Description

The JointMotor is used to motorize a joint.

For example the HingeJoint can be told to rotate at a given speed and force. The joint will then attempt to reach the velocity with the given maximum force.
See Also: HingeJoint.

using UnityEngine;

public class Example : MonoBehaviour { void Start() { HingeJoint hinge = GetComponent<HingeJoint>();

// Make the hinge motor rotate with 90 degrees per second and a strong force. JointMotor motor = hinge.motor; motor.force = 100; motor.targetVelocity = 90; motor.freeSpin = false; hinge.motor = motor; } }

Properties

forceThe motor will apply a force.
freeSpinIf freeSpin is enabled the motor will only accelerate but never slow down.
targetVelocityThe motor will apply a force up to force to achieve targetVelocity.
