别踩白块儿游戏源代码

运行 demo 需要配置好 CocosEditor，暂不支持其他工具。demo 是跨平台的，可移植运行 android，ios，html5 网页等，代码是基于 javascript 语言，cocos2d-x 游戏引擎，CocosEditor 手游开发工具完成的。

代码分析：（只挑选核心主代码分析，更多细节自行研究源码）

1 创建曲谱数组  do、re、mi、fa，sol、la、duo

CITY_OF_SKY = [
    4, 3, 4, 1, 3 , 3, 1, 1, 1, 7, 4, 4, 7, 7, 6, 7,
    1, 7, 1, 3, 7 , 3 , 6, 5, 6, 1 , 5 , 3, 3];

2 初始化表格，本来先创建4*曲谱数组长度的表格，但为了优化，先创建4*5表格，使用时候再不断新建增加表格；

 //tables
    this.tables = new Array(this.pianoLengthIndex);
    for (var j = 0; j < this.pianoLength; j++) {
        var sprites = new Array(4);
        var random = getRandom(4);
        for (var i = 0; i < 4; i++) {
            sprites[i] = this.newBlock(i, j, random);
        }
        this.tables[j] = sprites;
    }

3 创建单个表格元素，可根据colortype在一行里确定一个黑色元素

MainLayer.prototype.newBlock = function (i, j, colorType) {
    //simple block
    var block = cc.Sprite.create("res/whiteBlock.png");
    block.setPosition(cc.p(this.blockWidth / 2 + this.blockWidth * i, this.blockHeight / 2 + this.blockHeight * j));
    block.setScaleX(this.scaleX);
    block.setScaleY(this.scaleY);
    block.setZOrder(100);
    block.setAnchorPoint(cc.p(0.5, 0.5));
    var color = "white";
    if (j == 0) {
        block.setColor(cc.c3b(0, 255, 0));
    } else {
        if (i == colorType) {
            block.setColor(cc.c3b(30, 30, 30));
            color = "black";
        }
    }
    block.blockData = {col: i, row: j, color: color};
    this.blockNode.addChild(block);
    return block;
};

4 触摸表格，如果是黑色；如果是当前一行的上一行才能继续；

#如果没到顶，创建新的一行moveAddNewSprites，如果到顶了，创建分数结束节点createTopOverNode；

#如果整个表格移动到顶if (block.blockData.row == (this.pianoLengthIndex - 1))，游戏结束 this.gameStatus = OVER;

#如果没到顶，整个表格往下移一行this.blockNode.runAction(cc.MoveTo.create(0.2, cc.p(0, (this.blockNode.getPositionY() - this.blockHeight * heightNum))));

#单个元素运行一个缩放动画，移动步数+1； this.moveNum += 1;

//touch black
                        if (block.blockData.color == "black") {
                            if (block.blockData.row == (this.moveNum + 1)) {

                                //create new sprite 
                                if (this.pianoLength < this.pianoLengthIndex) {  //not reach top
                                    this.moveAddNewSprites();
                                }

                                if (this.pianoLength == this.pianoLengthIndex) {  //when reach top
                                    this.createTopOverNode();
                                }

                                //move down
                                cc.AudioEngine.getInstance().playEffect(PIANO_SIMPLE[this.pianoListIndex[j - 1]], false);
                                block.setColor(cc.c3b(100, 100, 100));
                                var heightNum = 1;
                                if (block.blockData.row == (this.pianoLengthIndex - 1)) { //when last row ,game success end, move two height
                                    heightNum = 2;
                                    cc.log("end");
                                    this.gameStatus = OVER;
                                    cc.AudioEngine.getInstance().playEffect(SOUNDS.win, false);

                                }
                                this.blockNode.runAction(cc.MoveTo.create(0.2, cc.p(0, (this.blockNode.getPositionY() - this.blockHeight * heightNum))));
                                this.moveNum += 1;
                                block.runAction(cc.Sequence.create(
                                    cc.ScaleTo.create(0, this.scaleX * 4 / 5, this.scaleY),
                                    cc.ScaleTo.create(0.2, this.scaleX, this.scaleY)
                                ));
                            }
                        }

5 触摸表格，如果是白色，游戏结束；

#创建分数结束节点this.createTopOverNode();

#改变分数节点的颜色背景，结果失败；

                           this.createTopOverNode();   //create score node and move 
                            this.gameStatus = OVER;
                            cc.AudioEngine.getInstance().playEffect(SOUNDS.error, false);
                            block.setColor(cc.c3b(255, 0, 0));
                            block.runAction(cc.Sequence.create(
                                cc.ScaleTo.create(0, this.scaleX * 4 / 5, this.scaleY * 4 / 5),
                                cc.ScaleTo.create(0.2, this.scaleX, this.scaleY)
                            ));
                            this.scoreNode.bgColor.setColor(cc.c3b(255, 0, 0));
                            this.scoreNode.result.setString("失败了");
                            this.scoreNode.runAction(cc.MoveTo.create(0.2, cc.p(0, this.blockHeight * this.moveNum)));

6 创建添加新的一行

MainLayer.prototype.moveAddNewSprites = function () {
    cc.log("moveAddNewSprites");
    var sprites = new Array(4);
    var random = getRandom(4);
    for (var k = 0; k < 4; k++) {
        sprites[k] = this.newBlock(k, this.pianoLength, random);
    }
    this.tables[this.pianoLength] = sprites;
    this.pianoLength += 1;
};

7 分数结束节点创建函数

MainLayer.prototype.createTopOverNode = function () {
    //top score node
    this.scoreNode = cc.Node.create();
    this.scoreNode.setPosition(cc.p(0, this.blockHeight * this.pianoLength));
    this.scoreNode.setAnchorPoint(cc.p(0, 0));
    this.scoreNode.setZOrder(130);
    this.blockNode.addChild(this.scoreNode);

    //color bg
    var bgColor = cc.Sprite.create("res/whiteBlock.png");
    bgColor.setPosition(cc.p(0, 0));
    bgColor.setScaleX(720 / 300);
    bgColor.setScaleY(1280 / 500);
    bgColor.setAnchorPoint(cc.p(0, 0));
    bgColor.setColor(cc.c3b(0, 255, 0));
    this.scoreNode.addChild(bgColor);
    this.scoreNode.bgColor = bgColor;

    //mode
    var wordsMode = ["经典", "街机", "禅"];
    var modeLabel = cc.LabelTTF.create(wordsMode[GAME_MODE] + "模式", "Arial", 70);
    this.scoreNode.addChild(modeLabel);
    modeLabel.setPosition(cc.p(350, 1000));
    modeLabel.setColor(cc.c3b(0, 0, 0));
    modeLabel.setAnchorPoint(cc.p(0.5, 0.5));

    //result
    var resultLabel = cc.LabelTTF.create("成功了", "Arial", 110);
    this.scoreNode.addChild(resultLabel);
    resultLabel.setPosition(cc.p(360, 750));
    resultLabel.setAnchorPoint(cc.p(0.5, 0.5));
    resultLabel.setColor(cc.c3b(139, 58, 58));
    this.scoreNode.result = resultLabel;

    //back
    var backLabel = cc.LabelTTF.create("返回", "Arial", 50);
    this.scoreNode.addChild(backLabel);
    backLabel.setPosition(cc.p(200, 400));
    backLabel.setAnchorPoint(cc.p(0.5, 0.5));
    backLabel.setColor(cc.c3b(0, 0, 0));
    this.scoreNode.back = backLabel;

    //return
    var returnLabel = cc.LabelTTF.create("重来", "Arial", 50);
    this.scoreNode.addChild(returnLabel);
    returnLabel.setPosition(cc.p(500, 400));
    returnLabel.setAnchorPoint(cc.p(0.5, 0.5));
    returnLabel.setColor(cc.c3b(0, 0, 0));
    this.scoreNode.return = returnLabel;
};
