struct and stepping? (quest line)

So my concept was:

• Quest Handler - a monobehaviour class which handles the quests, which quest is selected at the moment in the questline, can be placed on the player.

• Questline - a scripltable object so i can create several questlines

• Quest - a scriptable object which is basically the quest itself.

So I am halfway there but I will publish the solution regarding my question:

Quest Handler

public class QuestHandler : MonoBehaviour { public Quest quest; public Questline questline;

 public int QuestlineIndex;

 public void Update()
 {
     if (Input.GetKeyDown(KeyCode.Space))
     NextQuest();
 }

 public void NextQuest()
 {
     if (QuestlineIndex < questline.QuestLines.Length)
     {
         DisplayNextQuest();
         Debug.Log(quest);
         QuestlineIndex += 1;
     } else {
         QuestlineIndex = 0;
     }
 }

 public void DisplayNextQuest()
 {
     QuestLine line = questline.QuestLines[QuestlineIndex];
     quest = line.quest;
 }

  **Questline**
  
 
   [CreateAssetMenu(fileName = "New Questline", menuName= "Inventory System/Quest/new Questline")] [System.Serializable] public class Questline : ScriptableObject {
     public QuestLine[] QuestLines; }
 
 [System.Serializable] public struct QuestLine {
     public Quest quest; }

 

 **Quest**
 
 public enum QuestType
 {
     Cook
 }
 
 [System.Serializable]
 public class Quest : ScriptableObject
 {
     public int ID;
     public QuestType type;
     public ItemObject toCook;
     public int howMuchToGather;
 }

I will update if I have the full system :)
