Il mio piccolo gioco prevede che si ripeta per alcune scene
cambiando solo l’aspetto grafico,
allora ho utilizzato Multiscene Applicatione.
Ho letto il tutorial sulle Storyboard
è ho cercato di dividere il mio gioco nelle parti giuste

ma mi da errore alla global createsmile(),
dove sbaglio?
Per “pulire” tutto e alleggerire la memoria cosa va
nella function scene:destroy( event )?
ancora grazie per l’aiuto
