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.

Official Servers (Try it for yourself!)

You can experience this plugin for yourself (as a player) by joining any of these public servers. :) We maintain these servers personally, which helps us catch bugs and spot opportunities for new features and improvements. Have fun!

Coming Soon

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

  • 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.

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!

    Player Invincibility, players can use /kits to obtain items, Or go to a shop and buy items from a sign, Items are also spawned via autorank via /give if they rank up and /give via buycraft.

    There is no error when creating a new sub-claim in the console, they have just vanished after a server reboot.

    @erik1988: Go

    Don't give it to your players - it's an administrative command that will change the owner of ANY land claim, even of those land claims you don't own yourself. Even if it were restricted to only the claims you own, it would still be a bad idea to give to players because by giving claims away to others, players could cooperate to claim an unlimited amount of land.

    @danf21: Go

    Either upgrade your server to 1.8, or use a version of GriefPrevention made for your server version.

    @switorik: Go

    Thanks, I'll investigate both. :)

    How to fix this Error?

    @bigscary: Go

    How does this "transferclaim" cmd work? (missing from the docs). Is this something that is safe to give to players? My interpritation is that you can send players your claimblock, is this correct?

  • Avatar of switorik switorik Feb 25, 2015 at 23:01 UTC - 0 likes

    Running the latest griefprevention and spigot builds I think I have come across two bugs. I still have the bug where zombeis can not attack villagers in someones claim and also players with permission trust in a subclaim can not trust other people to that sub claim (unless they have that trust level on the parent claim).

  • Avatar of bigscary bigscary Feb 25, 2015 at 21:35 UTC - 0 likes

    Hey everyone, I updated the docs. :) If you notice anything missing, please tell me. Thanks! Sorry I took so long to get around to it.

    @zedadiaswick: Go

    In modern versions, it only changes the recipient list. It used to do the other thing.

    @daycraft: Go

    You say your players can use slash commands, but not right click? I don't believe it. Anyway, they should watch the demonstration video which actually shows them how to do everything, and which is linked to them directly in the game. I don't see how it could possibly be made any easier - maybe your players would be interested in an in-home tutoring service for land claims?

    @MoldySpore: Go

    You shouldn't expect any issues running GP on an old map. GP no longer removes water when claims are removed, except for in creative mode worlds.

    About collecting the border items, I think either you're thinking of another plugin, or maybe you grabbed a very bad version from when I wasn't working on the project. This comment is the only time I've ever heard of anyone being able to collect the border blocks, so I'm sure you're safe there. Also, they do disappear automatically after an amount of time now.

    @groovyloopylou: Go

    You can use a negative number to remove blocks with /acb. Note that if a player actually has land claims which add up to more than his current block total, his block total will automatically increase so that he doesn't have less than 0 total blocks. So you may have to actually delete some land claims in that case.

    @MrsWaterhouse: Go

    I think you should ask the MCProHost staff for instructions on how to install plugins on their servers. On every server I've ever used, just uploading GriefPrevention.jar to the "plugins" folder worked great.

    /adjustbonusclaimblocks <player> -600

    just use negative numbers, rather than positive :)

    I am having real trouble adding this to my MCProHost server. Any suggestions please? I have changed my server type to Spigot version 1.8 - Downloaded the GP.Jar - renamed it to custom.jar Still nothing. Also I have not idea where to look for all the custom options? Please help Many thanks

    @groovyloopylou: with a minus /acb player -10

  • Avatar of groovyloopylou groovyloopylou Feb 24, 2015 at 21:18 UTC - 0 likes

    Quick Q, how do you remove bonus blocks from a player? /acb just keeps adding and adding them on...
