How does collision detection work in C++ game development?

Collision detection in C++ involves checking if two or more objects intersect in a game environment. This can be done using bounding boxes, circles, or more complex shapes.

What are the common algorithms used for collision detection?

Common algorithms include Axis-Aligned Bounding Box (AABB), Separating Axis Theorem (SAT), and Spatial Partitioning methods like Quadtrees.

Can you explain how AABB works?

AABB checks for collisions by comparing the minimum and maximum coordinates of two rectangles. If they overlap in both x and y axes, a collision is detected.

What about performance optimization for collision detection?

To optimize performance, you can use spatial partitioning, reduce the number of checks with broad-phase collision detection, and implement layers to ignore certain collisions.
