Yeah, this is a massive rewrite. Most, if not all, files the injector references were either moved or split up and then moved. I'll be honest, I don't know why RonChon did half of this stuff. Like, I'm all for OOP and file and class organizations, but, in CS 101 or 102, you learn that you can over organize. It feels like this is getting close to that. Like, technically, he re-implemented ability points (for those that don't know, ability points in this game use to be a variable. Like you have 10 left to spend. But a while ago, ability points was no longer a variable but a mathematical calculation of ((your level) * (some number)) - (the cost of all the abilities you've purchased)) but have them stored in a different variable. NGL, whenever I see this kind of flip-flopping on algorithmic design decisions (deciding against a design and then going back to it), it usually means the program itself is not in a good place and the very core principles of the program in question, was shaky to begin with. Ironically, this is pretty much what happened with python from it's inception to python 2 and then from python 2 to python 3 (which renpy is built on).
Now, this is just a feeling. I've not yet looked at all the refactoring and compared code versions. But these are usually the first alarm bells.
Though this does give me some feeling of vindication. Between the ability points being added back in as a variable (though, in a different place. Which, I would argue, is a worse place.), the reduction in grinding, and the increase in love/trust caps per season, it proves that all the people the kept shitting on me for saying things like "The grind takes too long" and "If you want story progression to be linked to your level, you limit the story progression to your exp, not the exp to the story progression." were absolutely wrong. Like, Loafy Lemon, one of the devs for the Witch Trainer Silver mod blocked me for one of these comments. It really does show that I did my math right and a lot, and I mean A LOT of people were just talking out of their ass.
I really feel sorry for anyone that's made a mod for this game up until this version. They're pretty much going to have to rework the whole thing.
