So I'm going down the rabbit hole, my game is modded to a ridiculous extent, and I honestly want to start modding myself (maybe even fixing some dead mods I've had to relinquish to my 'waiting for update' folder). At this point, a lot of my questions are, where to start? I'm less interested in straight-up CC and moreso interested in learning how to create gameplay mods, tuning mods, overrides, add-ons and even some more complicated gameplay mods that may involve some level of CC (objects that can be interacted with) and animation. My understanding of script is somewhat dated (last time I really did any kind of major programming was...2009 I think?), limited mostly to web design. But I pick up on languages fairly quickly so I'm more than happy to jump into a new programming language and run with it, since I know a lot of what I'm wanting to do will involve learning Python, I've already found a few useful sites for familiarizing myself with the script, but getting familiar with s4pe is something else I really want to work on.
When it comes to modding specifically for the Sims, Google search is a bit overwhelming and some of the results, less than helpful for me. I'm very much a learn-by-doing person. I don't get much benefit from videos, audio, or the like, but rather prefer written instructions, like a how-to where I can easily approach each step at my own pace. I've found the sims wiki tutorials and I can see I've got my reading cut out for me, but where should I start? Is it okay to just jump into General Modding and go back to CAS, Patterns/Walls/Floors, Objects and Building if needed or should I go through it all? And what all do I need so I can make sure I've got it to practice with from the get-go (S4PE aside)? Are there any other more straightforward, better organized resources available for learning to mod? And before I get my hopes up and run into this like a cat on catnip, as someone who currently has little/no income going on disability, am I completely screwed if I can't pay for programs and don't have every EP/GP/SP going into this? I'm slightly overwhelmed, but excited to have found something I might really be able to get into during my good days that can help others since I've been unable to work, but I don't want to jump into it and get excited only to find that I have to pay to make a certain type of mod or people who have packs I don't own can't use or experience glitches I can't fix with a mod I make.
So, advice? Experience? Reassurance? Any help and even stories about how you got into modding, what your experience has been, would be greatly appreciated. Maybe even some input from others in a similar situation, just getting started or modding-curious individuals who can relate?
