MCS Arthropods
by MCSilver64
MCS Arthropods changes how spiders, cave spiders, silverfish, endermites and bees behave and spawn, and it is delivered as a datapack.
What it does
The mod adds new arthropod types and changes existing spider behavior: spiders can hang from ceilings, and a spider has a 10% chance of appearing as a special variant, while a cave spider has a 5% chance. Silverfish, endermites and an aggressive bee type are included, and the bee attacks other mobs and ignores entities wearing one piece of chainmail. Arthropods are immune to fall damage but take drowning damage in water.
Natural spawning rules set the spawn chance for silverfish at 10% in strongholds, cave spiders spawn between y -32 and 32 with a 10% chance in mineshafts, and spider replacements happen at a 5% chance. The mod runs on Fabric, Forge, NeoForge and Quilt, and the datapack also installs on PaperMC and PurpurMC servers. Commands let a player start the menu or uninstall the content with a function.
The server must run the datapack, while players may skip it: only the server needs it. The mod is licensed under the Creative Commons Attribution 4.0 license and is not open source. Files exist for 1.19.4 – 26.3, with 26.3v1-mod for 26.3 as the latest build.
