LRR Minecraft Server

[SilPho]

Cool. Thanks Hosk. Shame to hear about Templemir, though I never realised it was underwater, that's awesome!

[Dutch guy]

I just came home from vacation. Lets say I'm very disappointed that someone would be an {redacted expletive} and flood Templemir. I had expected better from people.

[AdmiralMemo]

How non-trivial would it be to just disable TNT (and TNT Minecarts)?

I have no idea. I don't even know if it can be done in vanilla.

I didn't see what happened to Templemir, but... a giant glass dome needs not TNT to be griefed.

From the pattern of damage, I don't believe TNT was needed. From the pattern of damage, it looks like someone broke the glass from the outside in various places, and then, after the flood, floated in and damaged more stuff.

The LRRCraft.com site says I need to ask a mod for permission to build. Does that mean the server is in a kind of spectator mode until permission is granted?

If so, can I request permission for 'SilPho' now or do I have to sign in first?

Yes, but the server is only set to Mods currently, due to researching the griefing (and me going to a convention and Osprey hasn't gotten back to me yet). When you sign in, you'll be stuck in Adventure Mode with Mining Fatigue on. To get that turned off, there's a two-switch auth plate. Also, for build permissions, it's mainly a formality. If you're building in an area that doesn't have underground concerns and you won't be bumping into other players' builds, you're typically fine.

Im pretty sure that the server is in safe mode right now while AdmiralMemo finishes fixing Templemir which is the underwater base you can sorta see on the map from 0 to -150X and 0 to 180 Y between the inverted pyramid and the lighthouse.

Apparently someone broke some of the roof bricks which flooded it and washed away a bunch of work.

After that situation gets resolved you can log in at any time when there is a Mod on and they will give you a quick tour of spawn, authorize you to break bricks help you get to a starting location.

I believe it's fixed, but still waiting on Osprey for final confirmation, and also going to get searching on the logs to find out who did it.

This is the stuff that makes me hate people with a passion.

Looked into it a bit myself, apparently it would indeed require a server mod, but it looks like a lot of mod packs offer this function. Dunno what we've already got on the server, though.

And even if this run of griefing wasn't done with TNT, it just seems the kind of block that does more harm than good, ya know?

[AdmiralMemo]

This is true. What we have on the server is pretty much nothing.

[King Kool]

I do have a large supply of gunpowder, but that's for splash potions.

[Volafortis]

Honestly, I think just keeping gunpowder and TNT away from spawn would have about the same effect as outright disabling it.

[SilPho]

I know it's possible to build a clock hooked up to some command blocks that scan certain areas for primed TNT entities and remove or replace them.

But I have no idea how much server load that would cause.

[AdmiralMemo]

I know it's possible to build a clock hooked up to some command blocks that scan certain areas for primed TNT entities and remove or replace them.

But I have no idea how much server load that would cause.

In 1.7? I'd have to test each block individually, which would be a nightmare. In 1.8? I could test a whole area at once, which would be easy.

So... Another reason for 1.8 to come quickly?

[SilPho]

I looked it up, turns out it is a feature in 1.8 after all.

I got the idea from one of Sethbling's videos (Link), which I guess was using a snapshot since the @e selector doesn't work in 1.7.X. Essentially it's a clock that replaces primed TNT with creepers that instantly explode, but it could just kill the TNT instead, which would effectively disable TNT.

So I guess it's possible in 1.8, but since I'm not very experienced with command blocks or running a server I don't know if it's a good idea.

[AdmiralMemo]

Well, if it's possible, instead of creepers, I'd just replace them with air blocks. (Or maybe some other signature block like obsidian or something if air won't work.)

[Lord Hosk]

I thought you said it wasnt dynamite anyways but instead someone breaking blocks.

Was there a second act of dynamite vandalism that I missed?

[SilPho]

We're only speculating about future prevention measures, TNT was apparently not responsible for this attack.

Actually, come to think of it, just clearing every player's inventory of TNT every 5 seconds or so is probably just as effective and much less server intensive than constantly checking for the primed stuff.

[AdmiralMemo]

Also, I decided a couple of days ago that I'm opening up the server as soon as I get a chance to check the logs and find the culprit, with or without Osprey. This has gone on long enough.

[SAJewers]

There are legit uses for TNT though. It's not just for greifing.

I think a better option would be to have a scoreboard objective on the side that lists all players with TNT and how much they have in their inventory. That way, people can still use TNT for legit purposes, while telling mods who has TNT on them.

[AdmiralMemo]

1. Sounds interesting, but how would that be set up? Do you know how to technically achieve that?
2. If you EVER have TNT on you, your score will stay up there, even if it goes back to zero. I've found the right-side score display just disappears if there are too many people with a score. So, slowly, people who have ever had TNT will build up and eventually, the score display will be useless because it doesn't display. But, would it be long enough that it'll take a while before that happens? And if so, by then, would we have a better solution?

[SAJewers]

I'm a total noob with command blocks (I haven't really used them at all), but the wiki does say there's a "scoreboard players reset command" which can clear the scoreboard.

After some searching, you should be able create a scoreboard object "TNT" that increments everytime someone places TNT, then periodically use "scoreboard players reset @a TNT" to reset that scoreboard for all players. Seemed to work in a Singleplayer creative, no idea if it will work on a multiplayer survival.

[Volafortis]

If you can test for any player placing TNT, I'd just have a command block display a message like "<name> is using TNT! Stand clear!" whenever a player places a TNT block (with a 30 second or so interval between messages so it doesn't spam the logs.)

Easy way to produce a list of culprits, and far less bookkeeping.

And again, this doesn't really solve the non-TNT grief, although I agree it'd be nice to have a system ready before it's needed.

[AdmiralMemo]

I don't currently know how to detect the placement of blocks, other than testing each block in the world with "Is this TNT?" and that would be ridiculous.

[SAJewers]

/scoreboard objectives add TNT stat.useItem.minecraft.tnt will create a scoreboard objective that increments a players "TNT" score by 1 everytime they place TNT. If possible, you could have it check that scoreboard, then list in chat all players with a score greater than 0, then clear it with /scoreboard players reset @a TNT

[AdmiralMemo]

OK. That actually works. Might implement that.

[Dutch guy]

thats pretty clever.

[AdmiralMemo]

OK, working on my investigation, Weeden_Project was the last to use the Templemir rails, on July 23, 2014 at 22:03:44 server time. I first found the damage on July 27, 2014 at 00:20:38 server time. Investigation still proceeding.

axelpheonix mentioned something about dynamite... Worrying...

Current suspect is Psychogeist, who went for a VERY long time and never got authorized, but even mining fatigue and adventure mode wouldn't stop glass and stone breaking with a pickaxe.

Oooh... Maybe a new suspect... DanielBeas0829 kept getting kicked for flying. Maybe hacked client? And the coordinates as he continued to log in... Look about right...

OK, so with no current other prospects, I'm thinking DanielBeas0829 did it. That's worrisome because I personally authorized him and went looking for land with him. He seemed like a good guy. My only hope is that his account was hacked and he personally isn't at fault.

Anyway, the server's back on.

[Sky_rider19]

I'm assuming the dynamite I was referring too is when I was clearing out some of the hills around my area to make it easier for horses to come through. Apart from that I haven't used TNT at all

[AdmiralMemo]

Yeah, the coordinates weren't right for that anyway. It was just a stream-of-consciousness post.
