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.

    Hello on my server I made a new Multiverse world and cant make any claims in it please help me!!!!!!

    If I could do polygon selection, I would be so happy. The same way we trigger /adminclaims before placing a claim, we could trigger /polyclaim.

    Honestly, just tying it into WorldEdit would be fantastic. All we would need is a /create claim command or something along those lines.

    Anyone run into an issue with tamed horses disappearing from someones claim? Ours keep vanishing and not sure what else could be doing it. Seemed to start after installing GP and not sure if I missed a setting. Could be coincidence.

    Um, I love this plugin, But wouldn't it be cooler if u cud have the option of naming your claim, so when ppl walk into it, the name appears of claim they entered. Like a admin claims a city or town and names it "spawn town" and player enters it, it says "entering spawn town" I don't want to have to get towny in order to do this.

    I see a lot of server admins, myself included, run WorldGuard for admin claims and have GriefPrevention for player claims.

    The problem with this is that GriefPrevention doesn't check if you're inside of a WG claim already. It would be fantastic to make this plugin compatable with WG so that if you add a custom flag (say, grief_prevetion deny) to a WG area, GP would respect that.

    I love the ease of use of GP, but it's not robust enough for admin purposes. And I love the robustness of WG, but it's not user friendly. Both plugins do an excellent job, but it would be great if they played nicer together.

    How would I make it so only admins can place lava and water anywhere?

    So, I just thought of an idea for my server after watching the GP videos. Does anyone know if this would work?

    Create a marketplace using adminclaims and then subdivide it and create small shops, sell someone the rights to use ContainerTrust. Would people then be able to place signs and work with ChestShop? Or could I pre-place signs and then they could edit the writing? Hmm.

    What about an idea for future development to Place signs in a subdivision and have it connect to an Economy plugin and use that sign to display and sell that subdivision. Also adding to that, what about identifying specific rights on that sign for that subdivision?

    Does anyone have a world config that works well with pixelmon? I am using gp 7.8 and pixelmon don't take damage in claimed regions

    @Max633: Go

    Try giving yourself /ignoreclaims. It usually fixes things, if not then this is a bug and should be reported in the tickets section.
