Alright, so I want to make a tool for representing a dungeon for D&D. I'm not that experienced with coding in DM, so how would I allow only certain players that I can choose see a trap, a secret door, a hidden monster, or maybe a small item that they need to spot. I want the objects to be able to be seen by the admin in one aspect, players that fail the check in another, and players that succeed in the last aspect. Could someone point me to something that would be useful in this regard?
