一、游戏效果展示
二、游戏逻辑与交互设计
由于技术有限不能做太复杂的游戏，所以做个休闲数字游戏是比较合适的，下手之前做了挺多准备，包括思考游戏逻辑、收集和制作游戏图片、音乐素材等，最后确定要完成一下几个游戏必备的内容。
（一）游戏逻辑
游戏玩法就是在原来“井字过三关”游戏的基础上加上数字计算，三连子后同时计算个位数大小，谁大就谁赢。
（二）人机交互
游戏为双人游戏，分为蓝方（AI）和红方（玩家），双方一开始各自获得5个随机分配的棋子，棋子包含个位数字。抛骰子后，玩家按先后顺序拖动棋子放入棋盘中。每次游戏都可实时计算得分，每盘游戏结束后记录得分，具有历史排行榜功能。
（三）游戏界面设计
游戏以卡通为主，收集制作素材尽量为可爱风格。支持英语、日语、简体中文、繁体中文。
（四）游戏音乐设计
游戏要有背景音乐、下棋声音、胜负声音、并可以按需关闭声音。
二、游戏制作过程
（一）游戏资源收集和制作
先在纸上画出草图，然后网上收集素材制作棋盘、棋子等贴图，最后全部放在一个img文件夹并命名编号，用于后续JavaScript调用。
（二）游戏布局
使用HTML+CSS代码，将Img文件夹中的贴图元素按设计的布局放置在对应的位置中，并设置z-index属性，用于控制元素的显示与隐藏。HTML代码如下：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<meta name="format-detection"content="telephone=no"/>
<meta name="msapplication-tap-highlight"content="no"/>
<meta name="viewport"content="user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0"/>
<meta http-equiv="Content-Security-Policy"content="default-src * 'unsafe-inline'; style-src 'self' 'unsafe-inline'; media-src *"/>
<link href="https://www.maopiaopiao.com">CSS的代码如下，主要用于设置共同的样式属性和部分元素的移动、弹出、消失动画。
* { -webkit-tap-highlight-color: rgba(0, 0, 0, 0); /* make transparent link selection, adjust last value opacity 0 to 1.0 */ }
body { -webkit-touch-callout: none; /* prevent callout to copy image, etc when tap to hold */ -webkit-text-size-adjust: none; /* prevent webkit from resizing text to fit */ -webkit-user-select: none; /* prevent copy paste, to allow, change 'none' to 'text' */ overflow: hidden; }

1.通过JavaScript的.addEventListener()为div棋子元素添加选中、拖动、放入，触发对应mousedown、mousemove、mouseup事件的响应函数。
为div元素添加事件响应函数，代码如下：
document.getElementById("h3_" + i).addEventListener('mouseup', outmouse);
document.getElementById("h3_" + i).addEventListener('mousemove', movemouse);
document.getElementById("h3_" + i).addEventListener('mousedown', selectmouse);为div元素实现拖放效果，代码如下：
//玩家棋子拖拽移动回调函数
function movemouse(e) {
if (isdrag) {
var n = thx + e.pageX- hx;
var m = thy + e.pageY - hy;
$("#h3_" + parseInt(e.target.id)).css({
"left": n,
"top": m
});
hx1 = e.pageX;
hy1 = e.pageY;
return false;
}
}2.使用audio元素，为游戏添加音效，载入游戏音频文件、播放音频代码如下：
btn_media = document.createElement("audio");
btn_media.src = "media/btn09.mp3";
btn_media.play()3.使用二维数组存放双方棋子，用于判断双方下棋后剩余棋子的情况，a[][0]代表手牌数值，a[][1]代表手牌状态，主要代码如下：
//玩家与电脑的手牌，a[][0]代表手牌数值，a[][1]代表手牌状态
var AIHand = new Array([5][2]);
var playerHand = new Array([5][2]);
for (var k = 0; k < 5; k++) {
AIHand[k] = new Array();
for (var j = 0; j < 2; j++) {
AIHand[k][j] = "";
}
}
for (var k = 0; k < 5; k++) {
playerHand[k] = new Array();
for (var j = 0; j < 2; j++) {
playerHand[k][j] = "";
}
}4.使用二维数组存放棋局，用于判断实时得分以及控制AI下棋，主要代码如下：
//记录手牌的棋盘
var gameChessBoardForHand = new Array([3][3]);
for (var k = 0; k < 3; k++) {
gameChessBoardForHand[k] = new Array();
for (var j = 0; j < 3; j++) {
gameChessBoardForHand[k][j] = 0;
}
}5.编写简单AI算法，自动下棋，目前原理只是有空位就放。
// AI思考，返回AI的操作aiRequest
function discard() {
var aiRequest = new Array();
//复制棋盘
var cloneChessBoard = new Array([3][3]);
for (var k = 0; k < 3; k++) {
cloneChessBoard[k] = new Array();
for (var j = 0; j < 3; j++) {
cloneChessBoard[k][j] = 0;
}
}
for (var k = 0; k < 3; k++) {
for (var j = 0; j < 3; j++) {
cloneChessBoard[k][j] = parseInt(gameChessBoard[k][j]);
}
}
aiRequest[0] = -1;
aiRequest[1] = -1;
aiRequest[2] = -1;
//模拟玩家走一步
var miniGameState = 9;
for (var k = 0; k < 5; k++) {
//如果玩家手牌可以出
if (AIHand[k][1] > 0) {
for (var i = 0; i < 3; i++) {
for (var j = 0; j < 3; j++) {
if (cloneChessBoard[i][j] == 0) {
cloneChessBoard[i][j] = AIHand[k][0] + 1000;
var gameState = judgeGameCong(cloneChessBoard);
//console.log(gameState);
if (gameState[0] % 10 < gameState[2] % 10) {
aiRequest[0] = i;
aiRequest[1] = j;
if ((gameState[2] % 10) <= miniGameState && (gameState[2] % 10) != -1) {
miniGameState = gameState[2] % 10;
aiRequest[2] = k;
}
//aiRequest[2]=k; BUG1用了玩家的手牌位置来出
}
cloneChessBoard[i][j] = 0;
}
}
}
}
}
var enableChessBoard = new Array();
//没有找到解则
if (aiRequest[0] == -1) {
for (var i = 0; i < 3; i++) {
for (var j = 0; j < 3; j++) {
if (cloneChessBoard[i][j] == 0) {
enableChessBoard.push(i * 3 + j);
//aiRequest[0] = i;
//aiRequest[1] = j;
}
}
}
var randomNum = getRandom(enableChessBoard.length - 1);
var i = Math.floor(enableChessBoard[randomNum] / 3);
var j = enableChessBoard[randomNum] % 3;
console.log(randomNum, i, j, randomNum, enableChessBoard.length);
aiRequest[0] = i;
aiRequest[1] = j;
for (var i = 0; i < 5; i++) {
if (AIHand[i][1] > 0) {
aiRequest[2] = i;
}
}
}
return aiRequest;
}6.判断输赢，把结果存入全局变量gameState中，主要代码如下：
// 判断游戏胜负
function judgeGameCong(chessboard) {
var judgeArray = new Array([8][3]);
//gameState[0-3]分别代表电脑得分、电脑三连子位置、玩家得分、玩家三连子位置
var gameState = new Array(-1, -1, -1, -1);
//将棋盘横竖、对角线8个数组存入judgeArray
for (var g = 0; g < 3; g++) {
judgeArray[g] = new Array();
for (var j = 0; j < 3; j++) {
judgeArray[g][j] = chessboard[g][j];
}
}
for (var g = 3, k = 0; g < 6; g++, k++) {
judgeArray[g] = new Array();
for (var j = 0; j < 3; j++) {
judgeArray[g][j] = chessboard[j][k];
}
}
judgeArray[6] = new Array();
judgeArray[6][0] = chessboard[0][0];
judgeArray[6][1] = chessboard[1][1];
judgeArray[6][2] = chessboard[2][2];
judgeArray[7] = new Array();
judgeArray[7][0] = chessboard[0][2];
judgeArray[7][1] = chessboard[1][1];
judgeArray[7][2] = chessboard[2][0];
//遍历judgeArray,并将最高分与数组位置存入gameState,其中gameState[0-3]分别代表电脑得分、电脑三连子位置、玩家得分、玩家三连子位置
for (var i = 0; i < 8; i++) {
var x = parseInt(judgeArray[i][0] / 1000);
var y = parseInt(judgeArray[i][1] / 1000);
var z = parseInt(judgeArray[i][2] / 1000);
var a = parseInt(judgeArray[i][0]) + parseInt(judgeArray[i][1]) + parseInt(judgeArray[i][2]);
if ((x == y) && (x == z) && (x != 0)) {
if (x == 1) {
if ((a % 10) >= (gameState[0] % 10)) {
gameState[0] = a;
gameState[1] = i;
}
} else {
if ((a % 10) >= (gameState[2] % 10)) {
gameState[2] = a;
gameState[3] = i;
}
}
}
}
// console.log(gameState);
return gameState;
}
