Jeu du demineur en JAVA
Voici un exemple de code source du jeu du démineur fait en JAVA. Peu de ligne de code, un jeu vraiment bien fait, Bravo SciWizEH !!!La class comporte peu de commentaire, analysons les grandes lignes du jeu MineSweep:
1. chaque case est un objet de type JButton auquel on ajoute l’événement Action et Mouse au moyen d'un listener,
2. la fonction doCheck() comporte l'algo a proprement dit. A chaque coup joué, la class détermine si le joueur a gagné, a perdu et s'il peut continuer a jouer.

Notez bien que je ne suis pas l'auteur du jeu, la class a été trouvé sur le net. Le jeu du démineur en java est partagé sur Fobec.com car il est intéressant d'avoir un exemple de comment programmer en jeu avec JAVA.
