XaeroHeadTracker

XaeroHeadTracker lets you see the location of all other players on the server, regardless of distance, directly on the Xaeros's World Map.

You can configure whether to display heads and names.

You can also choose whether or not to share your location with other players.

If a player disables location sharing, the display of their last known location shows how long it has been since it was last updated. Players who share their location are marked as “Live”.

The mod is compatible with Xaero's Minimap so that player positions aren't displayed twice.

Even if the mod is installed on the server, it is optional on the client side if you do not wish to use it, but it is required to display the positions of other players.
