From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Sat, 6 Apr 2019 10:16:48 -0400 Subject: [PATCH] Optimize Captured TileEntity Lookup upstream was doing a containsKey/get pattern, and always doing it at that. that scenario is only even valid if were in the middle of a block place. Optimize to check if the captured list even has values in it, and also to just do a get call since the value can never be null. diff --git a/src/main/java/net/minecraft/world/level/Level.java b/src/main/java/net/minecraft/world/level/Level.java index b10c93cbcf264a3e13d48f30a2c09ae5568a510e..3fdec0ff323ac94517f1ab9a13764a8959148127 100644 --- a/src/main/java/net/minecraft/world/level/Level.java +++ b/src/main/java/net/minecraft/world/level/Level.java @@ -998,9 +998,12 @@ public abstract class Level implements LevelAccessor, AutoCloseable { @Nullable public BlockEntity getBlockEntity(BlockPos blockposition, boolean validate) { - if (this.capturedTileEntities.containsKey(blockposition)) { - return this.capturedTileEntities.get(blockposition); + // Paper start - Optimize capturedTileEntities lookup + net.minecraft.world.level.block.entity.BlockEntity blockEntity; + if (!this.capturedTileEntities.isEmpty() && (blockEntity = this.capturedTileEntities.get(blockposition)) != null) { + return blockEntity; } + // Paper end // CraftBukkit end return this.isOutsideBuildHeight(blockposition) ? null : (!this.isClientSide && !io.papermc.paper.util.TickThread.isTickThread() ? null : this.getChunkAt(blockposition).getBlockEntity(blockposition, LevelChunk.EntityCreationType.IMMEDIATE)); // Paper - rewrite chunk system }
