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.
 
b2BodybodyA
 The first attached body.
 
b2BodybodyB
 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.

Member Data Documentation

float32 b2WeldJointDef::frequencyHz

The mass-spring-damper frequency in Hertz. Rotation only. Disable softness with a value of 0.
