A simple datapack that confines players to their own borders.
Note: The cords you define in the config file point to the block the player is allowed on, you cant go PAST that "border".
You can still interact with the environment the same, you just cant go outside the border.
IMPORTANT!: For it to work you have to configure the borders per player.
- Extract the file and go to data/personalborder/function/ and open init_config.mcfunction.
- There you copy the lines under "Copy this for every player" for every player.
- Then the last step is to change the usernames to the players and change the cords to the cords of the border you want. All 6 lines are neccesary for each player except if you dont want for example a north border.
