Data.json Skin Attachment props: scale[X|Y] and width|height

nicloay

Could someone explain me, where this properties used,
I understand that scale[X|Y] can be scale for the sprite, but why there are 2 more properties width and heigh.

Or for example you take sprite from atlas 25x25,
then in attachment you can set the size 100x100 and your sprite will be expanded,
And after that you set properties scale[X|Y]= (0.5,0.5) and this sprite will be shrinked to 50x50 ?

The width and height are the size of the image used in Spine. It is used in the editor when images can't be found and at runtime to determine the new size when using SkeletonJson scale. The region attachment's scale is a modifier for the width and height and is used because adjusting SRT in the user interface is expected. It's true we could just use width and height in the exported data and get about the same effect at runtime. One difference would be you lose your sense of "normal", or scale=1, when using only a size, though nothing at runtime currently makes use of this.
