Graphics class's width and height?

I found Graphics class has width and height  properties.

 

I thought they would work since it's from DisplayObjectContainer but seems not working.

 

I guessed it's because the Display Objects in the container are not sprites but vector graphics?

tried setting different values into width and height.

 

Although I use scale instead of size but it would be lovely to have such feature or update the documentation.

 

Thanks guys

It's not working because the width and height properties-functions of DisplayObjectContainer has been commented for some reasons: http://www.goodboydigital.com/pixijs/docs/files/src_pixi_display_DisplayObjectContainer.js.html#l32

They where using the local bounds of the DOC to calculate and modify the scale value.

It's because a DisplayObject have no width and height. It's just like an infinite plane with some properties to help to interact with its children. If you add 4 sprites to a doc and modify the scale of the DOC, that will affect the scale of the 4 sprites. Or if you change the DOC position, that will also affect the 4 sprites position since every child position is relative to its parent.

The width and height properties of a sprite do not affect the DisplayObject, they affect the size of the texture linked to the DisplayObject.

Yes, the documentation needs an update. You could add an issue to https://github.com/GoodBoyDigital/pixi.js/issues
