Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Sprinter". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Replicate the iconic "Flash game" aesthetic: a minimalist, high-contrast look. Use a stark **white background** (void style) instead of a detailed stadium. * **Track**: Simple black parallel lines drawn on the white floor to simulate track lanes. No grass or crowd textures. * **Characters**: Low-poly 3D humanoid runners. * **Player Model**: Distinct bright color (e.g., Neon Blue shirt, White shorts). * **AI Opponents**: Distinct contrasting colors (e.g., Red/White, Green/Yellow). * **Animations**: Procedural or baked loop for "Sprinting" and a ragdoll or specific animation for "Stumbling/Falling" when the player fails the rhythm. * **Camera**: A dynamic chase camera positioned behind and slightly above the player. It should add a subtle "speed shake" effect when sprinting at max speed and lag slightly behind when the player accelerates quickly. * **Mobile Optimization**: Use simple geometries (BoxGeometry/CylinderGeometry) for characters if rigging is too complex for a single script, or load basic low-poly assets. No dynamic shadows; use simple circular "blob shadows" under characters to ensure 60fps on mobile. ### 2. Audio Requirements * **BGM**: A "Funky," upbeat, high-tempo MIDI-style track reminiscent of 2000s web games. It should loop seamlessly. * **Sound Effects (SFX)**: * **Footsteps**: A crisp, rhythmic "tap" sound every time the player successfully inputs a step. * **Stumble**: A comedic "slip" or "thud" sound when the player messes up the rhythm. * **Crowd**: A rising volume of cheering noise as the player approaches the finish line (100m mark). * **UI**: Standard start gun whistle/pistol sound. ### 3. Gameplay Loop * **Objective**: Win a 100m sprint against 3 AI opponents. * **Core Mechanic**: Rhythm-based acceleration. * The player gains speed by successfully alternating inputs (Left -> Right -> Left). * **Failure State (Stumble)**: If the player taps the same side twice in a row (e.g., Left -> Left) or taps too frantically without rhythm, the character triggers a "Stumble" state, losing all momentum and falling flat for 1.5 seconds before getting up. * **Progression**: The game consists of rounds. Round 1 is slow (School level), Round 2 is High School, Round 3 is Olympic, Round 4 is Alien/Superhuman. The AI speed increases with each round. * **Win/Loss**: Crossing the line 1st advances to the next level. Crossing 2nd or lower triggers a "Game Over - Try Again" screen. ### 4. Mobile Controls & Interaction * **Control Scheme**: **Split-Screen Tapping**. * Divide the screen invisibly into two vertical halves. * **Tap Left Half of Screen**: Simulates Left Foot step. * **Tap Right Half of Screen**: Simulates Right Foot step. * **Orientation**: **Landscape Mode** is mandatory to allow thumbs to comfortably reach both sides of the screen. * **Feedback**: * **Visual**: Small dust particle bursts at the character's feet on every successful tap. * **Haptic**: Short vibration (10ms) on successful step; Long vibration (200ms) on stumble. * **UI Layout**: * Top Center: Distance meter (e.g., "80m to go"). * Touch Areas: The entire left and right sides of the screen should be active touch zones, no small buttons. * Start/Retry Button: Large, centered, green button (at least 88px height) for easy restarting. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.

Game Introduction

About the Game

Sprinter is a timeless classic running game that captures the pure excitement of 100-meter sprint racing. In this fast-paced competition, you'll face off against computer-controlled opponents who become progressively faster and more challenging as you advance through different racing levels.

The game's charm lies in its perfect balance of simplicity and skill-based gameplay. While the concept is straightforward - run faster than your opponents - mastering the precise timing required for optimal sprinting creates an addictive and rewarding experience.

Core Features

Simple Yet Challenging Gameplay

Sprinter proves that the best games often have the most elegant mechanics. Using just the left and right arrow keys, you'll need to develop a rhythmic tapping technique that builds momentum without causing your sprinter to stumble. The challenge intensifies as you progress through career levels, each representing more serious competitive events.

Progressive Difficulty System

What makes Sprinter particularly engaging is its well-designed difficulty curve. Early races allow you to learn the fundamentals, while later competitions feature opponents with lightning-fast speeds that will test your finger dexterity and timing precision to the limit.

Unique Audio Experience

Each racing level features its own distinctive, funky soundtrack that perfectly complements the on-screen action. The groovy music tracks add personality to each race and help maintain the game's upbeat, energetic atmosphere.

Quick Gaming Sessions

Perfect for short breaks, Sprinter can be completed in just a few minutes, making it an ideal choice when you need a quick gaming fix or want to squeeze in some competitive fun during a busy day.

Gameplay Mechanics

The core gameplay revolves around mastering the art of alternating between the left and right arrow keys at the optimal speed. Too slow, and your opponents will leave you in the dust. Too fast or poorly timed, and your sprinter will lose balance and stumble, costing precious seconds.

Success requires finding that perfect rhythm - fast enough to build maximum speed, but controlled enough to maintain stability throughout the entire 100-meter race. Each level presents a new challenge as opponent speeds increase, forcing you to continually refine your technique.

Operation Guide

Basic Controls

  • Left Arrow Key : Left leg stride
  • Right Arrow Key : Right leg stride
  • Mouse Click : Activate game if arrow keys aren't responding

Racing Strategy

  1. Start with a steady, controlled rhythm to build initial momentum
  2. Gradually increase your tapping speed as your sprinter gains confidence
  3. Watch your runner's form - stumbling indicates you're going too fast
  4. Maintain consistent timing rather than random rapid clicking
  5. Focus on smooth, alternating key presses for optimal performance

Pro Tips

  • Practice finding your optimal tapping rhythm in early levels
  • Pay attention to your sprinter's animation to gauge proper timing
  • Don't panic when opponents seem faster - consistency wins races
  • Each level's music can help you maintain a steady rhythm
