Constant Spawning Slimes

Vanilla slime spawning in swamps depends on the time of day and the moon phase, and the new moon sets it to zero. This mod removes that restriction, so small, medium and giant slimes can appear on swamp ground around the clock at the usual vanilla frequency. Slimes still avoid spawning on bottom-half slabs, glass, leaves and carpets, because the mod uses the game's own spawn boundaries.

The mod runs on servers only, so players join without installing anything. Server owners can turn spawning on or off by typing a chat command such as slimes off, and the change takes effect at once without cheats or LAN. Fabric API is required, and the mod is built on its events so it should sit alongside other biome and creature overhaul mods. Game versions 1.21.4 – 1.21.11 have files, and the latest is 1.0.0 for 1.21.11, released under the MIT License. It is not open source.
