(Post-Compilation) Crash au lancement

bin4r1s

Bonjour, après avoir compilé mon mod avec la commande ‘gradlew build’ et récupéré les sources dans le dossier build (assets, packages et mcmod.info, je précise au cas où il y aurai une erreur), je lance tout naturellement Minecraft Forge (le normal) pour tester si mon mod marche. Et là :

J’ai beau chercher l’erreur avec dragonEgg (Material.class) mais je ne trouve pas…

Un peu d’aide svp ? :huh:

zery59

Pour commencer, vire :

private static final String __OBFID = "CL_00000232";

Ensuite, le material de ton block est mal construis (je pense) :

public BlockDragonEgg()
{
    super(Material.dragonEgg);
    this.setBlockBounds(0.0625F, 0.0F, 0.0625F, 0.9375F, 1.0F, 0.9375F);
}

Mets plutôt :

public BlockDragonEgg(Material material)
{
    super(material);
    this.setBlockBounds(0.0625F, 0.0F, 0.0625F, 0.9375F, 1.0F, 0.9375F);
}

Du coup, dans ta classe principale, change :

    fireDragonEgg = new BlockDragonEgg()

En :

    fireDragonEgg = new BlockDragonEgg(Material.dragonEgg)

Superloup10

Cela ne change strictement rien à la définition du Material. Ensuite, à quoi correspond la ligne 22 de BlockDragonEgg.

bin4r1s

@zery59 Merci mais ça ne marche toujours pas (même erreur)

@Superloup10 La ligne 22 ? C’est une accolade x)
En fait, le code est totalement copié des classes de Minecraft car si j’utilisait l’originale, le jeu plantait encore à cause de setHardness() et setResistance().

Superloup10

Envois ta class par pastebin.

gradlew build
Et le jar se trouve dans build/libs/ il s’appelle modid-1.0.jar par défaut.

Si tu prends le fichier comme tu as fait ça ne fonctionne pas.

Ah merci ça marche, sujet résolu.
