If coordinating sound production with other events is complicating things
one thing that may help is the class QueueSound. I am not sure about what
version in which this class appeared. Basically, you throw sounds in it, and
they come out one at a time. With a one-liner change you can have it notify
you when its almost out of sounds, eliminating any need for polling and
making things quite efficient and easy.
