POSMP - All in One SMP Plugin v1.4.1

Critical Fixes Applied:​

1. Default Storage Changed to FILE - EnderChest and config now default to YAML instead of MySQL, eliminating connection errors
2. features.yml Save Conflict Fixed - Removed duplicate save attempts causing "file already exists" errors
3. SellGUI Complete Config - Added missing gui.main.title, categories, and all GUI sections to default config
4. Material Name Compatibility - Added automatic fallback handling for 1.21.x material naming variations (WOODEN_/WOOD_, GOLDEN_/GOLD_, PORK/PORKCHOP)

Result:​

• No more MySQL connection errors on startup
• SellGUI loads all 7 categories properly
• GUI opens correctly (no grey screen)
• All material names work across Minecraft versions

UPGRADE INSTRUCTIONS
========================================

From v1.3.8 or v1.3.9:

1. Stop your server
2. Backup plugins/PoSMP/ folder
3. Replace old JAR with PoSMP-1.4.0.jar
4. Start server
5. No config changes needed

For Skript Support (Optional):

1. Install Skript 2.9.5+ from SkriptLang releases
2. Install PoSMP 1.4.0
3. Restart server
4. Create scripts in plugins/Skript/scripts/
5. Check console for "PoSMP Skript addon loaded successfully"

2. Restart server
3. Make new sales to populate new history format
4. History will now show full item details



========================================
WHATS NEXT
========================================

Planned for v1.5.0:

• Shop GUI
• More Skript syntax elements (home, TPA, bounty, marriage)
• Team levels and XP system
• Team wars and competitions
• More crystal economy options
• Async database operations
• Enhanced GUI customization
• Better conflict detection
• Performance optimizations

No more command conflicts! PoSMP now automatically detects if you have Essentials or similar plugins installed and adjusts command registration accordingly.

How It Works

• With Essentials/CMI Installed: Uses prefixed commands (/pgamemode, /pfly, /ptp, /pheal)
• Without Essentials: Gets clean, intuitive commands (/gamemode, /fly, /tp, /heal)
• Zero Configuration: Works automatically - no setup required!

Commands Now Affected
Core gameplay commands (now prefix-free when safe):

• /gamemode (with aliases /gm, /gma, /gmc, /gms, /gmsp)
• /fly, /god, /vanish, /heal, /feed, /back
• /tp, /spawn, /time, /weather

Technical Improvements

• CRITICAL FIX: Resolved command override conflicts with Essentials
• Dynamic Registration: Commands registered at runtime after conflict detection
• Clean Shutdown: Fixed plugin shutdown errors
• Backward Compatible: All existing functionality preserved

User Experience

• Essentials Users: Everything works as before with prefixed commands
• Non-Essentials Users: Enjoy clean, intuitive commands without awkward prefixes
• Server Owners: Zero configuration - just works automatically!

Bug Fixes Applied​

1. Shutdown Error Fixed

• No more IllegalPluginAccessException during server shutdown
• Data saving now works properly (sync during shutdown, async during normal operation)

1. Essentials Commands Fixed

• /pspawn, /psetspawn, /pheal, /pfly etc. now work correctly
• 'p' prefix preserved to prevent Essentials conflicts
• Config properly controls command availability

PoSMP v1.3.5 Update​

Released: October 5, 2025

What's New​

Auction House Improvements​

No more inconvenient purchases! Right-clicking an item now shows a confirmation screen before buying. You'll see exactly what you're purchasing, the price, and buttons to confirm or cancel. Much safer and clearer than the old double-click system.

TPA Request Fixes​

Fixed the accept/decline buttons in TPA requests - they actually work now when you click them!

Bounty System Updates​

• New command: Players can now cancel bounties with /bounty cancel <player> Be sure to give players the following permission: posmp.bounty.cancel.self
• Less spam: Bounty reminders now appear every 10 minutes instead of every 30 seconds
• Players who cancel bounties lose 50% of their fee and refunds the remainder to them (configurable for server owners) [bounty.yml]
• Fixed /Bounty map - typing player name - so you can bind map to the player you want to hunt!

Why This Matters​

• Safer item purchases with visual confirmation
• Working TPA buttons (no more frustration!)
• Quieter bounty notifications that don't spam chat

Scoreboard.yml now allows you to switch server location (for ping). That's about it really!

PoSMP v1.3.4 - Patch Notes​

Release Date: October 2, 2025

Overview​

Version 1.3.4 brings critical bug fixes to the SellGUI system, comprehensive MySQL database support for 12+ features, and improved transaction history interface.

Database Support (MySQL + File Storage)​

12 Features with MySQL Persistence​

Full MySQL database support for data persistence across server restarts. All features support both MySQL and file-based storage (YAML/SQLite) with automatic fallback.

Features with Database Support: Home System, Team System, Stats System, Crystal Currency, AFK System, Settings System, Bounty System, Auction System, Build/Claims, Crates System, SellGUI System, Marriage System

Configuration Locations​

Centralized Configuration (5 Features) File: plugins/PoSMP/config.yml

• Home, Team, Stats, Crystal, and AFK features use shared centralized storage in the player-data-storage section

Individual Feature Configurations (7 Features) Each feature has its own storage section in their respective config files:

• Settings: features/settings.yml
• Bounty: features/bounty.yml
• Auction: features/auction.yml
• Build: features/build.yml
• Crates: features/crates.yml
• SellGUI: features/sellgui.yml
• Marriage: features/marriage.yml

Example storage configuration:

storage:
type: yaml
# Options: yaml, mysql

mysql:
host:
localhost
port:
3306
database:
posmp
username:
root
password:yourpassword

table-prefix: posmp_

Database Features​

• Automatic table creation
• Connection pooling with HikariCP
• Auto-reconnect and async operations
• Automatic fallback to file storage if MySQL unavailable
• Transaction support for data integrity

Critical Bug Fixes​

SellGUI Payment System - CRITICAL FIX​

Issue: Players were being paid 64x more than intended for all items sold.

• Example: 64 Birch Logs worth $128 total was paying $8,192

Fix: Removed duplicate multiplication in payment calculation methods.

Transaction History Values - CRITICAL FIX​

Issue: Transaction history showed wildly incorrect values.

• Example: Sold 64 Carrots for $96, but history showed $6,758.40

Root Cause: When saving to database, history multiplied value by item amount again when value already included the full stack.

Fix: Removed duplicate multiplication when saving to history database. Note: Existing history entries will still show incorrect values - only new transactions after this update will be accurate.

Feature Improvements​

Item Value Display - Permission Removal​

Change: Removed permission requirement for viewing item values.

• All players can now see item values in tooltips and actionbar
• No posmp.itemvalue.actionbar permission required

Transaction History - Improved Clarity​

Changes:

• Removed confusing "Avg/Item" from history displays
• Changed "Total Value" to "Total Payment" for clarity
• Individual items show "Worth: $X each" and "Sold for: $XXX"
• Fixed SQL query to properly sum all items in a transaction

Tax System - Disabled by Default​

Tax rate set to 0.0 by default in configuration. Can be re-enabled by changing tax-rate in sellgui.yml.

Missing Message Configuration​

Added missing tax-message configuration to messages section.

Technical Changes​

• Fixed payment calculation.
• Fixed transaction history value storage
• Removed permission check from actionbar display for item values
• Updated transaction detail tooltip labels for clarity
• Added intelligent GUI item detection to prevent value tooltips on GUI buttons
• Added storage sections to all feature configs with MySQL examples
• Enhanced config.yml with centralized player-data-storage section

Upgrade Instructions​

Standard Upgrade (File Storage)​

1. Stop your server
2. Backup your current plugin
3. Remove old PoSMP Folder (your previous data will be deleted)
4. Replace PoSMP-1.3.3.jar with PoSMP-1.3.4.jar
5. Restart server - new config sections will auto-generate

MySQL Migration (Optional)​

1. Create MySQL database and user
2. Update configuration files (change type: yaml to type: mysql)
3. Restart server - tables will auto-create and data will migrate
4. Verify in console for successful initialization

Impact Summary​

Payment Calculation Bug	Critical	Fixed
Transaction History Values	Critical	Fixed
MySQL Database Support (12 features)	Major Feature	Added
Item Value Permissions	Medium	Fixed
Transaction Display Clarity	Medium	Fixed
