How does physics work in a C++ game engine?

Physics in a C++ game engine typically involves simulating real-world forces and interactions using algorithms.

What are the common physics engines used in C++?

Common physics engines include Bullet, PhysX, and Box2D, each with unique features for different types of games.

Can you explain how collision detection works?

Collision detection involves checking if two objects intersect, often using bounding boxes or more complex shapes.

What role does gravity play in game physics?

Gravity affects how objects fall and interact, simulating a realistic environment by applying a downward force.

How can I optimize physics calculations in my game?

You can optimize by reducing the number of active physics objects, using simpler collision shapes, and implementing spatial partitioning.
