I'm trying to make a map for portal, mainly based on turret puzzles, but I can't understand how to make doors and how to make them work, I didn't really get any of the articles on the Valve Developer Community Wiki website. I've made a gap, but what do I do next? I want to make one of the normal portal doors. Thanks for the help!
By the way, don't bother telling me how bad I am at this because I know I am lol
