From 23f3d0db1d1c00b42cd80431fafacc551af8056a 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/server/World.java b/src/main/java/net/minecraft/server/World.java index 0324191551..177ea8f4cd 100644 --- a/src/main/java/net/minecraft/server/World.java +++ b/src/main/java/net/minecraft/server/World.java @@ -1049,12 +1049,13 @@ public abstract class World implements IIBlockAccess, GeneratorAccess, AutoClose return null; } else { // CraftBukkit start - if (capturedTileEntities.containsKey(blockposition)) { - return capturedTileEntities.get(blockposition); + TileEntity tileentity = null; // Paper + if (!capturedTileEntities.isEmpty() && (tileentity = capturedTileEntities.get(blockposition)) != null) { // Paper + return tileentity; // Paper } // CraftBukkit end - TileEntity tileentity = null; + //TileEntity tileentity = null; // Paper - move up if (this.tickingTileEntities) { tileentity = this.B(blockposition); -- 2.21.0
