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.

Coming Soon

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

  • More performance tweaks.
  • Update /RestoreNature for new block types in 1.8.
  • Update /RestoreNature to handle water better.
  • Update /RestoreNature to regrow trees.
  • Fix killer bunnies not being damageable in other players' land claims (because Bukkit labels them "animals", not "monsters").
  • Add an abridged, easy-to-read chat log which auto-deletes its old data.
  • A /ignore command for players.
  • A /separate command to force two players to ignore each other.

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!

    @cyris69: Go

    I don't think that has anything to do with GP, since GP isn't a mod. It's a plugin (bukkit platform, not forge). But, maybe someone who runs a server more like yours is listening and will recognize your problem :) Good luck!

    I need some help from teh Devs

    I run this tekkit pack (i know not bukkit) but you have an area I can list mods in teh configs but not sure how to go about what I'm getting currently. Here is what I get when logging into my local server Imgure screenshot

    This is the pack contents:

    It has 200 mods so conflicts I can assume or a permissions issue?

    EDIT: DO NOT use this version. If you downloaded it, revert back to 11.1. I'm very sorry guys, but I screwed up when compiling it and the land claims don't work. :( I've made the download no longer available, and I'm working on a fix.

    11.2 Updates

    • Faster almost everything.
    • Faster visualizations.
    • Fixed PvP immune players being able to attack pets.
    • /ClaimExplosions and the config option to enable explosion damage in all claims both override the sea level protections now. Exception: Still absolutely no explosion damage in creative mode worlds, where griefers have unlimited TNT.

    Please take a few moments to vote for Grief Prevention. :) Thanks for your support!

    Hi! Do you have an API, or is there any way I could tie into your plugin to check for for a player's ability to build in an area?


  • Avatar of abstractmadness abstractmadness Mar 28, 2015 at 19:27 UTC - 0 likes

    Is there a way to block commands inside a claim? For example I want to block the /sethome command to anyone who isn't trusted, I found a [BlockedSlashCommands: /home; /vanish; /spawn] under the PvP area of the configuration, can this line be copied over to another area to get the job done or is this something that would have to be programmed in by you guys?

    Great plugin btw, use it 24/7 and recommend it to all my friends with servers. Keep up the good work!

    @CrypticCabub: Go

    If you are talking about them getting claimblocks every weekend (or which ever amount of set time you want) instead of the option to give claimblocks as time goes on, You could use another plugin that does scheduled commands or even just a command block depending on what you are looking for.

    I use PhatLoots and I know you can set it up with a command that allows a "loot chance" For example I have a Daily Chest, Weekly Chest and First Time Chest. Within the First time Chest I have a custom made golden shovel that they can use to claim, with the instructions written down on it as well as a command that gives them 10k claim blocks, this chest can be looted once a month

    @pr4xt3roy Yes it was my that requested a log, since there are so many bugs, we need to have a history of what players have done to try and figure out what an issue is, its impossible without a history, This wouldn't just benefit admins, it would benefit development as people would be able to record issues much easier.

    I have PM'd you an issue still with /sellclaimblocks & bonusblocks, Selling does now properly deduct from the right column, but somewhere along the lines there is some bad maths still, I have a player thats golden shovel is reporting 16k blocks but /sellclaimblocks is showing 60,000! Again, players can exploit this for incredible amounts of money.

    It's getting pretty annoying and it doesn't go away until relog :/

    It appears that /trapped is broken. :/

    sorry i meant mods as in moderators. I just want it so normal people can't teleport, or drop items during pvp, but moderators can do whatever they want when classed as 'in pvp'
