Available since LÖVE 0.4.0
This module is not supported in earlier versions.

Can simulate 2D rigid bodies in a realistic manner. This module is essentially just a binding to Box2D (version 2.3.0 - manual).

For simpler (and more common) use cases, a small number of libraries exist, which are usually more popularly used than love.physics and can be found here:


Body Bodies are objects with velocity and position.
Contact Contacts are objects created to manage collisions in worlds.
Fixture Fixtures attach shapes to bodies. Added since 0.8.0
Joint Attach multiple bodies together to interact in unique ways.
Shape Shapes are objects used to control mass and collisions.
World A world is an object that contains all bodies and joints.
