Gravity Won't Work Properly

Ok, so I've noticed my game draws 2 sprites.. One with no physics enabled in the foreground.. And the second with gravity working, but it's behind my game background.


 


I've also noticed that when I implemented the gravity, it didn't use any X/Y coordinates, how do I make it change them?



var game = new Phaser.Game(1024, 512 , Phaser.CANVAS, 'phaser-example', { preload: preload, create: create, render: render, update: update });


var player;

var background1 =
{
x: 0,
y: 0
};

var background2 =
{
x: 1024,
y: 0
};

var playerX = 100;
var playerY = 40;

function preload()
{
game.load.image('playerImage', 'img/player.png');
game.load.image('backgroundImage', 'img/background.png');
}

function create()
{
game.physics.startSystem(Phaser.Physics.ARCADE);

// Set the world (global) gravity
game.physics.arcade.gravity.y = 350;

// Sprite 1 will use the World (global) gravity
game.add.sprite(background1);
game.add.sprite(background2);

player = game.add.sprite(100, 96, 'playerImage');

// Enable physics on those sprites
game.physics.enable(player, Phaser.Physics.ARCADE);

player.body.collideWorldBounds = true;
player.body.bounce.y = 0.1;
player.body.gravity.y = 200;
}

function render()
{
game.world.removeAll();

game.add.sprite(background1.x, background1.y, 'backgroundImage');
game.add.sprite(background2.x, background2.y, 'backgroundImage');

game.add.sprite(playerX, playerY, 'playerImage');
}

function jump()
{

}

function moveRight()
{

}

function moveLeft()
{

}

function updateBackground()
{
background1.x--;
background2.x--;

if(background1.x <= -1024)
{
background1.x = 1024;
}

if(background2.x <= -1024)
{
background2.x = 1024;
}
}

function update()
{
updateBackground();
}

Could you put your code into a Phaser sandbox, or JS Fiddle or anything that could help running / debugging it? I can't really figure out where the big bug is, but there obviously is one if it lags with so few lines of code.

 

EDIT : what is the size of your images?
