I am trying to work out a way of cutting holes out of a layer so that the true background is revealed through a second single "blanket" background. In the picture if you tapped any of the objects on the "Tile Layer" it would disappear and leave a cut-out the same size as the tile that goes as deep as Layer BG but without losing any more of Layer BG+1.
Until now I've simply been removing one object and creating another on top of it, but it is making the game very object heavy after a few minutes of destroying and discovering more blocks.
How do I accomplish this? From the picture the following is true:
Tile Layer = The tiles that sit on top of the game waiting to be tapped by the player.
Layer BG+1 = The background mask that sits on top of Layer BG.
Layer BG = True background image - burgundy colour.
