Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Global City: Metropolis Builder**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Create a vibrant, semi-realistic "SimCity-lite" aesthetic suitable for mobile screens. Use bright, saturated colors for buildings to make them pop against the terrain. * **Camera Perspective:** Implement an Isometric Camera view (OrthographicCamera in Three.js) fixed at a 45-degree angle, allowing players to see building depth without perspective distortion. * **Core Assets:** * **Terrain:** A grid-based tile system (green for grass, grey for roads, blue for water). * **Buildings:** Low-poly models representing: * *Residential:* Small houses, European-style townhouses, and large skyscrapers (Block of Flats). * *Industrial/Infrastructure:* Factories (with simple smoke particle effects), Water Towers, and Power Plants. * **Robot Assistant (Reference to Image):** Instead of a human UI helper, include a stylized, low-poly Yellow/Grey flying robot hovering in the corner or acting as the cursor guide for tutorials. * **Optimization:** Use instanced mesh rendering (InstancedMesh) for repeated objects like trees, road tiles, and small houses to ensure 60fps performance on mobile devices. ### 2. Audio Requirements * **BGM:** A calm, optimistic, and looping "City Building" soundtrack featuring acoustic guitar and light piano (similar to The Sims build mode or SimCity 3000 jazz) to encourage relaxed gameplay. * **Sound Effects (SFX):** * *Construction:* A satisfying "plop" or "hammering" sound when a building is placed. * *Collection:* A "coin jingle" or "cash register" sound when collecting taxes or resources. * *UI:* Soft "clicks" for menu selection; a "woosh" sound for camera zooming. * *Ambience:* Faint city sounds (distant traffic, birds chirping) dependent on the zoom level. ### 3. Gameplay Loop * **Core Cycle:** Produce Resources -> Build Structures -> Increase Population -> Collect Taxes -> Expand. * **Resource Management:** * Players tap factories to start production (Wood, Metal, Cement) and wait a few seconds/minutes for completion. * Resources are consumed to build residential zones. * **Growth Mechanics:** * Residential buildings generate "Coins" (Tax) over time. * Players must tap buildings with a coin icon above them to collect. * **Task System:** A "Mayor's Task List" UI panel on the left side that guides the player (e.g., "Build 3 Townhouses", "Collect 500 Coins"). Completing tasks grants premium currency or XP. ### 4. Mobile Controls & Interaction * **Touch Input:** * **Pan:** One-finger drag to move the camera across the map. * **Zoom:** Two-finger pinch to zoom in/out (adjusting the Orthographic camera zoom factor). * **Select/Build:** Single tap on a grid tile to open the build menu or collect resources. * **UI Layout (Portrait & Landscape Compatible):** * Floating Action Button (FAB) or a bottom dock for the "Build Menu". * Resource counters (Coins, Wood, Metal) pinned to the top header. * Buttons must be at least 44x44px for touch accessibility. * **Feedback:** * **Haptic:** Trigger a light vibration (navigator.vibrate) when placing a building or collecting taxes. * **Visual:** When resources are collected, show floating text (+100 Gold) rising from the building and fading out. ### 5. Code Structure & Language * Please output the complete, functional code in **English**. * Structure the code to handle window resize events gracefully for different device aspect ratios. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
