About this project
What does Altas Security add?
Welcome to Atlas Security! Tired of other players easily wandering into your secret base? Atlas Security provides the ultimate protection for your redstone contraptions, hidden doors, and private vaults.
Main Features:
- The Security Terminal: A high-tech block that acts as a secure, password-protected redstone power source.

( You can put the Terminal next to a door )

- Custom Passwords: Set your own unique password through a custom, easy-to-use GUI.

*
( Enter the password, then other players can't destroy it )
- Strong Redstone Signal: When the correct password is entered, the terminal emits a strong redstone signal (power level 15) for a short duration. It acts exactly like a button, allowing the current to pass through solid walls to power your hidden mechanisms.
- Multiplayer & Mapmaker Ready: Perfect for protecting your valuables on multiplayer servers, faction bases, or for creating immersive puzzle and adventure maps.
How it works: Simply place the Security Terminal against a wall, set your secret password, and connect the block behind it to your redstone circuit (like an iron door or a sticky piston). Only players who type the exact password can trigger the mechanism and gain access!
