Using the Pressure Plates in this mod you can apply icons. This will allow specific entities to trigger them. Here the cow is triggering the pressure plate but the pig can't.
Everything in the mod.
This shows the 4 different icon selections on the Entity Barriers. There are Cows, Villagers, Hostile Mobs, and the Burger Boss (from Burgers R Cool) all being contained.
In this screen you can select 4 Entities to block. These can be groups or mobs. The sword is the Hostile group. Modded mobs also automatically appear in the Detector and config (icon textures may not be included). Don't forget to click Apply to Detector.
This is what a basic area for entity barriers could look like. With no icons all entities can pass through.
All the blocks and items in this mod can be used in the Stonecutter. This is how you get the other textures of the Pressure Plates, Barriers, and Detectors. They all function the same. The other textures are from my other two barrier mods.
