Yikes, I would suggest here that you go with a script then. Not to dock you or anything, but if you're not sure how to make a switch, I would say that this kind of level event system is out of your league. Though to answer your question, when you make the common event and set it to a parallel process, the switch drop down menu will not be greyed out anymore any you can pick a spot. So pick any number and name it. What that means is that, if the switch number you chose is turned ON somewhere, then that common event is active constantly until that switch is turned OFF. So since it's a level event system, it would be best to have a common event per level as to save on the number of processes running. So for instance, in your first common event, if Variable:0001=Aluxes Level, is == 2 (which means, if Aluxes is level 2) then *Show your screen and stuff here*, and turn OFF the switch used to turn the current common event ON. (So basically, turn off the event you're running right now) and to finish it off, Turn ON a
different switch to start the next event which checks if your character is level 3 yet. 1 common event per level, each common event needs a different switch. You could probably get away with running a few of the common events at the same time by using the same switch for like 4 or 5 of the common events then turn that one off and a new one on for common events 6-10. I'm just trying to think of ways to reduce lag, because this system's real problem is the lag it's going to create checking a ton of things constantly. It gets more complicated with more players/characters you have. Also, to anyone else, I know there are more compact ways of doing this, but this seems the easiest for him.
Ok, are you trying to do this in battle or outside of battle?
This wouldn't do well in battle lol. You can't really get EXP inside of the battles the way they're set up now until afterwards, unless he edited the battles somehow so that after each use of something he gains a little EXP each time or if it's set up in an ABS of sorts. :p
