I was looking at the rts thread and I was thinking about the battles in rts games. I was thinking that there must be a better way of testing collisions. I think a lot of people use a dual loop to test all the collisions. I was thinking how slow it would be in an rts game to use a loop to find collisions. I was wondering if any one has came up with a better way of testing multiple collisions. I have a theory and was woudering what are your thoughts on mass collisions.
