Hello there,

You call “AddNewDialogue” by passing in your variable “dialogue”, but the function is expecting TWO arguments, not ONE. It expects an array of strings called “lines”, as well as a string called “npcName”.

The fix would be to pass in your NPC name as well as the dialogue:

DialogueManager.Instance.AddNewDialogue(dialogue, myNpcName);

I hope that helps!

Cheers,

Bacon missed that the first ‘string’ is a ‘string array’ and not just a string.

I have made an explanation of Overloads here applied to ‘Instantiate’ but the reasoning is the same.

In a nutshell, arguments to a Function must match exactly in type.

When you call a function (or Invoke) you do not repeat the arguments as they are written in the constructor, for their name… you simply feed in what it wants according to type… it can be from ANY similarly typed variable. If you dont quite understand this you could look at it here .
