From a4c6f19b6b2bb852891f867ca3c96bd485e4b58b Mon Sep 17 00:00:00 2001 From: Shane Freeder Date: Sun, 11 Feb 2018 10:43:46 +0000 Subject: [PATCH] Extend Player Interact cancellation GUIs are opened on the client, meaning that the server cannot block them from opening, However, it is possible to close these GUIs from the server. Flower pots are also not updated on the client when interaction is cancelled, this patch also resolves this. diff --git a/src/main/java/net/minecraft/server/PlayerInteractManager.java b/src/main/java/net/minecraft/server/PlayerInteractManager.java index 5ec7f5819..24f14337a 100644 --- a/src/main/java/net/minecraft/server/PlayerInteractManager.java +++ b/src/main/java/net/minecraft/server/PlayerInteractManager.java @@ -468,6 +468,24 @@ public class PlayerInteractManager { ((EntityPlayer) entityhuman).playerConnection.sendPacket(new PacketPlayOutBlockChange(world, bottom ? blockposition.up() : blockposition.down())); } else if (blockdata.getBlock() instanceof BlockCake) { ((EntityPlayer) entityhuman).getBukkitEntity().sendHealthUpdate(); // SPIGOT-1341 - reset health for cake + // Paper start - extend Player Interact cancellation + } else if (blockdata.getBlock() instanceof BlockStructure) { + ((EntityPlayer) entityhuman).playerConnection.sendPacket(new PacketPlayOutCloseWindow()); + } else if (blockdata.getBlock() instanceof BlockCommand) { + ((EntityPlayer) entityhuman).playerConnection.sendPacket(new PacketPlayOutCloseWindow()); + } else if (blockdata.getBlock() instanceof BlockFlowerPot) { + // Send a block change to air and then send back the correct block, just to make the client happy + PacketPlayOutBlockChange packet = new PacketPlayOutBlockChange(this.world, blockposition); + packet.block = Blocks.AIR.getBlockData(); + this.player.playerConnection.sendPacket(packet); + + this.player.playerConnection.sendPacket(new PacketPlayOutBlockChange(this.world, blockposition)); + + TileEntity tileentity = this.world.getTileEntity(blockposition); + if (tileentity != null) { + player.playerConnection.sendPacket(tileentity.getUpdatePacket()); + } + // Paper end - extend Player Interact cancellation } ((EntityPlayer) entityhuman).getBukkitEntity().updateInventory(); // SPIGOT-2867 enuminteractionresult = (event.useItemInHand() != Event.Result.ALLOW) ?
