如何控制數組中的所有游戲對象？

Question

我有一個生成器，每次按 (1) 時都會生成一個球，每個球都將存儲在名為“ targetBall ”的游戲對象數組中，我有一個AI 播放器，它使用Move()方法排斥球，但問題是AI 玩家只看到數組中的第一個球，即球 [0]，如代碼所示，如​​何讓 AI 玩家看到所有生成的球（無限球），我嘗試使用 for 循環，但我沒有成功（注意：每件事都很完美）

void Move()
    {
        targetBall = GameObject.FindGameObjectsWithTag("HokeyBall");

            if (targetBall[0].GetComponent<HokyBall>().ballDirection == Vector3.right)
            {
                ballPos = targetBall[0].transform.localPosition;

                if (transform.localPosition.x < Lboundry && ballPos.x > transform.localPosition.x)
                {
                    transform.localPosition += new Vector3(speed * Time.deltaTime, 0, 0);
                }
                if (transform.localPosition.x < Lboundry && ballPos.x < transform.localPosition.x)
                {
                    transform.localPosition += new Vector3(-speed * Time.deltaTime, 0, 0);
                }
            }
}

這是我嘗試找到使用 for 循環生成的每個球，並給我錯誤（無法將“int”轉換為“GameObject”）

void Move()
        {
            targetBall = GameObject.FindGameObjectsWithTag("HokeyBall");

foreach (GameObject i in targetball)
{
    
                if (targetBall[i].GetComponent<HokyBall>().ballDirection == Vector3.right)
                {
                    ballPos = targetBall[i].transform.localPosition;
    
                    if (transform.localPosition.x < Lboundry && ballPos.x > transform.localPosition.x)
                    {
                        transform.localPosition += new Vector3(speed * Time.deltaTime, 0, 0);
                    }
                    if (transform.localPosition.x < Lboundry && ballPos.x < transform.localPosition.x)
                    {
                        transform.localPosition += new Vector3(-speed * Time.deltaTime, 0, 0);
}
                    }
                }
    }

foreach從集合中返回對象，因此您無權訪問該集合。

Foreach方式 -

    void Move()
    {
        targetBall = GameObject.FindGameObjectsWithTag("HokeyBall");
        foreach (GameObject go in targetball)
        {
            if (go.GetComponent<HokyBall>().ballDirection == Vector3.right)
            {
                ballPos = go.transform.localPosition;
                if (transform.localPosition.x < Lboundry && ballPos.x > transform.localPosition.x)
                {
                    transform.localPosition += new Vector3(speed * Time.deltaTime, 0, 0);
                }

                if (transform.localPosition.x < Lboundry && ballPos.x < transform.localPosition.x)
                {
                    transform.localPosition += new Vector3(-speed * Time.deltaTime, 0, 0);
                }
            }
        }
    }

For循環——

    void Move()
    {
        targetBall = GameObject.FindGameObjectsWithTag("HokeyBall");
        for (int i = 0; i < targetBall.Length; i++)
        {
            if (targetBall[i].GetComponent<HokyBall>().ballDirection == Vector3.right)
            {
                ballPos = targetBall[i].transform.localPosition;
                if (transform.localPosition.x < Lboundry && ballPos.x > transform.localPosition.x)
                {
                    transform.localPosition += new Vector3(speed * Time.deltaTime, 0, 0);
                }

                if (transform.localPosition.x < Lboundry && ballPos.x < transform.localPosition.x)
                {
                    transform.localPosition += new Vector3(-speed * Time.deltaTime, 0, 0);
                }
            }
        }
    }
