Hi dear
I try to develop a new game in c# with XNA.
you know that in game we should check collision between objects in each time. but when we create too many object, collision detection is very harmful for my project because it take too much time.
I googled it so i found that i have to use neighbor list to reduce check counts.
can u help me or did you saw this code already.
best regard

Solution 1

Actually what I think you are looking for is Binary Space Partitioning (BSP) trees. They are a tried-and-true method for finding objects that are near other objects, which will cut down on your collision detection code.

Solution 2

Software development is done not by "seeing" "this code", but by writing code, which is performed by using developer's brain.

Good luck,
