Field Documentation

cpBody* cpConstraint::a

The first body connected to this constraint.

cpBody* cpConstraint::b

The second body connected to this constraint.

cpDataPointer cpConstraint::data

User definable data pointer. Generally this points to your the game object class so you can access it when given a cpConstraint reference in a callback.

cpFloat cpConstraint::errorBias

The rate at which joint error is corrected. Defaults to pow(1.0 - 0.1, 60.0) meaning that it will correct 10% of the error every 1/60th of a second.

cpFloat cpConstraint::maxBias

The maximum rate at which joint error is corrected. Defaults to infinity.

cpFloat cpConstraint::maxForce

The maximum force that this constraint is allowed to use. Defaults to infinity.

cpConstraintPostSolveFunc cpConstraint::postSolve

Function called after the solver runs. Use the applied impulse to perform effects like breakable joints.

cpConstraintPreSolveFunc cpConstraint::preSolve

Function called before the solver runs. Animate your joint anchors, update your motor torque, etc.
