A question you might not be able to answer but point me in the right direction..

I’ve just finished my second year in my computer science degree and honestly I was just thinking I’d like to try create some gameplay mods for my game (well attempt)

Though, I don’t aftually know where to start or what to look into (I mainly study web/mobile dev so programming isn’t so much my strong suit though I do know the basics and I’m willing to teach myself what I need)

I’m looking to create something similar to the explorer mod or social activities mod where I can add an option to the phone that allows my sims to go away and do whatever is chosen and while away to learn skills, moodlets, relationships etc.

I know this is a lot to ask but even some tips will help me out.
