Cannot read property 'getImage' of undefined

[robkof]

Hi!

Im new to Javascript game programming and Phaser.

I am running in to a problem when i try to create a class which inherits from Phaser.Sprite

So I load my image: 

this.load.image('face','assets/face.jpg')

 

I create the class (from the official Monsterbunny example):

Enemy = function (game, x, y, spritename) {
    Phaser.Sprite.call(this, game, x, y, spritename);

    this.anchor.setTo(0.5, 0.5);

    this.scale.setTo(1, 1)

    game.add.existing(this);

};

Enemy.prototype = Object.create(Phaser.Sprite.prototype);
Enemy.prototype.constructor = Enemy;

Enemy.prototype.update = function () {

};

And then add it to the game with:

new Enemy(game,500,500,'face')

But when the code runs, I get error msg: 

Quote

Uncaught TypeError: Cannot read property 'getImage' of undefined

At the line of which the Phaser.Sprite.call(this, game, x, y, spritename);

I have the newest version of Phaser.

Thx for all the help in advance!
