How to control all GameObjects in array?-CodePudding

I have a generator which generate a ball every time I press (1) , each ball will be stored in Array of Gameobjects called "targetBall" , I have an AI player which repels the ball with Move() method, but the problem is the AI player see only the first ball in array which is ball [0] as shown in code , how I can make the AI player see all the generated ball (infinite balls) , I tried to use for loop but I didn't make it (note : every thing worked perfect)

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);
                }
            }
}

and this is my attempt to find each ball generated using for loop , and give me error (cant convert "int" to "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);
}
                    }
                }
    }

CodePudding user response：

foreach returns object from the collection, so you don't have access to that collection.

Foreach way -

    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 loop -

    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);
                }
            }
        }
    }
