首先，作为一个完整的游戏项目，要有满足游戏要求的界面，并实现之间的跳转，不能只有一个游戏主界面。
下面以主场景界面为例：
.h文件
#include "cocos2d.h"
USING_NS_CC;
class menuScene:public Layer{
public:
static Scene * createScene(); //创建场景
CREATE_FUNC(menuScene);
bool init();
void menuCallBack(Ref * obj); //按钮回调函数
};
.CCP文件
#include "menuScene.h"
#include "gameScene.h" //---引用要跳转的的场景
#include "helpScene.h"
#include "aboutScene.h"
Scene * menuScene::createScene(){
auto scene=Scene::create();
scene->addChild(menuScene::create());
return scene;
}
bool menuScene::init(){
if (!Layer::init()) {
return false;
}
//-------添加背景图
auto sp=Sprite::create("img_bg_logo.jpg");
this->addChild(sp);
sp->setPosition(Director::getInstance()->getWinSize().width/2,
Director::getInstance()->getWinSize().height/2 );
auto splogo=Sprite::create("logo.png");
this->addChild(splogo);
splogo->setPosition(Director::getInstance()->getWinSize().width/2,-200);
splogo->runAction(MoveTo::create(1,Vec2(Director::getInstance()->getWinSize(). width/2,Director::getInstance()->getWinSize().height/2)));
splogo->runAction(MoveTo::create(60,Vec2(splogo->getPositionX(),splogo->getPositionY())));
//-------添加按钮
MenuItemFont * itemstart=MenuItemFont::create("开始游戏",
CC_CALLBACK_1(menuScene::menuCallBack,this)); // 添加按钮，和回调函数
itemstart->setPositionY(-100); //设置位置
itemstart->setColor(Color3B(0,255,0));//设置颜色
itemstart->setTag(11); //设置编号
MenuItemFont * itemhelp=MenuItemFont::create("游戏帮助",this));
itemhelp->setPositionY(-150);
itemhelp->setColor(Color3B(0,0));
itemhelp->setTag(12);
MenuItemFont * itemabout=MenuItemFont::create("关于",this));
itemabout->setPositionY(-200);
itemabout->setColor(Color3B(0,0));
itemabout->setTag(13);
Menu * menu=Menu::create(itemstart,itemhelp,itemabout,NULL);
this->addChild(menu);
//-----按钮点击回调函数
switch (((MenuItemFont*)obj)->getTag()) { //强制转换，获取按钮编号
case 11:
{
auto f=gameScene::createScene(); //创建场景
Director::getInstance()->replaceScene(f);//使用导演函数实现跳转
}
break;
case 12:
{
auto f=helpScene::createScene();
Director::getInstance()->replaceScene(f);
}
break;
case 13:
{
auto f=aboutScene::createScene();
Director::getInstance()->replaceScene(f);
}
break;
default:
break;
}
}
