在Cocos2d中使用哪个EventDispatcher？节点：： EventDispatcher或导演：： EventDispatcher？

Question

要在cocos2d中使用哪个EventDispatcher？节点：： EventDispatcher或导演：： EventDispatcher？在参考了Director类和Node类的官方文档之后Director Class Reference Cocos2d-xNode Class Reference Cocos2d-x我有点困惑，使用

有什么区别

Director::getInstance()->getEventDispatcher() // consider this is used inside a class which is derived from Node class

或

this->getEventDispatcher() // consider this refers to a class derived from Node class

Answer 1

两者都是一样的。 this-> getEventDispatcher（）调用CCNode的getEventDispatcher（）函数。它返回_eventDispatcher。

_eventDispatcher = _director->getEventDispatcher(); // Check CCNode.cpp

所以这3个相同

Director::getInstance()->getEventDispatcher()

this->getEventDispatcher()

_eventDispatcher->addEventListenerWith..
