Flipping sprite and negative width

[julacariote]

Hello,

 

If I flip a sprite on the horizontal axis, meaning I set its scale to (-1, 1), the width of the sprite become negative because the width is defined like this in Sprite:

Object.defineProperty(PIXI.Sprite.prototype, 'width', {    get: function() {        return this.scale.x * this.texture.frame.width;});

This makes perfect sense if I scale my sprite to for example (0.5, 1), its resulting width would indeed be the half of the original size. But in the case of flipping a sprite, why not returns the absolute value to always get a positive width?

 

I guess this is done this way on purpose, I'm just wondering why a width should be negative?

Interesting catch. I also think width should return the absolute value.

 

EDIT: Now that I think about it, the negative width would probably make it more intuitive to calculate the visual bounding box of a sprite.
