小时候给向上移动的主相机制作了雨粒子效果,但雨效果并不完美,因为它向北移动

Made a rain particle effect as a child to main camera which moves upwards but the rain effect is not perfect since its moving north

我在 unity 2d 中制作了一个雨粒子系统,并将其作为子项连接到主相机,以便它可以与相机一起向北移动。但是下雨效果并不完美,因为一些颗粒在向上摆动。我已将脚本附加到下面给出的相机。有没有其他方法可以解决这个问题。

public float  translation ;
public float highspeed;//highest speed of the camera
public float incfactor;//increasing ,multiplying number
float timer=0f ;
 public bool ismoving = false;


Rigidbody2D dia;

void Start()
{

    dia = GetComponent<Rigidbody2D> ();
}


void  Update()
{

    if (Input.GetMouseButtonDown(0)) {
        RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), Vector2.zero);
        if(hit.collider != null) {

            if (hit.collider.tag =="dialogue") {
                FindObjectOfType<audioManager> ().Play ("levelbeginclick");
                Destroy (hit.collider.gameObject);
                ismoving = true;
            }
            }
        }

    if (ismoving == true) {
        Updatemove ();
    }
    }





 public void Updatemove ()
{

    timer += Time.deltaTime;



    if (timer > 1f&& translation<highspeed) { 
            timer = 0; // reset timer
        translation +=incfactor ; 
        }

    transform.Translate (0, translation*Time.deltaTime, 0);




}

public void stopmoving()
{
    ismoving = false;
}

}

所以按照@ARutherford 所说将模拟 Space 更改为世界应该可以解决问题
