Sounds like a bold topic, however, I am doing an event in my game where the villain sets off a bomb in a club. I have switches for the blocked paths and fire and switches for the survivors as well. What i need help with is making it so you have to rescue people before you get outside. I know I can put a switch at the door where it'll say "I have to see if more survivors are inside" But what I need help with is how to make that count down to where after I grab the 5 or 10 people that need saving then I can go outside and finish the event? And on the topic of that any way to make the atmosphere look a lot more realistic? thanks in advance.
