How to mark something as "Secret"?

So, I am creating my first WAD, and I was wondering how you mark a door as "Secret".

What I mean is that, when the player were to open the door, it would say that "A Secret had been revealed..."

Can you tell me how? Thanks!

If you're mapping for GZDoom you can use the Secret Trigger actor, combine the Door open action with the Thing_Activate action via a script, this will reveal the secret once script is executed.

If you want something simpler you can use the secret sector special : https://zdoom.org/wiki/Secret

Thanks, everybody!

Or a much simpler solution is to just mark the sector the door opens to as Secret. No scripting required.
