Access a class on another script?

If your one script defined a class called SlotInv, you can't access it through any other name, other than SlotInv. You might want to rename your class to Inventory to match the rest of your code.

Your Script 2 is also not complete, it sort of looks like you're trying to write UnityScript in C#. You can't have variables and functions outside of a class.

For future reference, you should always post the exceptions you are getting so that we can give better responses. Right now I'm literally just guessing why your scripts aren't compiling.

Try this idea

  private SlotInv  slotScript;

  public string x;

  void Start()
  {
    
    slotScript = GameObject.Find ("Quad").GetComponent<SlotInv>();

    x = slotScript.VariableName ;// accessing variable

    slotScript.FunctionName();// accessing function

  }
 

You can access public class features like

• public functions

   public void SampleFunction()// This function can access by another script 
  
     {
       //  some code 
     }
  
     void XFunction()// This function cannot access by another script
  
     {
       //  some code 
     }
   
  
   
  

• public static variables

     public static bool isButtonPress1 ;//  This variable can access by another script
  
       private bool isButtonPress2 ; // This variable cannot access by another script
  
  
       public bool isButtonPress3 ;// This variable cannot access by another script
  

Thank you for your comment, first to clarify some things (I should have posted on the question) both scripts inherit from monobehaviour. The only error I'm getting is this one:

Assets/Scripts/Inventory/RecipeDataBase.cs(55,16): error CS0118: RecipeDataBase.RecipeItems' is a field' but a `type' was expected

Even if I change in the Start Function to

 RecipeItems= transform.GetComponent<Inventory> ().SlotInv;

I get the same error

Hope this helps

I have seen that coming up previously and in the end a class inside works when the wrapping class is not MonoBehaviour. At least I think it was going this way.

Why are not making your nested class a normal class and use it as you should:

 public class SlotInv {
 
    public int[] ItemIndex;
    public int[] ItemAmount;
 }

 public class Inventario : MonoBehaviour {
         public SlotInv Slot; //Testing
 }

If Inventario is not MonoBehaviour then you can nest and use like

 Inventario.SlotInv

but if a class is meant to be used outside its wrapping class then I don't see the point of it. You declare a class inside another class to use it as a container within the wrapper class, if you need to look into that container from somewhere else then make it easy on you and declare it outside.
