Creating a Sound File
Using a Sound File in the Visual Programmer
In your project, you may want the sound file to play while other things are happening in your scene. To do this, select a wait of 0 seconds for the sound expression. This will cause the sound file to begin playing. Then the program will move immediately to the next expression while the sound file continues to play.
