Hello, this is a vehicle add-on that incorporates a nearly finished version of the XK Engine, which was under development as the successor to the fLUX Engine. While the engine is almost fully functional, it is not yet complete, and development has been discontinued. We are releasing it in its current state based on its current functionality. There are no plans for future updates.

The instructions below are from the fLUX Engine era. While they are still largely compatible, some features have changed, and the Discord invite link no longer works.

What is Land Rover Discovery4?

The Discovery 4 represents the final chapter of Land Rover’s classic SUV design. Its boxy shape and distinctive rear styling aren’t just aesthetic—they reflect purpose and presence. With a spacious interior and 7-seat layout, it’s perfect for family journeys and versatile enough for both urban roads and rugged terrain. Blending British elegance with practicality, the Discovery 4 was discontinued in 2016, but it remains a timeless icon for those who value authenticity in their SUVs. Now, with unmatched historical accuracy and immersive design, we present the ultimate SUV—ready to roam Minecraft’s untamed wilderness like no other vehicle before it!

How does it work?

 

What is fLux Engine?

fLux Engine is a fundamental add-on that transforms a basic vehicle add-on—once limited to boarding and movement—into a fully immersive driving experience with realistic features.

🚘 Vehicle System Overview

🚙 Vehicle Boarding & Ignition System

• 🏁 Boarding a Vehicle
  
  • Interact with the vehicle and press the board button to enter.
  • You must hold the car key item after boarding.
• 🔑 Ignition System
  
  • Vehicles can be started and turned off.
  • 🚷 You cannot exit the vehicle while the engine is running.
  • ✅ Turning off the engine allows you to exit the vehicle.
• 🎗️ Seatbelt System
  
  • After boarding, interacting with the car key opens a UI with ignition and seatbelt options.
  • ⚠️ Seatbelt usage is optional
  • ❌ You can start the engine without wearing it.
  • ✔️ If worn, it reduces external damage from attacks.

⚙️ Automatic Transmission Controls

• 🅿️ P (Park) The vehicle moves at a limited speed.
• 🔁 R (Reverse) The vehicle moves backward.
• ⚖️ N (Neutral) Allows pushing the vehicle.
• 🚗 D (Drive) Enables normal-speed driving; speed adjustments available in the main UI.

⏩ Speed Control & Fuel Management System

• 🚦 Vehicles can adjust speed in 5 stages, from 30 to 220.
• 🔄 Gradual acceleration—RPM increases slowly before reaching the set speed.
• ⛽ The higher the speed, the more fuel is consumed.
• 💤 When idle, fuel consumption is minimal, but the engine still uses a small amount.
• ⚡ High-speed driving depletes fuel quickly, so efficient speed control is essential.

🛢️ Engine Oil System

• ⚙️ Vehicles have an engine oil condition, requiring regular maintenance.
• 🚨 If engine oil level reaches 0%, fuel consumption increases drastically.
• 🏪 Engine oil must be refilled at a charge item on gas station.
• ❗ Poor engine oil condition reduces vehicle performance and fuel efficiency.
• 🔧 Routine engine oil maintenance is necessary for safe driving.

💡 Vehicle Functions & UI

• 💡 Lighting Features
  
  • Headlights, high beams, fog lights, reverse lights
  • 🚦 Left/right turn signals & hazard lights
• 🪟 Window Control for Each Seat
• 👥 Toggle Passenger Boarding On/Off
• 🎨 Enable/Disable Vehicle Customization Mode
• 📢 Honk the Horn
• 🔧 Exclusive Features for Certain Vehicles

🔑 Vehicle Key System

• 🚘 When spawning a vehicle, a unique key for that specific vehicle is automatically provided.
• 🔐 Keys cannot be used on other vehicles, even of the same model.
• 🗝️ Backup Key Available—Each vehicle receives two keys (one main, one spare) in case of loss.
• 🚗 Keys must be held to interact with the vehicle for boarding.

🔧 Vehicle Repair System

• If a vehicle's HP decreases, you can restore its health by using Iron Ingots, Gold Ingots, Emeralds, Diamonds, or Netherite Ingots on the vehicle.

💡 Vehicle Spawning & Crafting

• 🛠️ Creative Mode—Vehicles can be instantly spawned using vehicle spawn eggs.
• 🏗️ Survival Mode—Vehicles must be crafted using unique recipes

📦 Trunk System

• 🚪 Selecting the open trunk option reveals the vehicle's rear trunk compartment.
• 📦 Interacting with the trunk displays a dedicated inventory UI.
• 🎒 Items can be stored inside the trunk for later use.

🎵 Vehicle Music System

• 🎶 All vehicles can play Minecraft's default disc music.
• 📀 Two types of music playback
  
  • 🎼 Built-in Music Vehicles—Some vehicles have music stored internally, allowing immediate playback.
  • 💿 Disc Music Vehicles—Requires collecting a music disc and inserting it while the engine is running, similar to a CD player.

🎨 Vehicle Customization Mode

• 🎨 Paint spray items No.1 to No.12 can be obtained at gas stations.
• 🌈 Activating customization mode displays rainbow-colored particles near the vehicle's front.
• 🖌️ Interacting with the vehicle while holding a paint spray item changes its color.
• 🚗 Each vehicle has different preset color options, allowing unique customization.

⚠️ Collision & Damage System

• 🚗💥 Vehicles deal speed-based damage when colliding with monster entities.
• ⚡ The faster the speed, the greater the impact damage.
• ⏬ Upon collision, vehicle speed temporarily decreases, while the monster takes severe damage.

🏎️ Exclusive Features for Convertibles & Sports Cars

🌞 Convertible Roof System

• 🏎️ Convertible vehicles allow opening and closing their roof.
• 🎛️ The main UI provides roof control options.

⚡ DashBoost System (Exclusive to Sports Cars)

• ⛽ Consumes additional fuel when activated.
• ⏳ Has a cooldown period, requiring strategic use.
• 🚀 Only activates in the main UI when the vehicle reaches its maximum speed.

🏪 Gas Station System

⛽ Gas Station Spawn & Management

• 🎯 Gas stations can be spawned using a dedicated spawn egg or crafted via Survival Mode recipes.
• 🏆 The player who spawns the gas station becomes its owner.
• 🔑 Owners receive two gas station management keys (one main, one spare).

📋 Gas Station Menu

1. 🛢️ Displays current available fuel amount.
2. 🔄 Fuel token generation – Allows other players to refuel using generated tokens.
3. 🏎️ Fuel, engine oil, and paint distribution.
   
   • 🔧 Owners can distribute fuel and engine oil for vehicle maintenance.
   • 🎨 Paint sprays are available for vehicle customization mode.

🔑 Token-Based Refueling System

• 🏷️ Token Generation
  
  • Gas station owners generate tokens for vehicle refueling.
  • Tokens are used when players request refueling.
• ⛽ Refueling Process
  
  1. The gas station owner provides a fuel token.
  2. The player holds the token and interacts with the gas station.
  3. 📡 The gas station automatically detects nearby vehicles and lists them.
  4. 🚗 The player selects their vehicle from the list.
  5. ⏳ After 5–10 seconds, the vehicle is refueled.

🔋 Gas Station Fuel Refill System

• 🏗️ Owners can replenish the gas station’s fuel using coal items.
• 🔄 Interacting with the gas station while holding coal automatically refills the fuel supply.
• 💎 1 coal adds 1,000 liters of fuel instantly.
• ⚙️ Maintaining a sufficient coal stock ensures stable fuel availability.

⚠️ Gas Station Safety Guidelines

• 🔥 Never bring fire or explosives near the gas station.
• 🚨 Hazardous risks
  
  • 💥 Direct fire, Creeper explosions, or lightning strikes can cause an explosion.
  • ⛽ A gas station with stored fuel will detonate if exposed to such dangers.
• 🛠️ Proper management is required to ensure safe gas station operations.
  
  • 🏗️ Just like real-world gas stations, players should build a roof structure over the gas station entity for added protection.
  • 🌧️ A roof can shield the gas station from environmental hazards like rain or lightning.
  • 🚗 Having a covered gas station makes it look more realistic and secure.
• 🔍 Owners should eliminate potential fire and explosion hazards to prevent accidents.
