| class | b2Joint |
A weld joint essentially glues two bodies together. A weld joint may distort somewhat because the island constraint solver is approximate.
| void b2WeldJoint::Dump | ( | ) | [virtual] |
Dump to b2Log.
Reimplemented from b2Joint.
| b2Vec2 b2WeldJoint::GetAnchorA | ( | ) | const [virtual] |
Get the anchor point on bodyA in world coordinates.
Implements b2Joint.
| b2Vec2 b2WeldJoint::GetAnchorB | ( | ) | const [virtual] |
Get the anchor point on bodyB in world coordinates.
Implements b2Joint.
| const b2Vec2& b2WeldJoint::GetLocalAnchorA | ( | ) | const [inline] |
The local anchor point relative to bodyA's origin.
| const b2Vec2& b2WeldJoint::GetLocalAnchorB | ( | ) | const [inline] |
The local anchor point relative to bodyB's origin.
| b2Vec2 b2WeldJoint::GetReactionForce | ( | float32 | inv_dt | ) | const [virtual] |
Get the reaction force on bodyB at the joint anchor in Newtons.
Implements b2Joint.
| float32 b2WeldJoint::GetReactionTorque | ( | float32 | inv_dt | ) | const [virtual] |
