@Paulo,
There are many ways to achieve this, but if you don’t want to use Storyboard or Director, you can make your own scene management code like this (very basic example):
-- Forward declare functions local doSplash local doMenu -- Define Functions Below doSplash = function() local splashImage = display.newImageRect( ... fill in your own details ) local function switchToMenu() splashImage:removeSelf() doMenu() end timer.performWithDelay( 3000, switchToMenu ) end doMenu = function() -- Write code to make menu here end -- Run the code above doSplash()
