How to make a Dialogue System in Unity

[@micahgoins4918]

10:50 ATTENTION!! if using a newer version of unity and you try to use "Text - TextMessagePro" it will not work!! to get the code to work just change the "public Text nametext;" variable to "public TextMeshProUGUI nametext;" and do the same for the dialogue text variable!

[@micahgoins4918]

also at the top put "using TMPro;"

[@Ian640]

@MeebleMeeble it would help if you would post a link to the official Unity video you're talking about so those of us can compare the foundation Brackeys gave us with a more advanced example like what you're mentioning. I did a quick search over the unity channel and I haven't seen anything focused on Dialogue. I found a few that touched on the subject but talked more about interactivity than what Brackeys has shown.

[@BoundfoxStudios]

you mean the courses? yeah many courses are very shit :D

[@Ian640]

+MeebleMeeble Thanks for posting the link! From what I understand Brackeys is all about, for the mass population that tell themselves "Oh man I _wish_ I could make a game but don't know how..." Brackeys creates a strong, understandable, readable foundation that really rolls out the red carpet to the juicy center of Unity, Game Development, and Scripting's full potential. I think Asbjørn himself mentioned within his podcast linked in this video the history of Brackeys and the purpose as to why it was made, and why the format is now what it is. It's a cool history :D I also believe that he and Sofie (Sofibab? Sofi?) read the comments almost feverishly so they can see what they can do better to increase the quality of content put out, so mentioning the scrolling text reformatting itself could invoke another video, or start an entire "Dialogue pt 2", which would be super awesome as I love dialogue systems myself. On another note, much of learning code in general is a self endeavor. To be able to solve problems that appear before you that you can solve yourself is challenging and rewarding at the same time! Although Brackeys didn't mention how to solve the re-aligning of text printing to the game, doesn't it make you curious how you could solve it yourself, now that you know how to code such a system and understand the imput it takes? :) It intrigues me!

[@jacoblynam923]

totally agree! This dude is a stud!!!

Put in the simplest way, Brackeys helps you more to understand the logic and algorithm while unity courses are more flexible coding wise.

[@xenothym]

Thank you for this nice tutorial! I paused the game during the dialogue. For those of you who want to do the same, set the Update Mode of the Animator to "Unscaled Time", then instead of "yield return null" use "yield return new WaitForSecondsRealtime(typingSpeed)" where typingSpeed is a float variable storing the time delay between the appearance of the characters. Finally, all that is left to do is to set "Time.timeScale = 0" in the StartDialogue method and to set "Time.timeScale = 1" in the EndDialogue method.

Thank you Brackeys, you make things stupid simple. Programming in Unity is really cool. I need to watch this a few times and do it, save it and make notes everywhere.

[@TheLunarElixir]

[@SKGaming-gs4ul]

This was great Brackeys! And I love how it's so easy to add your own custom features onto it. I made it so that you can't skip the text until it's finished animating :).

[@Hypericus82]

SK Gaming that drives me mad in games!!

[@madlad255]

It depends on what you're doing, but I'd recommend making it so that pressing 'Continue' when the text is still going will make it automatically put the whole thing in. I haven't tried this, but it doesn't look too hard to implement.

[@IndieMarkus]

I love the visuals and idea with the queue system! However, when you have a game with a lot of dialogue (eg. an RPG), you should rather use external text files for storing conversations. XML or Json - for example - could be used there. This enables you to write dialogues in a more lightweight environment (notepad++), is more expandable and - most importantly - makes your game easily translatable later on.

[@IndieMarkus]

Hmm, I don't really know, since I didn't learn it from KZbin, but in University. First of all you should learn how XML is structured syntactically. It's not really that hard - especially when you know how html works (which is based on xml). In Unity you can import xml files as assets of type "TextAsset". This is how you can load a file in Unity answers.unity3d.com/answers/63443/view.html Within the c# script you can then use XmlDocument to parse your xml file(s). This short stackoverflow answer gives you an idea on how this could look like: stackoverflow.com/a/55840/6330074

[@waterandtreefilms]

Very good Point.

[@ayli765]

OR, if you are not very good at this, like me, you could just leave the name fields blank, and put the name of the character speaking at the beginning of each text block.

[@anirudhganesh7714]

@@IndieMarkus For games that have extensive conversations, this method would work really good. Although I'm here just for making a prototype and this is more than enough for me. So I think this is a good starting point for beginners and this itself might be too complicated for some people.

[@stickguy9109]

I am a bit late for this reply but I am wondering if you can make some kind of a basic programming language for that. You write your code in a .txt file and c# reads and compiles that. Something like: Say "Hello I am NPC";

[@tommyyodergamecreator]

For all who want the button that displays the next text to be interactable after the text finishes here is the code. I just stumbled on this while working on some game updates. IEnumerator TypeSentence(string sentence) { storyText.text = ""; foreach(char letter in sentence.ToCharArray()) { storyText.text += letter; yield return null; } skipButton.interactable = true; } I hope this helps you out! :)

[@tommyyodergamecreator]

If you are using a controller. public void DisplayNextSentence() { if(sentences.Count == 0) { EndStory(); return; } skipButton.interactable = false; string sentence = sentences.Dequeue(); StopAllCoroutines(); StartCoroutine(TypeSentence(sentence)); } IEnumerator TypeSentence(string sentence) { storyText.text = ""; foreach(char letter in sentence.ToCharArray()) { storyText.text += letter; yield return null; } GameObject.Find("EventSystem").GetComponent().SetSelectedGameObject(firstObject, null); skipButton.interactable = true; }

[@TS111WASD]

Very nice, this helped me so thanks. Instead of the skip button, I used a bool called "isTalking" because my dialogue is interacted through pressing the "E" key. I also made it so you could speed up the text after pressing continue twice, and the boolean makes it so you still can't skip until the text is finished. public void DisplayNextSentence() { if (sentences.Count == 0) { EndDialogue(); return; } typeSpeed = 0.02f; isTalking = true; string sentence = sentences.Dequeue(); StopAllCoroutines(); StartCoroutine(TypeSentence(sentence)); } IEnumerator TypeSentence(string sentence) { dialogueText.text = ""; foreach (char letter in sentence.ToCharArray()) { dialogueText.text += letter; yield return new WaitForSeconds(typeSpeed); } isTalking = false; } void Update() { if (Input.GetKeyDown("e")) { typeSpeed = 0f; if (!isTalking) { DisplayNextSentence(); } } }

[@Dezomm]

If you are getting problems with null reference exceptions with your "sentences" variable, (error should first appear on sentences.Clear() if you are following Brackeys exactly) probably its because you are calling StartDialogue() before Start() is called at all (which is where the sentences variable is initialized). HOW TO FIX: You can fix this by changing Start() to Awake() in your DialogueManager.cs script. Awake() is called BEFORE ANYTHING ELSE in the script., while Start() is only guaranteed to be called before the first frame, which can cause some hard to find errors...

[@ind1ewave]

This Aged Well

[@leliba13]

Great as always! maybe a choice system (with a node editor) could be nice!! I was thinking something along the lines of the following structure: Dialogue:{ Character {Name, picture, tone} Text Choices[{name, () => enabled? , Dialogue, () => effect}] } If Choices is null or empty, then it means it's the end of conversation. If there is only one choice, then it works similar to the list you use in your system. enabled -> boolean function meant to check conditions by which you can access this part of conversation (quest completed? enough lv? etc) effect -> void function which makes it possible for the Dialogue choice to affect the game world (for example () => character.evil++) picture -> for example, face of the talking character. tone -> could be an enum, which sets the style of the text

[@신채훈-j2i]

Here's Korean student learning Unity. This video is veeeeeeeeeeery useful to make my own game. Thanks for your education.

[@AkaGiant1]

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; } } }

How would i implement this in a scenario where two characters are having a conversation via text boxes? What i mean, how would i alternate one active textbox with the other? Thank you kindly!

Likely just have the continue button in that scenario activate another script instead of continuing the current dialogue box. Alternatively, you could forgo the name box and put it in yourself.

[@SaadTahirVelocity7]

Man your tutorials are simply amazing. I just ended up watching ten of your tutorials and learnt a lot. I wanted to make a dialog system between two person but I couldn't understand your method. So I just changed the Dialogue class having a single name and sentence string elements. Then I made an array of dialogues in Dialogue Trigger class. Then I called those sentences and names one by one. And WALAH! I was able to show those dialogues with different names and sentences. However I don't understand the way you told in here. Thanks!

[@Charditronic]

That's great! But if you need diferent characters talking... I supose that we need to do transform the variable "Dialogue" (from DialogueTrigger script) in a Array (like this "Dialogue [ ]" ). But... How can we do for Start the next Dialogue? I supose we must create a function in DialogueManager script, but I don't know what to do... :'(

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.

[@mars9399]

This is so cool. I tried both Brackey's and Black Thorn Pod's tutorials but they weren't a good fit. Brackey's, had a lot more going on and it ended up not working when I wanted to change some things up. (less flexible. won't work unless you copy and paste his template) Black Thorn Pod was amazing at explaining things and made it really easy to understand, but his idea to invalidate the next button until the sentence finishes playing didn't end up working for me. The sentence would finish, and the next button would just stop working inside 'play'. This tutorial has both the flexibility of Brackey's and the ease of use as Black Thorn Pod's. You make it really easy to follow--almost a breeze--and has all the functionality I need. I removed the audio function as I didn't need it. And because you made it so easy to understand, it was easy to do that, and it didn't end up with any errors. Plus, you helped pretty much everyone in the comment section with their ideas, which I think you have the ability to do so as the subscriber count is still small.

I'm having a problem with the FindObjectOfType function bc it returns this message when I click on the button: Object reference not set to an instance of an object

[@jaososchefget3632]

i had this issue too, my problem was I had for some reason changed the start function in the dialogue manager so it wasn't being called. so the Queue sentences that we created wasn't being given a value at the start, and when the code tried to call on sentences it didn't have anything to call on.

[@jaososchefget3632]

Also, I don't fully understand this at all, but I was messing around with calling the script from a separate object than the button, and because dialogue manager had been placed on the button first when I was following the tutorial, the script wasn't running through my other instance of dialogue manager until after I had deleted the button object.

[@jaososchefget3632]

AND for some reason every time I open the unity project again, I have to delete and add the Dialogue Manager to the object again?? maybe somebody who understands this a little better can explain that

[@jaososchefget3632]

for me, the dialogue manager was being called on start, but since it creates the queue on start, it wasn't ready, so it would create this error. to fix i just changed it to create the queue on awake, so when it's called on start that's already been done. leaving these all here in case somebody else has the same problem in the future and finds this useful lol.

I know this is a very old comment, but for those that need it, I created a system that starts the dialogue by pressing "e" whenever you're close to the character in question. It has however a bug when talking to multiple characters that use the same trigger script, so you should use different ones. Put this inside TriggerDialogue: private bool firstTime == false; void OnTriggerStay(Collider other) { if (other.tag == "Player"){ if(Input.GetKeyDown(KeyCode.E) && firstTime == false){ FindObjectOfType().StartDialogue(dialogue); firstTime = true; if (Input.GetKeyDown(KeyCode.E) && firstTime == true FindObjectOfType().DisplayNextSentence(); } } } EDIT: The player must have a second, bigger collider set as "trigger" and must be tagged appropriately.

nullReferenceException: object reference not set to an instance of an object DialogueManager.StartDialogue(Dialogue dialogue) (at Asset/DialogueManager.cs:19) can anyone help?

[@exinr6930]

i'm having a similar issue i have no clue what I'm doing wrong.

[@BedWords_]

@@exinr6930 I think this happens when you forget to drag your Text objects over to the appropriate slot in the DialogManager component section in the Editor. In other words, it's not pointing to a specific Text object.

This was not particulary what i was searching for, but i couldn't stop myself watching it through..

[@tobycook9039]

how do I add multiple of these at once? n my game I have multiple npc's and when you run into them, your character stop and it activates the text box. each NPC has a dialogue trigger with their own names and text. but because have multiple of these on one scene, whenever i speak to an npc they all say the same text from one dialogue trigger and i dont know how to fix it plz help.

[@tobycook9039]

Nvm i fixed it, i was using FindObjectOfType to find the trigger now i’m using collision.gameObject.GetComponent and it works, also you can but sounds in the foreach statement and i makes a sound every time they talk and also the speed they talk, i controll this using strings

[@nineth-lion]

How can you change the speed at which they talk? I mean the speed each individual character shows on screen. I tried using WaitForSeconds instead of yield return null but it's too slow.

[@kittenish7116]

use wait for secnods but have iit low like 0.02 (i used thaat) Edit: Oh god my grammar holy crap... D;

[@Firestar-rm8df]

@@kittenish7116 wait for seconds is a bit janky imo. You want to create a character buffer in the coroutine that uses delta time to add a certain number of characters since the last frame, and use floats, not ints to count characters and add the partial character overflow to the number of characters to print out next frame each time, so the remainder keeps rolling over to the next print creating smoother printing.

Thank you! *I had a little issue while using textmeshpro, I could'nt use it in the public variable on the inspector at the Dialogue manager. I turned it into regular text and the issue was solved. I'd like to know is there is a way to use TMP though! Thanks again! It works great!

[@anoncoms]

I have the same question, would love an answer!

[@RodolpheJL]

you have to tell you're using tmp so insert this at the beginning of your code : using TMPro; Then you have to use TextMeshProUGUI for the texts you use : public TextMeshProUGUI nameText; public TextMeshProUGUI dialogueText;

[@elllieeeeeeeeeeeeeeeeeeeeeeeee]

(top of file) using TMPro; Instead of "Text" use class "TextMeshProUGUI" or "TMP_Text"

Great tutorial. The only thing I want to mention is that this is a tutorial for a monologue system. I think with a little transfer you can manage to get a dialogue system, but nothing for noobs like me

[@GameDevJosh]

How do you get rid of the "Start Conversation" button after the dialogue button has begun?

[@GameDevJosh]

Never mind I solved it. I might have done it a bad way but I called the button in a FindObjectOfType().SetActive(false); inside of the void TriggerDialogue(){} . Hey if it works it works. If anyone knows of a better solution please comment

[@jackunlocker3125]

Better way is: Not "FindObjectOfType" but make "public Button startButton" in your TriggerDialogue and drag that button into that slot in the editor. So it will be just "startButton..SetActive(false);" Good luck ;)

[@rimoros.1020]

instead of a public button, make it a GameObject instead, only using the button only disables the button script

[@lucky-two]

[@nicospadoni5328]

You can call the trigger function on "Start", and the continue ones on a different function(such as update, or OnTriggerStay).

[@skeleton_king]

2 years old and still perfect. Good work!

[@pollyrain9217]

I had issues with implementing this code for multiple NPCs. I would get a NullReferenceExeption and only one NPC at a time would show the text. What I did to solve that issue, was create a public DialogueManager dialogeManager and then assign the dialogManager like this in the code: dialogeManager.StartDialogue(dialogue); in the TriggerDialogue() function. In the Inspector I would drag the DialogManager in the DialogTrigger Script panel. In case anybody runs agains that issue, too.

How to change the Trigger ? , i mean i dont need a button to Start the dialogue, i want when i open the Scene that dialoguebox is automatically appear in scene ? Sorry for my bad English , Thanks Before

[@silvestrequeiruga8122]

Just dispatch the Method StartConversation wherever you want. For example if you need to start the dialogue when the player enters in a room ypu can set a collider at the entrande and create a Method void OnTriggerEnter (Collider other) { if(other == player) //set a layer or tag for this { DialogueManger.StartConversatio(); } }

[@silvestrequeiruga8122]

Check the following: - You set the tag of the player as "Player"? - Make sure you add the DialogueManager script to a object in the scene. - Make sure you add the DialogueTrigger to the object that contains the boxcollider2D. - Make sure that the boxcollider2D is marked as isTrigger and the player have a rigidBody2d. (sorry for the bad english).

[@silvestrequeiruga8122]

Great!. To find a audiosource you need to have the script added to the same object that have the audio source. In the script write: public AudioSource audio; Then in the Start method use: void Start() { audio = GetComponent(); } If you have 2 audiosource in the same object you need to asing them manually in the inspector. Make 2 public variables of type AudioSource in your script, add the script to the object with the audiosources and drag and drop them.

[@silvestrequeiruga8122]

In that case you need to asing it manually in the inspector or use the following: var AudioSource audio; void Start { audio = FindObjectWithTag(``Theobjectwithaudiosourcetag´´).GetComponent(); }

[@silvestrequeiruga8122]

Mmm.. in that case the only way i know if assing it manually in the inspector. Dont know any way made trough code.

How to make dialog between two or more characters using this system ?

[@mirageowl]

I'm not an expert but here is a quick idea: Expand the Dialogue class with 2 more variables: bool hasFollowup, Dialogue followupDialogue Then go to DialogueManager script and find DisplayNextSentence() method. Inside the if(...) replace EndDialogue and have a code like this: if(dialogue.hasFollowup) { StartDialogue(dialogue.followupDialogue); } else { EndDialogue(); }

[@mirageowl]

I was thinking a way to edit followupDialogue, so I came up with this: you can add followupDialogue variable to DialogueTrigger and edit it there and pass it to the dialogue object before callinng StartDialogue on it. This was more messy than I though so probably something else can be done.

[@EnjiRouz]

MirageOwl Actually I've found the best way to do it Just make dialogs array in the trigger And make queue of dialogs in manager, not phrases Fix some errors And that should do it :) You should make Dialog class like class with one phrase (not array) and one name

That makes sense, thanks!

​@@useless3310 It's not only the script, somehow the object in Unity is connected to the script. They work in unison. To see exactly where the problem is, try to debug it. Print a message with your conversations size ( Debug.Log("conversations size: " + conversations.Length) ) and at every step and see where things go wrong. I've changed the dialogue a lot since I started. I'm using ScriptableObject(s) now. The error suggests you are trying to access an element in the array although it doesn't have the size of the requested index. Something like: conversations has length 3 and you try to get conversations[3] (the three elements being at indexes 0,1 and 2).

I know this is old but what I do (though it's probably very inefficient) is turn the name into a queue as well and just update it every time the "DisplayNextLine" function is called. (Just without typing it) Then you can jest set the name queue to be the same length as the Lines queue and change the name every time the character speaking changes in the dialogue. Hope this helps (If you even still needed it) =)
