Смотрите так же: Rigidbody.constraints. This enables you to freeze positions and rotations on all axes.
//This example shows how RigidbodyConstraints is used to freeze the position and rotation of a Rigidbody in the z 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 RigidBodyConstraitsExample : MonoBehaviour
{
Rigidbody m_Rigidbody;
Vector3 m_ZAxis;
void Start()
{
m_Rigidbody = GetComponent<Rigidbody>();
//This locks the RigidBody so that it does not move or rotate in the z axis (can be seen in Inspector).
m_Rigidbody.constraints = RigidbodyConstraints.FreezePositionZ | RigidbodyConstraints.FreezeRotationZ;
//Set up vector for moving the Rigidbody in the z axis
m_ZAxis = new Vector3(0, 0, 5);
}
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 z axis if the constraints are removed
if (Input.GetKeyDown(KeyCode.RightArrow))
{
//If the constraints are removed, the Rigidbody moves along the z axis
//If the constraints are there, no movement occurs
m_Rigidbody.velocity = m_ZAxis;
