i was thinking of making a map that would have some puzzle elements in it and i was wondering how hard it would be to make it where i could play a small tune on the playable piano and have a door open (idea came from scooby doo) like you get trapped in a room with the piano and a pice of paper has a riddle on it where you have to "awnser" the riddle by playing f e e d on the piano to open a hidden door. i want to know what i would have to do to make that happen or if it's even possable?
