Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**One Line Draw**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a clean, minimalist 2D aesthetic simulated within a 3D Three.js environment (orthographic camera). The background should be a subtle, light graph paper texture (grid pattern) to emphasize the "sketching/planning" theme. * **Key Elements:** * **Nodes (Vertices):** Render nodes as distinct, colorful spheres or flat circles (e.g., bright blue with a thin black outline). * **Paths (Edges):** Unvisited paths should be dark grey lines. Visited paths should light up in a vibrant color (e.g., golden yellow or neon orange) as the player traces over them. * **Cursor/Touch Trail:** Add a soft, glowing particle trail following the user's touch point to indicate the current drawing position. * **Optimization:** Since this is a puzzle game, keep geometry simple (low-poly spheres or simple circular sprites). Ensure high-resolution rendering on mobile screens (handle `devicePixelRatio`). ### 2. Audio Requirements * **BGM:** A calm, lo-fi hip-hop or acoustic guitar track that promotes focus and relaxation. It should be unobtrusive and loop seamlessly. * **Sound Effects (SFX):** * **Connection:** A satisfying "pop" or high-pitched "ding" when the line successfully snaps to a new node. * **Error:** A dull "thud" or buzz if the player tries to retrace a line or moves to an unconnected area. * **Completion:** A cheerful, ascending melodic chime or chord when the entire shape is successfully completed. * **UI:** Soft clicks for menu buttons. ### 3. Gameplay Loop * **Objective:** The player must connect all nodes in a geometric shape using a single continuous line. * **Rules:** 1. The player starts by touching any node. 2. They drag their finger/cursor to an adjacent connected node. 3. Once a line segment is traversed, it changes color and cannot be traversed again. 4. The player *cannot* lift their finger (or release the mouse) until the puzzle is solved or they want to reset the current attempt. * **Win Condition:** All defined edges in the graph are traversed exactly once. Upon winning, trigger a particle confetti explosion and display a "Level Complete" overlay. * **Fail/Reset Condition:** If the player gets stuck (no unvisited edges remaining but the puzzle isn't finished), they must release to reset the level. ### 4. Mobile Controls & Interaction * **Touch Input:** Implement a robust touch-and-drag system (`touchstart`, `touchmove`, `touchend`). * **Raycasting:** Use a Raycaster to detect which node is currently under the user's finger. * **Snap Assist:** To make mobile play comfortable, the line drawing shouldn't require pixel-perfect precision. If the finger is *near* a valid connected node, the line should visually "snap" to that node. * **Orientation:** Design for **Portrait Mode** by default, as this is a logic puzzle often played with one hand. * **UI Layout:** * Place a "Reset" button and a "Hint" button at the bottom of the screen (easy thumb reach). * Ensure buttons have a minimum touch target of 44x44px. * **Feedback:** * **Haptic:** Trigger a short, light vibration (using `navigator.vibrate`) whenever a node is successfully connected. * **Visual:** The currently active node should pulse slightly to indicate it's the anchor point. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About One Line Draw

One Line Draw is a captivating puzzle game that combines logic, strategy, and artistic thinking into one seamless experience. The concept is beautifully simple yet intellectually challenging: complete each geometric pattern using exactly one continuous line without lifting your finger or retracing any path.

This brain-training game features clean, minimalist graphics with colorful geometric shapes that create visually appealing puzzles. Each level presents a unique pattern made up of connected dots and lines, challenging you to find the perfect starting point and route to complete the entire figure in one stroke.

Core Features

Simple Yet Challenging Gameplay

The game's elegance lies in its simplicity. With just a click-and-drag mechanic, you'll navigate through increasingly complex geometric patterns that test your logical thinking and planning abilities.

Brain Training Benefits

One Line Draw serves as excellent mental exercise, improving: - Spatial reasoning skills - Strategic planning abilities - Pattern recognition - Problem-solving techniques - Concentration and focus

Progressive Difficulty

Start with simple triangles and squares, then advance to complex polygons, stars, and intricate geometric designs. Each level builds upon previous concepts while introducing new challenges.

Clean Visual Design

The game features a minimalist aesthetic with bright, contrasting colors that make patterns easy to see and analyze. The clean interface ensures nothing distracts from the puzzle-solving experience.

Gameplay Mechanics

Core Rules

  • Draw one continuous line to complete the entire pattern
  • Cannot lift your finger or mouse during drawing
  • Cannot retrace any line segment
  • Must visit every line in the pattern exactly once
  • Find the optimal starting point for each puzzle

Strategic Elements

Success requires careful analysis before making your first move. Study the pattern, identify potential starting points, and mentally trace possible paths. Some patterns have multiple solutions, while others have only one correct route.

How to Play

Getting Started: 1. Analyze the geometric pattern presented 2. Identify all connection points and line segments 3. Plan your route mentally before starting 4. Click and hold on your chosen starting point 5. Drag your mouse or finger to draw the continuous line 6. Complete the entire pattern without lifting or retracing

Pro Tips: - Count the number of lines connected to each dot - Dots with odd numbers of connections are potential start/end points - Practice with simpler patterns before attempting complex designs - Take your time to analyze before drawing
