## Examples

```csharp
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.max = 90;
        limits.bounciness = 0;
        limits.bounceMinVelocity = 0;
        hinge.limits = limits;
    }
}

| ------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------- |
| [bounceMinVelocity](/engine/6000.7/script-reference/unityengine/jointlimits/bounceminvelocity.md) | The minimum impact velocity which will cause the joint to bounce.                                 |
| [bounciness](/engine/6000.7/script-reference/unityengine/jointlimits/bounciness.md)               | Determines the size of the bounce when the joint hits it's limit. Also known as restitution.      |
| [contactDistance](/engine/6000.7/script-reference/unityengine/jointlimits/contactdistance.md)     | Distance inside the limit value at which the limit will be considered to be active by the solver. |
| [max](/engine/6000.7/script-reference/unityengine/jointlimits/max.md)                             | The upper angular limit (in degrees) of the joint.                                                |
| [min](/engine/6000.7/script-reference/unityengine/jointlimits/min.md)                             | The lower angular limit (in degrees) of the joint.                                                |
