J'ai ce code diaporama AS3, qui charge un fichier XML avec une liste d'images. Qu'est-ce que je cherche, est un moyen d'ignorer la partie XML, et il suffit de charger toutes les images dans le dossier "images"?Charger les images du dossier dans le diaporama
Comment puis-je ajouter un booléen constant qui décide s'il doit lire les images au hasard ou non? const RANDOM: booléen = true; ...

Comment puis-je l'obtenir pour lire des images aléatoires? –
Créez un tableau avec les index et mélangez-le. –
Comment ferais-je cela? Je suis un noob. –
