Raid Den Spawning

Raid Dens are spawned as a Placed Feature (like Trees, Bushes, etc.) and can be configured using a data pack.

Modifying Spawns

You can modify the spawn rate of raid dens by editing this file in a data pack.

data/cobblemonraiddens/worldgen/placed_feature/raid_den_placed.json
{
  "feature": "cobblemonraiddens:raid_den",
  "placement": [
    {
      "type": "minecraft:rarity_filter",
      "chance": 256       // 1 in 256 chance of spawning
    },
    {
      "type": "minecraft:in_square"
    },
    {
      "type": "minecraft:heightmap",
      "heightmap": "MOTION_BLOCKING"
    },
    {
      "type": "minecraft:biome"
    }
  ]
}

Dimensions

Raid den spawns are determined using the biome tag #cobblemonraiddens:raid_spawnable.

data/cobblemonraiddens/tags/worldgen/biome/raid_spawnable.json
{
  "values": [
    "#minecraft:is_overworld"          // Default is overworld only
  ]
}

Configuration

The default behaviour of raid dens can be configured in the common config. See Configuration. Note that for cycle mode, only newly generated raid dens will reflect the changes made.
