How can I Get and Set visual script variables from c#

Unity Engine
1

I am using Unity 2020.3 I have a saved variable in script machine an I’ll try to access this variable.

using UnityEngine.Purchasing;
//using System;
using UnityEngine;
//using UnityObject = UnityEngine.Object;
//using Ludiq;
//using Bolt;
using Unity.VisualScripting;
using System;

public class TestCodes : MonoBehaviour
{
//public int lola = (int)Unity.VisualScripting.Variables.Saved.Get(“Coins”);
//var lola = (int)Unity.VisualScripting.Variables.Object(totik).Get(“Coins”);
//public int altin = (int)Variables.Saved.Get(“Coins”);
// public int altin = public static Variables.Saved.Get(“Coins”);
//public int altin = (int)Variables.Saved.Get(“Coins”);
// public int altin = public static Variables.Saved.Get(“Coins”);
}

I’m not familiar with the visual scripting module(s), but from a quick search of the documentation, it looks you’re on the right track?

using Bolt;
using Ludiq;
using System;
using UnityEngine;
using Unity.VisualScripting;

public class TestCode : MonoBehaviour
{
   public int coins;

   private void Start()
   {
       coins = (int)Variables.Saved.Get("Coins");
   }
}

Most of your code is commented out? Is this intentional? Also, you have ‘public static’ in your variable assignment.

This way still doesn’t work???
Red line warning line “coins = (int)Variables.Saved.Get(“Coins”);”

using UnityEngine.Purchasing;
using UnityEngine;
using Unity.VisualScripting;

[IncludeInSettings(true)]

public class IAPCodes : MonoBehaviour
{
public static int coins;
public static int sonuc;

public static void Tata()
{
coins = (int)Variables.Saved.Get(“Coins”);
Debug.Log(coins);
sonuc = coins + 100;
Debug.Log(sonuc);
Variables.Saved.Set(“Coins”, sonuc);
}

public string Onaltin = “com.fefe.gerere.10coin”;
public string Ellialtin = “com.fefe.gerere.50coin”;
public string Yuzaltin = “com.fefe.gerere.100coin”;

public void OnPurchaseComplete(UnityEngine.Purchasing.Product product)
{

if (product.definition.id == Onaltin)
{
Debug.Log(“Purchased 100 coins!”);
Tata();

}
if (product.definition.id == Ellialtin)
{
Debug.Log(“Purchased 500 coins!”);

}
if (product.definition.id == Yuzaltin)
{
Debug.Log(“Purchased 1000 coins!”);

}
}
public void OnPurchaseFailed(UnityEngine.Purchasing.Product product,PurchaseFailureReason reson)
{
Debug.Log(" nedeni ile olumsuz!");
}

}

Try doing coins = (int)(Variables.Saved.Get("Coins"));. This specifies that you want to convert whatever the Get method returns, not the Variables class.

public static void Tata()
{
coins = (int)Variables.Saved.Get(“Coins”);
Debug.Log(coins);
sonuc = coins + 100;
Debug.Log(sonuc);
Variables.Saved.Set(“Coins”, sonuc);
}

change to :

public void Tata()
{
coins = (int)Variables.Saved.Get(“Coins”);
Debug.Log(coins);
sonuc = coins + 100;
Debug.Log(sonuc);
Variables.Saved.Set(“Coins”, sonuc);
}
