- 调度器(scheduler)
@H_190_502@继承关系 @H_190_502@ |
@H_190_502@默认调度器(scheduleUpdate) 该调度器是使用Node的刷新事件update方法,该方法在每帧绘制之前都会被调用一次。由于每帧之间时间间隔较短,所以每帧刷新一次已足够完成大部分游戏过程中需要的逻辑判断。 Cocos2d-x中Node默认是没有启用update事件的,因此你需要重载update方法来执行自己的逻辑代码。 @H_190_502@通过执行schedulerUpdate()调度器每帧执行 update方法,如果需要停止这个调度器,可以使用unschedulerUpdate()方法。 @H_190_502@ @H_190_502@HelloWorldScene.h中添加如下代码: @H_190_502@void update(float dt) override; @H_190_502@ @H_190_502@HelloWorldScene.cpp中的代码如下: @H_190_502@bool HelloWorld::init() @H_190_502@{ @H_190_502@... @H_190_502@scheduleUpdate(); @H_190_502@return true; @H_190_502@} @H_190_502@ @H_190_502@void HelloWorld::update(float dt) @H_190_502@{ @H_190_502@log("update"); @H_190_502@} @H_190_502@ @H_190_502@运行结果: @H_190_502@cocos2d: update @H_190_502@cocos2d: update @H_190_502@cocos2d: update @H_190_502@cocos2d: update |
@H_190_502@自定义调度器: 游戏开发中,在某些情况下我们可能不需要频繁的进行逻辑检测,这样可以提高游戏性能。所以Cocos2d-x还提供了自定义调度器,可以实现以一定的时间间隔连续调用某个函数。 由于引擎的调度机制,自定义时间间隔必须大于两帧的间隔,否则两帧内的多次调用会被合并成一次调用。所以自定义时间间隔应在0.1秒以上。 @H_190_502@同样,取消该调度器可以用unschedule(SEL_SCHEDULE selector,float delay)。 @H_190_502@ @H_190_502@以下代码用来测试该调度器: @H_190_502@HelloWorldScene.h 代码如下: @H_190_502@void updateCustom(float dt); @H_190_502@ @H_190_502@HelloWorldScene.cpp 代码如下: @H_190_502@bool HelloWorld::init() @H_190_502@{ @H_190_502@... @H_190_502@schedule(schedule_selector(HelloWorld::updateCustom),1.0f,kRepeatForever,0); @H_190_502@return true; @H_190_502@} @H_190_502@ @H_190_502@void HelloWorld::updateCustom(float dt) @H_190_502@{ @H_190_502@log("Custom"); @H_190_502@} @H_190_502@ @H_190_502@在控制台你会看到每隔1秒输出一下信息: @H_190_502@cocos2d: Custom @H_190_502@cocos2d: Custom @H_190_502@cocos2d: Custom @H_190_502@cocos2d: Custom @H_190_502@cocos2d: Custom @H_190_502@ @H_190_502@我们来看下scheduler(SEL_SCHEDULE selector,float interval,unsigned int repeat,float delay)函数里面的参数:
|
@H_190_502@1单次调度器(schedulerOnce) @H_190_502@该调度器只会触发一次,用unschedule(SEL_SCHEDULE selector,float delay)来取消该触发器。 @H_190_502@以下代码用来测试调度器: @H_190_502@HelloWorldScene.h 代码如下: @H_190_502@void updateOnce(float dt); @H_190_502@ @H_190_502@HelloWorldScene.cpp代码如下: @H_190_502@bool HelloWorld::init() @H_190_502@{ @H_190_502@... @H_190_502@scheduleOnce(schedule_selector(HelloWorld::updateOnce),0.1f); @H_190_502@return true; @H_190_502@} @H_190_502@ @H_190_502@void HelloWorld::updateOnce(float dt) @H_190_502@{ @H_190_502@log("Once"); @H_190_502@} @H_190_502@在控制台中看到的效果: @H_190_502@cocos2d: Once |

1.Event--------EventTouch,EventCustom,EventMouse,EventKeyboard,EventFocus,EventAcceleration
其中,EventTouch和 EventCustom是比较特殊的两个Event。EventTouch是3.x版本的触摸机制相关的Event,而EventCustom则是3.x自定义事件机制的基础,该机制取代了2.x版本中的NotificationCenter。
2.EventListener-------------EventListenerTouchOneByOne,EventListenerTouchAllAtOnce,EventListenerCustom,EventListenerFocus,EventListenerMouse....对应
相比于Event,Listener多了一个,因为对应的Touch被拆分成了两个Listener,一个是OneByone,一个是TouchAllAtOnce。前者是onTouchBegan等函数的Listener,后者是onTouchesBegan等函数的Listener。
1.2.EventDispatcher,EventListener,Event三者的关系
Event相当于data,EventListener包含了data与fuction的一种映射关系,而EventDispatcher相当于一个Manager,管理着EventListener,决定着Event的调用顺序。
Event中包含了type,target等信息;EventListener包含了ListenerID,相关联的Node,对应的callBack;EventDispatcher里含有各种map,vector来管理不同的Listener。 @H_190_502@*/ |
