[Solved] Create linked nodes with code

[ichisan]

Hi Tony. Sorry, I need your help again,
I have massive text to input (5k lines in spreadsheet). So I think it's easier for me to export the spreadsheet, put the text, and then import it.
So, to do that, I need to automatically create numbers of nodes, which is I tried, but the outcome is not what I want it. Here's the code:

Code: Select all

[ExecuteInEditMode]
public class AddchildDialogueManager : MonoBehaviour
{
    public bool execute = false;
    public DialogueDatabase db;
    public int idConversation = 0;
    public int numberCreate = 0;
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        if (execute)
        {
            List <DialogueEntry> entries = db.conversations[idConversation].dialogueEntries;
            for(int i=0; i < numberCreate; i++)
            {
                DialogueEntry prevEntry = entries[entries.Count - 1];
                DialogueEntry entry = new DialogueEntry();
                entry.id = entries[entries.Count - 1].id + 1;
                prevEntry.outgoingLinks.Add(new Link(idConversation, prevEntry.id, idConversation, entry.id));
                entries.Add(entry);
            }
            db.conversations[idConversation].dialogueEntries = entries;
            execute = false;
        }
    }
}

And the output become like this :


And it gaves me this null refference errors:

NullReferenceException: Object reference not set to an instance of an object

Do you have solution for this? Thank you...

Hi,

Use the Template class. If the script runs in the editor, you can use TemplateTools.LoadFromEditorPrefs() to get a Template class that uses any template fields you've set up in the Dialogue Editor's Templates section. Otherwise use Template.FromDefault() like the example below. This example creates a new database and adds a conversation with a START node and one actual node:

Code: Select all

// Create database:
var database = ScriptableObject.CreateInstance<DialogueDatabase>();

// Create a template, which provides helper methods for creating database content:
var template = Template.FromDefault();

// Create actors:
int playerID = template.GetNextActorID(database);
database.actors.Add(template.CreateActor(playerID, "Player", true));
int npcID = template.GetNextActorID(database);
database.actors.Add(template.CreateActor(npcID, "NPC", false));

// Create a conversation: [ID 0=START] --> [ID 1=Hello]
int conversationID = template.GetNextConversationID(database);
var conversationTitle = "My Conversation";
var conversation = template.CreateConversation(conversationID, conversationTitle);
conversation.ActorID = playerID;
conversation.ConversantID = npcID;
database.conversations.Add(conversation);

// START node: (Every conversation starts with a START node with ID 0)
var startNode = template.CreateDialogueEntry(0, conversation.id, "START");
node.ActorID = playerID;
node.ConversantID = npcID;
startNode.Sequence = "None()"; // START node usually shouldn't play a sequence.
conversation.dialogueEntries.Add(startNode);

// Actual dialogue node ("Hello") with ID 1: (could have used template.GetNextDialogueEntryID)
var helloNode = template.CreateDialogueEntry(1, conversation.id, string.Empty);
helloNode.ActorID = npcID; // NPC speaks this line.
helloNode.ConversantID = playerID;
helloNode.DialogueText = "Hello";
conversation.dialogueEntries.Add(helloNode);

// Link from START to Hello:
var link = new Link(conversation.id, startNode.id, conversation.id, node.id);
startNode.outgoingLinks.Add(link);

// And what the heck - might as well add it to the runtime environment and play it:
DialogueManager.AddDatabase(database);
DialogueManager.StartConversation(conversationTitle);

Thankyou Tony, it works. You help a lot
For anyone who have same problem, this my codes:

Code: Select all

using System.Collections.Generic;
using UnityEngine;
using PixelCrushers.DialogueSystem;
using System.Linq;

[ExecuteInEditMode]
public class AddchildDialogueManager : MonoBehaviour
{
    public bool execute = false;
    public DialogueDatabase database;
    public int conversationID = 0;
    public int numberCreate = 0;
    private int lastId = 0;

    // Update is called once per frame
    void Update()
    {
        if (execute && database.conversations.Any(x => x.id == conversationID))
        {
            Conversation conversation = database.conversations.Find(x => x.id == conversationID);
            List<DialogueEntry> entries = conversation.dialogueEntries;
            
            var template = Template.FromDefault();
           

            for (int i = 0; i < numberCreate; i++)
            {
                DialogueEntry lastEntry = entries[entries.Count - 1];
                int nextEntry = template.GetNextDialogueEntryID(conversation);
                var newNode = template.CreateDialogueEntry(nextEntry,conversation.id, string.Empty);
                if(database.actors.Any(x=>!x.IsPlayer))
                    newNode.ActorID = database.actors.Find(x=> !x.IsPlayer).id; // NPC speaks this line.
                else
                {
                    int npcID = template.GetNextActorID(database);
                    database.actors.Add(template.CreateActor(npcID, "NPC", false));
                    newNode.ActorID = npcID;
                }
                if (database.actors.Any(x => x.IsPlayer))
                    newNode.ConversantID = database.actors.Find(x=>x.IsPlayer).id;
                else
                {
                    int playerID = template.GetNextActorID(database);
                    database.actors.Add(template.CreateActor(playerID, "Player", true));
                    newNode.conversationID = playerID;
                }
                newNode.DialogueText = string.Empty;
                Rect newNodeRect = lastEntry.canvasRect;
                newNodeRect.y += 50;
                newNode.canvasRect = newNodeRect;
                entries.Add(newNode);
                
                var link = new Link(conversation.id,lastEntry.id, conversation.id, nextEntry);
                lastEntry.outgoingLinks.Add(link);
            }
            Debug.Log("Done");
        } else
        {
            Debug.Log("No data found");
        }
        execute = false;
    }
}

Cheers.
