本页将介绍在批处理模式下运行 Unity Editor 和独立平台播放器 (Standalone Player) 时支持的功能。

运行 Unity 时，以下内置 协程 运算符可添加功能：

AsyncOperation

WaitForEndOfFrame

WaitForFixedUpdate

WaitForSeconds

WaitForSecondsRealtime

WaitUntil

WaitWhile

下表显示了 Unity 在 Editor 和独立平台播放器中支持的运算符，还包括使用 -batchmode 命令行参数以批处理模式运行两者时的运算符支持情况：

* 使用 -batchmode 运行 Editor 时，不能使用 WaitForEndOfFrame ，因为动画、物理和时间轴等系统可能无法在 Editor 中正常工作。这是因为 Unity 在使用 WaitForEndOfFrame 时当前不会更新这些系统。

在 Editor 中

在 Editor 中，按下“Play”按钮以使用协程运行代码。

批处理模式下的 Editor

要在以批处理模式启动 Editor 时从命令行运行协程，请输入：

C:\Program Files\Unity\Editor\Unity.exe -projectPath PROJECT_PATH -batchMode

在独立平台播放器中

启动独立平台播放器以运行您的代码。播放器会加载，然后等待协程完成。

批处理模式下的独立平台播放器

要在以批处理模式启动播放器时从命令行运行协程，请输入：

PATH_TO_STANDALONE_BUILD -projectPath PROJECT_PATH -batchMode

例如，在 Windows 上：

C:\projects\myproject\builds\myproject.exe -batchMode

在 Mac 上：

~/UnityProjects/myproject/builds/myproject -batchMode

协程脚本示例
