"Class hides a global script class" script parsing issue about godot HOT 4 OPEN

When project is opened, Godot scans the filesystem and updates class cache. It's been made much more reliable recently. Previously some scripts could be missed because the scan was buggy.

You can add .gdignore file to your folder if you want to keep files, but have them ignored.

The problem is, that class_name classes that inherit node, get an entry in the create node dialogue. Also they could be used in every other script by their class name. In those cases there is no way to know which of your two scripts with the same class name is meant. Therefore class_names have to be unique across all scripts.

The class names are a unique identifier for a script so we need to know which script is meant, only given a class name. (Note, how this decision would have to be made before we could even say which scripts will run.)

Furthermore, we can't know which scripts are run with 100% certainty, since you can always use load to dynamically load and run a script. (Comes down to the halting problem. This could only be analyzed for a subset of all possible scripts, we can't rely on it therefore)

I see, but can you explain why this was previously not a problem in Godot 4.1.4? Was that just a bug?

Unused scripts are not fully loaded, but the editor checks their class_names and registers them with the ScriptServer. Then, when loading a script with the same class_name, GDScript generates an error.
