From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Fri, 9 Jul 2021 13:50:48 -0700 Subject: [PATCH] Fix commands from signs not firing command events This patch changes sign command logic so that `run_command` click events: - are logged to the console - fire PlayerCommandPreprocessEvent - work with double-slash commands like `//wand` - sends failure messages to the player who clicked the sign diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java index 75988ff014e40b248312d13d27f677882211d607..449093429d0c15dedc2a135a49d570c104f2f563 100644 --- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java +++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java @@ -859,4 +859,9 @@ public class PaperWorldConfig { private void fixInvulnerableEndCrystalExploit() { fixInvulnerableEndCrystalExploit = getBoolean("unsupported-settings.fix-invulnerable-end-crystal-exploit", fixInvulnerableEndCrystalExploit); } + + public boolean showSignClickCommandFailureMessagesToPlayer = false; + private void showSignClickCommandFailureMessagesToPlayer() { + showSignClickCommandFailureMessagesToPlayer = getBoolean("show-sign-click-command-failure-msgs-to-player", showSignClickCommandFailureMessagesToPlayer); + } } diff --git a/src/main/java/io/papermc/paper/commands/DelegatingCommandSource.java b/src/main/java/io/papermc/paper/commands/DelegatingCommandSource.java new file mode 100644 index 0000000000000000000000000000000000000000..1f6747d7a4c33f0ee7b0dc2120081bb87a855d35 --- /dev/null +++ b/src/main/java/io/papermc/paper/commands/DelegatingCommandSource.java @@ -0,0 +1,42 @@ +package io.papermc.paper.commands; + +import net.minecraft.commands.CommandSource; +import net.minecraft.commands.CommandSourceStack; +import net.minecraft.network.chat.Component; +import org.bukkit.command.CommandSender; + +import java.util.UUID; + +public class DelegatingCommandSource implements CommandSource { + + private final CommandSource delegate; + + public DelegatingCommandSource(CommandSource delegate) { + this.delegate = delegate; + } + + @Override + public void sendMessage(Component message, UUID sender) { + delegate.sendMessage(message, sender); + } + + @Override + public boolean acceptsSuccess() { + return delegate.acceptsSuccess(); + } + + @Override + public boolean acceptsFailure() { + return delegate.acceptsFailure(); + } + + @Override + public boolean shouldInformAdmins() { + return delegate.shouldInformAdmins(); + } + + @Override + public CommandSender getBukkitSender(CommandSourceStack wrapper) { + return delegate.getBukkitSender(wrapper); + } +} diff --git a/src/main/java/net/minecraft/world/level/block/entity/SignBlockEntity.java b/src/main/java/net/minecraft/world/level/block/entity/SignBlockEntity.java index 615c4f9d9841f7ddc3e5c854e90f41c3905c2e8f..6371176fba41218a209ea59b4cafe5b2d4a685fd 100644 --- a/src/main/java/net/minecraft/world/level/block/entity/SignBlockEntity.java +++ b/src/main/java/net/minecraft/world/level/block/entity/SignBlockEntity.java @@ -40,6 +40,7 @@ public class SignBlockEntity extends BlockEntity implements CommandSource { // C private boolean renderMessagedFiltered; private DyeColor color; private boolean hasGlowingText; + private static final org.apache.logging.log4j.Logger LOGGER = org.apache.logging.log4j.LogManager.getLogger(); public SignBlockEntity(BlockPos pos, BlockState state) { super(BlockEntityType.SIGN, pos, state); @@ -224,7 +225,17 @@ public class SignBlockEntity extends BlockEntity implements CommandSource { // C ClickEvent chatclickable = chatmodifier.getClickEvent(); if (chatclickable != null && chatclickable.getAction() == ClickEvent.Action.RUN_COMMAND) { - player.getServer().getCommands().performCommand(this.createCommandSourceStack(player), chatclickable.getValue()); + // Paper start + String command = chatclickable.getValue().startsWith("/") ? chatclickable.getValue() : "/" + chatclickable.getValue(); + if (org.spigotmc.SpigotConfig.logCommands) { + LOGGER.info("{} issued server command: {}", player.getScoreboardName(), command); + } + io.papermc.paper.event.player.PlayerSignCommandPreprocessEvent event = new io.papermc.paper.event.player.PlayerSignCommandPreprocessEvent(player.getBukkitEntity(), command, new org.bukkit.craftbukkit.util.LazyPlayerSet(player.getServer()), (org.bukkit.block.Sign) net.minecraft.server.MCUtil.toBukkitBlock(this.level, this.worldPosition).getState()); + if (!event.callEvent()) { + return false; + } + player.getServer().getCommands().performCommand(this.createCommandSourceStack(((org.bukkit.craftbukkit.entity.CraftPlayer) event.getPlayer()).getHandle()), event.getMessage()); + // Paper end } } @@ -260,8 +271,21 @@ public class SignBlockEntity extends BlockEntity implements CommandSource { // C String s = player == null ?
