Lanceur UO

Messages : 102 Date d'inscription : 02/09/2008 Localisation : Belgium

Voici le projet :

- Un lanceur qui permettra de télécharger tous les fichiers nécessaires à l'utilisation de UO, de directement avoir les bons fichier (dernières versions) ainsi que les fichiers du serveurs (gumps, muls, maps, login.cfg, ...).
- Le joueur évite ainsi de faire des mauvaises mises à jours en lancant le patcher d'UO (due au version pas encore décrypter).
- Le joueur lance toujours le jeux via le lanceur, du coup si mise à jour il y a des gumps/muls/maps ou autre, elle sera automatiquement téléchargée.
- Gestion d'un pannel de news dans le lanceur pour avoir les dernières MAJ du serveur.

Concrètement la fonction de gestion des versions de fichiers est faite, il reste à gérer les différentes clés registres créées lors de l'installation d'UO, ainsi que le panel de news et je vous mettrais le code source.

Si vous avez des questions n'hésitez pas.

Lanceur UO Launcher2

Voici déjà la première mouture, elle n'est pas propre, il me faut encore organiser le code, le commenter, mais j'ai fait tout ça rapidement l'autre soir puis j'ai juste rajouter les fonctions d'extractions d'archives 7zip (avec la librairie sevenZip que l'on peut trouver sur le net), ainsi que la méthode pour calculer la somme MD5 d'un fichier.

Je nettoierais tout ça plus tard et continuerais le développement car il reste beaucoup à faire.

PS : Je ne joint pas les fichiers d'interface ni de ressources pour l'instant, je ferais une grosse archive avec tout ça à la sortie de la version 1 qui sera opérationnelle.
PPS : Si vous voulez quand même déjà l'interface GUI, faites moi signe et je la posterai ici avant la monture finale.
PPPS : N'hésitez pas à apporter vos suggestions/corrections/commentaires/idée/... ça fait toujours plaisir Smile

Je n'ai pas beaucoup eu le temps d'avancer, j'ai cependant nettoyer une bonne partie du code mal propre, j'utilise désormais le téléchargement asynchrone plutôt que d'utiliser un thread pour ça, et j'ai séparer quelques méthodes dans la classe statique Tools. Bref il reste du boulot et j'essayerais de finir ça pour Nowel si j'en ai le temps :
