Grief Prevention

Grief Prevention

AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava, treetopping and more, so you don't have to undo any damage after the fact. 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 creativity.

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.

Project Status and Future

From BigScary: I've re-joined the project. Yes, I know many of you had a very bad experience with the beta builds, there were many bugs. We've rolled-back the buggy features which were added after I left the project, and then I added necessary anti-grief features for new game elements (leashes, hoppers, mounts). I've also added UUID support, and the current focus is improving performance - see below for how you can help!

Because all of the Bukkit staff have simultaneously quit the project, it's extremely unlikely that Bukkit will ever be updated to support Minecraft 1.8 or later servers. Also, there's a legal issue which resulted in all craftbukkit builds being removed from the internet in general. The law is slow, so that makes future bukkit versions even less likely.

Due to these circumstances, my current plan is to wait for a new mod platform to emerge (spongepowered.org is looking promising), then build a new grief prevention plugin for that new platform. Until then, Tux and I will perform the minimum maintenance needed for this project, which includes fixes for grief (including UUID support), bug report investigations, and bug fixes. Depending on how quickly the sponge platform gets ready to go, there may be time for me to slip in some minor tweaks here and there as well. There will be no major feature adds (like new config options or per world configs).

How to Upgrade to 8.0+ Builds

Starting with GriefPrevention 8.0.3, you can keep any claims and player data that was created by the broken "beta" builds. You just have to customize your config file again (a new config.yml will be generated in a folder named "GriefPreventionData").

Starting with GriefPrevention 8.1 which supports UUID (player name changes), GriefPrevention will do a one-time data update during boot. This can take a very long time - up to 1 second for each player who has ever played on your server. This is because GP has to contact Mojang via the interwebs to get the correct UUID for each player. At this time, it seems this process works well for offline mode and online mode servers, but there are mixed reviews for the hybrid "Bungee Cord" configuration (try it, but back-up first!). I'm not sure how GP can make it work for Bungee configs 100% correctly - if anyone has specific information on how solve this problem, please share it.

Please read! I need your input/help.

I'd like to redesign the bucket limiting option.

Players don't like that they can't dump water to water their farms in the early game, before they have a golden shovel to claim their farm separately from their house. Yes, they can work around this by farming on top of or under or in their house, but still they don't like it. When players don't like it, admins hear about it, and admins don't like that.

The reason for the current rule about not placing water outside of land claims is twofold. First, griefers can use buckets to make a REALLY big mess with only a few block changes (due to water spreading mechanics). Second, it's expensive for grief prevention to track the flow of fluids, which means server lag.

I would love to hear your ideas on other approaches to preventing griefers from griefing widely using buckets while still allowing players to build their ideal farms in early game.

    @ViperViolist: Go

    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.

    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.

    No?
