Title: Collision detection for more than two objects?
Post by: KasHKoW on August 10, 2011, 10:14:04 pm

How would I make a collision detection for 2d objects for more than 2 objects.

As in 3 object collision or possibly more?

Pairwise?

If there are many objects (100 are not many), then testing collision for every pair of objects is not efficient. We have already discussed that here (http://www.sfml-dev.org/forum/viewtopic.php?t=5373)...

I know it's not efficient that's why i posted the question. What I want to know is how to detect collision with more than two objects all at the same time... Rather if it's a thousand or 3.

As I said, we've recently had that discussion. Read the linked thread, then you can still ask more specific questions ;)
