BioLock Scanner
by JNKY
BioLock Scanner is a NeoForge block that turns redstone on only when a player, and no mob or other entity, stands within its detection radius.
What it does
The scanner suits doors, traps, vaults and automated systems that should react to people. Builders place it as part of a redstone setup and can mount it on floors or walls, giving a clean, adjustable way to control access in both survival and creative builds. The mod runs on client and server, and it is meant for singleplayer and multiplayer use alike, so servers and players both need it. Files are published for NeoForge 1.21.1 only, with version 1.0.0 as the latest file, released on 2026-06-18 on the beta channel. BioLock Scanner is not open source and is released under All rights reserved.
Key features
Player-only detection
The scanner activates redstone only for players, so passing mobs do not trigger secure doors or traps.
Configurable radius
The detection radius can be adjusted, letting builders set how far the scanner reacts to a nearby player.
Floor and wall mounting
The block can be placed on floors or walls as part of a redstone circuit, fitting a range of base layouts.
