📦 Datapack Integration (Fusion Chamber)

For Cobblemon Poké Fusion 2.0.0

Datapack creators can fully add custom fusion recipes to the Fusion Chamber using the below structure.

📁 Folder Structure

data/<namespace>/fusions/" then put any json file

for example in my mechamew2 addon for testing purposes i did

\datapacks\mechamew2.zip\data\cobblemon\fusions\bazinga.json

this doesnt interfere with base config and you can name the .json whatever you want

🔒 Input Constraints

Fusion recipes can now lock specific aspects and level ranges for input Pokémon.

This allows you to require things like:

• Only shiny Pokémon
• Specific level ranges

💡 Example

{
  "id": "vulpix_triple",
  "inputs": [
    {
      "side": "x1",
      "speciesId": "cobblemon:vulpix",
      "aspects": ["shiny"],
      "minLevel": 20,
      "maxLevel": 40
    },
    {
      "side": "y1",
      "speciesId": "cobblemon:vulpix",
      "aspects": ["shiny"],
      "minLevel": 20,
      "maxLevel": 40
    },
    {
      "side": "z1",
      "speciesId": "cobblemon:vulpix",
      "aspects": ["shiny"],
      "minLevel": 20,
      "maxLevel": 40
    }
  ],
  "results": [
    {
          "id": "ninetales",
          "displayName": "ninetales",
          "speciesId": "cobblemon:ninetales",
          "spec": "ninetales shiny=true",
          "weight": 100,
          "form": "",
          "ivs": {}
        }
      ]
    }

👉 This fusion will only work if:

• All Vulpix are shiny and between level 20-40

{
      "id": "vulpix_triple_random",
      "inputs": [
        {
          "side": "x1",
          "speciesId": "cobblemon:vulpix",
          "aspects": ["shiny", "alolan"],
          "minLevel": 20,
          "maxLevel": 40
        },
        {
          "side": "y1",
          "speciesId": "cobblemon:vulpix",
          "aspects": ["shiny", "alolan"],
          "minLevel": 20,
          "maxLevel": 40
        },
        {
          "side": "z1",
          "speciesId": "cobblemon:vulpix",
          "aspects": ["shiny", "alolan"],
          "minLevel": 20,
          "maxLevel": 40
        }
      ],
  "results": [
    {
          "id": "ninetales",
          "displayName": "ninetales",
          "speciesId": "cobblemon:ninetales",
          "spec": "ninetales alolan=true shiny=true",
          "weight": 100,
          "form": "",
          "ivs": {}
        }
      ]
    }

👉 This fusion will only work if:

• All Vulpix are shiny, alolan and between level 20-40

📊 Dynamic Level Scaling

Fusion results can now inherit levels dynamically.

• If no level is defined in inputs or results
  👉 The result level is calculated from the Pokémon placed in the chamber

All fusions are defined in:

config/cobblemonpokefusion/fusions.json

Each recipe contains:

• Inputs → Pokémon required
• Results → Possible outcomes

{
  "id": "starter_duo_fire_water",
  "inputs": [
    { "speciesId": "cobblemon:charmander" },
    { "speciesId": "cobblemon:squirtle" }
  ],
  "results": [
    {
      "speciesId": "cobblemon:charizard",
      "level": 16
    }
  ]
}

👉 Charmander + Squirtle → Charizard

Some fusions require Pokémon to be placed in a specific order using side values like x1, y1, z1.

{
  "id": "starter_trio_kanto",
  "inputs": [
    { "side": "x1", "speciesId": "cobblemon:bulbasaur" },
    { "side": "y1", "speciesId": "cobblemon:charmander" },
    { "side": "z1", "speciesId": "cobblemon:squirtle" }
  ],
  "results": [
    {
      "id": "venusaur",
      "speciesId": "cobblemon:venusaur",
      "weight": 33
    },
    {
      "id": "charizard",
      "speciesId": "cobblemon:charizard",
      "weight": 33
    },
    {
      "id": "blastoise",
      "speciesId": "cobblemon:blastoise",
      "weight": 33
    }
  ]
}

👉 This will only work if:

• Bulbasaur is placed in first
• Charmander is palced in second
• Squirtle is placed in third

Any other order will not work unless another recipe is defined.

⚖️ Weight System

When multiple results exist, the mod uses a weight system to decide which result you get.

• Each result has a weight value
• The higher the weight, the higher the chance

🧮 Example:

Venusaur → weight 33  
Charizard → weight 33  
Blastoise → weight 33  

Total weight = 99

👉 Each result has roughly:

• ~33% chance each

💡 How to Use Weights

• Equal weights → equal chance
• Higher weight → more common result
• Lower weight → rarer result

Example:

Common Pokémon → weight 80  
Rare Pokémon → weight 20  

👉 Result:

• 80% chance common
• 20% chance rare

🧠 Summary

• Use speciesId only → order doesn't matter
• Use side (x1, y1, z1) → order matters
• Use weight → controls randomness

This gives you full control over how every fusion behaves.

⚖️ Weights & Random Results

Some fusions don’t give a fixed result — instead, they use a weight system.

Each result has a weight value, which determines how likely it is to be chosen.

🎲 Example: Starter Trio Fusion

• Bulbasaur + Charmander + Squirtle

Possible results:

• Venusaur → weight 34
• Charizard → weight 33
• Blastoise → weight 33

🔢 How It Works

Total weight = 100

• Venusaur ≈ 34% chance
• Charizard ≈ 33% chance
• Blastoise ≈ 33% chance

👉 You will get one of the three final evolutions randomly

⚙️ Custom Results

Fusion results can define:

• Level
• IVs
• Special forms
• Weight
• Exact Pokémon

🧪 Custom Forms & Mod Compatibility

Fusion results can also use the spec field to apply custom forms, flags, or properties.

This means the mod works seamlessly with other mods that add special forms.

💡 Example

If you have a mod like Lost Lore installed, you can use its forms directly:

"spec": "lugia shadow=true level=80"

👉 Creates a Shadow Lugia

🧪 Fusions Included

• Charmander + Squirtle → Wartortle / Charmeleon / Charizard (different weights)
• Bulbasaur + Charmander + Squirtle → Random final evolution (Venusaur / Charizard / Blastoise)
• Zekrom + Reshiram + Kyurem → Original Dragon (Kyurem Origin Form)
• Zapdos + Articuno + Moltres → Thufizer
• Mew + Mew + Mew → Ditto Perfect IV
• Ursaluna + Ursaluna + Ursaluna → Bloodmoon Ursaluna
• Ditto + Ditto + Ditto → Random Pokémon Random IVs

⚠️ Addon Compatibility Note

You do not need the Thufizer or Original Dragon addons for this mod to work.

• The mod will run perfectly fine without them
• If those addons are not installed:
  • The Original Dragon fusion will default to Kyurem
  • The Kanto Birds fusion will default to a random Pokémon

I have tested mod on default cobblemon modpack.

📌 Final Notes

• This mod is fully configurable, allowing you to create any fusion you want through the config
• You can freely modify, expand, and customize all recipes
