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.
