Please use Three.js to generate a **mobile-first game** with the theme "**Sprint League: Ultimate Runner**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Implement a vibrant, "Low-poly Cartoon" aesthetic similar to popular Roblox or .io games. Characters should be "chibi" style—large heads, small bodies, expressive faces—wearing green tracksuits (inspired by Squid Game) or customizable athletic gear. * **Scene Layout:** * **Main Hub:** A gym-like area with rows of treadmills ranging from rusty beginner machines to high-tech neon ones. * **Race Tracks:** Linear tracks floating in a stylized void (purple/blue gradient background) or stadium setting. Tracks should have distinct lanes (wood, rubber, neon glowing) and obstacles. * **Performance Optimization (Mobile Priority):** * Use geometry instancing for repeated objects (treadmills, coins, spectators). * Limit dynamic light sources; use baked lighting or simple ambient + directional light setup. * Characters should use low-polygon meshes (under 1500 tris) with simple texture atlases. * Implement object pooling for particle effects (sweat drops, speed lines, coin sparkles). ### 2. Audio Requirements * **BGM:** * *Training Mode:* Upbeat, repetitive Lo-fi hip hop or Synth-pop to encourage grinding. * *Race Mode:* High-tempo, adrenaline-pumping electronic dance music (EDM) with a driving bassline. * *Tension Mode (Red Light/Green Light):* Minimalist eerie ticking sounds mixed with silence. * **Sound Effects (SFX):** * *Running:* Rhythmic footstep sounds that change pitch based on speed (treadmill whirring vs. track thuds). * *UI:* Satisfying "pop" or "cash register" sounds when collecting coins or upgrading stats. * *Feedback:* A cartoonish "boing" or "splat" sound when colliding with obstacles or getting tagged. ### 3. Gameplay Loop * **Core Mechanics (The Grind):** * **Training Phase:** The player stands on a treadmill. Tapping the screen rapidly fills a "Speed Bar" or "Stamina Bar." The faster the tap, the more XP/Speed points gained. * **Race Phase:** Once trained, the player enters a race against NPC bots. Movement is automatic forward; player steers left/right to avoid obstacles and collect coins. Speed is determined by the stats gained in the Training Phase. * **Game Modes:** * *Classic Race:* Reach the finish line first. * *Red Light, Green Light:* Move only when the giant doll is turned away; stop instantly on Red. Failure = Reset. * *Tung Tung Tag (Chase Mode):* Run away from a boss character ("Tung Tung"). Collect coins while evading capture. Being caught converts the player to the chaser team (change character color to red). * **Progression:** Coins collected unlock better treadmills (higher XP multiplier), faster shoes, and cosmetic skins. ### 4. Mobile Controls & Interaction * **Control Scheme:** * *Training:* **Rapid Tap** anywhere on the screen to run on the treadmill. * *Racing/Tag:* **Virtual Joystick** (bottom center, dynamic positioning) for 360-degree movement, OR a simple **Slide-to-Steer** mechanic for lane changing. * **Orientation:** **Portrait Mode** (Vertical) is preferred for one-handed "casual" play, focusing on the character's back view. * **Haptic Feedback:** Trigger short vibration pulses when collecting coins and a long, heavy vibration when crashing or getting tagged. * **UI/UX:** * Large, thumb-friendly buttons (min 48px height) for "Upgrade," "Race," and "Shop." * Floating text indicators (+1 Speed, +10 Coins) that animate upward and fade out to provide instant gratification.
