Application.Unload

描述

Unloads the Unity Player.

Unity triggers an Application.unloading event and releases memory acquired by the Unity Player while keeping the current process alive. The amount of memory that is released depends on the platform. This is useful when Unity is integrated into another application (see Unity as a Library as its component (for example, to display 2D/3D/AR content). When the application doesn't need content displayed by Unity anymore, you can release the associated memory by calling this method.

当前在 iOS、Android 和通用 Windows 平台上支持此功能。

On iOS and Android, Unload releases memory used by Scenes and GameObjects, but reserves some memory which is necessary for running Unity in the same process again. To learn more, see documentation on Unity as a Library for iOS and Android.

在通用 Windows 平台上，卸载 Unity 运行时并释放所有引擎内存。这与退出类似，只不过应用程序进程不会退出。

**注意：**此函数不会返回值。

using UnityEngine;
using System.Collections;

// Unload Unity when the user clicks the button. Exit is not applied to the application.

public class ExampleClass : MonoBehaviour
{
    void OnGUI()
    {
        if (GUI.Button(new Rect(10, 10, 200, 75), "Unload"))
            Application.Unload();
    }

    static void OnUnload()
    {
        Debug.Log("Unloading the Player");
    }

    [RuntimeInitializeOnLoadMethod]
    static void RunOnStart()
    {
        Application.unloading += OnUnload;
    }
}
