Erreur lors du cassage de blocs
-
Dans ce cas le NPE est sur la ligne :
if(entityPlayer.inventory.hasItem(IceNFire.wandExtendCapture) || entityPlayer.inventory.hasItem(IceNFire.wandOfCapture))
Maintenant faut trouver quel objet est null.
Modifies ton code comme ça :if(entityPlayer. inventory. hasItem(IceNFire. wandExtendCapture) || entityPlayer. inventory. hasItem(IceNFire. wandOfCapture))Et dit moi sur quelle ligne exactement il y a le NPE avec cette modification.

essaye de faire drops.clear() au lieu du remove j ai eu des NPE aussi avec cette methode

Voici mon nouveau code:

Le code ne correspond pas : ligne 28 tu n’as aucune référence à un objet, même si entityPlayer est null, le problème serai à la ligne 29.
Renvoi la fonction entière et le crash report correspondant.

Ta variable entityPlayer semble être null.
Donc event.harvester l’est aussi, je fais regarder vite fait. -
Eh bien, j’ai rajouter un
if(entityPlayer != null)Et ca s’emble marché
-
Ok parfait. Mais c’est quand même étrange que le joueur est null.
-
robin, je me permet de rebondir, car j’ai remarquer un bug similaire sur les condition du type :
if(entityPlayer.inventory.getCurrentItem() != null && entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.firePickaxe)J’ai personnellement était constamment obliger de séparer en deux condition distincte (d’abord vérifier si c’est null, et si ça ne l’est pas faire un second bloque condition avec la bonne condition) :
if(entityPlayer.inventory.getCurrentItem() != null) { if(entityPlayer.inventory.getCurrentItem().getItem() == IceNFire.firePickaxe) { // ici les fonction } } -
Les deux reviennent au même.
-
A l’exception que j’avais systématique un crash avec la premier méthode… Eclipse semblais effectuer les deux opérations séparement, puis vérifier le “ET” après, du coup il plantais comme il tentai de vérifier une variable null.
Ça pourra peu être dépanner quelqu’un si il ont un crash similaire ^^
-
Normalement non. Le code une fois compilé est sous la forme d’instructions qui se suivent, dans une condition s’il n’y a que des && et que la première condition est fausse, il passe directement à la suite.
