Application.streamingAssetsPath

描述

StreamingAssets 文件夹的路径（只读）。

使用 StreamingAssets 文件夹来存储资源。在运行时，Application.streamingAssetsPath 提供文件夹路径。将资源名称添加到 Application.streamingAssetsPath。构建的应用程序即可加载此地址的资源。

无法访问 WebGL 和 Android 平台上的 StreamingAssets 文件夹。在 WebGL 上没有文件访问权。Android 使用压缩的 .apk 文件。这些平台返回 URL。请使用 UnityWebRequest 类来访问资源。
