5 Minute DIALOGUE SYSTEM in UNITY Tutorial

Dialog? Dialogue? Either way, in this Unity Tutorial we'll be looking at adding a simple system into our game that types out sentences one character at a time.
Dialogue systems can get pretty elaborate, and this solution is obviously not going to support anything extensive, but its a great starting point for just being able to get a narrative into your game and interactions with NPCs.
In the video I have the conversation being triggered by the Start method of our script, but you could use triggers or key inputs to call StartDialogue() from any way that you'd want.

For those who are confused as to where to put your text. When you go to the DialogueBox’s inspector, underneath the Dialogue script tab, there’s another tab called ‘Lines’. That’s where you add it! :)

[@user-sd6mp8jv2v]

nice

[@amyguzman3502]

Hm weird, I cannot find it

[@amyguzman3502]

nvm just found it!

[@agustinquindimil6594]

I can put this script anywhere and then call it when I press "e" lets say, right?

[@igseatsyursoul]

Finally a dialogue that is basic with no bells and whistles that I can fully customize. Too many of the other tutorials on this added way more than I want for my small game.

[@LaneWatson]

Ahh yes. Got my 5 minute fix. The most useful tutorials on Unity.

[@BMoDev]

Haha thanks! Appreciate ya

Most efficient Unity tutorial I've ever seen--and it makes perfect sense! You just made my day. And, my first subscribed channel ever. Thank you.

[@djt3rrv875]

God thank you SO MUCH for including the complete on click function!!!! A lot of tutorials don't, and it really sucks as a player to be waiting and waiting for this shit to type itself out (especially if you read fast). Such a clean and clear cut tutorial!!! Thank you!!!

Is there anyway to add this to multiple game objects and have the dialogue system come up when the game object is interacted with in some way? I've tried so many tutorials and methods and have been stuck for days.

[@arrexu01]

Question. How would I be able to mix this with a multiple choice dialogue system?. Like, say my player would have a voice line, then naturally the npc would respond, but only once and the conversation is done. So what I mean is, how can i transition between both?

[@nevimkde9537]

Absolutely love this video!!! Helped a lot, but I have a question. If I wanted to make multiple instances of waiting function for some reason code doesnt execute them at all. If I have multiple IEnumerators nor If I have If function in one IEnumerator, there it will only execute the original and if I change the text appearance to that another if statement it will completely skip any dialogue at all (my main reason of doing this if because the character not always speaks at same speed e.g. if he is surprised he will swallow some of his words or in cutscener or non-interactable dialogue which will appear and dissapear of its own). Thank you if you are willing to help me!

[@hejhejhej952]

Thank you kind sir!

[@wicksley]

Awesome thank you :D

[@madpenguin58]

Hi @BMo! Is there some kind of way that one could add some kind of trigger collider on something like a sign or NPC and have the character hit a button like the space key in order to start the dialogue instead of having it start at the beginning of the game? I have tried some things myself but I just can't figure this one out. Thanks!

[@BMoDev]

Yeah 100%, you just need that trigger to execute the StartDialogue method. I have an "Interaction" tutorial, you can use the principals in that to call the StartDialogue Method! kzbin.info/www/bejne/mX3deGR-eciAatU

[@madpenguin58]

@@BMoDev Ok! Thank you very much! I was also wondering (sorry I have so many questions. I should probably just get better at code on my own.) if there was some kind of way to implement a response, and have the dialogue loop back to the beginning every time you play it. Thanks! I have been following a bunch of your 2D tutorials and am learning a lot about making games!

[@patrickalexander1737]

And is it possible to add images in the background that transition with the dialogues?

[@infosource3153]

Excellent

[@animationanimator5143]

Is there a way so that certain elements aren't said in the dialogue box until the player reaches a certain point?

[@NAgamerOfficialYT]

is there a way to make it pause for a small moment for stuff like commas or something like that?

[@awawa5594]

How do you give control back to the main game after dialogue ends? I'm having difficulties wording what I mean but after the dialogue runs using this method, I want to then get objects to show or be able to click on buttons but I don't want to add that code directly in the Dialog Manager as it'd make it messy and not specific to the dialog but I don't know how else to do it?

[@arianrivaz5982]

hey.thanks for the great video.any ways i could use this twice? for example.i have a nurse charecter.first she starts the dialogue.then after she finished i would like to use this method once again on my player charecter and (for example answer the nurse).i would really apreciate if you answer.

[@Val0r2]

Question: How would I go about making new dialogue appear whenever my player returns to the same scene instead of it just repeating same stuff every time the scene is loaded?

[@jordanthebestlass8483]

how do i keep the the text from moving when i have it's alighnment centered?

[@connorwilson-long1336]

Any easy way to reset this when coming back for more dialogue? It works if I just set the index to 0 and change the dialogue lines, but it is blank at first and when it doesn't do the animation for the first line either.

[@Tea-qk6ii]

hey u gotta do an if/else statement to say something like if talked to then (else) this action can happen

[@lorenzoaielli4605]

Ok, that's cool and all, but how did you make the actual different lines of dialogue? Where did you put them specifically?

[@evannationarmy7769]

In the DialogueBox, where you attached the Dialogue Script, there should be a menu that says Lines. You can set how many lines you want and type in what you want them to say.
