How delete clone GameObjects in Unity-CodePudding

So I didn't find something useful, to solve my problem. My script is downloading an JSON Array from my Server and fills some text with that informations. Thats the part of code:

 void DrawUI()
{
    GameObject buttonObj = transform.GetChild (0).gameObject; //Gets button to clone it

    GameObject g;

    int N = allCars.Length;

    for (int i = 0; i < N; i  )
    {
        g = Instantiate(buttonObj, transform);

        g.transform.Find("name").GetComponent<Text>().text = allCars[i].carName;
        g.transform.Find("type").GetComponent<Text>().text = allCars[i].type;
        g.transform.Find("price").GetComponent<Text>().text = allCars[i].price  "€";
        

        
        if(balance < int.Parse(allCars[i].price))
        {
            g.transform.Find("price").GetComponent<Text>().color = Color.red;
        } else if (balance >= int.Parse(allCars[i].price))
        {
            g.transform.Find("price").GetComponent<Text>().color = new Color32(53, 140, 3, 255);
        }

        g.GetComponent<Button>().AddEventListener(i, OpenBuyDialog);
        itemIndex = i;

    }

    Destroy(prefab);
}

This code loops and creates clones of my buttons, all fine. When user confirms the Buy Dialog, it should reload/refresh the list, but for that I have to delete the old clones. I can't find how to do that properly.

CodePudding user response：

Assume the transform has only one child (buttonObj) at the beginning, then you can delete the clones with this code.

var count = transform.childCount;
for (var i = 1; i != count;   i)
    Destroy(transform.GetChild(i).gameObject);

CodePudding user response：

Add your instantiates objects to a member:

private List<GameObject> buttons;

On refresh, iterate through buttons and call Destroy on each GameObject.
