Cobblemon Shiny Days

Choose days of the week to increase shiny odds for either all Pokémon or specific Pokémon, giving your server events similar to Community Days in Pokémon GO.

Dependencies

Cobblemon - Modrinth / Curseforge

Fabric Language Kotlin (for Fabric servers) - Modrinth / Curseforge

Features

  • Choose which days to increase shiny rates
  • Increase shiny odds for all spawns or only specific Pokémon
  • Broadcasts a message at a customisable interval to remind players what shiny rates are currently increased
  • /shinyday command to check currently boosted shiny rates

Installation

Place the .jar file in your /mods folder, and restart the server.

Configuration

The configuration has 5 customisable options

  • "species" : which Pokémon will have increased rates (can use "ALL" to increase odds of all Pokémon)
  • "labels" : Pokémon with these labels will have their shiny rates increased ("legendary", "gen1", "gen2" etc.)
  • "types" : Pokémon with these types will have their shiny rates increased ("water", "fire" etc.)
  • "days" : which days to apply the specified rates to the specified Pokémon
  • "multiplier" : how much to multiply odds by (uses the shiny rates in your Cobblemon config as a base rate, then adds this modifier) e.g. Cobblemon shiny rate is 1/8192, a multiplier of 2.0 will make the rate 1/4096
  • "broadcastInterval" : how often to send the broadcast (in seconds) letting players know which Pokémon have increased shiny rates.

Example Config

[
  {
    "species": ["Pikachu", "Bulbasaur", "Charmander", "Squirtle"],
    "labels": ["legendary", "mythical"],
    "types": ["normal"],
    "days": ["Saturday", "Sunday"],
    "multiplier": 5.0,
    "broadcastInterval": 300
  },
  {
    "species": [],
    "labels": ["gen1"],
    "types": ["water"],
    "days": ["Monday"],
    "multiplier": 2.0,
    "broadcastInterval": 300
  },
  {
    "species": [],
    "labels": ["gen2"],
    "types": ["fire"],
    "days": ["Tuesday"],
    "multiplier": 2.0,
    "broadcastInterval": 300
  },
  {
    "species": [],
    "labels": ["gen3"],
    "types": ["grass"],
    "days": ["Wednesday"],
    "multiplier": 2.0,
    "broadcastInterval": 300
  },
  {
    "species": [],
    "labels": ["gen4"],
    "types": ["psychic"],
    "days": ["Thursday"],
    "multiplier": 2.0,
    "broadcastInterval": 300
  },
  {
    "species": [],
    "labels": ["gen5"],
    "types": ["steel"],
    "days": ["Friday"],
    "multiplier": 2.0,
    "broadcastInterval": 300
  }
]

The config above would work as follows

Saturday and Sunday - Pikachu, Bulbasaur, Charmander, Squirtle, Normal-type, legendary and mythical Pokemon have 5x shiny rates

Monday - All Gen 1 & Water-type Pokemon have 2x shiny rates

Tuesday - All Gen 2 & Fire-type Pokemon have 2x shiny rates

Wednesday - All Gen 3 & Grass-type Pokemon have 2x shiny rates

Thursday - All Gen 4 & Psychic-type Pokemon have 2x shiny rates

Friday - All Gen 5 & Steel-type Pokemon have 2x shiny rates
