Hello again ! I'm sorry if I'm hogging the forums, but this is a beloved project of mine and I'm something of a beginner in RPG Maker. As you can see in the file attached, I've got a parallel process common event that's supposed to mimic the effects of withdrawal. I know I've done the switches and the conditions properly, because the "You begin to feel pain more acutely..." message pops up as expected. What happens is that it pops up, and then... nothing. Whereas the other effects work all right, this particular one doesn't. It's supposed to lower the defense parameter when the second threshold has been passed, but for some reason it doesn't, either because it doesn't store the actor parameter variables, or because I did something wrong with my variables. Now I've downloaded Lunarea's Game Interpreter fix (which, btw, I don't know what it does exactly), I've tried messing around to see if only DEF was affected, What you see is only the very last attempt to affect that damned DEF. I've tried subtracting the variable from itself, dividing it by itself, dividing it by ten, and subtracting ten from it. Nothing works. tl;dr Basically, the value stored in the variable, which is the actor's defense, doesn't change at all, despite my best efforts. What am I doing wrong ? Any input is, as usual, appreciated. EDIT : The second screenshot is the end of the event, if that helps at all. It's supposed to stop the parallel process from endlessly repeating.
