⚠️WARNING: This level will CRASH unless you are on a nightly build of the game, commit 1620eca or newer.

So the Gearbox is an elusive unused object from a very early stage of the game's development. It has previously been unusable due to it crashing the game when being placed. However, I just managed to fix it up enough that it can be placed down and configured without crashing the game.

I haven't familiarised myself with gear axles and transmission yet and likely will not have time to do so in order to understand how well it works, so I am giving it out to the community to experiment with. Just a note of caution that it is still very buggy, expect it to probably not work, and the configuration dialog almost certainly does not work on Android. It will not be appearing in the sandbox menu anytime soon.

There is now also a Wiki page for the object, copied from the object help text. Good luck, have fun.

The input sockets can switch gears and I've managed to make a configuration where it can switch between two gears, but I don't know how to make them turn or how to use it for another contraption.

20 days ago ROllerozxa: Also somehow this level works fine in the browser version of Principia even though I haven't updated it to include the fix. I guess it's just built differently. The screenshotter will almost certainly crash if you upload a level containing it though so uh, don't do that yet.
20 days ago ROllerozxa: Also this is how the configuration dialog looks like, if someone is curious but can't play the level. It's really... abstract.
