JoinJail was made to create a sort of password protected server. We found that running a Minecraft server in offline mode made our whitelist not work properly. So I made this mod.
This mod generates a bedrock jail / holding place very very very far away from spawn. The only way to leave the jail is by using the set password. If a user dies in the jail they will spawn outside the jail but the first tick after spawning they will be back in the jail.
Usage
If you join a server with this mod you are required to enter the set password, this is done with the command:
/joinjail
/joinjail is the command and should be followed by the set password. If correct, you will be added to the whitelist and you can now always join.
Commands
- /joinjail setPassword
- This will set a new password
- /joinjail ban
- This will ban the selected player with the given reason. (This can be undone with the regular /pardon command)
