Grief Prevention

Grief Prevention

AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava, treetopping and more, so you don't have to undo any damage after the fact. No configuration or database required! Stop responding to grief and prevent it instead. Grief Prevention will solve your grief problems without requiring you to manage a roster of trained administrators, juggle 10 different anti-grief plugins, take away cool standard game features, publish a training manual / tutorial for players, or add explanatory signs to your world. You can also choose to integrate PvP elements into build design to finally get a PvP experience befitting a sandbox game about creativity.

Grief Prevention stops grief before it starts automatically without any effort from administrators, and with very little (self service) effort from players. Solve all your grief problems with a single download, no database, and no configuration step.

Project Status and Future

From BigScary: I've re-joined the project. Yes, I know many of you had a very bad experience with the beta builds, there were many bugs. We've rolled-back the buggy features which were added after I left the project, and then I added necessary anti-grief features for new game elements (leashes, hoppers, mounts). I've also added UUID support, and the current focus is improving performance.

Because all of the Bukkit staff have simultaneously quit the project, it's extremely unlikely that Bukkit will ever be updated to support Minecraft 1.8 or later servers. Also, there's a legal issue which resulted in all craftbukkit builds being removed from the internet in general. The law is slow, so that makes future bukkit versions even less likely.

Due to these circumstances, my current plan is to wait for a new mod platform to emerge (spongepowered.org is looking promising), then build a new grief prevention plugin for that new platform. Until then, Tux and I will perform the minimum maintenance needed for this project, which includes fixes for grief (including UUID support), bug report investigations, and bug fixes. Depending on how quickly the sponge platform gets ready to go, there may be time for me to slip in some minor tweaks here and there as well. There will be no major feature adds (like new config options or per world configs).

How to Upgrade to 8.0+ Builds

Starting with GriefPrevention 8.0.3, you can keep any claims and player data that was created by the broken "beta" builds. You just have to customize your config file again (a new config.yml will be generated in a folder named "GriefPreventionData").

Starting with GriefPrevention 8.1 which supports UUID (player name changes), GriefPrevention will do a one-time data update during boot. This can take a very long time - up to 1 second for each player who has ever played on your server. This is because GP has to contact Mojang via the interwebs to get the correct UUID for each player. At this time, it seems this process works well for offline mode and online mode servers, but there are mixed reviews for the hybrid "Bungee Cord" configuration (try it, but back-up first!). I'm not sure how GP can make it work for Bungee configs 100% correctly - if anyone has specific information on how solve this problem, please share it.

    Seems to be pretty effective according to the comments....

    maby these 2 mods could "melt" together - in the near future ?:-)

    Hi, I'm currently running version 2.2 on my server (which is running craftbukkit 1.2.3).

    Currently on 2.2 we receive the 'PlayerEventHandler.onItemHeldChange' error, so we tried upgrading to 2.4 - but upon starting the server we get the following errors:

    2012-03-12 03:05:28 [INFO] GriefPrevention: Unable to load data for player "antchris11": Expected four distinct parts to the location string. 2012-03-12 03:05:28 [INFO] GriefPrevention: Unable to load data for player "brynrules29": Expected four distinct parts to the location string. 2012-03-12 03:05:28 [INFO] GriefPrevention: Unable to load data for player "bubblegumface": Expected four distinct parts to the location string. 2012-03-12 03:05:28 [INFO] GriefPrevention: Unable to load data for player "G3nesys": Expected four distinct parts to the location string.

    These continue for several hundred lines.

    Any ideas on what's going on, I understand this is a dev build - but these caused an issue resetting the number of claim blocks players had?

    @cvxx7q: Go

    so you can select your protection like a cuboid?
    or when you select the lowest point everything on the top is protected?

     Mine with bros @ play.broscraft.com not with hoes.

    @domingo15: Go

    if you wish to protect ur dungeon claim the bottom most points
    so knock a block or two out of each corner so u can claim the whole room

    if its not a room however then u will get some difficulty (finding where shit is XD), the config has a depth option, use something like 32 and claim at the base of ur castle

    all it does is call a chunk regen, it is up to oreobfuscator to catch this, u can test if it works easily tho, loopback server copy? (if possible)

    @Jayyx2: Go

    yeah typical asswipe tactic

    @briankdk: Go

    he fail :P

  • Avatar of Jayyx2 Jayyx2 Mar 11, 2012 at 22:27 UTC - 0 likes

    "you can't dump lava here because this claim was recently modified" occurred when a player was attempting to place water inside their own claim after extending it.

    @briankdk: Go

    They were using a proxy list. It was annoying. Also, it's better to ban the accounts because they have a finite number of accounts they could use. The list of proxy IPs it too damn high!

    @bigscary: Go

    I've watch all the videos and this seems to be promising but i just want to know when you claim the blocks how would you know the height and depth of the protection?

    Like, if there is a castle 40 blocks high and have a dungeon underground about 20 blocks down, how would i protect that?

    EDIT: this seems to be very easy to use, one more thing. Is the chunk regeneration or called "restorenature" anti X-ray safe like OreToClientObfuscation or Orebfuscator when regenerating the chunk?
