Text Custom Wrapping

Hello.

I want to make a dialogue box that types each letter one at a time. So far I can do it except that when it reaches the end of the line, it it will write half of a word and then once it writes the next letter, the word wraps and moves to the next line.

What kind of logic do I put in so that it knows to move to the second line straight away instead of typing half of the word first?

 

I've attempted to build the logic from scratch.

How do I figure out how many characters can fit in one line if I am given the width of the Text component?

string currentLine = "";
foreach (string word in pages[pageNumber].Split(' '))
{
if (word.Length > maxLettersInLine)
{
throw new UnityException("Your word is too long!");
}

if ((currentLine + word).Length > maxLettersInLine)
{
textBox.text += "\n";
currentLine = string.Empty;
}

foreach (char letter in word)
{
currentLine += letter;
textBox.text += letter;
yield return new WaitForSeconds(secondsBeforeTypingNextLetter);
}

currentLine += " ";
textBox.text += " ";
}

 

Yeah, this is a bit of a hole in the new UI API; there is no good way to get the width of a string.

But you can get the width of individual characters, using Font.GetCharacterInfo. So you can add these up and figure out where to break your string. See this answer for more details.

 

Are you using a UI Text to display your one letter at a time text?

 

Oh nice Font.GetCharacterInfo.
