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. == AT == public net.minecraft.world.level.block.entity.BlockEntityType validBlocks 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 6e24673a793017ee857cf75bf9a74105ce76b773..e3c5f99b3ad91a9bb454f9ab95b1ccff0bb7b34c 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 @@ -371,7 +371,7 @@ 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 92133f16c192f5caf9962a08401ff914550747f8..397eb1a101bd60f49dbb2fa8eddf28f6f233167f 100644 --- a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockEntityState.java +++ b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockEntityState.java @@ -20,7 +20,7 @@ import org.bukkit.persistence.PersistentDataContainer; import org.jetbrains.annotations.NotNull; import org.jetbrains.annotations.Nullable; -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; @@ -181,14 +181,10 @@ public class CraftBlockEntityState extends CraftBlockStat } @Override - public CraftBlockEntityState copy() { - return new CraftBlockEntityState<>(this, null); - } + public abstract CraftBlockEntityState copy(); // Paper - make abstract @Override - public CraftBlockEntityState copy(Location location) { - return new CraftBlockEntityState<>(this, location); - } + public abstract CraftBlockEntityState copy(Location location); // Paper - make abstract // Paper start @Override diff --git a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java index 83ac5fc6cbbd249b5865ab203b150f53f01c9f05..6a25916aec7c8e0bc5cc18e3e06c6e07e0804380 100644 --- a/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java +++ b/src/main/java/org/bukkit/craftbukkit/block/CraftBlockStates.java @@ -22,6 +22,7 @@ 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.BrushableBlockEntity; import net.minecraft.world.level.block.entity.CalibratedSculkSensorBlockEntity; @@ -118,228 +119,65 @@ 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.
