HingeJoint.limits

Description

Limit of angular rotation (in degrees) on the hinge joint.

The joint will be limited so that the angle is always between JointLimits.min and JointLimits.max. The joint angle is in degrees relative to the rest angle. The rest angle between the bodies is always zero at the beginning of the simulation.

Additional resources: useLimits, JointLimits.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Start()
    {
        // Set the hinge limits for a door.
        HingeJoint hinge = GetComponent<HingeJoint>();

        JointLimits limits = hinge.limits;
        limits.min = 0;
        limits.bounciness = 0;
        limits.bounceMinVelocity = 0;
        limits.max = 90;
        hinge.limits = limits;
        hinge.useLimits = true;
    }
}

Modifying the limits does not automatically enable the limits.
