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 continued the project from there as if I hadn't left in the first place. So far, I've added UUID support, greatly improved performance during play time and boot time, blocked new grief strategies made possible by changes to the game since I last worked on the project, cleaned up the config files, and tweaked several features for much improved player and administrator experiences.

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, I will continue working on this project as I always have. No other project I've ever worked on in my career as a software engineer compares to GriefPrevention's mix of fun, challenge, and importance to the community.

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!). In any case, please back up before you take on this major update. If you have any problems, restore your data from backup, use the older version of GP which was working for you for now, and get your logs to me so I can investigate. :)

    @dhannyjsb: Go

    Couple of very serious bugs. If you're running it, check your logs.

    @switorik: Go

    Yep. On the todo list.

    @mcly: Go

    You need to figure out the correct yaml syntax. Usually colons are problematic. As for nether portals, that's a won't fix for now - take the portal down and put up another outside the land claim - I think that will reconnect the nether portal to the new overworld portal. The problem is that it's impossible to know who's making a nether portal - so it's either never allow them to pop up in claims, or always. I choose always because it's so rare to get a new nether portal in general, unless you're running some plugin that changes how they're placed and linked. I'm interested in solving this problem, just haven't come up with a good solution.

    Hi, just some bugs:

    1. I still can't change the short links in language file 2. Nether portals are randomly appearing at spawn, inside administrative claims.

    Thanks.

    Can you add the ability to see all claims around you when you shift click the ground?

    @bigscary: Go

    why ?

  • Avatar of bigscary bigscary Oct 31, 2014 at 04:19 UTC - 0 likes

    Looks like 10 of you got 8.6.3 - it's broken, sorry. :( Please go back to 8.6.2.

    @Bobcat00: Go

    I should update the docs - now only building extends your claim downward, not breaking (performance boost).

    @LordDWT: Go

    As a player digs or builds underneath his claim, his claim automatically sinks lower with him. So all he has to do is break or place a block further down within the x and z limits of his claim, and his claim will extend deeper automatically. (In the other direction, I think all claims automatically extend to the sky.)

    You can't have multiple claims stacked vertically.

  • Avatar of LordDWT LordDWT Oct 31, 2014 at 00:23 UTC - 0 likes

    So if one makes a claim and it extends in the ground say 10 blocks and you wanted to claim more area underneath your claim or someone else for that matter how would you do that? It always says overlapping claim. If you abandonclaim and then reclaim further down that it a major chore for large claims and still no one can claim anywhere underneath your claim.

    @bigscary: Go

    I think sk89q has actually made a system in 1.7.10 to use game registries from a plugin. I'm not positive on that, though, but I know he frequents his IRC channel at http:skq.me/irc/irc.esper.net/sk89q/ if you want to ask. I could actually ask for you, if you're pressed for time. Just let me know if you want me to!

    Edit: Actually, I know Essentials works with game registry string-ids since I remember typing in the strings to give items.

    8.6.2 Updates

    • Dying and shearing sheep in a land claim now requires /containerTrust or higher permission.
    • Improved underwater claim management. I'll bet you didn't realize this was a thing, did you? ;)
    • Stick and shovel tools now reach through water with right click.
    • When the player is underwater, visualizations will "stick" to the ground or structures under the water rather than to the water's surface.
