DisplayObjectContainer size

[lukasyno]

Hey, What is any simple way to calculate width/height of displayObjectContainer? Width/height property is only for Sprite...

At this stage width and height are only available for sprites.

 

It would be good to add it to displayObjectContainer too.

 

The way it I imagine it would work is to loop through all children and get a max and min value to calculate width and height.

 

I will put it on my todos

Ok thx, so I will write some code..

 

DisplayObjectContainerUtil.computeWidth = function(target){    var w = 0;    const n = target.children.length;    for (var i = 0; i < n; ++i)    {        var child = target.getChildAt(i);        if (child.anchor)            w = Math.max(w, child.position.x + child.width * child.anchor.x * child.scale.x);        else            w = Math.max(w, child.position.x + child.width * child.scale.x);    }    return w;}DisplayObjectContainerUtil.computeHeight = function(target){    var h = 0;    const n = target.children.length;    for (var i = 0; i < n; ++i)    {        var child = target.getChildAt(i);        if (child.anchor)            h = Math.max(h, child.position.y + child.height * child.anchor.y * child.scale.y);        else            h = Math.max(h, child.position.y + child.height * child.scale.y);    }    return h;}

Exactly my thinking!
