Usage

my_btn._y:Number

Description

Property; the y coordinate of the button relative to the local coordinates of the parent movie clip.

If a button is in the main Timeline, its coordinate system refers to the upper left corner of the

Stage as (0, 0). If the button is inside another movie clip that has transformations, the button is in

the local coordinate system of the enclosing movie clip. Thus, for a movie clip rotated 90

counterclockwise, the enclosed button inherits a coordinate system that is rotated 90

counterclockwise. The button’s coordinates refer to the registration point position.

Example

The following example sets the coordinates of my_btn to 0 on the Stage. Create a button called

my_btn and enter the following ActionScript in Frame 1 of the Timeline:

my_btn._x = 0;

my_btn._y = 0;
