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:** A stylized, vibrant **isometric city-builder**. While the gameplay is grounded in reality (flats, roads), the visual aesthetic should take inspiration from the provided screenshot's color palette: deep ocean blues for the background/skybox and bright yellow/gold highlights for UI and active elements. * **Camera:** Use an **Orthographic Camera** to provide a classic tycoon simulation view. * **Models (Low-Poly for Mobile):** * **Ground:** A grid-based tile system (green for land, grey for roads, blue for water). * **Buildings:** Distinct low-poly placeholders for: * *Residential:* "Block of flats" (Tall, rectangular, white/beige). * *Industrial:* "Factories" (Smoke stacks, brick red). * *Infrastructure:* Roads (connectable tiles). * **Avatar/Mascot:** Include a simple 3D representation (or 2D sprite billboard) of a **Yellow Robot/Mecha** (referenced from the screenshot) that acts as the "City Advisor" floating near the UI to give tasks. * **Lighting:** Ambient light (soft white) + Directional light (simulating sunlight) to cast soft shadows for depth. * **Performance:** Use `InstancedMesh` for repeated objects (like trees or road blocks) to maintain 60FPS on mobile devices. ### 2. Audio Requirements * **BGM:** A relaxing, looping "Sim-style" acoustic track with light jazz elements (piano and soft bass) to encourage long play sessions. * **Sound Effects (SFX):** * *Construction:* A satisfying "Pop" or "Construction thud" when a building is placed. * *Collection:* A "Coin jingle" when collecting taxes or resources. * *UI:* Soft "Clicks" for menu navigation. * *Level Up:* A futuristic "Jetpack whoosh" sound (referencing the robot image) when the city levels up. ### 3. Gameplay Loop * **Core Mechanic:** The player starts with an empty grid and a "Task Sheet". * **Cycle:** 1. **Build:** Select a building type (House/Road/Factory) from the UI and tap a grid tile to place it (costs money). 2. **Produce:** Factories produce "Materials" over time; Houses produce "Population" and "Tax Coins". 3. **Collect:** Tap buildings with icons floating above them to collect resources. 4. **Expand:** Use resources to complete "City Tasks" (e.g., "Build 3 Houses") displayed by the Robot Advisor. * **Victory/Progression:** Completing tasks increases the "City Level." The goal is to maximize population count. * **Guidance:** Implement a "3D Arrow" that points to the next recommended action (as described in the text: "Follow the arrows"). ### 4. Mobile Controls & Interaction * **Camera Controls:** * **Pan:** One-finger drag to move the camera across the map. * **Zoom:** Two-finger pinch to zoom in/out (clamp the zoom levels). * **Interaction (Raycaster):** * **Tap:** Select a building to view details or collect resources. * **Drag-and-Drop Building:** When in "Build Mode," dragging a ghost building over the grid snaps it to tiles; lifting the finger confirms placement. * **UI Layout (Portrait Mode Preferred):** * **Bottom HUD:** A scrollable carousel for building selection (44px min height for touch targets). * **Top HUD:** Resource counters (Coins, Population, Materials). * **Task Button:** A floating button on the left featuring the Robot icon to open the current quest. * **Feedback:** Trigger `navigator.vibrate(50)` (Haptic Feedback) when a building is successfully placed or resources are collected. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
