Disappearing events

I was wondering if there was a way to make events disappear after being triggered once?

and if there is, and the event is attached to an npc will the npc's sprite also disapear when the event does?

The easiest way to accomplish this is to use a self-switch at the end of the commands you want to happen. Create a second page and set its Condition to that self-switch. If you want it to disappear completely, do not put a graphic on the second page. If you want an NPC to still be there, put that graphic in. If you want the NPC to say/do something different, put that in the commands of the second page.

Thank you so much!
