I have an error NotImplementedException: The method or operation is not implemented.

this happens whenever I test my game, it loads up fine but, when I press space bar to proceed with the text, since i'm creating a dialogue system, I get the error shown in the title of this post.
Here's screenshots of the error i'm getting & below is the link to the youtube video tutorial I've been using to create this code, any help would be much appreciated. this is my first post on the forum, so sorry if i've missed anything out, for what I need to do with this post.

 

i'm new to coding, just so people know.

 

so i deleted that public void not implemented bit, in dialogue system but now i have an error on line 32 in the character.cs which say 'dialogue.Say(speech, characterName);', the characterName is giving me an error called Argument 2: cannot convert from 'string' to 'bool' ?

 

i deleted it cos the video tutorial playlist i'm following from, didn't have/use the code i deleted (probably cos i used a solution on the code in visual studio that i wasn't meant to) his code even though i followed it correctly gives me errors, altho for him, he has no problems?

 

also i have no idea where to start with learning C# seems very daunting

 

Dialog systems are complex just by their very nature.

Starting with a dialog tree processor is sort of like choosing a battleship for your first shipbuilding project.

First ship would probably be more successful if you tried a canoe.

I recommend working through about a dozen smaller simple tutorials, steadily building confidence in what is going on.

Brackeys makes great videos, as does Unity. Work through some of the easiest shortest ones there, and build up your skeelz, and then move onto more complicated things.

 

thanks, for the advice i'll have a look brackeys and unity tutorials, i appreciate it.
