Error with modifying variables when function is called from button click

[Kreezy-Studios]

Sorry for the confusing title, but I ran into an issue that I haven't been able to fix for the past week

I have a public int testing that is set to 0 at the start of the game. I have a button that when clicked, it adds +1 to the "testing" integer.
However, I can see that within the function being called, "testing" is being modified and added to, but it doesn't change to the inspector and instead stays at 0. But, when I add to the integer outside of the function being called on button click (like Update method), the variable changes in the inspector.

Any idea how to resolve this?

It's hard to say exactly what's going on without better understanding your setup. Perhaps you could share the code (or even the whole script for more context) modifying public int testing?

Also, are you using a custom editor or property drawer to display the testing variable?

[Kreezy-Studios]

Sorry for the missing context, but here's the code:

`public class ButtonManager : MonoBehaviour
{
public int testing = 0;

// Start is called before the first frame update
void Start()
{
  testing = 0;
}

public void SelectFarmableType(GameObject uiPanel)
{
      Debug.Log("Pressed");
  testing++;
}

}`

I had a whole different class setup that didn't work so I stripped it down to those and just tried changing the testing variable but the issue persisted. I have SelectFarmableType being called when I click a panel.

I'd like to add, the variable changes on the inspector after I end the game

Also, when the variable is modified directly within the script in an update method with a timer, it changes in the inspector with no issue. This only when it's called with the Button script

Thank you for the code! I believe I was able to recreate your setup and now think I see what's going on. When I click the button I get this exception in the console:

ArgumentException: Object of type 'UnityEngine.Object' cannot be converted to type 'UnityEngine.GameObject'.

And, at least in my setup, I was getting the error when I left the argument displayed in the inspector as None

If I assign that field to a game object or if I change the method to not have any parameters like so:

public void SelectFarmableType()
{
      Debug.Log("Pressed");
      testing++;
}

then clicking the button in the scene does increment testing as expected, and it updates in the inspector.

In your project do you have that field assigned and/or are you seeing any errors in the console when you click the button?

For what it's worth, this behavior is not coming from Nova. I hit the same issue using UGUI buttons - it appears to be a limitation of Unity's serialized events, at least in the version of Unity I used for testing (2022.2.1f1).

Thanks for the quick replies.

The Game Object is assigned to an actual game object and "pressed" does appear in the console. The "UIManager" object is an empty game object on my hierarchy completely separate from my UI elements. Not sure if that could be causing the issue.

[Kreezy-Studios]

I figured it out. The "UIManager" object was being modified on the prefab I have saved live and not on the "UIManager" I have on the hierarchy

Sorry for the waste of time

Thank you

No worries! Just glad to hear you got to the bottom of it!
