Mob Crawl

Mob Crawl 1.7.0

Added

• In-game commands: no more restarting the game to change settings.
  • /mobcrawl status — inspect the nearest mob: is it eligible, is it crawling, its pose, hitbox height, current path.
  • /mobcrawl enabled <true|false> and /mobcrawl whitelistOnly <true|false>.
  • /mobcrawl whitelist|blacklist|tiltBlacklist list|add|remove <entity> — with tab completion over every registered entity, wildcard masks such as somemod:*, and a warning if the ID is not registered.
• Crawling arm animation. Mobs now reach forward along the ground instead of keeping their walking arms.
• Head correction for mobs whose head is rigidly attached to the body (creeper, witch, evoker, illusioner, pillager, vindicator, drowned) — they look ahead while crawling instead of into the floor.
• tiltBlacklist option for mobs from other mods whose own animations conflict with the body tilt.

Changed

• whitelistOnly now defaults to true. Out of the box only the listed vanilla mobs can crawl, so the mod cannot break mobs from other mods in large modpacks. Add your own with /mobcrawl whitelist add.
• Default whitelist is vanilla-only and now covers 16 mobs: zombie, husk, drowned, zombie villager, skeleton, stray, wither skeleton, creeper, witch, pillager, vindicator, evoker, illusioner, zombified piglin, piglin, piglin brute.
• Config comments are in English.
• Whitelist and blacklist matching is cached per entity type, so the per-tick cost is negligible even with long lists.

Fixed

• Mobs from other mods no longer walk around inside 1-block gaps at full height. The hitbox shrink used a different filter than the crawling logic, which let ineligible mobs keep a shrunken hitbox without ever crawling (most visible with Born in Chaos).
• Mobs no longer get lost or ram into walls after starting a crawl: movement is now driven by the actual navigation path instead of a straight line towards the target.
• Zombie, drowned and zombie villager no longer push their arms through the floor.
• Drowned no longer stares at the ground while crawling.
• Witch and evoker arm poses are correct at last.
• No more lying down and standing up several times per second after emerging next to the player.
• Config file is written in UTF-8; comments are no longer mangled.

Notes

• Vanilla-only by default. Modded mobs of roughly humanoid shape (about 2 blocks tall, walking navigation) work well — add them with /mobcrawl whitelist add <id>.
• Not compatible in a meaningful way with mobs from GeckoLib-based mods whose animations override the body pose; put those in tiltBlacklist.
• Client-side commands (/mobcrawl pose) are tuning tools and are not saved to the config.
