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; 
这里随机设置颜色，使用了C++中的随机数。接下来
labelWelcome0->setColor(c0); 
labelWelcome1->setColor(c1); 
labelWelcome2->setColor(c2); 
labelWelcome3->setColor(c3);

char* 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;
}

现在可以将中间的文字显示出来了：
CLabelTTF *labelWelcome4=CCLabelTTF::create(G2U("游戏开发的世界，我用Cocos2d-x来降服你了~！"),"Verdana",35);
