I Can't Hear

A Minecraft Forge mod that limits chat message propagation distance.

Overview

In vanilla Minecraft, chat messages reach every player on the server regardless of distance. ICantHear changes this — chat messages only propagate within a limited range, and players too far away won't see your messages. This brings a more realistic communication experience to multiplayer servers, encouraging players to move closer or use a megaphone to extend their reach.

Features

Distance Limits

Message Type	Base Range	Extended Range
Normal chat	48 blocks	—
`/say` (executed by player)	48 blocks	384 blocks
`/msg` / `/tell` / `w`	48 blocks	—
`/tellraw`	48 blocks	384 blocks

Base range: Without a megaphone, messages propagate only 48 blocks.
Extended range: Holding a megaphone and consuming energy extends the range to 384 blocks.
Console / Command block executions of /say and /tellraw are not distance-limited and broadcast globally.

The megaphone is the core item of this mod:

Energy capacity: 2500 FE (Forge Energy)
Effect: When held in the main hand while sending a message, consumes energy based on message byte count and extends propagation from 48 blocks to 384 blocks
Charging: Supports the Forge Energy standard interface; can be charged by other mods' charging devices
Durability bar: Displays remaining energy in the inventory via the durability bar

Crafting Recipe

Crafts an empty-energy megaphone. Charge it before first use.
