Usage

my_mc._x:Number

Description

Property; an integer that sets the x coordinate of a movie clip relative to the local coordinates of

the parent movie clip. If a movie clip is in the main Timeline, then its coordinate system refers to

the upper left corner of the Stage as (0, 0). If the move clip is inside another movie clip that has

transformations, the movie clip is in the local coordinate system of the enclosing movie clip.

Thus, for a movie clip rotated 90

counterclockwise, the movie clip’s children inherit a coordinate

system that is rotated 90

counterclockwise. The movie clip’s coordinates refer to the registration

point position.

Example

The following example attaches a movie clip with the linkage identifier cursor_id to a SWF file.

The movie clip is called

cursor_mc, and it is used to replace the default mouse pointer. The

following ActionScript sets the current coordinates of the movie clip instance to the position of

the mouse pointer.

this.attachMovie("cursor_id", "cursor_mc", this.getNextHighestDepth(),

{_x:_xmouse, _y:_ymouse});

Mouse.hide();

var mouseListener:Object = new Object();

mouseListener.onMouseMove = function() {

cursor_mc._x = _xmouse;

cursor_mc._y = _ymouse;

updateAfterEvent();

};

Mouse.addListener(mouseListener);
