I am in the process of building a proof of concept mod which would allow blind and visually impaired people the ability to navigate inside of GTA V. I'd be happy to expound on this in another topic, but yes blind people play games, and I want to see if I can prove that navigation is possible.
The issue I am running in to is figuring out what coordinate system GTA V uses. I know that you can get a player's curren theading, but I'm unsure how coordinates are actually layed out. I unfortunately stopped my math studies in highschool at geometry, so I'm unsure of the different types of coordinate notation.
I know we get a vector which contains x y and z, but I'm unsure what each of these measure. I'm also wondering how coordinates convert to real world distance. is each incramented value a meter? Any help is appreciated.
