Hi guys, I am currently implementing a â€œLie detectorâ€ (a.k.a polygraph) mini-game in my upcoming game PlayDetective. I have never been submitted to a polygraph test , so the gameplay is based on what I see in movies and read on the net. It works this way: you have a game character that you interrogate, the questions are picked by the computer, and can only be answered by YES or NO. Your goal is to detect when the character lies or says the truth. The interrogation procedure work as follow: 1 â€“ The first question is a â€˜truthâ€™ control question (the character will always tell the truth). You must observe the charts and see how they behave. 2 â€“ The second question is a â€˜lieâ€™ control question (the character will lie). You must observe the charts to see how they behave when the character is lying. 3 â€“ The actual test starts, the computer ask several questions, the character replies to each of them and for every question, you just have to guess if it is true or false (the time is limited). At the end of the test your earn money based on you success rate. http://www.kayokomputers.com/e-nkap/games/heartbreakers/beta/polygraph4.jpg http://www.kayokomputers.com/e-nkap/games/heartbreakers/beta/polygraph5.jpg Here is a YouTube video: http://www.youtube.com/watch?v=f1Srj-h8lLw You can also download the full-size video here: http://www.kayokomputers.com/e-nkap/games/heartbreakers/beta/polygraph.avi What I need to know is, how does is sound to you? - Difficult? - Fun? - Not fun? - Sucks (like the whole game)? By the way, the UI you see on www.playdetective.com is pretty old, the game has a new UI totally redesigned from scratch.
