public static bool fullScreen ;


Is the game running full-screen?

It is possible to toggle full-screen mode by changing this property:

using UnityEngine;

public class Example : MonoBehaviour { void Start() { // Toggle fullscreen Screen.fullScreen = !Screen.fullScreen; } }

A full-screen switch does not happen immediately; it will actually happen when the current frame is finished.
