为什么我的Unity C＃子弹毫不及格地保持稳定的速度？

Question

敌人的子弹在敌人射击并开始旋转后弯曲（朝着躲避的球员）。所有内容都是实例化的，并且在Update（）中调用了攻击，但是CopyofCurrentRotation（我知道在我的代码中拼写错误）仍在更改子弹的速度。

public IEnumerator Attack(string goname)
    {
        IsAttacking = true; //Indicates if we are attacking
        oldmovementspeed = MovementSpd;
        MovementSpd = 0;

        GameObject p = GuitarShooter.GrabObject();
        p.transform.position = exitPoints[0].position;
        p.transform.SetParent(this.transform);
        yield return new WaitForSeconds(2.00f); 
        EvilProjectile q = p.GetComponent<EvilProjectile>();
         q.Initialize(q.MyDamage);

        if (q != null && q.HasBeenFired != true )
        {   
    
            currentRoration = transform.rotation * Vector3.up;
            copyofcurrentRoration = new Vector3(currentRoration.x, currentRoration.y, currentRoration.z);
            q.MyEvilBody.velocity =  CopyOfCurrentRoration * q.MySpeed;
            q.HasBeenFired = true;
           
   
        IsAttacking = false;
    
        MovementSpd = oldmovementspeed;
        StartCoroutine(Reload("morebullets"));
    }

Answer 1

以下行引起了问题：

p.transform.SetParent(this.transform);

传递null而不是this.transform解决了问题

p.transform.SetParent(null);
