Freeze rotation and motion along all axes.
//Attach this script to a GameObject with a Rigidbody. Press the up and down keys to move the Rigidbody up and down. //Press the space key to freeze all positions and rotations.

public class Example : MonoBehaviour { Rigidbody m_Rigidbody; Vector3 m_YAxis; float m_Speed;
void Start() { m_Rigidbody = GetComponent<Rigidbody>(); //Set up vector for moving the Rigidbody in the y axis m_YAxis = new Vector3(0, 5, 0); m_Speed = 20.0f; }
void Update() { //Press space to add constraints on the RigidBody (freeze all positions and rotations) if (Input.GetKeyDown(KeyCode.Space)) { //Freeze all positions and rotations m_Rigidbody.constraints = RigidbodyConstraints.FreezeAll; }
//Press the up arrow key to move positively in the y axis if the constraints are removed if (Input.GetKeyDown(KeyCode.UpArrow)) { //If the constraints are removed, the Rigidbody moves along the y axis //If the constraints are there, no movement occurs m_Rigidbody.velocity = m_YAxis; }
