Unity 2D游戏杆运动

Question

**嗨，我正在尝试进行一些操纵杆移动，当角色离开时，角色精灵将“面孔”向左翻转。实际上看起来像在工作，但事实并非如此。字符越过红线的左侧时，它将向左旋转；当字符移动到右侧时，它将向右旋转。那么我该如何解决呢？ ** 我的代码；

float horizontal;
public float Speed;

public Joystick joystick;
Rigidbody2D rb;
bool facingRight = true;
private void Start()
{
    rb = GetComponent<Rigidbody2D>();
}
private void FixedUpdate()
{
    
    horizontal = joystick.Horizontal;
    if (horizontal != 0)
    {
        //transform.up = new Vector3(horizontal * Speed, 0, 0);
        transform.Translate(new Vector3(horizontal, 0, 0)*Speed * Time.deltaTime);
        

    }
    if (gameObject.GetComponent<Rigidbody2D>().transform.position.x < 0 && facingRight)  
    {
        flipFace();
    }
    else if (gameObject.GetComponent<Rigidbody2D>().transform.position.x > 0 && !facingRight)
    {
        flipFace();
    }

}

void flipFace()
{
    facingRight = !facingRight; 
    Vector3 tempLocalScale = transform.localScale;
    tempLocalScale.x *= -1; 
    transform.localScale = tempLocalScale; 
}

Answer 1

您应该检查自己的动向或输入，而不是检查transform.position.x。当速度> 0或<0时，您可以翻转面部，这意味着您实际上是在向左还是向右走。检查速度而不是位置。

Answer 2

它不起作用，因为我没有使用速度。刚体中没有速度，因此我更改了代码，如下所示：

if (horizontal != 0)
        {
            //transform.up = new Vector3(horizontal * Speed, 0, 0);
            //transform.Translate(new Vector3(horizontal, 0, 0)*Speed * Time.deltaTime);
            rb.velocity = new Vector3(horizontal * Speed, rb.velocity.y);


        }
        else
        {
            rb.velocity = new Vector3(0, 0, 0);
        }
        if (rb.velocity.x < 0 && facingRight) // < 0 ise sola gidiyor demektir  > 0 is sağa gidiyor demektir
        {
            flipFace();
        }
        else if (rb.velocity.x > 0 && !facingRight)
        {
            flipFace();
        }
