Я новичок помогите.
 

У меня ошибка с гравитацией.Ничего на экран не выводит.
Ошибка - Uncaught ReferenceError: preload is not defined
Буду благодарен кто решит и объяснит что происходит.

var game = new Phaser.Game(800, 600, Phaser.AUTO, 'phaser-example', { preload: preload, create: create, render: render });
