Centered placing of a mc onto another via action script

Question

Hello,
i have problems to place a mc object (any rectangle) centered
onto another mc object (any rectangle) via as-code. Via the polar()
method it is possible to translate points with a certain distance
and angle. I tried with that method to place the first rectangle
centered onto the second rectangle. It works fine for an angle of 0
degrees for the second rectangle. But if you change the angle of
the second rectangle the determination is no more correct.
Can someone someone help me?
You just have to create 2 rectangles as movieclips in a flash
document and name them as "draggedObject" and "dropObjects". Then
attach the following as-code and try out:
draggedObject.x = dropObjects.x; // draggedObject is the red
rectangle, dropObjects the blue rectangle
draggedObject.y = dropObjects.y;
var angle1 = dropObjects.rotation;
angle1 = 2 * Math.PI * (angle1 / 360);// angle to Bogenmass
draggedObject.rotation = dropObjects.rotation;
var newPoint = Point.polar(dropObjects.width/2 -
draggedObject.width/2, angle1);
draggedObject.x = draggedObject.x + newPoint.x;
draggedObject.y = draggedObject.y + newPoint.y;

Answer 1

well, there are several ways to align objects on the stage.
1) construct the objects so that thier registration points
are in the center of the object, then either can be aligned to the
center 0,0 of the other, and rotated about that point.
2) if the objects registration point is in the upper left
corner, use the Stage's width and height properties to align the
obects to the center, by setting the _x position of the object by
subtracting the width of the object from the width of the Stage and
dividing the result by two. do this again each time you rotate an
object, as the bounding box is changed to accomidate the entire
bounds of the shape, after rotation occurs.
AS2: draggedObject._x += (Stage.width - draggedObject._width)
/ 2;
AS3: draggedObject.x += (stageWidth - draggedObject.width) /
2;
(I am uncertain if this is the correct method of calling of
the AS3 'stageWidth' property here, as I'm new to AS3)
3) there are more ways to accomplish this, but this should be
enough for now.
