MoreSparkles 1.3.0 (Cobblemon 1.8.0 / Minecraft 1.21.1)

MoreSparkles is no longer just a shiny booster. This release rebuilds the mod from the ground up and adds nine new boost types, a matching set of charms, Discord webhook announcements for boosts, and Placeholder API support.

[!WARNING] This update breaks existing configs and saved data. Back up config/MoreSparkles/ before you update, and read the migration notes below.

✨ New boost types

Boosts now have a type. Every command, boost area, charm and placeholder works with each of these types:

Type	What it boosts
SHINY	Shiny odds (the existing boost)
EXPERIENCE	Experience gained in battle
HIDDEN_ABILITY	Chance that wild spawns have their Hidden Ability
EV	EVs gained
IV	IV quality of Pokémon you catch, hatch or revive from fossils
BERRY	Berry harvest yield
CATCH_RATE	Catch rate
MARK	Chance of a mark on Pokémon you catch, hatch or revive from fossils
ALPHA	Alpha spawn chance
SPAWN_BUCKET	Odds of uncommon, rare and ultra-rare spawn buckets

Each player can run one active boost per type at a time, with a separate queue for each type.

🍀 New charms

Nine new charms, each with its own texture, join the Shiny Charm:

• Exp Charm (Experience)
• Veiled Charm (Hidden Ability)
• Effort Charm (EV)
• IV Charm (IV)
• Berry Charm (Berry)
• Catching Charm (Catch Rate)
• Mark Charm (Mark)
• Alpha Charm (Alpha)
• Bucket Charm (Spawn Bucket)

In items.json you can set each charm's boost type, multiplier and lore. The charms also have their own creative tab.

📣 Discord webhooks

MoreSparkles can post boosts to a Discord channel. The embed updates while the boost runs, and by default it is deleted when the boost ends. Set it up under webhook_settings in config.json:

"webhook_settings": {
  "enabled": false,
  "url": "https://discord.com/api/webhooks/your_webhook_url",
  "update_rate_seconds": 30,
  "delete_when_boost_ends": true
}

🧩 Placeholder API support

When Placeholder API is installed, the following placeholders are registered under the moresparkles: namespace. Placeholder API is optional.

Server: base_shiny_rate, base_bucket_chance, base_alpha_bucket_chance

Player: player_shiny_rate, player_hidden_ability_chance, player_iv_strength, player_bucket_chance, player_alpha_bucket_chance, and player_<type>_multiplier for each boost type, using the lowercased type name (for example player_shiny_multiplier, player_experience_multiplier or player_spawn_bucket_multiplier)

messages.json also has many new built-in placeholders for boosts (boost_multiplier, boost_duration, boost_time_remaining, boost_type) and boost areas (boost_area_name, boost_area_type, boost_area_multiplier).

⚙️ New config options

• pause_player_boosts_on_shutdown / pause_global_boosts_on_shutdown: keep the remaining boost time when the server restarts.
• experience_booster_ignores_candy / experience_booster_ignores_sidemod_source: stop the Experience boost from multiplying candy or experience from other mods.
• ev_booster_ignores_vitamins / ev_booster_ignores_sidemod_source: the same for the EV boost.
• hidden_ability_booster_base_chance: the base Hidden Ability chance that the multiplier scales (default 0.05).
• iv_booster_strength_constant: how strongly the IV boost shifts IVs upward.
• persistent_data_key_blacklist: skip boosts on Pokémon that carry certain persistent data keys (by default, the IV boost skips raid Pokémon).

Boost areas now take a boost_type and a display_name.

🛠️ Changes & fixes

• The mod was fully refactored: commands, config loading, player data and boost handling were rewritten.
• Missing keys in config files are now filled in with defaults automatically instead of breaking the file.
• Boost type names in config files are now case-insensitive.
• Global boosts are now saved in their own global_boosts.json file instead of in config.json.
• Many other bug fixes.
• Now requires Cobblemon 1.8.0 or newer.

⚠️ Breaking changes / migration

• The command syntax changed. Boosts now take a type as the first argument:

  /sparkles boost start <type> <multiplier> <duration> <seconds|minutes|hours|days> <players|global>
  

  The old multiplier cap tied to the Cobblemon shiny rate is gone.
• /sparkles boost stop and /sparkles clear-queue also take a type: /sparkles boost stop <type> <players|global> and /sparkles clear-queue <type> <players|global>. check-rate takes a type too: /sparkles check-rate <type> [player].
• Permission rename: sparkles.status, sparkles.status.global and sparkles.status.others are now sparkles.boost.status, sparkles.boost.status.global and sparkles.boost.status.others.
• items.json: the top-level shiny_charms key is now charms, and each charm needs a boost_type. Delete the file or update it by hand.
• messages.json was rewritten with many new messages. Regenerating it is recommended.
• Player data is now saved in config/MoreSparkles/players/ instead of playerdata/. Old player boosts and queues are not carried over.
• Active and queued global boosts stored in the old config.json are not carried over.
