How does collision detection work in C++ games?

Collision detection in C++ games involves checking if two or more objects intersect or collide. This can be done using various algorithms like bounding box checks, pixel-perfect collision, or physics engines.

What are the common algorithms used for collision detection?

Common algorithms include Axis-Aligned Bounding Box (AABB), Oriented Bounding Box (OBB), and spatial partitioning methods like quad-trees.

Can you explain how AABB works?

AABB checks if the bounding boxes of two objects overlap by comparing their minimum and maximum coordinates in each axis.

What libraries can I use for collision detection in C++?

You can use libraries like Box2D, Bullet Physics, or even game engines like Unity and Unreal Engine that have built-in collision detection.
