How can I scale the size of a sprite in Phaser/PixiJS without changing its position?

Question

I'm making a game in Phaser using some large images that I want to scale down in the actual game:

create() {
    //Create the sprite group and scale it down to 30%
    this.pieces = this.add.group(undefined, "pieces", true);
    this.pieces.scale.x = 0.3;
    this.pieces.scale.y = 0.3;

    //Add the players to the middle of the stage and add them to the 'pieces' group
    var middle = new Phaser.Point( game.stage.width/2, game.stage.height/2);
    var player_two = this.add.sprite(middle.x - 50, middle.y, 'image1', undefined, this.pieces);
    var player_one = this.add.sprite(middle.x, middle.y-50, 'image2', undefined, this.pieces);
}

However because the sprites are scaled in size, their starting location is also scaled, so instead appearing in the middle of the stage, they appear only 30% of the distance to the middle.

How do I scale the sprite image without it affecting their location?

(The code is incidentally in Typescript but I think this particular sample is also javascript so that's probably irrelevant)

Answer 1

Set Sprite.anchor to 0.5 so the physics body is centered on the Sprite, scale the sprite image without it affecting their location.

this.image.anchor.setTo(0.5, 0.5);
