I'm taking a shot at this, stay tuned for Sophie's Safecracking Simulator. #jamulator https://itch.io/jam/jamulator-2021

I've been looking up safecracking videos and combination lock explanations for weeks.

I'm gonna go way too in-depth and even sim the texture of the wheel surfaces so you can get an audio spectogram of the fence running along them. It's a dumb project and I'm psyched for it.

dial/spindle and flys/pins working. I think the harder parts are going to be the IK for the nose/fence and bolt. also generating wheel meshes procedurally, because i forget how to do that *every time*.

Not entirely sure *why* I'm working on this project tbh, but it's better than working on nothing.

More accurate models/sim. Works well enough that if I know a combination I can get the gates to line up perfectly by looking at only the dial. Next step is working on the cam and lever/nose/fence - then I can sim the feedback that will let you crack it!

It's probably obvious but I decided I'd rather have nice looking lock components than procedurally generated models. I will just be moving/scaling parts and not doing any mesh-generating code.

I started modelling the cam/lever/bolt. I think their motions will be keyframed animation that I can play based on the state of the wheels & shaft. It's going to be a big headache to implement tho...

On the plus side, this is starting to look like the back of a combination lock!

Nose falls into the cam, but only part-way if wheel gates aren't aligned with the fence. Also, how far the lever drops is determined by individual wheel radii - it bumps along a little as it makes contact with the widest wheel :D

Next step is to make the cam pull the lever/bolt!

I'm happy to get to this point, because you can pretty much watch just that video and figure out how a real combination lock actually works :D
