Curious.. I'm really just starting to learn what User Defined types are, and how to make them work. I'm working on a piece of code that generates a map, and I'm not sure how to go about assigning the values within my UDT. This is basically what I've got.

TYPE TILE
FrameNo as INTEGER
Walkable as INTEGER
Animated as INTEGER
MapExit as INTEGER
END TYPE

Dim MapGrid (30,30,30) as TILE

So.. .. how do I say "Tile FrameNo at MapGrid(1,1,1) = 10"

I'm just unsure on the proper syntax

MapGrid(1,1,1).FrameNo = 10

Just to give you some idea of size of your array...

1 integer = 4 bytes
4 integers = 16 bytes

30 * 30 * 30 elements = 27,000 elements

27,000 elements * 16 bytes = 432 Kilobytes.

Not massive, but you need to consider it in case you plan to interrogate many elements in a cycle.

Ah, no, the array holds the data for the entire map, but before I Start pulling elements from it, a quick check will be run to see which elements are actually on screen, so chances are the area that is actually read will be somewhere around 9 x 9 x 15 or so. Come to think of it, I can probably limit the Z value even more tightly
