移動させない

//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.

using UnityEngine;

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

void Start() { m_Rigidbody = GetComponent<Rigidbody>(); //Set up vector for moving the Rigidbody in the y axis m_YAxis = new Vector3(0, 5, 0); }

void Update() { //Press space to add constraints on the RigidBody (Freezing the position) if (Input.GetKeyDown(KeyCode.Space)) { //Freeze all positions m_Rigidbody.constraints = RigidbodyConstraints.FreezePosition; }

//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; }

//Press the down arrow key to move negatively in the y axis if the constraints are removed if (Input.GetKeyDown(KeyCode.DownArrow)) { m_Rigidbody.velocity = -m_YAxis; } } }
