I'm looking for the best way to implement layers to my map. I'd like to have up to 4 layers. I will be cycling through and doing a DrawImage to display it. What is the best method? List, Array, Map, Stack?

I can do a 2 dimensional array. How would I do a 3 dim one? Is it even needed?

You can actually use any collection you prefer for each dimension. In practice, of course, it is advisable to avoid anything too complicated.

A 3D array is simply an array of 2D arrays[*]. Probably if you have a world with four 'heights' this is the correct approach.

[*] Just as a 2D array is simply an array of 1D arrays.
