html5源码教程
1、新建游戏项目文件目录
2、编写index.html文件源码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8"/>
<title>五子棋</title>
<link rel="stylesheet" type="text/css" href="css/style.css"/>
<script type="text/javascript" src="js/script.js"></script>
</head>
<body>
<canvas id="chess
<input type="button" onclick="window.location.reload();" value="在玩一次">
</body>
</html>
3、在css文件夹里新建css文件，style.css文件源码如下：
canvas{
display: block;
margin-left:400px;
margin-top: 60px;
box-shadow: -2px -2px 2px #EFEFEF, 5px 5px 5px #B9B9B9;
width: 450px; height: 450px;
}
input{float: right; display: block; margin-right:130px;margin-top: -250px;
width: 100px; height: 30px; font-size: 18px;
}
input:hover{ background-color:orange; color: #fefefe;}
4、在js文件夹里新建script.js文件，源码如下：
window.onload=function(){
var me=true;
var over=false;
var chessBord=[];
//初始化chessBord数组
for(var i=0; i<15;i++){
chessBord[i]=[];
for(var j=0;j<15;j++){
chessBord[i][j]=0;
}
}
//var me=[true];
//赢法数组
var wins=[];
var computerWin=[];
//赢法的统计数组
var myWin=[];
//初始化3维数组
for(var i=0; i<15; i++){
wins[i]=[];
for(var j=0; j<15; j++){
wins[i][j]=[];
}
}
var count=0;
for(var i=0;i<15;i++){
for(var j=0;j<11;j++){
for(var k=0;k<5;k++){
wins[i][j+k][count]=true;
}
count++;
}
}
for(var i=0;i<15;i++){
for(var j=0;j<11;j++){
for(var k=0;k<5;k++){
wins[j+k][i][count]=true;
}
count++;
}
}
for(var i=0;i<11;i++){
for(var j=0;j<11;j++){
for(var k=0;k<5;k++){
wins[i+k][j+k][count]=true;
}
count++;
}
}
for(var i=0;i<11;i++){
for(var j=14;j>3;j--){
for(var k=0;k<5;k++){
wins[i+k][j-k][count]=true;
}
count++;
}
}
console.log(count);
for(var i=0; i<count; i++){
myWin[i]=0;
computerWin[i]=0;
}
