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 b0174aedb7358af1e80278e2f5f13e00c35ab3c6..d62181bd8bccfcfdd7da8f635bdf7ebc36294705 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 @@ -250,7 +250,7 @@ public abstract class BlockEntity { // 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/CraftBlockEntityState.java b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockEntityState.java index 87c25170fbe8b0591d452612496ee1a627138de7..a2894f02ceb7c58f6eafe055e1ff47b197b100f2 100644 --- a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockEntityState.java +++ b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockEntityState.java @@ -6,7 +6,7 @@ import org.bukkit.World; import org.bukkit.block.TileState; import org.bukkit.persistence.PersistentDataContainer; -public class CraftBlockEntityState extends CraftBlockState implements TileState { +public abstract class CraftBlockEntityState extends CraftBlockState implements TileState { // Paper - revert upstream's revert of the block state changes private final T tileEntity; private final T snapshot; diff --git a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java index e609cfeaf5aa6807f57360dde9b0dccf40a23eb1..594b071cbb25d6e8f184c8558c3d1f490fe4712f 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; @@ -108,187 +109,57 @@ public final class CraftBlockStates { private static final BlockStateFactory DEFAULT_FACTORY = new BlockStateFactory(CraftBlockState.class) { @Override public CraftBlockState createBlockState(World world, BlockPos blockPosition, net.minecraft.world.level.block.state.BlockState blockData, BlockEntity tileEntity) { - // SPIGOT-6754, SPIGOT-6817: Restore previous behaviour for tile entities with removed blocks (loot generation post-destroy) - if (tileEntity != null) { - // block with unhandled TileEntity: - return new CraftBlockEntityState<>(world, tileEntity); - } + // Paper - revert upstream's revert of the block state changes.
