Description 描述

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

当玩家获得或失去焦点时发送给所有游戏对象。

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.

OnApplicationFocus 可以作为协同程序，在函数中简单使用yield状态。如果作为协同执行，它将在初始帧中再次被计算：首先作为一个早期的通知，第二次在正常协同更新步骤。

JavaScript:

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; 
} 

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public bool paused;
    void OnGUI() {
        if (paused)
            GUI.Label(new Rect(100, 100, 50, 30), "Game paused");
 
    }
    void OnApplicationFocus(bool focusStatus) {
        paused = focusStatus;
    }
}
