CursorLockMode.Locked

説明

Locks the cursor to the center of the Game view.

CursorLockMode.Locked also hides the hardware cursor. However, the cursor is only locked and hidden after you click in the Game view.

//This script makes Buttons that control the Cursor's lock state. Note that the Confined mode only works on Windows and Linux Standalone platform build.

using UnityEngine;

public class Example : MonoBehaviour
{
    void Update()
    {
        //Press the space bar to apply no locking to the Cursor
        if (Input.GetKey(KeyCode.Space))
            Cursor.lockState = CursorLockMode.None;
    }

    void OnGUI()
    {
        //Press this button to lock the Cursor
        if (GUI.Button(new Rect(0, 0, 100, 50), "Lock Cursor"))
        {
            Cursor.lockState = CursorLockMode.Locked;
        }

        //Press this button to confine the Cursor within the screen
        if (GUI.Button(new Rect(125, 0, 100, 50), "Confine Cursor"))
        {
            Cursor.lockState = CursorLockMode.Confined;
        }
    }
