Topics
	Distance Joint
	Functions for the distance joint.

	Motor Joint
	Functions for the motor joint.

	Mouse Joint
	Functions for the mouse joint.

	Filter Joint
	Functions for the filter joint.

	Prismatic Joint
	A prismatic joint allows for translation along a single axis with no rotation.

	Revolute Joint
	A revolute joint allows for relative rotation in the 2D plane with no relative translation.

	Weld Joint
	A weld joint fully constrains the relative transform between two bodies while allowing for springiness.

	Wheel Joint
	The wheel joint can be used to simulate wheels on vehicles.

Detailed Description

Joints allow you to connect rigid bodies together while allowing various forms of relative motions.

Enumeration Type Documentation

Joint type enumeration.

This is useful because all joint types use b2JointId and sometimes you want to get the type of a joint.
