卸载可释放 Unity 播放器所获取的内存,并使当前进程保持活动状态。
卸载可释放 Unity 播放器所获取的内存,并使当前进程保持活动状态。当 Unity 作为组件集成在其他应用程序中时(例如用于显示特定内容),这十分有用。当其他应用程序不再需要 Unity 时,可能要释放关联内存。
当前在 iOS、Android 和通用 Windows 平台上支持此功能。
在 iOS 和 Android 上,卸载会释放与场景和 GameObjects 相关的内存,但是会保留引擎所需的最小内存量。这样便可以在相同进程中再次运行 Unity。有关更多信息,请参阅有关针对 iOS 和 Android 将 Unity 作为库使用的文档。
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:此方法不会返回。
using UnityEngine; using System.Collections;
// Unload Unity when the user hits escape. Exit is not applied to the application.
public class ExampleClass : MonoBehaviour { void Update() { if (Input.GetKey("escape")) { Application.Unload(); } } }
