Effect Shop

## EffectShop 2.0.0 — Full Rewrite The plugin has been completely rewritten. One jar now supports **Minecraft 1.16.5 through 26.3** on **Spigot, Paper, Purpur, Folia** (and other Bukkit-based forks). Java 17+ required. ### Breaking changes - The command is now **`/effectshop`** (the old `/eshop` has been removed) - New `config.yml` format (v2) — your old config is automatically backed up to `config-v1-backup.yml` and ported prices must be moved over ### New - **Fully config-driven menus**: slots, sizes, materials, icons, lore, prices, durations, fill/accent panes, header and back items — everything editable, unlimited categories - **Stack modes** for buying an already-active effect: `REPLACE` (restart), `ADD` (extend duration), `MAX` (refund-free refusal while the remaining time is longer) - **Sound feedback** (open / navigate / purchase / denied), configurable resource keys - **MiniMessage** support (`<gold>`, `<bold>`, ...) alongside legacy `&` codes - Real potion items: the Invisibility icon looks like an actual potion - Close button in the main menu; staying in the menu after a purchase with live balance update - `/effectshop reload` — hot-reload the configuration (no restart) - `/effectshop test` — builds all menus headlessly (handy for setup and CI checks) - Attributes / "No Effects" lines are hidden from item tooltips on every version (data components on 1.21.5+, item flags on older servers) ### Fixes and hardening - Fixed the balance line rendering a literal `%player_level%` placeholder in the main menu - Items can no longer be moved into/out of the shop via drag or shift-click - Purchases are race-safe and verified against the live XP level ### Compatibility - Runtime capability detection instead of hardcoded versions: Adventure components, registries, data components and potion APIs all have legacy fallbacks - Folia support via the entity scheduler (`folia-supported: true`) - Verified on: Paper 1.16.5 / 1.21.11 / 26.1.2 / 26.2 / 26.3, Spigot 1.21.1, Folia 1.21.11
