hello, I have had a problem in many of my games about collision and I have hundreds of buildings and I need collision boxes for every single wall of each building. Is it possible to have a command calculate all of the collision data for all of the buildings (all of the buildings and terrain are one big object, made in ac3d) without having to make thousands of collision boxes, thank you in advance!

sov the game creator!

Yes.
You can do it mathematically if you know building positions in advance.

However, that would be extremely tedious. I think what you're looking for is polygon collision, where the player would collide with the actual parts of the world instead of a predetermined box. Try Sparky's Collision DLL. It features polygonal collision with the SC_SetupComplexObject command and many raycasting commands that have a wide variety of uses, including sliding collision.

I find math faster in this case than using sparky and less CPU intensive, however each user has is coding style.

Sparky is very good option too, like sixty squares says, his method can come in handy.
