Grief Prevention


AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava dumping, chat trolling, advertising and more, so you don't have to undo any damage after the fact. It even teaches players how to use it so you don't have to! 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 creative building.

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.

    I created a new world using CommandHelper and TerrainControl plugins (not Multiverse) and added it to the bukkit.yml worlds list too. I stopped the server and modified plugins/GriefPreventionData/config.yml to add this new world to the list of worlds.

          world_the_end: Disabled
          world_nether: Disabled
          world: Survival
          my_new_shiny_world: Disabled

    When I restart the server, I can still claim in that world and what I added to plugins/GriefPreventionData/config.yml is gone!

    Is there something else I need to do?

    The way CommandHelper works is that the world is configured 1 seconds after the server starts. So there is a moment where there are no such world... Could it be that the GriefPrevention plugin check for worlds before it gets "defined" and sees it does not exists (yet) and remove it from the config?


    PS: Your documentation ( says that the configuration variable is claims.worlds when it looks like its more Claims.Mode instead, right? Does the documentation needs to be updated or did I update the wrong config variable?

    @opentexon Your plugin looks very nice! :)

    I am on Spigot 1.8.8 R3, I also use Hardcore 3.6.5.

    So far it doesn't work correctly. i get the messages that a claim has been set but players can still do whatever they want in your area.

    Update 13.1 is here! :)

    @Disorbs: Go

    What do you mean it isn't working? Try it on yourself to be sure. If it's still not, what version of GP are you on?

    @unclemark: Go

    The minechat issue was already fixed. If a player has played on your server before, he won't have a problem mine chatting. If all he's ever done is chat, then yes there is a problem but I don't see a fix for that rare case short of disabling the anti-bot feature altogether, which is not a good trade-off. If you do as PCtech suggests and disable this feature, beware the bots.

    @unclemark: Go

    You can use /acb to give players claim blocks. Maybe you can somehow integrate that with your shop signs? Not sure how, steps would depend on your specific shops plugin.

    @BlockBert: Go

    The survival requiring claims mode (see setup/config) prevents players from changing the world unless they first place a land claim. It requires some thinking though to work well, so you'll have to think over the design of your server if you decide to turn on that mode.

    As for enter/exit messages, those aren't in the base plugin because they're not anti-grief, but you can add them with GriefPrevention Flags.

    @MisterMewbacca: Go

    Change your claims mode (see config file) for that world to survival. However if your players in that world are in creative mode, you will have serious griefing problems so consider carefully. There's more info/advice on this in the setup/config page.

    @missemilia06: Go

    That's in the command/permissions reference page linked above.

    @BlockBert: Go

    This would require registering a listener for the onPlayerMovement (or whatever it's named) event, which is something I wouldn't want to see in here mainly for performance reasons. However, this is possible to do in an add-on. PM me if you'd be interested in such a thing (I don't subscribe to comments here).

    @unclemark: Go

    If they haven't even played on your server yet (get wood achievement), then yes, they will be prevented from chatting. If you really want players to use Minechat without playing on your server, use spigot.yml to force the achievement on them (I've tested this before and yes it works).

    What version of GriefPrevention are you running? Also make sure you have the correct Survival/Creative mode defined in the GP config.

    Server: - Survival/PVP, 7 Mob Arenas, Creative World

    The admin of our server is able to query with a stick that person who currently claims that spot and it also tells him that particular persons last login as well. I couldn't find a permission in the list to allow others to do this as well. We want to be able to view that persons last login as well.

    I can't break or build anything outside my plot. Every time i try i receive the message "You can't build here unless you claim some land first. To override use use /ignore claims. click for land claim help:". I've tried looking in the config files and i can't find a way to fix it . I want everyones plots to be protected and every other area to unprotected where people can build and break blocks outside of.

    Hey, I previously used MyChunk, but as it became abandoned, I am looking for a new plugin. I really liked the easy-to-use features such as notifications when you entered someone's chunks or the ability to resell claimed land. And the most important feature I used was to protect all unclaimed land. So no one could grief in the wilderness without buying the land. Could you add some of those features? Just for suggestion: You could make them as optionally so everyone can decide whether he needs this feature or not. That would be great! :-)

    Greetz, Blockbert
