Salut, je travaille sur mon patfinthing depuis un moment est sa veut toujours pas marcher 
svp i need your help ^^'
voici mon code (c'est un a*)
et la class node
Help me T_T en analisant jai remarquer que la liste ouverte etait vide ce qui provoquait la fin de l'éxécutions
svp i need your help ^^'voici mon code (c'est un a*)
Code:
