Bonjour a tous j’ai un problème au niveau de la gestion de mon snake (son déplacement); Le serpent en grandissant insère les élements tjrs en diagonale ce qui selon moi n’est pas Normale: Ci dessous Le Code Complet: Merci de bien vouloir me suggérer une autre façon de voir le problème si nécessaire . J’accepte tout critique !
