About this project
What does Gaatsumon add?
GaatsuMon
A Cobblemon add-on for Fabric that adds new Poké Balls, rare variants, a Trainer Card, a player economy, a shared Hunt Board and powerful tools for server operators.
Requires Minecraft 1.21.1, Fabric, Fabric API and Cobblemon 1.8.4. Install on both the client and the server.
Poké Balls
- Amethyst Ball – a crystal-lidded ball in the style of an amethyst geode.
- 20 ore balls – coal, copper, iron, gold, redstone, lapis, diamond, emerald, quartz and netherite, plus a ball for each Cobblemon evolution stone (dawn, dusk, fire, ice, leaf, moon, shiny, sun, thunder and water).
- Every ball has its own icon, held and thrown model, and party icon, and works like a native Cobblemon ball. Higher-tier ores catch better.
- Craft one with four of the ore's item around a Poké Ball.
- Their own creative tab: GaatsuMon: Poké balls.
Rare variants
- Purple/Black and Halloween Axew, Fraxure and Haxorus, found in the wild at 1 in 32,768 per spawn, which is four times rarer than a shiny.
- Axew can sit on your shoulder and Haxorus can be ridden.
- Purple and black sparkles for the variants, and a Shiny Grace mechanic.
Trainer Card
Every trainer gets a personal card with a unique ID, shown in a screen drawn entirely by the mod.
- Tracks Pokédex progress, catches, shinies, battle wins, win streaks, eggs hatched, playtime, Pokémon of each type caught, and PvP victories and losses.
- 5 stars set your card tier, from Plain up to Black.
- 45 themes, unlockable titles, a bio line, three showcase Pokémon and 8 badges.
- Operator-granted roles such as Champion, Frontier Brain, Gym Leader and Elite Four for every type, or any custom text.
- Sneak + right-click another player to view their card.
- Your equipped title appears in front of your name as [Title name] in chat, the tab list and above your head.
- Pokémon Professor title: ops grant it, and a Professor can right-click a new player with an empty hand to open their starter selection.
Wonder Trade and GTS
- Wonder Trade for a fee, and a Global Trade Station with global, priced listings.
- Paid in CobbleDollars, with a configurable listing limit, tax, cooldown, price range and banned species.
- Updates live, so a listing disappears for everyone the moment someone buys it.
Hunt Noticeboard
- A craftable 3x2 noticeboard block with its own cork-board texture, placeable in any direction.
- Shared missions for the whole server: capture, defeat, and very rarely, catch a legendary. Once a hunt is taken it is gone for everyone.
- Rewards are items or CobbleDollars.
- The board updates live and refreshes every hour, with a countdown on the screen.
Operator tools: Pokémon mode
- The Pokémon Whistle lets operators become or control any Pokémon, walking and animating exactly as they move.
- Other players can ask to ride an operator's Pokémon form or carry it on their shoulder, and the operator accepts or denies.
Extras
- Apricorn trees and seeds, mint seeds, and dye-colored Pokédexes.
- Dimension balls and the Legendary Horn.
- Tooltips on the balls.
Commands
/trainer, /wondertrade, /gts, /market, /hunt (or /noticeboard), /pokemode and /ridepoke. Most players only need the first four. Operators get extra subcommands for badges, roles, titles, hunts and the economy.
Configuration
Config files are created on first run in the config folder: gaatsumon_trainer.json, gaatsumon_market.json and gaatsumon_hunts.json. They control star requirements, titles, prices, tax, hunt rewards and timers.
Any feedback would be greatly appreciated
