Difficulty: Beginner

The Random Spawns system allows you to make your custom MythicMobs spawn in your worlds, at random! You can fine tune these spawns using many options and conditions, to make them spawn however you want them to!

There are 2 actions you can use when creating your spawn, ADD and REPLACE. Using replace will make MythicMobs overwrite vanilla mob spawns, this means there will be less vanilla mobs spawning, and you will have less control over it. Add on the other hand, generates spawn points along side vanilla spawn points, meaning it doesnt affect vanilla spawns, and you have more control.

When using add you must enable the GenerateSpawnPoints setting in /plugins/MythicMobs/config/config-spawning.yml and you must be in Survival mode or Adventure mode for mobs to spawn.

In this guide we will be using the ADD action since it is generally the better option.

Your Random Spawns go in the /plugins/MythicMobs/RandomSpawns folder and can also be put in subfolders for better organization. You can also create a RandomSpawns folder in a pack

Basic Setup

The basic setup of a RandomSpawn includes a few settings.

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether

In this basic example, we are making our mob SkeletonKing spawn with a 10% chance in our worlds called world and world_nether.

• Action: ADD we are using the ADD action to generate spawn points.
• Type: SkeletonKing the Internal Name of the MythicMob we are spawning.
• Chance: 0.1 chance is a percentage out of 1, so 0.1 is 10%
• Priority: 10 If we have multiple randomspawns and 2 are chosen to spawn at the same location, the one with the higher priority will spawn.
• Worlds: world,world_nether the mob will only spawn in these worlds, on a basic server setup this is the overworld and nether.

Biomes

We can go further and specify the biomes our mobs spawn in too! We can do this with the Biomes option. We can add just 1 or a list of multiple biomes.

Biomes uses the Spigot Biome Names

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether
  Biomes: JUNGLE,FOREST,SOUL_SAND_VALLEY

In this example our mob can spawn in the worlds world and nether and only in the biomes JUNGLE FOREST and SOUL_SAND_VALLEY

Position Type

When using the ADD action you can set a Position Type, this tells mythic if the mob should be spawned on land or in water.

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether
  Biomes: JUNGLE,FOREST,SOUL_SAND_VALLEY
  PositionType: LAND

Now our SkeletonKing will only spawn on land and not in oceans and rivers.

Level

If you use the Levels system and want your mobs to spawn with a specific level, you can set that too.

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Level: 4
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether

This would spawn our mob with a level of 4.

Adding Conditions

We can add almost any Condition to our random spawn to further decide how we want our mobs to spawn. We can typically only use Entity and Location type conditions, the Replace action will check Entity conditions.

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether
  Biomes: JUNGLE,FOREST,SOUL_SAND_VALLEY
  Conditions:
  - night true
  - raining true

In this example we have added conditions to make our mob only spawn if its both night time, and raining. All the conditions in the list must be met for the mob to spawn.

Advanced Note

Using Composite Conditions you can setup conditions that would match one or the other but not both.

Limiting

You can use conditions to limit your mob spawns and allow only certain amounts of your mobs to spawn. The 2 most common ways to do this is using the MobsInRadius and MobsInChunk conditions.

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether
  Biomes: JUNGLE,FOREST,SOUL_SAND_VALLEY
  Conditions:
  - night true
  - raining true
  - mobsinchunk{a=<10} true
  - mobsinradius{t=SkeletonKing;a=<3;r=64} true

In this example we are allowing our SkeletonKing to spawn only if there is less than 10 of any mob in the chunk, and less than 3 SkeletonKings within a 64 block radius.

Scaling

This section only applies if your mobs have Level Modifiers setup.

We can use WorldScaling to determine if the mobs level should be increased based on the distance. By default this is enabled, so if your mobs have level modifiers, and you don't want them to increase in level based on the world scaling, set this to false.

SkeletonKingSpawn:
  Action: ADD
  Type: SkeletonKing
  Chance: 0.1
  Priority: 10
  Worlds: world,world_nether
  UseWorldScaling: false
