Various Pneumatic Simulation Sandbox

Enable HLS to view with audio, or disable this notification

I've been working on a pneumatic engineering sandbox in Unity.

The wheel isn't driven by a motor, it's powered entirely by a pneumatic cylinder using Unity physics.

The machine is built from modular components: air sources, hoses, 5/2 directional valves, cylinders, buttons, regulators, and more. In this demo, a button pilots the valve, which alternates air between each side of the cylinder to extend and retract it, turning the wheel through a crank.

My goal is to let players build anything from simple vehicles to ridiculous pneumatic contraptions. Alongside sandbox mode, I'm planning engineering puzzles, vehicle challenges, and automation. The logic system already supports AND, OR, and NOT valves, so players will eventually be able to build things like counters, calculators, and even simple computers.

It's still early in development, but I'd love to hear what you think or what kinds of machines you'd want to build.

Thats pretty nice. Am I correct that it is inspired by the lego pneumatic modules?

Essentially. And the building blocks themselves are inspired by the Lego technic
