Config

The config is divided in multiple sections (general, advanced, cache, obfuscation, proximity). We will explain each of them in detail in the following. The current version of the config is 3 and should not be edited unless you have good reason to do so.

general

name	description	default value
checkForUpdates	Enables checking for updates on server startup and whenever a player with the orebfuscator.admin permission joins	true
updateOnBlockDamage	Whether block damage (when a player is in the process of digging/breaking a block) should count as block update	true
bypassNotification	Notify a player that he is bypassing obfuscation	true
ignoreSpectator	When enabled stops spectators from revealing proximity obfuscated blocks if they get to close, useful for servers where every player has access to spectator mode	false
updateRadius	Radius of neighboring blocks to deobfuscate once a block gets updated (break, explode, burn, etc.)	2

advanced

❗ Since version 5.2.2 Primarily contains more advanced settings for tuning performance and how system resources are used. Proceed with caution!

name	description	default value
verbose	Enables more verbose logging. Mostly useful as an extra diagnostic step.	false
maxMillisecondPerTick	Maximum millisecond per tick used by the obfuscation dispatcher (for further information click here)	10
obfuscationWorkerThreads	Number of threads used for obfuscation	-1 (-1 uses {processor count})
obfuscationTimeout	Chunk obfuscation timeout in milliseconds, if reached obfuscation for chunk will get cancelled	10000
proximityHiderThreads	Number of threads used for proximity deobfuscation	-1 (-1 uses {processor count} / 2)
proximityDefaultBucketSize	How many players one proximity thread should handle	50
proximityThreadCheckInterval	How often a proximity thread should check if a player needs updates (player position/rotation changed)	50
proximityPlayerCheckInterval	How often a player should get proximity updates regardless of position and rotation changes in milliseconds	5000

cache

The cache is used to cache already obfuscated chunks and has two levels. Level one is a memory cache which has a max size and an expiration time. Level two is a disk cache which stores chunks that got evicted from the level one cache. Chunks get evicted when they exceed the expiration time or the cache reached its max size and the chunk is the oldest in terms of last access. When a chunk is requested from cache the cache system will first check level one then level two and if both don't contain the chunk it gets obfuscated and put in level one cache. Since version 5.1.0 the whole cache system is asynchronous and doesn't use the main thread anymore.

name	description	default value
enabled	Whether the cache should be used or not	true
baseDirectory	Directory which the cache should be saved to once flushed from memory. This path is relative to the directory your worlds are in	'orebfuscator_cache/'
maximumOpenRegionFiles	Maximum number of concurrently open region files (file descriptors)	256
deleteRegionFilesAfterAccess	Minimum amount of time between the last access of region file and its deletion	172800000‬ (2d in ms)
enableDiskCache	Whether the disk (level two) cache should be used or not	true
maximumSize	Maximum amount of chunks in memory cache	8192
expireAfterAccess	Time for a chunk in memory to expire	30000 (30s in ms)
maximumTaskQueueSize	Maximum number of simultaneously queued disk cache tasks	32768

obfuscation config section

This section contains arbitrarily named obfuscation config sections (e.g. obfsucation-overworld, obfsucation-nether, etc.). Each section can get assigned to multiple worlds but one world may only have one obfuscation section at a time. An obfuscation section contains a list of blocks that should get obfuscated, a list sections of blocks to use as replacement/obfuscation material and a list of worlds to obfuscate.

name	description	default value
enabled	Whether this obfuscation config should be enabled	true
worlds	List of world matchers to obfuscate
minY	Lowest block to obfuscate	-2032 (technical possible minimum)
maxY	Highest block to obfuscate	2031 (technical possible maximum)
layerObfuscation	When enabled uses one block type per Y layer per chunk (for further information click here)	false
hiddenBlocks	Set of blocks to be obfuscated
randomBlocks	List of randomBlocks sections which get used to replace the obfuscated blocks

world matchers

❗ Since version 5.2.0 (before this would have been a list of plain world names) Worlds can be matched in multiple ways. Here is list of all of them:

type	description	example
plain	A plain world name that would only match one specific world with the same name	world_the_end
simple glob	A simple glob pattern (only * wildcards are supported as of now) that would match all worlds that match the pattern	world*end
regex pattern	An arbitrary regex pattern (has to be prefixed with regex:) that would match all worlds that match the pattern	regex:world.+end

randomBlocks section

The randomBlocks sections can be arbitrarily named (e.g. section-global, section-stone, etc.). Each consists of a height limit and a list of weighted blocks. The height limit can used to fill certain parts of a world with different blocks based on their height (e.g. use deeplsate ores below y zero). The weight of a block determines how likely it is to get chosen as replacement block for an obfuscated block. If multiple sections target the same height then they will simply get merged. Here is a simple example:

randomBlocks:
  section-air:
    minY: -2032
    maxY: 2031
    blocks:
      minecraft:cave_air: 5
  section-stone:
    minY: -5
    maxY: 2031
    blocks:
      minecraft:stone: 15
  section-deepslate:
    minY: -2032
    maxY: 5
    blocks:
      minecraft:deepslate: 15

This example would create three different sections internally:

• section 1:
  • from y=-2032 to y=-5
  • blocks: cave_air=5(25%), deepslate=15(75%)
• section 2:
  • from y=-5 to y=5
  • blocks: cave_air=5(~14.2%), deepslate=15(~42,8%), stone=15(~42,8%)
• section 3:
  • from y=5 to y=2031
  • blocks: cave_air=5(25%), stone=15(75%)

Section 1 for example will only get used as replacement material for blocks between y -2032 and -5. The total weight of the section is 20 = 5(cave_air) + 15(deepslate) which results in cave_air having a 25% (5 / 20) chance to get selected and deepslate having a 75% (15 / 20) chance.

proximity config section

This section contains arbitrarily named proximity config sections (e.g. proximity-overworld, proximity-nether, etc.). Each section can get assigned to multiple worlds but one world may only have one proximity section at a time. A proximity section contains a list of blocks that should be hidden, a list sections of blocks to use as replacement/obfuscation material and a list of worlds to obfuscate. As well as a visibility distance and a boolean to enable a fast look at block check.

❗ Since version 5.2.2 The useBlockBelow obfuscation mode will replace proximity blocks with the next valid block (valid block is a block that wouldn't be obfuscation if placed at the proximity blocks location) from below the proximity block. This should help the obfuscation to blend better into the environment.

name	description	default value
enabled	Whether this proximity config should be enabled	true
minY	Lowest block to proximity hide	-2032 (technical possible minimum)
maxY	Highest block to proximity hide	2031 (technical possible maximum)
worlds	List of world matchers to proximity hide
distance	Maximum distance between a player and a hidden block in order for it to get deobfuscated	24
frustumCulling	For more info see: What is frustum culling and how does it work?
├─ enabled	Whether the frustum culling should be enabled or not	true
├─ minDistance	Minimum distance between player and block to be affected by frustum culling. Every block closer than this distance will ignore frustum culling	3
└─ fov	The camera FOV used for the view frustum	80
rayCastCheck	For more info see: What is ray cast checking?
├─ enabled	Whether ray cast checking should be enabled or not	false
└─ onlyCheckCenter	If enable will decrease accuracy slightly but improve performance of ray cast checking because fewer rays are casted	false
useRayCastCheck	Whether the player should be looking at a hidden block in order for it to get deobfuscated. (this function has big performance problems)	false
useBlockBelow	Enables the use block below obfuscation mode	true
hiddenBlocks	Set of blocks to proximity hide
randomBlocks	List of randomBlocks sections which get used to replace the proximity hidden blocks

proximity block options

Every block type can have his own constraints which are described in this section. The constraints include the blocks hide condition which is explained below and the useBlockBelow options which enables the useBlockBelow obfuscation mode.

name	description	default value
minY	Lowest block to proximity hide	-2032 (technical possible minimum)
maxY	Highest block to proximity hide	2031 (technical possible maximum)
useBlockBelow	Enables the use block below obfuscation mode	true

Here is an example for hiddenBlocks in a proximity config.

hiddenBlocks:
  chest: {}
  trapped_chest: {
    minY: 64
    maxY: 2031
  }

The block chest has the default height limit and will always be proximity hidden but the trapped_chest will only be proximity hidden above a y value of 64 (inclusive).
