Why getBounds() does not align with stage's scaling

[shabeerahmedshah]

Why is that the getBounds() of item doesn't return true bounds of that item in case of parent stage having a modified scaling?

What do you mean?

In other engines transform = projection * worldTransform . and both projection and world bounds are calculated. Pixi doesnt have that yet,

What I basically need is to draw a graphics rectangle on sprite to make it feel like selected. So I called sprite.getBounds() and use those values to draw the graphics rectangle.

It works fine when the parent container has 1:1 scale. but the rectangle moves forward from the sprite when scaling increased and vice versa.

BTW if we can  transform = projection * worldTransform, can we get the local transform of an object? though I could'nt find localTransform or transform property on a sprite.

I dont know why do you think it must have telepatic interface that determines which coords you actually need.

You need bounds inside the parent container, not global bounds.

pixiv3: getBounds(parent.worldTransform)

pixiv4: getBounds(parent.transform.worldTransform)

or just divide by that scale

Yes, I am using scale divide strategy for now. Thanks for help bro.
