CursorLockMode.None

Description

Cursor behavior is unmodified.

//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"))
