576 Chapter 7: ActionScript for Flash

Parameters

targetCoordinateSpace

The target path of the Timeline whose coordinate system you want

to use as a reference point.

Returns

An object with the properties xMin, xMax, yMin, and yMax.

Description

Method; returns properties that are the minimum and maximum x and y coordinate values of the

instance specified by

my_mc for the targetCoordinateSpace parameter.

Note: Use MovieClip.localToGlobal() and MovieClip.globalToLocal() to convert the movie clip’s

local coordinates to Stage coordinates, or Stage coordinates to local coordinates, respectively.

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

Example

The following example creates a movie clip called square_mc. The code draws a square for that

movie clip and uses

MovieClip.getBounds() to write the coordinate values of the instance to

the log file.

this.createEmptyMovieClip("square_mc", 1);

square_mc._x = 10;

square_mc._y = 10;

square_mc.beginFill(0xFF0000);

square_mc.moveTo(0, 0);

square_mc.lineTo(100, 0);

square_mc.lineTo(100, 100);

square_mc.lineTo(0, 100);

square_mc.lineTo(0, 0);

square_mc.endFill();

var bounds_obj:Object = square_mc.getBounds(this);

for (var i in bounds_obj) {

trace(i+" --> "+bounds_obj[i]);

}

The following information writes to the log file:

yMax --> 110

yMin --> 10

xMax --> 110

xMin --> 10
