Help with configured features in forge (trying to spawn my flower into the world)

[diggydwarff]

Hello!

I am posting since I am at the end of the road in terms of googling this solution and/or pouring through github projects.
As the title suggests, I am trying to spawn my custom flower into the overworld into existing biomes, nothing crazy just a flower block spawned into the world.

I added an entry into forge/biome_modifier called add_dreamcap_mushroom.json. It is as follows:

{ "type": "forge:add_features", "biomes": [ , "minecraft:plains", "minecraft:jungle", "minecraft:birch_forest", "minecraft:sparse_jungle", "minecraft:forest" ], "features": "herbalistmod:dreamcap_mushroom_patch", "step": "vegetal_decoration" }

 

I have a directory worldgen/configured_feature with dreamcap_mushroom_patch.json as follows:
 

{
  "type": "minecraft:random_patch",
  "config": {
    "feature": {
      "feature": {
        "type": "minecraft:simple_block",
        "config": {
          "to_place": {
            "type": "minecraft:simple_state_provider",
            "state": {
              "Name": "herbalistmod:dreamcap_mushroom_block"
            }
          }
        }
      },
      "placement": [
        {
          "type": "minecraft:block_predicate_filter",
          "predicate": {
            "type": "minecraft:matching_blocks",
            "blocks": "minecraft:air"
          }
        }
      ]
    },
    "tries": 32,
    "xz_spread": 7,
    "y_spread": 3
  }
}

 

I have a directory worldgen/placed_feature with dreamcap_mushroom_patch.json as follows:

{
  "feature": "herbalistmod:dreamcap_mushroom_patch",
  "placement": [
    {
      "type": "minecraft:count",
      "count": 2
    },
    {
      "type": "minecraft:in_square"
    },
    {
      "type": "minecraft:heightmap",
      "heightmap": "WORLD_SURFACE_WG"
    },
    {
      "type": "minecraft:biome"
    }
  ]
}

 

As far as I know, these are the only files I need in order to generate blocks, etc into the world, yet despite this I have made tons of worlds searching high and low and my block is nowhere to be found.
Am I doing something wrong here or missing something obvious? Thanks in advance!

SOLVED! I ended up fixing this after a fresh night of sleep and cloning the forge repo and looking through that.

I had to add a BiomeModifier class to my mod, see this file here for assistance: MinecraftForge/src/test/java/net/minecraftforge/debug/world/BiomeModifierTest.java at 1.20.1 · MinecraftForge/MinecraftForge (github.com)
