# Made by ChavitaHD

options:

# Here is the option to support this in only specific worlds. To add worlds, make sure you have double quotes around the world name. Also remember that the word "or" seperates them. As an example below, it's set as: "world_prison" or "worldnamehere"
    WORLD: "world_prison" or "worldnamehere"

# I don't recommend you edit this unless you know what you're doing. I added 1 extra line that allows the skript to work only in the specific world(s). Make sure to add some more above ^
