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 this public server. :) I maintain this server personally, which helps me catch bugs and spot opportunities for new features and improvements. Have fun!

    it was just a suggestion but having to keep an eye on the map and go around and manually restore nature on all of them takes alot of time. I like the rn feature and i think its better than using the towny with no wild perms. it is just something to save us time.

    ok i agree now, i was going off of your video for the restore. it seams to be having trouble in the jungle bio, half of large trees hanging in the air, doesnt seam to restore to seed, the seed doesnt show up on the f3 anymore maybe its guessing. hopefully the tree griefing thing will kick in and replant them. still think its easy to use and at this time where we dont have an rb yet its still working :)

    @psyduck751: Go

    None of the commands work from the console. Log in to use them.

    @gigantictragedy: Go

    Yikes... I think a map wide restore nature sounds dangerous. I won't add that. Do you really have a big problem with ruins, or are you just anticipating one? In my experience, players almost never abandon their builds. The only ruins I get are ruined dirt huts from new players who don't stick around and whose claims are automatically cleaned up.

    @Memorex39: Go

    When there's an overlap, you should see the conflicting claim highlighted in lava and netherrack. Was it not the case for you? I've intentionally disabled /deleteallclaims for administrative claims because of the potential for bad stuff to happen (like when you trust that one guy and give him permission, then he runs one command to wreck the whole place).

    On the confusion regarding creating and resizing claims, sorry, I don't know how to make it any easier, maybe you could give some specific suggestions? I tell my players to watch the video. So far, you're the only commenter to complain that managing claims is too difficult.

    I don't want to automatically shrink claims until they fit, because I don't want players to mistakenly think that what they tried to claim was correctly claimed when it wasn't. Better to tell them there's a problem and let them figure out what to do about it than to automatically protect less than they wanted, I think.

    How do I do a /deleteallclaims administrator ?  Of course my question/example does not work.

    Took me a bit to find an "overlapping claim" when doing an administrative area.  Was pretty frustrating.

    Even if the administrative area was overlapping, why wouldn't it just resize?  I don't know but was pretty ambiguous and confusing for something that should have been so simple.

    The simple text (paraphrased), "...both points made now create your claim..." is frustrating and pointless imho, if you have both points shouldn't it be created automatically?

    I like the simplicity of the idea, but I am concerned that my young users won't understand how to expand, since I had so much trouble.

    hi i just started using grief prevention on my small server. i was wondering if there could be a map wide restore nature command, or in the config set to do a map wide restore nature command settable for 2weeks or a month. it would save admins from running around doing it. say if someone unclaims an area and moves it leaves ruins that will need to be cleaned up. but if theres a map wide command or it does it threw the config it would save admins time. not sure if its possible. maybe add an enable and disable in the config for those that dont want to use it. thanks i like your mod

    I installed this plugin on my server and it works just fine...however ...when I need to use a command which requires either an amount or the name of a player the console does acknowledge it and repeats the command ...

    ex: deleteallclaims playernamehere becomes : deleteallciams <player> I don't know what to do...I added <> to the playername but nothing...please help... I just installed it 5 min ago ...I know my question noobish but cmon :)

    Ahhhh, very nice. Problem solved ;-) thx :-)

  • Avatar of bigscary bigscary Mar 11, 2012 at 05:33 UTC - 0 likes

    @seriosbrad: Go

    Yep, I understand. After the videos were made, I fixed it so that /RestoreNature wouldn't work when players are in the restoration area, because players can be suffocated. So now you have to stand outside the area, but you can use the shovel from a distance so it's easy to manage.

    @Tux2: Go

    I'm using the claim block coordinate as a reference. That doesn't work for you? It is a unique identifier, but it might change over time.

    @Memorex39: Go

    You can run both, but I suggest you either disable GP's claims, or disable PS's claim blocks (while keeping the trampoline blocks and other goodies). If you keep TWO ways for players to claim an area, then they'll be confused and griefers may find creative ways to annoy.

    @briankdk: Go

    Allowing players to use lava just anywhere on the surface is a bad idea. Griefers can make a huge mess very quickly, which can be very difficult to clean up - if it's right next to a claim, /RestoreNature won't work, and lava doesn't always go away when you pick up the source block. Having said all that, if you REALLY want to let all players place lava wherever, use a permissions plugin to give all players the "griefprevention.lava" permission.

    @Tutimane: Go

    Thanks, I'll put that documentation update on the to-do list.

    @Galexrt: Go

    Yes, you can disable the theft protection while keeping the block build/break protection on.

    @Tulonsae: Go

    I will release when it's stable. Too many new features and undocumented code lines right now.

    @briankdk: Go

    How are they destroying buildings with axes? No claims? Anyway if you want lava back on for everybody, assign "griefprevention.lava" permission to all players. Using a permissions plugin, you can do that very quickly and conveniently.

    @briankdk: Go

    Put an admin claim around the railroad with /adminclaims. You can't accomplish that goal with a standard private claim.
