📦 Parcel Locker / Paczkomat

Author: dev00k
Minecraft Version: 1.21.1 (Fabric)
Supported Environments: Client & Dedicated Server (SMP, Survival, RolePlay, Modern Cities)

Bring the iconic automated parcel delivery experience straight into Minecraft! Parcel Locker / Paczkomat adds fully functional 9-block parcel locker stations with 72 opening compartments, an interactive touchscreen terminal with PIN authentication, drivable delivery vans, animated NPC couriers, and an ultra-robust logistics engine designed from the ground up for grief-free multiplayer.

✨ What's New & Changed in v0.5.1:

• 📬 Offline Recipient Support: Send packages to any player, online or offline! The recipient is instantly notified via SMS upon logging into the server (JOIN).
• ⏰ Daily Login Reminders: Sends a periodic reminder upon login (every 24,000 ticks) until the package is picked up.
• 🚚 Multi-Batching Logistics: Delivery vans and couriers unload all arriving parcels and collect all outgoing parcels in a single stop.

✨ Key Features

🏢 1. Realistic 9-Block Parcel Locker Station

• 72 Individual Compartments: Authentic metal latch clicking sound effects and smooth real-time door swinging animations.
• Protective Canopy Roof with Downlights: Built-in warm LED floodlights that illuminate the locker facade and terminal at night.
• Illuminated 3D Brand Header: Integrated lightbox header displaying custom 3D glowing text (default: PACZKOMAT, fully customizable).
• Two Visual Models:
  • Modern: Sleek, streamlined contemporary design with curved canopy trim.
  • 1:1 (Classic): Authentic real-world proportions true to iconic street parcel lockers.

🚚 2. Smart NPC Courier & Delivery Van (Multi-Batching)

• Efficient Stop Batching: Couriers never drive out for just a single package! Upon arrival at a locker, the courier:
  1. Unloads and delivers all pending incoming parcels carried in the van cargo.
  2. Loops through and collects all outgoing parcels deposited by players (up to the van capacity, default: 16 parcels).
• Player-Drivable Vans: Obtain a van ignition key (/parcellocker key), steer your own delivery van through town roads, honk the horn, and haul cargo on the bed!

⚡ 3. Virtual Async Mode for Large Servers (Zero TPS Lag)

• Running a large public server with 100+ active players and want 0% CPU impact from entity pathfinding?
• Simply switch to virtual delivery mode: "visualCouriers": false (or via in-game command /parcellocker config couriers false).
• In virtual mode, no physical entities are spawned (0 entity physics, zero TPS drops). Parcels are scheduled in background memory (MailState) and land directly into the recipient's locker after the delivery timer expires!

🛡️ 4. Full Multiplayer & Anti-Grief Protection

• 🛑 Destination Full Validation: The terminal checks available compartments at the destination locker before accepting a parcel. If full, the submission is rejected without taking items or gold.
• ⏰ Automated Expiry & Returns (parcelExpiryHours): Inactive players won't hoard lockers forever. Uncollected parcels automatically return to the sender after 48h (configurable), freeing the compartment and notifying both players.
• 🚷 Anti-Stuck & Anti-Trap Fail-Safe: If players grief or obstruct the courier's path with placed blocks, fences, or entities, an integrated fail-safe (75 ticks) teleports the courier directly to the locker or van. Deliveries are guaranteed to complete.
• 💾 Unloaded Chunks & Crash Resilience: All parcels in transit are permanently saved to the Overworld ledger (SavedData). Deliveries survive block removal, unloaded chunks, and server restarts.

📐 5. Placement Hologram & Obstacle Detector

• Holding a parcel locker in hand displays a real-time 3D glowing placement hologram and parking bay outline.
• Any colliding blocks glow in pulsating RED with 3D "REMOVE" tags and action bar alerts, pinpointing exactly what blocks need clearing before installation!

🇵🇱 Opis po polsku

Przenieś kultowe automaty paczkowe prosto do świata Minecrafta! Paczkomat dodaje do gry w pełni funkcjonalne, 9-blokowe stacje paczkomatowe z 72 skrytkami, dotykowy terminal z klawiaturą PIN, animowaną furgonetkę dostawczą, kurierów NPC oraz zaawansowany silnik logistyczny odporny na wszelkie problemy serwerów multiplayer.

Główne cechy:

• 🏢 Realistyczny Paczkomat 9-blokowy: 72 otwierane skrytki z dźwiękami rygla, daszek z nocnym oświetleniem LED, podświetlany kaseton 3D z nazwą.
• 🚚 Inteligentny Kurier (Multi-Batching): Jeden van przyjeżdża, kurier wyładowuje wszystkie paczki na danej stacji, po czym zabiera ze skrytek nadawczych wszystkie oczekujące paczki i odjeżdża.
• ⚡ Tryb Wirtualny dla Dużych Serwerów (Zero Lag): Opcja "visualCouriers": false wyłącza fizyczne pojazdy – paczki wędrują asynchronicznie, co pozwala na płynną grę nawet przy 100+ osobach online bez spadku TPS.
• 🛡️ Ochrona Multiplayer: Automatyczny zwrot przeterminowanych paczek po 48h, blokada nadania przy braku miejsca w docelowym paczkomacie, teleportacyjny fail-safe dla kuriera w przypadku zablokowania przez graczy.
• 🎨 Łatwa zmiana kolorów i nazwy: W pliku config/paczkomat.json możesz ustawić dowolną nazwę i kolory HEX (np. InPost #FFD522, Orlen #E2001A, Pocztex #003399).
