Application.CancelQuit

Description

Cancels quitting the application. This is useful for showing a splash screen at the end of a game.

This function only works in the player. IMPORTANT: This function has no effect on iPhone. Application can not prevent termination under iPhone OS.

	// Delays quitting for 2 seconds and
	// loads the finalsplash level during that time.

	var showSplashTimeout : float = 2.0;
	private var allowQuitting : boolean = false;

	function Awake () {
		// This game object needs to survive multiple levels
		DontDestroyOnLoad (this.gameObject);
	}

	function OnApplicationQuit () {
		// If we haven't already load up the final splash screen level
		if (Application.loadedLevelName.ToLower() != "finalsplash")
			StartCoroutine("DelayedQuit");

		// Don't allow the user to exit until we got permission in
		if (!allowQuitting)
			Application.CancelQuit();
	}

	function DelayedQuit () {
		Application.LoadLevel("finalsplash");

		// Wait for showSplashTimeout
		yield WaitForSeconds(showSplashTimeout);

		// then quit for real
		allowQuitting = true;
		Application.Quit();
	}
