InputField removing itself when i click play

i assigned my inputfield on inspector but when i start game its removing itself and i have to put it manually on game.

and i use this code but its didnt working.

Code (CSharp):

1. inputMiktar = GameObject.Find("InputFieldFiyatGir").GetComponent<InputField>();

how i solve this problem help me

This is a general scripting question - so why are you asking this in 2D forum?

"InputField removing itself when i click play"

You are trying to find your GameObject, and you actually don't find it, and you end up assigning a null value to your variable. You didn't either say, if you actually get some errors in your console.

Without complete code it is hard to say what happens. Maybe edit your post and add full code here.

But in general, make sure you have a GameObject named exactly "InputFieldFiyatGir" and make sure it really does have a InputField component. It is usually best to split your code a bit if you are unsure if something exists. That way you can get proper easy to read errors when you run your code:

Code (CSharp):

1. public class Testing : MonoBehaviour
2. {
3.     [SerializeField] private GameObject obj;
4.     [SerializeField] private BoxCollider col;
5.  
6.     void Start()
7.     {
8.         obj = GameObject.Find("Cube");
9.         Debug.Log("obj:" + obj.name);
10.  
11.         col = obj.GetComponent<BoxCollider>();
12.         Debug.Log("col:" + col.ToString());
13.     }
14. }

If I were you, I would read some threads in general scripting. You can find this kind of questions on daily basis there, and you'll find several good answers too!

 

sorry im new on forum

Code (CSharp):

1. private GameObject obj;
2.     private InputField inputMiktar;
3.     // Start is called before the first frame update
4.     void Start()
5.     {
6.        
7.             obj = GameObject.Find("InputFieldFiyatGir");
8.             Debug.Log("obj:" + obj.name);
9.  
10.             inputMiktar = obj.GetComponent<InputField>();
11.             Debug.Log("Input Miktar:" + inputMiktar.ToString());

Log with 0 is unimportant another thing

79. line :

Code (CSharp):

1. verdiginFiyatGosterge.text = "$ " + inputMiktar.text;

your code isnt assign

full code, its like dealer's life game

 

I'm not sure about what causes that error in line 79. Didn't read the full code.

But strings are objects, and objects can be null. So you should check your string before using it. Otherwise you might get a null reference exception, because your variable might be null:

Code (CSharp):

1. // a string with null value
2. string myText = null;
3.  
4. // check before using
5. if (string.IsNullOrEmpty(myText) == false)
6. {
7.     // string wasn't empty, print string
8.     Debug.Log("MyText:" + myText.ToString());
9. }
10. else
11. {
12.     // string was empty, do something else
13.     Debug.Log("MyText: -");
14. }

Note. If you are ever considering sharing your code or asking questions related to your code, always use english language for variables. It is not a native language for many of us, but using english makes it more likely you'll get answers.

 

thanks try other object and inputfield its worked now i am rebuilding the trouble inputfield
