Prompt

MODEL: Seele01-Flash
Please use Three.js to generate a **mobile-first game** with the theme "Unlock Block - 3D Sliding Puzzle". Please read the following detailed game design requirements first, and then generate the code accordingly: ### 1. Assets & Environment * **Visual Style**: Modern, clean, and minimalist 3D aesthetic. Use `THREE.RoundedBoxGeometry` (or extruded shapes with bevels) for blocks to give them a tactile, "toy-like" feel. * **Color Palette**: * **Hero Block**: Vibrant Cyan/Blue (glossy material). * **Villain Blocks**: Hot Pink/Magenta (matte material). * **Game Board**: A deep slate grey or dark charcoal container with a sunken 6x6 grid floor. * **Exit Zone**: A highlighted area or glowing opening on the right side of the board wall indicating the goal. * **Lighting**: Use a Soft setup with `AmbientLight` and a `DirectionalLight` casting soft shadows to emphasize the height and depth of the blocks. * **Camera**: Fixed high-angle Orthographic Camera (`THREE.OrthographicCamera`) to ensure the puzzle grid remains perfectly square and readable on all screen sizes without perspective distortion. * **Performance**: Use instanced mesh if possible for the floor grid, but since the block count is low (<20), standard Mesh is acceptable. Ensure textures (if any) are compressed. ### 2. Audio Requirements * **BGM**: A "Zen/Thinking" style track. Lo-fi beats or ambient electronic music that is repetitive but non-intrusive to aid concentration. * **Sound Effects (SFX)**: * **Selection**: A subtle "pop" or "click" when a user touches a block. * **Sliding**: A smooth friction sound (like plastic on plastic) that plays while dragging. * **Collision**: A soft "thud" when a block hits another block or the wall. * **Victory**: A bright, ascending chime or fanfare when the Blue Block exits the grid. ### 3. Gameplay Loop * **Level Logic**: The game takes place on a 6x6 grid. * **Goal**: Move the Blue Block (1x2 size, horizontal) through the exit on the right edge of the grid. * **Obstacles**: Pink Blocks of varying sizes (1x2 or 1x3). * **Constraints**: * **Orientation Lock**: Horizontal blocks can *only* move Left/Right. Vertical blocks can *only* move Up/Down. * **Collision**: Blocks cannot pass through each other or the grid boundaries. * **Win Condition**: When the Blue Block's position coordinates overlap with the Exit Zone coordinates, trigger the "Level Clear" state. * **Progression**: Upon winning, display a "Success" UI overlay and automatically load the next block configuration (simulate level data using a JSON array). ### 4. Mobile Controls & Interaction * **Touch Input System**: Use `PointerEvents` (pointerdown, pointermove, pointerup) mapped to a `THREE.Raycaster` for universal support (Mouse + Touch). * **Drag Mechanics**: * Implement 1:1 finger tracking. * **Axis Locking**: As soon as a drag starts, calculate the vector. If the block is Horizontal, ignore Y-axis delta. If Vertical, ignore X-axis delta. * **Snap-to-Grid**: When the player releases a block, it should visually tween (animate) to the nearest valid grid integer position. * **Screen Adaptation**: * Support **Portrait Mode** as the primary orientation. * Ensure the camera zoom adjusts dynamically based on `window.innerWidth` so the 6x6 board always fits within the screen width with a small margin. * **Feedback**: * **Visual**: Highlight the selected block (emissive material intensity increase) while dragging. * **Haptic**: Trigger `navigator.vibrate(10)` when a block hits a wall or snaps into place (if supported). * **UI Layout**: * Place a "Reset Level" button and "Level Counter" at the top of the screen (outside the 3D canvas area or as an HTML overlay). * Buttons must have a minimum touch target size of 44x44px. Do not ask for clarification. Do not request confirmation. Directly execute the generation task based on the given instructions.
