Grief Prevention

Grief Prevention

AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava 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.

The Manual

More Great Plugins!

    • Limits how quickly players can mine valuables, based on their play time / values mined ratio.
    • Keeps your valuables in the ground, so non-cheating players can find them (unlike ore loggers).
    • Practically free to run, unlike the tremendously expensive Orebfuscator.
    • Most legit players won't notice, but xrayers will ragequit and move on.
  • Population Density
    • Automatically assigns new players to wilderness where they'll find other new players and plenty of space, wood, and ore.
    • Optional teleportation system which can't be abused by players to escape combat or save them from being lost.
    • Login queue to guarantee fairness when the server is full.
    • Optional reserved spots for administrators.
    • Automatically removes idle players when the server is nearly full.
  • EnderHoppers
    • Allows the use of Hoppers with EnderChests inside a Claim
    • Items are taken from and added to the EnderChest inventory of the Claim owner
    • Supports The Better Ender Chest Plugin

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 continued the project from there as if I hadn't left in the first place. So far, I've added UUID support, greatly improved performance during play time and boot time, blocked new grief strategies made possible by changes to the game since I last worked on the project, cleaned up the config files, and tweaked several features for much improved player and administrator experiences.

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, I will continue working on this project as I always have. No other project I've ever worked on in my career as a software engineer compares to GriefPrevention's mix of fun, challenge, and importance to the community.

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!). In any case, please back up before you take on this major update. If you have any problems, restore your data from backup, use the older version of GP which was working for you for now, and get your logs to me so I can investigate. :)

Please Vote for Grief Prevention

I've just posted Grief Prevention on the Spigot site. If you love GP, please take a couple of minutes to give GP your rating and leave a short review. Better rating and positive reviews will help server owners who look for plugins on the Spigot site make the safe choice (GP) instead of downloading something sketchy or incomplete. :) Thanks so much for all your support!

    @Disorbs

    As of right now the only way to prevent claiming in a world guard region is to claim the region with an admin claim. At some point in time world guard MAY be supported but not right now.

    Can the Spam feature blocks sending message if the player hasn't moved at all?

    Just stepping in to make sure you guys are still with us =)

    We're stuck in Bukkit 1.7 like everyone else. Fingers crossed any alternatives will turn up soon. Our server is still quite active and liked. Grief Prevention is pretty much the plugin that determine which platform we'll end up with.

    I'm guessing it's a bit far-fetched to hope for a version that works with vanilla servers?

    If nothing else it looks like Spigot has something in the works.

    How could I make it so every chest placed is automatically protected?

    @Bobcat00: Go

    The permission is definitely spelt correctly. They have access to all the admin claim stuff just not /transferclaim. I'm using verion 8.7.1, I probably should update.

    @Turbotailz: Go

    griefprevention.adminclaims should work for /transferclaim. What version are you using? Also check that you spelled the permission properly.

    @Luficer: Go

    I want my Moderators to have access to /transferclaims, I have given them the adminclaims permission as well as adjustclaimblocks, which both seem to work fine for their intended purposes, just not /transferclaim.

    It's not a huge deal because obviously I can just transfer the claims myself, but it would be nice to have my Moderators do this on my behalf.
