Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "**Royal Card Clash**". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style:** Modern Retro Pixel Art. Use `THREE.PlaneGeometry` with pixel-art textures for all game elements to simulate a 2D look within a 3D space. * **Camera:** Orthographic camera, top-down view, locked to fit the board width. * **Background:** A scrolling or subtle pulsating shader background in "Royal Blue" (#2c6ec9) with a faint diamond checkerboard pattern, mimicking the provided screenshot. * **Card Assets:** * **Player Cards:** Standard playing cards (Numbers 2-10, Aces) rendered as pixel art. * **Royal Cards (Enemies):** Jacks, Queens, and Kings with distinct pixel art portraits. They should look menacing/armored. * **Visual Effects:** When a Royal is damaged, flash the sprite white. When defeated, play a "Slash" animation (a glowing white line cutting across the card) followed by a particle explosion (using `THREE.Points` for performance). * **Mobile Optimization:** Use a single texture atlas for all card sprites to reduce draw calls. Disable shadows and complex lighting; use unlit materials (`MeshBasicMaterial`). ### 2. Audio Requirements * **BGM:** An energetic, looping **Chiptune / 8-bit** track. It should feel heroic and fast-paced (120 BPM). * **Sound Effects (SFX):** * **Card Flip/Draw:** A crisp paper "snap" sound. * **Attack (Damage):** An 8-bit "crunch" or dull hit sound. * **Royal Defeated:** A high-pitched retro "coin" or "power-up" sound combined with a sword slash noise. * **Invalid Move:** A low-pitched buzzer. * **Victory:** A short 8-bit fanfare. ### 3. Gameplay Loop * **Board Setup:** The board consists of **3 vertical lanes**. * **Top Zone:** Where Royal Cards spawn and advance downwards. * **Bottom Zone:** The Player's hand (holds up to 3 cards active at a time). * **Turn Logic:** * Royals spawn with HP based on rank (e.g., J=11, Q=12, K=13). * The player drags a card from their hand to one of the 3 lanes. * **Combat Rules:** * **Damage:** Playing a numbered card deals damage equal to its value to the Royal in that lane (regardless of suit). * **Lethal Blow:** To reduce a Royal's HP to 0 and remove it from the board, the playing card **MUST match the suit** of the Royal. If the suit does not match, the Royal stays at 1 HP. * **Win/Loss Conditions:** * **Win:** Successfully clear the entire deck of Royals. * **Loss:** The player runs out of usable cards in the deck before clearing the Royals, or a Royal reaches the bottom of the lane (Game Over). ### 4. Mobile Controls & Interaction * **Orientation:** **Portrait Mode** (Vertical). The 3 lanes should be columns side-by-side. * **Touch Controls:** * **Drag & Drop:** Implement Raycasting for touch input. Users press and hold a card from the bottom hand, drag it visually to a lane, and release to play. * **Snap-to-Grid:** When dragging near a lane, the card should visually "snap" or highlight the target lane before releasing. * **UI Layout:** * Score/Deck Count display at the very top (safe from notch). * Card interaction area at the bottom 25% of the screen (easy thumb reach). * No small buttons; all interactable elements must be at least 44x44 pixels. * **Feedback:** * **Haptic:** Trigger a short vibration (`navigator.vibrate(50)`) when a card is successfully played or a Royal is killed. * **Visual:** Screen shake (camera jitter) on heavy hits (King kills). Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
