Flash movie coordinates are measured in Flash movie pixels, which are determined by the original
size of the movie when it was created in Flash. Point (0,0) of a Flash movie is always at its upper
left corner. (The cast member’s
originPoint property is not used to calculate movie coordinates;
it is used only for rotation and scaling.)
The
stageToFlash() function and the corresponding flashToStage() function are helpful for
determining which Flash movie coordinate is directly over a Director Stage coordinate. For both
Flash and Director, point (0,0) is the upper left corner of the Flash Stage or Director Stage. These
coordinates may not match on the Director Stage if a Flash sprite is stretched, scaled, or rotated.
Parameters
pointOnDirectorStage
Required. Specifies the point on the Director stage.
Example
The following handler checks to see if the mouse pointer (whose location is tracked in Director
Stage coordinates) is over a specific coordinate (130,10) in a Flash movie sprite in channel 5. If
the pointer is over that Flash movie coordinate, the script stops the Flash movie.
-- Lingo syntax
on checkFlashRollover
if sprite(5).stageToFlash(point(_mouse.mouseH,_mouse.mouseV)) =
point(130,10) then
sprite(5).stop()
end if
end
// JavaScript syntax
function checkFlashRollover() {
var stf = sprite(5).stageToFlash(point(_mouse.mouseH,_mouse.mouseV));
if (stf = point(130,10)) {
sprite(5).stop();
}
}

Usage
the stageTop
Description
Function; along with stageBottom, stageLeft, and stageRight, indicates where the Stage is
positioned on the desktop. It returns the top vertical coordinate of the Stage relative to the upper
left corner of the main screen’s desktop. If the Stage is in the upper left corner of the main screen,
this coordinate is 0.
When the movie plays back as an applet, the
stageTop property is always 0, which is the location
of the left side of the applet.
This function can be tested but not set.
Sprite coordinates are expressed relative to the upper left corner of the Stage.
