2.Node 里面的事件

成员变量

#if CC_ENABLE_SCRIPT_BINDING
    int _scriptHandler;               ///< script handler for onEnter() & onExit(), used in Javascript binding and Lua binding.
    int _updateScriptHandler;         ///< script handler for update() callback per frame, which is invoked from lua & javascript.
    ccScriptType _scriptType;         ///< type of script binding, lua or javascript
#endif


// override me
void Node::update(float fDelta)
{
#if CC_ENABLE_SCRIPT_BINDING
    if (0 != _updateScriptHandler)
    {//派发事件消息到lua
        //only lua use
        SchedulerScriptData data(_updateScriptHandler,fDelta);
        ScriptEvent event(kScheduleEvent,&data);
        ScriptEngineManager::getInstance()->getScriptEngine()->sendEvent(&event);
    }
#endif
    
    if (_componentContainer && !_componentContainer->isEmpty())
    {
        _componentContainer->visit(fDelta);
    }
}

其他还有很多派发手段，大体思路就是通过ScriptEngine 来派发事件，因为大部分C++类 都通过toLua导出到lua的，导出类自动把lua的handle通过接口ScriptHandlerMgr::getInstance()->addObjectHandler绑定到cpp对象，然后就能相互调用
