how to display a long string sentence by sentence instead of character by character?

Question

Hi, I am new to Unity. I get the following code from this http://answers.unity3d.com/questions/11151/multi-line-label-with-different-font, instead of type-writing it character by character, I would like to make it display sentence by sentence, is there any one know how to do it? Thanks for helping me solve the problem.

var gFont : Font; var letterPause = 0.01; var Story : int = 1; var words : String = ""; var fontStyle : GUIStyle; private var word;

function Start () { if(Story == 1) { word = "Today is a beautiful sunny day.\n I had fun with my family.\n etc....."; } TypeText(); }

function TypeText() { for (var letter in word.ToCharArray()) { words += letter; yield WaitForSeconds (letterPause); }
}

function OnGUI() { GUI.skin.font = gFont;

GUI.Label(Rect(250,80,1000,500),words,fontStyle);

}

I would recommend using the method string.Split() with a string array.

For example in Javascript, if you had

var Sentences : String[];
var myString = "This is the first sentence. This is the second sentence.";

You could use the split method like so:

Sentences = myString.Split("."[0]);

This will split the sentences at each period (which means you'll need to add the periods later). What you get from the above is that Sentences[0] is "This is the first sentence", and Sentences[1] comes out to be "This is the second sentence"

Then instead of using an invoke to grab the next letter, you can just use the invoke to grab the next Sentence[n];

EDIT:

If you'll be using other punctuation for sentences, you would probably do this:

Sentences = myString.Split("."[0], "!"[0], "?"[0], ":"[0]);

the split method needs characters, not strings, which is why we have to add [0], which grabs the first (and only) character in the strings we're using.

EDIT 2 : Per your request, here's an example of how to change the script to show delayed sentences:

var gFont : Font; var letterPause = 0.01; var Story : int = 1; var words : String = ""; var fontStyle : GUIStyle;

private var sentences : String[];
private var word;

function Start (){

 if(Story == 1) { 
     word = "Today is a beautiful sunny day.\n-I had fun with my family.\n-etc.....";    
 } 

 sentences = word.Split("-"[0]); 
 TypeText();

function TypeText(){ 
    for (var line in sentences){ 
        words += line; 
        yield WaitForSeconds (letterPause); 
    }
}

function OnGUI() { 
    GUI.skin.font = gFont;
    GUI.Label(Rect(250,80,1000,500),words, fontStyle);
}

This will work well if you don't plan to use any dashes "-". It's set up to split sentences at dashes you put between them, that way you can still include punctuation. At the start of this script we're splitting up the sentences and storing it in a string array called "sentences". Then, instead of grabbing the characters of the whole string, we're cycling through each sentence that is in our "sentences" array.

Do you $$anonymous$$d to give me an example of the script? and how to add the delay in each sentences, do I still need to use this function?

function TypeText() { for (var letter in word.ToCharArray()) { words += letter; yield WaitForSeconds (letterPause); }

based on above "var letter in word.ToCharArray()", how I should change it so that it can function properly in string ins$$anonymous$$d of char?

I want to display something like this:

This is the first sentence. This is the second sentence.

I'll try to give a hand with this soon if no one else does before tuesday. When I say the method needs characters, I only mean for deter$$anonymous$$ing where to split the strings. It will still return strings fine, I was just explaining the purpose of [0] next to the delimiters.
