MobLimiter
Version 2 of MobLimiter, featuring three configurable Limiter engines that control the mob population in different ways.
While the original version of MobLimiter was primarily designed to cull mobs on chunk unload, with limited support to prevent new spawns in real time, MobLimiter 2 is designed from the ground up to be more proactive about managing the spawning and removal of entities. The Limiters are:
-
Age: Mobs can be configured to have a maximum lifespan (in ticks) that results in the entity being killed and dropping its items after the limit is reached. ("Special" mobs are exempt.) MobLimiter will try to not kill breeding pairs of farm animals if it can, by not killing farm animals if there would be less than two in the chunk.
-
Spawning: MobLimiter can be configured to limit the spawning of new mobs in real time, checking the number of the applicable mob type in a "view distance" (as a chunk radius) as well as in an individual chunk and blocking the addition of extra mobs beyond the limit.
-
Chunk Unload: The chunk-unload culling feature of MobLimiter 1.x is still available, if its use is desired.
Configuration
General Settings
radius: The "view distance" to check for mobs, as a chunk radius (e.g. 3 would be a 7x7 area)breeding_ticks: Farm animal breeding cooldown in ticks (-1 to disable)growth_ticks: Ticks for a farm animal to grow up (-1 to disable)logblock: Enable LogBlock support.

Default Limits
The defaults block defines limits that will globally apply to any mob type that doesn't have an explicit override
defined in the limits block. (Undefined values fall back to -1, for disabled.) Specific mob limits inherit the
default block, with any defined fields overriding the value from defaults.
defaults:
age: 18000 #15 minutes in ticks
max: 200 #200 in "view distance"
chunk_max: 50 #50 in a single chunk
cull: 4 #cull mobs down to this maximum on chunk unload
age: Enable age limiting and remove the mob after a number of ticks. (e.g. 18000 for 15 minutes)max: The maximum number of a mob type to be allowed to spawn in a "view distance" defined byradius.chunk_max: The maximum number of a mob type to be allowed to spawn in a single chunk.cull: If set to a value other than-1, the number of mobs to not be removed on chunk unload.
Individual Mob Limits
The limits block allows you to specify limits that apply to individual mob types. These inherit the values defined in
defaults, overriding the values.
Mob types are named using their Bukkit EntityType string, with the exception of sheep, which are addressed in the form of sheep_white or sheep_red so they can be handled individually for farming purposes.
limits:
skeleton:
max: 100
chunkMax: 30
age: 12000
cow:
chunkMax: 75
age: 12000
horse:
age: -1
villager:
max: 200
chunkMax: 50
age: -1
Farm Animal Breeding Tweaks
The breeding_ticks and growth_ticks fields define how many ticks a farm animal will remain a baby and the breeding
cooldown, respectively. If your server is running at a full 20 ticks per second, a value of 400 for each would make
the respective values approximately 20 seconds.
If the value is set to zero, there will be no delay and the condition will be instantaneous. A value of -1 will disable tampering with vanilla breeding behavior.
This function only affects farm animals, and ignores other breedable entities like ocelots, wolves and villagers.
Special Mobs
MobLimiter will not remove any mobs that are deemed to be "special" in some way that may make their removal undesirable.
The criteria include:
-
Mobs with custom names, such as from a name tag
-
Tamed mobs
-
Elder guardians. (Regular guardians can be limited, but Elder ones won't be touched.)
-
Any mob that is holding an item, as it may have picked up a player's equipment.
LogBlock Integration
If LogBlock is running on the server, you can enable LogBlock integration by setting the logblock field to true in the
config file. When enabled, mob removals will be tracked as kills in LogBlock when MobLimiter performs a chunk unload
cull or age limit kill.
Age limit kills are logged with a weapon of watch and chunk unload culling uses gold sword, both using a "player"
name of MobLimiter.
