Creating Random Motion with Flash ActionScripts and Math.random

onClipEvent (enterFrame) {
this._x = this._x + Math.random() ;
}

To break this down simply, what this script does is tell Flash to check the x (horizontal) position in pixels of the symbol referenced by this, and then add the random number generated by Math.random to it so that it moves fractionally to the right.
