From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Owen1212055 <23108066+Owen1212055@users.noreply.github.com> Date: Sat, 25 Jun 2022 19:45:20 -0400 Subject: [PATCH] Send block entities after destroy prediction Minecraft's prediction system does not handle block entities, so if we are manually sending block entities during block breaking we need to set it after the prediction is finished. This fixes block entities not showing when cancelling the BlockBreakEvent. diff --git a/src/main/java/net/minecraft/server/level/ServerPlayerGameMode.java b/src/main/java/net/minecraft/server/level/ServerPlayerGameMode.java index bf9b185e3defb496022c20ec60a84a4f6f99d5be..4e1ed252bf400ec991f95b02984f01a9689f2989 100644 --- a/src/main/java/net/minecraft/server/level/ServerPlayerGameMode.java +++ b/src/main/java/net/minecraft/server/level/ServerPlayerGameMode.java @@ -62,6 +62,8 @@ public class ServerPlayerGameMode { private BlockPos delayedDestroyPos; private int delayedTickStart; private int lastSentState; + public boolean captureSentBlockEntities = false; // Paper + public boolean capturedBlockEntity = false; // Paper public ServerPlayerGameMode(ServerPlayer player) { this.gameModeForPlayer = GameType.DEFAULT_MODE; @@ -188,10 +190,7 @@ public class ServerPlayerGameMode { this.player.connection.send(new ClientboundBlockUpdatePacket(pos, this.level.getBlockState(pos))); this.debugLogging(pos, false, sequence, "may not interact"); // Update any tile entity data for this block - BlockEntity tileentity = this.level.getBlockEntity(pos); - if (tileentity != null) { - this.player.connection.send(tileentity.getUpdatePacket()); - } + capturedBlockEntity = true; // Paper - send block entity after predicting // CraftBukkit end return; } @@ -202,10 +201,7 @@ public class ServerPlayerGameMode { // Let the client know the block still exists this.player.connection.send(new ClientboundBlockUpdatePacket(this.level, pos)); // Update any tile entity data for this block - BlockEntity tileentity = this.level.getBlockEntity(pos); - if (tileentity != null) { - this.player.connection.send(tileentity.getUpdatePacket()); - } + capturedBlockEntity = true; // Paper - send block entity after predicting return; } // CraftBukkit end @@ -389,10 +385,12 @@ public class ServerPlayerGameMode { } // Update any tile entity data for this block + if (!captureSentBlockEntities) { // Paper - Toggle this location for capturing as this is used for api BlockEntity tileentity = this.level.getBlockEntity(pos); if (tileentity != null) { this.player.connection.send(tileentity.getUpdatePacket()); } + } else {capturedBlockEntity = true;} // Paper end return false; } } diff --git a/src/main/java/net/minecraft/server/network/ServerGamePacketListenerImpl.java b/src/main/java/net/minecraft/server/network/ServerGamePacketListenerImpl.java index 95966fdddc81dcc4e65b075a4df6d5dd9af4e65a..7b6c3d1feeb390485e5ef5507e6dae3992155212 100644 --- a/src/main/java/net/minecraft/server/network/ServerGamePacketListenerImpl.java +++ b/src/main/java/net/minecraft/server/network/ServerGamePacketListenerImpl.java @@ -1783,8 +1783,28 @@ public class ServerGamePacketListenerImpl extends ServerCommonPacketListenerImpl return; } // Paper end - Don't allow digging in unloaded chunks + // Paper start - send block entities after prediction + this.player.gameMode.capturedBlockEntity = false; + this.player.gameMode.captureSentBlockEntities = true; + // Paper end - send block entities after prediction this.player.gameMode.handleBlockBreakAction(blockposition, packetplayinblockdig_enumplayerdigtype, packet.getDirection(), this.player.level().getMaxBuildHeight(), packet.getSequence()); this.player.connection.ackBlockChangesUpTo(packet.getSequence()); + // Paper start - send block entities after prediction + this.player.gameMode.captureSentBlockEntities = false; + // If a block entity was modified speedup the block change ack to avoid the block entity + // being overriden. + if (this.player.gameMode.capturedBlockEntity) { + // manually tick + this.send(new ClientboundBlockChangedAckPacket(this.ackBlockChangesUpTo)); + this.player.connection.ackBlockChangesUpTo = -1; + + this.player.gameMode.capturedBlockEntity = false; + BlockEntity tileentity = this.player.level().getBlockEntity(blockposition); + if (tileentity != null) { + this.player.connection.send(tileentity.getUpdatePacket()); + } + } + // Paper end - send block entities after prediction return; default: throw new IllegalArgumentException("Invalid player action");
