Let’s take a look at the core js part implementation code. The js part is divided into three source files: game Each source file of .js, map.js, and piece.js corresponds to a class. This game uses the game class to manipulate map and picture piece objects:
game.js code is as follows:
[javascript]
// Game control class
var Game = {
// Game background
gamePanel: null,
// Score
Score : 0,
// Time
time: 0,
// Picture map
pieceMap: null,
// Picture list
pieceList: [],
pieceimglist: [],
// Picture random number list
randomlist: [],
// trajectory list
tracklist: [],
// whether the game starts
isgamebigin: false,
// Whether the picture element is clicked for the first time isFirstClick: true, GetElementById ( "). elementById("reset").disabled = false;
reset : function() {
document.getElementById("start").disabled = false; document.getElementById("reset"). document.getElementById("reset").disabled = document.getElementById("reset").
this.initPieces(); this.initImgPieces(); this.time = 0; document.getElementById("time").innerHTML = 0; this.score = 0; document.getElementById("score"). innerHTML = 0; this.isGameReset = true;// Initialization
init : function() {
if (this .isGameBegin) {
var _this = this;
this.time = 0;
This.gamePanel = document.getElementById("pieces");
This.initPieces(); this.initImgPieces(); This.isGameBegin = true;
},
机 随 // Add the randomly generated 150 pictures into the canvas Initpieces: Function () { var _This = this; this.initrandomList (); Random list sorting this.messRandomList(); var piece = new Piece(this); this.pieceList .push(piece); var x = (i%17); var y = Math.floor(i/17); This.pieceMap.put(x+","+y, piece); piece.setPosition(x, y); if (x == 0 || x == 16 || y == 0 || y == 11) {piece.dom.appendChild(piece.track) ;
piece.isTracked = true; ) {
e piece.Setatedge (true);
}
this.pieceimglist.push (piece);
// Initialize pictures initImgPieces : function() { This.pieceImgList[i].initImg ();This.pieceImgList[i].img.src = "img/pieces/"+this.randomList[i]+".gif"
This.pieceImgList[i].setImgSrc(this.pieceImgList[i].img. src);
function() { Int(Math.random() *22*10000, 10); var number = random%23; this.randomList.push(number); this.randomList.push(number); parseInt(Math.random()*15*10000, 10); var number = random%150; var temp; temp = this.randomList [i]; this.randomList[i] = this.randomList[number]; this.randomList[number] = temp; } } },var _this = this;
} else {
. innerHTML = this.time;
this.isGameBegin = true;
setTimeout(function() {_this.startTime();}, 1000);
}
Clear
clear : function() {
for (var i = 0; i < this.pieceList.length; i ++) {
i] .dom);
this.pieceImgList = []; this.isGameOver = true; this.isGameBegin = false; ElementById("start").disabled = false;document.getElementById("reset").disabled = true;
}
// Game start entrance
function Start() {
Game.start();
}
// Game reset entry
function Reset() {
Game.reset();
}
Customized js version mapping structure map.js The source file is as follows:
[javascript]
var Map = function(){
this.data = [];
}
M ap.prototype = {
put : function(key, value) {
return this.data[key]; },
isEmpty : function() {
return this.data .length == 0;
},
size: function() {
} return this.data.length;
}
pictures The source file of class piece.js is as follows:
[javascript]
var Piece = function(game) {
// Game object
this.game = game;
// Is it an edge? Element
this.isEdge = false;
// Whether it is next to the edge element
this.atEdge = false;
// Image dom element
this.dom = null;
/ / Image element
this.img = null;
// Image element source
this.src = null;
// Track element
this.track = null;
// Whether it can be used as a track
This.isTracked = false;
// Check mark element
this.selected = null;
// Pictures arranged horizontally This.x = 0;
// Pictures are arranged vertically
this.y = 0;
// Picture flash Id
this.flashId = null;
// Whether the picture is clicked
this.onClicked = false;
// Number of flashes
this.flashCount = 0;
this.init();
}
Piece.prototype = {
// Initialization
init : function( ) {
This.dom = document.createElement("div");
this.dom.className = "piece"; createElement("img");
