MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Sandbox City: Mobile Outbreak**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a vibrant **Low-Poly** 3D aesthetic (similar to "Synty Studios" assets). Use flat shading or simple gradient textures to ensure high performance on mobile devices. * **Character Models:** Blocky, stylized humanoids with distinct segments (head, torso, limbs) to facilitate **Ragdoll Physics**. Differentiate Zombies (green skin/ragged clothes) from Civilians (suits, casual wear). * **City Environment:** A modular urban grid containing intersections, traffic lights, "Hot Pizza" shops, and simple rectangular skyscrapers. The color palette should be saturated and sunny (bright blue sky, yellow taxis, grey asphalt). * **Performance Optimization:** Use instanced rendering for repetitive elements (trees, streetlamps). Limit dynamic light sources; rely on a high-quality ambient/hemisphere light and one main directional light (sun) with shadow mapping. ### 2. Audio Requirements * **BGM:** An energetic, arcade-style looped track (upbeat synth-rock) that keeps the pacing high. * **Sound Effects (SFX):** * **Combat:** Cartoonish "thud" and "whack" sounds for melee; arcade-style "pew-pew" or realistic pops for gunfire. * **Vehicles:** Engine revving loops (pitch shift based on speed), tire screeching on drifts. * **Feedback:** A comical "boing" or heavy impact sound when a character goes into ragdoll mode. ### 3. Gameplay Loop * **Core Mechanics:** The player controls a survivor in a third-person view. The goal is to roam the city and eliminate zombies before they infect the entire population. * **Dynamic States:** The player can switch between **On-Foot** (combat/movement) and **Driving** (hijacking any car on the street). * **Physics & Chaos:** Implement a physics engine (like Cannon.js) to handle vehicle collisions and character ragdolls. When a zombie is hit by a car or heavy weapon, they should flail comically through the air. * **Infection System:** Zombies should actively chase nearby civilians. If a civilian is touched, they turn into a zombie after 3 seconds, increasing the difficulty dynamically. ### 4. Mobile Controls & Interaction * **Orientation:** **Landscape Mode** is mandatory for the open-world field of view. * **Touch Controls (On-Foot):** * **Left Zone:** Virtual floating joystick for character movement (WASD logic). * **Right Zone:** Swipe to rotate camera/aim. * **Action Buttons:** Large circular buttons (min 64px) on the bottom right for "Attack/Shoot" and "Jump." * **Touch Controls (Driving):** * UI changes when inside a car: Left/Right arrows for steering, Gas/Brake pedals on the right. * **Context-Sensitive Interaction:** Create a dynamic "Interact" button that appears *only* when near a valid object (e.g., changes to a "Car Door" icon when near a vehicle, or a "Shop" icon near a store). * **Feedback:** Implement `navigator.vibrate()` for haptic feedback when taking damage or crashing a car. Add screen shake for explosions or heavy impacts. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
