About this Mod
A server-side fabric mod that reconfigures bat spawns
This mod prevents new spawns instead of killing spawns that go beyond the custom limits.
If installed on a server, individual players do not need to install it as well for this mod to work.
Features
- Limit bat spawns up to a certain number.
- Limit bat spawns up to a certain max y level.
- Use command: /bats to check how many bats are around you in a non-immediate despawnable area (128x128x128). Accessible to everyone.
- If you have access to server logs, you can check that the mod outputs the position for each detected bat.
How to use
- Drop this mod into your minecraft mods folder.
- After starting up the game once, locate the batsreconfig-common.cfg in your minecraft config folder.
- In there, you are able to change each feature value. Default values are already set.
- Restart the game to see new changes.
