About this Mod
About
Get notified when a player is within your loaded chunks. Fully client-side.
You can choose between a chat message, a message above the hotbar, and/or a sound indicator.
It is highly recommended you install MidnightLib, as the config will NOT WORK without MidnightLib installed.
Commands
To prevent some players from being picked up in the radar, or to only make specific players get picked up, use /radarlist. The usage is:
/radarlist add <player>- Add a player to the list by their username./radarlist remove <player>- Remove a player from the list by their username./radarlist mode- Returns the current radar mode./radarlist mode (blacklist|whitelist)- Sets the current radar mode./radarlist uuid add <uuid>- Add a player to the list by their UUID./radarlist uuid remove <uuid>- Remove a player from the list by their UUID./radarlist toggle- Toggles the radar on or off.
Using blacklist mode will prevent any user in the list from being detected.
Using whitelist mode will only allow users in the list to be detected.
The whitelist and blacklist are two separate lists; they do not share the same data.
WARNING
Some servers may consider this a cheat or a hack. I do not encourage hacking. Please check with your server owner or a moderator before using this mod.
