Chat Range

A server-side Fabric mod for Minecraft 1.21.11 that limits chat visibility to a configurable block radius. Players only see messages from others who are nearby — including chat, death messages, notifications, and advancement announcements.

Requirements

• Minecraft 1.21.11
• Fabric Loader 0.18.0+
• Fabric API 0.141.3+1.21.11

Installation

1. Install Fabric Loader for Minecraft 1.21.11.
2. Download Fabric API for 1.21.11 and place it in your mods/ folder.
3. Place chatrange-1.0.0.jar in your server's mods/ folder.
4. Start the server.

The mod is server-side only — clients do not need to install anything.

Commands

All commands require operator permissions (gamemaster level).

The radius is in blocks. Example: /chatrange set 100 limits chat to a 100-block radius.

What is filtered

When enabled, the following messages are limited to players within the configured radius of the source:

• Player chat — messages typed in chat
• Command messages — /say, /me, etc.
• Death messages — only nearby players see when someone dies
• Advancement announcements — only nearby players see advancement completions

Messages from the server console are always broadcast globally.

Configuration

Settings are saved automatically to config/chatrange.json on your server:

{
  "enabled": true,
  "range": 64.0
}

You can edit this file directly while the server is stopped, or use the in-game commands while it's running.

The default radius is 64 blocks. The mod starts disabled on first install — use /chatrange set <blocks> or /chatrange on to activate it.
