Time for action – adding the loading screen

We'll place loading screens when the application launches and before the game level starts. This tells the user that more content or information is on its way.

1. Create a new file called loadmainmenu.lua in your project folder.

2. Import Composer and add in the composer.newScene() function:

   local composer = require( "composer" )
   local scene = composer.newScene()

3. Create two local variables called myTimer and loadingImage. Add in the create() event and a sceneGroup display group:

   local myTimer
   local loadingImage
   
   -- Called when the scene's view does not exist:
   function scene:create( event )
     local sceneGroup = self.view
   
     print( "\nloadmainmenu: create event" )
   end

4. Create the show() event and add in a sceneGroup display group:

     -- Called immediately after scene has moved onscreen:
   function scene:show( event )
     local sceneGroup = self.view
   
     print( "loadmainmenu: show event" )

5. Introduce the loadingImage display object:

     loadingImage = display.newImageRect...
