Title: Programming a billard game
Post by: Roy301 on March 23, 2016, 07:38:37 pm

Hello,
I'm programming a litte billard game. I have the problem that i only know how to check for a collision between specific balls but i have already created a std::list for the balls. How can i  now check for collision between any balls in this list?

When checking collisions against balls in a list, the main problem ive encountered with this approach is that the ball you are checking will always be in collision with itself, so the first thing to do is remove the ball you are checking from the list, then iterate through said list checking against the balls in the list, then when you've done that, put the ball back in the list.
