这里的主要内容就是下述代码；
// 获取左手控制器的旋转（四元数表示）Quaternion aRotationQuaternion = leftHandController.rotation;// 计算旋转差值（四元数表示）Quaternion rotationDifference = Quaternion.Euler(0, -90, -90);// 应用差值到左手控制器的旋转并获取新的四元数Quaternion bRotationQuaternion = aRotationQuaternion * rotationDifference;// 将新的四元数设置给左手的旋转leftHand.rotation = bRotationQuaternion;
下面是全部代码、加入Animation 的ik控制器和手部动画控制就可以实现手柄控制手臂手部位置移动、手部旋转和手指的操作了
