From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Aikar Date: Wed, 6 Feb 2019 00:20:33 -0500 Subject: [PATCH] BlockDestroyEvent Adds an event for when the server is going to destroy a current block, potentially causing it to drop. This event can be cancelled to avoid the block destruction, such as preventing signs from popping when floating in the air. This can replace many uses of BlockPhysicsEvent diff --git a/src/main/java/net/minecraft/world/level/Level.java b/src/main/java/net/minecraft/world/level/Level.java index 0663aa74688104c551e8ef52b01947dacf95bb22..f7fccb4761e829a2a1d431f56cfb4288ae0bbd2d 100644 --- a/src/main/java/net/minecraft/world/level/Level.java +++ b/src/main/java/net/minecraft/world/level/Level.java @@ -28,6 +28,7 @@ import net.minecraft.nbt.CompoundTag; import net.minecraft.network.protocol.Packet; import net.minecraft.resources.ResourceKey; import net.minecraft.resources.ResourceLocation; +import net.minecraft.server.MCUtil; import net.minecraft.server.MinecraftServer; import net.minecraft.server.level.ChunkHolder; import net.minecraft.server.level.ServerLevel; @@ -564,8 +565,20 @@ public abstract class Level implements LevelAccessor, AutoCloseable { return false; } else { FluidState fluid = this.getFluidState(pos); + // Paper start - while the above setAir method is named same and looks very similar + // they are NOT used with same intent and the above should not fire this event.
