• block (required): The block ID that triggers the spawn

  • Format: namespace:block_id
  • Examples: minecraft:wheat, minecraft:sunflower, minecraft:stone, somemod:magical_crop
  • Works with any block type (crops, flowers, ores, grass, etc.)

• cobblemon (required): The Cobblemon species to spawn

  • Format: cobblemon:species_name
  • Examples: cobblemon:oddish, cobblemon:bulbasaur, cobblemon:chikorita

• odds (required): The chance of spawning (0.0 to 1.0)

  • 0.05 = 5% chance
  • 0.1 = 10% chance
  • 1.0 = 100% chance (always spawns)

• required_age (optional): The specific growth stage required

  • If omitted, any growth stage will trigger the spawn (or blocks without age properties will always trigger)
  • Most vanilla crops have ages 0-7, with 7 being fully grown
  • Beetroots use 0-3, with 3 being fully grown
  • The system automatically detects properties named "age", "stage", or any integer property
  • For blocks without age/stage properties (stone, grass, etc.), this parameter is ignored

• min_level (optional): The minimum level for the spawned Cobblemon (default: 5)

  • Must be at least 1
  • Example: 5 for level 5

• max_level (optional): The maximum level for the spawned Cobblemon (default: 5)

  • Must be greater than or equal to min_level
  • Example: 10 for up to level 10
  • The actual level will be randomly chosen between min and max (inclusive)

• shiny_odds (optional): The chance of the spawned Cobblemon being shiny (0.0 to 1.0, default: 0.0)

  • 0.01 = 1% chance to be shiny
  • 0.1 = 10% chance to be shiny
  • 1.0 = 100% chance (always shiny)

• aspects (optional): Aspects to apply to the spawned Cobblemon

  • Format options:
    • Array of strings: ["shiny", "galarian"] for simple aspects
    • Array with objects: ["shiny", {"pattern": "kanto"}] for mixed simple and multi-choice aspects
    • Object: {"pattern": "kanto", "shiny": true} for multi-choice aspects with boolean flags
  • Multi-choice aspects (aspects with options) use the format {"aspect_name": "option_value"}
    • Example: {"pattern": "kanto"} becomes pattern=kanto
    • Example: {"bloom": "leaf"} becomes bloom=leaf (for custom modded aspects)
  • Boolean aspects in object format: {"shiny": true} adds the aspect, {"shiny": false} omits it
  • Aspects modify the appearance or properties of Cobblemon and can trigger form changes
  • When an aspect corresponds to a form (e.g., "galarian", "alola", "hisuian"), the Pokemon will be created with that form and all its associated stats/types/moves
  • See Cobblemon documentation for available aspects and their options

• ivs (optional): Individual Values for the spawned Cobblemon's stats (0-31 for each stat)

  • Format: Object with stat names as keys
  • Available stats: hp, attack, defense, special_attack, special_defense, speed
  • Values are clamped between 0 and 31
  • If omitted, IVs are randomly generated (default behavior)
  • Fixed value format: "hp": 31 - Always spawns with exactly 31 HP IV
  • Range format: "hp": [20, 31] - Spawns with random HP IV between 20-31 (inclusive)
  • Example: {"hp": 31, "attack": [25, 31], "speed": 31} for perfect HP and Speed, but variable Attack

• cancel_drops (optional): Prevent the block from dropping its normal loot when a Cobblemon spawns (default: false)

  • Set to true to cancel all block drops when the Cobblemon spawns
  • The block will still be destroyed, but no items will drop
  • Automatically detects and cancels drops for connected blocks (e.g., both halves of a sunflower)
  • When false, players get both the Cobblemon spawn and normal block drops

• tool_required (optional): Restrict which tools/items can trigger the spawn (default: any item)

  • If omitted, any item (including bare hands) can trigger the spawn
  • Single item format: "minecraft:diamond_hoe" - Only diamond hoes trigger the spawn
  • Array format: ["minecraft:diamond_hoe", "minecraft:netherite_hoe"] - Any of these tools trigger the spawn
  • Use full item IDs with namespace (e.g., "minecraft:diamond_hoe", "farmersdelight:minced_beef")
  • Works with modded items - any item registered in the game can be specified
  • Useful for requiring specific tools for rare spawns (e.g., only diamond pickaxe for rare ore spawns)
  • The player must be holding the required item in their main hand when breaking the block

• Use lower odds (0.01-0.1) for rare Cobblemon to keep them special
• Match thematic Cobblemon to blocks (grass types for wheat, rock types for stone, etc.)
• Consider using different odds for different growth stages on age-based blocks
• Use level ranges to add variety (e.g., min_level: 5, max_level: 15)
• Keep shiny odds low (0.001-0.01) to maintain their rarity
• Combine high shiny odds with low spawn odds for "jackpot" encounters
• Use aspects sparingly for special encounters
• For multi-choice aspects (pattern, form, bloom, etc.), use object format: {"pattern": "kanto"} - this automatically adds the = separator
• You can mix aspect formats: ["shiny", {"pattern": "kanto"}] works perfectly
• Use perfect IVs (31) for ultra-rare encounters or legendary Pokemon
• Use IV ranges like [25, 31] to guarantee high IVs without being perfect (adds variety)
• Mix fixed and range IVs for interesting combinations (e.g., perfect speed but variable attack)
• Set cancel_drops: true if you want the Cobblemon to replace the block drops entirely
• cancel_drops: true will prevent drops from both halves of 2-tall blocks when a Cobblemon spawns
• Leave cancel_drops: false (default) if you want players to get both Cobblemon and block items
• You don't need to specify all IVs - only set the ones you want to be fixed (others will be random)
• For 2-tall blocks: breaking either half works correctly - the system processes based on the bottom half automatically
• Use tool_required to create "exclusive" spawns that require specific tools (e.g., rare Pokemon only from diamond tools)
• Combine tool_required with low odds and high levels for ultra-rare "jackpot" encounters
• tool_required works with any item, not just tools - you can require a specific item in hand to trigger spawns
• Test your configurations in creative mode first
• Use /reload to reload configurations without restarting
