Create a ball game in HTML5 and JQuery



Today i am going to tell you ,how you can make a simple game in html and jquery. HTML5 has introduced canvas tag that allow you to drow different shapes in an html page.

<canvas id="myCanvas" width="200" height="100"
style="border:1px solid #000000;">
</canvas>

Using this html canvas tag and jquery we will make simple ball game.Firstly i will show you main parts of code.

Lets start with html code.Copy below code and save in file with .html extension.

<!DOCTYPE html>
<html>
<head>
</head>
<body >

<div style="border:solid 5px;height:100%">

<canvas id="mybar1" width="150" height="25" style="padding:5px;bottom:0px;left:10px;position:absolute">
Your browser does not support the HTML5 canvas tag.
</canvas>
<canvas id="myCanvas" width="1300" height="600">
  </canvas>
</div>
<div id="watermark"><p><center>Game By Money</center></p></div>
</body>
</html>

Now lets add some life to code by adding some js.

<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
var a=0;
var maxy=$("div").width();
var maxx=$("div").height();
var c=document.getElementById("mybar1");
var ctx=c.getContext("2d");
ctx.fillStyle="#FF0000";
ctx.fillRect(0,0,150,25);
var c=document.getElementById("myCanvas");
var context;
var x=maxy;
var y=maxx;
var dx=5;
var dy=5;

function init()
{
  context= myCanvas.getContext('2d');
  setInterval(draw,10);
}

function draw()
{
  context.clearRect(0,0, maxy,maxx);
  context.beginPath();
  context.fillStyle="#0000ff";
  // Draws a circle of radius 20 at the coordinates 100,100 on the canvas
  context.arc(x,y,20,0,Math.PI*2,true);
  context.closePath();
  context.fill();
  // Boundary Logic
if( x<0 || x>maxy) dx=-dx; 
if( y<0 || y>maxx) dy=-dy; 
var position=$("#mybar1").offset();
if (x < position.left + 150  && x + 40  > position.left &&
    y < position.top + 25 && y + 40 > position.top) {
// The objects are touching
dy=-dy;
}
x+=dx; 
y+=dy;
if(y>maxx)
alert("Game Over");
}
$(document).keydown(function(e) {
    switch (e.which) {
    case 37:
    if(a>25){
    a=a-25;
    document.getElementById("mybar1").style.left =  a + "px";
    }
    break;
    case 39:
    if(a+170<maxy){
    a=a+25;
    document.getElementById("mybar1").style.left =  a + "px";
    }
    break;
    }
});
</script>

Now we give some colors to game adding css.

<style type="text/css">
#watermark {
  color: #d0d0d0;
  font-size: 100pt;
  position: absolute;
  width: 50%;
  height: 50%;
  margin: 0;
  z-index: -1;
  left:350px;
  top:0px;

Now we have understood all main parts of coding.

Below is the full code:

<!DOCTYPE html>
<html>
<head>

<style type="text/css">
#watermark {
  color: #d0d0d0;
  font-size: 100pt;
  position: absolute;
  width: 50%;
  height: 50%;
  margin: 0;
  z-index: -1;
  left:350px;
  top:0px;
}
</style>

</head>
<body onLoad="init();" style="position: absolute;
height: 93%;
top: 0px;
bottom: 0px;
width: 98%;">

<div style="border:solid 5px;height:100%">

<canvas id="mybar1" width="150" height="25" style="padding:5px;bottom:0px;left:10px;position:absolute">
Your browser does not support the HTML5 canvas tag.
</canvas>
<canvas id="myCanvas" width="1300" height="600">
  </canvas>
</div>
<div id="watermark"><p><center>Game By Money</center></p></div>
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script>
var a=0;
var maxy=$("div").width();
var maxx=$("div").height();
var c=document.getElementById("mybar1");
var ctx=c.getContext("2d");
ctx.fillStyle="#FF0000";
ctx.fillRect(0,0,150,25);
var c=document.getElementById("myCanvas");
var context;
var x=maxy;
var y=maxx;
var dx=5;
var dy=5;

function init()
{
  context= myCanvas.getContext('2d');
  setInterval(draw,10);
}

function draw()
{
  context.clearRect(0,0, maxy,maxx);
  context.beginPath();
  context.fillStyle="#0000ff";
  // Draws a circle of radius 20 at the coordinates 100,100 on the canvas
  context.arc(x,y,20,0,Math.PI*2,true);
  context.closePath();
  context.fill();
  // Boundary Logic
if( x<0 || x>maxy) dx=-dx; 
if( y<0 || y>maxx) dy=-dy; 
var position=$("#mybar1").offset();
if (x < position.left + 150  && x + 40  > position.left &&
    y < position.top + 25 && y + 40 > position.top) {
// The objects are touching
dy=-dy;
}
x+=dx; 
y+=dy;
if(y>maxx)
alert("Game Over");
}
$(document).keydown(function(e) {
    switch (e.which) {
    case 37:
    if(a>25){
    a=a-25;
    document.getElementById("mybar1").style.left =  a + "px";
    }
    break;
    case 39:
    if(a+170<maxy){
    a=a+25;
    document.getElementById("mybar1").style.left =  a + "px";
    }
    break;
    }
});
</script>

</body>
</html>
