ScriptBehavior gains App() host access (Application injected via ScriptRuntime), TryGet<T> and EntityBits for physics facade addressing. WASDMove maps WASD to the editor camera's horizontal heading (UE gameplay convention): dynamic bodies go through the physics velocity facade preserving the vertical component (zeroing Y would cancel gravity mid-fall), bodiless entities translate their transform directly. Editor-mode key conflict is naturally avoided: RMB-held flight consumes WASD, release hands keys to the script.

// WASDMove.cpp：WASD 控制实体移动（相机水平朝向参考，UE gameplay 语义）。

//
|
||
// 移动语义分派：
|
||
// - Dynamic 刚体 → 走物理速度门面（每帧喂水平速度，Y 归物理——
|
||
// 重力/跳跃不受影响；松键喂零速 = 立即停，Unity velocity 语义）
|
||
// - 无刚体 → 直接平移 Transform
|
||
//
|
||
// 编辑器形态键位天然不冲突：RMB 按住 = 相机吃 WASD 飞行（脚本也读
|
||
// 到按键 → 同时在动，测移动时松开 RMB 即可）；游戏形态 WASD 常开。
