Anti X-Ray
PREVENTS cheaters from taking all the good stuff for themselves, without the tremendous overhead of Orebfuscator.
How does it work?
Basically, players are limited in the amount of valuable ores they can mine, based on their play time on the server. Legitimate, non-cheating players probably won't notice because the default limits are generous, but xrayers will be blocked from mining ore too quickly. So cheaters can still cheat, but they can't take more than a non-cheating player's reasonable share of ore. So their only gain is avoiding monsters while digging. They can't mine their first diamonds/"other good stuff" sooner than non-cheating players, and they can't take more total than they could if they weren't cheating.
How does this compare to Spigot AntiXRay and Orebfuscator?
The trouble with these and similar plugins is that while they're incredibly effective, they're very, very expensive to run. They consume a lot of CPU cycles doing deep packet inspection and manipulation, and they consume a lot of RAM trying to cache the results in memory. Small servers simply can't afford it, and larger servers have to cut back on their max players or other plugins. Any server which doesn't have enough CPU or memory may suffer heavy lag and crashes, other servers are simply spending too many cycles to stop a few cheaters - it's not a good trade-off.
In contrast, Anti-XRay is extremely cheap. It doesn't do any heavy processing, and consumes very little memory. It's true that technically cheaters can still use xray to find ores and dungeon chests (Mojang hasn't really made those worth hiding), but they're limited in how much advantage they get out of it. Basically, you're allowing players to cheat (but only very little!) to save immensely on CPU cycles and RAM.
How does this compare to ore loggers and ratio reporters?
Those simply don't work. Viewing a report to determine who has been x-raying only helps you catch players AFTER they've done permanent damage, removing massive amounts of diamonds so that non-cheating players can't find any. Banning the cheaters doesn't actually solve the problem, because it doesn't put the diamonds back in the ground AND more cheaters will soon replace those guys, so the problem continues. Also, this approach requires administrators to actively work to catch cheaters. An automatic approach like that provided by this plugin makes more sense.
Anti X-Ray keeps ores in the ground so that non-cheating players can find them. By placing limits on the amount of valuable resources a player can mine based on his play time on the server, Anti X-Ray guarantees that cheaters don't get greedy. They can still cheat a little, but not to the extreme of ruining the fun of other players. In fact, most new-to-server cheaters just leave the server to find another server where they can cheat without limits, solving your cheating problem very well.
Versus ore loggers, you're actually SOLVING the problem, and doing it in a fully automated fashion. Versus ore obfuscation solutions, you're saving RAM and CPU.
The Details
Players have an invisible currency which grows while they play (up to a maximum amount). Players who aren't actively playing (idling) don't gain any. When players break a valuable block, their total is reduced. If they don't have enough to break the block, they get a message explaining that they've reached their limit, and will have to wait X minutes before they can break that block.
Players who have been playing on your server since before you installed this plugin will start maxed-out to make the transition go smoothly.
Players who are NEW to your server after you install this plugin will start with a negative amount. This will prevent players from logging in and immediately x-raying to get valuables like diamond, because they won't have played enough yet to reasonably mine diamonds without cheating.
Yes, it's possible that some players who aren't cheating will run into the limits. It's my goal to adjust the default limits to minimize the chance of impacting legitimate players, while at the same time stopping xrayers from going crazy and taking all the valuable ore for themselves. If a player complains, these are the common scenarios:
- That player is a cheater, and is trying to convince you to disable the plugin or give him permission to bypass it so that he can cheat more.
- That player has "raided" someone else's existing mine instead of exploring on his own, allowing him to find diamond within the first hour of joining the server for the first time. Tell him to stop being lazy and earn his own diamonds.
- The player is EXTREMELY lucky, and managed to survive a reckless cave diving expedition without bothering to grow food or make armor and weapons. This is extremely unlikely - the player is probably cheating.
- That player is "branch mining", which involves tediously mining in long, straight, parallel tunnels near bedrock to collect lots of diamond. Chances are that player has an unhealthy obsession with diamonds, and already has a million more diamonds than he can possibly use. For this case, I recommend advising the player to take a break from mining when he hits the limit. If you give a player like this the bypass permission, he will grab most of the diamond in the area, robbing other players of the opportunity (even though he's not cheating, he's potentially causing a problem).
Catching Cheaters
This plugin will do a good job of preventing cheaters from benefiting from xray. However if you'd also like to actually catch and ban them, there's a configuration option to make a log entry and notify moderators (permission: antixray.monitorxrayers or op) when a player reaches the mining speed limit. This does NOT necessarily mean the player is cheating (read below!), but teleporting to the reported location will often be enough to determine whether the player was cheating or not. Since the 1.3 update, the Vanilla /tp command will accept coordinates, making these investigations very easy even when the player is offline.
What are the indications of a cheater?
It's impossible to know absolutely for certain whether a player is cheating or not unless you're looking over his shoulder while he plays. However all of these are indicators of likely cheating.
- Mines straight down. Xrayers don't fear lava because they can see through the ground.
- Mines in the dark. Xrayers don't need light - most of their blocks are transparent anyway.
- Mines in very long, single-block-wide tunnels (possibly winding), with very few, very short branches. You may notice a distinct lack of any pattern - unlike a "strip miner" who digs straight, parallel tunnels very close together, an xrayer's tunnels "wander". Xrayers don't need a pattern to be efficient, because they can see exactly where all the ore is, and so they can always take the shortest path to the next node.
- Starts mining before he even builds a rudimentary shelter, and without bothering to start even a small farm. Xrayers can see through most blocks, so they see caverns and monsters, and dig around them instead of fightning them.
- Carries very few supplies with him and doesn't wear armor while mining. May not even have a sword. Xrayers can see through most blocks, so they see caverns and monsters, and dig around them instead of fightning them.
- Finds diamonds VERY early after joining the server. Xrayers don't have to look for diamonds. They know exactly where they are and can see the shortest path immediately after logging in.
- Complains frequently, "Why do I have to wait to mine diamonds?!", while other players don't seem to notice the "problem".
- A VERY high ore-to-stone ratio. This plugin doesn't measure that, but you could supplement this with an ore logging plugin if you really want to catch and ban cheaters (this plugin will limit their cheating so that they don't mine more valuables than non-cheating players). Because xrayers can see the shortest path to any ore node, they minimize the number of stone blocks broken as they mine.
Setup and Configuration
Beyond just putting the .jar file in your plugins folder, all of these steps are optional. There is no database required - that is also optional.
Tweaking the Ore-per-Hour Ratio
Please do not adjust the diamond mining rate, starting values, etc, until you have actually tried the defaults for a day or so. Over-thinking them will likely lead to you choosing bad values which either prevent non cheaters from mining, or allow cheaters to cheat too much.
In the config file, you'll find something like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
AntiXRay: EnableMetricsTracking: true NewPlayerStartingPoints: -400 PointsEarnedPerHourPlayed: 800 MaximumPoints: 1600 IgnoreMaxPointsForBlockRatio: true ExemptCreativeModePlayers: true NotifyOnMiningLimitReached: false DefaultMaxHeight: 63 ProtectedBlockValues: EMERALD_ORE: Value: 50 MaxHeight: 35 DIAMOND_ORE: Value: 100 MaxHeight: 20 Worlds: world: '' world_nether: DefaultMaxHeight: 256 world_the_end: DefaultMaxHeight: 256 |
EnableMetricsTracking let's you disable metrics tracking. More about this at the bottom of this page.
New player starting points are how many points an entirely new player to your server (meaning he's NEVER been on your server before) will start with. The points are used to break blocks, like DIAMOND_ORE, which by default costs 100 points.
Points earned per hour played is the speed at which players get points. In this example, players get 800 points per hour, so on average, they can mine 8 diamonds per hour indefinitely without ever being temporarily blocked from mining.
Maximum points is the "buffer" players build up. Players don't spend ALL their time mining for diamonds, so this buffer gradually fills up with points. This means players who take breaks from mining will be less likely to encounter the mining speed limit.
In this example, because the starting points setting is much less than the cost of mining a diamond, this means that an entirely new player who has just joined the server can't mine ANY diamonds right away. This helps stop xrayers, who often start xraying right away, and will likely encounter the limit and either quit or complain (the latter helps you catch them).
You can add other ores as well, but generally xrayers don't bother to gobble up non-diamond ores, so those other ores probably aren't worth spending CPU cycles on tracking.
Cutom block definitions allow you to define new ore names by id and sub id (sometimes also called data). Read more about this below in the tekkit related section.
Protected block values is the place where you write down the default values for the ores you want to be protected by default in all worlds for which the plugin is enabled for. Additionally you can provide an ore-specific default maxHeight value for each of those. Read about maxHeight values below.
Default max height determines the default max height for all ores which don't have a specific maxHeight value set. Players are free to mine (break) as much ores they want above this height. This is useful for example to block players from mining to many diamond ore (which, in a default minecraft world, is only located below height 16), but at the same time allow them to place and break it again in their houses above that height with their fortune pickaxes if they like too, without having to reduce their point stock for that.
Now, there is the "Worlds" section:
This section determines the worlds in which AntiXRay shall be enabled and at the same time allows you to overwrite some of the default values specific for each world:
DefaultMaxHeight will overwrite the default max height from above, but only for this world.
ProtectedBlocks lets you add or overwrite ore values and ore specific max heights for this world.
In the example snippet below you can see how to use that: the example sets the value of diamond ore to 75 and it's height limit to 63 in world 'world' (maybe this world uses some custom world generator which generates slightly more diamond ore, up to height 63..).
Also you can see that the default max heights were increased to 256 in the nether and end worlds. By default players wouldn't be able to, for example, break diamond ore there (after placing it there of course) below height 20, because the section of default protected blocks from above restricts diamond ore by default in all enabled worlds if it is mined below height 20.
The world specific default max height value however overwrites all previously default max height values. So players can freely place and mine diamond ore again in the nether and the end.
In general heights get overwritten in this hierarchy:
default max height < default protected ore max height
< world specific default max height < world specific ore max height
More information on minecrafts default ore heights can be found in the minecraft wiki: http:www.minecraftwiki.net/wiki/Ore
If you want to add a world but not want to overwrite any default values or heights do as follows:
Let's say the world you want to add in order to enable AntiXRay in it is called "mining_world". Then create an (empty) section with the worlds name by putting 2 quotation marks behind the colon without anything between these, like so:
1 2 3 4 5 6 7 8 9 10 11 |
Worlds: mining_world: "" world: ProtectedBlocks: DIAMOND_ORE: Value: 75 MaxHeight: 63 world_nether: DefaultMaxHeight: 256 world_the_end: DefaultMaxHeight: 256 |
Without the colon or the empty quotation marks the plugin wouldn't be able to read the world name and it would get removed after the next reload.
More detailed block type specifications and Mods
You can also specify block types by id instead of name. This might be useful if you want to protect some custom blocks which got added by some mod.
Note however that there are mods this plugin doesn't quite work well for because they introduce new methods of mining which completely bypass plugins.
Also note that AntiXRay will automatically replace the block ids in the config with the material name, if it finds a matching one.
Also you can specify the data value (subid) for protected blocks by adding the data value to the block name/id separated by a tilde (~). Data values for blocks are usually used to differ between different states of the block (ex. the rotation of log or stairs, whether or not redstone ore is glowing, the color of wool, the growing state of plants, etc.). If you don't specify a data value it will default to -1, which is used to specify that the data value shall be ignored. This could look like this:
1 2 3 4 5 6 |
ProtectedBlockValues: 999~12: # maybe some custom modded block Value: 50 MaxHeight: 35 WOOL~14: # red wool, for example purposes Value: 100 |
Where's the Database Option?
By design, there is no database option. This is one of a few cases where using a database is definitely more trouble than it's worth, and possibly detrimental to performance. There are only TWO integer values stored per player. That integers are read from file only once per login, and written to file once per logout (or when you shut down the server). There's no need for a database, and besides that, it will slow your boot trying to establish the initial connection.
I used to have database support, and one of the problems was that the database was used so infrequently that the connection would fall asleep. I will not add the database option back in unless in the future, something about the above changes so that there's either a LOT more data, or very frequent changes to data.
Using a Block Ratio Instead
If you'd rather require players to mine more coal or break more stone to earn more valuable ores instead of making them wait an amount of time, you need to do three things. First, set the points per hour to zero. Second, set the "cost" of the other blocks you want players to break to a negative amount. Then when the player breaks those blocks, he will GAIN points, taking him closer to mining. Finally, update your messages.yml to explain that the player must break more stone or other ores (depending on your configuration), instead of telling him he will get more points by waiting. For example, if you wanted to allow players to mine one diamond per 100 stone broken, you'd do this:
- points per hour: 0
- starting points: 0
- DIAMOND_ORE: 100
- STONE: -1
- In messages.yml: "You're finding a lot of diamond! You have to break more stone before you can collect this ore."
Commands
/antixray help -> Overview over the possible commands.
/antixray reload -> Reloads the configuration and message files.
/antixray check [player] -> Shows you your or another players current points. I do NOT recommend you to give your players the ability to check their current points as they can use this information to avoid reaching their limit in order to avoid that you get a notification about them!
/antixray set <points|counter> -> Sets the players points or counter value. I do NOT recommend you to use this to reset your players points whenever they reach their limit (by doing so, you are wasting effort and you will make the limit useless)! This command is mainly meant for debugging purposes and trying out different mining limit settings.
Permission nodes
antixray.monitorxrayers (default: op) -> The player will get notified when a player has reached his mining limits and notifications are enabled.
antixray.bypass (default: false) -> Allows the player to freely mine any block without being checked by Anti X-Ray. Usage on own risk..
antixray.help (default: false) -> Allows a player to view the help page which contains information about the commands. Default: op
antixray.reload (default: op) -> Allows a player to reload the antixray configuration and message file.
antixray.check.self (default: op) -> Allows a player to view his amount of remaining mining points.
antixray.check.others (default: op) -> Allows a player to view an other players amount of remaining mining points.
antixray.set (default: op) -> Allows the setting of a players stored values, like the amount of remaining mining points.
Notice
This plugin uses Hidendra's Metrics class to report usage stats to mcstats.org. This is giving me (and you) an idea of how many servers are actually using this plugin. You can disable this by setting "AntiXRay.EnableMetricsTracking" to 'false' in the config.

@bigscary
Oh oh, I understand, so for each diamond it TAKES currency! Sorry I've been super tired when i get around to editing this plugin...Don't know how that keeps happening...
@bigscary
Thanks, makes sense.
@krone6
Oh, I think I understand your confusion. You have it in reverse - players gain points for playing on the server, and lose points when they mine a diamond (or other valuable ores you have added in your config). If they don't have the # of points needed to mind a particular block, they will not be allowed to mine it.
I will clarify the configuration above. :)
@MCFKilty
It means you can't mine any diamonds for the first half hour. Since players start at -400 and gain 800 blocks for a full hour, it would be a little over half an hour before they'd have enough to mine a diamond (which requires 100 points).
I'm also confused on this. What is this saying?
As a suggestion change the config file to have these options: (Note, it's just a suggestion, up to you to take these into consideration)
1: Points players enter with 2: Maximum points per hour 3: Points per ore block (with listed blocks each ore gives)
This is similar to loyalty points. A person coming in with 0 points will gain 1 point per diamond ore. He can not have no more than 15 for example. If I want to include gold ore then both ores will count towards 15 points. If i really want to stop diamond ore griefing I can make each diamond block give 5 points and gold give 1.
That system in my opinion will make this plugin even better, though it's already a great addition alongside orebfuscator.
Another amazing plugin... Thanks bigscary!
Love the idea! This plugin works wonderfully, keep up the good work! I wish I could stop there but I'm a tad bit confused not he config?
Does this mean that if you play for two hours you can't mine anything? Should there be a ' - ' in front of the 800?
1.2 Updates!
MySQL is now supported. If you prefer, you can use a database instead of the file system to store your data by specifying some database information in the config file. For very large servers (lots of players online at once), this may improve performance by eliminating direct file access. Please don't use it unless you're having a performance problem OR you or someone on your administrative team is familiar with common database operations, otherwise you will just be making your life more difficult unnecessarily. :)
I will update the documentation later. For now, this may help. A database URL looks like this:
jdbc:mysql://localhost:3306/myDatabaseName
The last bit is the database name. You have to be sure the database is created before switching AntiXRay to database mode. It will do the rest (like creating the necessary tables). At the mySQL command prompt, you'd create a database with something like "create database databasename".
Please, if you have a problem with your database itself, do not come to me for help. I won't teach anyone how to install mySQL, install the JDBC driver, or learn the SQL commands for viewing/editing data, backing up data, or migrating data to another server. You can find all this information elsewhere on the internet. :) I may provide some relevant links in the documentation later.
Hey all, since the last update of the defaults, I haven't had any complaints except for from obvious xrayers. I hope this is the same for you. :) Please feel free to comment, so I can confirm. Thanks!
@khanjal
I'm very glad you like it. My next goal is to add an option to use a database.
Love your work! Keep it up!
1.1 Updates!
@bigscary
Thanks! Many plugins don't deal with /reload too well so I never use it since I have a lot of plugins. I have used it before and it blew things up so I denied permission to it completely.
@ryvix
You can use /reload. It sounds like you're trying to find a good balance. Let me deal with that headache directly, instead of adding a lot of diagnostic stuff for everyone. I'll tweak the default settings some more. One diamond per 5 minutes might be okay.. that's 12 per hour, so a medium sized vein every 15 minutes. I'll try something alittle lower first, coupled with a shorter time to the first diamond.
@kahlilnc
I'm very glad you like it! If you notice players are complaining and you're sure they're not cheating (teleport to them and look at their mining area), let me know. I'm still tweaking defaults to avoid bothering legit players.
@np98765
Yep, you can use them both together. Mine will keep them from xraying too much, and yours would help you identify them for banning if they show patience (they usually don't).
Hi there,
I'm currently using orebfuscator. It's great, but I can feel that it's using a ton of resources. I also have the plugin OreRatio, that tells me how much a player has mined.
If I used OreRatio in conjunction with this plugin, would I be able to catch the X-rayers? I can some people being persistent enough to Xray as much as they can, and maxing out on their limits.
So, would I still be able to see that they were Xraying with OreRatio (using the default settings)?
Thanks!
Very interesting got tired of the other anti xrays, loggers are not efficient enough and the one that modify the ores them self are just to laggy. :D I tested this today and it works fine with otherdrops thank you very much!
I had a new player cave explorer today who maxed out right away. I followed them around and they weren't xraying. But other people are hitting the limit a lot as well who weren't new players to begin with so I raised the amount they gain per hour. Now they get enough to mine another in 5 minutes, I don't know if thats really all that good or not but I suppose it slows them down. Maybe I will raise the max instead.
It would be awesome if I could:
@Nickshelton80
Yeah, use the config file. Set the points per hour higher or lower.
So is there no-way to configurate the max diamonds per hour? Or am i just missing something? ^_^
