Moding (is it hard or not?)
 

Is it hard to make a mod meaning do I actually have to program raw code to make anything that I want the game to be or can I just simply change some config files(for example) I know I'm a noob but I don't want to be anymore. Thanks for looking, please respond! I am learning how to program in C and I would like to know if I could start changing things in my most favorite game :)

it depends on what you want to do, if you want to make something really amazing, like a jetpack, or flamthrower, it would require coding and probably a lot of it too. if you just want to make something simple, you could change some files.

If you don't use code, it's not a true modification.

Well "changing existing code" works too buddy ;)
