There are a few default spawners that come with Lycanites Mobs. If you want to edit a deafult spawner you must set “loadDefault” to false or delete it from the JSON otherwise your changes will be overwritten every time the game loads up, the same will also happen if you have invalid json.

This is designed to replicate the vanilla CREATURE random spawner which slowly spawns animals overtime. This is currently disabled by default while it's being tested but can be enabled if using another mod that breaks vanilla spawning.

This is designed to replicate the vanilla CREATURE chunk spawner which spawns peaceful mobs on newly generated chunks. This is currently disabled by default while it's being tested but can be enabled if using another mod that breaks vanilla spawning.

This is designed to replicate the vanilla MONSTER random spawner which spawns mobs in dark areas. This is currently disabled by default while it's being tested but can be enabled if using another mod that breaks vanilla spawning.

Spawns flying mobs randomly in the air in the Nether. Ignores biome, Nether only.

You can create as many custom spawners as you like, though if you add a lot of spawners with very high block search ranges and rapid ticks you could slow the game down, however you can use conditions to filter down when spawners should activate a lot and save on a good amount of performance. You could have 100 custom spawners but if their conditions means only 3 of them are actually running at the same time then the performacne should be great.

To create a new spawner, simply add your Spawner JSON file to the “config/lycanitesmobs/spawners” folder. You can use the command “/lm spawners reload” when in game to reload all spawners allowing you to test on the fly! There is also a “JSONSpawners” debug option in the lycanitesmobs-general.cfg file which will enable a lot of logging to the console if you need it, though errors should always show up in the log and shouldn't crash the game, instead the broken spawner is ignored.

Spawners are made up of 5 sections, the base Spawner properties, Spawn Conditions, Spawn Triggers, Spawn Locations and Mob Spawns.

You can always copy a default spawner and repurpose it instead of writing a new one from scratch too, just be sure to change the name or only one of the spawners will load!

You can also edit default mob events as well as add your own in “config/lycanitesmobs/mobevents”. See the Mob Events section for more info.

Each property uses a specific data type, please look up how JSON works if you don't know: Spawners JSON

There are several base properties, some are required, everything else has a default value.

This is a unique name for your spawner, try to avoid spaces and other special characters, names are not case sensitive so I recommend sticking to all lower case. Required.

This is a non-unique name used to assign this spawner to creature/group configs. For example the 'water' and 'water chunk' spawners both have a shared name of 'water' so that any creature configs that use the water spawner use both spawners. Optional.

This is only used by the default spawners and must be false or not present in the JSON to prevent the spawner from being overwritten when the game loads. You can simply leave it out of your custom spawners. Default false.

Set to true to use these spawner or false to disable it, needed for disabling default spawners and handy for custom spawners that you want to disable but not delete. Default true.

Determines how many Spawn Conditions must be met. If set to 0 or less then Spawn Conditions all are required. Default 0 (all).

Sets how many times any Spawn Trigger must activate (per player) before a wave is spawned. Please look at the Darkness Spawner to see this in action. Default 1.

You can add a chat message for specific Trigger counts, these can be lang file entries. Please look at the Darkness Spawner to see this in action. Default empty.

The trigger count for this message. Required.

The chat message to send to the player, this can be typed out in full here or can be a lang file key (recommended). Required.

Determines how a Spawn Location is chosen if there are more than one defined. Can be: “order” (first location that can find a spawn point), “random” (picks a random Spawn Loction and just uses that) or “combine” (gets spawn points from all Spawn Locations). Default “combine”.

The minimum amount of mobs to spawn each wave. Default 1.

The maximum amount of mobs to spawn each wave. If less than or equal to the minimum this is ignored so you don't need to set this for fixed mob counts. Default 1.

If true, this Spawner will ignore all mob dimension checks (not Spawn Condition checks), this bypasses the checks in Mob Spawn entries as well as Mob Configs. Default false.

If true, this Spawner will ignore all biome checks, this bypasses the checks in Mob Spawns and Mob Configs. This is recommended if your Spawner should never care about biome as it saves on checks for performance. Default false.

If true, this Spawner will ignore mob collision checks, this may cause mobs to become stuck and suffocate but is useful for smaller mobs, required Spawners that have a Block Break radius set (see blow) and good for noclip mobs (like the Phantom). Default false.

If true, this Spawner will ignore light level checks, this bypasses the checks in Mob Spawns and Mob Configs. This is recommended if your Spawner should never care about light levels as it saves on checks for performance. Default false.

If true, this Spawner will ignore group limit checks, this bypasses the checks in Mob Spawns and Mob Configs. This is recommended if your Spawner should never care about group limits as it saves on checks for performance. Default false.

The range of how far (in blocks) this Spawner should check for surrounding mobs of the same type for the group spawn limit, don't go too high with this and rapid spawners or you will get lag. Default 32.

If set to true, the Forge Can Spawn Event is fired but its result is ignored, use this to prevent other mods from stopping the spawn via the event. Default false.

If true, mobs spawned by this Spawner will not naturally despawn. Default false.

If true, actions caused by the spawner will attempt trigger additional spawners. Default true.

If true, this Spawner will act as enabled even if it can't find any mobs to spawn, useful if you just want to use trigger messages, etc. Default false.

If set, this is the name of the mob event that must be active, otherwise this Spawner is always active. Use this for mob event spawners. Default “” (empty).

If set, when a mob is spawned, blocks in the radius around the spawned mob will be destroyed (0 would break only the block the mob spawned at). Spawners like the Ore Spawner use this. Default -1 (no block breaking).

A list of Spawn Conditions that this Spawner will check. Default empty (Spawner will always work).

A list of Spawn Triggers that will attempt to start this Spawner. Default empty (Spawner will never start, so should have at least 1 Trigger to function).

A list of Spawn Location that this Spawner will use to get spawn positions from. Default empty (Spawner will never be able to Spawn anything so should have at least 1 Spawn Location).

A list of Mob Spawns that this Spawner will pick mobs to spawn from on top of mobs that have this Spawner's name as a Spawn Type in the configs. Default empty (Just use spawns added via the config).

Spawn Locations are used to decide where to place the newly spawned mobs relative to the Trigger Position (this is decided by the Trigger and is usually the player position or broken block position).

The minimum xyz range in blocks from the trigger position to spawn mobs from. This must be an array of 3 integers. Default [0, 0, 0].

The maximum xyz range in blocks from the trigger position to spawn mobs from. This must be an array of 3 integers. Default [0, 0, 0].

When multiple spawn positions are found, this determines how they are sorted before spawning mobs at them. Can be “random”, “near”, “far”. Default “random”.

Base can be used as a type for a simple location, be it random near the player or precisely on the trigger position. Block based Spawners such as the Ore Spawner use this with everything at default settings to spawn a mob where the block was destroyed.

The block type finds locations that are a specific block. The Lava and Fire Spawners use this. For larger areas such as those used by the Animal or Water Spawners, the Random Type is much more effcient and has additional features.

A list of blocks to filter by. Use block ids like “minecraft:air”. Default empty.

Determines if the blocks list is a blacklist or whitelist. Default “whitelist”.

If true, positions that can see the sky are allowed. Default true.

If true, positions that can not see the sky are allowed. Default true.

If set, this many of the spawnable blocks must be found. The fire spawner uses this so that it only spawns when there is a lot of fire blocks near each in one area. Default -1 (no cost).

If set (above 0), this is the amount of each block in the blocks list must be found. See the mineshaft spawner as an example where by default it requires 4 planks, rails and webs. Default: 0 (disabled).

This works the same as the Block Type but filters by Block Material instead of specific blocks. This uses the properties that the Block Type uses but with the materials property instead of blocks.

A list of block materials to filter by. Default empty.

This is a very efficient and more advanced location that works better for broader areas like on the world surface, in caverns, underwater, etc instead of specific areas like pockets of Lava or Ooze. This uses the properties that the Block Type uses with additional properties.

How many random positions to find. Try not to find more positions than the mob spawn limit of the Spawner as they are just unused it's just a waste of processing. Default 32.

If true positions require a solid walk-able block underneath rather than being able to float in the air/water. This is ideal for land based spawners as well as for spawning mobs on the bottom of the ocean, etc. For flying mobs you'll want this to be false or they'll all spawn on the ground. Default false.

This scales the x and z range values by this amount when on Easy or Peaceful Difficulty. Default 1.5.

This scales the x and z range values by this amount when on Normal Difficulty. Default 1.

This scales the x and z range values by this amount when on hard and above Difficulty. Default 0.5. Spawn Triggers Spawn Triggers are what make a Spawners start and are based on various game events ranging from random ticks to certain blocks being broken, etc.

Each type of Spawn Trigger has its own properties, some properties are shared mongst different types.

The type of Spawn Trigger this is, if the type is not recognised, then it is ignored. Can be one of the listed types below in lowercase, no space, Ex: “ore”

How much this influences the Spawner's trigger count by, usually just 1. If 0 this Trigger will instead completely reset the count, if negative it will reduce the count. See the Darkness Spawner for this in action. Default 1.

The Chance of triggering where 1 is 100%. Can be 0.0-1.0. Default 1.

A Spawn Trigger can also have it's own list of Trigger-specific Spawn Conditions that are only checked for this Trigger. See the Darkness Spawner for this in action. Default empty.

Determines how many Spawn Conditions must be met. If set to 0 or less then Spawn Conditions all are required. Default 0 (all).

This Trigger fires every world tick and is good for generic random spawners as well as timed spawners that spawn mobs all over the world. 20 ticks = 1 second.

How many ticks between trigger attempts. Default 400 (every 20 seconds).

If true, rather than every “tickRate”, it is instead when the world time is equal to the “tickRate” set, good for trigger at an exact time every world day. Default false.

This Trigger fires every player tick and is good for generic random spawners as well as timed spawners that revolve around each player. 20 ticks = 1 second.

How many ticks between trigger attempts. Default 400 (every 20 seconds).

The minimum distance the player must be away from the last tick position. Default -1 (ignored).

The maximum distance the player must be away from the last tick position. Default -1 (ignored).

If true, rather than every “tickRate”, it is instead when the world time is equal to the “tickRate” set, good for trigger at an exact time every world day. Default false.

This Trigger fires when certain blocks are broken by the player.

If true, only players can activate this Trigger, fake players are not counted as players. Default true.

If true, the Block Break event will activate this trigger. Default true.

If true, the Block Harvest event will activate this trigger. Default true.

If true, this Block Place event will activate this trigger. Default true.

A list of blocks to filter by. Use block ids like “minecraft:air”. Default empty.

Determines if the blocks list is a blacklist or whitelist. Default “whitelist”.

A list of block materials to filter by. Use the material name like “wood”. Default empty.

Determines if the block materials list is a blacklist or whitelist. Default “blacklist”.

How to react to blocks broken with or without silk touch. Can be: “ignore”, “require” or “deny”. Default: “ignore”.

The minimum fortune that the harvester must have. Default: -1 (ignore).

The maximum fortune that the harvester must have. Default: -1 (ignore).

This Trigger fires when ore blocks are broken by the player.

This type uses the same properties as the Block Type.

If true, ores (ore blocks that drop as blocks as well as coal and monster egg) will trigger, if false they wont. Default: true.

If true, gems (ore blocks that drop as items excluding coal and monster egg) will trigger, if false they wont. Default: true.

This Trigger fires when blocks that are part of a tree are broken by the player. This searches for log blocks and then searchs up and to the side for leaves blocks.

This type uses the same properties as the Block Type.

This Trigger fires when crop blocks are broken by the player. This searches for vines, planted farm plants like Wheat as well as Melon and Pumpkin stalks.

This type uses the same properties as the Block Type.

This Trigger fires when water and lava mix to form a solid block.

This type uses the same properties as the Block Type where the block to filter by is the block that is formed from mixing the water and lava (stone, cobblestone or obsidian). I later plan to make this more customisable.

This Trigger fires when the player attempts to use a bed at night. If the Trigger is successful (passess random chance, but does not check if a mob actually spawns), the player is stopped from sleeping.

This type uses the same properties as the Block Type where the block to filter by is the bed block that was used, handy for reacting to beds from other mods such as adding in 'safe beds'.

How long (in ticks) until this trigger can be started again, this is done per player. Default 1200 (10 minutes).

This Trigger fires when the player kills another mob.

A list of entity types to filter by, can be: “UNDEAD” (zombies, phantoms, etc), “UNDEFINED” (most mobs), “ARTHROPOD” (insects, arachnids, etc). Default empty.

Determines if the entity types list is a blacklist or whitelist. Default “whitelist”.

A list of entity ids to filter by, you can get a mob's id from the creature page, but it usually follows a pattern like: “mountainmobs.jabberwock” or “minecraft.zombie”, modded mobs may also work. Default empty.

Determines if the entity ids list is a blacklist or whitelist. Default “blacklist”.

This Trigger fires when the player fishes up an item. This has no special properties of its own.

This Trigger fires when an explosion occurs. Usually there is no player object involved with this so any player conditions will make the spawner fail.

How strong the explosion has to be to trigger this spawner. Default 4 (TNT's strength).

A list of entity types to filter by for explosion starters, can be: “UNDEAD” (zombies, phantoms, etc), “UNDEFINED” (most mobs), “ARTHROPOD” (insects, arachnids, etc). Default empty.

Determines if the entity types list is a blacklist or whitelist. Default “whitelist”.

A list of entity ids to filter by for explosion starters, you can get a mob's id from the creature page, but it usually follows a pattern like: “mountainmobs.jabberwock” or “minecraft.zombie”, modded mobs may also work. Default empty.

Determines if the entity ids list is a blacklist or whitelist. Default “blacklist”.
