Awesome tutorial! Quick question, do you know how you could insert a standalone sound effects between dialogue lines? Like after the player mouse clicks past a line of dialogue an effect like a glass break or something plays before the next text line reads?

[@PandemoniumGameDev]

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; } }

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

Hey, first of all, thank you very much for this tutorial, its awesome! Im new to Unity, I'm a media science student from germany and we are programming our first game, so this video really helps! I dont know if you'll read this and if you can help me out, but I do have a question. I get a nullreferenceexception error with this line "SoundManager.instance.PlaySound(sound);" even though the sound plays perfectly. I would be really happy if you could help me out! And thanks again!

[@PandemoniumGameDev]

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.

My code is exact (im pretty sure) to what is in your video, but these errors come up anyway. Is there something I may have done incorrectly to cause these?

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;

What is the advantage of making DialogueBaseClass and inheriting it? So what if we write the WriteText function directly into the DialogueLine script?

[@PandemoniumGameDev]

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.

Hey! Thanks for the tutorial! I've actually figured out how to trigger the dialogue after pressing a key while in a certain place. Yet, I can't understand how can I create a system with infinitely repeating lines. I want it to work this way, but can't understand how to implement it: - Start dialogue - Text being written - End of dialogue - Start again - The same text being written again - End - Start again And on and on like this. I've tried everything out, but when I start a dialogue again it just prints the last line of dialogue and doesn't let me close it. And also, how can I make it so when I press a certain key the line prints fully, so I can skip waiting for the line to end? Please, make a video explaining this topic. I've searched all throughout the Internet and haven't found anything useful!

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

How come when I get to step "Adding Custom Color and Font for each dialogue line" the text input isn't visible when I press play?

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.

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 :)

Eg: If i want to show "I am hero :D", it displays "II am hero :D"

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.

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
