Accessing scriptable object classes class from other script

Question

Hello, How do I access a scriptable object classes class from other script. Im trying to get the string[] and select randomly array from it and display it as a text.

 using UnityEngine;
     using System.Collections;
     using UnityEngine.UI;
     
     public class Scriptable : ScriptableObject {
     
         #region singleton
         public static Scriptable instance;
         public static Scriptable Instance
     {
         get{if(instance == null) instance = Resources.Load("Scriptable") as 
     
     Scriptable; return instance;}
     }
         #endregion
     
         [System.Serializable]
              public  class Info{
                public string text;
             [Space()]
             public float price = 0f;
             public bool somethingElse = false;
             public bool somethingMore = false;
             public bool somethingEvenMore = false;
             public bool thisIsSomething = false;
             public bool somethingSomething = false;
        }
          public  Info[] info;
  }

and the script where I access it with is here

  using System.Collections;
     using System.Collections.Generic;
     using UnityEngine;
     using UnityEngine.UI;
     
     public class handler : MonoBehaviour {
     
                     public Scriptable script;
                     public Text thisText; 
                     public string randomStringSelected;
   
        void Start () {
        Scriptable = transform.GetComponent<Scriptable> ();
     
             if (script)
                 {
                        randomStringSelected = script.info.text.RandomItem();
                       thisText.text = randomStringSelected.toString();
     }
 
 
 }
 
 }

Well, firstly, ScriptableObjects aren't components, and therefore you can't get them with GetComponent; they're essentially user-defined Asset types. Components are attached to GameObjects, while ScriptableObjects are never attached directly to GameObjects -- you create instances of your ScriptableObject type, and then those instances exist as individual files, and you can link them to your scripts like you would a texture or an audio file.

The easiest way to make an instance of your Scriptable asset type is to add [CreateAssetMenu] above the class definition, like this:

 [CreateAssetMenu]
 public class Scriptable : ScriptableObject {
     // etc

and then you can right-click in one of your asset folders and the option to create a Scriptable asset will be there, and you can edit that asset from the inspector.

Now, you have an asset file of your Scriptable asset type. Since your handler class has the field public Scriptable script;, you can drag your Scriptable asset to that field in that script's inspector, and now your script has a reference to that asset. Now your Start function can look like:

 void Start()
 {
     if (this.script != null)
     {
         this.randomStringSelected = this.script.info.text.RandomItem(); // see below
         this.thisText = randomStringSelected.ToString();
     }
 }

Mind you, the line I marked in that (copied from your code sample) is incorrect, and has several problems with it. To get a random string from your Scriptable asset, this is one way you could do that:

 this.randomStringSelected = this.script.info[UnityEngine.Random.Range(0, this.script.info.Length)].text;
