Hey Guys,
I can't quite figure this out. I tried to do a search, but couldn't find what I wanted.
Problem: I'd like to award 1 point for each NPC the player talks to the first time.
So, I set an boolean instance variable for the NPC. When the player talks to the NPC it sets the boolean to True. (I called the boolean "SpokenTo")
The I have an event:
System| For each NPC
NPC| Is SpokenTo
-> Add 1 to Score

But the counter continually goes up after speaking with the NPC. I tried a "trigger once when true" condition, but it didn't work.
Sorry, I don't have a capx to share, but I can make one if necessary.
Edit: I should also note that each NPC has a unique instance variable (in my case, each NPC has a unique name).
