Grief Prevention

Grief Prevention

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.

    @alyurbeis: Go

    That's a spigot/craftbukkit bug. You have to update your server to the latest (rerun buildtools.jar).

    @CrypticCabub: Go

    When other players who have that permission node log in,they will find that they also have the bonus blocks you assigned.

    @GodsDead: Go

    I thought you told me you didn't want them selling accrued blocks? Or did I misunderstand, and you meant that it's fine for players to sell them accrued blocks as long as they don't accrue them back?

    You cannot delete trust for a player that hasn't been on in a while, maybe to update their UUID from the conversion. This one I can't fix. The cost of looking through all players who've ever been on the server before is so high that it will crash some servers. :( I logged a bug against the spigot team for this when they first released 1.8, and they still haven't done anything about it.

    Sometimes Subclaims get deleted when the master claim is resized. I believe this is due to a fixed bug which caused SOME claims to get corrupted while it was still alive. The bug has been fixed, but the claims are not automatically repaired. If you delete and replace them (yes I know this is a pain in the ass), I expect they'll be permanently fixed.

    TNT is disabled everywhere, it does not do any damage in the wild, and if I turn on "BlockLandClaimExplosions" this makes them work again, but also destroys claims! We need an option to turn on TNT in the wild. I thought I thoroughly tested different combinations of the explosion settings, but I'll check again that this configuration works.

    A player can be sieged over and over again by different players, You mentioned a friend sieging them to add a cooldown; at least make it togglable, so we can deal with troublesome players, this would only be a select few. In what way do you want it toggleable? Do you mean a config option, or a per-player permission? Please go into a little more detail here so that I don't code up something and find out I misunderstood the ask.

    EDIT: If a player doesn't want to be besieged, why is he even playing on a server with siege mode enabled? He should be excited for the opportunity - there are so many ways to win even against overwhelming odds, because he has the home advantage. Hidden pitfalls and lava dispensers to kill his enemies. Build an escape tunnel to sneak out. Throw an ender pearl over their heads to get a head start so they can't catch you. Go out and fight them. Add arrow slits so you can shoot at them from relative safety. It's a solvable problem that the player should be working on, not you - don't you think?

    Random players have their claim blocks vanish without claiming or doing anything to change their claim blocks, One of my staff members claim blocks has gone from 6000 to 250 from last night to today. I have zero idea what could be causing this, or where to start looking. Adding to the puzzle, no one else has complained (noticed?). I will keep thinking about this and try to come up with something. In the meantime, I'm already working on more detailed logging that may provide some hints.

    @bigscary: Go

    Yes im in Database mode, I figured out the /sellclaim issue, Its actually something ive already covered a few times, so I feel a little rude repeating (sorry).

    • Sellclaims work as intended, removing from the bonusblocks column, this issue is when this hits 0 you cant sell any more blocks even if you have spare blocks to sell, what needs to happen is a check to see if you have excess claim blocks, if so then that bonusblocks will go into minus instead of stopping at 0, this way you can remove these from the overall available claim blocks so they the are indeed deducted.

    We have also found some more bugs to add on top of the ones I already reported, so Ill update the list here:

    • You cannot delete trust for a player that hasn't been on in a while, maybe to update their UUID from the conversion.
    • Sometimes Subclaims get deleted when the master claim is resized
    • TNT is disabled everywhere, it does not do any damage in the wild, and if I turn on "BlockLandClaimExplosions" this makes them work again, but also destroys claims! We need an option to turn on TNT in the wild.
    • A player can be sieged over and over again by different players, You mentioned a friend sieging them to add a cooldown; at least make it togglable, so we can deal with troublesome players, this would only be a select few.
    • Sellclaimblocks is re-reported with a fix above.

    <<reply 2539057>>

    If you are in linux you could change the appropriate line in each GP player file via batch script, like:

    for all files in GriefpreventionData/PlayerData do

    // get the 2nd line (bonus claim blocks)
    bonusblocks=`head -2 <file> | tail -1`

    // add x to it (the number you want to give each player...here e.g. 10)
    bonusblocks=$(($bonusblocks + 10))

    // replace the old bonus claim line (line 2) with the new one
    sed '2 c\ > $bonusblocks' <filename>

    Needs a bit trial&error to get this running as it should I guess as I am always not sure about the correct syntax. But should be the easiest to do something like this when server is down (e.g. in a restart).

    Hey, it's me again :)

    Turns out /acb [permissions.everybody.has] {amount} is only assigning claim blocks to people who are currently online. Is there any way I can assign claimblocks to everybody (online and off) at a set time without having to maintain a list of all students on our servers? Hoping to be able to schedule the command to assign claimblocks every weekend.

    Great plugin, thanks for all the hard work. God bless, CrypticCabub (VicePrincipal_Cryptic, MinecraftHomeschool)

    11.3.2 Updates

    • Added support for RoyalCommands plugin.
    • Fixed /restorenature bugs associated with setting the sea level very low.

    @Shayd713: Go@OddWhirled: Go

    I tried very hard to reproduce these issues with latest 1.8.3 spigot and latest GP, and couldn't. I suspect your 1.8.3 version is an old 1.8.3 version - try updating by re-running buildtools.jar. If that doesn't help, then please share with me the following:

    • Output from /version
    • Output from /version griefprevention
    • Any errors in your logs from around the time you had the problem (use pastebin.com).
    • Your complete config file (use pastebin for this too).
    • Detailed steps for reproducing the problem (make sure you can personally make it happen on your server first, then tell me what you did to make it happen).

    @OddWhirled: Go

    I wish I could tell people exactly what build they need, but the builds aren't numbered. They just all have some crazy GUID, so it's unclear which builds are newer versus older (boo Spigot team!).

    I do know about the fall damage thing. Cancelling the "player changed a block by stepping on it" event also cancels the damage. I logged a spigot bug but they haven't fixed it.

    @Duffa13: Go

    Yep it's now griefprevention.claimslistother, I think. Check the docs.

    Thx OddWhirled it did solve my problems by changing gamemode :) Been trying to figure out for a week now what has been wrong or how to give permissions to this...

  • Avatar of Duffa13 Duffa13 Apr 15, 2015 at 12:38 UTC - 0 likes

    Has the permission node for /claimslist <others> changed since version 7.7? I have given both GriefPrevention.Commands.claimslist & griefprevention.claimslistother and I am getting "You don't have permission to get information about another players land claims" Thanks!

  • Avatar of OddWhirled OddWhirled Apr 15, 2015 at 09:30 UTC - 0 likes

    @Shayd713: Go

    Make sure to run BuildTools #35 to get the VERY latest version of Spigot 1.8.3. If you type /version in the game and it does not say "You are running the latest version" then it may not work.
