TCrates

📦 TCrates — The Next-Generation Reward Engine

---

⚡ What is TCrates?

Most crate plugins in Minecraft were designed almost a decade ago — heavy on the main server thread, bloated with obsolete libraries, lacking player-retention mechanics, and using outdated formatting.

TCrates is a completely modern, high-performance reward and crate engine designed from the ground up for modern Paper and Purpur servers (1.21+). Built with zero-lag asynchronous architectures, production-grade connection pooling, and modern Adventure MiniMessage text, it transforms ordinary crate opening into an addictive, fair, and engaging gamified experience.

✨ Key Features & Game Mechanics

🎯 1. Fair Gacha & Pity System (Guaranteed Rewards)

No more endless bad-luck streaks for your players:

• Dynamic Pity Counters: Automatically guarantees higher-tier rewards after a configurable number of non-rare rolls.
• Transparent Drop Odds: Players can see their exact calculated percentage chance for every reward in real-time.
• Duplicate Protection: Automatically detects if a player already owns an exclusive reward and converts duplicates into shards, in-game currency, or consolation keys.

🔮 2. Shards & Alchemy Fusion

Give worthless drops real purpose:

• Unwanted or low-tier crate rewards can grant or be dismantled into Shards (COMMON, UNCOMMON, RARE, EPIC, LEGENDARY).
• Interactive Alchemy GUI (/tcrates shards) lets players fuse 10 lower-tier shards into 1 higher-tier shard, creating a satisfying long-term progression path.

🎰 3. Progressive Community Jackpots

• Every crate opened contributes a small portion to a global, server-wide Jackpot Pool.
• When a lucky player hits the jackpot, the server celebrates with broadcast announcements, particle effects, and customizable jackpot payouts.

📜 4. Interactive Crate Missions & Milestones

• Daily and weekly opening quests (e.g., "Open 5 Starter Crates" or "Fuse 3 Rare Shards").
• Players track their progress through clean progress bars in the GUI (/tcrates missions) and claim exclusive rewards.

📬 5. Offline & Overflow Mailbox

• Players will never lose crate rewards due to a full inventory or sudden disconnects.
• Undelivered items are automatically routed to their personal secure Virtual Mailbox (/tcrates mailbox), accessible anytime.

👁️ 6. Instant Left-Click Rewards Preview

• Players can Left-Click any physical crate block in the world to open an interactive, multi-page rewards preview showing item lore, rarity tiers, and exact win percentages.
• Right-Click consumes a key and launches the opening animation.

🧪 7. Monte Carlo Simulation Engine (For Admins)

• Never guess whether your crate drop rates will break your economy!
• Admins can simulate 1,000 to 100,000 rolls in milliseconds directly from the console:

  /tcrates simulate starter 10000
  

  Provides instant distribution stats, standard deviation, and payout balance verification.

⚡ 8. Modern Visuals & Zero-Lag Architecture

• MiniMessage Gradients: Crisp, high-contrast, modern gradient typography with zero unwanted vanilla italics.
• Asynchronous Database: Powered by HikariCP with non-blocking SQLite and MySQL support.
• Featherweight Footprint: Ultra-optimized JAR (< 550 KB) without unneeded shaded dependencies.

🎮 How to Setup in 60 Seconds

1. Drop into plugins/ and start your Paper 1.21+ server.
2. Place any block in the world (e.g., Ender Chest, Chest, or Beacon).
3. Look directly at the block and register it as a crate:

   /tcrates create starter
   

4. Give yourself a key to test:

   /tcrates key starter
   

5. Left-Click the crate to preview rewards, or Right-Click with the key to open!
