Root Cause

The specified path inside a package does not exist, often because the resource was not placed in a 'Resources' folder within the package, or the package is not properly imported.

中文

包内指定的路径不存在，通常是因为资源未放置在包内的“Resources”文件夹中，或者包未正确导入。

Workarounds

  1. 90% success Ensure the resource is inside a 'Resources' folder within the package. For example, create the folder structure: `Packages/com.example.custompackage/Resources/MyAsset.asset`. Then use `AssetDatabase.LoadAssetAtPath<ScriptableObject>("Packages/com.example.custompackage/Resources/MyAsset.asset")`.

中文步骤

  1. 确保资源位于包内的“Resources”文件夹中。例如，创建文件夹结构：`Packages/com.example.custompackage/Resources/MyAsset.asset`。然后使用 `AssetDatabase.LoadAssetAtPath<ScriptableObject>("Packages/com.example.custompackage/Resources/MyAsset.asset")`。
  2. 如果包是本地包，则使用相对项目根目录的路径，例如 `Assets/MyResources/MyAsset.asset`，而不是包路径。
  3. 验证包是否已正确安装并在项目窗口的“包”下可见。如果不可见，请通过包管理器重新安装包。

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Moving the resource to a different folder within the package without using a 'Resources' folder will still fail because AssetDatabase.LoadResourceAtPath only searches 'Resources' folders.

  2. 90% fail

    Reimporting the package does not help if the resource path is incorrect or the folder structure is wrong.
