SceneManager.LoadScene

参数

描述

按照 Build Settings 中的名称或索引加载场景。

注意：在大多数情况下，为了避免在加载时出现暂停或性能中断现象， 您应该使用此命令的异步版，即： LoadSceneAsync。

When using this SceneManager.LoadScene, the loading does not happen immediately, it completes in the next frame. This semi-asynchronous behavior can cause frame stuttering and can be confusing because load does not complete immediately.

提供的 sceneName 可以只是场景名称（不包含 .unity 扩展名），也可以是 Build Settings 窗口中显示的路径（仍然不包含 .unity 扩展名）。如果仅提供场景名称，此方法将加载匹配的场景列表中的 第一个场景。如果您有多个名称相同但路径不同的场景， 应该使用完整的路径。

请注意，除非您从 AssetBundle 加载场景，否则 sceneName 不区分大小写。

如需在编辑器中打开场景，请参阅 EditorSceneManager.OpenScene。

    }
}

// Load an assetbundle which contains Scenes.
// When the user clicks a button the first Scene in the assetbundle is
// loaded and replaces the current Scene.
