Question

In actionscript 3 (as3) What is the difference between calling stage.width and stage.stageWidth

This was something I remember I got confused about in the past (Adobe\'s

Answer 1

stageWidth is basically width of the player window. You probably need this number if you want to know size of your scene. stage.width is calculated as any other width in actionscript. This means, it is width of bounding box around child objects of the stage. For example stage.width of empty.stage is 0. Or if you have only one small square 10 px wide on scene lets say 200px wide, stageWidth is 200, but stage.width is 10

Answer 2

I found this article http://ajarproductions.com/blog/2009/03/18/flash-stage-width-vs-stagewidth-in-actionscript-3/ which says:

"stage.width will return the width of the content on the stage and ignore any empty pixels around the edges. So if you only have a 100 px wide rectangle on stage, your stage.width will be 100.

stage.stageWidth will give you the size of the stage, more like Stage.width in Actionscript 2. Use stage.stageWidth if you’re trying to position elements relative to the stage.

Same goes for stage.height and stage.stageHeight."
