The name or identifier of an object created with the Object class, specifying the x and y

coordinates as properties.

Returns

Nothing.

Description

Method; converts the point object from the movie clip’s (local) coordinates to the Stage

(global) coordinates.

You can extend the methods and event handlers of the MovieClip class by creating a subclass.

Example

The following example converts x and y coordinates of the my_mc object, from the movie clip’s

(local) coordinates to the Stage (global) coordinates. The center point of the movie clip is

reflected after you click and drag the instance.

this.createTextField("point_txt", this.getNextHighestDepth(), 0, 0, 100, 22);

var mouseListener:Object = new Object();

mouseListener.onMouseMove = function() {

var point:Object = {x:my_mc._width/2, y:my_mc._height/2};

my_mc.localToGlobal(point);

point_txt.text = "x:"+point.x+", y:"+point.y;

};

Mouse.addListener(mouseListener);

my_mc.onPress = function() {

this.startDrag();

};

my_mc.onRelease = function() {

this.stopDrag();

};

}
