collision-detection

Hi,

I am looking for a good method to determine which objects will be considered for collision with other objects.

My current idea is that each object has the following properties:

alwaysCollidesWith = [list of objects that will always trigger a collision check] neverCollidesWith = [lost of objects that will never be considered] teamCollidesWith = [list of objects that will be checked, provided they belong to a different team]

For example: -projectiles never have to be checked for collisions with other projectiles -players are always checked for collisions with players, regardless of team -projectiles are only considered for collisions if they collide with another teams players

Does anyone see any weaknesses with this approach? Can anyone recommend a better approach?
