bgmusic.loadSound(“1.mp3”, true);

Returns the closest integer that is greater than or equal to the number returned by Math.random()*3.

Examples:
Math.random()*3 returns 0.254530019871891, Math.ceil rounds it to 1.
Math.random()*3 returns 1.808154902886599, Math.ceil rounds it to 2.
Math.random()*3 returns 2.119892139919164, Math.ceil rounds it to 3.

Got it? =)
