Worlds populators

Worlds populators allow you to spawn custom blocks under the surface of the world. They are mostly used for ores and decoration blocks.

Example: two populators

This code allows you to tell ItemsAdder to generate the block myitems:custom_block in the world named world and replace only block of types STONE, DIRT, ANDESITE, GRANITE, COBBLESTONE, GRAVEL and only in biome PLAINS.

It will spawn 1 vein made of 3 blocks in each chunk.

vein_blocks, chunk_veins, chunk_chance

I suggest you to read values from the blocks.yml file I created in the ItemsAdder folder. Don't put too high values or the server could lag. Take my values as example.

chunk_veins: number of veins to be spawned in the chunk vein_blocks: number of blocks in each ore vein (or the vein size) chunk_chance: chance of that generation to happen in the chunk. You should set it to 100 to normal ores and lower it down for more rare ores.

Old ItemsAdder versions before 3.1.6 used these properties instead: chunk_veins -> iterations

vein_blocks -> amount

chunk_chance -> chance

Biomes

You can remove this option and the plugin will spawn ores in every biome.

  custom_block:
    block: myitems:custom_block
    worlds:
    - world
    replaceable_blocks:
    - STONE
    - DIRT
    - ANDESITE
    - GRANITE
    - COBBLESTONE
    - GRAVEL
    chunk_chance: 70.0
    max_height: 45
    min_height: 25
    vein_blocks: 6
    chunk_veins: 1

Replaceable blocks

You can remove this option and the plugin will spawn ores replacing every block instead of checking if it can be replaced.

  custom_block:
    block: myitems:custom_block
    worlds:
    - world
    chunk_chance: 70.0
    max_height: 45
    min_height: 25
    vein_blocks: 6
    chunk_veins: 1
