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!)

    • Practically free to run, unlike the tremendously expensive Orebfuscator.
    • Most legit players won't notice, but xrayers will ragequit and move on.
  • Population Density
    • Automatically assigns new players to wilderness where they'll find other new players and plenty of space, wood, and ore.
    • Optional teleportation system which can't be abused by players to escape combat or save them from being lost.
    • Login queue to guarantee fairness when the server is full.
    • Optional reserved spots for administrators.
    • Automatically removes idle players when the server is nearly full.
    • Smart, multi-layered anti-lag feature set.

Coming Soon

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

  • Automatically extend new land claims to cover entire vertical builds (even those which extend far underground). This means claiming an already-built construction from ground level or even the roof will still claim the entire structure, assuming it's vertically continuous.
  • Update /RestoreNature to regrow trees in biomes where they're expected.

Please Vote for Grief Prevention

I've also posted Grief Prevention on the Spigot site, where plugins are ranked based on reviews. 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!

    Neat idea about the cacti. I guess the point of this plugin is not to make roller coasters but if you have to give people /containertrust to let them ride a cart they can also take it. That's what I meant by too bad it was not separated to choose to allow public ride so people can ride even if they can not place or take the carts. However I found my solution using Autocarts plugin. Leave access and /containertrust off for everyone in your admin claim and people can just magic spawn a cart with a right click on a rail and it disappears when they jump out with a shift.

    Is there any way to change the grief protection block from a chest to something else? I'm sorry if this was in the manual and I overlooked it, but I hope there is a way.

    @Disorbs: Go

    Mobs do spawn in protected areas. Except for "creative mode" worlds (see GP config), GP does nothing with spawns.

    @Bobcat00: Go

    Alright, I'll reduce the delay.

    @Coolbannana44: Go

    You have to be running an up to date version of 1.8. Please see the giant block of bold text in the changelogs, which you neglected to read when it was last on your screen. Then update your server by re-running buildtools.jar.

    @snablesnot: Go

    Placing a cart requires access trust (/accesstrust). Removing a cart might be theft (we don't know who it belongs to), so it's /containertrust. You can automatically make carts reclaimable by for example running them into a cactus, which turns them back into an item.

    I super love this plugin and it is nearly perfection. But I have stumbled onto a problem.... On admin claim with no access for all or any player you can place a cart on a rail but can not take it off. I am not sure if this is the same on player land claims. It would be great if placing and retrieving carts could be blocked or allowed separately from allowing or not allowing people to ride existing carts.

    WTF. The plugin does not prevent claimed blocks explosive damage even when it is configured to... Can I get some help here?

    How do I get it so this plugin is only for me, the owner. I want only me to be able to claim and set lands because I'm making a server hub so no one else can break blocks but I just want it for me because it's a SMP server. -Just me -Direction easy please -I'm new, REAL NEW!

    I know that GriefPreventionEx isn't working with version 1.8 but I was curious about something. I know that GPE used the codes like, "/gpemobspawn and /gpemobdamage" to prevent monsters from attacking and spawning in a claim. Is there anything out there that will work with your plugin to stop mobs from spawning in a GP claim?

  • Avatar of Bobcat00 Bobcat00 Jul 25, 2015 at 08:47 UTC - 0 likes

    Yes, it would be nice for admins to get the book and give it to others.

    EDIT: This happened on my server today - A new player joined and 16 seconds later started playing Mob Arena. So I'm guessing the GriefPrevention book was given to him while he was in the arena, and lost when he finished playing Mob Arena. A similar problem could occur if they go to my creative world (where GP is disabled). So you might want to re-think that 30 second delay.

    Op should be able to give themselves or others this fabled, GP book :-) just in case one should need to spawn such a book.
