Script resource

DaveTheCoder

I have a GDScript class that is not associated with a node.

I placed it in a .gd file, and the file header is:
class_name Polygon

It generally works. I can reference the class in other scripts, and it functions correctly. But I often get the error message:

The class "Polygon" couldn't be fully loaded (script error or cyclic dependency).

The documentation refers to "script resources", but isn't clear on how to create one. Would that be the solution for removing the error?

Maybe you could just use:
extends Resource

If no base class is given Reference is assumed. That works fine, if a Reference is what you want. The error indicates that you either have an error in the script or a cyclic reference. You will have to find this problem and fix it. Note that the editor sometimes keeps showing the error after it has been fixed. Closing and reopening all involved script files normally sorts that out.

The GDScript class is working as desired.

But it's simply a normal .gd file. Is there any reason why you would use a .tres file for a script, if that's even possible?

I appreciate the help. That fixed it. 😁

Huh? If you base you script on Resource your script is still a gd file.

Do you mean a resource file saved to disc? That is just an object of your custom class (the script). One of the additional features of resource over reference is that it can be serialised in this form (tres).
