Instance Name

the syntax is {{parent}}.{{name}}. You can access it like

• local obj = UI.sceneGroup(“three.eight”)

  A parent.name should be unique in all the layers in a page

  Application.lua

  function newModule(name)
    local M = {}
    local parent = name:match("(.-)[^%.]+$")
    local root = parent:sub(1, parent:len()-1):match("(.-)[^%.]+$")
    M.name = name:sub(root:len()+1)
    local isLayers = M.name:find("layers.")
    if isLayers then
      M.name = M.name:sub(8)
    end
    M.newInstance = newInstance
    return parent, root, M
  end
  

  for example, let’s make an instance of layer group - three

  

       layers = {
        {one = {}},
        {two={class={"linear"}}},
        {three = {
          { four={}},
          { five={class={"myClass"}}},
          { six={
              { seven = {class={"myClass", "linear"}}},
              { eight = {}}
            }
          }
        }}
      },
  

  

  You can import it to another page like this

  layers = {
     {  bg={} },
     {  three={ class={"imported", "linear"} } },
   },
