Grief Prevention

logo_big

AUTOMATICALLY PREVENTS ALL FORMS OF GRIEF, including build/break, theft, spam, fire, spawn camping, lava 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.

Please Vote for Grief Prevention

I've also posted Grief Prevention on the Spigot site, where plugins are ranked based on reviews. If you love GP, please take a couple of minutes to give GP your rating and leave a short review. Better rating and positive reviews will help server owners who look for plugins on the Spigot site make the safe choice (GP) instead of downloading something sketchy or incomplete. :) Thanks so much for all your support!

    @keytastic: Go

    I'm not saying it can't be done, just that I haven't bothered to code it. You can probably do it - one thing to watch out for is that there has to be a special file (I think _lastClaim or something like that) which has an integer in it which will be the next claim number (or maybe its the last claim number?). Try file mode on a test server to see an example.

    @MotheMan: Go

    So /ignoreclaims doesn't let you override? Sounds like an oops on my part. I'll get it fixed.

    @Kepler_: Go

    You don't want them crafting the required tool? Help me understand the motivation. Maybe we can come up with a good solution together.

  • Avatar of Kepler_ Kepler_ May 21, 2015 at 19:39 UTC - 0 likes

    Do you think it would be possible to add a feature to disable using gold shovels (or whatever the claim item is set to be), so players can't craft/use gold shovels normally, and can get them by typing a command?

    @bigscary

    You're a champion. Thanks for adding the pvp override. Slight problem with it is that when respecting claims i get the message that i'm in a pvp free zone, however when i do /ignoreclaims i get the message that the other player is in a pvp safe zone. Any idea why? do i need to add another permission node or change the config?

    Are you 100% positive there's no way to convert a database back to flat files? I'm tempted to do it by hand, if that will work. My host recently stopped being able to maintain a database connection to save its life. In fact, when I submitted a ticket they actually blamed your plugin >:( wth

    11.6.1 Updates

    • No claiming land during PvP combat.
    • Players offline for up to 90 days are now targetable with slash commands (was 30 days).
    • To get sign notifications in-game (in the chat), use griefprevention.eavesdropsigns, instead of just griefprevention.eavesdrop (which still works for whispers).
    • There's no more permission to automatically bypass pvp protections in land claims. Instead, use /ignoreclaims to toggle that bypass on and off.
    • Output from /claimslist and /trustlist is now customizable in messages.yml.
    • Stopped trying to auto-fill big holes in creative mode worlds. It was valuable when sea level is set correctly (see config file), but problematic when that setting is incorrect. I decided to make that trade-off.
    • Better logging for secondary storage (file system or database) problems.

    @Jikodis: Go

    See dutch's comment below. If that doesn't help, you can eliminate other plugins interfering as a possibility by temporarily disabling everything except grief prevention. If even that doesn't solve your problem, please share your config file's content, and explain exactly what you're seeing that you don't want (inside/outside claims? sea level or beneath sea level? tnt or creepers?).

    @TJW28: Go

    You mispelled it, and I forgot to add an alias for that common mispelling. I will add an alias. It's /separate.

    @Jikodis: Go

    The latest build is 421, try using the latest build.

    http://www.spigotmc.org/resources/griefprevention.1884/updates

    PLEASE be sure you're on a VERY recent 1.8.3 server version. Earlier versions of Spigot/CraftBukkit will not work with latest versions of GriefPrevention, due to breaking changes the Spigot team made somewhere along the way in 1.8.3 development. Symptoms of an outdated server build include errors logged during boot, explosions destroying blocks they shouldn't, and entities like item frames, animals, and armor stands not being protected.

    Loving the updates bigscary, though cant seem to get the new /seperate command to work, I have the Permission, griefprevention.separate, though just get unknown command in game.

  • Avatar of Jikodis Jikodis May 16, 2015 at 20:51 UTC - 0 likes

    I have the plugin installed and recently it seems to have stopped working. Specifically Creeper explosions and TNT do damage. I have explosions disabled in the area. The plugin still runs, but protection from explosions is not working.

    I am using Spigot 1.8.3 Build 373. My plugins are the following and are all up to date:

    • NoSwear
    • BattleArena
    • BattleTracker
    • ChestShop
    • GriefPrevention
    • Gringotts
    • Lockette
    • mcMMO
    • PermissionsEx
    • Spawner
    • Vault
    • WorldEdit

    11.6 Updates

    Added /ignore, so players can help themselves when there's no admin online to use /softmute and shut down a problematic chatter. Also helpful in reducing drama, which nobody likes. In addition to ignoring standard chat messages, an ignored player also can't use any whisper commands (see GP config file) targeting the player who's ignoring him.

    Added /separate, an administrative command which forces two players to ignore each other. They are not notified, and can't see the force-ignored player on their /ignorelist. When two players can't get along but you don't want to totally /softmute either of them, this is a good option. Required permission: griefprevention.separate

    @MotheMan: Go

    Maybe, let me check on that. I think it's a permission node you can take away.

    @Bobcat00: Go

    Great!

    @a1mbot: Go

    Sorry I don't think I will. I get why you want it, but it's a small payoff for a really big change (any change to the file format is a big deal). If those players are in your world\playerdata folders, then you should still see their names in-game rather than UUIDs. But I guess that's not the problem you're solving?

    @Kepler_: Go

    Sorry, it's too expensive (cpu cycles). :( Unless you have a somewhat severe problem that I haven't thought of as a result of liquids flowing out...?

    On nature regen, there's an option to toggle that for survival worlds but not for creative. The reason is this grief:

    1. Claim land.
    2. Make a HUGE mess with your unlimited blocks + flying.
    3. Abandon your claim.
    4. Repeat 1-3.

    Auto-restore makes this impossible. There's a warning message and a waiting period before anything gets regenerated, to give players a chance to re-claim the area if they want to keep their work.

    @GodsDead: Go

    Yeah, I know about that one. :\ It's a spigot bug - cancelling the teleport doesn't cancel the ender mite spawning. I logged the bug on hub.spigotmc.org. When it's fixed, a server update will fix this problem for you.

  • Avatar of GodsDead GodsDead May 15, 2015 at 23:10 UTC - 0 likes

    Small Bug, if you have enderpearls disabled in claims, which you should, people can just spam them since it gives the enderpearl back, there infinite, so they can just spam them until endermites spawn killing the person inside!
