I've been reading up all day and i've tried to implement it in various fashions but i can't seem to append to my config file correctly. This is my config Code: Items-Locked: Location: x: 148 y: 67 z: 394 key: AIR I'm simple trying to make it so that i can add multiple locations. Their names being just Location2 and so forth. The guides i've read up on suggested using a List and grabbing the "Items-Locked" and then adding to it. However once I grabbed the list and added to it there was nothing in it. Anybody have a tip for adding to a config file? tl:dr Goal is to add a new key [location2..3..etc and values(x,y,z,key).
