Bats Reconfig

by gittyaulia

Bats Reconfig lets a server owner change how many bats spawn and the height above which they stop spawning, through a Fabric server-side config file.

What it does

The mod reconfigures bat spawns on a Fabric server. Operators can cap the number of bats that appear and set a maximum Y level, so bats spawn only below a chosen height. Before spawning, the mod counts the bats already present in a non-immediate despawnable area of 128 x 128 x 128 blocks, which keeps the population within the configured limit.

Settings live in the batsreconfig-common.cfg file in the Minecraft config folder. The file is created after the game starts once with the mod installed, it ships with default values already set, and a restart applies any change. A command lets operators use the mod in play, and the server log records the position of each detected bat, which helps when checking how the limits behave.

Config API and Fabric API are required dependencies. Only the server needs the mod to be installed; individual players do not have to install it for the mod to work. Players join without it, since only the server has to run the mod. Files exist for 1.21.4 and 1.21.5, with 1.1.0+1.21.5 for 1.21.5 as the latest file, published 2025-04-13.

Key features

  1. Bat count limit

    Caps the number of bats that can spawn, so a world with many nights keeps a fixed population.

  2. Maximum Y level

    Restricts bat spawns to a set height, keeping them below a chosen Y level.

  3. Area check

    Counts bats in a 128 x 128 x 128 area that can despawn, and holds spawns to the limit.

  4. Server logging

    Writes the position of each detected bat to the server log, so the output can be checked.

Where are the bat settings changed?

Values are stored in batsreconfig-common.cfg in the Minecraft config folder. Restarting the game after editing the file applies the new values.
