[cocos2d-x]HelloWorldDemo(Mac&Win7两个版本)

实现一个demo，具备以下功能：

1.让几个字分别位于中间和四个角落。

2.中间的字体改变，并且带有闪烁功能。

3.单点触摸和多点触摸，并且能够实现滑动效果，滑动的话必须使用带有bool返回值的单点触摸设置为true。

4.下面两个按钮能够实现添加节点和移除节点的作用。

搞了一段时间的unity3d，最近又重温一下cocos2dx，由于没有mac机，就只能用windows来配置开发环境，依旧从HelloWorld开始！

配置环境：我用的是VS2012，python2.7.3貌似，安装完毕后设置一下环境变量，添加上C:\Python27，然后cocos2dx2.4.2版本，然后cmd创建新工程。

然后在project文件夹下就能看到新建的工程了！

效果图：

上面红色的字我已经标注的很清楚，新手第一次碰到的时候都会想，我要输入中文，但显示出来确实乱码，这就是编码问题，只要转码就OK了！

代码：

                CCLabelTTF *labelWelcome0=CCLabelTTF::create("Hello","微软雅黑",48);CCLabelTTF *labelWelcome1=CCLabelTTF::create("World","宋体",48);CCLabelTTF *labelWelcome2=CCLabelTTF::create("Welcome","Consolas",48);CCLabelTTF *labelWelcome3=CCLabelTTF::create("DingXiaowei","Bitstream Vera Sans Mono",48);CCSize size = CCDirector::sharedDirector()->getWinSize();float width = size.width;float height = size.height;CCSize s0 = labelWelcome0->getContentSize();CCSize s1 = labelWelcome1->getContentSize();CCSize s2 = labelWelcome2->getContentSize();CCSize s3 = labelWelcome3->getContentSize();labelWelcome0->setPosition(CCPointMake(s0.width/2,size.height-s0.height/2));labelWelcome1->setPosition(ccp(size.width-s1.width/2,size.height-s1.height/2));labelWelcome2->setPosition(CCPoint(s2.width/2,s2.height/2));labelWelcome3->setPosition(ccp(size.width-s3.width/2,s3.height/2));addChild(labelWelcome0,1);addChild(labelWelcome1,1);addChild(labelWelcome2,1);addChild(labelWelcome3,1);CCLabelTTF * namelabel =  CCLabelTTF::create(G2U("Cocos2d-x,我爱你！"),"微软雅黑",48);namelabel->setPosition(ccp(size.width/2,size.height/2));addChild(namelabel,1);

转码的方法：

//转码成utf-8,windows默认gb2312char* HelloWorld::G2U(const char* gb2312)  {  int len = MultiByteToWideChar(CP_ACP, 0, gb2312, -1, NULL, 0);  wchar_t* wstr = new wchar_t[len+1];  memset(wstr, 0, len+1);  MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wstr, len);  len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL);  char* str = new char[len+1];  memset(str, 0, len+1);  WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL);  if(wstr) delete[] wstr;  return str;  }

设置字体颜色：

//设置颜色，其实是一个rgb三原色，0-255的三种组合srand((unsigned) time(NULL));ccColor3B c0,c1,c2,c3,c4;c0.r=rand()%256;c0.g=rand()%256;c0.b=rand()%256;c1.r=rand()%256;c1.g=rand()%256;c1.b=rand()%256;c2.r=rand()%256;c2.g=rand()%256;c2.b=rand()%256;c3.r=rand()%256;c3.g=rand()%256;c3.b=rand()%256;c4.r=rand()%256;c4.g=rand()%256;c4.b=rand()%256;labelWelcome0->setColor(c0);labelWelcome1->setColor(c1);labelWelcome2->setColor(c2);labelWelcome3->setColor(c3);
