我想控制一个sp的视点，但是加了self.m_pUILayer = cc.CSLoader:createNode(“csb/LoginLayer.csb”)
self:addChild(self.m_pUILayer)后sp就显示不出来了，请问是为什么啊？
下面是代码：
self.m_pUILayer = cc.CSLoader:createNode(“csb/LoginLayer.csb”)
self:addChild(self.m_pUILayer)
local s = cc.Director:getInstance():getWinSize()
local camControlNode = cc.Node:create()
camControlNode:setNormalizedPosition(cc.p(0.5, 0.5))
self:addChild(camControlNode)
local camNode = cc.Node:create()
camNode:setPositionZ(cc.Camera:getDefaultCamera():getPosition3D().z)
camControlNode:addChild(camNode)
local sp2 = cc.Sprite:create("mofazhen.png")
sp2:setPosition(s.width/2, s.height/2-80)
self:addChild(sp2)
local sp = cc.Sprite:create("mofazhen.png")
sp:setPosition(s.width/2, s.height/2+20)
local ro1 = cc.RotateBy:create(20, 360)
local re = cc.RepeatForever:create(ro1)
sp:runAction(re)
self:addChild(sp)
local _ca = cc.Camera:create()
self:addChild(_ca)
_ca:setCameraFlag(cc.CameraFlag.USER1)
sp:setCameraMask(2)
