How do I instantiate an Object in another class?

I’m trying this way:

        GameObject Cozinha = new GameObject("CenaCozinha");
        CenaCozinha coz = Cozinha.AddComponent<CenaCozinha>();

But I believe that so he is creating a new Object, hence all that I have already put in the original 'Kitchen' (how to feed lists for example), will not exist in the new.

    You must pass the instance of the object created by a function and save to a property in its new class.

  • um, can exemplify pfvr?

  • I’ll post an answer!

You must pass the instance of the object created by a function and save to a property in its new class. Example:

First create a class that has a property with the desired class type:

public class NewClass
{
    private GameObject _object;
    public void SetObject(GameObject obj)
    {
        _object = obj;
    }
}

After that, enter the new class and pass the object through the created void

GameObject Cozinha = new GameObject("CenaCozinha");
CenaCozinha coz = Cozinha.AddComponent<CenaCozinha>();

NewClass newClass = new NewClass();
newClass.SetObject(coz);

  • Calm down, let me understand, my little Class will not be changed, all this code will be in Newclass (which in my case is Food)...?

    You didn’t make it clear which class is the main one. Newclass would be the class you want to reuse the instance of Cenacozinha. You must instantiate at least once.

  • I’ll put my classes in response

  • Okay, this one up

    From what I understand, you have the Little Girl Class that instantiates the Food Class, right? Then you should put a property in Food with type Cenacozinha and assign its value at the time it is instantiating, Example: public CenaCozinha Cena; novoAlimento.Cena = this;

  • Oh man! It worked! Thank you! D

Here:

public class CenaCozinha : MonoBehaviour { 
//Os Alimentos
public GameObject Alimento;
public GameObject Agua;

public List<Alimentos> alimentosCozinha = new List<Alimentos>();    

void Start () {
}

void Update () {
    foreach (Alimentos al in alimentosCozinha) {
        if (al.nomeAlimento == "agua" && al.quantidade > 0 && !Agua.activeSelf) {
            al.meshAlimento.SetActive(true);
        }
    }
}

public void ComprarAgua() {
    foreach (Alimentos al in alimentosCozinha) {
        if (al.nomeAlimento == "agua"){
            al.quantidade++;
            return;
        }
    }
    Alimentos novoAlimento = Alimento.AddComponent<Alimentos>();
    novoAlimento.id = "agua";
    novoAlimento.nomeAlimento = "agua";
    novoAlimento.quantidade = 1;
    novoAlimento.meshAlimento = Agua;
    alimentosCozinha.Add(novoAlimento); 
}}

And

public class Alimentos : MonoBehaviour { public string id;
public int quantidade;
public string nomeAlimento;
public GameObject meshAlimento;
public string id;

public void Start () {
}

public void Update () {
}

public void OnCollisionEnter2D(Collision2D colisao) {
    if (!colisao.gameObject.CompareTag("Agua")) {
        GameObject Cozinha = new GameObject("CenaCozinha");
        CenaCozinha coz = Cozinha.AddComponent<CenaCozinha>();
        Debug.Log(coz.Alimento);
        Debug.Log(coz.Agua);
        foreach (Alimentos al in coz.alimentosCozinha) {
            Debug.Log(Cozinha);
        }
    }
}}

In Debug.Log(coz.Food); Debug.Log(coz.Water); It returns me Null.
