I have decided to use the yellow metal door models that are split, essentially having a lower and upper door that will move after the set up timer is finished. The upper door obviously moves up and the lower door will move down. I have a total of 6 doors (each consisting of a lower and upper door). This is a ctf map sorta set up like Hall Of Death. I need all the doors to open at same time and then remain open until end of round. Can somebody give me a good tutorial on how to do this. I need to know what entities I need for all of this, including a team round timer if that is what is needed to control the door models. Thanks much.
