Class hierarchy and arcade physics doesn't work

[Todi]

Guys, I fixed my code that was causing error, but, the collision  between Sprite and TileSprite doesn't work yet. Here is the code:

Game.prototype.update = function () {    this.game.physics.arcade.collide(this._player, this._ground);};

Anyone know what is going on?

 

Thank you all!

For those who don't found it yet, follow the code that I was forgetful:

// box collision sizethis.body.setSize(width, height - 480, x, 480);

Set the size of your TileSprite and it will collide!

 

Sorry the double post!
