Stormie's Spiders 🕷️

This mod is a fork of Nyf's Spiders and Spiders 2.0 leveraging Architectury Loom for multiloader support.


Enhances spider's pathfinding and allows them to crawl realistically up walls and even across ceilings! Compatible with most resource packs and mods.

Mod is required on both clients and servers for expected functionality.


Additions

  • Updated for newer versions
  • Readded spiders unable to climb during rain feature from Spiders 2.0 (experimental)
  • Added config screen (Mod Menu recommended to change clientside settings on Fabric)
  • Added option to disable crawling on ceilings
  • Added orientation fallback on servers without the mod (so spiders still rotate)
  • Added disabled blocks config/menu (for making traps, spider-proof bases, etc)
    • By default Spiders will not be able to climb over trapdoors. Any block can be added here
  • Spiders now avoid water while chasing target
  • If in water, spiders will attempt to swim back to shore
  • Reduced spider attack range (togglable)
  • Toggle to disable spider swimming (they will just sink in water)
  • (3.3.0+) Added a Rotation Overrides config menu that allows applying spider rotations to any mob desired (note, only adds rotations, no pathfinding changes)
  • (3.3.0+) Via Rotation Overrides menu, spider entities can now be disabled so that the mod doesn't effect them anymore (useful for disabling certain broken modded monsters that break when using this mod)

Fixes

  • TPS timeout crashes (if you have any TPS related issues, please let me know I would like to fix them if possible!)
  • Spiders randomly pausing while in chase
  • Stuck detection is now more robust (spiders can get unstuck easier)
  • Mildly improved performance while pathfinding
  • Spiders are now able to climb up/down stairs

Compatibility

  • Valkyrien Skies 2 compatibility
  • Sable/Aeronautics compatibility (not perfect, spiders cannot climb up walls reliably but still a huge improvement over vanilla) (1.21.1)

Incompatibilities

  • PotsandMimics (works but crashes have been reported during gameplay)

While with the fallback, spiders do rotate without needing the mod on the server, it is still highly recommended to have it on the server for the best experience.

Trapdoors are disabled by default in the disabled blocks config.
