Idle Light City - City Management Game
Prompt
MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Idle Light City". Please read the following detailed game design requirements first, and then generate the code accordingly:
### 1. Assets & Environment
* **Visual Style:** A cute, Low-poly 3D aesthetic with a cartoonish vibe. The color palette should focus on high contrast: deep blues and purples for the unlit city/background (representing darkness) and warm, glowing oranges and yellows for the lightbulbs and illuminated buildings.
* **Key Models:**
* **The Lightbulbs (Citizens):** Anthropomorphic lightbulb characters with small legs and faces (like the reference image), glowing with an Emissive material.
* **The Factory:** A central building where lightbulbs spawn.
* **Residential Buildings:** Simple low-poly houses that start dark/gray and turn bright/colorful when "lit."
* **The Ground:** A grid-based street layout.
* **Lighting & Effects:** Use a dark ambient light with localized PointLights attached to each active lightbulb character. Implement a "glow" effect (bloom post-processing) to make the lightbulbs pop against the dark background.
* **Mobile Optimization:** Use `InstancedMesh` for the lightbulb characters to handle hundreds of units on screen without lag. Limit real-time shadows to the main factory area.
### 2. Audio Requirements
* **BGM (Background Music):** A relaxing, "Lo-Fi" night-time beat. It should start minimal (bass and soft synth) and layer in more melody/energy as more of the city becomes illuminated.
* **Sound Effects (SFX):**
* **Spawn:** A satisfying soft "pop" or "bloop" sound when a lightbulb leaves the factory.
* **Lighting Up:** An electrical "hum" or light switch "click" sound when a lightbulb enters a house.
* **UI/Upgrades:** A high-pitched "cha-ching" or coin sound for purchasing upgrades.
* **Ambience:** Subtle night sounds (crickets, distant wind) when the city is idle.
### 3. Gameplay Loop
* **Core Mechanic:** The central factory automatically spawns walking Lightbulb characters at a set interval. These characters pathfind along the roads to nearby houses.
* **Objective:** When a lightbulb reaches a dark house, the house lights up. When a lightbulb reaches an already lit house, it generates currency (Money/Watts) and despawns (returning to the pool).
* **Active Clicker Element:** Tapping on the Factory building instantly spawns a lightbulb (bypassing the auto-spawn timer), encouraging active play.
* **Progression & Upgrades:** Players spend currency to:
1. **Unlock New Buildings:** Expand the city grid.
2. **Upgrade Production:** Increase auto-spawn speed.
3. **Upgrade Capacity:** Increase the maximum number of lightbulbs allowed on streets.
4. **Upgrade Profit:** Increase money earned per house visited.
### 4. Mobile Controls & Interaction
* **Screen Orientation:** **Portrait Mode** (Vertical) to allow for easy one-handed play.
* **Camera Control:** Isometric view (45-degree angle). Implement single-finger drag to Pan the camera around the city and two-finger pinch to Zoom.
* **Touch Input (Raycaster):**
* **Tap Factory:** Rapidly spawns units.
* **Tap UI Buttons:** Large, thumb-friendly buttons (minimum 44px height) docked at the bottom of the screen for Upgrades.
* **Feedback Systems:**
* **Haptics:** Trigger a short vibration (using `navigator.vibrate`) when tapping the factory or buying an upgrade.
* **Floating Text:** Show floating numbers ("+$10") rising from houses when money is earned to provide immediate visual reward.
Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
