Multi-Dimension Array Mapping Problem.

I've been trying to convert one of TonyPa's tutorials to a 2.5D sort of perspective. I wanted to add an extra layer on top of the one loaded when entered, so I can use depth (transparency with trees to make it easier).

I do not know how to come across this. Either making another array and loading it at a higher depth, or, creating an array inside the array, then trying to load it.

I'm trying it with this tutorial. Source is at the bottom.

Help through modded source file will be most welcome.
