Sorry for the late reply, I became inactive for a while.
Anyway, here is how it works:
The Parallel Process is checking the base level, job level, current AP and job of the character, but because it is a parallel process it continues to do it over and over again with any break in the loop. I can't do it by when the cursor moves as it still would be a parallel process so it would just lag after switching on that process. Yes, with it being triggered by a cursor movement means I can just switch off the process after it has done what needs to be done, but I wouldn't be able to do this as after it being switched off, the pictures would surely disappear along with the event (which would now be switched off).
That's basically the system in nutshell along with your idea using a manual trigger.
Thanks for the idea, but sadly it wouldn't work.
