b2WeldJointDef Struct Reference

#include <b2WeldJoint.h>

Inherits b2JointDef.

Public Member Functions
void	Initialize (b2Body *bodyA, b2Body *bodyB, const b2Vec2 &anchor)

Public Attributes
b2Vec2	localAnchorA
	The local anchor point relative to bodyA's origin.
b2Vec2	localAnchorB
	The local anchor point relative to bodyB's origin.
float32	referenceAngle
	The bodyB angle minus bodyA angle in the reference state (radians).
float32	frequencyHz
float32	dampingRatio
	The damping ratio. 0 = no damping, 1 = critical damping.
Public Attributes inherited from b2JointDef
b2JointType	type
	The joint type is set automatically for concrete joint types.
void *	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

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

Initialize the bodies, anchors, and reference angle using a world anchor point.
