How to make a Dialogue System in Unity

If your code does not work: check if you misspelled
if you did everything right and you can't press button: add event system(dialogue box>>right click>>UI>>event system
If you are using text mesh pro and does not work: delete and use text and do as same as in the video
If my comment helped you let me know and like so other people can see too

For anyone getting null reference error in sentences.Clear(); because you are calling automatically from a void start(), u could make a Invoke("mymethod", 0.5); where mymethod would be the startDialogue(dialog); and "0.5" seconds to before trigger it. it works for me because i want the dialog start almost before loading the scene.

if anyone is having an issue where the console keeps displaying "object reference not set to an instance of an object" and points you to the dialogue manager script, my fix was changing sentences.Clear(); to sentences = new Queue<string>(); and the issue was gone, idk why it was making a fuss but it did for me, also make sure not to set a scope on the trigger procedure because it gave me the same error 😀

I've rewatch this to many times.

If you want the text to appear faster/slower you can do something like this (it could be crap but it works)
IEnumerator TypeSentence (string sentence)

{

DialogueText.text = "";

foreach (char letter in sentence.ToCharArray())

{

DialogueText.text += letter;

for (int i = 0; i < 10; i++)
// Change "10" to change the speed of the writing
{

yield return null;

}

}

}

Did anyone else think, "Damn it Visual Studio, why do you always open on the monitor that playing video?", when Brackeys opened up Visual Studio?

Why in foreach fragment (below) there is foreach(string sentence in dialogue.sentences) not foreach(string sentence in sentences). I don't understand what dialogue.sentence here is for.

I am asking about this fragment of code:

public void StartDialogue(Dialogue dialogue)

{

Debug.Log("Starting conversation with " + dialogue.name);

sentences.Clear();

foreach (string sentence in dialogue.sentences)

{

sentences.Enqueue(sentence);

}

DisplayNextSentence();

}

how to make it so it do it automatically?, like i dont want to press it. just by itself

This is better than other paid ones. (Unity got still the best Tuts but they created Unity and they are a big company)

well damn, that was simpler than I thought it would be

Como adicionar esse dialogo em um npc para ativar na tecla "SPACE"?
How to add this dialog in an npc to activate on the "SPACE" key?

dude no joke u saved me a lot of trouble thank u so much for letting us download the project

How do I close the dialogue box after the last line of text? Any suggestions, instead of just a debug log inside of the EndDialog method in the dialogManager script.

Dude, how do you save this thing? Can you make a tutorial for saving dialogue?

how would I go about adding an image of the speaker/NPC for each sentence? eg. one sentence the character is appears to be sad, so to go along that sentence a portrait of the character appearing sad is displayed in the dialogue box, much like a lot of RPGs out there.

I am loving this system! Except… can anyone tell me why some objects with dialogue trigger skip their first line? If it were a consistent bug I could just leave the first line blank on each trigger, but it only happens on some objects!
