R0J0hound Ashley That's not quite what I'm talking about. At least I couldn't do it with your example :(
What I'm intending to do (in the game I'm actually working on) is setting a tiled background in Layer 0 that would occupy the whole layout space. This, on finished, will act as the path the player shall walk on to remain safe.
Then, on Layer 1, I will place all the elements of the game: the player, the weapons, the monsters...
Finally, on top of that last one, on Layer 2, i would place another tiled background with a free form, set by a polygon shape (with alpha channels filling the clear spaces), that would act, on finished, as areas of high grass where both the player and the monsters will be covered and barely seen, the latter hiding, waiting for the player.
That way, the scenario would look itself as a labyrinth with a clear path to walk and areas of high grass that would overlap all the scenario elements easily.
I couldn't do that with your example. Maybe you will be able.
