The tutorial for RPGs told me to call the enemy creation script “Spawn(InsertName)”, no return type, and a single parameter “room”. But it also told me to put it in the game start script, which lacks all of the things said above. Uhhhhhh..... what now?

No, you don't put it in the game start script. It goes in the on enter room description.

Can you provide the link to the RPG tutorial?
