cocos2d-x lua 触摸事件

version: cocos2d-x 3.6

1.监听

function GameLayer:onEnter()    local eventDispatcher = self:getEventDispatcher()    local function onTouchBegan(touch, event)        local locationInNode = self:convertToNodeSpace(touch:getLocation())        local s = self:getContentSize()        local rect = cc.rect(0, 0, s.width, s.height)        if cc.rectContainsPoint(rect, locationInNode) then            self:setColor(cc.c3b(255, 0, 0))            return true        end        return false        end    local function onTouchMoved(touch, event)    end    local  function onTouchEnded(touch, event)        self:setColor(cc.c3b(255, 255, 255))    end    local listener = cc.EventListenerTouchOneByOne:create()    self._listener = listener    listener:setSwallowTouches(true)    listener:registerScriptHandler(onTouchBegan,cc.Handler.EVENT_TOUCH_BEGAN )    listener:registerScriptHandler(onTouchMoved,cc.Handler.EVENT_TOUCH_MOVED )    listener:registerScriptHandler(onTouchEnded,cc.Handler.EVENT_TOUCH_ENDED )    if 0 == self._fixedPriority then        eventDispatcher:addEventListenerWithSceneGraphPriority(listener, self)    else        eventDispatcher:addEventListenerWithFixedPriority(listener,self._fixedPriority)    endend

2.移除

function TouchableSpriteWithFixedPriority:onExit()    local eventDispatcher = self:getEventDispatcher()    eventDispatcher:removeEventListener(self._listener)end

---

3.注意

onEnter和onExit在lua中不会因节点别add和remove而直接被调用，当子节点被父节点add和remove时，会发送enter和exit的消息，所以需要再初始化节点的时候，监听消息，并在收到消息后调用onEnter或onExit。
