Transcription: I needed some way for the firing button to know where each of the wagons are in its rolling along the horizon line as to whether or not you fired the cannon at the right time or not. And using this cannon animation as a QuickTime movie, it allowed me to be able to calculate the movie's movie time, or how much time has elapsed since the beginning of the playing of the QuickTime movie. It's a very simple script, I'll show you that.
