How do I access a script from a class inside a script.

Question

 public class ShopUpgrades : MonoBehaviour
 {
     [System.Serializable]
     public class Upgrade
     {
         public bool upgradeType {get; set;} // true == Click, false == Passive
         public string name {get; set;}
         public float upgrade_multiplier {get; set;}
         public int max_level {get; set;}        
         public int current_level = 0;
         public float price {get; set;}
         public bool isMax = false;
         public bool isAvailable {get; set;}
         
         public void UpgradeObject(ref GameObject upgrade_interface) {
             if (current_level != max_level) { //Increments the current level by one
                 current_level++;
             }
             GetComponent<Budget_tracker>().budget += upgrade_multiplier;
         }
     }
     
 }

In line 19 I want to access a script named "Budget_tracker" which is inside the same game object with the ShopUpgrades script. I need to modify "Budget_tracker"s variables in the "UpgradeObject" method of "Upgrade" class. I cannot do it in "ShopUpgrades" script because I also need to assign "Upgrade" objects in that script:

     public Upgrade someUpgrade = new Upgrade{
         upgradeType = true,
         name = "someUpgrade",
         upgrade_multiplier = 2,
         max_level = 5,
         price = 10,
         isAvailable = true,
     };
 
     public Upgrade someUpgrade2 = new Upgrade { 
         upgradeType = false,
         name = "UpgradeName2",
         upgrade_multiplier = 2,
         max_level = 5,
         price = 10,
         isAvailable = true,
     };

Unless you pass a reference to the ShopUpgrades object along when instantiating an Upgrade you simply don't.

A "normal" class which is not derived from a Monobehaviour has no concept of GetComponent.

So add a constructor to Upgrade and a private field to contain the ShopUpgrades class.

Could you demonstrate it a little bit on the code. I am really confused :(

something like this:

 [System.Serializable]
 public class Upgrade
 {
     private readonly ShopUpgrade _shopUpgrade;
     public Upgrade(ShopUpgrade shopUpgrade)
     {
         _shopUpgrade = shopUpgrade;
     }
 
     public UpgradeObject(...)
     {
         //instead of GetComponent<Budget_tracker>() use:
         _shopUpgrade.GetComponent<Budget_tracker>().....
     }
 }
