About this project
What does Fun Performance Booster add?
Fun Performance Booster (Utility Utilities)
Fun Performance Booster is an advanced, lightweight server and inventory management utility designed for Minecraft 1.21.1 using the Forge API. It introduces persistent cross-session cloud storage grids, specialized tool enhancements, and streamlined item configuration pipelines directly into your gameplay loop.
── Key Features ──
📦 Extended 216-Slot Persistent Safe Storage
Paged Interface: Access an independent, massive 216-slot inventory array split cleanly across 4 dynamically updating sub-pages (54 slots per page, matching a double chest layout).
Cross-Session Persistence: Items stored within this database persist securely across player deaths, bypassing standard world rules such as
keepInventory false.
🔄 Integrated Duplication Matrix
Instant Replications: Features a 1-Input, 1-Output optimization slot system. Placing any compatible item into the input slot instantly generates a maximum stack size copy in the output slot.
Balanced Blacklists: Certain high-value progression components—such as Rotten Flesh—are strictly blacklisted from the matrix to preserve core server progression and balancing.
⚡ The "SUPERDUPER" Dynamic Item Upgrade Suite
Transform regular equipment into high-performance tools instantly by holding an item and utilizing the unified upgrade pipeline. Upgraded items receive an exclusive red "SUPER" name prefix and 10x base durability scaling:
Mining Tools (Pickaxes, Shovels, Axes, Hoes): Grants instant-mining velocities (Efficiency 100) and maximized yield multipliers (Fortune 10).
Global Tier Harvesting: Upgraded pickaxes completely bypass block-tier restrictions. A SUPER Wooden Pickaxe can successfully mine and harvest end-game materials like Diamond Ore or Obsidian.
Combat Weaponry (Swords, Axes): Applies massive damage modifiers (Sharpness 100), optimized drop multipliers (Looting 10), Fire Aspect, and Knockback.
Iron Armor Reinforcement: Upgrading any held piece of Iron Armor instantly infuses it with maximum resilience values (Protection 20), Thorns, Mending, and Unbreaking.
🔴 Permanent Maximum Health Expansion
Flesh Purification: Upgrading Rotten Flesh purifies its food data components, completely removing standard hunger or poisoning side-effects.
Heart Container Injection: Consuming a piece of SUPER Rotten Flesh permanently expands your health pool by 1 full heart container (+2.0 Max Health) and restores your health instantly.
