Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Hill Racing". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 2.5D Aesthetic using an **Orthographic Camera**. The game should use 3D models but render them with a "Toon Shader" or flat shading to mimic the vibrant 2D vector art style of the reference image. * **Terrain Generation**: Implement an infinite procedural terrain generator using Perlin Noise or Sine waves to create smooth, rolling hills. The terrain geometry should consist of a "cap" (green grass texture) and a "body" (brown dirt texture). * **Vehicles**: Create a low-poly vehicle (e.g., a Red Jeep or Tractor) composed of a chassis and independent wheel meshes. The wheels must have visible suspension movement. * **Background**: Use a parallax scrolling effect with multiple layers of 2D planes (billboards) representing a yellow/green forest. The background layers should move slower than the foreground to create depth. * **Performance**: Use `InstancedMesh` for repetitive environment objects (like background trees or rocks) and merge geometries where possible to minimize draw calls for mobile performance. ### 2. Audio Requirements * **BGM**: An upbeat, looping "Bluegrass" or "Country Rock" track with banjo and drums to match the adventurous hill-climbing theme. * **Sound Effects (SFX)**: * **Engine**: A continuous looping engine sound that modulates pitch based on the car's speed/RPM. * **Suspension**: A "squeak" or "thud" sound when the car lands hard. * **Collectibles**: A high-pitched "Ding" for collecting Stars and a liquid "Gulp" sound for Fuel bottles. * **Game Over**: A comedic "crash" sound or a horn honk when the player flips the car. ### 3. Gameplay Loop * **Physics Engine**: Integrate **Cannon.js** or **Matter.js** (2D mode) to handle vehicle physics. The car must be a "Raycast Vehicle" or a constraint-based compound body to simulate bouncy suspension and center-of-gravity shifts. * **Objective**: Drive as far as possible without flipping the car over (head hitting the ground) or running out of fuel. * **Mechanics**: * **Air Control**: When in the air, accelerating tilts the nose up (backflip rotation), and braking tilts the nose down (frontflip rotation). * **Fuel System**: A fuel bar constantly depletes. The player must collect Red Jerry Cans placed on the terrain to refill the bar. * **Scoring**: Score is based on distance traveled + Stars collected. * **Difficulty**: The terrain should become steeper and more jagged as distance increases. ### 4. Mobile Controls & Interaction * **Screen Orientation**: Landscape Mode (Force landscape if possible). * **Touch Controls**: * **Two-Pedal System**: Two large, semi-transparent virtual buttons at the bottom corners of the screen. * **Left Button**: Brake / Reverse / Rotate Counter-Clockwise (Air). * **Right Button**: Gas / Accelerate / Rotate Clockwise (Air). * **Responsiveness**: Controls must use `touchstart` and `touchend` events for zero latency. * **UI Layout**: * **Top Left**: Distance/Score text (large, bold font). * **Top Center**: Fuel Gauge (Horizontal bar, turns red when low). * **Pause Button**: Top Right (minimum 44x44px touch area). * **Feedback**: Add simple camera shake on heavy impacts and subtle screen flash when collecting fuel. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Hill Racing is an adrenaline-pumping hill climb racing adventure that challenges players to master the art of uphill driving. This captivating driving game combines physics-based gameplay with strategic fuel management, creating an engaging experience that keeps you coming back for more. Navigate through treacherous terrain using a variety of vehicles including monster trucks and racing cars, each offering unique handling characteristics for different challenges.

Core Features

Diverse Vehicle Selection

Choose from an impressive lineup of vehicles, each designed for specific terrain challenges. From agile racing cars perfect for speed runs to powerful monster trucks built for rough terrain, every vehicle offers a unique driving experience with distinct acceleration, handling, and fuel efficiency properties.

Dynamic Hill Climbing Challenges

Experience realistic physics as you tackle steep inclines, rocky paths, and unpredictable terrain. The game's advanced physics engine ensures that every jump, landing, and climb feels authentic, requiring skill and strategy to master each course.

Strategic Fuel Management

Fuel collection adds a crucial strategic element to the gameplay. Plan your routes carefully to collect fuel bottles while maintaining momentum. Running out of fuel means game over, making resource management as important as driving skill.

Star Collection System

Collect stars scattered throughout each level to boost your score and unlock achievements. These collectibles are strategically placed to reward skilled driving and exploration, encouraging players to take risks for higher rewards.

Gameplay Mechanics

The core gameplay revolves around mastering the balance between speed, fuel consumption, and terrain navigation. Players must accelerate and decelerate strategically to maintain vehicle stability while climbing hills, avoiding flips, and ensuring they don't run out of fuel before reaching checkpoints.

Operation Guide

Master the simple yet effective control scheme:

  • A key or Left Arrow : Decelerate your vehicle for better control on steep descents
  • D key or Right Arrow : Accelerate to gain momentum for challenging climbs
  • Left Mouse Button : Interact with menus and in-game interface elements

The key to success lies in finding the perfect balance between acceleration and deceleration. Too much speed can cause dangerous flips, while too little momentum will leave you stuck on steep inclines.
