為什么 GameObject2 向 GameObject1 的原始位置而不是當前位置移動？

Question

我目前有一個游戲對象（一個敵人）應該向另一個游戲對象（玩家）移動，而是向玩家的原始位置 (0, 0) 移動。 我已經遇到了敵人遠離玩家而不是向他們移動的問題，我通過在 Vector2 前面添加一個 - 符號來解決這個問題。 附加到兩個對象的腳本如下。 我知道兩者在其他方面都沒有得到優化，但現在我只關心搞砸的運動。

游戲對象 1（玩家）：

        move.x = horizontal;
        move.y = vertical;

        if (Input.GetKeyDown("e") && canAtk) 
        {

            StartCoroutine(startAtk());
        }
    }

        if (move.x > 0.01f)

        {
            horizontal *= diaFactor;
            vertical *= diaFactor;
        }
        body.velocity = new Vector2(horizontal * runSpeed, vertical * runSpeed);

    }

                body.velocity = -Vector2.MoveTowards(selfTrans.position, new Vector2(plrG.x, plrG.y), step);
                if (isWithin(1f) && playerController.atkOn) 
                {

    bool isWithin(float dist)
    {
        float rDist = Vector2.Distance(selfTrans.position, g.transform.position);
        return rDist < dist;
    }
}```

Answer 1

這是問題

body.velocity = -Vector2.MoveTowards(selfTrans.position, new Vector2(plrG.x, plrG.y), step);|

您正在將某個位置設置為您的速度。 嘗試從類似的東西開始：

body.velocity = (plrG - selfTrans.position).normalized * step;
