今天逛cocos论坛的时候 发现有这样一个接口
findChildren
还有一个findChild没有在3.10或者自己的项目中找到使用 应该是与getChildByName用法一样
findChildren查了半天用途
他可以获得所有同一名称的子节点
看示例
--复制24个节点 设置得到的坐标 并添加到容器层里面 这个容器层作为可克隆的节点
function PXUISkill:initPageItem()
local function addItemToPanel(i)
local item = self.m_Image_DownItem:clone()
--item:show()
item:setTag(i)
local tbPoint = self.tbPanelSPos[i]
item:setPosition(tbPoint.x, tbPoint.y)
self.m_Panel_SkillPvItem:addChild(item)
end
for i = 1, Msd.DOWN_SKI_NUM do
addItemToPanel(i)
end
--得到全部的克隆节点
local findChildren = cc.utils:findChildren(self.m_Panel_SkillPvItem, "m_Image_DownItem")
dump(findChildren, "findChildren = ")
local a = self.m_Panel_SkillPvItem:getChildByName("m_Image_DownItem")
dump(a, "a = ")
end
输出

可见
cc.utils:findChildren可获得全部子节点
也可以#结果 得到有多少个这个名字的节点
