPTION:

Tested on ImpactJS version 1.19

Allows you to add "layers" to an animation sheet - it injects 2 new methods into ig.AnimationSheet:

- addLayer(path) : adds another "layer" (sprite sheet) over the existing sprite sheet.
	path: the path to the animation sheet to layer over the rest - must be the same dimensions as your base animation sheet (duh).

- removeLayer(path) : one guess......



USE: 

1. create a "plugins" directory within /impact/lib/, and save 'layeredAnimation.js' in this directory.

2. In your entity class, include 'plugins.layeredAnimation' within .requires(), and use the addLayer() method to add additional layers over your base sprite sheet, i.e.:



EXAMPLE ENTITY:

ig.module(
	'game.entities.player'
)
.requires(
	'impact.entity',
	'plugins.layeredAnimation'
)
.defines(function(){

EntityPlayer = ig.Entity.extend({
	
	init: function( x, y, settings )
	{
		this.animSheet = new ig.AnimationSheet( 'media/some-character.png', 64, 64 );
		this.animSheet.addLayer( 'media/some-character-HELMET.png' );
		this.addAnim('idle', 1, [0] );

		this.parent( x, y, settings );
	}

});

});
