What is the best mode for large 3d maps that includes hills and dips?

I don't think that SmileBASIC is powerful enough for that. About the best 3D you'll get is Raycaster.

Alright thanks.

@mystman: Eh, I disagree Raycasting is among the slowest 3D engine you can get, 'normal' 3D game engines just use a lot of math, and algorithms, but i'm sure smilebasic could make some decent 3D graphics without raycasting

Oh, ok, I'll do a little experimenting then.

Its the Z index sorting that usually uses the most processing, but as long as you use sprites, you dont need to worry about what sprites are behind what sprites It does it for you
