主场景

      local MainScene = class("MainScene", function()
          return display.newScene("MainScene")
      end)
      local scheduler = require(cc.PACKAGE_NAME .. ".scheduler")
      function MainScene:onInterval()
          local callback2 = cc.CallFunc:create(function()
              print("replaceScene")
              nextScene = require("app.scenes.LoginScene").new()
              print(nextScene)
              local transition = display.wrapSceneWithTransition(nextScene, "fade", 1.5)
                  --替换,释放mainscence
               display.replaceScene(transition)
          end)
          local fadeOut =cc.FadeOut:create(1.5)
          local action2 = cc.Sequence:create(fadeOut,callback2)
          self.backgroundLayer:runAction(action2)
      end
      function MainScene:ctor()
           self.backgroundLayer = display.newLayer()
           self.backgroundLayer:addTo(self)
           self.backgroundLayer:setCascadeOpacityEnabled(true)
          local callback = cc.CallFunc:create(function()
              print("callback")
              print(self.bg)
              local function callback()
                  self:onInterval()
              end
              scheduler.performWithDelayGlobal(callback, 1)
          end)
          local fadeIn =cc.FadeIn:create(2)
          local action = cc.Sequence:create(fadeIn,callback)
          --background
          self.bg = display.newSprite("Bg/MainBg.png")
              --设置透明度
              :setOpacity(0)
              :center()
              :addTo(self.backgroundLayer)
          self.bg:runAction(action)
          self.author = display.newTTFLabel({text ="onley test",color = cc.c3b(255, 0, 0),size = 64})
              :align(display.CENTER, display.cx,20)
          self.author:addTo(self.backgroundLayer)
      end
      function MainScene:onEnter()
      end
      function MainScene:onExit()
              print("exit")
      end
      return MainScene
  
 

登录场景

      local LoginScene = class("LoginScene", function()
          return display.newScene("LoginScene")
      end)
      function LoginScene:ctor()
      end
