Hi Im trying to make an Instance of a prefab and the edit some components in the children but i can’t seam to be able to use the GetComponent function. This is the code where the error happens:

    public void Create()
    {
        for(int A = 0; A != Druk_A_C.Length; A++)
        {
            GameObject Temp = Instantiate(Template_List, Container.transform);
            Temp.transform.Find("Name").gameObject.GetComponent<Text>().text = Druk_A_C[A].GetName();
        }
    }

And there is all the code if you need:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System;
using UnityEngine.UI;

public class Master : MonoBehaviour {

    
    public TextAsset Drunk;
    private A_C[] Druk_A_C;
    private string[] Drinks;
    private string[] split;
    public GameObject Template_List;
    public GameObject Container;

    void Awake()
    {
        string temp_druk = Drunk.text;
        Drinks = temp_druk.Split('

');
Drinks[0] = “”;
split = null;
Druk_A_C = new A_C[Drinks.Length];
Load_1();
Create();
}

    //loading
    public void Load_1()
    {
        List<string> Splitter = new List<string>();
        for (int iso = 1; iso < Drinks.Length; iso++)
        {
            Splitter = new List<string>();
            string[] Temp = this.Drinks[iso].Split(' ');
            for (int num = 0; num < Temp.Length; num++)
            {
                Splitter.Add(Temp[num]);
            }
            split = Splitter.ToArray();
            Druk_A_C[iso] = new A_C();
            Druk_A_C[iso].SetName(split[0]);
            Druk_A_C[iso].SetIGD(split[1]);
            Druk_A_C[iso].SetType(split[2]);
            Druk_A_C[iso].SetText(split[3]);
        }
    }

    public void Create()
    {
        for(int A = 0; A != Druk_A_C.Length; A++)
        {
            GameObject Temp = Instantiate(Template_List, Container.transform);
            Temp.transform.Find("Name").gameObject.GetComponent<Text>().text = Druk_A_C[A].GetName();
        }
    }

}

class A_C
{    
    private string Name;
    private string IGD;
    private string Type;
    private string Text;

    public A_C()
    {

    }
    public void SetName(string name)
    {
        name = name.Replace('_', ' ');
        name = name.Replace('*', '

‘);
this.Name = name;
}
public string GetName()
{
return Name;
}
public void SetIGD(string IGD)
{
IGD = IGD.Replace(’‘, ’ ‘);
IGD = IGD.Replace(’*’, ’
‘);
this.IGD = IGD;
}
public string GetIGD()
{
return IGD;
}
public void SetType(string type)
{
this.Type = type;
}
public string Gettype()
{
return Type;
}
public void SetText(string Text)
{
Text = Text.Replace(’‘, ’ ‘);
Text = Text.Replace(’*’, ’
');
this.Text = Text;
}
public string GetText()
{
return Text;
}
}

There are a number of things that could be going wrong:

Temp.transform.Find("Name").gameObject.GetComponent<Text>().text = Druk_A_C[A].GetName();

Temp could be null if Instantiate is returning null (which would happen if Template_List is null because its not assigned in the objects properties window).

Temp.transform.Find(“Name”) might be null if it can’t find a game object called “Name”.

Temp.transform.Find(“Name”).gameObject.GetComponent() could be null if the gameobject “Name” doesn’t have a text component.

I would break this down into separate statements to see which part is failing, check if one to see if its null and print out a debug message if it is.

I’ve fixed it. Thanks for the help :smiley:
