When I was 13 years old, one of my friends at the time thought of an idea for a script mod for GTA IV. I thought the idea was cool and wanted to make it, so I started looking at examples of scripts, some other people's code, and read tutorials to learn how to make a script mod. The most popular language being used for script mods was C#, so that's the language I learned. After maybe a week of learning/coding, I was finished with my first mod: Check Engine Light. Basically it just displayed a red Check Engine icon on the screen when your vehicle's health is low. I sent the mod out to my friend (which sadly did not work for him, for unknown reasons), and I uploaded the mod to GTA4-Mods.com. This is how my programming “career” started.
I've made 35+ script mods for GTA IV (some deleted because they were badly made or useless) and 30+ for GTA V uploaded to GTA5-Mods.com. I've been making mods since 2013, but since around 2018 I've been slowing down as my interest in the game has lowered.
