@robin4002 j’ai logiquement fait les modificication mais le jeu crash depuis je ne comprend pas pourquoi ?

Tu essaies d’accéder a une valeur d’un tag NBT null.
Avant chaque utilisation de stack.getTagCompound() il faut que tu t’assures que le tag n’est pas null, en vérifiant avecstack.hasTagCompound() -
@robin4002 Merci beaucoup , c’était la première fois que j’utilisais les nbt tag et je suis encore pas très bon en dev en java.
-
De rien ! Le problème est résolu ?
-
@robin4002 enfaite je viens de remarquer un autre problème , c’est que ça enregistre les nbt tag sur l’item qui se trouve dans l’inventaire , le plus à gauche

Étrange, je ne vois pas ce qui peut expliquer ce comportement
-
@robin4002 j’ai finalement réussi en utilisant la fonction :
findammo(mc.player.inventory.getCurrentItem());
-
@robin4002 Enfaite je viens de regarder j’ai rien changer à mon code , mais le problème c’est que je ne sais pas pourquoi mais quand je relance le monde il y a 1 arme qui est rechargé a 1/6 et les autres à 0/6 à chaque fois que je reviens dans le monde e je ne sais pas d’ou ça viens

@robin4002 tu en penses quoi robin ?

Je ne sais pas

@robin4002 car j’ai essayé de voir de regarder mais a chaque fois ça se remet à 0 mais je ne comprend pas pourquoi
