説明

Rigidbody オブジェクトの動きを制限させる際に使用します。

See Also: 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; }

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