4.6.1
I created a script where I declared several signals and in another script I am trying to refer to that script to use the signals and am getting the error “Identifier “CommandDispatcher” not declared in the current scope.” What am I doing wrong? I’m following a tutorial step-by-step and the guide had no issues when they did it this way.
There should be
class_name CommandDispatcher
at the beginning of your CommandDispatcher.gd script.
That seems to have changed the error but now I’m getting
“Cannot find member “PROCESS_COMMAND” in base “CommandDispatcher”.
I see, then probably what you want is an autoload, not a class. In this case forget what I mentioned and read through this article:
This solved it!
Would you mind explaining why simply having it as a class wouldn’t work? If not that’s ok, I’m just still learning.

When you have defined a class CommandDispatcher and then you write CommandDispatcher.PROCESS_COMMAND, you request a static property of the class. We don’t have static signals in GDScript currently (see proposal #6851), that’s why it fails.
When you define an autoload, it’s a bit special case which looks the same as if it were declared as a class, but it’s actually an instance that you can refer to as CommandDispatcher. Then when you write CommandDispatcher.PROCESS_COMMAND, you request a property of the instance, a signal in this case, which is perfectly valid.
Thank you! This is very helpful. I appreciate you taking the time to educate me.
