By looking at events creating new events you can actually develop a lot more user interface program.
I imported some music and made my characters sing.
I simply used the create event.
Such when "key" is press play sound.
Good Job- Now try this.
1) Load a separate song for each character.
2) Create a "When mouse is clicked on anything event" that passes the object to a world method that sings that characters song.
If you set it up right, the method should be about three lines long
