设计 3D 词汇分类游戏原型：拖动漂浮水晶到对应类别区域，正确吸附、错误弹回。
我要你充当一名精通沉浸式教育机制的主游戏设计师。请为一节英语词汇课设计一个三维语义分类游戏原型。 游戏名称：《Semantic Pull: Word Family Grid》。 游戏功能：视口内显示三个独立发光的三维概念区域（例如，代表“动物”“水果”“颜色”等类别的立方体、圆柱体和环面）。多个漂浮的水晶节点在屏幕周围随机漂移，漂移算法采用低频噪声函数。用户可用鼠标指针拖动任意水晶节点；释放后，系统将计算该节点与最近区域之间的距离及磁性吸引力向量。若水晶节点与正确类别区域对齐，则通过平滑的 LERP 缩放动画被区域吸收，并触发光迹爆发特效。若分类错误，则弹性排斥向量会将其迅速弹回原始位置。 设计风格：专为儿童定制的复古未来主义赛博朋克风格。深色背景与类别区域高度自发光、半透明的霓虹材质形成强烈对比，水晶内部具有全息视差效果。 使用技术：Three.js 用于资源管理与着色器，GSAP 实现非线性磁力弹簧与吸引力插值，Raycaster 实现高精度的三维包围盒交互。
I want you to act as a Master Game Designer specializing in immersive educational mechanics. Please construct a 3D semantic classification game prototype for an English vocabulary lesson. Game Name: 《Semantic Pull: Word Family Grid》. Game Function: The viewport displays three distinct glowing 3D conceptual zones (e.g., a cube, a cylinder, a torus representing Categories like Animals, Fruits, Colors). Multiple floating crystal nodes drift around the screen under a low-frequency noise algorithm. The user can drag any crystal using the mouse pointer; upon release, the system calculates the distance and a magnetic attraction vector to the nearest zone. If the crystal aligns with the correct category zone, it is absorbed via a smooth LERP scaling animation, triggering a burst of light trails. If incorrect, a elastic repulsion vector snaps it back to its origin. Design Style: Retro-futuristic cyberpunk tailored for kids. Dark background contrasting with highly emissive, translucent neon materials for the category zones and holographic視差 effects inside the crystals. Technologies Used: Three.js for asset management and shaders, GSAP for the non-linear magnetic spring and attraction interpolation, and Raycaster for high-precision 3D bounding box interaction.
