Question

with the formula below I can center one image horizontally.

 var xPoint= stage.stageWidth / 2 - imgWidth / 2;

In case if I may have more than one image, how can I center them horizontally?

Answer 1

You need to center them based on their total width. Assuming they all have the same width, something like that should work:

var imageX:int = (stage.stageWidth - images.length * imgWidth) / 2; // Assuming all the images have the same width

for (var i:int = 0; i < images.length; i++) {
    var image:* = images[i];
    image.x = imageX;
    imageX += imgWidth;
}

If they have different width, just calculate the total width by looping through the images.
