c# - C# UNITY 2D 试图在 x 方向翻转精灵

问题描述

我要做的就是当敌人转身时，它的精灵会翻转，下面的代码是我所管理的，但现在它只在两次接近但不是我需要的方向改变后翻转。请帮忙。

   [HideInInspector]
    public bool facingRight = true;
    public float speed;
    Rigidbody2D rbody;
    public float timer;
    Animator anim;
    public float directionx;

// Use this for initialization

void Start()
    {
        rbody = GetComponent<Rigidbody2D>();

        StartCoroutine(Move(timer));
    }



    IEnumerator Move(float timer)
    {
        while (0 < 1)

        {
            Vector2 targetVelocity = new Vector2(directionx, 0);

            rbody.velocity = targetVelocity * speed;

            yield return new WaitForSeconds(timer);

            facingRight = !facingRight;

            Vector3 theScale = transform.localScale;

            theScale.x *= -1;

            transform.localScale = theScale;

            Vector2 targetVelocity1 = new Vector2(-directionx, 0);

            rbody.velocity = targetVelocity1 * speed;

            yield return new WaitForSeconds(timer);
        }

    }

}

解决方案

该代码非常不言自明，您只需要设置一个变量即可知道玩家开始移动的方向（m_FacingRight在我的情况下），然后决定何时发生“翻转”调用flipFunction()：

private bool m_FacingRight = true;  // For determining which way the player is currently facing.  

private void flipFunction()
{
  // Switch the way the player is labelled as facing.
  m_FacingRight = !m_FacingRight;

  // Multiply the player's x local scale by -1.
  Vector3 theScale = transform.localScale;
  theScale.x *= -1;
  transform.localScale = theScale;    
}
