Description

When a Matter.Image, configured with a physic shape, is scaled on X then on Y or vice versa, the shape become distorted.
It seems that the second scale apply again the first one.

class Actor extends Phaser.Physics.Matter.Image {
    constructor(scene, x, y, texture) {
    super(scene.matter.world, x, y, texture, 0, {
        shape: scene.fixtures[texture]
    });

    // ....

}

let gem = new Actor(this, 100, 400, 'Gem Blue');
gem.scaleX = 0.5;
// here everything is ok
gem.scaleY = 0.5;
// here the shape x is resized again

give that (with debug mode activated) :

• With scaleX = 0.5 then scaleY = 0.5
  

• With scaleY=0.5 then scaleX = 0.5
  

turn around

Use setScale(0.5, 0.5) instead.

words

Many thanks to Phaser and matterjs teams that give us so valuable tools.
Cheers.
