Résolu Transformer un item en un autre comme les fioles
-
Bonjour, je me présente, Eryah. je m’attaque enfin , à l’item que je voulait créer un PREMIER, car c’est lui qui m’a donné envie de faire ce mod : La bouteille d’air.
Elle est inutile sur terre, mais dans l’eau, elle permet de regagner entièrement sa jauge d’oxygène. Pour l’obtenir, il suffit de right click dans l’air avec une bouteille présice. Mais…
Je n’arrive pas à faire un sorte de cela
J’ai pris le code de la bouteille de verre de base de MinecraftCode de la bouteille hermétique ( Partie concernée)
public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn) { MovingObjectPosition movingobjectposition = this.getMovingObjectPositionFromPlayer(worldIn, playerIn, true); if (movingobjectposition == null) { return itemStackIn; } else { if (movingobjectposition.typeOfHit == MovingObjectPosition.MovingObjectType.BLOCK) { BlockPos blockpos = movingobjectposition.getBlockPos(); if (!worldIn.isBlockModifiable(playerIn, blockpos)) { return itemStackIn; } if (!playerIn.canPlayerEdit(blockpos.offset(movingobjectposition.sideHit), movingobjectposition.sideHit, itemStackIn)) { return itemStackIn; } if (worldIn.getBlockState(blockpos).getBlock().getMaterial() == Material.air) { --itemStackIn.stackSize; playerIn.triggerAchievement(StatList.objectUseStats[Item.getIdFromItem(this)]); if (itemStackIn.stackSize <= 0) { return new ItemStack(Items.potionitem); } if (!playerIn.inventory.addItemStackToInventory(new ItemStack(Items.potionitem))) { playerIn.dropPlayerItemWithRandomChoice(new ItemStack(Items.potionitem, 1, 0), false); } } } return itemStackIn; }L’item destiné a étre obtenu n’existant pas encore, je laisse le drop du code de base ( fiole d’eau )
-
À mon avis cela ne fonctionne pas car
movingobjectposition.typeOfHit n’est pas du type MovingObjectPosition.MovingObjectType.BLOCK quand on clic dans le vide.
Ajoute System.out.println(movingobjectposition.typeOfHit.toString()); avant la condition et fait un clic droit dans le vide pour voir ce qu’il vaut. -
Je n ai pas eclipse sous mes yeux mais je crois que c’est plutôt
MovingObjectType.Air -
public static enum MovingObjectType { MISS, BLOCK, ENTITY; private static final String __OBFID = "CL_00000611"; }Non, c’est MISS
-
Ah j avais cru que c’était en 1.7.10 autant pour moi.
-
J’ai tenté d’allegé le code ( J’ai peut-etre fait de la merde :S ) car je trouvait toute ses conditions inutiles.
Sinon, je ne sais pas si j’ai bien placé le system.out.printIn, car il ne fonctionne pasPartie concernée du code
public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn) { MovingObjectPosition movingobjectposition = this.getMovingObjectPositionFromPlayer(worldIn, playerIn, true); System.out.println(movingobjectposition.typeOfHit.toString()); if (movingobjectposition.typeOfHit == MovingObjectPosition.MovingObjectType.BLOCK) { BlockPos blockpos = movingobjectposition.getBlockPos(); if (worldIn.getBlockState(blockpos).getBlock().getMaterial() == Material.air) { –itemStackIn.stackSize; playerIn.triggerAchievement(StatList.objectUseStats[Item.getIdFromItem(this)]); if (itemStackIn.stackSize <= 0) { return new ItemStack(Items.potionitem); } if (!playerIn.inventory.addItemStackToInventory(new ItemStack(Items.potionitem))) { playerIn.dropPlayerItemWithRandomChoice(new ItemStack(Items.potionitem, 1, 0), false); } } } return itemStackIn; } }
Petite erreur lors de la création de l’item en question

Tu l’as mit au bon endroit. Il n’affiche rien ?
Essayes d’ajouter @Override au dessus de ta fonction ? -
Toujours rien
-
Pas possible. Il faudrait forcement avoir quelque chose dans les logs. Envoie toute ta classe.

bottleherm = new Item().setUnlocalizedName(“bottleherm”).setCreativeTab(UsefulthingsMod.UTTab);
–’
Est-ce que tu comprends au moins cette ligne ?!
Ici, tu initialise ton item avec la classe Item. Donc il prend ce qu’il y a dans la casse Item et ignore complètement ta classe.Il faut faire :
bottleherm = new BottleHerm().setUnlocalizedName(“bottleherm”).setCreativeTab(UsefulthingsMod.UTTab); -
Ah… Eh bien je vais faire la modification sur la totalité des items de mon mod ^^’
C’est le code de MrCrayFish, et moi comme un con, je vérifiais même pas ses codes, que je recopiait aveuglément…

Bon c’est bien ce que je pensais.
movingobjectposition est null quand on clic dans le vide.
Du-coup il faut faire :public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn) { MovingObjectPosition movingobjectposition = this.getMovingObjectPositionFromPlayer(worldIn, playerIn, true); System.out.println(movingobjectposition.typeOfHit.toString()); if (movingobjectposition == null) { –itemStackIn.stackSize; playerIn.triggerAchievement(StatList.objectUseStats[Item.getIdFromItem(this)]); if (itemStackIn.stackSize <= 0) { return new ItemStack(Items.potionitem); } if (!playerIn.inventory.addItemStackToInventory(new ItemStack(Items.potionitem))) { playerIn.dropPlayerItemWithRandomChoice(new ItemStack(Items.potionitem, 1, 0), false); } } return itemStackIn; } } -
Il y a une erreur invisible… sur public ItemStack onItemRightClick(ItemStack itemStackIn, World worldIn, EntityPlayer playerIn)
Multiple markers at this line- Syntax error on token “Invalid Character”, delete
this token - overrides
net.minecraft.item.Item.onItemRightClick
je dis invisible, car il n’y a pas le soulignement rouge
- Syntax error on token “Invalid Character”, delete
-
Ré-écrit à la main la partie qui bug. Des fois les copier/coller depuis le fofo fait des trucs étrange.
-
Il faut également supprimer le printIn, sinon cela ne fonctionne pas
Plus d’erreur, je lance mon client
j’espère que cela va fonctionner !Ça fonctionne
Merci beaucoup robin pour ton aide
