Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**One Line: Guardian Draw**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Low-poly 3D cartoon style with vibrant, saturated colors. The aesthetic should be fun and slightly spooky (inspired by the screenshot's Halloween theme) but approachable for all ages. * **Key Models**: * **Protagonist**: A stylized, defenseless character (e.g., a green-skinned "Frankenstein" teen or a simple stickman) with idle animations (shivering, looking around) and reaction animations (cowering in fear, cheering upon success). * **Antagonists/Hazards**: Low-poly purple Giants (holding boulders), swarms of bees (yellow particle systems), heavy rain clouds, or projectile turrets. * **The Line**: A dynamic, solid black mesh that extrudes in real-time as the player draws. It must look like thick ink or a steel beam. * **Environment**: * **Background**: A 2D stylized backdrop (purple night sky with a full moon and silhouette trees) or a simple 3D skybox. * **Ground**: A tiled stone platform with a grassy edge. * **Mobile Optimization**: * Use simple geometries (BoxGeometry, CylinderGeometry) for the line physics collider to save performance. * Limit dynamic lights to 1 (Directional Light with shadows) and use Ambient Light for fill. * Texture atlasing for character models to reduce draw calls. ### 2. Audio Requirements * **BGM**: A quirky, mischievous loop (pizzicato strings, woodwinds, and light percussion) that creates a sense of lighthearted urgency. * **Sound Effects (SFX)**: * **Drawing**: A "scribbling" or "chalk on board" sound that loops while the finger is touching the screen. * **Physics Impact**: Heavy "thuds" when boulders hit the ground or the line. Metallic "clangs" if the line hits the ground. * **Success**: A short, uplifting chime or fanfare after surviving 3 seconds. * **Failure**: A comical "womp-womp" or a gasp from the character. * **UI**: Soft "pops" for button clicks. ### 3. Gameplay Loop * **Phase 1: Observation**: The level starts frozen. The player sees the threat (e.g., Giant holding a rock) and the victim. * **Phase 2: Drawing**: The player draws a single continuous line on the screen. The physics simulation is paused while drawing. * **Phase 3: Simulation**: Once the player lifts their finger, the line turns into a physical object affected by gravity. The threat activates (Giant throws rock, bees attack). * **Win Condition**: The character must take **zero damage** for a countdown of **3 seconds**. * **Lose Condition**: The character is touched by a hazard, falls off the platform, or is crushed by the player's own drawn line. ### 4. Mobile Controls & Interaction * **Touch Input (Raycasting)**: * Map 2D touch coordinates (screen space) to 3D world space coordinates on a transparent plane located at the character's depth (Z-axis). * **Draw Action**: `touchstart` begins the line, `touchmove` extends the geometry, `touchend` finalizes the shape and triggers physics. * **Screen Orientation**: **Portrait Mode** preferred (to easily accommodate the "threat from above" verticality), but responsive design should center the camera on the action regardless of aspect ratio. * **UI Layout**: * **Top**: Level Progress bar and "Hint" button (lightbulb icon). * **Center**: The gameplay area (ensure it's not obscured by UI). * **Bottom**: "Restart" button (large tap target, >44px) for quick retries. * **Feedback**: * **Haptic**: Short vibration tick when the level starts simulating and a strong vibration if the player fails. * **Visual**: The countdown timer (3, 2, 1) should appear large on screen during the simulation phase. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About One Line

One Line is a captivating casual drawing game that combines creativity with quick thinking. Your mission is simple yet challenging: draw a single line to protect an unsuspecting man from a series of unfortunate events. From shielding him against heavy rain to fending off aggressive bees, angry giants, and falling boulders, each level presents unique obstacles that require creative solutions.

This physics-based puzzle game starts with simple challenges but gradually increases in complexity, testing your ability to think outside the box. The beauty of One Line lies in its simplicity - you only need one continuous line to solve each puzzle, but the possibilities are endless.

Core Features

Creative Problem Solving

Each level in One Line presents a unique scenario where the man faces different threats. Your drawn line can serve multiple purposes: - Shield : Block incoming projectiles like bullets or falling objects - Deflect : Redirect dangers away from the character - Create barriers : Build protective walls against various threats - Guide objects : Control the path of moving elements in the environment

Progressive Difficulty System

The game features a well-balanced difficulty curve that keeps players engaged: - Beginner levels : Simple protection scenarios to learn the basics - Intermediate challenges : Multiple threats requiring strategic planning - Advanced puzzles : Complex scenarios with moving elements and timing considerations - Expert levels : Multi-layered protection requiring precise line placement

Multiple Solution Approach

Unlike many puzzle games, One Line encourages experimentation. Most levels have multiple valid solutions, allowing players to: - Express their creativity through different drawing approaches - Develop personal problem-solving strategies - Replay levels to discover alternative solutions - Learn from failed attempts to improve their technique

Gameplay Mechanics

The core gameplay revolves around a simple yet powerful concept: you only need to keep the man safe for 3 seconds to complete each level . This time limit adds urgency while keeping the challenge manageable.

Drawing Physics

The game uses realistic physics simulation to make your drawings interactive: - Lines have physical properties and can support weight - Curved lines can deflect objects in different directions - Line thickness and angle affect protection effectiveness - Environmental elements interact naturally with your drawings

Threat Variety

One Line keeps gameplay fresh with diverse challenges: - Natural hazards : Rain, falling rocks, lightning strikes - Creature attacks : Angry bees, aggressive birds, wild animals - Human threats : Angry giants, projectile attacks - Environmental dangers : Collapsing structures, moving obstacles

Operation Guide

Basic Controls

  • Mouse/Touch : Drag to draw your protective line
  • Single continuous line : You can only draw one unbroken line per level
  • 3-second timer : Protect the man for exactly 3 seconds to win
  • Hint system : Use hints when stuck to see optimal solutions

Strategic Tips for Success

  1. Analyze the threat first : Understand what's coming before drawing
  2. Consider physics : Think about how objects will bounce or deflect
  3. Plan your line path : Visualize the entire line before starting to draw
  4. Use the environment : Incorporate existing structures into your protection strategy
  5. Experiment freely : Try different approaches if your first attempt fails

Advanced Techniques

  • Curved deflection : Use curved lines to redirect multiple threats
  • Structural support : Create load-bearing lines for heavy objects
  • Timing draws : Some levels require precise timing of your line placement
  • Multi-function lines : Design lines that serve multiple protective purposes
