Xaero’s Map Server Utils Data Pack FAQ
10 questions players actually ask, answered.
How do I install this data pack on my server?
Place the data pack folder into your world's datapacks directory, then run /reload or restart your server. You'll know it's loaded when you can run /function xaero:fairxaero without errors.
What's the difference between fairxaero and nominimap?
/function xaero:fairxaero disables only cave mode and mob radar while keeping the minimap visible, whereas /function xaero:nominimap removes the entire minimap interface from all players.
Can I let players use cave maps in the Nether but not the Overworld?
Yes—run /function xaero:fairxaero to disable caves everywhere, then run /function xaero:xaerowmnetherisfair to re-enable cave viewing specifically in the Nether.
How do I make map restrictions apply automatically when players join?
Use /function xaero:autorun/set/fairxaero (or whichever restriction you want) to set it as the auto-run function, and it will execute every time a player logs in.
Can I hide the command messages from appearing in chat?
Yes—use the silent versions like /function xaero:silent/fairxaero instead of the regular command to apply restrictions without broadcasting notifications to the server.
What happens if I run multiple restriction functions at once?
The functions stack their effects—for example, running both fairxaero and nominimap will disable radar, caves, and the entire minimap. Use /function xaero:resetxaero to clear all restrictions and start fresh.
How do I turn off auto-run if I set it up?
Run /function xaero:autorun/set/disabled to stop any auto-run function from executing on player login.
Does this mod affect the server's performance?
No—this is a lightweight data pack that only modifies player-side map display settings without adding server load or entity processing.
Will resetting map settings affect players who are already logged in?
Running /function xaero:resetxaero clears the restriction flags, but players may need to relog or refresh their map display to see the changes take effect.
Can I restrict maps only for certain players or teams?
This data pack applies restrictions server-wide to all players—it doesn't have built-in per-player or per-team targeting, so all connected players receive the same map settings.
