package cz.fishtrone.utils
{
	import starling.display.Image;
	import starling.textures.Texture;
	
	
	/**
	  * Give a texture that is made of {parts} images, one below another, spaced evenly and specify which image {part} you want to see
	  */
	public class MultipartImage extends Image
	{
		public function MultipartImage(texture:Texture, part:int, parts:int = 4)
		{
			super(texture);			
			setTexCoordsTo(0, 0, part/parts);
			setTexCoordsTo(1, 1, part/parts);
			setTexCoordsTo(2, 0, part/parts+1/parts);
			setTexCoordsTo(3, 1, part/parts+1/parts);			
		
			mVertexData.setPosition(2, 0.0, height/parts);
			mVertexData.setPosition(3, width, height/parts);
		}
	}
