Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Draw Bridge". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: 2.5D Side-Scrolling view. Use an **Orthographic Camera** to simulate the flat, cartoonish 2D aesthetic seen in the reference image while using 3D models. * **Color Palette**: Bright and high saturation. Sky blue background (`#4FC3F7`), Red car (`#FF0000`), Grey brick textures for platforms, and Silver/Metallic for obstacles (sawblades). * **Models & Geometries**: * **Car**: A low-poly hatchback car. Wheels must be separate meshes capable of rotation. * **Terrain**: Blocky, grid-based brick platforms (Start point and End point). * **Obstacles**: Rotating circular sawblades with jagged edges. * **The Line (Bridge)**: A dynamic black tube or ribbon mesh generated by user input. It must look like a thick pencil stroke. * **Mobile Optimization**: Use simple materials (MeshLambertMaterial or MeshToonMaterial) to reduce GPU load. Limit shadow casting to the car only. ### 2. Audio Requirements * **BGM**: A lighthearted, looping "thinking/puzzle" track—playful pizzicato strings or soft marimba. * **Sound Effects (SFX)**: * **Drawing**: A scratching pencil-on-paper sound loop while the user is dragging their finger. * **Car**: A generic engine rev sound when the simulation starts. * **Collision**: A metallic "clunk" or wood breaking sound if the car hits an obstacle or falls. * **Win**: A cheerful "Ding!" or confetti pop sound when reaching the flag. ### 3. Gameplay Loop * **Phase 1: Drawing (Paused Physics)** * The car and obstacles are frozen (or idling). * The player draws a continuous line on the screen to bridge gaps or create ramps over obstacles. * The line uses raycasting to map 2D touch coordinates to 3D world space (Z-axis fixed at 0). * **Phase 2: Simulation (Active Physics)** * Once the player lifts their finger (or presses a "Play" button), the drawn line solidifies into a static physics body (MeshCollider). * The car applies torque to wheels and moves forward automatically. * **Physics Logic**: The bridge must support the car's weight. The car has gravity. * **Win Condition**: The car collides with the "Flag" trigger zone on the target platform. * **Lose Condition**: The car falls off the screen (y < -10), touches a sawblade, or gets stuck upside down for more than 3 seconds. ### 4. Mobile Controls & Interaction * **Input Method**: Touch and Drag. * `touchstart`: Begin drawing a line trace. * `touchmove`: Update the line geometry dynamically. Add points to the path. * `touchend`: Finalize the shape and trigger the physics simulation. * **Screen Orientation**: **Landscape** is preferred for bridge span visibility, but the camera zoom should adapt to keep both Start and End platforms visible on different aspect ratios. * **Visual Feedback**: * Show a "Ghost Pencil" icon following the user's finger while drawing. * The line should turn from semi-transparent black (sketching) to solid black (physics enabled) upon release. * **UI Elements**: Large, thumb-friendly "Restart" and "Next Level" buttons (min-height 50px) appearing on the Win/Loss screen. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Draw Bridge is a captivating physics-based puzzle game that challenges your creativity and engineering skills. In this brain-teasing adventure, you become the architect of rescue missions, drawing bridges, ramps, and pathways to guide stranded cars through dangerous obstacles to safety. With its intuitive drawing mechanics and progressively challenging levels, Draw Bridge offers an engaging experience for puzzle enthusiasts of all ages.

The game combines the satisfaction of creative problem-solving with the excitement of physics-based gameplay, where every line you draw matters for the car's successful journey.

Core Features

Creative Bridge Construction

Become a master architect as you design and draw custom bridges to save vehicles in distress. Each level presents unique challenges that require careful planning and resource management. Your hand-drawn structures must be both creative and functional, capable of supporting the car's weight while providing a safe passage to the destination.

Physics-Based Gameplay

Every bridge and pathway you create follows realistic physics principles. The car will react naturally to your constructions, making each solution feel authentic and rewarding. Understanding weight distribution, angles, and structural integrity becomes crucial for success.

Progressive Challenge System

Start with simple gap-crossing scenarios and advance to complex multi-obstacle courses. As you progress, new elements like moving platforms, rotating gears, and hazardous terrain add layers of complexity that will test your ingenuity and spatial reasoning skills.

Intuitive Drawing Interface

The game features user-friendly drawing mechanics that make it accessible to players of all skill levels. The responsive controls allow for precise line drawing, giving you complete control over your bridge designs.

Game Mechanics

Drawing System

Use your mouse to draw lines, curves, and shapes that form bridges, ramps, and support structures. The drawing tool responds smoothly to your input, allowing for both simple straight bridges and complex architectural solutions.

Resource Management

Many levels limit the amount of material you can use, adding a strategic element to your designs. Efficiency becomes as important as creativity when working with limited resources.

Multiple Solution Paths

Most puzzles can be solved in various ways, encouraging experimentation and creative thinking. Whether you prefer minimalist designs or elaborate constructions, the game rewards innovative approaches.

Operation Guide

Mouse Controls: - Hold and Drag Left Mouse Button : Draw lines and shapes to create bridges and pathways - Release Mouse Button : Complete your current line segment - Click Play Button : Test your bridge design and watch the car attempt to cross

Gameplay Tips: 1. Study the level layout before drawing 2. Consider the car's path and momentum 3. Build sturdy foundations for longer bridges 4. Use triangular supports for added stability 5. Test different approaches if your first attempt fails
