ChTR

A message that starts with the global chat prefix is delivered to all players on the server. An ordinary message is delivered only to players in the same dimension who stand within the local chat radius of the sender. Both values are set in the config, which defaults to a global prefix and a local radius of 100 blocks. The chat logic runs on the server side, so only the server needs the mod to route messages.

If no other player is within range, the sender receives a warning message. A separate option, warnIfNoListeners, controls whether that warning is shown at all. The mod supports formatted warning and chat messages, with placeholders for the player name, the message text, the current local chat radius, the current global chat prefix and the number of listeners. Formatting codes from 0 to 9, a to f, and l, o, n, m and k are supported in these messages.

Players connecting to a server that runs ChTR do not need to install anything, because the environment is server-side only. Files are published for NeoForge 1.21.1, with 1.0.0 as the latest version, released on 2026-04-23 under the MIT License. The mod is not open source.
