我們繼續這一系列文章，使用HTML5的canvas組件進行游戲開發。今天，這是相當完整的游戲例子 – 它會回顧經典的舊電腦游戲 – 坦克大戰。我會教你使用陣列地圖并教你如何檢測活動對象（坦克）與環境（基于陣列的地圖）的碰撞。

你可以點擊這里閱讀這一系列教程的前一篇文章： html5游戲制作入門系列教程（四）。我們的將基于之前的程序和代碼進行開發。

這里有我們的演示和下載包：

好吧，下載所需文件，讓我們開始編碼！

步驟1： HTML
這里是我演示的HTML，非常簡單，對不對？

        <!DOCTYPE html>
<html lang="en" >
<head>
<meta charset="utf-8" />
<title>html5游戲制作入門系列教程（五）</title>
<link href="css/main.css" rel="stylesheet" type="text/css" />
<script src="js/jquery-1.5.2.min.js"></script>
<script src="js/script.js"></script>
</head>
<body>
<header>
<h2>html5游戲制作入門系列教程（五）</h2>
<a  class="stuts">返回原文<span>HTML5GAME</span></a>
</header>

<div class="container">
<canvas id="scene" width="800" height="600"></canvas>
</div>
</body>
</html>

步驟2：CSS

下面是使用CSS樣式。
css/main.css
今天就不把css樣式貼出來了，和以前的一樣，沒有什么特別之處。你可以在下載包里找到它。

步驟3：JS
js/script.js

        // inner variables
var canvas, context; // canvas and context objects
var imgBrick, imgSteel, imgWater, imgForest, imgTank; // images
var aMap; // map array
var oTank; // tank object

var iCellSize = 24; // cell wide
var iXCnt = 26; // amount of X cells
var iYCnt = 26; // amount of Y cells

// objects :
function Tank(x, y, w, h, image) {
this.x = x;
this.y = y;
this.w = w;
this.h = h;
this.i = 0;
this.image = image;
}

// functions
function clear() { // clear canvas function
context.clearRect(0, 0, canvas.width, canvas.height);
}

function drawScene() { // main drawScene function
clear(); // clear canvas

// fill background
context.fillStyle = '#111';
context.fillRect(0, 0, canvas.width, canvas.height);

// save current context
context.save();

// walk through our array
for (var y = 0; y < iYCnt; y++) {
for (var x = 0; x < iXCnt; x++) {
switch (aMap[y][x]) {
case 0: // skip
break;
case 1: // draw brick block
context.drawImage(imgBrick, 0, 0, iCellSize, iCellSize, x*iCellSize, y*iCellSize, iCellSize, iCellSize);
break;
case 2: // draw steel block
context.drawImage(imgSteel, 0, 0, iCellSize, iCellSize, x*iCellSize, y*iCellSize, iCellSize, iCellSize);
break;
case 3: // draw forest block
context.drawImage(imgForest, 0, 0, iCellSize, iCellSize, x*iCellSize, y*iCellSize, iCellSize, iCellSize);
break;
case 4: // draw water block
context.drawImage(imgWater, 0, 0, iCellSize, iCellSize, x*iCellSize, y*iCellSize, iCellSize, iCellSize);
break;
}
}
}

// restore current context
context.restore();

// draw tank
context.drawImage(oTank.image, oTank.i*oTank.w, 0, oTank.w, oTank.h, oTank.x, oTank.y, oTank.w, oTank.h);
}
// -------------------------------------------------------------

// initialization
$(function(){
canvas = document.getElementById('scene');
canvas.width = iXCnt * iCellSize;
canvas.height = iYCnt * iCellSize;
context = canvas.getContext('2d');

// main scene Map array
