SHEAR LINE

A lockpicking simulator that doesn't roll dice.

Play it now at lockpick.fun

Every lock here is a real mechanism, simulated. Picking has no hidden success chance and no progress bar: a pin sets because you lifted it to the shear line while the plug was pinching it, and a spool that drops the plug into a false set is a waist and a rim doing what they do.

What is in here

src/	The game. A Godot 4.7 project (GDScript, 2D): the pin lock is engine physics bodies, and binding, setting, false sets and oversets are what those bodies do. Exports for the browser, Windows and Linux.
old/	The original browser version (TypeScript and a canvas), with its own contact solver, its tests and its tools. No longer developed; still playable at lockpick.fun/classic.
.github/workflows/deploy.yml	Tests both, exports the game for the web and publishes the site on every push to main.

Running the game

With Godot 4.7.2 (G is its executable):

G --headless --path src --import    # once after a checkout
G --path src                        # play
G --path src --editor               # open in the editor

Controls, how the lock works, the builds and the tests are in src/README.md.
