本文主要是介绍flappy bird游戏源代码揭秘和下载,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
背景:
最近火爆全球的游戏flappy bird让笔者叹为观止,于是花了一天的时间山寨了一个一模一样的游戏,现在把游戏的思路和源码分享出来,代码是基于javascript语言,cocos2d-x游戏引擎,cocos2d-x editor手游开发工具完成的,请读者轻砸;
ps:运行demo必须配置好cocos2d-x editor,暂不支持其他工具。还有demo是跨平台的,可移植运行android,ios,html5移动系统等;
Android Apk下载:(演示效果)
暂时只移植打包到android系统,可下载运行看看效果;

开发工具:
cocos2dx editor,它是开发跨平台的手机游戏工具,运行window/mac系统上,javascript脚本语言,基于cocos2d-x跨平台游戏引擎, 集合代码编辑,场景设计,动画制作,字体设计,还有粒子,物理系统,地图等等的,而且调试方便,和实时模拟;

2 代码编写MainLayer.js
首先,小鸟在向前飞,其实是底部的路和水管在向左移动,相对的你就感觉小鸟在向右飞了;路循环移动代码:
- MainLayer.prototype.groundRun = function ()
- {
- var action1 = cc.MoveTo.create(0.5, cc.p(-120, 0));
- var action2 = cc.MoveTo.create(0, cc.p(0, 0));
- var action = cc.Sequence.create(action1, action2);
- this.ground.runAction(cc.RepeatForever.create(action));
- }
初始化高低不同的水管,每一关卡都由上下两水管和空隙组成。总长度相同,空隙也一定,随机取下面水管的长度,就形成错落有致的水管关卡;
- MainLayer.prototype.newHose = function (num)
- {
- var hoseHeight = 830;
- var acrossHeight = 300;
- var downHeight = 100 + getRandom(400);
- var upHeight = 1100 - downHeight - acrossHeight;
- var hoseX = 400 * num;
- var HoseName = FP_MAIN_TEXTURE.HOSE;
- var ccSpriteDown = cc.Sprite.createWithSpriteFrameName(HoseName[0]);
- ccSpriteDown.setZOrder(1);
- ccSpriteDown.setAnchorPoint(cc.p(0, 0));
- ccSpriteDown.setPosition(cc.p(hoseX, 0));
- ccSpriteDown.setScaleY(downHeight / hoseHeight);
- var ccSpriteUp = cc.Sprite.createWithSpriteFrameName(HoseName[1]);
- ccSpriteUp.setZOrder(1);
- ccSpriteUp.setAnchorPoint(cc.p(0, 0));
- ccSpriteUp.setPosition(cc.p(hoseX, downHeight + acrossHeight));
- ccSpriteUp.setScaleY(upHeight / hoseHeight);
- this.hoseNode.addChild(ccSpriteDown);
- this.hoseNode.addChild(ccSpriteUp);
- this.hoseSpriteList.push(ccSpriteDown);
- this.hoseSpriteList.push(ccSpriteUp);
- return null;
- }
一开始进入游戏让底部路不断移动,初始化水管,显示准备游戏场景;
- MainLayer.prototype.onEnter = function ()
- {
- cc.AnimationCache.getInstance().addAnimations("Resources/flappy_frame.plist");
- this.groundRun();
- this.ground.setZOrder(10);
- this.birdReadyAction();
- this.bird.setZOrder(20);
- this.readyNode.setVisible(true);
- this.overNode.setVisible(false);
- for (var i = 0; i < 30; i++) {
- this.newHose(i);
- }
- }
点击屏幕,小鸟向上飞60dp,然后更快的速度下落(移动动画),同时闪动翅膀(帧动画);
- MainLayer.prototype.birdRiseAction = function ()
- {
- var riseHeight = 60;
- var birdX = this.bird.getPositionX();
- var birdY = this.bird.getPositionY();
- var time = birdY / 600;
- var actionFrame = cc.Animate.create(cc.AnimationCache.getInstance().getAnimation("fly"));
- var flyAction = cc.Repeat.create(actionFrame, 90000);
- var riseAction1 = cc.MoveTo.create(0.2, cc.p(birdX, birdY + riseHeight));
- var riseAction2 = cc.RotateTo.create(0, -30);
- var riseAction = cc.Spawn.create(riseAction1, riseAction2);
- var fallAction1 = cc.MoveTo.create(time, cc.p(birdX, 50));
- var fallAction2 = cc.Sequence.create(cc.DelayTime.create(time / 6), cc.RotateTo.create(0, 30));
- var fallAction = cc.Spawn.create(fallAction1, fallAction2);
- this.bird.stopAllActions();
- this.bird.runAction(cc.Spawn.create(
- cc.Sequence.create(riseAction, cc.DelayTime.create(0.1), fallAction),
- flyAction)
- );
- }
检测碰撞,如果小鸟碰到地面和水管,发生碰撞,这里碰撞直接用cocos2d-x 里面的图片和图片交叉函数 cc.rectIntersectsRect;
- MainLayer.prototype.checkCollision = function ()
- {
- if (this.bird.getPositionY() < 60) {
- cc.log("floor");
- this.birdFallAction();
- return;
- }
- for (var i = 0; i < this.hoseSpriteList.length; i++) {
- var hose = this.hoseSpriteList[i];
- if (!this.isInScreen(hose)) {
- // continue;
- }
- if (cc.rectIntersectsRect(hose.getBoundingBox(), this.bird.getBoundingBox())) {
- cc.log("hose positionX==" + hose.getBoundingBox().x);
- cc.log("this.bird positionX==" + this.bird.getBoundingBox().x);
- cc.log("i==" + i);
- cc.log("birdFallAction");
- this.birdFallAction();
- return;
- }
- }
- }
碰撞后,小鸟先下落,游戏结束场景显示;
- MainLayer.prototype.birdFallAction = function ()
- {
- this.gameMode = OVER;
- this.bird.stopAllActions();
- this.ground.stopAllActions();
- var birdX = this.bird.getPositionX();
- var birdY = this.bird.getPositionY();
- var time = birdY / 2000;
- this.bird.runAction(cc.Sequence.create(
- cc.DelayTime.create(0.1),
- cc.Spawn.create(cc.RotateTo.create(time, 90), cc.MoveTo.create(time, cc.p(birdX, 50))))
- );
- this.overNode.setVisible(true);
- }
游戏的难度主要在于多个水管的移动,小鸟触摸动画,检测碰撞,我把Mainlayer.js所有代码贴出来;
- FP_MAIN_TEXTURE = {
- FRAME_ANIMS: "beanstalk/Resources/bs_main_anims.plist",
