end

loginpage2.lua

local loginObj = require("com.classess.loginpage1")

Solution

  • Make your custom class like this

    ------------Your class LoadShift---------------
    local LoadShift = {}
    .
    .
    function LoadShift:LoadShiftFunc()
        --do somthing
    end
    .
    .
    return LoadShift
-------------------------------------

    then require it and call that function like

    ---------------------

local LoadShift= require "LoadShift"
LoadShift:LoadShiftFunc()
