触摸事件

键盘响应事件

auto mKeyboardListener = EventListenerKeyboard::create();  //键盘响应事件//键盘按下事件监听mKeyboardListener->onKeyPressed = [](EventKeyboard::KeyCode keyCode, Event* event){	log("keyCode=%d", keyCode);};//键盘释放事件监听mKeyboardListener->onKeyReleased = [](EventKeyboard::KeyCode keyCode, Event* event){	log("keyCode=%d", keyCode);if (EventKeyboard::KeyCode::KEY_ESCAPE == keyCode){#if (CC_TARGET_PLATFORM == CC_PLATFORM_WP8) || (CC_TARGET_PLATFORM == CC_PLATFORM_WINRT)	MessageBox("You pressed the close button. Windows Store Apps do not implement a close button.", "Alert");	return;#endif	Director::getInstance()->end();#if (CC_TARGET_PLATFORM == CC_PLATFORM_IOS)	exit(0);#endif	}};_eventDispatcher->addEventListenerWithSceneGraphPriority(mKeyboardListener, this);  //将键盘响应事件交给分发器来管理

鼠标响应事件

auto _mouseListener = EventListenerMouse::create();// 事件响应逻辑_mouseListener->onMouseMove = [=](Event *event){	EventMouse* e = (EventMouse*)event;	log("Key=%d", e->getMouseButton());};_mouseListener->onMouseUp = [=](Event *event){};_mouseListener->onMouseDown = [=](Event *event){};_mouseListener->onMouseScroll = [=](Event *event){};// 加入�到事件分发器_eventDispatcher->addEventListenerWithSceneGraphPriority(_mouseListener, this);

自己定义事件

auto mCustomListener = EventListenerCustom::create("my_custom_l", [](EventCustom* event){char* c = static_cast
      
       (event->getUserData());log("%s", c);});/*将自自己定义事件交给分发器来管理，这样的方式是使用优先级别来设置SceneGraphPriority和FixedPriority差别在于前者是在析构函数中会被移除后者是须要手动移除*/_eventDispatcher->addEventListenerWithFixedPriority(mCustomListener, 1);EventCustom _event("my_custom_l");//char* cstr = "this is my custom listener!";static int count = 0;++count;char* buf;sprintf(buf, "this is my custom %d", count);_event.setUserData(buf);_eventDispatcher->dispatchEvent(&_event);  //手动触发自己定义事件
      

加速计事件
