Question

我正在尝试设置一种方法将产品放入我的商店，并且在调用方法后代码不会执行。它不会抛出任何错误，它只是不执行，我无法弄清楚为什么。

继承调用AddProduct的地方

void Start()
{
    try
    {
        db = GameObject.Find("Database").GetComponent<Database>();
        dm = GameObject.Find("DispensaryManager").GetComponent<DispensaryManager>();
        AddProduct();
    }
    catch (NullReferenceException)
    {
        print("Database is null");
    }
}

代码在第5行之后停止运行：

public void AddProduct()
{ // This method is called one time during the Start() method of its gameobject
    List<StoreObjectReference> jars = db.GetProducts(StoreObjectReference.productType.jar); // this is not null
    GameObject jar = Instantiate(jars[3].gameObject_); // successfully instantiates
    jar.AddComponent<Jar>();
    jar.GetComponent<Jar>().product = new StorageJar(jar);
    print("This prints"); // This prints
    ProductPosition jarPosition = dm.dispensary.Storage_cs[0].GetRandomStorageLocation(); // Storage_cs[0] is not null
    print("This doesnt print"); // Never reached
    jar.transform.position = jarPosition.transform.position; // Never reached
}

继承人GetRandomStorageLocation（）

public ProductPosition GetRandomStorageLocation()
{ // Does not throw any errors
    print("Getting product position"); // This prints
    return storageShelves[0].positions[0]; // This does exist, I am only hardcoding the two indexes for testing purposes
}

执行代码后，这是控制台的screenshot

这是ProductPosition

public class ProductPosition : MonoBehaviour
{
    public Product product; // the product stored here
    public Vector3 positon; // position for products stored here
}

代码在方法调用后停止执行
