Does this serve any purpose, or is it just an overlooked side effect of copy/paste?
EDIT: After watching a later video where Ben gets an error for missing category on the Fire() method, I see now that it controls where they appear in the Blueprint node selector. My confusion was caused by a change that must’ve occurred in a more recent version of Unreal, where if no category is set, instead of producing an error, they are now placed in a default category named “Call Function”.
