MonoBehaviour.OnApplicationFocus(bool)

Descripción

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.Implemented this way, it will be evaluated twice during the initial frame: first as an early notification and second time during the normal coroutine update step.

On Android, when the on-screen keyboard is enabled, it will cause OnApplicationFocus( false ) event. Also, if you press "home" at the moment the keyboard is enabled, the OnApplicationFocus() event won't get called, but OnApplicationPause() will be called instead.

using UnityEngine;


public class AppPaused : MonoBehaviour
{
	bool isPaused = false;


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

	void OnApplicationFocus( bool focusStatus )
	{
		isPaused = focusStatus;
	}

	void OnApplicationPause( bool pauseStatus )
	{
		isPaused = pauseStatus;
	}
}
