cocos2d-x v3.x Lua 中 [cc.Layer] 如何不让触摸事件向下转递
--比倍界面层local BiBeiLayer = class("BiBeiLayer", function ()
return cc.LayerColor:create(cc.c4b(0,0,0,125))
end)
--初始化
function BiBeiLayer:ctor()
-- 创建一个事件监听器类型为 OneByOne 的单点触摸
locallistenner = cc.EventListenerTouchOneByOne:create()
-- ture 吞并触摸事件,不向下级传递事件;
-- fasle 不会吞并触摸事件,会向下级传递事件;
-- 设置是否吞没事件，在 onTouchBegan 方法返回 true 时吞没
listenner:setSwallowTouches(true)
-- 实现 onTouchBegan 事件回调函数
listenner:registerScriptHandler(function(touch, event)
local location = touch:getLocation()
print("EVENT_TOUCH_BEGAN")
return true
end, cc.Handler.EVENT_TOUCH_BEGAN )
-- 实现 onTouchMoved 事件回调函数
listenner:registerScriptHandler(function(touch, event)
local locationInNodeX = self:convertToNodeSpace(touch:getLocation()).x
print("EVENT_TOUCH_MOVED")
end, cc.Handler.EVENT_TOUCH_MOVED )
-- 实现 onTouchEnded 事件回调函数
listenner:registerScriptHandler(function(touch, event)
local locationInNodeX = self:convertToNodeSpace(touch:getLocation()).x
print("EVENT_TOUCH_ENDED")
end, cc.Handler.EVENT_TOUCH_ENDED )
local eventDispatcher = self:getEventDispatcher()
-- 添加监听器
eventDispatcher:addEventListenerWithSceneGraphPriority(listenner, self)
end
