MotorJoint

Constraint → nape.constraint.MotorJoint (final class)

MotorJoint constraining the angular velocities of two bodies

The equation for this constraint is:

(ratio * body2.angularVel) - body1.angularVel = rate

This constraint operates only on the velocities of objects.

Instance Members

nape

zpp_inner_zn: zpp_nape.constraint.ZPP_MotorJoint

@private

nape

body1: Null<nape.phys.Body>

First Body in constraint.

This value may be null, but trying to simulate the constraint whilst this body is null will result in an error.

nape

body2: Null<nape.phys.Body>

Second Body in constraint.

This value may be null, but trying to simulate the constraint whilst this body is null will result in an error.

nape

ratio: Float

MotorJoint ratio.

@default 1

nape

rate: Float

MotorJoint rate

@default 0

nape

impulse(): nape.geom.MatMN

@inheritDoc

For this constraint, the MatMN will be 1x1.

Returns
nape.geom.MatMN

nape

bodyImpulse(body: nape.phys.Body): nape.geom.Vec3

@inheritDoc

For this constraint, only the z coordinate will be non-zero.
