19.10 Constraints

All Constraints share common accessors.

Accessors	Type	Description
bodyA	physics.Body	The first Body that the Constraint acts on
bodyB	physics.Body	The second Body that the Constaint acts on
setBiasCoef, biasCoef	number	The fraction of error corrected each step of the simulation. Defaults to 0.1. May not behave as expected for numbers larger than 1.0 or less than 0.
setData, data	Lua object	A programmer-defined object
impulse	number	Calculated impulse applied by the Constraint in the last simulation step. To convert this to the magnitude of the force, divide by the time step passed to physics.Space:step()
setMaxBias, maxBias	number	Maximum speed the Constraint can apply error correction. Defaults to INFINITY
setMaxForce, maxForce	number	Magnitude of maximum force the Constraint can use to act on the two Bodies. Defaults to INFINITY
