Il faut que tu vérifie que event.getType() != null et si ça marche pas envoie ton code avec les imports car sinon les lignes ne sont pas juste avec le crash report

[DailyCraft]

il faut que tu donne une valeur de base à amountType

[robin4002]

C’est le cas et on ne peut pas avoir de NPE sur un int de toute façon.
C’est fontRender qui est null.
à mon avis au moment où ta classe est utilisé, this.mc.fontRenderer vaut encore null.

Fais comme ça :

drawCenteredString(this.mc.fontRenderer, this.amountTiles + "%", 0,100, 11);

[Drastic]

@robin4002 merci !
Juste une question : Comment je peux faire pour afficher un item sur l’écran (moi un coffre) dans mon gui ?
Je crois y’a un truc genre ItemRenderer.

Merci

[Drastic]

@robin4002 par contre quand je fais le code pour que le gui s’affiche uniquement lorsque je tiens l’item, plus rien n’est affiché.

if(event.getType() == RenderGameOverlayEvent.ElementType.EXPERIENCE && mc.player.getHeldItem(EnumHand.MAIN_HAND) == new ItemStack(ItemInit.radar)/*&& ItemRadar.isUsed == 1*/)
        {
//code
        }

[robin4002]

Parcequ’il ne faut pas comparer des itemstack avec ==
L’opérateur == vérifies uniquement le contenu dans le stack (je parle l’espace mémoire, pas de l’itemstack).
Donc ça fonctionne très bien pour les types primitifs (int, boolean, float, double, short, long, char) mais sur les objets, cela compare uniquement s’il s’agit de la même référence.
En conséquence un objet == new Quelquechose sera toujours false, car ce sont forcément deux références différentes.
== ne renvoie que vrai avec des objets s’il s’agit de la même référence. Typiquement dans Minecraft les blocs ou items sont des singletons, donc on peut les comparer avec un ==.

Pour comparer le contenu des objets, il existe souvent une méthode .equals.
Par exemple stack.equals(new ItemStack(ItemInit.radar)). Mais cette méthode compare de façon profonde le contenu, ce qui nécessite plus de perf et surtout va aussi vérifier la quantité de l’itemstack, le tag NBT, etc. Donc par exemple ici, si stack est enchanté ou si on a 2 item en main au lieu d’un, ça ne fonctionne plus.

Pour ce cas (et la majorité des comparaisons d’item / bloc dans le jeu), il faut comparer l’item qui se trouve dans l’itemstack : mc.player.getHeldItem(EnumHand.MAIN_HAND).getItem() == ItemInit.radar

[DailyCraft]

En gros faut oublier == et mettre que des .equals() ?

[robin4002]

Je pense que tu n’as pas bien lu mon message.
J’ai dit que cela dépend de ce qu’on veut faire.

Encore merci et désolé du dérangement.

[robin4002]

Retires la double for à la ligne 47, elle n’a rien à faire là.
Si tu bocule sur toute la durabilité c’est normal de tomber à 0.

[Drastic]

@robin4002 merci je vais tester. En plus c’est bête car onUpdate fais deja une update par tick

[DailyCraft]

pas le temps de répondre, trop rapide @robin4002 …

[Drastic]

@robin4002 désolé de te déranger encore mais j’ai un dernier soucis :
je veux créer une durabilité (ce qui est fait ) et l’afficher sous format h:m:s mais je ne sais pas exactement comment.

@robin4002 merci. Mais juste, je sais pas si c’est moi qui suis bête mais je n’arrive pas à récupérer la durabilité…

Bon, après de lonnnngues recherches voici le code de l’unclaim finder en 1.12.2 avec 1h30 de durabilité :
Classe de l’item :

public class ItemRadar extends Item implements IHasModel

Bonne journée et merci à @DailyCraft et @robin4002 pour leur aide !
