Build Item

Packaging Your Item

Once you've finished editing your item, you can try packaging it. Before you begin, ensure that all necessary information for the item in the Item Manager window is set correctly.

Click the Build button in the Item Manager window. The packaged content will be stored in a folder with the same name as the item under the [Project Root Directory]/Export/Items directory.

If any warnings or errors occur during packaging, check the Console window for more information.

Common Errors in the Console Window During Packaging

Error: 'Can't build custom scripts with warning: The C# source file 'XXX.cs' exists in the Unity project but not in the .csproj file and will not be compiled. You may need to regenerate the script project file/Script compilation will be skipped. No source files were specified! Possible Reason: The script editor failed to generate the correct csproject.'

Solution: Ensure that the Packages Manager window contains a unique script editor and that it matches the settings in the Preferences window under External Tools (e.g., Visual Studio):

Notes:

• During packaging, scene or Prefab files in the Item folder will be temporarily modified. If the packaging process fails due to special reasons, these files may not be restored. Therefore, make backups before packaging.
• Due to AssetBundle limitations, scene names within the Item folder must be unique; otherwise, packaging will fail.
