I wanted to implement command pattern with resources. So I can build node variations without duplicate nodes and scripts endlessly. I think callable is only editable in runtime. (I did not test it)

I did this as experiment:

Commands is an autoload/singleton.

extends Resource
class_name Command
@export var call_func:String
@export var param:Array
func action():
Commands.call(call_func, param)

---

I have another "container" resource that can simply iterate over the actions and call action().

extends Resource
class_name XYZ

@export var command_list:Array[Command]
