Write text letter by letter with return if word does not suit in line
Hey there,
I'm currently using a dialog system where the text is animated letter by letter and it works perfectly except one issue. Because the text is drawn letter by letter and a word does not suit in the line the letters are nevertheless written in the line until the word no longer fits. Then follows a return.
But I would like to check before the animation of another word if the word fits in the line and if not the animation should start in the next line.
Here is my current code:
public Queue<DialogSentence> sentences;
public IEnumerator DisplaySentences()
{
while (sentences.Count > 0)
{
DialogSentence sentence = sentences.Dequeue();
yield return StartCoroutine(TypeSentence(sentence));
}
EndDialog();
}
private IEnumerator TypeSentence(DialogSentence sentence)
{
text.text = shadow.text = "";
foreach(char letter in sentence.sentence.ToCharArray())
{
text.text = shadow.text += letter;
yield return StartCoroutine(WaitForFrames(Settings.textSpeed));
}
yield return StartCoroutine(WaitForCondition(sentence.condition));
}
Just enable wrapping on the text component so it automatically pushes it to the next line? Otherwise you'll have to count howmany letters can fit in one line and manipulate it with a counter variable or something.
This is a messy problem to solve. You would need to keep track of each character's width as it was typed and then insert a new line '\n' when the end of a line was reached.
You can get the width of a character with this:
CharacterInfo info;
text.font.GetCharacterInfo(character, out info, text.fontSize, text.fontStyle);
width=info.advance;
