Deconstructing a sample script

In the sample SWF file zapper.swf (which you can view in Using Flash Help), when a user drags

the bug to the electrical outlet, the bug falls and the outlet shakes. The main Timeline has only

one frame and contains three objects: the ladybug, the outlet, and a reset button. Each object is a

movie clip instance.

The following script is attached to Frame 1 of the main Timeline:

var initx:Number = bug_mc._x;

var inity:Number = bug_mc._y;

reset_btn.onRelease = function() {

zapped = false;

bug_mc._x = initx;

bug_mc._y = inity;

bug_mc._alpha = 100;

bug_mc._rotation = 0;

};

bug_mc.onPress = function() {

this.startDrag();

};

bug_mc.onRelease = function() {

this.stopDrag();

};

bug_mc.onEnterFrame = function() {

if (this.hitTest(this._parent.zapper_mc)) {

this.stopDrag();

zapped = true;

bug_mc._alpha = 75;

bug_mc._rotation = 20;

this._parent.zapper_mc.play();

}
