Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Doodle Road**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** "Paper & Pencil" aesthetic (2.5D view). Use an **Orthographic Camera** to simulate a flat 2D drawing surface. * **Background:** A cream/off-white infinite plane with a subtle, light-blue grid pattern (resembling graph paper). * **Player Character (Car):** A stylized, low-poly red SUV/Jeep composed of simple geometries (BoxGeometry for body, CylinderGeometry for wheels). Apply a "Toon Shader" or simple flat materials with black outlines to mimic a doodle. * **The Line (Brush):** The path drawn by the player must look like a thick black marker or pencil stroke. Use a custom mesh generation or `THREE.Line` with reasonable thickness. Implement curve smoothing (e.g., Catmull-Rom spline) to prevent jagged edges from finger input. * **Goal:** A checkered flag or a square texture with a black and white checkerboard pattern. * **Optimization:** Use texture atlasing where possible. Limit draw calls. Ensure geometry is simple (low vertex count) since the physics engine will need to mesh with the visual lines. ### 2. Audio Requirements * **BGM:** A light, playful, acoustic guitar or whistling track (looping) that evokes a "creative classroom" or "DIY" vibe. * **SFX - Drawing:** A scratching pencil-on-paper sound that loops while the user is actively dragging their finger/cursor. * **SFX - Car:** A toy car engine hum (pitch increases with velocity). * **SFX - UI:** A "pop" sound for buttons and a "crumple" paper sound for the Restart action. * **SFX - Win/Lose:** A short cheerful trumpet/chime for reaching the flag, and a comedic "clunk" or slide whistle for falling off the map. ### 3. Gameplay Loop * **Phase 1: Planning (The Drawing Phase):** * The game starts paused (Physics frozen). * The car is spawned at a fixed Start Point. The Goal is at a fixed End Point. * Obstacles (Walls, Gaps) are placed according to the level data. * The player draws a continuous line on the screen. The line has a maximum length limit (ink meter). * **Phase 2: Action (The Driving Phase):** * Player presses a "GO" button. * The drawn line creates a static physics body (collidable mesh). * Gravity is enabled. The car accelerates (simple wheel torque) onto the drawn path. * **Victory Condition:** The car collides with the Checkered Flag zone. * **Failure Condition:** The car falls below a certain Y-threshold (off the paper) or gets stuck (velocity approx. 0) for more than 3 seconds after the "GO" phase starts. * **Mechanics:** * Implement basic 2D physics (using Cannon.js or similar library compatible with Three.js). * Level progression: Start with flat gaps, then walls to bridge over, then "Engine Off" levels (car relies purely on momentum/gravity slopes). ### 4. Mobile Controls & Interaction * **Touch Input (Drawing):** * Raycasting from screen space to the Z=0 plane. * **Drag:** Draws the line. Must support multi-touch rejection (only one finger draws). * **Smoothing:** Implement a minimum distance threshold between points to filter out shaky input from fingers. * **UI Overlay (HTML/CSS over Canvas):** * **Go Button:** Large green "Play" icon (bottom right, thumb accessible). * **Restart/Trash Button:** Large red "Reset" icon (bottom left) to clear the current line. * **Ink Meter:** A visual bar at the top showing how much line length is remaining. * **Orientation:** Force Landscape mode (or scale camera zoom dynamically if Portrait, but Landscape is preferred for horizontal travel). * **Feedback:** Slight vibration (Haptic Feedback API) when drawing the line. Visual particle dust when the car lands on the line. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Doodle Road is an imaginative 2D casual puzzle game that brilliantly combines creative drawing with strategic problem-solving. This captivating browser game challenges you to draw paths that successfully guide a car from the starting point to the checkered finish line. What starts as a simple concept quickly evolves into a mind-bending physics puzzle that tests both your creativity and logical thinking skills.

The game features a clean, minimalist art style with a distinctive doodle aesthetic that makes every level feel like sketching in a notebook. Each challenge presents unique obstacles and terrain that require different drawing strategies, ensuring no two levels feel the same.

Core Features

Creative Drawing Mechanics

The heart of Doodle Road lies in its intuitive drawing system. Simply use your mouse to draw lines that become physical paths for your car to drive on. The physics engine realistically simulates how your drawn paths interact with the car's movement, making every line you draw matter.

Progressive Difficulty System

Starting with simple straight-line challenges, the game gradually introduces complex obstacles: - Walls and barriers that block direct paths - Gaps and chasms requiring creative bridge solutions - L-shaped obstacles demanding strategic route planning - Engine-off levels where momentum and gravity become crucial - Spring mechanisms that launch your car toward targets

Physics-Based Challenges

By level 5, the game introduces its most innovative feature: levels where your car's engine shuts off. These physics-heavy challenges require you to understand momentum, gravity, and velocity curves to create paths that naturally propel your car to victory.

Multiple Level Variety

With numerous levels to explore, each stage introduces fresh mechanics and obstacles that keep the gameplay engaging. From underground tunnels to aerial trampolines, every level presents a unique puzzle to solve.

Gameplay Mechanics

Drawing Strategy

Success in Doodle Road requires understanding that drawing isn't just about connecting two points. Your lines must be: - Structurally sound - capable of supporting the car's weight - Strategically angled - providing proper momentum and direction - Properly positioned - starting from behind the car to create functional paths

Physics Mastery

The game's physics engine adds realistic weight and momentum to every interaction. Players must consider: - Gravity effects on steep inclines and declines - Momentum conservation through curves and hills - Velocity management for successful landings and jumps

How to Play

Basic Controls

  • Left Mouse Button : Draw your path lines
  • R Key or Restart Button : Reset the current level
  • Space Bar or Start Button : Begin the level

Gameplay Steps

  1. Analyze the level : Study the starting position, target, and obstacles
  2. Plan your route : Consider the most efficient path around barriers
  3. Draw strategically : Create paths that account for physics and momentum
  4. Test and adjust : Use the restart function to refine your approach
  5. Master physics levels : Learn to use gravity and momentum when the engine is off

Pro Tips for Success

  • Start drawing lines from behind your car for proper connection
  • Consider going under obstacles instead of over them
  • Use hills and curves to build momentum in engine-off levels
  • Experiment with different line angles to optimize car movement
  • Take advantage of spring mechanisms for extra propulsion
