I've been trying to make a gravity gun for over 2 hours with zero success. The gravitator thingamabob or thingamajig only has one input, but the gun has 4 outputs (trigger, alternate fire, grab, drop). The joiner has all inputs only. The gun stock seems to come with its own fluxor source, but I welded more just in case. I have attached storage and laser emitter and wired them so they are active on the gun stock. However, the gravitator seems to never be flowing, no matter what I do (wire never lights up, unlike the others). I have no idea what I'm doing. I can shoot the barrel and a laser emits, but nothing happens. This is just like real life engineering. Rate ?/10. Maybe a tutorial that actually teaches you how to make something ... that would have been nice.

This game has potential but the thing is they don't tell you what each part does witch makes the game confusing because you don't know how to build.
