A prop from Live Escape Grenoble using pygame.
A real word prop, we wired an antic mechanic piano to a Raspberry Pi; black keys play real music notes and white keys play slices of the infamous phrase of the Exorcist "Your mother suck cocks in hell".
Players must hit the 7 white keys in order to win the challenge that opens the piano top with a linear grip and plays the scary Exorcist music.
To reset the challenge (close the top), the game master plays a melody with 7 secret black keys.
This is a good example of GPIO events with debouncing and multi channel audio.
This prop was created before PyProps library was released so there is no dependencies with PyProps.
You will have to install following Python packages:
$ pip3 install paho-mqtt
$ pip3 install PyYAMLStart main.py script in /home/pi/Room/Props/PyProps/PygameProp/PygamePianoProp:
pi@raspberrypi:~ $ python3 ~/Room/Props/PyProps/PygameProp/PygamePianoProp/main.py -s 192.168.1.42 -d
pygame 1.9.4.post1

The command to relaunch the prop is :
$ ps aux | grep python | grep -v "grep python" | grep PygamePianoProp/main.py | awk '{print $2}' | xargs kill -9 && screen -d -m python3 /home/pi/Room/Props/PyProps/PygameProp/PygamePianoProp/main.py -s %BROKER%Piano Prop as a prop for xcape.io Room
This prop is used as a prop for xcape.io Room software.
Commands are in French; look at the code in PianoApp.onMessage() method.
