From 73f423d4b038df91294e25f806ab2836b290bfbf Mon Sep 17 00:00:00 2001 From: Shane Freeder Date: Thu, 16 Nov 2017 12:12:41 +0000 Subject: [PATCH] use CB BlockState implementations for captured blocks When modifying the world, CB will store a copy of the affected blocks in order to restore their state in the case that the event is cancelled. This change only modifies the collection of blocks in the world by normal means, e.g. not during tree population, as the potentially marginal overheads would serve no advantage. CB was using a CraftBlockState for all blocks, which causes issues should any block that uses information beyond a data ID would suffer from missing information, e.g. Skulls. By using CBs CraftBlock#getState(), we will maintain a proper copy of the blockstate that will be valid for restoration, as opposed to dropping information on restoration when the event is cancelled. diff --git a/src/main/java/net/minecraft/server/World.java b/src/main/java/net/minecraft/server/World.java index 22f1d9e27b..e780f7af40 100644 --- a/src/main/java/net/minecraft/server/World.java +++ b/src/main/java/net/minecraft/server/World.java @@ -348,7 +348,7 @@ public abstract class World implements IIBlockAccess, GeneratorAccess, AutoClose // CraftBukkit start - capture blockstates CraftBlockState blockstate = null; if (this.captureBlockStates) { - blockstate = org.bukkit.craftbukkit.block.CraftBlockState.getBlockState(this, blockposition, i); + blockstate = (CraftBlockState) world.getBlockAt(blockposition.getX(), blockposition.getY(), blockposition.getZ()).getState(); // Paper - use CB getState to get a suitable snapshot this.capturedBlockStates.add(blockstate); } // CraftBukkit end -- 2.22.0
