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.

    Hi there. I'm new to Minecraft - trying to get up to speed so I can join my son. Just got a hosted server not long ago. Installed Grief Prevention. I love how it works. It's already prevented some serious squabbles between my son and his friends.

    @delsolsi213: Go

    Sorry, there are no up to date docs on the API. It's a feel around in the dark kind of situation right now. :\ EDIT: That was an exaggeration. All my source code is public on github.

    @mirolm: Go

    The plugin reads all data at startup. ;)

    I recently switched to MySQL storage and it works great. I was curious and looked into tables and noticed there are no primary keys. If plugin reads all data at server startup there will be no problem, but if tables get big and we select some rows adding indexes will be of great help.

    We can add primary key in 'griefprevention_playerdata' for 'name' column and 'griefprevention_claimdata' for 'id' column without worries.

    If a developer wanted to add support for grief prevention where can they find an api or how to do it? the developer of this plugin wants to add support to grief prevention.

    Update 13.9 is here!

    @maclarenss: Go

    Sure, go ahead and post a link. :)

    @BaxaLOL: Go

    You don't need to involve any permissions (ranks) for that - just have BuyCraft run the /acb <player> <block amount> command on package purchase.

  • Avatar of BaxaLOL BaxaLOL Jan 31, 2016 at 04:50 UTC - 0 likes

    Can anyone walk me through or point me in the right direction. Im trying to setup Ranks on my server where when purchased through BuyCraft, a certain amount of blocks are awarded as bonus blocks to that user upon completion of payment. I cannot find anywhere on how to set this up to award bonus blocks automatically via rank purchase through BuyCraft. Anyone know of a tutorial or something I can read from?

    @bigscary: Go

    I can give the file transfer via a link from sharing, or from your site the way you want?
