I downloaded Jet's animated battlers script and laid it out how he explained, but it just didn't work, like not even an error, just normal static images. I figured because it seems like common knowledge that everyone had yanfly or whatever installed that was probably the problem, but it seems like there's been recent controversy with yanfly putting a paywall on his scripts? I thought it was just a base, but people seemed to say it added annoying or unwanted features which I don't understand. I only want a first-person battle view with animated battlers while everything else is vanilla, but I don't know if I need a battle or core engine, or even if those are the same things. What engine would make Jet's script work, or do I even need one?
