I'm not doing well at locating tutorials or guides on how to create the logic for spawnrooms and doors that are directly related to captured points on payload maps. I'd like to create forward spawns for Blu after they capture a point. I want them to start spawning in Red's starting spawn and move Red back to another spawnroom. As well, I'd like to create access doors that open upon a captured Blue point (example: the slow-opening door behind cp B on cp_steel. Thoughts? Directions toward a resource that might help me? Thanks, TF2 Maps Community!
