I'm a brush work guy, triggers aren't my thing =( I had an idea spawning from this thread from MilkToast. http://tf2maps.net/showthread.php?t=498 IE a objective being pushed, Attack/defend. I'm sure with triggers, about anything is possible... I want to create attack/defend CP map. The map will be 90% push, and at the end you have to capture the point to win. Thing is the thing im not sure on is.. I want them to push the "stairs" to a canon, once the "stairs" are at the canon, the canon door will "open" to allow players to shoot up to the capture point on the rock wall. Trigger question is can i have a door on the canon that will only open when the "stairs" are next to it?
