本文实例为大家分享了js实现简单拼图游戏的具体代码,供大家参考,具体内容如下
HTML仅有一个id为game的div,并且没有编写css样式,只需要在img文件夹中放置一个图片文件就行,此处我放置的是LOL皇子的图片,图片名为'lol.png'
<div id="game">
</div>
以下为实现后的效果图
多的不说,直接上js代码
var gameConfig = {
width: 500,
height: 500,
rows: 3, //行数
cols: 3, //列数
isOver: false, //游戏是否结束
imgurl: "img/lol.png", //图片路径,注意:相对的是页面路径
dom: document.getElementById("game") //游戏的dom对象
};
//每一个小块的宽高
gameConfig.pieceWidth = gameConfig.width / gameConfig.cols;
gameConfig.pieceHeight = gameConfig.height / gameConfig.rows;
//小块的数量
gameConfig.pieceNumber = gameConfig.rows * gameConfig.cols;
var blocks = []; //包含小方块信息的数组
function isEqual(n1, n2) {
return parseInt(n1) === parseInt(n2);
}
function Block(left, top, isVisible) {
this.left = left; //当前的横坐标
this.top = top; //当前的纵坐标
this.correctLeft = this.left; //正确的横坐标
this.correctTop = this.top; //正确的纵坐标
this.isVisible = isVisible; //是否可见
this.dom = document.createElement("div");
this.dom.style.width = gameConfig.pieceWidth + "px";
this.dom.style.height = gameConfig.pieceHeight + "px";
this.dom.style.background = `url("${gameConfig.imgurl}") -${this.correctLeft}px -${this.correctTop}px`;
this.dom.style.position = "absolute";
this.dom.style.border = "1px solid #fff";
this.dom.style.boxSizing = "border-box";
this.dom.style.cursor = "pointer";
// this.dom.style.transition = ".5s"; //css属性变化的时候,在0.5秒中内完成
if (!isVisible) {
this.dom.style.display = "none";
}
gameConfig.dom.appendChild(this.dom);
this.show = function () {
//根据当前的left、top,重新设置div的位置
this.dom.style.left = this.left + "px";
this.dom.style.top = this.top + "px";
}
//判断当前方块是否在正确的位置上
this.isCorrect = function () {
return isEqual(this.left, this.correctLeft) && isEqual(this.top, this.correctTop);
}
this.show();
}
function init() {
//1. 初始化游戏的容器
initGameDom();
//2. 初始化小方块
//2.1 准备好一个数组,数组的每一项是一个对象,记录了每一个小方块的信息
initBlocksArray();
//2.2 数组洗牌
shuffle();
//3. 注册点击事件
regEvent();
function regEvent() {
//找到看不见的方块
var inVisibleBlock = blocks.find(function (b) {
return !b.isVisible;
});
blocks.forEach(function (b) {
b.dom.onclick = function () {
if (gameConfig.isOver) {
return;
}
//判断是可以交换
if (b.top === inVisibleBlock.top &&
isEqual(Math.abs(b.left - inVisibleBlock.left), gameConfig.pieceWidth)
||
b.left === inVisibleBlock.left &&
isEqual(Math.abs(b.top - inVisibleBlock.top), gameConfig.pieceHeight)) {
//交换当前方块和看不见的方块的坐标位置
exchange(b, inVisibleBlock);
//游戏结束判定
isWin();
}
//交换当前方块和看不见的方块的坐标位置
// exchange(b, inVisibleBlock);
// //游戏结束判定
// isWin();
}
})
}
function isWin() {
var wrongs = blocks.filter(function (item) {
return !item.isCorrect();
});
if (wrongs.length === 0) {
gameConfig.isOver = true;
//游戏结束,去掉所有边框
blocks.forEach(function (b) {

});
}
}
function getRandom(min, max) {
return Math.floor(Math.random() * (max + 1 - min) + min);
}
function exchange(b1, b2) {
var temp = b1.left;
b1.left = b2.left;
b2.left = temp;
temp = b1.top;
b1.top = b2.top;
b2.top = temp;
b1.show();
b2.show();
}
function shuffle() {
for (var i = 0; i < blocks.length - 1; i++) {
//随机产生一个下标
var index = getRandom(0, blocks.length - 2);
//将数组的当前项与随机项交换left和top值
exchange(blocks[i], blocks[index]);
}
}
function initBlocksArray() {
for (var i = 0; i < gameConfig.rows; i++) {
for (var j = 0; j < gameConfig.cols; j++) {
//i 行号,j 列号
var isVisible = true;
if (i === gameConfig.rows - 1 && j === gameConfig.cols - 1) {
isVisible = false;
}
var b = new Block(j * gameConfig.pieceWidth, i * gameConfig.pieceHeight, isVisible);
blocks.push(b);
}
}
}
function initGameDom() {
gameConfig.dom.style.width = gameConfig.width + "px";
gameConfig.dom.style.height = gameConfig.height + "px";
gameConfig.dom.style.border = "2px solid #ccc";
