Salve a tutti , sono nuovo e sto cercando di comprendere as3.
Mi serve una gallery che carichi le immagini ed il testo da un file xml, che faccio lo slide ogni tot secondi .
Ho trovato un codice in rete che fa al caso mio, ma vorrei personalizzarlo un po'.
vorrei oltre al timer due pulsanti che appaiano con il mouse sulla foto per andare avanti e indietro nello slideshow. se li metto nello stage appaiono sempre sotto alla foto, anche se su un livello superiore. Forse dovrei chiamarli da codice ma non saprei come fare e tanto meno modificare il codice per mantenere sia il timer che i pulsanti.
Non riesco a formattare con font colore dimensione il testo che carico da xml.
Anche questo testo vorrei farlo comparire solo con il mouse sopra l'immagine.

Se qualcuno riuscisse a darmi in aiuto....grazie.
