Is it possible in Phaser 3 to define the bounding box for each sprite frame into an atlas ? When I generate an sprite sheet into TexturePacker, we can find some parameters into the .json :

"idle-0001.png":

{

   "frame": {"x":1,"y":1,"w":423,"h":619},

   "rotated": false,

   "trimmed": false,

   "spriteSourceSize": {"x":1,"y":1,"w": 423,"h":619,

   "sourceSize": {"w":423,"h":619}

}

and my sprite definition :

this.sprite = scene.physics.add.sprite(x,y,'player-idle','idle-0001.png');

this.sprite.setCollideWorldBounds(true);

When i change spriteSourceSize or sourceSize, it doesn't change anything on my sprite is it normal ?

it is quite strange because the method setSize change well the bounding box. In the implementation of setSize the sourceSize is update so i think it is possible to set directly a bounding box with the atlas .json ?

/**

 * Sizes and positions this Body's boundary, as a rectangle.

 * Modifies the Body `offset` if `center` is true (the default).

 * Resets the width and height to match current frame, if no width and height provided and a frame is found.

 *

 * @method Phaser.Physics.Arcade.Body#setSize

 * @since 3.0.0

 *

 * @param {integer} [width] - The width of the Body in pixels. Cannot be zero. If not given, and the parent Game Object has a frame, it will use the frame width.

 * @param {integer} [height] - The height of the Body in pixels. Cannot be zero. If not given, and the parent Game Object has a frame, it will use the frame height.

 * @param {boolean} [center=true] - Modify the Body's `offset`, placing the Body's center on its Game Object's center. Only works if the Game Object has the `getCenter` method.

 *

 * @return {Phaser.Physics.Arcade.Body} This Body object.

setSize: function (width, height, center)

{

    if (center === undefined) { center = true; }



    var gameObject = this.gameObject;



    if (!width && gameObject.frame)

    {

        width = gameObject.frame.realWidth;

    }



    if (!height && gameObject.frame)

    {

        height = gameObject.frame.realHeight;

    }



    this.sourceWidth = width;

    this.sourceHeight = height;



    this.width = this.sourceWidth * this._sx;

    this.height = this.sourceHeight * this._sy;



    this.halfWidth = Math.floor(this.width / 2);

    this.halfHeight = Math.floor(this.height / 2);



    this.updateCenter();



    if (center && gameObject.getCenter)

    {

        var ox = gameObject.displayWidth / 2;

        var oy = gameObject.displayHeight / 2;



        this.offset.set(ox - this.halfWidth, oy - this.halfHeight);

    }



    this.isCircle = false;

    this.radius = 0;



    return this;
