Please use Three.js to generate a **mobile-first game** with the theme "**Truck Loader: Industrial Magnet**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Side-Scroller. Use a semi-realistic but stylized "industrial cartoon" aesthetic. * **The Loader:** A yellow and black industrial vehicle (resembling a forklift/rover hybrid) with big rugged wheels. It features an articulated mechanical arm. The arm's tip is a C-shaped magnet that emits a glowing cyan electric particle effect when active. * **The Cargo:** Various wooden crates with metal reinforced corners and "Fragile" stamps. Some are rectangular, some square. * **The Environment:** An industrial warehouse setting. Background should be a dark, textured metal wall (rusty steel plates) with oil stains and rivets to add depth. Foreground platforms are concrete or steel girders. * **The Truck:** A large green transport truck parked on one side of the screen with an open cargo bay area marked with yellow hazard tape, indicating the target drop zone. * **Mobile Optimization:** Use simple geometries (BoxGeometry, CylinderGeometry) with baked textures where possible to keep draw calls low. Use unlit or basic materials for background elements to save GPU power. Shadows should be baked or limited to the main character. ### 2. Audio Requirements * **BGM:** A funky, rhythmic industrial track. Think bass-heavy beats mixed with metallic percussion (clanking sounds) but kept lighthearted and catchy to suit puzzle solving. * **SFX:** * **Engine:** A low, rumbling diesel idle sound that increases in pitch when moving. * **Magnet:** A distinct "humming/zapping" electric sound when the magnet is activated, and a satisfying metallic "CLANK" when it successfully latches onto a box. * **Hydraulics:** Hissing sounds when the mechanical arm moves. * **Collision:** Heavy wood thuds when boxes hit the floor; metal screeches if the loader scrapes walls. * **Success:** A cheerful air-brake hiss and a truck horn blast when the level is completed. ### 3. Gameplay Loop * **Objective:** The player must pilot the loader to pick up scattered crates and stack them into the designated green area inside the truck's cargo bay. * **Physics-Based Puzzle:** * The core mechanic is the **Magnetic Arm**. It has physics joints allowing it to swing. The magnet can attract metal-tipped boxes but not other environment objects. * Boxes have weight and friction. Stacking them poorly will cause them to topple. * The vehicle can jump slightly to clear small obstacles or adjust positioning. * **Win Condition:** All target boxes are placed inside the truck's marked zone and stay stable for 3 seconds. The truck then drives away. * **Lose Condition:** The vehicle overturns and cannot right itself, or a critical box falls into an unreachable pit (out of bounds). ### 4. Mobile Controls & Interaction * **Orientation:** Landscape Mode (best for side-scrolling precision). * **Touch Controls (Split Screen):** * **Left Half of Screen (Movement):** A virtual D-Pad or two large arrows (Left/Right) for driving the vehicle. A dedicated "Jump" button positioned slightly above the drive controls. * **Right Half of Screen (Arm Control):** * **Joystick/Drag:** A virtual joystick to aim the mechanical arm (Inverse Kinematics). The arm should follow the angle of the thumb relative to the vehicle. * **Magnet Toggle:** A large, distinct button (icon: Magnet) to toggle the magnetic field On/Off. It should glow when active. * **Haptic Feedback:** Trigger a short vibration when the magnet successfully grabs a crate, and a heavier vibration if the vehicle crashes hard. * **Camera:** The camera should smoothly follow the vehicle on the X and Y axis but keep the truck (goal) in view as much as possible, perhaps zooming out slightly when the player is far from the truck. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Truck Loader is a beloved physics puzzle game that challenges players to efficiently load cargo onto trucks using a forklift. This engaging game combines elements of puzzle-solving, physics simulation, and vehicle operation to create a uniquely satisfying gaming experience. The game's intuitive mechanics and progressively challenging levels make it perfect for both casual gamers and puzzle enthusiasts.

Core Features

Truck Loader offers an exceptional puzzle gaming experience with several standout features:

  • Free to Play : Completely free online game with no downloads required
  • Physics-Based Gameplay : Realistic physics engine that affects box movement and forklift operation
  • Progressive Difficulty : Levels start simple but become increasingly complex and challenging
  • Cross-Platform Compatible : Play seamlessly on desktop computers and mobile devices
  • Intuitive Controls : Easy-to-learn control scheme suitable for all skill levels
  • Multiple Game Modes : Various level types requiring different strategies and approaches

Engaging Puzzle Mechanics

The game's core appeal lies in its clever puzzle design. Each level presents a unique challenge where you must figure out the optimal sequence of moves to collect all cargo boxes and load them onto the designated truck. Early levels serve as tutorials, teaching basic forklift operation and box manipulation. As you progress, levels introduce obstacles, moving platforms, switches, and complex geometric arrangements that require strategic thinking.

Realistic Physics Simulation

Truck Loader's physics engine adds depth and realism to the puzzle-solving experience. Boxes respond naturally to your forklift's movements, requiring careful consideration of momentum, balance, and positioning. This physics-based approach means that brute force rarely works – success requires finesse and understanding of how objects interact in the game world.

Game Mechanics

The gameplay revolves around three core activities:

Box Collection : Navigate your forklift around each level to locate and collect scattered cargo boxes. Some boxes are easily accessible, while others require solving mini-puzzles or performing special maneuvers to reach.

Strategic Loading : Once collected, boxes must be carefully loaded onto the truck. Proper stacking and arrangement become crucial in later levels where space is limited or specific loading patterns are required.

Puzzle Solving : Many levels feature switches, platforms, barriers, and other interactive elements that must be manipulated in the correct sequence to create a path to the truck or reveal hidden boxes.

Operation Guide

Truck Loader features straightforward controls that anyone can master:

  • A/D Keys : Move your forklift left and right across the level
  • W Key : Make your forklift jump to reach higher platforms or overcome obstacles
  • Mouse : Point and click to pick up cargo boxes with your forklift's hydraulic arm
  • Strategic Movement : Combine movement and jumping to navigate complex level layouts

The control scheme is designed for precision, allowing you to make subtle adjustments when positioning boxes or navigating tight spaces. Mastering the timing of jumps and the reach of your forklift arm is key to success in more challenging levels.

Why Play Truck Loader

Truck Loader stands out in the puzzle game genre for several compelling reasons:

Mental Challenge : Each level presents a unique logical puzzle that exercises problem-solving skills and spatial reasoning. The game encourages players to think ahead and plan their moves carefully.

Satisfying Progression : The gradual increase in difficulty ensures that players are constantly challenged without becoming frustrated. Successfully completing a particularly tricky level provides a genuine sense of accomplishment.

Relaxing Yet Engaging : Despite its challenging nature, Truck Loader maintains a casual, stress-free atmosphere. There are no time limits or penalties for mistakes, allowing players to experiment and learn at their own pace.

Educational Value : The game subtly teaches principles of physics, spatial reasoning, and logical sequencing, making it both entertaining and intellectually stimulating.

Accessibility : With no download requirements and cross-platform compatibility, Truck Loader can be enjoyed anywhere with an internet connection. The simple control scheme makes it accessible to players of all ages and gaming experience levels.
