## 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.

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

## Member Data Documentation

## ◆ stiffness

float b2WeldJointDef::stiffness

The rotational stiffness in N*m Disable softness with a value of 0
