A sprite is an object rendered on a {@link Surface} in a {@link DrawComponent}. To be rendered a sprite must first be added to a draw component. Then to update the rendered version after the initial attachment call the sprite's {@link #redraw()}:
```
 RectangleSprite rectangle = new RectangleSprite(100, 100); rectangle.setFill(RGB.RED); DrawComponent draw = new DrawComponent(100,100); draw.addSprite(rectangle); 
```
Sprites can also be redrawn by using the {@link DrawComponent#redrawSurface()} to tell the surface render all sprites currently attached to it.

    if (index == 0) {
      if (surfaceElement.getChildIndex(element) != 2) {
        surfaceElement.insertChild(element, 2);
      }
    } else {
      Sprite previousSprite = sprites.get(index - 1);
      XElement previousSpriteElement = getElement(previousSprite);
      if (previousSpriteElement == null) {
        previousSprite.redraw();
        previousSpriteElement = getElement(previousSprite);
      }
      if (previousElement != previousSpriteElement) {
        surfaceElement.insertAfter(element, previousSpriteElement);
