Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

Mod loader NeoForge1 build
Mod loader Forge1 build

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

"while playing LEFT 4 DEAD 2 i noticed that the infected can crawl in game

i searched Modrinth and CurseForge for a mod that adds crawling AI to zombies but i couldn't find one :(

so... i made it myself! >:3"

this mod adds crawling AI to illagers and zombies! now they can crawl!!

the mod is highly configurable! (Config: crawlmod-common.toml) (AND! you can use this mod in any modpack)

"About versions"

"now for Forge 47.4.10! and 1.21.1 NeoForge! (holy moly)"

1.0.0: added new movement variant for zombies and illagers with simple AI (perfect for testing the mod)

1.1.0: i added list of mobs who can crawl! yay!!

1.1.1: testing a new crawl AI

1.1.2: Fixed mobs crawling too early (finaly) and mobs can now crawl throug windows one block above the ground (or something like this)
