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.

    @fungreenfox: Go

    Should be fixed now with #279.

    @pr4xt3roy: Go

    /giveclaim has a separate permission and is primarily for players to give one of their claims to another player. (It doesn't give or take claim blocks). Players can use it without administrator permissions, but without admin it only works on their claims.

    /transferclaim is primarily for switching a claim from a admin to a player claim. (and vice versa) by those with the proper permissions/ops. transferclaim was used previously to give claims to other players, but it required an admin and two commands- one to make the player claim an admin claim, and one to make it a player claim owned by the new owner. With /giveclaim it will not require an admin to perform the task where one player wants to give ownership of their claim to another.

    I had the same problem, because some settings get automatically changed in config. Just change all the config files to read-only.

    At my server, players can't event store their claims into the mysql data anymore. I have to find a solution.

    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.
