v1.5.6.2

SmartSpawner - Version 1.5.6.2

Critical Dupe Patched

• Fixed item duplication exploit caused by race condition in VirtualInventory synchronization with storage GUI

Technical Details

The exploit involved using two game instances with swarm mode (custom mod) to create a race condition between spawner inventories. This has been completely patched by:

• Synchronizing inventory operations across all connected clients
• Adding transaction verification before committing item changes
• Implementing proper locking mechanisms for concurrent access

All users running v1.5.4.3 or lower should update immediately.

v1.5.6.1

SmartSpawner - Version 1.5.6.1

🐛 Bug Fixes

• Fixed: Possible item duplication issue with "Take All" and "Drop Page" buttons
• Found by: @Raczain (Autism Inc.)

ℹ️ Note

This dupe has not been fully confirmed but has been patched as a precautionary measure. We recommend updating to this version to prevent potential exploits.

v1.5.6

SmartSpawner - Version 1.5.6

🎯 What's New

✨ New Feature: Item Spawners

What are Item Spawners?

• New spawner type with the appearance of a specific item in the spawner block
• All the same features as regular spawner spawners (storage, stack, etc.)

📝 Configuration

New Item Spawner Settings File

• Added item_spawners_settings.yml for full control over item spawner behavior
• Customize spawn loots, experience, and other settings
• New command: /ss give item_spawner <player> <item_type> [amount]

🔧 Bug Fixes

Fixed Storage GUI Page Display Issues

• Problem: When you removed items from your spawner storage, the page counter at the top would sometimes show weird placeholders like [{current_page}/{total_pages}] instead of the actual page numbers like [1/1]
• What fixed:
  • Page numbers now always display correctly when you take items out of storage
  • When your spawner generates loot while you have the storage open, the page counter updates properly
  • The GUI title now always shows the right page you're on and total pages available

🛡️ Security & Performance Improvements

Added Anti-Spam Protection for Storage GUI

• What this means: We've added a short cooldown (half a second) between opening and closing your spawner storage
• Why this helps: Prevents issues with cheater try to spam-click or use macros in GUIs
• Your experience: You won't even notice this - it only blocks actions that happen too fast to be intentional

Optimized Storage Title Updates

• What changed: The plugin now only updates the page counter when it actually needs to (like when moving between pages)
• Benefit: Better performance, especially if you have many items in storage

🔌 Developer Features

New API Methods for Custom Spawners

Plugin developers can now create:

• Vanilla Spawners: Natural spawners that spawn mob
• Item Spawners: Special spawners with the appearance of a specific item in the spawner block

---

📋 Summary

This is a major feature update! We've introduced Item Spawners - a completely new way to use spawners for automatic item generation. Plus, we fixed annoying storage GUI display bugs, added protection against spam-clicking, and improved overall performance.

Upgrade highly recommended: New features + important bug fixes and stability improvements.
