I apologize for asking what I would imagine to be a simple question, but I spent a good 20 minutes searching for the answer.
It seems that there is an official way to make functions, but in the tutorials I found it doesn't actually show me how specifically, and as far as I can actually tell by fiddling around with event sheets, there isn't an actual way to make functions officially in C2. Is such a simple time saving ability not implemented into C2 or am I just looking in the wrong places?
