c# - Rigidbody2D 在撞到对撞机时停止

Question

我有一个带有 Rigidbody2D 和圆形碰撞器的播放器。玩家收集带有圆形对撞机的硬币。我左右移动播放器。当它收集硬币时，硬币会被破坏，玩家会停止，所以我必须再次触摸才能继续向左/向右移动。那么，如何在不停止玩家的情况下收集硬币呢？这是我移动刚体的代码:

void TouchMove()
{
    if (Input.touchCount > 0)
    {
        Touch touch = Input.GetTouch(0);
        float middle = Screen.width / 2;

        if (touch.position.x < middle && touch.phase == TouchPhase.Began)
        {
            MoveLeft();
        }

        else if (touch.position.x > middle && touch.phase == TouchPhase.Began)
        {
            MoveRight();
        }
    }
    else
    {
        SetVelocityZero();
    }
}

public void MoveLeft()
{
    rb.velocity = new Vector2(-playerSpeed, 0);
}

public void MoveRight()
{
    rb.velocity = new Vector2(playerSpeed, 0);
}

public void SetVelocityZero()
{
    rb.velocity = Vector2.zero;
}

您的硬币不应与任何物体碰撞，尤其是玩家。

让硬币的碰撞器被触发，然后使用 OnTriggerEnter2D 来检测它何时接触到玩家以销毁硬币而不是 OnCollisionEnter2D。

附加到你的硬币游戏对象:

void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.gameObject.CompareTag("Player"))
    {
        Debug.Log("Player detected. Destroying this coin");
        Destroy(gameObject);
    }
}

或者附加到你的玩家游戏对象:

void OnTriggerEnter2D(Collider2D collision)
{
    if (collision.gameObject.CompareTag("Coin"))
    {
        Debug.Log("Coin detected. Destroying coin");
        Destroy(collision.gameObject);
    }
}
