var constraints : RigidbodyConstraints

Description

Controls which degrees of freedom are alowed for the simulation of this Rigidbody.

By default this is RigidbodyConstraints.FreezeNone, allowing rotation and movement along all axes. In some cases, you may want to constrain a Rigidbody to only move or rotate along some axes, for example when developing 2D games. You can use the bitwise OR operator to combine multiple constraints.

// Freeze the rotation around x-Axis
rigidbody.constraints = RigidbodyConstraints.FreezeRotationX | RigidbodyConstraints.FreezeRotationY;

using UnityEngine;
using System.Collections;

public class example : MonoBehaviour {
    void Example() {
        rigidbody.constraints = RigidbodyConstraints.FreezeRotationX | RigidbodyConstraints.FreezeRotationY;
    }
}

    def Example():
        rigidbody.constraints = (RigidbodyConstraints.FreezeRotationX | RigidbodyConstraints.FreezeRotationY)
