Comms Array Uplink
Comms Array Uplink limits which players can chat with each other on a Fabric server, based on distance and prior contact.
What it does
Players who come within 16 blocks of each other by default can discover one another and then exchange chat messages. Contacts see each other's chat. Players who have not met cannot reach one another through chat, and the discovery range is set by the server owner. The mod is server-side only, so players join without installing anything, and it runs on Fabric for 1.21.8 with the latest file 1.21.8-1.0.2, released under the GNU Lesser General Public License v3.0 only and open source.
Key features
Proximity discovery
Two players who come close enough to each other, within 16 blocks by default, discover one another as contacts.
Contact-only chat
Chat messages reach only the players who have discovered each other, so strangers stay out of the conversation.
Configurable range
The discovery distance is a server setting, and the range is measured with a box sphere around the player.
