Sure Jeswen, isometric is easy... if the world is completely flat.
Somehow I doubt that's what Posessed wants though.
Haha, no ... you treat each layer of depth as a flat world ... adding a second layer of height means changing a value from 1 to 2 and adding it as a condition.
It's not so difficult
This is why I say, pretend it doesn't have depth. Look at everything as flat. You make it too complex if you treat Z as an actual depth position rather than "layer 2" etc.
On a side note, I'll be sure to be a smart ass towards you yet again deadeye, since you give me the honor!
