"A dialogue system with scriptable objects, a system to choose multiple options being able to activate dialogue from an npc and with an events system so you can make things happen in the game Also you get new dialogue when talking to a character again"

To create a dialogue system with scriptable objects, multiple options, activation from an NPC, and an events system, follow these steps:

1. Create a Dialogue class to store dialogue information.

```csharp
using UnityEngine;

[CreateAssetMenu(fileName = "New Dialogue", menuName = "Dialogue")]
public class Dialogue : ScriptableObject
{
    public string npcName;
    [TextArea(3, 10)]
    public string[] sentences;
    public DialogueOption[] options;
}

[System.Serializable]
public class DialogueOption
{
    public string optionText;
    public Dialogue nextDialogue;
    public UnityEvent optionEvent;
}
```

2. Create a DialogueManager to handle displaying the dialogue.

```csharp
using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using UnityEngine.Events;

public class DialogueManager : MonoBehaviour
{
    public Text npcNameText;
    public Text dialogueText;
    public GameObject optionsContainer;
    public Button optionPrefab;

private Queue<string> sentences;
    private Dialogue currentDialogue;

void Start()
    {
        sentences = new Queue<string>();
    }

public void StartDialogue(Dialogue dialogue)
    {
        currentDialogue = dialogue;
        npcNameText.text = dialogue.npcName;
        sentences.Clear();

foreach (string sentence in dialogue.sentences)
        {
            sentences.Enqueue(sentence);
        }

DisplayNextSentence();
    }

public void DisplayNextSentence()
    {
        if (sentences.Count == 0)
        {
            EndDialogue();
            return;
        }

string sentence = sentences.Dequeue();
        dialogueText.text = sentence;

UpdateOptions();
    }

private void UpdateOptions()
    {
        foreach (Transform child in optionsContainer.transform)
        {
            Destroy(child.gameObject);
        }

for (int i = 0; i < currentDialogue.options.Length; i++)
        {
            Button optionButton = Instantiate(optionPrefab, optionsContainer.transform);
            optionButton.GetComponentInChildren<Text>().text = currentDialogue.options[i].optionText;
            int index = i;
            optionButton.onClick.AddListener(() => SelectOption(index));
        }
    }

public void SelectOption(int index)
    {
        if (currentDialogue.options[index].optionEvent != null)
        {
            currentDialogue.options[index].optionEvent.Invoke();
        }

if (currentDialogue.options[index].nextDialogue != null)
        {
            StartDialogue(currentDialogue.options[index].nextDialogue);
        }
        else
        {
            EndDialogue();
        }
    }

void EndDialogue()
    {
        Debug.Log("End of conversation.");
    }
}
```

3. Create an NPC class to trigger dialogue.

```csharp
using UnityEngine;

public class NPC : MonoBehaviour
{
    public Dialogue dialogue;
    public DialogueManager dialogueManager;

void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            dialogueManager.StartDialogue(dialogue);
        }
    }

void OnTriggerExit(Collider other)
    {
        if (other.CompareTag("Player"))
        {
            dialogueManager.EndDialogue();
        }
    }
}
```

4. Set up your scene with UI elements for displaying dialogue and options, and an NPC with a collider.

5. Create scriptable objects for your dialogues and set up the options and events as needed.

Now you should have a functioning dialogue system with multiple options, activation from an NPC, and an events system. To make new dialogues appear when talking to a character again, you can create additional Dialogue scriptable objects and assign them as nextDialogue in the DialogueOption class.
