Chipmunk2D is a fast, lightweight 2D rigid body physics library written in C99 with no external dependencies. It provides collision detection, impulse solving, joints, raycasting queries, and collision callbacks designed specifically for 2D video games.

Use cases

• add physics to a 2d game
• simulate rigid bodies with collisions
• implement ragdolls and vehicles with joints
• raycast and shape queries in a 2d world
• build one-way platforms and buoyancy zones
• embed a lightweight physics engine in a C or C++ project

When to choose

• you need a fast, dependency-free 2D physics engine in C
• you are building a 2D game and want mature, MIT-licensed physics
• you need language bindings, as many exist for Chipmunk2D

When to avoid

• you need 3D physics simulation
• you prefer a batteries-included game engine rather than a physics library
• you need GPU-accelerated or heavily multithreaded physics beyond its built-in multithreaded solver
