In my latest AE, I tried to tell a story. There were Ally, Hostage, and Defendable Objects along a path through a medium warehouse, some Front, some Middle, and some Back. Upon entering the warehouse, every dialogue from every item was triggered and spoken at once. Even the big finale Ally in the Back that would be the end of the fight said his lines!
Please reduce the distance that triggers dialogue! I suggest Melee or Close Cone distance so you actually have to get close to a object or toon to trigger it.
Even if you could fix it so only the three Zones (front,middle,back) would trigger, that would be a big help!
