Please use Three.js to generate a **mobile-first game** with the theme "**Basketball Line - Physics Drawing Puzzle**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** 2.5D Aesthetic. Use a clean, flat, vector-art inspired style similar to the reference image but in a 3D space. * **Background:** A soft, neutral grey or off-white paper texture background to simulate a drawing pad. * **The Ball:** A 3D sphere with a classic orange basketball texture, but with bold, cel-shaded outlines (toon shader) to match the cartoon look. * **The Pencil:** A stylized 3D model of a pencil (blue body, wood tip, red eraser) that follows the user's input pointer. It should slightly tilt based on the drawing direction. * **The Line:** The lines drawn by the player should be extruded 3D tubes (blue color) with a smooth, matte finish, appearing instantly as the finger drags across the screen. * **The Hoop:** A stylized 3D hoop with a net that reacts to physics (cloth simulation or simple joint animation) when the ball passes through. * **Obstacles:** Bombs (black spheres with fuses) that explode on contact, creating a "Game Over." * **Visual Effects:** * **Motion Trails:** When the ball moves fast, add a "speed line" trail effect (orange/yellow ribbons) behind it. * **Impact:** Small dust particles or "poof" effects when the ball hits a drawn line. * **Confetti:** A burst of colorful particles when a level is completed (basket made). * **Optimization:** Keep polygon counts low for mobile performance. Use simple geometry for lines to ensure smooth drawing at 60fps on mobile devices. ### 2. Audio Requirements * **BGM (Background Music):** A lo-fi, chill hip-hop beat or an upbeat, funky jazz loop. It should be rhythmic but not distracting, encouraging focus. * **Sound Effects (SFX):** * **Drawing:** A satisfying "scribble" or "scratch" sound that loops while the player is drawing a line. * **Bounce:** A "boing" or stylized rubber ball sound when the basketball hits a drawn line. * **Swoosh:** A clean "swish" sound when the ball goes through the hoop without touching the rim. * **Win:** A short, triumphant trumpet or whistle sound for level completion. * **Explosion:** A cartoony "boom" if the ball hits a bomb. ### 3. Gameplay Loop * **Core Mechanic:** The basketball spawns at the top of the screen and falls due to gravity. The player must draw lines on the screen *before* or *during* the fall to guide the ball into the hoop. * **Physics:** * The ball should have bouncy physics (high restitution). * The drawn lines act as static rigid bodies that deflect the ball. * Gravity should be realistic but slightly forgiving. * **Victory Condition:** The ball successfully passes through the hoop (trigger zone detection). * **Failure Condition:** The ball falls off the screen (bottom boundary) or hits a bomb obstacle. * **Progression:** Start with simple "drop the ball into the bucket" layouts. Gradually introduce multiple balls (must score all 3 to win), moving hoops, and bomb obstacles that must be shielded against. * **Ink Limit:** Implement a "Pencil Lead" bar (UI) that decreases as lines are drawn. If the bar empties, the player cannot draw anymore lines. ### 4. Mobile Controls & Interaction * **Screen Orientation:** **Portrait Mode (Vertical)** is mandatory for one-handed play. * **Touch Controls:** * **Draw:** Single-finger drag on the screen creates the blue line collider. The line follows the exact path of the finger. * **Input Smoothing:** Apply Catmull-Rom splines or similar smoothing to the touch input so drawn lines don't look jagged or pixelated. * **Line Limit:** Allow a maximum of 3 separate lines on screen at once, or a total length limit. * **UI Layout:** * **Top Center:** Current Level Indicator. * **Top Right:** "Retry" button (icon style, 44x44px touch area). * **Top Left:** "Ink/Lead" Gauge (progress bar). * **Feedback:** * **Haptic Feedback:** Trigger a very light vibration (using `navigator.vibrate`) whilst drawing to simulate friction. * **Physics Feedback:** When the ball hits a line, the line should subtly flash white or vibrate visually to show impact. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
