I am having trouble determining what object gets hit first by the bullet when it is shot. I use really long 3d boxes as bullets, but the problem comes when they intersect 2 objects. This would be fine, unless the enemy that gets hit is in a building. The bullet should hit the wall, but the only way of referencing proximity to the shooter is by each object position. But the position of the structure is farther away than the enemies. If you don't understand, here is a drawing:

+ Code Snippet

                  ____________________________________________
  o              /   o                                        |
  +-----BULLET---|-->+                   +(position           |
  /             |___/__________________of building)__________|
  Shooter            enemy

So, as you can (hopefully) see from my really bad representation, the enemies position is closer than the building's but the wall should get hit first.

If anyone has a better way of fps shooting, that is greatly appreciated.

Using raycasting for collision would make bullet collision much easier. It also solves the problem you described above because raycasting will give you the object that the polygon the ray collides with belongs to. I suggest using Sparky's DBC Collision Dll because the command are simple, east to use, and work relatively fast.
