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.

    Are we ever gonna see an updated version of Grief Prevention?

    Seems like it's just been dev builds for quite some time now. After last times horrid bug that deleted claims I'd rather hold off on the buggy dev builds till a stable one is released. As it stands my server is still running on the 7.8-beta-b213 and claims in 'The End' simply do not work. Upon the daily restart they just vanish. No idea why..

    Anyway is there any sort of ETA?

    Now i just wonder, how many dev builds do i have to step back, to get rid of the error [00:05:03 INFO]: [GriefPrevention] Unable to save data for player Fungreenfox. Details: [00:05:03 WARN]: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''name','lastlogin','accruedblocks','bonusblocks','clearonjoin') VALUES ('Fungre' at line 1

    @pr4xt3roy: Go

    /giveclaim requires owners right the property. So he/she can only give own claim away.

    /transferclaim is an admin tool, can transfer any claim.

    This is weird, it seems to block only 1 thing from everyone including me with all permissions, whenever I post my own website it is blocked for "spam" yet I can post ANY other site.

    Quick question...

    If an admin can transfer anyone's claim using /giveclaim, then what is the purpose of /transferclaim ?

    the way I understand it, /giveclaim would be for users and /trsnsferclaim for admins... but they seem to do exacly the same no?

    The only difference I see is that using /transferclaim without any parameter will transfer a claim into an admin claim. But /giveclaim could do that too (when you have proper permissino) and you would have one less command to worry about.

    Despite what is set in the config, players on my server are still able to PvP inside any GriefPrevention claims. Things like breaking blocks and even potion splash is still protected against in the claim, however. If a WorldGuard region is set to no pvp, they can't PvP there, so I'm fairly certain it has to do with the plugin... has anyone else had this issue, or is there something I'm not setting up correctly?

    Does this work with votecatcher

    OK there are a few things unclear to me:

    1. What is entity cleanup task?

    2. If I set "AllClaimDays: 40" and disable ClaimCleanup like so: ClaimCleanup: Interval: 300 Quantity: 5 MaximumSize: 25 MaxInvestmentScore: 100 Enabled: false Will claims still get removed after 40 days of inactivity?

    3. If a player creates his first claim with a chest and than resizes it. Will this claim still be considered as chestclaim (that gets removed after 7 days) or not?

    4. How exactly does this claim removing work? I just want to know about allclaimdays function. When does it check if claims are not used over 40 days? Because I do sometimes find claims that belong to player who didn't play for more than 40 days.

    5. Does a player have to build anything on a claim so it doesn't get automatically removed or is it enough for him to just log on the server?

    6. What if a claim belongs to player A and player B has a trust to build on it. Will the claim get removed if player A doesn't log on in 40 days even if player B is building things on player A's claim?

    I am currently using b213 and there are so many random bugs and claims that should be automatically unclaimed. I am also setting things up for a new server and am trying to use b277. Should I start with this build or can I expect problems in long term? This plugin was awesome till 7.8. Now there are just so many bugs an I have a really hard time using it. Please devote some more time fixing bugs. And ty for all the work you do :D
