I recommend a native JavaScript version of Lianliankan game to everyone, source code download, the homepage is as shown below:

First, take a look at the html layout in the index.html file:

Copy code The code is as follows:

>
Lianliankan




< div id="whole">






score


0


time


0




< ;/div>









The index.css file under the css folder is as follows:

Let’s take a look at the core js part implementation code. The js part is divided into three source files, namely game.js, map.js, and piece.js. The file corresponds to a class, in which this game uses the game class to manipulate map and picture piece objects:
The game.js code is as follows:



Copy codeThe code is as follows:

// Game control class
var Game = {
// Game background
gamePanel: null,
// Score
score: 0,
// Time
time: 0,
// Picture mapping table
pieceMap: null,
// Picture list
pieceList: [],
// Picture list does not contain pictures
pieceImgList: [],
// Picture random number list
randomList: [],
// Track list
trackList: [],
// Whether the game starts
isGameBigin : false,
// Whether the game is over
isGameOver: false,
// Whether the game is reset
isGameReset: false,
// Whether the picture element is clicked for the first time
isFirstClick : true,
//Start the game
start : function() {
document.getElementById("start").disabled = true;
document.getElementById("reset").disabled = false ;
if (this.isGameReset) {
this.isGameOver = false;

return;
} else if (this.isGameBegin) {

this.initImgPieces();
this.isGameBegin = true;
},
// Will randomly generate Add 150 pictures to the canvas
initPieces: function() {
var _this = this;
this.initRandomList();
// Disrupt the random list sorting
this.messRandomList() ;
for (var i = 0; i < 204; i ) {
var piece = new Piece(this);
this.pieceList.push(piece);
var x = ( i );
var y = Math.floor(i/17);
this.pieceMap.put(x "," y, piece);
piece.setPosition(x, y);
this.gamePanel.appendChild(piece.dom);

piece.track.className = "track";
piece.dom.appendChild(piece.track);
piece.isTracked = true;
continue;
} else {
if (x == 1 || x == 15 || y == 1 || y == 10) {
piece.setAtEdge(true);
}
this.pieceImgList.push(piece);
}
}
},
// Initialize pictures
initImgPieces: function() {
for (var i = 0; i < this.pieceImgList.length; i ) {
this.pieceImgList[i].initImg();
this.pieceImgList[i].img.src = "img/pieces/" this.randomList[i ] ".gif"
this.pieceImgList[i].setImgSrc(this.pieceImgList[i].img.src);
// Execute image click event
this.pieceImgList[i].onClick( ; i < 75; i ) {
var random = parseInt(Math.random()*22*10000, 10);
var number = random#;
this.randomList.push(number);
this.randomList.push(number);
}
},
//Shuffle the random table
messRandomList: function() {

var temp;

this.randomList[i] = this.randomList[number];
this.randomList[number] = temp;
}
},
//Start timing

document.getElementById("time").innerHTML = this.time;

clear : function() {

this.pieceList = [];
this.randomList = [];
this.pieceImgList = [];
this .isGameOver = true;

}
}
window.onload = function() {

document.getElementById("reset").disabled = true;
}
// Game start entry
function Start() {
Game.start();
}

function Reset() {

}


The customized js version mapping structure map.js source file is as follows :

The above is the code of the source file. For the specific implementation code, please pay attention to zhangjinpeng66 download in CSDN. Let’s talk about the core part of the Lianliankan game, the search path implemented in js.
JS implementation of the search path algorithm is first and simplest to determine whether two pictures can reach the function code in a straight line as follows:
Copy code The code is as follows:

// Straight line
isStraightReach: function(piece) {
//alert("isStraightReach");
if (this.isNear(piece)) {
return true;
}
var a = false;
var b = false;
// Search along the y-axis direction
if (this.x == piece.x ) {
//alert("!!!!!!!!!!!");
for (var i = this.min(this.y, piece.y) 1; i < this .max(this.y, piece.y); i ) {
//alert("this.x == piece.x: " piece.x "," i);
if (this.game .pieceMap.get(piece.x "," i).isPass()) {
a = true;
this.game.trackList.push(this.game.pieceMap.get(piece.x ", " i));
continue;
} else {
a = false;
this.game.trackList = [];
return a;
}
}
}
// Search along the x-axis direction
if (this.y == piece.y) {
//alert("!!!!!!!!!!!!");
for (var i = this.min(this.x, piece.x) 1; i < this.max(this.x, piece.x); i ) {
//alert("this .y == piece.y: " i "," piece.y);
if (this.game.pieceMap.get(i "," piece.y).isPass()) {
b = true;
this.game.trackList.push(this.game.pieceMap.get(i "," piece.y));
continue;
} else {
b = false
this.game.trackList = [];
return b;
}
}
}
return a || b;
},

This function implements the simplest step of Lianliankan to determine whether two pictures meet the connection conditions, and then performs a round-the-clock search.
Copy code The code is as follows:

// Search around a corner
isReach1: function (piece) {
//alert("isReach1");
var corner_1 = this.game.pieceMap.get(this.x "," piece.y);
var corner_2 = this.game .pieceMap.get(piece.x "," this.y);
var _this = this;
if ((_this.isStraightReach(corner_1))
&& (corner_1.isStraightReach(piece))
&& corner_1.isPass()) {
//alert("corner_1: " this.x "," piece.y);
this.game.trackList.push(corner_1);
return true;
}
if ((_this.isStraightReach(corner_2))
&& (corner_2.isStraightReach(piece))
&& corner_2.isPass()) {
//alert(" corner_2: " piece.x "," this.y);
this.game.trackList.push(corner_2);
return true;
}
return false;
},

The direct search function is called in the function of turning once and searching. Similarly, the most complex search of turning twice will also call the function of searching once.
Copy code The code is as follows:

// Turn twice to search
isReach2: function(piece) {
// Search forward along the x-axis
for (var i = this.x 1; i < 17; i ) {
if (!this.game.pieceMap.get (i "," this.y).isPass()) {
this.game.trackList = [];
break;
} else if (this.game.pieceMap.get(i ", " this.y).isReach(piece)
&& this.game.pieceMap.get(i "," this.y).isPass()) {
this.game.trackList.push(this.game .pieceMap.get(i "," this.y));
return true;
}
}
// Search along the x-axis
for (var i = this.x - 1; i >= 0; i --) {
if (!this.game.pieceMap.get(i "," this.y).isPass()) {
this.game.trackList = [];
break;
} else if (this.game.pieceMap.get(i "," this.y).isReach(piece)
&& this.game.pieceMap.get(i " ," this.y).isPass()) {
this.game.trackList.push(this.game.pieceMap.get(i "," this.y));
return true;
}
}
// Search along the y-axis
for (var i = this.y - 1; i >= 0; i --) {
if (!this.game.pieceMap .get(this.x "," i).isPass()) {
this.game.trackList = [];
break;
} else if (this.game.pieceMap.get(this .x "," i).isReach(piece)
&& this.game.pieceMap.get(this.x "," i).isPass()) {
this.game.trackList.push(this .game.pieceMap.get(this.x "," i));
return true;
}
}
// Search forward along the y-axis
for (var i = this.y 1; i < 12; i ) {
if (!this.game.pieceMap.get(this.x "," i).isPass()) {
this.game.trackList = [];
break;
} else if (this.game.pieceMap.get(this.x "," i).isReach(piece)
&& this.game.pieceMap.get(this. x "," i).isPass()) {
this.game.trackList.push(this.game.pieceMap.get(this.x "," i));
return true;
}
}
return false;
},

This function starts the search along the x-axis and y-axis with the clicked image as the center.
