Name effects
15 animated effects (shine, wave, sparkle, heartbeat…) applied to the name according to the player’s rank, with rank gradients, a preview in the menu and placeholders for chat, tab and nameplates.
CobaltiaEffets bundles everything that makes a player recognizable and the game more pleasant day to day: animated name effects (chat, tab list, nameplate above the head), a single wardrobe for hats, backpacks, titles and companions, a gem shop fully described in YAML, a notification banner above the hotbar, and a set of quality-of-life features (chat mentions, /rtp with a daily quota, paid AFK zone, /money, /furnace, night vision…).
The plugin was built for the Cobaltia server: some features rely on the server resource pack or on its core plugin. Every integration is optional and cleanly switches off when the related plugin is missing — see Integrations.
Name effects
15 animated effects (shine, wave, sparkle, heartbeat…) applied to the name according to the player’s rank, with rank gradients, a preview in the menu and placeholders for chat, tab and nameplates.
Wardrobe
A tabbed menu to equip hats and backpacks, name effect, chat titles and companion, with pagination and a “Remove all” button.
Companions
127 cosmetic mini-mobs (including jockeys and a mini dragon) that follow the player, rendered with packets, split into four rarities with weighted random draws.
Shop
A menu-based shop described in boutique.yml: categories, items, two prices to choose from, once-per-season purchases, random boosters and commands with random picks.
Notification banner
Short-lived messages are drawn in a banner above the hotbar: fixed items on the left (job XP, AFK), queued notifications on the right, never overlapping.
Richer chat
@name mentions with a notification, @item to show the held item, leaderboard ranks and clan in front of the name, which players can hide.
RTP, AFK and jobs
/rtp with a daily quota per rank, a paid AFK zone with a daily cap, anti-abuse protections for jobs (AFK fishing, kill farming).
Server comfort
/money, /furnace, /nightvision, /give for Nexo items, tab list split by world group, tab sorting, custom MOTD and join/quit messages.
