How do Unity manages collisions in a game internally?
If I've got a thousand game objects with colliders in a scene, does Unity check all possible pairs for collisions or does it use some kind of optimization?
What if I only use OnCollisionEnter() in one of those thousand gameobjects? Does it only check that one or does it check all of them for possible collisions?
I want to make an awesome Bullet Hell :D nad I want to know if I need to implement some kind of optimization of my own. Thank you for your wise answers
