Variables are assigned but it returns null

Questions & Answers

I can’t figure out what’s the error in my code.
I call the function Load from the Game Manager, but it returns null even if the variables are assigned in the inspector.

part of Game Manager:

GameObject [] test = DeathLoad.instance.Load()
print(test); //it returns null

Here’s my death load script, which is called from the Game Manager.

DeathLoad:

public class DeathLoad : MonoBehaviour{
public static DeathLoad instance;
//Screens are assigned in the inspector
public GameObject [] screens;
void Awake()
{
    if(instance == null) instance = this;
}

public GameObject[] Load()
{
    return screens;
}

}

I tried to call the method inside the DeathLoad and it works, but I need to call It from the Game Manager.

Assuming that you don’t get any runtime error in the code you’re providing, the only reason this could happen is that you have two instances of your “DeathLoad” class.

Try this in your Awake method

void Awake()
{
    Debug.Log("DeathLoad::Awake", this);
    if(instance == null)
        instance = this;
    else
        Debug.Log("Error instance is not null", instance);
}

If you see more than two of these logs there’s something wrong in your setup. When you click on the debug log message, Unity will highlight the context object so you can find the instance that you’ve stored in your singleton variable.

Note that if you do get runtime errors you have to provide your actual code and tell us exactly what error you get and in which line.

first get ‘DeathLoad’ class from you gameobject (which gameobject have attach this script). then call your Load() function.
ex:
GameObject ClassObject = Gameobject.Find(“—Your gameObject—”);
var DeathLoadclass = ClassObject .getcomponet();
DeathLoadclass .Load();
