MonoBehaviour.OnApplicationFocus(bool)

Switch to Manual

Description

Sent to all game objects when the player gets or loses focus.

OnApplicationFocus can be a co-routine, simply use the yield statement in the function. If it is implemented as a coroutine, it will be evaluated twice during the initial frame: first as an early notification and second time during the normal coroutine update step.

	var paused: boolean;

function OnGUI() { // Show a message if the game is paused. if (paused) { GUI.Label(new Rect(100, 100, 50, 30), "Game paused"); } }

function OnApplicationFocus(focusStatus: boolean) { paused = focusStatus; }

using System.Collections;

    public bool paused;
    void OnGUI() {
        if (paused)
            GUI.Label(new Rect(100, 100, 50, 30), "Game paused");
