private float vertical;
//移动向量
Vector3 movement;
//用四元数表示旋转
//初始化表示不旋转
Quaternion Rotation = Quaternion.identity;
//旋转速递
public float turnSpeed = 20.0f;
// Start is called before the first frame update
void Start()
{
player = GetComponent<Rigidbody>();
animator = GetComponent<Animator>();
}
// Update is called once per frame
void Update()
{
//水平轴
horizontal = Input.GetAxis("Horizontal");
//垂直轴
vertical = Input.GetAxis("Vertical");
}
private void FixedUpdate()
{
//初始化移动向量
movement.Set(horizontal, 0, vertical);
movement.Normalize();
//判断是否有横向移动/纵向移动
bool hasHorizontal = !Mathf.Approximately(horizontal, 0.0f);
bool hasVertical = !Mathf.Approximately(vertical, 0.0f);
//判断是否在移动
bool isRunning = hasHorizontal || hasVertical;
animator.SetBool("isRun", isRunning);
//用三维矢量来表示转向后玩家的方向
Vector3 desiredForward = Vector3.RotateTowards(transform.forward,movement,turnSpeed * Time.deltaTime,0f);
Rotation = Quaternion.LookRotation(desiredForward);
}
private void OnAnimatorMove()
{
//使用用户输入的三维矢量作为移动方向，使用动画中每次0.02秒移动距离作为距离
player.MovePosition(player.position + movement * 0.05f);
player.MoveRotation(Rotation);
}
}
