b2MouseJointDef Struct Reference

#include <b2MouseJoint.h>

Inherits b2JointDef.

Public Attributes
b2Vec2	target
float32	maxForce
float32	frequencyHz
	The response speed.
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

Mouse joint definition. This requires a world target point, tuning parameters, and the time step.

Member Data Documentation

float32 b2MouseJointDef::maxForce

The maximum constraint force that can be exerted to move the candidate body. Usually you will express as some multiple of the weight (multiplier * mass * gravity).

b2Vec2 b2MouseJointDef::target

The initial world target point. This is assumed to coincide with the body anchor initially.
