🌟 Why CappyShards?

Tired of clunky economy plugins that cause TPS lag, leak memory, or get exploited by inventory click hacks?

CappyShards is an advanced, production-ready server solution crafted from the ground up for modern Paper/Purpur 1.21+ Minecraft networks. It introduces a secondary premium economy (Shards), an AFK reward zone with an action bar display that cannot be overridden by other plugins, an intuitive in-game shop with instant unit & stack adjustments, functional consumable boosters, and bulletproof concurrency protection.

Best of all? No client mods or resource packs required. Everything runs seamlessly on vanilla Minecraft clients!

🚀 Features

⚡ 1. High-Performance Shard Economy

• Async Database Transactions: Backed by SQLite and HikariCP connection pooling. Zero lag or freezing on the main game thread.
• Atomic Anti-Dupe Locking: Uses thread-safe atomic flags (AtomicBoolean) preventing fast-click dupes, inventory drag exploits, and packet glitches.
• Player-to-Player Transfers: Secure /shard pay command with self-transfer prevention, balance validation, and transaction concurrency guards.

⏳ 2. AFK Shard Rewards & Dominant Action Bar

• Ready Out-of-the-Box: Pre-configured for world ShardAFK.
• TPS-Immune Time Tracking: Calculated using millisecond epoch timestamps (System.currentTimeMillis()) so server lag spikes won't drift or delay player countdowns.
• Priority Action Bar Engine: Pulses every 0.5s (10 ticks) asynchronously, guaranteeing your AFK countdown remains visible even when other plugins send action bar messages.
• Congratulatory Reward Banner: Displays an eye-catching reward message for 3 seconds before smoothly returning to the countdown.
• Rank Multipliers: Reward VIPs and donors with customizable payout amounts per tier.

🛡️ 3. Built-In Network Security

• Anti-Alt Protection: Limits maximum accounts allowed per IP simultaneously (configurable in config.yml).
• Anti-VPN & Proxy Shield: Performs asynchronous pre-login HTTP checks with IP intelligence APIs (e.g. proxycheck.io) to reject bots and VPN users before they join.

🧪 4. Shard Multiplier Consumables

• Instant-Use Potions: Custom Water Bottles that immediately grant a timed Shard earnings multiplier upon right-click.
• No Drinking Delay: Consumes instantly without the 1.6-second vanilla drinking animation.
• Visual & Audio Feedback: Plays level-up chimes and sparkles upon activation.
• Fully Customizable: Configure textures, custom model data, names, lores, sounds, and particles in item.yml.

🛒 5. Smart In-Game Shop

An intuitive, player-friendly shopping experience without needing custom texture packs:

• Clean Category Browsing: Organize items into custom departments (Weapons, Consumables, Materials, etc.) with customizable icons and color gradients.
• Unit & Bulk Stack Purchasing: Players can easily switch between buying single items (1 to 64) or bulk stacks (1 to 36) with simple + and - buttons.
• Smart Stack Detection: Non-stackable equipment (swords, armor, tools) automatically disables stack mode to prevent issues.
• Instant Purchase Preview: Clear summary showing selected quantity, total cost, and current balance before confirming.
• Virtual Rewards & Commands: Supports optional console commands in shop.yml for giving Crate Keys, ranks, or custom plugin items.
• Inventory Safe: Automatically checks available inventory space before transactions to avoid dropped items.

💤 6. Offline Shard Accumulation

• Passive Offline Progress: Players can accumulate Shards even while completely logged off!
• Rank-Based Duration Caps: Configurable maximum accumulation time per rank in config.yml (e.g. 2h for Default, 6h for VIP, 12h for VIP+).
• Flexible Permission Control: Grant globally using cappy.offline.shard or per-rank with cappy.offline.shard.<rank>.
• Welcome-Back Notification: Reconnecting players receive a detailed chat notification showing their offline time and shards earned.

⚡ Shard Multiplier Boosters

Admins can distribute temporary Shard Multipliers as quest rewards, crate prizes, or store items!

# Give a 2x Multiplier for 30 minutes to yourself:
/cappy give shard_multiplier 2 30

# Give a 1.5x Multiplier for 60 minutes to a player:
/cappy give Steve shard_multiplier 1.5 60

• Instant Right-Click: Right-click anywhere to immediately activate the boost.
• Boosted Payouts: While active, all AFK rewards are multiplied (e.g. 10 Shards × 2.0 = 20 Shards).
• HUD Indicator: The action bar automatically appends the active multiplier (e.g. Receiving Shards in: 45s (x2)).
