MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Draw Bridge - Physics Puzzle**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a clean, bright, and semi-cartoonish 2.5D aesthetic. The background should be a simple gradient blue sky (representing a clear day). Use simple geometric shapes with clear textures. * **Key Assets:** * **The Car:** A low-poly red hatchback vehicle with visible wheels. It needs simplified physics meshes for collision. * **Terrain:** Grey brick-textured platforms representing the start and end points. * **Goal:** A red flag on a black pole situated on the destination platform. * **Obstacles:** Rotating saw blades (silver metallic texture) or gaps (death zones) between platforms. * **The Pencil:** A floating 3D pencil model that follows the user's touch/cursor to indicate the drawing position. * **Performance Optimization:** Since this is mobile-first, use low polygon counts for models. Avoid complex shadows; use baked lighting or a simple directional light. Use `LineGeometry` or instanced meshes for the drawn lines to maintain high FPS. ### 2. Audio Requirements * **BGM:** A lighthearted, upbeat, and looping "thinking music" track (e.g., marimba or light synth-pop) that encourages puzzle solving without being distracting. * **Sound Effects (SFX):** * **Drawing:** A "scribbling" sound effect that loops while the player is touching/dragging the screen. * **Engine:** A cute, small engine rev sound when the car starts moving. * **Win:** A cheerful chime or confetti sound when the car hits the flag. * **Crash/Fail:** A comedic "boing" or crash sound when the car hits an obstacle or falls off the screen. * **Physics Impact:** A soft thud when the car lands on the drawn bridge. ### 3. Gameplay Loop * **Phase 1: Planning/Drawing:** The game starts in a "frozen" physics state. The player sees the start point (car), the gap/obstacles, and the end point (flag). The player draws a line on the screen. This line instantly converts into a rigid physical body. * *Constraint:* Limit the amount of "ink" (line length) available per level to prevent spamming. * **Phase 2: Simulation:** Once the player lifts their finger (or clicks a "Go" button), gravity and physics are enabled. The car accelerates forward automatically. * **Win Condition:** The car successfully crosses the gap using the drawn bridge and touches the red flag for 2 seconds. * **Fail Condition:** The car touches an obstacle (saw blade), falls into the abyss (y-axis < -10), or gets stuck upside down. ### 4. Mobile Controls & Interaction * **Screen Orientation:** Landscape mode is preferred for bridge span visibility, but the camera should adapt FOV for Portrait if necessary. * **Touch Controls:** * **One-finger Drag:** Draws the line. The input needs to be smoothed (Catmull-Rom spline) to prevent jagged physical colliders which ruin car physics. * **Raycasting:** Ensure the touch coordinates map correctly to the 3D world plane (Z=0) regardless of screen size. * **UI Elements:** * **"Go/Play" Button:** A large, green, circular button (at least 64x64px) in the bottom right corner. * **"Reset/Retry" Button:** A refresh icon in the top right. * **Instructional Hand:** For the first level, show an animated hand texture guiding the player on how to draw a bridge. * **Feedback:** * **Haptic Feedback:** Trigger a light vibration when the car crashes or wins (if supported by the device). * **Visual Trail:** The line being drawn should have a particle trail or a "sketchy" shader effect before turning into a solid physics object. 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 puts your creativity and problem-solving skills to the test. In this engaging brain-teaser, you become the architect of safety, designing custom bridges and pathways to rescue stranded cars from dangerous situations. Each level presents unique obstacles and challenges that require innovative thinking and careful planning.

The game combines the satisfaction of engineering with the freedom of artistic expression, allowing players to draw any shape or structure they can imagine. With its intuitive controls and progressive difficulty system, Draw Bridge offers an accessible yet challenging experience for puzzle enthusiasts of all skill levels.

Core Features

Creative Bridge Construction

Become a master architect as you draw custom bridges to save vehicles in distress. The game's physics engine responds realistically to your creations, requiring you to consider weight distribution, structural integrity, and vehicle dynamics. Plan your moves strategically and utilize available resources efficiently to construct pathways that can safely support the car's journey.

Progressive Challenge System

Experience carefully crafted levels that gradually increase in complexity and difficulty. As you advance through the game, new obstacles emerge including spinning saws, moving platforms, unstable terrain, and multiple vehicles to rescue simultaneously. Each level introduces fresh mechanics that keep the gameplay exciting and unpredictable.

Intuitive Drawing Mechanics

The game features smooth, responsive drawing controls that make creating bridges feel natural and satisfying. Simply hold and drag your mouse to sketch any shape you envision - from simple straight bridges to complex multi-level structures with curves, supports, and creative engineering solutions.

Physics-Based Gameplay

Every line you draw becomes a solid structure subject to realistic physics. Watch as your bridges bend under weight, react to momentum, and interact with environmental hazards. This adds an extra layer of strategy as you must consider not just the path, but the structural soundness of your creations.

Gameplay Mechanics

The core gameplay revolves around analyzing each level's unique layout and obstacles, then drawing the most effective bridge design to guide the car safely to the finish flag. You'll need to account for:

  • Terrain gaps that require spanning with sturdy bridges
  • Moving hazards like spinning blades and falling objects
  • Weight limitations that affect bridge stability
  • Multiple vehicles in advanced levels requiring complex pathway systems
  • Resource management as some levels limit your drawing materials

Operation Guide

Getting started with Draw Bridge is simple:

  • Mouse Control : Hold and drag the left mouse button to draw bridges and pathways
  • Strategic Planning : Analyze the level layout before drawing your first line
  • Physics Consideration : Remember that your drawn structures must support the car's weight
  • Creative Solutions : Think outside the box - sometimes unconventional designs work best
  • Level Completion : Successfully guide the car to the red flag to advance

The beauty of Draw Bridge lies in its open-ended solutions. There's rarely just one correct answer, encouraging experimentation and creative problem-solving.

Why Play Draw Bridge

Draw Bridge stands out in the puzzle game genre by combining multiple engaging elements:

Educational Value : The game naturally teaches basic physics and engineering principles while entertaining players. It's an excellent way to develop spatial reasoning and problem-solving skills.

Creative Freedom : Unlike many puzzle games with rigid solutions, Draw Bridge encourages artistic expression and innovative thinking. Your unique approach to each challenge makes every playthrough personal.

Accessibility : The simple mouse controls and gradual learning curve make it perfect for players of all ages and experience levels. No complex tutorials needed - just start drawing!

Endless Replayability : With multiple solution paths for each level and the satisfaction of perfecting your designs, you'll find yourself returning to optimize and experiment with new approaches.
