Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.

In vanilla Minecraft, slimes ignore light level when spawning inside a slime chunk.
This mod changes it. Now slimes won't spawn if there's light, making it possible to spawn-proof area from them.
These changes only applied to slime chunks. Slimes that spawn on surface in a swamp biome are unaffected
