Hey, I had an idea for my game where I'd like a character to appear and block off a doorway, but only the second time you walk into a room. The character can be "defeated" (thus unblocking off the door and allowing for you to leave) by giving them three objects that you can pick up. I was thinking of triggering the character with a hotspot, but I know that if I do that, the character will appear every time you try to leave the room when I only want it to appear once. Is there a way for me to create a one-time event like this? Thanks!
