Freeze rotation along the X-axis.

//This example shows how RigidbodyConstraints is used to freeze the position and rotation of a Rigidbody in the x axis at start-up.
//It also shows what happens when these constraints are removed, when you press the space key
//Attach this to a GameObject with a Rigidbody to see it in action

using UnityEngine;

public class Example : MonoBehaviour { Rigidbody m_Rigidbody; Vector3 m_XAxis;

void Start() { m_Rigidbody = GetComponent<Rigidbody>(); //This locks the RigidBody so that it does not move or rotate in the x axis (can be seen in Inspector). m_Rigidbody.constraints = RigidbodyConstraints.FreezePositionX | RigidbodyConstraints.FreezeRotationX; //Set up vector for moving the Rigidbody in the x axis m_XAxis = new Vector3(5, 0, 0); }

void Update() { //Press space to remove the constraints on the RigidBody if (Input.GetKeyDown(KeyCode.Space)) { //Remove all constraints m_Rigidbody.constraints = RigidbodyConstraints.None; }

//Press the right arrow key to move positively in the x axis if the constraints are removed if (Input.GetKeyDown(KeyCode.RightArrow)) { //If the constraints are removed, the Rigidbody moves along the x axis //If the constraints are there, no movement occurs m_Rigidbody.velocity = m_XAxis; }

//Press the left arrow key to move negatively in the x axis if the constraints are removed if (Input.GetKeyDown(KeyCode.LeftArrow)) { m_Rigidbody.velocity = -m_XAxis; } } }
