yo Not a TF2-related question, but a Hammer one in general. I'm making an Alien Swarm level with which I want to use a dynamic fire system; fire entities are scattered all around the map and I'd like to make it so that they ignite the ones they are immediately adjacent to on a timer. If left to grow, they will ignite each other in sequence and set fire to the whole map. If the player uses a fire extinguisher and puts one out however, they can cut it off. I've added a few fire entities that cannot be extinguished as they reignite themselves if the player extinguishes them. I can make it so that each fire ignites another one after a set amount of time but I'm having trouble with stopping the ignition if the first flame is extinguished. Imagine there are two points called A and B. If A is ignited, B will ignite after 10 seconds. How can I make it so that extinguishing A after is has been ignited will not ignite B? As I have it now, B will still ignite after the time limit even if A is extinguished. I hope this makes sense. If anyone knows how I can set this up I would be very grateful. I've been playing around with the logic entities for ages now and I still can't get a working system. Cheers.
