    these is no API currently for switching between Scene roSgNodes.
    so as practical advice, work under the same roSgScreen and Scene, instead say use Group nodes as a "para-scenes": attach all elements for a given visual screen (aka design scene) under a single Group node, then attach that to the Scene. When need to change to a new screen, detach (or hide) that group, replace it with another. Functionally this will work the same as if the "master scene" was replaceable

      Hi community I'm making an Roku app and I need to create window instance for can surf between it. The develop is inside the main fuction because is the only way that it works.

      Also I need to create some moduls that it not depend of the main, I have been investigating and is nesessary the nodes use and task.

      This's my code I wonder if you have some example using nodes and task

       

      function ApiConnection()

      m.nodo = createObject("roSGNode", "ContentReader")
      m.nodo.observeField("content", "ApiConnectionLogin")
      m.nodo.control = "RUN"

      end function

       

      sub ApiConnectionLogin()


      data ={
      username:m.txtuser.text,
      password:m.txtPassword.text
      }

       

      body = FormatJSON(data)
      port = CreateObject("roMessagePort")
      request = CreateObject("roUrlTransfer")
      request.SetMessagePort(port)
      request.SetCertificatesFile("common:/certs/ca-bundle.crt")
      request.RetainBodyOnError(true)
      request.AddHeader("Content-Type", "application/json")
      request.SetRequest("POST")
      request.SetUrl("https://www.example.com")
      requestSent = request.AsyncPostFromString(body)

      if (requestSent)
      msg = wait(0, port)
      if (type(msg) = "roUrlEvent")
      body = msg.GetString()
      print body

      m.view = createObject("roSGNode", "ContentReader")
      m.view.observeField("content", "ShowGridScreen")
      m.view.control = "RUN"

      end if
      end if

      end sub

       

      sub ShowGridScreen()


      screen = CreateObject("roSGScreen")
      port = CreateObject("roMessagePort")
      screen.setMessagePort(port)
      scene = screen.CreateScene("playerscreen")
      screen.show()

      end sub
