SHEAR LINE

A lockpicking simulator. Play it in the browser at lockpick.fun.

In most games lockpicking is a minigame with a dice roll behind it. Here the lock itself is simulated: pins, springs, a plug and a tension wrench. A pin sets when you lift it to the shear line while the plug is binding it. A spool gives you a false set. Push a pin too far and it oversets. There is no success chance anywhere.

What's in it

• 27 locks: 21 pin tumblers (the harder ones have spools, serrated pins, mushrooms and T-pins), 3 combination locks and 3 disc detainers
• a tutorial of 10 short lessons
• Lock Blitz: 5 minutes, open as many locks as you can
• a snap gun that works on 6 of the plain locks
• a lock editor, with codes for sharing a lock you built
• trophies, two themes, and a help section with pictures

There are two levels. Training colours the pins and shows which one is binding. Normal shows the same lock without the hints. Each lock gives you a rank for your time.

Controls

On the keyboard:

key
Q (hold)	tension wrench
← →	move the pick
Space (hold)	lift the pin, or turn the disc
1 to 0	wrench pressure
C (hold)	ease the plug back
R	restart
Esc	pause

Hold the wrench first. Without tension nothing binds and nothing sets.

Mouse, controller and touch work too, see src/README.md.

Feedback

There is a Feedback button in the game. You can also open an issue or come to the Discord.

The repository

• src/ is the game, a Godot 4.7 project. Details are in src/README.md.
• old/ is the first version, written in TypeScript. It is not developed anymore but still runs at lockpick.fun/classic. See old/README.md.
• .github/workflows/deploy.yml runs the tests and publishes the site on every push to main.

To run from source you need Godot 4.7.2:

godot --headless --path src --import    # once, after cloning
godot --path src
