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.

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.

This mod adds curtains made out of Rope and Chain, allowing players and other large mobs to pass through, while smaller mobs are too weak to get trough them and get blocked.

The mobs are data driven, so you can add support for other mods and fully customize which mobs should be able to go through and which not. The tags are critter_barriers/tags/entity_type/rope_blocked_critters.json and critter_barriers/tags/entity_type/chain_blocked_critters.json

Using the default configuration, following mobs will be blocked from passing through:

Rope
- Bees
- Frogs
- Silverfish
- Bats
- Parrots
- Allays
- Endermites
- Chickens
- Vex (They can pass trough blocks, but if another mod changes that, they will also be blocked)
Chain
- Cat
- Fox
- Armadillo
- Rabbit
- Ocelot
- Wolf
- Axolotl
- All from the rope list
