Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Sprint League: Idle Runner & Tag**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Low-poly, vibrant cartoon aesthetic similar to Roblox or .io games. Characters should be chibi-style with oversized heads and expressive faces. Use bright, saturated colors (especially the signature "Squid Game" green for tracksuits and purple for the background). * **Environment Construction:** * **Main Hub (Gym):** An open area with rows of treadmills ranging from rusty manual ones to high-tech glowing futuristic machines. * **Race Tracks:** Linear tracks for competitive sprinting with colorful lanes. * **"Red Light, Green Light" Zone:** A dusty arena with a large robotic doll figure at the far end. * **Tag Arena:** An open map with obstacles for the "Tung Tung Tag" mode. * **Performance Optimization (Mobile First):** * Use simple geometry (box/cylinder primitives) for environments to keep draw calls low. * Implement object pooling for coins and particle effects (sweat drops, speed lines). * Use baked lighting maps instead of real-time shadows where possible. * Textures should be compressed (1024x1024 max for atlases). ### 2. Audio Requirements * **Background Music (BGM):** * **Training Mode:** Upbeat, repetitive "elevator" style synth-pop loops to encourage grinding. * **Race/Tag Mode:** Fast-paced, high-BPM electronic track with urgent drum beats. * **Red Light Mode:** Tense silence interspersed with the iconic "Red Light, Green Light" vocal cue (or a soundalike melody), followed by sudden loud chaotic music when running. * **Sound Effects (SFX):** * **Footsteps:** Rapid "tap-tap-tap" sounds varying by surface (treadmill rubber vs. dirt). * **Collection:** Satisfying "ching" or "pop" sound when collecting coins/points. * **UI:** Soft clicks for upgrades, loud fanfare for leveling up. * **Tag Mode:** A comedic "boing" or impact sound when tagged. ### 3. Gameplay Loop * **Phase 1: The Idle Grind (Training):** * The player stands on a treadmill. Tapping the screen (or holding) increases running speed and generates "Stamina Points." * **Progression:** Use Stamina Points to upgrade "Speed," "Endurance," and unlock faster treadmills (which yield higher points per second). * **Phase 2: The Race (Competition):** * Once enough Stamina is banked, the player enters a Race against AI bots. * **Mechanic:** Auto-run, but the player must tap rhythmically or react to Quick Time Events (QTE) to maintain boost. Winning earns "Coins." * **Phase 3: The Mini-Games (Modes):** * **Red Light, Green Light:** Hold screen to run, release instantly when the indicator turns red. Failure results in a ragdoll "elimination" restart. * **Tung Tung Tag:** A chase mode. Run away from the "Tung Tung" chaser AI. Collect coins spawned on the map while evading. If tagged, the player transforms (visual change) and the round ends. * **Economy:** Spend Coins on cosmetic skins (shoes, hats, tracksuits) and permanent stat multipliers. ### 4. Mobile Controls & Interaction * **Orientation:** Portrait Mode (Vertical) for one-handed idle training; Landscape Mode (Horizontal) optional for Tag/Racing, but Portrait is preferred for hyper-casual consistency. * **Control Scheme:** * **Training:** Rapid Tapping anywhere on the screen to sprint; Long Press to auto-run (upgradeable feature). * **Movement (Tag/Race):** A floating **Virtual Joystick** on the bottom center/left of the screen for 360-degree movement. * **UI/UX:** * Large, thumb-friendly buttons (min 48dp/44px) for "Upgrade," "Race," and "Shop" located at the bottom of the screen. * **Haptic Feedback:** Short vibration bursts when collecting coins, bumping into obstacles, or getting tagged. * **Visual Feedback:** Floating text ("+1 Speed", "Perfect!") appearing near the character. Screen shake effect on high-speed sprints. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
