Application.wantsToQuit

描述

Unity raises this event when the Player application wants to quit.

向此事件添加一个事件处理程序，以便接收关于应用程序试图退出的通知。

引发此事件时，退出过程已开始但可以取消。这意味着播放器并不保证退出。有关保证退出事件，请查看 Application.quitting。

Returns true and the quit process continues. Returns false and the quit process cancels.

Note: The return value of this event is ignored when exiting Play mode in the Editor.

Important: The return value has no effect on iOS or iPadOS. The Application._wantsToQuit can't prevent termination in iOS or iPadOS.

using UnityEngine;

public class PlayerWantsToQuitExample
{
    static bool WantsToQuit()
    {
        Debug.Log("Player prevented from quitting.");
        return false;
    }

    [RuntimeInitializeOnLoadMethod]
    static void RunOnStart()
    {
        Application.wantsToQuit += WantsToQuit;
    }
}
