I figured this is would be the correct place to ask the following ...

1. How would I go about making multiple object collision detection (Bullets For Example)?

2. How would I make it efficient enough so that I can have many objects be able to detect the other objects collision

The only idea I currently have is for each bullet to iterate through the other game objects and check collision individually. But that could/would have a terrible impact on time, considering that there can be many objects in the scene. Any Suggestions?

I have also considered multi threading, but I really don't know how to apply it in game programming. Any Suggestions?
