About this Mod


Fear of Sound

Fear of Sound is a Forge mod that brings your world to life by making mobs dynamically react to nearby noises. Instead of just running away, creatures now have distinct personalities: some will flee in terror, while others will play dead and freeze in place! This adds a new layer of immersion and stealth gameplay, as your actions can startle creatures and influence their behavior in unique ways.

This is the opposite of Attract To Sound Mod.

Features

  • Dynamic Fear System
    Mobs listen for sounds like footsteps, block breaks, and explosions. They calculate a “fear radius” based on the noise intensity and decide how to react.

  • Two Unique Reactions: Flee or Freeze!
    Not all mobs just run! Configure which creatures flee from danger and which ones play dead, like a fainting goat.

  • Powerful Bypass System
    Want to keep your pets or special mobs safe? Bypass any mob using a Custom Name or specific NBT data. A mob named "Pet" or one that is {Silent:1b} can be configured to ignore all sounds!

  • Highly Configurable
    Nearly every aspect is adjustable via the .toml config file. Tweak sound properties, block muffling values, player step sounds, and entity lists to tailor the experience to your exact liking.

  • Built-in Mod Support
    Out-of-the-box integration for Simple Voice Chat and Tacz is included, with easy ways to add sounds from any other mod.

Installation

  1. Ensure you have Minecraft Forge for 1.20.1 installed.
  2. Download the latest Fear of Sound mod .jar file.
  3. Place the .jar file into your mods/ directory.
  4. Launch Minecraft with the Forge profile.

Configuration

Once installed, a detailed configuration file will be generated at config/fear_of_sound-common.toml. You can also use the in-game Mod Options menu. You can configure:

  • Bypassed Mobs: Define which mobs to ignore based on their custom name or NBT tags.
  • Fleeing & Playing Dead: Assign mobs to either the affectedEntities (flee) list or the playDeadEntities list.
  • Sound Properties: Add custom sounds from other mods and define their scare range and weight.
  • Block Muffling: Change how much sound is blocked by wool, solid, and thin blocks.

Compatibility

  • Designed for Forge 1.20.1 (tested with 47.4.0).
  • Should work alongside most sound or AI mods, provided they do not add conflicting high-priority AI goals.
  • Requires no additional libraries beyond Forge and Minecraft.
