Bonjour à tous,
M’étant lancé depuis quelque semaine dans la création d’un mod rajoutant quelque block à minecraft, j’ai suivi beaucoup de vos tutoriel et je commence à comprendre le truc néanmoins, je suis coincé depuis quelques jour sur les dalles.
Après quelque recherche sur le forum, j’ai trouvé les sources pour la version 1.7.2. Mais dès que je tente de poser une dalle sur une autre (pour faire une double dalle) le jeu crash et j’obtiens cette erreur :
