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.

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!

    @DarthRiddle: Go

    are you a user or a server owner/admin? if you are using GP on someone else's server, they probably didn't set it up right or something like that.

    if you're the owner and having trouble understanding the plugin then I suggest you READ the messages the plugin sends you. its like this all the time on my server, so many people don't bother reading the instructions or watching the tutorial video and just spam the chat with "This St isn't working" without thinking.

    You could try disabling the anti-Spam meassures in GP, don't remember if they have a specific option to allow punctuation in Ip's or URLs but I'm pretty sure they do.

    How do I block the feature that when someone types in an ip address it removes the periods. I need this plugin to keep the periods because it is messing with the mechanics of another plugin. Please help.

    I've been having issues recently with players not being able to breed animals in claims, and intermittently, other entity spawning issues. Is this a bug with GP or could another plugin be interfering? As far as I can tell, I've checked the world's config, and any relative-sounding option is enabled, and trusts have been checked, but breeding seems to be disabled entirely. Thanks in advance for any pointers here, it's the last big issue my server is having at the moment. We're using GP build #282 from the Jenkins site, and Spigot 1308.

    running the plugin om my server, its GREAT! However a week and 1000 claims later I did manager to run into 2 small problems. ( using 1.7.2 Beta on spigot)

    1) players who have and / or griefprevention.restorenature don't have access to the respective commands, in Groupmanager atleast.

    2) the option to disallow PvP within player / admin claims keep resetting themselves to false for some reason.

    Hope I'm not just a noob who can't setup permissions :b

    I'm a teacher and started running a server for elementary students about a month ago, so this looks great. I've been trying it out on a test server and had a couple questions. 1) I have certain areas set as no build in Worldguard (areas where I've built educational stuff so it doesn't get destroyed). Will this override GP, or do I need to set them all up as admin claims? 2) I was excited about the tree topping, for some reason 10 year olds never take down the whole tree. I have it set to true, but on my test server the tops never went away on their own, or replanted. I'm using the new dev build. Am I doing something wrong?

    Thanks for the plugin, it looks like it will solve a lot of my headaches!

    Is there a way I can add a block that people cant get into on a claim because I'm running a 1.6.4 FTB server and people can get into me access terminals, Crafting terminals, Controllers, Interfaces, etc. So if someone could help me by telling me how to add a block id to stop people from accessing these items that would be great!

    Thanks, Just Blazed

    649 pages of comments is a bit daunting to sort through so I apologize if this request has been made already.

    I'd like a new trust level, /croptrust or /farmtrust.

    Something that would include container and access, but only allow placing/breaking of crops (and/or animal interactions). I'm building a public wheat farm on my server, and for it to be public I have to allow building trust to everyone or nobody can replant after they harvest. But I'd like it better if the wheat (or carrots, potatoes, etc) were the only thing they could break/place. It would allow replanting without letting anyone mess with the mechanics or the structure.

    @bratpitt: Go

    Easiest solution to fix that is using a permissions plug in. I didn't use a permissions plug in for a long time, but players not being able to place lava or water buckets got old quickly.

    PEX is pretty easy to set up as well as YAPP.

    Am not running any Permission plugin and want to change so player can use fire under sea level. Tought i only had to remove "RequiredPermissions:" and "- GriefPrevention.Lava"
