如何在 PixiJS 中通过全局坐标缩放图形 object？

Question

I have a PIXI.Container object that I need to scale straight up-and-down, by the Y axis of the camera. The object itself is rotated, so I don't want to scale by local co-ordinates.

This will scale the object by local co-ordinates:

container.scale.y = scaleFactor;

How do I scale it by global coords by this scale factor? I'm assuming I can use container.worldTransform somehow, but I don't understand how to use this.

Answer 1

I ended up making two separate PIXI Containers: one for rotation, and an outer one for scaling. As suggested here: https://www.html5gamedevs.com/topic/46497-how-do-i-scale-a-graphics-object-by-global-coordinates-in-pixijs/?do=findComment&comment=255423
