Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Mine Line: Jetpack Digger**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Use a **"Toon Shaded" / Cell-Shaded** aesthetic to mimic the 2D sticker art style of the reference image. Objects should have bold, black outlines (implement via post-processing or inverted hull method). * **Character**: A low-poly, bright **Red Stickman/Robot** equipped with a metallic jetpack. The character must emit a continuous trail of white, puffy "smoke clouds" (sphere particles) from the jetpack as it moves. * **The World**: An infinite vertical scrolling grid representing the "Underground". * **Blocks**: Simple cubes representing dirt (brown), iron (grey), gold (yellow), and gems (blue). * **Lighting**: Ambient light + a Directional Light casting soft shadows. The deeper the player goes, the slightly darker the ambient light becomes (fog effect). * **Optimization**: Use `THREE.InstancedMesh` for the mining blocks to ensure 60FPS on mobile devices when rendering hundreds of rocks. ### 2. Audio Requirements * **BGM**: Fast-paced, rhythmic "Industrial Synth-Pop" track. It should feel energetic to match the jetpack speed. * **SFX**: * **Jetpack**: A continuous low-humming thrust sound (loops while moving). * **Mining**: A crunchy "rock smashing" sound. * **Combo**: A rising pitch sound effect (like a musical scale) for each rock added to the current "line/combo". * **Cash Register**: A "Cha-ching" sound when selling resources. ### 3. Gameplay Loop * **Core Mechanic**: The player constantly consumes "Fuel" to hover. The goal is to dig downwards. * **The "Line" System**: Unlike traditional mining games, the player does not stop to dig. Instead, when the player moves through a block, it doesn't break immediately. * The player must fly through **adjacent blocks of the same color** (e.g., 3 Gold blocks in a row) to form a "Line". * Once the chain is broken (player hits a different block or empty space), the "Line" detonates, granting resources and bonus score. * **Resource Management**: * Collected rocks automatically refill a small portion of Fuel. * Selling rocks at the surface (or via a UI button) grants Money to upgrade Jetpack Speed or Fuel Tank size. * **Game Over**: When Fuel reaches 0, the jetpack stops, and the run ends. ### 4. Mobile Controls & Interaction * **Orientation**: **Portrait Mode** (Vertical) to emphasize depth and digging. * **Control Scheme**: **Dynamic Virtual Joystick**. * The player touches anywhere on the bottom half of the screen to activate the joystick. * Dragging moves the character relative to the finger. * **Dash Mechanic**: A quick "Double Tap" on the screen performs a Dash (boost speed forward), useful for breaking through hard rock layers quickly. * **UI Layout**: * **Top Bar**: Depth Counter (in meters) and Score. * **Fuel Gauge**: A vertical bar on the left side of the screen (Green to Red gradient). * **Haptic Feedback**: Trigger a short vibration (`navigator.vibrate(20)`) every time a block is added to a combo line, and a long vibration when a combo detonates. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
