Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Stair Jump". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Minimalist "2.5D" Neon Arcade style. The game looks like a side-scroller but uses 3D geometries. * **Color Palette**: High contrast against a deep black background (`#000000`). * **Player**: A glowing blue sphere (`#4444ff`, emissive). * **Stairs**: Neon green rounded cubes (`#00ff00`). Use `BoxGeometry` with slightly beveled edges or textures that simulate roundness. * **Spikes**: Bright neon green cones (`ConeGeometry`) placed on top of specific stairs. * **Collectibles**: Spinning yellow stars (`#ffff00`, `OctahedronGeometry` or `StarShape`). * **Power-ups**: Special stair blocks with a "Blue Arrow Down" texture, acting as jump pads. * **Camera**: Use an **Orthographic Camera** to maintain a consistent 2D gameplay perspective without perspective distortion. The camera must smoothly follow the player's vertical and horizontal progress (Lerp). * **Mobile Optimization**: * Use `InstancedMesh` for the stair blocks and spikes to handle infinite procedural generation without performance drops on mobile devices. * Implement an object pooling system for particles and stars. * Limit light sources; rely on `MeshBasicMaterial` or `MeshStandardMaterial` with high `emissive` values to simulate a "glow" without expensive post-processing bloom, or use a very lightweight `UnrealBloomPass` if performance allows. ### 2. Audio Requirements * **Background Music (BGM)**: A fast-paced, looping "Chiptune" or "Synthwave" track that encourages rhythm and speed. * **Sound Effects (SFX)**: * **Jump**: A short, rising synthesized "woosh" or "blip". * **Landing**: A soft, low-frequency "thud" when the ball touches a step. * **Star Collection**: A high-pitched, satisfying "ding" or coin sound (essential for dopamine feedback). * **Death**: A "shattering" glass sound or a digital "crunch" noise. * **Power-up**: A rapid ascending scale sound. ### 3. Gameplay Loop * **Core Mechanic**: Endless vertical climbing. The player controls a ball that constantly bounces (physics-based) on stairs arranged diagonally (up and to the right). * **Physics Logic**: * The ball has constant gravity. * **Auto-Bounce**: If the ball lands on a safe stair, it automatically bounces vertically slightly. * **Player Input**: Clicking adds a significant horizontal and vertical impulse (Vector3), propelling the ball to the next step. * **Obstacles & Difficulty**: * **Spikes**: Stationary hazards on steps. Contact = Instant Game Over. * **Gaps**: Missing steps requiring double-taps or precise timing to cross. * **Moving Blocks**: Some stairs move horizontally (left/right), requiring timing to land. * **Scoring**: * Score is based on **Stars Collected**, NOT distance traveled. * Stars are placed slightly off the optimal path or above dangerous spikes to create risk/reward scenarios. * **Win/Loss**: * **Loss**: Touching a spike or falling off the screen (y-position < camera threshold). * **Restart**: Instant restart upon tapping the "Game Over" screen (no loading times). ### 4. Mobile Controls & Interaction * **Controls**: Single-input system. * **Tap Anywhere**: Apply impulse to the ball. * **Double Tap**: Optional mechanic for a mid-air jump if the game physics allows, or simply rapid tapping to traverse long distances. * **Screen Orientation**: Portrait Mode (Vertical) preferred to see upcoming stairs, but responsive to Landscape. * **UI/UX**: * **HUD**: Large, bold text for the Score (Top Center). * **Start/Restart**: A large, pulsing "Tap to Start" overlay. * **Feedback**: * **Screenshake**: Subtle camera shake when hitting a spike or dying. * **Particles**: A small explosion of blue particles (cubes) when the player dies. * **Trail**: A faint ribbon trail following the ball to emphasize speed.

Game Introduction

About the Game

Stair Jump is an engaging physics-based clicker game that combines simple controls with challenging gameplay. With a solid 4.2/5 rating from players, this game offers endless entertainment as you guide a bouncing ball up an infinite staircase filled with obstacles and collectible stars.

The premise is deceptively simple: click to make your ball jump forward and climb the stairs. However, what starts as an easy task quickly becomes a thrilling challenge as you encounter spikes, moving blocks, and other obstacles designed to knock you back down.

Core Features

Simple One-Click Gameplay

Stair Jump's beauty lies in its simplicity. With just single clicks or taps, you control your ball's movement up the staircase. The intuitive controls make it perfect for quick gaming sessions on any device.

Physics-Based Movement

The game features realistic physics mechanics where your ball responds naturally to gravity and momentum. Each click propels the ball forward, but timing and precision are crucial for navigating obstacles successfully.

Challenging Obstacle System

Navigate through various obstacles including: - Sharp spikes that end your run instantly - Moving blocks that require precise timing to avoid - Power-up stairs with blue arrows that boost your jumping ability - Narrow passages that test your precision

Star Collection System

Your score depends on collecting stars scattered throughout the staircase, not just climbing higher. This scoring system encourages exploration and risk-taking, as the most valuable stars are often in dangerous positions.

Cross-Platform Compatibility

Built with HTML5 technology, Stair Jump runs smoothly on: - Desktop computers and laptops - Smartphones and tablets (iOS and Android) - All modern web browsers - No download or installation required

Game Mechanics

Scoring System

Unlike traditional climbing games, your score in Stair Jump is determined by the number of stars you collect, not the height you reach. This unique scoring mechanic encourages players to take calculated risks and explore different paths up the staircase.

Power-Up Mechanics

Look for special stairs marked with blue downward-facing arrows. These power-up stairs provide enhanced jumping ability, allowing you to clear larger gaps and reach otherwise inaccessible areas.

Speed vs. Safety Balance

The game rewards both speed and precision. Moving quickly allows you to collect more stars in a shorter time, but rushing increases the risk of hitting obstacles. Finding the right balance is key to achieving high scores.

How to Play

Basic Controls

  • Mouse : Click anywhere on the screen to make the ball jump forward
  • Touch : Tap the screen on mobile devices
  • Timing : The ball falls naturally due to gravity, but each click propels it forward

Gameplay Strategy

  1. Start Slow : Begin with careful, measured clicks to understand the physics
  2. Watch for Patterns : Observe moving obstacle patterns before attempting to pass
  3. Prioritize Stars : Focus on collecting stars rather than just climbing height
  4. Use Power-ups : Take advantage of blue arrow stairs for difficult sections
  5. Practice Timing : Master the rhythm of clicking for optimal momentum

Advanced Tips

  • Study obstacle patterns before making risky moves
  • Use power-up stairs strategically for difficult sections
  • Don't rush - consistency beats speed in most situations
  • Learn from each attempt to improve your strategy
