cocos2dx中启用lua脚本

AppDelegate 的 applicationDidFinishLaunching 方法中加载Lua引擎

bool AppDelegate::applicationDidFinishLaunching()

    pDirector->setAnimationInterval(1.0 / 60);

    // register lua engine
    CCLuaEngine *pEngine = CCLuaEngine::defaultEngine();
    CCScriptEngineManager::sharedManager()->setScriptEngine(pEngine);

    CCLuaStack *pStack = pEngine->getLuaStack();

    // load framework

        pStack->loadChunksFromZip(precompiledFrameworkPath.c_str());
    }

    // load script
    string path = CCFileUtils::sharedFileUtils()->fullPathForFilename(m_projectConfig.getScriptFileRealPath().c_str());
