Error: godot could not resolve super class inheritance

What's Causing This Error

This error typically occurs when Godot's scripting system encounters a problem while trying to find the definition of a base class (superclass) that a script is supposed to inherit from. Causes can include:

  • The superclass script file has been moved, renamed, or deleted, breaking the file path reference in the subclass.
  • There are typos or incorrect case usage in the superclass name or file path.
  • The superclass script has errors preventing it from compiling, thus making it unavailable to any subclass.
  • If using GDNative or C#, the compiled library or assembly might not be updated or correctly linked.
  • File system permissions or issues that prevent reading the superclass script file.
  • Cyclic inheritance or other complex inheritance chains that confuse the engine.

Solution - Here's How To Resolve It

To fix this error, you should:

  1. Double-check the file path and name of the superclass script in the extends keyword at the top of your subclass script. Ensure there are no typos and that the case matches exactly, as Godot's file system is case-sensitive on some platforms.
  2. Verify that the superclass script exists at the specified path and that it is not missing or misnamed.
  3. Open the superclass script to ensure that it compiles successfully without errors.
  4. For GDNative or C# scripts, rebuild your native scripts or assemblies and make sure they are properly linked to your Godot project.
  5. Check the file permissions of the superclass script file to ensure that Godot has read access.
  6. Review your inheritance structure to rule out cyclic dependencies.
  7. If you recently upgraded your version of Godot, check the release notes for any changes in how Godot handles script inheritance that might affect your project.
  8. Restart Godot to clear any stale references or caches that might be causing the issue.

If these steps do not resolve the error, consider seeking help from the Godot community by providing specific details about your project's structure and any recent changes you've made.
