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!

    • 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.

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. I've even added some new anti-grief features.

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. :)

Coming Soon

These are my top priorities right now. It's not a complete list of everything I plan to do. :)

  • Allow owners to interact with their pets even when in other players' land claims.
  • Protect tamed animals everywhere in non-PvP worlds, with the exception of those left in other players' land claims after the animal's owner logs out.
  • Stop negative splash potion status effects from applying to players who should be protected from PvP. (Damage is already blocked)
  • Look into killer bunnies not being damageable in other players' land claims.
  • Improve boot speed for flat file mode.
  • Prevent nether portal traps.
  • Prevent placing a nether portal in a land claim by building a portal in another world.
  • Fix sand/gravel cannons.
  • Require players to move at least a block after logging in before allowing them to chat (anti-bot strategy).
  • Update /RestoreNature for new block types in 1.8.
  • Update /RestoreNature to handle water better.
  • Update /RestoreNature to regrow trees.
  • Prevent claiming land inside a world guard region unless the claimant has permission to build in the region.

I'm aware there are issues specific to modded (not CraftBukkit or Spigot) servers. I do plan to address those, but I'm waiting for Cauldron to update to 1.8.

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!

    @Smac3223: Go

    Seems like it's just been dev builds for quite some time now. After last times horrid bug that deleted claims I'd rather hold off on the buggy dev builds till a stable one is released. As it stands my server is still running on the 7.8-beta-b213 and claims in 'The End' simply do not work. Upon the daily restart they just vanish. No idea why..

    I could tag any version as stable if I wanted to. There wouldn't be anything particularly "stable" about it. There are no unit tests so it can't be based of passing them, and Even spending an entire evening messing with it on my test server I can barely get any code coverage. Even tagging a build as beta brings with it more assumptions of stability than feel I am able to responsibly guarantee.

    Even so, I was going to try to get another beta available here soon. providing build 279 as a beta would be no less arbitrary than earlier builds.

    That said, the main concern would be what happens with the changes to PlayerData names, particularly in existing data that would be brought forward. It worked when I tried earlier with 7.7, but I "only" have three accounts (one of which I recently bought solely for testing GP with all-lowercase users).

    Even with a stable build/upgrade I think it will be prudent to replicate any database information GP is using and/or flat file information, to avoid a worst-case scenario that some unlucky individuals experienced from some of the dev builds.

    At least now that you've mentioned the version you have I can stop trying to reproduce your issue. That said I'm not sure why you would be booted to the overworld when you log back in in any case.

    @fungreenfox: Go

    Should be fixed now with #279.

    @pr4xt3roy: Go

    /giveclaim has a separate permission and is primarily for players to give one of their claims to another player. (It doesn't give or take claim blocks). Players can use it without administrator permissions, but without admin it only works on their claims.

    /transferclaim is primarily for switching a claim from a admin to a player claim. (and vice versa) by those with the proper permissions/ops. transferclaim was used previously to give claims to other players, but it required an admin and two commands- one to make the player claim an admin claim, and one to make it a player claim owned by the new owner. With /giveclaim it will not require an admin to perform the task where one player wants to give ownership of their claim to another.

    I had the same problem, because some settings get automatically changed in config. Just change all the config files to read-only.

    At my server, players can't event store their claims into the mysql data anymore. I have to find a solution.

    Are we ever gonna see an updated version of Grief Prevention?

    Seems like it's just been dev builds for quite some time now. After last times horrid bug that deleted claims I'd rather hold off on the buggy dev builds till a stable one is released. As it stands my server is still running on the 7.8-beta-b213 and claims in 'The End' simply do not work. Upon the daily restart they just vanish. No idea why..

    Anyway is there any sort of ETA?

    Now i just wonder, how many dev builds do i have to step back, to get rid of the error [00:05:03 INFO]: [GriefPrevention] Unable to save data for player Fungreenfox. Details: [00:05:03 WARN]: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''name','lastlogin','accruedblocks','bonusblocks','clearonjoin') VALUES ('Fungre' at line 1

    @pr4xt3roy: Go

    /giveclaim requires owners right the property. So he/she can only give own claim away.

    /transferclaim is an admin tool, can transfer any claim.
