I want to have 4 NPCs or so who will fight along with the player in my game. Is there a way to create a Monster with CombatLib who will befriend the player and fight with him? I have looked up this set of instructions...

...but I can't figure out how or where to access this list (game.friends). I did Ctrl-F and searched for it in the code view of my game, and also in CombatLib, but I just don't see where I should plug it in.
