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.

      • No database.

    @Qballl: Go

    Yes, that's right. Unless you count code comments, which you can see on github.

    @Kira_Kun: Go

    When it reverts back to defaults, that means you made a yaml syntax error. Use a yaml editor like notepadplusplus which will highlight errors when you make them, and always back up your file before you restart the server.

    @natureclub2016server: Go

    Yes, latest versions are for 1.9.2.

    Is greif prevention for 1.9.2?

  • Avatar of Kira_Kun Kira_Kun May 03, 2016 at 10:48 UTC - 0 likes

    i noticed that there is a messages.yml in the config folder which led me to think i could localize the language as appropriate but after translating the texts and starting the server i noticed that it reverted back to english.

    can someone tell me how i can go about localizing the language if editing messages.yml simply doesnt work?

    @Qballl: Go

    There's some but it's outdated. Just take a look at the source code if you'd like to know what something does, he has lots of comments explaining what does what.

    This account is so old that I don't even use that username anymore.
    I now go by "robomwm"

    @VittoxWL: Go

    I'm not sure I understand your question. If there's no PvP anywhere, that might be because you have PvP disabled in your vanilla file. If you mean you get a grief prevention message in land claims saying you can't pvp here (but you can outside of land claims), then there's an option in the config file to allow pvp in certain types of land claims, or all of them if that's what you want.

    @Qballl: Go

    Yep, just set up a reference and poke around. There are no up to date developer api docs.

    @pooroo: Go

    It's tough to make it work when you're just testing it. While you're offline, delete your player data file (in the world folder you logged out in), then deop yourself and log back in, and wait 30 seconds.

    @foxi69: Go

    It's on for creative mode worlds always. There's a config option to make it work in survival worlds, which defaults to off.

    @Yupie123: Go

    I deleted the page because it was terribly outdated. For now you'll just have to use the code comments on github. Sorry! I've got a todo list of tweaks and minor bug fixes, and then after that's done I can come back to API docs - but I have maybe 1 hour of free time per 2 days now.

    I was wondering where I could find the API documentation? I'm not able to access this page anymore:

    @bigscary: Go
