cocoseditor-piano别踩白块儿游戏
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;
};
