小白求帮助，角色实现不了转身。

void Turning()
{
Ray camRay = Camera.main.ScreenPointToRay(Input.mousePosition);
RaycastHit floorHit;
if (Physics.Raycast(camRay, out floorHit, camRayLength, floorMask))
{
Vector3 playerToMouse = floorHit.point - transform.position;
playerToMouse.y = 0f;
Quaternion newRotation = Quaternion.LookRotation(playerToMouse);
playerRigidbody.MoveRotation(newRotation);
}
}
根据官方的幽灵射手视频写的，角色能移动，但不会转身，百度也百度不到，求吧里大神帮助一下，困我好几天了。
