How do I make a key door in Ultimate Doom Builder?

[Retro Dino]

I got banned from the UDB discord so I can't ask in it, but I just need to know how to make a key door in UDB. Thanks!

You use one of the linedef specials which says "blue" or "red" or "yellow".

 

...What were you doing to get yourself banned?

Where is that? When I go to action and select the door I can just use door generic, there isn't a red or blue or yellow door.

Also, It started with an argument. I'm not good at technical stuff and I asked a question, they answered but I didn't understand the answer so they got mad, then I got mad. It was a whole thing but whatever. I also didn't read the error text and they got mad at that. (Whenever an error text pop's up I have a tendency to just ignore it, idk why). They where essentially mad that I didn't read the text and help myself, but even after reading it I still didn't understand what I was supposed to do. After that I was pissed so I started venting, then shitposting, then I got banned. I apologized to Boris, but I said you shouldn't get upset at people that are retarded like myself. If you go on my account you'll see I ask a lot of simple questions, but I'm pretty new to WADing and I'm just trying to learn. Like this question, I'm sure it's simple but IDK how to do it.

It sounds like you're building the map in Boom format or something, and I'm not familiar with that.

I figured it out, I'm just slow like I said. Thank you for the help anyways! :) I'm gonna make a video then post it here.
