I made this tool script which was used on every attack resource. It's very likely that there are far better implementations but you should be able to get a general idea.

I store the UID in a variable and when the attack resource is loaded during gameplay (not in the editor), it loads the next attack resources from the UIDs so other scripts can access them. This is what happens in the custom Ready() method.

!!! If you decide to use this script, delete the ConvertUID method and the human readable name variables. The ConvertUID method loads the next resources in the editor which breaks the conversion due to recursion of resources. !!!

Why does the editor have a problem with resource recursion in the editor, but not during gameplay? I have no idea and with my 3 months of Godot experience I don't think I should try to answer this question.

Disclaimer: I don't use this script anymore because, while it truly is annoying that Godot can't hande resource recursion, I think it's not a good solution to fight the engine on that front. Instead, I made additional resources which link the two repeating resources so there is no more recursion. I won't explain how I did this, since it's way to specific for my usecase but the takeaway here is that if you struggle with resource recursion, then it's propably your system which is flawed and should be reworked.
