ObsidiPlates Mod 1.7.10 provides Pressure Plates that can only be activated by either Players or NPCs, depending on what they’re made of.
How it works:
All plates are a type of switch that can be placed onto the surface of a block. If connected, by wire, to an object (or placed adjacent to a block that can be powered), it will provide power to that object or block when stepped on by a player (or NPC, if a Mossy Pressure Plate) and will stop when stepped off.
As opposed to wooden and stone pressure plates, Obsidian Pressure Plates will not respond to items or NPCs and Mossy Cobblestone Plates will not respond to items or players.
