This is what I got so far, and it's not working at all :(
<!DOCTYPE html>
<html lang="en">
<head>
<title>Class Test</title>
<meta charset="utf-8" />
<style>
body { text-align: center; background-color: #ffffff;}
#box { position: absolute; left: 610px; top: 80px; height: 50px; width: 50px; background-color: #ff0000; color: #000000;}
</style>
<script type="text/javascript">
document.onkeydown=function(event){keyDown(event)};
document.onkeyup=function(event){keyUp(event)};
var box = 0;
function Player () {
var speed = 5;
var x = 50;
var y = 50;
}
function update() {
box.style.left = this.x + "px";
box.style.top = this.y + "px";
box.innerHTML = "<h6 style=\"margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px;\">X: "+ this.x + "<br /> Y: " + this.y + "</h6>";
}
var player = new Player();
var keys = new Array(256);
var i = 0;
for (i = 0;i <= 256; i++){
keys[i] = false;
}
function keyDown(event){
keys[event.keyCode] = true;
}
function keyUp(event){
keys[event.keyCode] = false;
}
function update(){
if(keys[37]) player.x -= player.speed;
if(keys[39]) player.x += player.speed;
player.update();
}
setInterval(update, 1000/60);
</script>
</head>
<body>
<div id="box" ></div>
<script type="text/javascript">
box = document.getElementById('box');
box.innerHTML = "<h6 style=\"margin: 0px 0px 0px 0px; padding: 0px 0px 0px 0px;\">X: "+ player.x + "<br /> Y: " + player.y + "</h6>";
