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：

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aiRequestfunction 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judgeArrayfor (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; }到此，相信大家对“如何使用JavaScript做一款无框架浏览器直接运行的数字棋牌小游戏”有了更深的了解，不妨来实际操作一番吧！这里是编程网网站，更多相关内容可以进入相关频道进行查询，关注我们，继续学习！
