Agreed.
If you have to pass a CollisionEntity* around and you need to access say, bullet-specific data in the CollisionEntity, then you will have to do (dynamic_cast) downcasts regardless. You could do a switch statement like Haly suggested, or you could name your methods different things like HitBullet, HitPlayer, etc.
Thank you for your help though!

}It doesnt say the function has to be recursive.
But it's stupid regardless
And? As others have said its a horrible problem.
What happens when it calls sum(z-1)?
Oh, I guess I've just never used static local variables. Good to know, thanks.
As with all things, use where appropriate. It's certainly better than a global in most cases where you only need one instance.
