Crash avec les dalles
-
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 :

Salut, dans le crash sur eclipse clic sur : java:79 à cette endroit : at fr.khantyer.myblock.common.ItemDalleBuche.onItemUse(ItemDalleBuche.java:79)
ça devrait te sélectionner une ligne du code, envoie-la -
Voici la ligne en question :
.getCollisionBoundingBoxFromPool(world, x, y, z))Elle est incluse dans cette condition :
if (world.checkNoEntityCollision(this.doubleSlab .getCollisionBoundingBoxFromPool(world, x, y, z)) && world.setBlock(x, y, z, this.doubleSlab, k1, 3)) -
L’objet doubleSlab est null. Je peux avoir ta classe principale ?
-
public static Block dalleBuche, doubleDalleBuche; @EventHandler public void preInit(FMLPreInitializationEvent event) { dalleBuche = new DalleBuche(false, Material.wood).setBlockName("Dalle_Buche").setCreativeTab(CreativeTabs.tabBlock); GameRegistry.registerBlock(dalleBuche, ItemDalleBuche.class, "dalle_buche"); doubleDalleBuche = new DalleBuche(true, Material.wood).setBlockName("Double_Dalle_Buche"); GameRegistry.registerBlock(doubleDalleBuche, ItemDalleBuche.class, "double_dalle_buche"); }Sachant que this.doubleSlab est initialisée dans le constructeur :
this.doubleSlab = ModMyBlock.doubleDalleBuche; -
Fait comme ça :
@EventHandler public void preInit(FMLPreInitializationEvent event) { dalleBuche = new DalleBuche(false, Material.wood).setBlockName("Dalle_Buche").setCreativeTab(CreativeTabs.tabBlock); doubleDalleBuche = new DalleBuche(true, Material.wood).setBlockName("Double_Dalle_Buche"); GameRegistry.registerBlock(dalleBuche, ItemDalleBuche.class, "dalle_buche"); GameRegistry.registerBlock(doubleDalleBuche, ItemDalleBuche.class, "double_dalle_buche"); }L’ordre est important, sinon la classe ItemDalleBuche est initialisé alors que doubleDalleBuche est encore null.
