Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Idle World". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** High-quality **Voxel Art** (3D Pixel style). The core focus is a central, rotating spherical planet made of small distinct cubes (voxels), similar to a "Minecraft planet" but spherical. * **The Planet:** * Start as a barren, rocky lava sphere (red/orange voxels). * As the player progresses, voxels change color dynamically: Blue (Water), Green (Forests), Brown (Mountains), White (Ice caps/Clouds). * Use **InstancedMesh** for the voxels to ensure 60FPS on mobile devices even with hundreds of cubes. * Add a custom shader or a glowing transparent outer sphere to simulate an **Atmosphere/Halo effect**. * **Background:** Deep space environment. Dark blue/black gradient background with a slowly rotating starfield particle system. Add 1-2 distant, non-interactive planets (like a red Mars or ringed Jupiter) in the background parallax for depth. * **Particles:** Floating text ("+1 Energy") that appears on tap and floats upwards before fading out. ### 2. Audio Requirements * **BGM:** Ethereal, ambient space synthesizer music. Slow tempo, relaxing, promoting a sense of cosmic scale and evolution. Similar to "Stellaris" or "Spore" ambient tracks. * **Sound Effects (SFX):** * **Tap/Gather:** A soft, satisfying "pop" or high-pitched "blip" sound when the user taps the planet. * **Upgrade:** A harmonious "chime" or "ding" chord when purchasing a new element (e.g., creating the first ocean). * **Ambience:** Subtle wind or ocean wave white noise as the planet evolves. ### 3. Gameplay Loop * **Core Mechanic:** The game starts with a "Big Bang." The player taps the screen to generate **Energy**. * **Economy & Growth:** * **Currency:** Energy (generated by tapping and passive generation). * **Upgrades:** Spend Energy to buy "Evolutionary Steps": 1. *Cooling:* Turns lava voxels into stone. 2. *Atmosphere:* Adds clouds/glow. 3. *Water:* Turns low-elevation voxels blue. 4. *Life:* Spawns trees (green voxels popping up) and eventually buildings. * **Automation:** Unlocking "Life" generates passive Energy per second (EPS), allowing the game to play itself (Idle). * **Visual Progression:** The planet must visually transform based on upgrades purchased (e.g., buying "Water" instantly changes 40% of the red cubes to blue). ### 4. Mobile Controls & Interaction * **Camera Control (OrbitControls):** * **One-finger swipe:** Rotates the planet (Orbital view). Ensure `enableDamping` is true for smooth momentum. * **Pinch:** Zoom in/out (clamped to prevent going inside the planet or too far out). * **Interaction:** * **Tap:** Tapping *anywhere* on the screen (except UI) counts as "gathering energy." * **Raycasting:** If the user taps a specific voxel, highlight it briefly to show responsiveness. * **UI Layout (Portrait Mode Preferred):** * **Top 20%:** Resource counters (Energy, EPS) with large, readable fonts. * **Middle 50%:** Viewport for the 3D Planet. * **Bottom 30%:** Scrollable upgrade panel. Buttons must be large (minimum 44px height) for easy thumb pressing. * **Haptic Feedback:** Trigger a light vibration (`navigator.vibrate(5)`) on every tap to simulate the physical impact of shaping the world. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
