Controls which degrees of freedom are allowed for the simulation of this Rigidbody.
By default this is set to RigidbodyConstraints.None, 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.
Note that position constraints are applied in World space, and rotation constraints are applied in Local space.
//Attach this script to a GameObject. //Attach a Rigidbody to the GameObject by clicking the GameObject in the Hierarchy and //clicking the Add Component button. Search for Rigidbody in the field and select //it when shown.
using UnityEngine;
public class Example : MonoBehaviour { Rigidbody m_Rigidbody;
void Start() { m_Rigidbody = GetComponent<Rigidbody>(); //This locks the RigidBody so that it does not move or rotate in the Z axis. m_Rigidbody.constraints = RigidbodyConstraints.FreezePositionZ | RigidbodyConstraints.FreezeRotationZ; } }
