@@PandemoniumGameDev thx

Dude, thank you so much, you saved my game!

bless you man. i was struggling with this

This is really high praise, thank you! Episode 2 is 50% done, it won't have branching dialogue unfortunately, will leave that for episode 3 I guess.

Pandemonium Games Excited for an episode 2 and beyond! Even getting these attached to certain NPCs to trigger sequences would be AWESOME. Thanks!

@@rmcquade19 Managed to get rid of that error?

Ah, thank you for the kind words! I'll keep putting up content and hopefully people will find it :). BTW episode 2 of this series is being recorded now.

more than happy to help :)

Hey man, this means the world to me, thanks!

Thank you for this comment! It now works for me

soo true bestie!!! thank you

hey thanks a ton! You mean to make this more advanced? Branching dialogue and stuff?

@@PandemoniumGameDev Yes please!

@@moonstonestudios8719 you got it, I'll do my best to make some time for it this week

@@PandemoniumGameDev thank you!

It does however work with your unity project. Yours works just fine when I boot it up and play it, after I enable the sprites and sounds that is.

@@holdenthompson1449 It happened to more people, the problem is that the color parameter has 0 opacity, so it's transparent. The text is there you just can't see it. Make sure to change the opacity to 100%.

@@PandemoniumGameDev My God 🤦. How could I be so foolish? Thank you! I appreciate the quick response!

@@holdenthompson1449 as I said, easy to miss. Lotta people got this problem.

@@PandemoniumGameDev I had the same error, thank you very much xD

FIXED dumb me didn’t realize I was using a TextMeshPro object instinctually-still learning!!

How did you solve the problem? Please help I'm always getting NullReferenceException errors...

You're very welcome Toast man :D JK, thanks a ton for watching this :)

it means there is no code that sets those values. Maybe check if you're setting the values correctly?

Abstraction. In this way you can make other scripts that behave differently but still have the ability to show text in way. For example you can make a Cutscene script and make it load the game when it's done, etc. In this case it's not strictly necessary, I agree, but just in case you want to extend it into something more.

I honestly have no idea because I haven't worked with Unreal. I believe the logic should be the same, so that's the good part. The challenge will be to adapt all the code from C#/Unity to C++/Unreal. Good luck, hope you find a way to do it!

Make a UI image and attach a script on it. Use the same logic we used in this tutorial, you make an array of sprites and every time your player presses Space or click, you change the image.sprite = arrayOfSprites[currentImage]. Let me know if it's clear

@@PandemoniumGameDev Awesome, thank you

Go to 14:50, DialogueBaseClass.cs and replace Input.GetMouseButton(0) with Input.GetKeyDown(KeyCode.Space)

@@PandemoniumGameDev thanks man

Thanks my man :D

check the DialogueBaseClass and see if you have the WriteText Ienumerator there. Check the name and make sure it's marked as protected, not private. Also check if DialogueLine class is inheriting from DialogueBaseClass not MonoBehaviour

@@PandemoniumGameDev Thanks, man, what went wrong is that I switched DialogueBaseClass to MonoBehaviour, on DialogueLine

@@UpBeeGames yep, no inheritance, no access to WriteText. Glad you found it.

It just fixed itself nevermind.

Sure, you can do that easily. Notice the line I added after Input.GetMouseButton(0), that's the one you need, you'll also need to replace "_newSound" that I added in there, you'll figure it out, good luck :) public class DialogueBaseClass : MonoBehaviour { public bool finished { get; private set; } protected IEnumerator WriteText(string input, Text textHolder, Color textColor, Font textFont, float delay, AudioClip sound, float delayBetweenLines) { textHolder.color = textColor; textHolder.font = textFont; for (int i = 0; i < input.Length; i++) { textHolder.text += input[i]; SoundManager.instance.PlaySound(sound); yield return new WaitForSeconds(delay); } //yield return new WaitForSeconds(delayBetweenLines); yield return new WaitUntil(() => Input.GetMouseButton(0)); SoundManager.instance.PlaySound(_newSound); //Sound that plays between lines, you need to replace _newSound with an Audioclip finished = true; } }

@@PandemoniumGameDev Awesome that worked! Last question, haha. Do you know if I can add the ability to change text color, font, or facing (bold, italic, underline) of individual strings in the text?

@@sudahi51 harder to do with this system, will think about it but for now I'd recommend to put this stuff in a different line.

@@PandemoniumGameDev this absolute chad took out the time to paste the code for a confused commenter. sub earned

@@inxendere thanks :D I try to do it on all my videos

muchas gracias :D

xd

3:27 i followed all the code and steps but the Example Text didn't appear when I went into playmode. do you know why?

For the the font and color not existing it just means that you forgot to reference them, after the line '' private Text textHolder; " Add the two following lines lines : [SerializeField] private Font textFont; [SerializeField] private Color textColor;

Did you make finished public in the DialogueBaseClass.cs?

@@PandemoniumGameDev it was public already so i'm not sure what the problem is

@@enigmatic3280 also check it DialogueLine.cs is inheriting from DialogueBaseClass.cs. Otherwise not sure, you may need to go through all the code again or download the complete project from the link in the description

I assume you're trying to say that is shows the first letter then it stops. It must be an error in this case, check your console and check the code.

The fact that the sound plays perfectly means this exception is happening only once I assume. I think you're trying to start the dialogue in the Awake() method in some script. If that's the case change the Awake() to Start(). The problem is that the SoundManager.instance is being created in Awake, and you're trying to access it in another Awake and it's not ready. Let me know if that's the case.

@@PandemoniumGameDev I was stuck with this problem for 2 hours. Thanks for the help!

The way you solve it is by attaching the DialogueHolder script to the text box UI!

@@jibyap7790 bro you just saved my entire project thanks so much

That's not a part of this project, it's a cutscene from Undertale. You could make it tweaking this system though, just need add the image to each dialogue line, and to create the fade effect you can use a CanvasGroup component.

Hey Stig, thanks a lot, really appreciate it! Regarding your idea, yeah I could make something like that for you by the end of this week, stay tuned ;) PS: don't worry that you have a lot of IF/ELSE statements for now, it's a part of the learning process, just make your game work and continue to improve gradually :) we all start out as beginners

@@PandemoniumGameDev Great :D Awsome :D oh ok hehe, That`s true, some times i have read my old code and improved it sort of hehe, few days ago i actually fixed&improved my sniper/scope script :)

Make sure the color is correct, if you have black text on black background it might not be visible. That's just a guess if that's not it let me know

@@PandemoniumGameDev Yeah my colors are correct and the text is just not appearing. When I'm selected on the "Text" icon I can still see the script loading each letter one by one, but it doesn't appear in the actual game.

Late reply, sorry about that. Are you getting any errors?

@@PandemoniumGameDev I fixed it but thanks for reply anyway :)

I was stuck at the exact same problem. After I also got stuck with the color part not showing any text, and the solution being that oppacity was 0 by standart, I expected my mistake to be something similiar this time too... I solved it by adding an audio Listener to the scene....

@@flekiblue444 I solved by writing my own audio manager.

You're trying to do something like this: if mouse is clicked skip the line, otherwise if player waits X seconds skip the line automatically?

@@PandemoniumGameDev Exactly. I trying to do that.

​@@fromoldcity this is not very elegant but it works: if(Input.GetMouseButton(0)) yield return new WaitUntil(() => Input.GetMouseButton(0)); else yield return new WaitForSeconds(2); finished = true;

@@PandemoniumGameDev I Used your new code for my game. Only one problem left that i'm faced. In this method; if I dont click mouse button, all 4 dialogue lines passed and finished nicely by order of 2 seconds row.

need more info to help you. Which component? The DialogueLine.cs? And are you getting any errors?

@@PandemoniumGameDev dont think i have any errors but ill try to find some if i do

@@Cakestarr alright, you can DM me on discord to solve this faster

Here's the code: using UnityEngine; using System.Collections; namespace DialogueSystem { public class DialogueHolder : MonoBehaviour { private void Awake() { StartCoroutine(dialogueSequence()); } private IEnumerable dialogueSequence() { for (int i = 0; i < transform.childCount; i++) { Deactivate(); transform.GetChild(i).gameObject.SetActive(true); yield return new WaitUntil(()=>transform.GetChild(i).GetComponent().finished); } } private void Deactivate() { for (int i = 0; i < transform.childCount; i++) { transform.GetChild(i).gameObject.SetActive(false); } } } }

nvm I found the mistake, i wrote ienumerable instead of ienumerator ;)

Check if your dialogue holder in Unity doesn't have any other stuff except dialogue lines. You should only have dialogue lines there, otherwise it's searching for a dialogue line component and can't find it therefore the null reference.

@@PandemoniumGameDev NVM NVM NVM :DD I fixed all the problems, thanks for your help :D, sorry I deleted all those spam replies lol

I've literally incorporated your unity package of the finished project and it's still doing it. Man :/...

You needed to move the DialogueHolder code you just wrote to the background for the text, which is also called DialogueHolder in the video.

@@alok8744 what do u mean

The text has 0 opacity so it's transparent, make sure to change the color and increase opacity.

​@@PandemoniumGameDevHi, thanks for your response. But I cant find how to increase opacity. When i remove feature with custom color from code, it starts working. Then I've made a line textHolder.color=Color.black in Awake() section and it did everything right. Could you please say where is opacity option in unity? I've searched the net but didn't found info about it

@@annoyingGnome press on the color, and it's the fourth slider on it, you RGB and the fourth is A so opacity

Thanks for this, was really scratching my head to no end over it.

Yeah that's because the sign is => not

@@PandemoniumGameDev thank you :D

how do i make it so an event plays right after the last dialouge box is finished?

@@wutbuffe4734 put it in the DialogueHolder.cs: private IEnumerator dialogueSequence() { if (!dialogueFinished) { for (int i = 0; i < transform.childCount - 1; i++) { DeactivateLines(); transform.GetChild(i).gameObject.SetActive(true); yield return new WaitUntil(() => transform.GetChild(i).GetComponent().finished); } } else { DeactivateLines(); int index = transform.childCount - 1; transform.GetChild(index).gameObject.SetActive(true); yield return new WaitUntil(() => transform.GetChild(index).GetComponent().finished); } gameObject.SetActive(false); dialogueFinished = true; //put your event here! }

@@PandemoniumGameDev thanks this helped so much!

The exception is on line 19 of DialogueBaseClass.cs so 2 options: 1. Soundmanager instance is missing 2. textHolder is missing. But from what you said that S appears then it stops it seems like you have a problem with the SoundManager, check if you create an instance of it inside Awake() or if the object is present in the scene at all.

Try in DialogueLine get "StartCoroutine..." from Awake() and put it to Update() and add IF statement to it (for example: if you push SPACE, then dialog will start). I have same problem. And it help

Or just make in DialogueBaseClass.cs something like this: if(sound != null) { SoundManagerScr.instance.PlaySound(sound); }

Thanks! The battle system is not on my list yet, you can check out this video though: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-XjGHyKBSkX4.html

For me, the alpha of the text was at 0. You can change it when change the color. Underneath the RGB values, you'll find Alpha values.

@@dingusproductions3708 thanks a lot, I fixed problem by this solution

That's the trick here, you don't write the text into the text section, you write it in your Dialogue Line(Script) component, there's an input field there for it. Hope this helps :)

@@PandemoniumGameDev yeah I did that. I write it in the input section of the script and it shows it typing in my text section on the text gameobject, but I don't see it in game. Just the blank dialog box image.

@@toxiconflict Weird, did you make the script run in Editor Mode? If not follow the video or alternatively just download the entire project, link is in the description. Let me know how it goes :)

@@PandemoniumGameDev I'm having the exact same error. Maybe has it something to do with the DialogueLine being a DialogueBase class, instead of a Monobehaviour one?? How do you run the script in Editor Mode?

@@edywiiii DialogueBaseClass derives from Monobehaviour, therefore the DialogueLine class also derives from it + the DialogueBaseClass. Now it you get an error try checking the log, maybe there's something else causing it. If you still can't figure it out download the complete project(link in description), as you can see in the video it's working, tried to run it now and it works fine.

Glad to hear it helped, I've been reading all your messages and I can't wait to make another episode. Finishing one of my jobs this week and making the new episode this weekend for sure, it will include everything you wanted in the comment.

Meanwhile, if you need a quick solution here's what I did in a couple minutes: 1. find a way to activate/deactivate DialogueHolder object from another script. 2. use the changes I did below and it will work every time you you want to start the dialogue again //Dialogue holder using System.Collections; using UnityEngine; namespace DialogueSystem { public class DialogueHolder : MonoBehaviour { private void OnEnable() { StartCoroutine(dialogueSequence()); } private IEnumerator dialogueSequence() { for (int i = 0; i < transform.childCount; i++) { Deactivate(); transform.GetChild(i).gameObject.SetActive(true); yield return new WaitUntil(() => transform.GetChild(i).GetComponent().finished); } gameObject.SetActive(false); } private void Deactivate() { for (int i = 0; i < transform.childCount; i++) { transform.GetChild(i).gameObject.SetActive(false); transform.GetChild(i).GetComponent().ResetLine(); } } } } //DialogueBaseClass using System.Collections; using UnityEngine; using UnityEngine.UI; namespace DialogueSystem { public class DialogueBaseClass : MonoBehaviour { public bool finished { get; set; } protected IEnumerator WriteText(string input, Text textHolder, Color textColor, Font textFont, float delay, AudioClip sound, float delayBetweenLines) { textHolder.color = textColor; textHolder.font = textFont; for (int i = 0; i < input.Length; i++) { textHolder.text += input[i]; SoundManager.instance.PlaySound(sound); yield return new WaitForSeconds(delay); } //yield return new WaitForSeconds(delayBetweenLines); yield return new WaitUntil(() => Input.GetMouseButton(0)); finished = true; } } } //DialogueLine using UnityEngine; using UnityEngine.UI; namespace DialogueSystem { public class DialogueLine : DialogueBaseClass { private Text textHolder; [Header ("Text Options")] [SerializeField] private string input; [SerializeField] private Color textColor; [SerializeField] private Font textFont; [Header("Time parameters")] [SerializeField] private float delay; [SerializeField] private float delayBetweenLines; [Header("Sound")] [SerializeField] private AudioClip sound; [Header("Character Image")] [SerializeField] private Sprite characterSprite; [SerializeField] private Image imageHolder; private void Awake() { imageHolder.sprite = characterSprite; imageHolder.preserveAspect = true; ResetLine(); } public void ResetLine() { textHolder = GetComponent(); textHolder.text = ""; finished = false; } private void OnEnable() { StartCoroutine(WriteText(input, textHolder, textColor, textFont, delay, sound, delayBetweenLines)); } } }

@@isabelebenevinuto2637 WriteText is not a preset function, it's one I made, that's why TextMesh doesn't have it built it. Instead what you want to do is this: public class DialogueBaseClass : MonoBehaviour { public bool finished { get; set; } protected IEnumerator WriteText(string input, TextMeshPro textHolder, Color textColor, TMP_FontAsset textFont, float delay, AudioClip sound, float delayBetweenLines) { textHolder.color = textColor; textHolder.font = textFont; for (int i = 0; i < input.Length; i++) { textHolder.text += input[i]; SoundManager.instance.PlaySound(sound); yield return new WaitForSeconds(delay); } yield return new WaitUntil(() => Input.GetMouseButton(0)); finished = true; } } Notice that the logic is the same but I replaced Text with TextMeshPro and Font with TMP_FontAsset, it will work now if you everything else right.
