Which one is more accurate?

Which one is more accurate for collison detection?

CameraPick, EntityPick, LinePick ?!?

entityPick I would guess. But it would only give one object at a time I think...

accuracy is subjective.
they do different things:

CameraPick ( camera,viewport_x#,viewport_y# )

EntityPick ( entity,range# )

LinePick ( x#,y#,z#,dx#,dy#,dz#[,radius#] )

however,

line pick has more definable attributes and therefore could be considered moe accurate.

actually, what kind of collision detection are you thinking of doctor? Is this to speed up collision detection by only checking nearby objects, or something else?

Actually!! Im' needing it for shooting enemies with a gun!
I just wanted to know which one would be the best route to use for this?

I think there's a demo of how to do that in the samples folder of Blitz3D. It's called FPS or somehing....

One, constant linepick would be all you need for your gun. When the gun is fired, the enemy that has been picked, by the linepick, is shot.
