cocos2d-x开发移动游戏的场景切换示例和技术解答

本示例代码展示了如何使用cocos2d-x开发移动游戏中的场景切换功能，以及一些常见的技术解答。

#include "cocos2d.h"

class HelloWorldScene : public cocos2d::Scene
{
public:
    HelloWorldScene();
    ~HelloWorldScene();

    static HelloWorldScene* create();

    virtual bool init();

    void onStartGame(cocos2d::Ref* pSender);
};

HelloWorldScene::HelloWorldScene()
{

}

HelloWorldScene::~HelloWorldScene()
{

}

HelloWorldScene* HelloWorldScene::create()
{
    HelloWorldScene* ret = new HelloWorldScene();
    if (ret && ret->init())
    {
        ret->autorelease();
        return ret;
    }
    else
    {
        delete ret;
        ret = nullptr;
        return nullptr;
    }
}

bool HelloWorldScene::init()
{
    if (!Scene::init())
    {
        return false;
    }

    auto onGameStartItem = MenuItemFont::create("Start Game", CC_CALLBACK_1(HelloWorldScene::onStartGame, this));
    onGameStartItem->setPosition(Vec2(240, 160));
    auto menu = Menu::create(onGameStartItem, nullptr);
    menu->setPosition(Vec2::ZERO);
    this->addChild(menu, 1);

    return true;
}

void HelloWorldScene::onStartGame(Ref* pSender)
{
    // 切换到GameScene场景
    auto scene = GameScene::create();
    Director::getInstance()->replaceScene(scene);
}

class GameScene : public cocos2d::Scene
{
public:
    GameScene();
    ~GameScene();

    static GameScene* create();

    virtual bool init();
};

GameScene::GameScene()
{

}

{

}

GameScene* GameScene::create()
{
    GameScene* ret = new GameScene();
    if (ret && ret->init())
    {
        ret->autorelease();
        return ret;
    }
    else
    {
        delete ret;
        ret = nullptr;
        return nullptr;
    }
}

bool GameScene::init()
{
    if (!Scene::init())
    {
        return false;
    }

    // TODO: 在此处添加游戏逻辑

    return true;
}


// 在main函数中进行场景切换
int main(int argc, char** argv)
{
    // 初始化游戏引擎
    auto director = Director::getInstance();
    auto glview = director->getOpenGLView();
    if (!glview)
    {
        glview = GLViewImpl::create("My Game");
        director->setOpenGLView(glview);
    }

    // 设置设计分辨率和帧率
    glview->setDesignResolutionSize(480, 320, ResolutionPolicy::SHOW_ALL);
    director->setDisplayStats(true);
    director->setAnimationInterval(1.0 / 60);

    // 运行开始场景
    auto scene = HelloWorldScene::create();
    director->runWithScene(scene);

    return director->runMainLoop();
}
