中文译文
我希望你担任一名顶尖的图形与交互工程师。请设计一个3D物理积木堆叠游戏引擎，用于教授基本句型结构（主语-谓语-宾语）。
游戏名称：《句法堆叠：动态语法》。
游戏功能：一个物理平衡平台悬浮在3D空间中央。用户会获得一系列彩色矩形积木，代表不同的词性。点击屏幕会从设定高度将一块积木投放到平台上。核心机制依赖于精确的刚体物理：积木具有不同的质量和摩擦系数，迫使它们在结构上保持平衡。如果堆叠顺序遵守语法重量规则，平台保持稳定；如果结构平衡不当，平台会根据质心计算动态倾斜，导致一场壮观的物理驱动坍塌。
设计风格：包豪斯几何美学。使用干净的柔和色块、模拟光滑木质玩具质感的哑光PBR材质，以及柔和的体积阴影来强调空间深度。
所用技术：使用Three.js进行视觉渲染，使用Ammo.js进行高精度的质量与重心物理计算，并使用OrbitControls实现360度视角旋转。
English original
I want you to act as a Top-Tier Graphics and Interaction Engineer. Please design a 3D physical block stacking game engine to teach basic sentence structures (Subject-Verb-Object).
Game Name: 《Syntactic Stack: Kinetic Grammar》.
Game Function: A physical balancing platform floats in the center of a 3D space. The user is provided with a sequence of colored rectangular blocks representing different parts of speech. Clicking the screen drops a block from a set height onto the platform. The core mechanics rely on precise rigid-body physics: the blocks have differing masses and friction values, forcing them to balance structurally. If the stacking sequence obeys grammatical weight rules, the platform stays stable; if the structure balances improperly, it tilts dynamically based on center-of-mass calculations, leading to a spectacular physics-driven collapse.
Design Style: Bauhaus geometric aesthetic. Utilize clean pastel color blocks, matte PBR materials simulating smooth wooden toy textures, and soft volumetric shadows to emphasize spatial depth.
Technologies Used: Three.js for visual rendering, Ammo.js for high-precision mass and center-of-gravity physics computations, and OrbitControls for 360-degree viewing angle rotation.
