I have a .xml file which loads the images into flash and I have a empty movie clip with a pivot. I want to make it centered but it makes it 0,0 (x,y) and some pictures have different widths. How do I make it so all images are centered?

I do not know of a function to do this, but I've just worked out the algorithm for you, of which I believe will work. Bearing in mind that you want the coordinates of the top left point of the image. You would have the following algorithm:

Code:

X - Y = Z / 2 = Axis Position

For instance, if the width of my document was 800 pixels and the height 400 pixels. The image I am loading in is 450 pixels by 200 pixels. The following algorithm would be used:

Code:

Width:	800 - 450 = 350 / 2 = 125 = X
Height:	400 - 200 = 200 / 2 = 100 = Y

That is:

Code:

Document Width - Image Width = 350 / 2 = 125 (Which is X)

Therefore you would set ._x and ._y to 125 and 100, respectively. I have also wrote you a function for this to be used in Actionscript:

Code:

function getCentreAxis(iWidth, iHeight)
{
	arXY = new Array();
	arXY.push((Stage.width - iWidth) / 2);
	arXY.push((Stage.width - iHeight) / 2);
	return arXY;
}
