Anand Hi! You are right, I could potentially generate a wall already with 2 points. As of now the walls as generated around the room shape for different reasons, so that's why I need a room first with 3 points minimum.
If you wish to generate a wall anyway, I can indicate where to look and add code. In FloorController::BuildRoom()
and RoomController::Rebuild() you will see a if statement with a "< 3" condition, you can add code before that for when there is only 2 points, to generate just a wall without the floor and ceiling.
