A little interactive record player that plays music only when the turntable is spinning and the tone-arm is over the vinyl. The play count updates every time you start listening to the music.
I made buttons that broadcasted states (e.g. StartSpin/StopSpin) which in turn triggered motions (e.g. the record starts spinning/stops spinning). I then made it so music only plays when several conditions are satisfied. The play count variable updates when music is played, no matter in what order the sprites are toggled. I had to make some work-arounds due to things like no 'Sensing' options for detecting motion. All the work (apart from the vinyl and tone-arm pictures) is my own - Jay Parmar 2014.
