Lua is used in script components. It can read and write composite data, so it can do the same stuff other logic components can do, but in a programatic way.
It can also draw stuff on a monitor or over a camera feed.
If you need more assistance or have more questions, you can always join the Official Stormworks Discord and ask your questions in the #lua channel.
