Detailed Description

A weld joint fully constrains the relative transform between two bodies while allowing for springiness.

A weld joint constrains the relative rotation and translation between two bodies. Both rotation and translation can have damped springs.

Note: The accuracy of the weld joint is limited by the accuracy of the solver. Long chains of weld joints may flex.

Data Structure Documentation

struct b2WeldJointDef

Weld joint definition Connects two bodies together rigidly.

This constraint provides springs to mimic soft-body simulation.

Note: The approximate solver in Box2D cannot hold many bodies together rigidly

Data Fields
float	angularDampingRatio	Angular damping ratio, non-dimensional. Use 1 for critical damping.
float	angularHertz	Angular stiffness as Hertz (cycles per second). Use zero for maximum stiffness.
b2JointDef	base	Base joint definition.
int	internalValue	Used internally to detect a valid definition. DO NOT SET.
float	linearDampingRatio	Linear damping ratio, non-dimensional. Use 1 for critical damping.
float	linearHertz	Linear stiffness expressed as Hertz (cycles per second). Use zero for maximum stiffness.

b2JointId b2CreateWeldJoint	(	b2WorldId	worldId,
		const b2WeldJointDef *	def )

Create a weld joint.
