There are many things wrong with this question.
First, it’s not about collision detection (you can already detect when collisions happen), so your thread title is wrong.
Second, it is most certainly not advanced.
Third, it’s cross-posted from your thread on deleting display lists.
Fourth, it was already answered: stop drawing the things that aren’t supposed to be there anymore. This is not something difficult. If you understand how an if-statement works, then you can do it. And if you don’t, then you need more programming experience before doing graphics work.
You need a generic programming or game programming forum. this is not an OpenGL question, unless you are using the screen as a persistent framebuffer. If so please give more detail in the beginners forum.
I am locking this thread.
