SellChest v1.3.0
Major Update - Premium UX · 6 Languages · Tiered Audio · Full Code Audit
Premium UX Overhaul ◆ 5-Tiered Sound System ◆ 6 Languages ◆ Auto-Update Configs ◆ 7 PAPI Placeholders ◆ Full Code Audit
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
What's New in 1.3.0
This is the biggest SellChest update since release. Every message, every GUI element, every hologram has been redesigned from the ground up. The plugin now speaks 6 languages, plays tiered audio feedback, and automatically keeps all configuration files up to date - without ever touching your settings.
Premium UX Overhaul
◆ Complete Visual Redesign
Every message in the plugin has been rewritten with professional formatting, symbols, and color gradients. Gold headers with ✦ stars, dark gray ┃ separators, ◆ bullets - a consistent premium look across the entire plugin.
◆ Enchanted SellChest Items
SellChest items now have a subtle enchantment glow (hidden enchant, visual only). Your chests look as premium as they perform.
◆ Redesigned GUI
The upgrade interface now features dark-themed titles with ✦ accents, cleaner stat displays, and professional color coding for each upgrade path: gold for items, aqua for frequency, yellow for percentage.
◆ Enhanced Holograms
Holograms now show the owner's name, a summary of upgrade levels, and a clean countdown timer. Configurable text shadow, height, and view distance. Formatted sale values with comma separators: +12,345.67$
Tiered Audio and Visual System
Five tiers of sale effects based on transaction value:
Small Sale ($1+) 10 particles, EXP_ORB sound + hat chime
Medium Sale ($1,000+) 20 particles, LEVELUP (1.8x pitch) + chime
Large Sale ($10,000+) 30 particles, LEVELUP (1.4x pitch) + chime
Huge Sale ($50,000+) 30 particles + END_ROD sparkles, LEVELUP + bell
Epic Sale ($50,000+) + FIREWORK_TWINKLE for truly epic moments
GUI Sound Feedback:
Open - Chest Open · Close - Chest Close · Upgrade Success - LEVELUP + Chime · Max Level - Bass Block · No Money - Bass Block (low pitch) · Toggle - Hat Block · Pickup - Item Pickup
6 Language Support
Switch language in config.yml - no server restart needed.
English · Polish · German · Russian · Spanish · French
All language files auto-update when the plugin updates - you'll never miss new messages. Just bump lang-version and the plugin handles the rest.
Smart Auto-Update System
◆ Version-Tracked Configs
config.yml, upgrades.yml, and all 6 language files are tracked by version numbers. When you update the plugin, it automatically adds new keys from the built-in defaults - without overwriting a single setting you've customized.
◆ Configurable Processing
New config sections: processing (batch size, notification interval), hologram (height, view distance, shadow, see-through), expanded effects controls. The autosaveInterval setting now actually works (previously hardcoded).
7 PlaceholderAPI Placeholders
%sellchest_count% - Number of owned SellChests
%sellchest_earnings% - Total earnings from all chests
%sellchest_sold% - Total items sold across all chests
%sellchest_time% - Time until next sale (nearest chest)
%sellchest_nearest_items% - Items per sale of nearest chest
%sellchest_nearest_freq% - Sell frequency of nearest chest
%sellchest_nearest_perc% - Price percentage of nearest chest
Display stats on scoreboards, chat messages, or menus - fully compatible with all PAPI renderers.
Full Code Audit - 520 Lines Removed
Every Java file has been reviewed, optimized, and cleaned.
◆ Architecture Improvements
Extracted SalesProcessor class (170 lines of focused sale logic) · Centralized NBT writing method (eliminated 3x duplicate code) · Deduplicated upgrade GUI handler (140 lines into unified method) · Removed dead ConfigManager.java (200+ lines of unused code)
◆ Performance Optimizations
Removed duplicate map lookups in listeners · Cached NamespacedKeys in ChestPlaceListener · Partitioned processing with configurable batch size · Notification system with offline player timeout
◆ Number Formatting
All sale values and item counts now display with comma separators: 1,234,567 instead of 1234567. Clean, professional, readable at a glance.
Bug Fixes
V Memory Leak - Notification map grew indefinitely for offline players. Now cleaned up with 10-minute timeout.
V Data Loss - toggleRemoveUnsellableItems changes were not saved to disk (missing markDirty). Fixed.
V Hologram NPE - removeAllHolograms could crash if world was unloaded during shutdown. Safe-guarded.
V HologramTask NPE - Could crash if player was teleporting between worlds. Added null-check.
V ConfigManager NPE - Accessed MessageManager before initialization. Class was dead code, removed entirely.
V Economy NPE - Added null-check for EconomyType.getFromString("VAULT") in sales processor.
V Tab Complete - /sellchest top was missing from tab completer. Added.
V Plugin Reload - Old notification task was not cleaned up on reload. Properly shut down now.
V Version String - plugin.yml showed "unspecified". Now uses Gradle expansion: 1.3.0.
V Language Mixing - English file contained Polish words in lore keys. All 6 files verified clean.
V Log Consistency - All console messages standardized to English (were mixed Polish).
V RuntimeException Anti-Pattern - Replaced with clean boolean return flow for economy rollback.
Removed Dead Code
ConfigManager.java - 200+ lines of unused upgrade code
processSellChestSales() - unused method, replaced by partitioned processing
checkFAWE() - never-called method that always returned false
hasAnyProtectionPlugin() - unused utility method
Duplicate NBT writing - 3 identical code blocks, now one centralized method
