From 3888b08f6d406ae45e3b9fe308c48ba8631fea53 Mon Sep 17 00:00:00 2001 From: snowleo Date: Wed, 30 Nov 2011 20:48:42 +0100 Subject: If Essentials core fails to read one of the configs now, it will disable itself. If other modules detect that Essentials is not enabled, they will be disabled too. EssentialsProtect will go into emergency mode, canceling all events that could hurt your world. Fix the file and either restart or reload the server. --- .../essentials/protect/EmergencyBlockListener.java | 36 ++++++++++++++++++++++ .../protect/EmergencyEntityListener.java | 22 +++++++++++++ .../protect/EmergencyPlayerListener.java | 16 ++++++++++ .../essentials/protect/EssentialsProtect.java | 29 +++++++++++++++-- 4 files changed, 100 insertions(+), 3 deletions(-) create mode 100644 EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyBlockListener.java create mode 100644 EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyEntityListener.java create mode 100644 EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyPlayerListener.java (limited to 'EssentialsProtect/src/com/earth2me/essentials/protect') diff --git a/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyBlockListener.java b/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyBlockListener.java new file mode 100644 index 000000000..479d2eda6 --- /dev/null +++ b/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyBlockListener.java @@ -0,0 +1,36 @@ +package com.earth2me.essentials.protect; + +import org.bukkit.event.block.BlockBreakEvent; +import org.bukkit.event.block.BlockBurnEvent; +import org.bukkit.event.block.BlockFromToEvent; +import org.bukkit.event.block.BlockIgniteEvent; +import org.bukkit.event.block.BlockListener; + + +public class EmergencyBlockListener extends BlockListener +{ + + @Override + public void onBlockBurn(final BlockBurnEvent event) + { + event.setCancelled(true); + } + + @Override + public void onBlockIgnite(final BlockIgniteEvent event) + { + event.setCancelled(true); + } + + @Override + public void onBlockFromTo(final BlockFromToEvent event) + { + event.setCancelled(true); + } + + @Override + public void onBlockBreak(final BlockBreakEvent event) + { + event.setCancelled(true); + } +} diff --git a/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyEntityListener.java b/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyEntityListener.java new file mode 100644 index 000000000..a220f07d5 --- /dev/null +++ b/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyEntityListener.java @@ -0,0 +1,22 @@ +package com.earth2me.essentials.protect; + +import org.bukkit.event.entity.EntityDamageEvent; +import org.bukkit.event.entity.EntityExplodeEvent; +import org.bukkit.event.entity.EntityListener; + + +public class EmergencyEntityListener extends EntityListener +{ + + @Override + public void onEntityExplode(final EntityExplodeEvent event) + { + event.setCancelled(true); + } + + @Override + public void onEntityDamage(final EntityDamageEvent event) + { + event.setCancelled(true); + } +} diff --git a/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyPlayerListener.java b/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyPlayerListener.java new file mode 100644 index 000000000..e92325946 --- /dev/null +++ b/EssentialsProtect/src/com/earth2me/essentials/protect/EmergencyPlayerListener.java @@ -0,0 +1,16 @@ +package com.earth2me.essentials.protect; + +import org.bukkit.event.player.PlayerJoinEvent; +import org.bukkit.event.player.PlayerListener; + + +public class EmergencyPlayerListener extends PlayerListener +{ + + @Override + public void onPlayerJoin(PlayerJoinEvent event) + { + event.getPlayer().sendMessage("Essentials Protect is in emergency mode.
