scripting for GTA5
I'll start by saying that I am not a coder. I have no previous experience in coding anything prior to GTA5.
In saying that, though, I have managed to create my own fuel script based on individual vehicle fuel economy, I've scripted my own HUD, I've made a functional hotel / motel room rental script with a fully functional wardrobe, accompanying a fatigue system to make it necessary, and a bunch of other scripts to suit my style of gameplay.
The reason I'm saying all this is to encourage others to have a go at GTA5 scripting. It really isn't that hard to accomplish what you can imagine. You'll need the following to start:
Source code of other creators to study
Helpful people along the way (like @ikt who is generous enough with his knowledge to help noobs like me)
If you can't find it, make it. That's always been my approach to everything.
Hope fully this inspires at least one other person to give it a go.
I made a general overview of scripting a while ago, so that might also help:
