UI Text: Words at end of line jumping to next line
I was coding a dialogue system with autotyping, I made a coroutine and just noticed the words at the end of a line jumped to next line. So in case someone else is wondering how to fix this issue, here is my solution.
private IEnumerator AutoType (Text textUI, string text) {
yield return null;
textUI.text = text;
Canvas.ForceUpdateCanvases();
textUI.text = string.Empty;
text = GetFormattedText(textUI, text);
for (int i = 0; i < text.Length; i++) {
textUI.text = text.Substring(0, i + 1);
yield return new WaitForSeconds(0.025f);
}
}
private string GetFormattedText (Text textUI, string text) {
string[] words = text.Split(' ');
int width = Mathf.FloorToInt(textUI.rectTransform.sizeDelta.x);
int space = GetWordSize(" ", textUI.font, textUI.fontSize);
string newText = string.Empty;
int count = 0;
for (int i = 0; i < words.Length; i++) {
int size = GetWordSize(words[i], textUI.font, textUI.fontSize);
if (i == 0) {
newText += words[i];
count += size;
}
else if (count + space > width || count + space + size > width) {
newText += "\n";
newText += words[i];
count = size;
}
else if (count + space + size <= width) {
newText += " " + words[i];
count += space + size;
}
}
return newText;
}
private int GetWordSize (string word, Font font, int fontSize) {
char[] arr = word.ToCharArray();
CharacterInfo info;
int size = 0;
for (int i = 0; i < arr.Length; i++) {
font.GetCharacterInfo(arr[i], out info, fontSize);
size += info.advance;
}
return size;
}
So basically I get the width of each word and the I check if it fits inside the RectTransform.
