From f67c56f2cf2284b18a8a76b51cbfb5af1b82597e Mon Sep 17 00:00:00 2001 From: Andre LeBlanc Date: Sat, 6 Apr 2013 12:00:31 -0400 Subject: [PATCH] Make AnvilInventory.getItem() use both containers. Fixes BUKKIT-2788 The AnvilInventory reports its size as the sum of the ingredient and result inventories, but when trying to access the slots, only the ingredient inventory is used, leading to an ArrayIndexOutOfBounds exception. This change overrides getItem(I) and setItem(I) to use both inventories, with the slot number adjusted based on their size. diff --git a/src/main/java/org/bukkit/craftbukkit/inventory/CraftInventoryAnvil.java b/src/main/java/org/bukkit/craftbukkit/inventory/CraftInventoryAnvil.java index a91d81a..46a1d38 100644 --- a/src/main/java/org/bukkit/craftbukkit/inventory/CraftInventoryAnvil.java +++ b/src/main/java/org/bukkit/craftbukkit/inventory/CraftInventoryAnvil.java @@ -1,7 +1,9 @@ package org.bukkit.craftbukkit.inventory; import net.minecraft.server.IInventory; + import org.bukkit.inventory.AnvilInventory; +import org.bukkit.inventory.ItemStack; public class CraftInventoryAnvil extends CraftInventory implements AnvilInventory { private final IInventory resultInventory; @@ -20,6 +22,26 @@ public class CraftInventoryAnvil extends CraftInventory implements AnvilInventor } @Override + public ItemStack getItem(int slot) { + if (slot < getIngredientsInventory().getSize()) { + net.minecraft.server.ItemStack item = getIngredientsInventory().getItem(slot); + return item == null ? null : CraftItemStack.asCraftMirror(item); + } else { + net.minecraft.server.ItemStack item = getResultInventory().getItem(slot - getIngredientsInventory().getSize()); + return item == null ? null : CraftItemStack.asCraftMirror(item); + } + } + + @Override + public void setItem(int index, ItemStack item) { + if (index < getIngredientsInventory().getSize()) { + getIngredientsInventory().setItem(index, (item == null ? null : CraftItemStack.asNMSCopy(item))); + } else { + getResultInventory().setItem((index - getIngredientsInventory().getSize()), (item == null ? null : CraftItemStack.asNMSCopy(item))); + } + } + + @Override public int getSize() { return getResultInventory().getSize() + getIngredientsInventory().getSize(); } -- 1.8.1.2
