Entity Barrier
by Trunky
Entity Barrier adds barrier blocks that stop selected entities from passing through them, switched on and off by pressure plates and a detector item.
What it does
Barrier blocks are placed in the world and block movement for entities chosen by a configurable detector. Pressure plates can be set to allow access instead of blocking it, and any entity a plate is set to allow can trigger it. Pressure plates for villagers, Pokémon, Pale Oak and a few other cases are made by combining a stone pressure plate with a matching barrier block, and nearly every entity pressure plate is made from a plate and an Entity Barrier.
The mod requires Fabric API and runs on the client and the server, so both need it. Files are published for Fabric only, for 1.21.1, and the latest file is 1.0.0 for 1.21.1. The project is not open source and is released under All rights reserved.
Key features
Toggleable barrier blocks
Barrier blocks can be turned on and off by pressure plates, letting a builder open a path only for chosen entity groups.
Entity Barrier Detector
A detector item configures which entity groups a barrier stops, with up to four groups selectable per block.
Crafted barrier recipe
The Entity Barrier recipe yields 16 barriers from a gold ingot and iron nugget combination, and the detector is crafted from the same materials.
Modded entity support
Entities from other mods can be included in the detector, and a resource pack can supply icons for modded entities.
Config option
A configuration option lets server owners turn off the restriction for an entity type.
