From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Wed, 6 Oct 2021 20:50:48 -0700 Subject: [PATCH] Fix upstreams block state factories Sometimes, blocks are changed and then logic is called before the associated tile entity is removed. When this happens, the factories were relying on the block at the position, not the tile entity. This change prioritizes using the tile entity type to determine the block state factory and falls back on the material type of the block at that location. diff --git a/src/main/java/net/minecraft/world/level/block/entity/BlockEntity.java b/src/main/java/net/minecraft/world/level/block/entity/BlockEntity.java index 0e37da7227eaba0d089e5bd136eca088ab2b5eb3..5601d0c2fe635a2a4f073c333531e1a8adf1833c 100644 --- a/src/main/java/net/minecraft/world/level/block/entity/BlockEntity.java +++ b/src/main/java/net/minecraft/world/level/block/entity/BlockEntity.java @@ -270,7 +270,7 @@ public abstract class BlockEntity implements io.papermc.paper.util.KeyedObject { // Paper end if (this.level == null) return null; org.bukkit.block.Block block = this.level.getWorld().getBlockAt(this.worldPosition.getX(), this.worldPosition.getY(), this.worldPosition.getZ()); - if (block.getType() == org.bukkit.Material.AIR) return null; + // if (block.getType() == org.bukkit.Material.AIR) return null; // Paper - actually get the tile entity if it still exists org.bukkit.block.BlockState state = block.getState(useSnapshot); // Paper if (state instanceof InventoryHolder) return (InventoryHolder) state; return null; diff --git a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java index b794e04036df00dd9633b9bd808591f499238387..0356c33bc14bef73a7468d5360ea5cd309d5f623 100644 --- a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java +++ b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java @@ -19,6 +19,7 @@ import net.minecraft.world.level.block.entity.BeehiveBlockEntity; import net.minecraft.world.level.block.entity.BellBlockEntity; import net.minecraft.world.level.block.entity.BlastFurnaceBlockEntity; import net.minecraft.world.level.block.entity.BlockEntity; +import net.minecraft.world.level.block.entity.BlockEntityType; // Paper import net.minecraft.world.level.block.entity.BrewingStandBlockEntity; import net.minecraft.world.level.block.entity.CampfireBlockEntity; import net.minecraft.world.level.block.entity.ChestBlockEntity; @@ -106,183 +107,54 @@ public final class CraftBlockStates { @Override public CraftBlockState createBlockState(World world, BlockPos blockPosition, net.minecraft.world.level.block.state.BlockState blockData, BlockEntity tileEntity) { // When a block is being destroyed, the TileEntity may temporarily still exist while the block's type has already been set to AIR.
