AnimatedTexture2D Class

The AnimatedTexture2D can be used to create animated textures on object. It takes a vertical spritesheet and returns a single frame based on the animation logic. It must be assigned as a texture to an Object in the Game Loop after the object has drawn.

Here is how the AnimatedTexture2D constructor looks:

export class AnimatedTexture2D{
	constructor(arcsci){
		this.arcsci = arcsci;
		this.spriteSheet = new Image();
		this.frameSizeX = 0;
		this.frameSizeY = 0;
		this.totalFrames = 0;
		this.currentFrame = 0;
		this.isSpriteSheetLoaded = false;
	}

    ...

}

The AnimatedTexture2D class has a setSpriteSheet() function which can be used to set the Sprite Sheet. It takes the spritesheet file path and the size of a single frame in the spritesheet as its parameter. It can be then assigned to a object as a texture by passing it calling the animate() funcion. This must be done in the Game Loop after the target object has been drawn.
