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
