Vehicle Question

Alright, so, I play around with GMod and make my own little vehicles and gadgets, but I have a problem. I make a few, and I run out of keys on my numpad to control them all. So, I’m just trying to figure out: is there any specific way to code a vehicle to have active controls under certain circumstances (for example, I’m sitting in the chair, so the controls work, but when I’m not, they don’t)?


The Wiremod Pod Controller runs under this principle. It detects which keys you’vre pressed while in the pod then sends that output to whatever it’s wired to.
It’s possible to code a vehicle to do something like that, however it’s probably easier to make the vehicle contraption using wiremod than learning how to code lua and make entities.
Plus you’d have the advantage of being able to use your contraption on any server.
