Cave (Johnson) Sounds

by MafiaToasterMan

Cave (Johnson) Sounds swaps the ambient cave noises in Minecraft for quotes from Cave Johnson, the character from the Portal series.

What it does

The mod targets the ambient cave sounds that play underground and replaces them with randomly chosen lines voiced by the character, with a configurable chance for a voiceline to play. Some lines depend on where the player stands, so location can change what is heard. Echo-based distance effects give the lines a sense of space inside caves and tunnels.

The voice lines are drawn from the game series and a few extra lines come from add-on content, and the author credits Hail JK Simmons as the voice. The project is still in development, so the set of lines and features may change. Installation needs Fabric API. Only the player needs the mod to hear the replaced sounds, and a server may run without it. The file is published for Fabric only, for 26.1.2, under All rights reserved, so the code is not open source.

Key features

  1. Random cave quotes

    Ambient cave noises are replaced with quotes chosen at random from the character's lines.

  2. Adjustable voiceline chance

    The chance that a voiceline plays instead of the usual ambient sound can be changed in the settings.

  3. Location-based lines

    Some lines are tied to specific places, so the quote heard depends on where the player is.

  4. Echo distance effects

    Sounds carry distance-based echo, which makes the lines seem to come from across a cave.

What the author says

This is a simple sound replacement mod that changes all of the ambient cave noises to quotes from Cave Johnson, primarily from Portal 2. There are a few lines from the Perpetual Testing Initiative, and a select few from other DLCs. This mod is still in development, so here are some things I would like to add: - Echo…
