From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: lexikiq Date: Mon, 21 Jun 2021 23:21:58 -0400 Subject: [PATCH] Preserve overstacked loot Preserves overstacked items in loot tables, such as shulker box drops, to prevent the items from being deleted (as they'd overflow past the bounds of the container)-- or worse, causing chunk bans via the large amount of NBT created by unstacking the items. Fixes GH-5140 and GH-4748. diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index 0a611df010c9c5e621f10ae55a0ce66fd0cae0e2..0906a2d410e11cb352b13e5c0390560085b8f254 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -932,6 +932,11 @@ public class PaperWorldConfig { allowPlayerCrammingDamage = getBoolean("allow-player-cramming-damage", allowPlayerCrammingDamage); } + public boolean splitOverstackedLoot = true; + private void splitOverstackedLoot() { + splitOverstackedLoot = getBoolean("split-overstacked-loot", splitOverstackedLoot); + } + private Table sensorTickRates; private Table behaviorTickRates; private void tickRates() { diff --git a/src/main/java/net/minecraft/world/level/storage/loot/LootTable.java b/src/main/java/net/minecraft/world/level/storage/loot/LootTable.java index db80db9d6382dd4748aa8f27dd3c3d3ae9fe9380..9827229d125addcfec8b0025724b9a4570c40a12 100644 --- a/src/main/java/net/minecraft/world/level/storage/loot/LootTable.java +++ b/src/main/java/net/minecraft/world/level/storage/loot/LootTable.java @@ -54,9 +54,17 @@ public class LootTable { this.compositeFunction = LootItemFunctions.compose(functions); } + @Deprecated // Paper - preserve overstacked items public static Consumer createStackSplitter(Consumer lootConsumer) { + // Paper start - preserve overstacked items + return createStackSplitter(lootConsumer, null); + } + + public static Consumer createStackSplitter(Consumer lootConsumer, @org.jetbrains.annotations.Nullable net.minecraft.server.level.ServerLevel world) { + boolean skipSplitter = world != null && !world.paperConfig.splitOverstackedLoot; + // Paper end return (itemstack) -> { - if (itemstack.getCount() < itemstack.getMaxStackSize()) { + if (skipSplitter || itemstack.getCount() < itemstack.getMaxStackSize()) { // Paper - preserve overstacked items lootConsumer.accept(itemstack); } else { int i = itemstack.getCount(); @@ -93,7 +101,7 @@ public class LootTable { } public void getRandomItems(LootContext context, Consumer lootConsumer) { - this.getRandomItemsRaw(context, LootTable.createStackSplitter(lootConsumer)); + this.getRandomItemsRaw(context, LootTable.createStackSplitter(lootConsumer, context.getLevel())); // Paper - preserve overstacked items } public List getRandomItems(LootContext context) { diff --git a/src/main/java/net/minecraft/world/level/storage/loot/functions/SetContainerContents.java b/src/main/java/net/minecraft/world/level/storage/loot/functions/SetContainerContents.java index 6d63c5318e1711a27b254db950ae7576d333ad47..6b5e481980751ed83cda7badc160b738d5c56af9 100644 --- a/src/main/java/net/minecraft/world/level/storage/loot/functions/SetContainerContents.java +++ b/src/main/java/net/minecraft/world/level/storage/loot/functions/SetContainerContents.java @@ -39,7 +39,7 @@ public class SetContainerContents extends LootItemConditionalFunction { NonNullList nonNullList = NonNullList.create(); this.entries.forEach((entry) -> { entry.expand(context, (choice) -> { - choice.createItemStack(LootTable.createStackSplitter(nonNullList::add), context); + choice.createItemStack(LootTable.createStackSplitter(nonNullList::add, context.getLevel()), context); // Paper - preserve overstacked items }); }); CompoundTag compoundTag = new CompoundTag();
