I'm making a map with a giant door that has to take a ton of damage before opening (about 10,000, to be exact). So far, I've gotten the door to work using a func_breakable, but I'd like there to be a health bar over the door to show how much health it has at all times. I was thinking of making a brush that scales itself in accordance with the health percentage, or something along those lines, but I don't know how to do this. Could somebody explain to me how I could make a healthbar? Also, I'd like to make it so that only one team can attack the door. It sounds simple enough, but I'm unsure of how to do this as well. Any help would be greatly appreciated!
