Lock & Block Security
by andersmmg
Lock & Block Security gives players creative tools for guarding a base: keycard readers, tesla coils, force fields, laser sensors and mines that can be triggered by redstone.
What it does
Keycard readers open doors and other protected blocks only when a keycard carrying the matching access secret is used. A secret code can be set on a reader so that it emits a redstone signal when the right code is entered, which lets a builder connect the lock to any contraption. Tesla coils zap anyone who comes near a protected area while they are powered by redstone, and force fields can be created to form unbreakable walls that players switch on and off.
The mod also covers explosive defenses. A player sensor detects a player near a trigger and sends a redstone signal, a laser sensor reacts when players or entities touch its beam, and a detonator can set off land mines, laser trip mines or proximity mines from a distance. Fabric API, Lavender and oωo (owo-lib) are required dependencies, and the mod runs on the client and the server, so both need it. It is published for Fabric only, for 1.20.1 and 1.21.1, and the code is released under the GNU General Public License v3.0 only, so it is open source.
