Public Attributes inherited from b2JointDef
b2JointType	type
	The joint type is set automatically for concrete joint types.
b2JointUserData	userData
	Use this to attach application specific data to your joints.
b2Body *	bodyA
	The first attached body.
b2Body *	bodyB
	The second attached body.
bool	collideConnected
	Set this flag to true if the attached bodies should collide.

Detailed Description

Weld joint definition. You need to specify local anchor points where they are attached and the relative body angle. The position of the anchor points is important for computing the reaction torque.

Member Function Documentation

Initialize()

void b2WeldJointDef::Initialize	(	b2Body *	bodyA,
		b2Body *	bodyB,
		const b2Vec2 &	anchor
	)

Initialize the bodies, anchors, reference angle, stiffness, and damping.

Parameters

bodyA	the first body connected by this joint
bodyB	the second body connected by this joint
anchor	the point of connection in world coordinates
