I have yanfly's save engine reporting various variables for tracking game stats, like battles fought and steps taken. Since those are kept track of by rpgmaker itself I havn't programmed in anything to update those variables. I'm curious at which points people go about fitting in setting those variables to the game data. I know it could easily be set as a parallel process event always running, but I hate having lag from events so I've considered updating them on transition points or when save access is granted. I'm wondering what clever ways other people have thought of.
