一、核心规则（旋转顺序重点）
蓝图面板显示顺序：Roll(X) → Pitch(Y) → Yaw(Z)
C++ FRotator 构造顺序：FRotator(Pitch, Yaw, Roll)
转换公式：
C++旋转值 = FRotator(蓝图中间值, 蓝图最右值, 蓝图最左值)
二、当前蓝图原始参数
弹簧臂 Rotation：Roll=-90，Pitch=-90，Yaw=0
非默认勾选项：
关闭碰撞检测 Do Collision Test = false
开启相机延迟 Enable Camera Lag = true
延迟速度 Camera Lag Speed = 2.0
相机非默认项：
投影模式：正交 Orthographic
正交宽度：2000
近 / 远裁剪面、其余选项均为引擎默认，无需代码设置
