代码分析:
1初始化;进入游戏,初始化4*4表格,并随机产生两个2;
# 二维数组this.tables表格循环存入数据
#random1, random2 ,random11, random22四个随机数可以确定两个2的xy位置;
#方法newNumber里面,根据位置i,j和级别num可以确定一个新的数字;创建背景cell和cell上面的数字标签cellLabel;并根据num确定是否显示cellLabel;最后给cell关联一个data数据;特别说明这里的number:num不是精灵上面的数字而是精灵的级别,比如number=11 则数字是1024
- MainLayer.prototype.onEnter = function () {
- //version
- this.versionNum = indexVersions;
- this.indexVersion = VERSIONS[this.versionNum];
- this.title.setString(this.indexVersion.name + "目标:" + this.indexVersion.array[this.indexVersion.array.length - 1] + "");
- var random1 = getRandom(4);
- var random2 = getRandom(4);
- while (random1 == random2) {
- random2 = getRandom(4);
- }
- var random11 = getRandom(4);
- var random22 = getRandom(4);
- this.tables = new Array(4);
- for (var i = 0; i < 4; i++) {
- var sprites = new Array(4);
- for (var j = 0; j < 4; j++) {
- if (i == random1 && j == random11) {
- sprites[j] = this.newNumber(i, j, 1);
- } else if (i == random2 && j == random22) {
- sprites[j] = this.newNumber(i, j, 1);
- } else {
- sprites[j] = this.newNumber(i, j, 0);
- }
- }
- this.tables[i] = sprites;
- }
- this.totalScore = 0;
- };
- MainLayer.prototype.newNumber = function (i, j, num) {
- var cell = cc.MySprite.create(this.rootNode, "5.png", this.getPosition(i, j), 1);
- var cellLabel = cc.MySprite.createLabel(cell, "");
- if (num > 0) {
- cell.setColor(COLOR[num]);
- cellLabel.setVisible(true);
- cellLabel.setString(this.indexVersion.array[num]);
- cellLabel.setFontSize(this.indexVersion.labelFontSize);
- } else {
- cellLabel.setVisible(false);
- }
- cell.data = {col: i, row: j, numberLabel: cellLabel, number: num};
- return cell;
- };
2 四个方向算法;玩游戏的时候触摸四个方向,表格就向四个方向合并靠拢leftCombineNumber,rightCombineNumber,downCombineNumber,upCombineNumber,四个方法函数的算法都是一样的,我只分析一个leftCombineNumber;
第一步 相同数据叠加 :
#j从左到右变大,i从下到上变大;也就初始位置是左下角;
#如果该单元格级别不是空背景 cell.data.number != 0 ;
#从它的右边开始var k = i + 1; 循环遍历while (k < 4) {k++};
#如果遍历到单元格级别也不是空背景 if (nextCell.data.number != 0) 遍历结束 k = 4; break;;
#而且如果发现两个单元的级别一样if (cell.data.number == nextCell.data.number)
#级别数据number刷新变化
cell.data.number += 1;
nextCell.data.number = 0;
第二步 填充空数据;
#同理第一步,如果是空背景if (cell.data.number == 0),也是循环遍历while (k < 4) {k++};
#如果遍历到单元格级别不是空背景 if (nextCell.data.number != 0) ,空背景获得该单元格的数据,而该单元格则设为空背景;
cell.data.number = nextCell.data.number;
nextCell.data.number = 0;
- //direction left
- MainLayer.prototype.leftCombineNumber = function () {
- for (var j = 0; j < 4; j++) {
- for (var i = 0; i < 4; i++) {
- var cell = this.tables[i][j];
- if (cell.data.number != 0) {
- var k = i + 1;
- while (k < 4) {
- var nextCell = this.tables[k][j];
- if (nextCell.data.number != 0) {
- if (cell.data.number == nextCell.data.number) {
- cell.data.number += 1;
- nextCell.data.number = 0;
- this.totalScore += SCORES[cell.data.number];
- }
- k = 4;
- break;
- }
- k++;
- }
- }
- }
- }
- for (j = 0; j < 4; j++) {
- for (i = 0; i < 4; i++) {
- cell = this.tables[i][j];
- if (cell.data.number == 0) {
- k = i + 1;
- while (k < 4) {
- nextCell = this.tables[k][j];
- if (nextCell.data.number != 0) {
- cell.data.number = nextCell.data.number;
- nextCell.data.number = 0;

- }

- }
- }

- //direction right
- MainLayer.prototype.rightCombineNumber = function () {

- }
- }
- }
- this.refreshNumber();
- };
- MainLayer.prototype.downCombineNumber = function () {
- for (var i = 0; i < 4; i++) {
- for (var j = 0; j < 4; j++) {
- var cell = this.tables[i][j];
- if (cell.data.number != 0) {

- }
- k = 4;
- break;
- }
- k++;
- }
- }
- }
- }
- for (i = 0; i < 4; i++) {
- for (j = 0; j < 4; j++) {

- cell.data.number = nextCell.data.number;
- nextCell.data.number = 0;
- k = -1;
- }
- k--;
- }
- }
- }
- }
- this.refreshNumber();
- };
3 刷新数据和颜色;
上面的算法完成了,只是该精灵的data里面的数据发生了变化,但视觉上没有任何变化,所以需要刷新数据和颜色
#新建一个空背景数组emptyCellList;
#又是循环二维数组this.tables
#得到单元格的文字标签label,和级别cellNumber
#如果不是空背景cellNumber!=0,label显示和设置文字内容和大小,同时如果检测到是最高级别,游戏成功结束
#如果是空背景,label隐藏 emptyCellList添加该元素emptyCellList.push(cell);;
#得到一个emptyCellList后,如果发现该数组大小为空,也就无法再产生一个数字2了,游戏over;
#而如果数组大小不是空,随机取一个位置randomCell,设置数据等级为0,数字为2,并播放缩放动画runAction;
- MainLayer.prototype.refreshNumber = function () {
- var emptyCellList = [];
- for (var i = 0; i < 4; i++) {
- var numbers = " ";
- for (var j = 0; j < 4; j++) {
- var cell = this.tables[i][j];
- var label = cell.data.numberLabel;
- var cellNumber = cell.data.number;
- if (cellNumber != 0) {
- cell.setColor(COLOR[cellNumber]);
- label.setString(this.indexVersion.array[cellNumber] + " ");
- label.setFontSize(this.indexVersion.labelFontSize);
- label.setVisible(true);
- if (cellNumber == (this.indexVersion.array.length - 1)) {
- //check success
- var toast = cc.Toast.create(this.rootNode, "成功到达:" + this.indexVersion.array[cellNumber], 2);
- toast.setColor(cc.c3b(255, 0, 0));
- this.rootNode.scheduleOnce(function () {
- cc.BuilderReader.runScene("", "MainLayer");
- }, 2)
- }
- } else {
- cell.setColor(COLOR[cellNumber]);
- label.setVisible(false);
- emptyCellList.push(cell);
- }
- numbers += " " + cellNumber;
- }
- cc.log("numbers==" + numbers);
- }
- //score
- this.scoreLabel.setString("分数:" + this.totalScore);
- if (emptyCellList.length < 1) {
- //check fail
- var toast = cc.Toast.create(this.rootNode, "失败!", 2);
- toast.setColor(cc.c3b(255, 0, 0));
- this.rootNode.scheduleOnce(function () {
- cc.BuilderReader.runScene("", "MainLayer");
- }, 2)
- } else {
- //create random cell
- var randomCell = emptyCellList[getRandom(emptyCellList.length)];
- randomCell.data.number = 1;
- randomCell.data.numberLabel.setVisible(true);
- randomCell.data.numberLabel.setString(VERSIONS[this.versionNum].array[1] + "");
- randomCell.data.numberLabel.setFontSize(this.indexVersion.labelFontSize);
- randomCell.setColor(COLOR[1]);
- randomCell.runAction(cc.Sequence.create(cc.ScaleTo.create(0, 0.8), cc.ScaleTo.create(0.5, 1)));
- }
- };
4 触摸检测 两个触摸点this.pEnded this.pBegan 根据x y确定方向,再根据距离确定左右和上下;
- MainLayer.prototype.onTouchesEnded = function (touches, event) {
- this.pEnded = touches[0].getLocation();
- if (this.pBegan) {
- if (this.pEnded.x - this.pBegan.x > 50) {
- this.rightCombineNumber();
- }
- else if (this.pEnded.x - this.pBegan.x < -50) {
- this.leftCombineNumber();
- }
- else if (this.pEnded.y - this.pBegan.y > 50) {
- this.upCombineNumber();
- }
- else if (this.pEnded.y - this.pBegan.y < -50) {
- this.downCombineNumber();
- }
- }
- };
思路很清晰简单,游戏却是简约不简单;
