J'ai récemment décidé d'apprendre et de faire de petits jeux 2D en utilisant le framework XNA. J'ai donc commencé par éditer un exemple dans le livre "XNA 4.0 Game Development by Example" par Kurt Jaegers et atm je suis bloqué à l'affichage des sprites .. Je voudrais faire quelque chose comme mahjong solitaire où les tuiles sont détruites quand vous sélectionnez deux mêmes pièces. Donc, je suis en train d'afficher un tableau avec des morceaux aléatoires, mais je ne sais pas comment dessiner des carreaux cliqués dans des couleurs différentes pour montrer que je l'ai sélectionné. C'est la classe principale Game1:Tuiles Clickable
