Has anyone wrapped text of a 3DText object? would be nice to say limit the width, and have the rest auto-resize.
There isnât any obvious way to do this automatically. The TextMesh class doesnât have a method for calculating the width of the string or individual characters, so it is difficult to know where the line breaks should go.
Is there a solid text wrapping solution?
If you mean a plug-in or library, then Iâm not aware of one, but you could try the Unify wiki (I wouldnât get your hopes up, though).
This might not be the best solution, but it worked for me. Maybe someone will find it useful.
I started off with a GUITExt wrapping script, I found somewhere on this forum and then made some adjustments to make it work with my 3D text object.
Simply drag and drop it onto your 3D text object (donât forget to link textObject with your TextMesh) and it should work. For fine tuning, simply alter the maxLineChars integer.
public var textObject : TextMesh;
private var maxLineChars : int = 35; //maximum number of characters per line...experiment with different values to make it work
private var words : String[];
var result = "";
private var charCount : int;
function Start () {
updateText(); //call this function to format your string.
}
function updateText () {
FormatString(textObject.text);
}
function FormatString ( text : String ) {
currentLine = 1;
charCount = 0;
words = text.Split(" "[0]); //Split the string into seperate words
result = "";
for (var index = 0; index < words.length; index++) {
var word = words[index].Trim();
if (index == 0) {
result = words[0];
textObject.text = result;
}
if (index > 0 ) {
charCount += word.Length + 1; //+1, because we assume, that there will be a space after every word
if (charCount <= maxLineChars) {
result += " " + word;
}
else {
charCount = 0;
result += "\n " + word;
}
textObject.text = result;
}
}
}
I was down the road of rendering GUI.Labels into textures ⌠it was⌠mm ⌠not easy.
this is just great, simple efficient.
Thank you !!!
I just add a space at the very beginning of the result so the first word is perfectly left aligned with the others:
textObject.text = " "+result;
Glad you found it helpful.
I was pretty amazed myself, that it actually wasnât that complicated 
Here is a version that is running in the editor.
You can design your layouts without running the game to check your text.
Remove the Update() for the final build or once your layouts are designed - It is only used to refresh your changes made with MaxLineChars.
Iâve added MinLineChars - a very simple limiter to avoid abusive generation of return carriage. otherwise, I did not find a quick and nice way to remove the " " at the beginning of each lines following the first one. So Iâve put a quick hack which adds a " " at the beginning of the first line. That way they are all aligned.

@friendlydeveloper: Thanks again for posting this code in the first place
A text wrap function that also takes other separators into account and gets rid of leading or trailing spaces where needed.
This could be done a bit faster if the program would jump to the max line end and search back from there for a separator.
function WrapTxt(text, width) : String {
var e=text.length;
var i=0;
var lineBegin=0;
var lineLength=0;
var prevSeparatorPos=0;
var wrappedText="";
var separators=" ;:\n\t,.-()@#?";
var cutOffSeparators=" \n\t";
var cutOffSeparator=false;
while(i<e) {
var c = text.Substring(i,1);
i++;
lineLength++;
if(separators.IndexOf(c)>=0) {
prevSeparatorPos=i;
if(cutOffSeparators.IndexOf(c)>=0) cutOffSeparator=true;
else cutOffSeparator=false;
}
if(lineLength>width) {
if(prevSeparatorPos<=lineBegin) prevSeparatorPos=i-1; // no separator found on entire line
if(wrappedText.length>0) wrappedText+="\n";
if(cutOffSeparator) wrappedText+=text.Substring(lineBegin,prevSeparatorPos-lineBegin-1);
else wrappedText+=text.Substring(lineBegin,prevSeparatorPos-lineBegin);
i=prevSeparatorPos;
lineBegin=i;
lineLength=0;
cutOffSeparator=false;
}
}
if(lineBegin<i-1) {
if(prevSeparatorPos<=lineBegin) prevSeparatorPos=i; // no separator found on entire line
if(wrappedText.length>0) wrappedText+="\n";
wrappedText+=text.Substring(lineBegin,i-lineBegin);
}
return wrappedText;
}
Hereâs a very simple way to wrap text:
var myText : String;
var lineLength : int;
for ( var i : int = lineLength; i < myText.length; i += lineLength ) {
var returnSpot : int = myText.IndexOf( " " , i );
myText = myText.Substring( 0, returnSpot ) + "\n" + myText.Substring( returnSpot, myText.length-returnSpot );
Hey,
here is my Word Wrapping, maybe you guys have good ideas for the //OVERFLOW parts, the is the only thing that sucks
// Methode to do LineWrapping
private string formatString(string s){

float fontSize = 0;
// We have 23 lines
string[] lines = {"","","","","","","","","","","","","","","","","","","","","","",""};
int line = 0;
int lineIndex = 0;
// Replace all \n by ÂŽ, cause this is only 1 char
s = s.Replace("\n","ÂŽ");
for (int index = 0; index < s.Length; index++){
// if the line is at the end
if (fontSize >= 1){
int count = 0;
// if we need to wrap the word
while (!s[index].ToString().Equals(" ")){
lineIndex -= 1;
index -= 1;
count += 1;
// OVERFLOW
if (lineIndex == 0){
return "\n\n\nOverflow";
}
}
// delete all chars from the line above
if ( lineIndex < lines[line].Length ){
lines[line] = lines[line].Remove(lineIndex,count);
}
// new line
lines[line] += "\n ";
line += 1;
lineIndex = 0;
}
// new line
if ( s[index].ToString().Equals("ÂŽ") ){
lines[line] += "\n";
line += 1;
lineIndex = -1;
}
lineIndex += 1;
// the other chars
if (!s[index].ToString().Equals("ÂŽ")){
lines[line] += s[index];
}
// OVERFLOW
if (line >= 21){
return "\n\n\nOverflow";
}
// get the size from the text
content.text = lines[line];
fontSize = WbPaletteSystem.instance.textFieldStyle.CalcSize(content).x / 195;
}
for (int i = 0; i < 23; i++){
result += lines[i];
}
return result;
}
no one interested !? I like this way, i just have 2 problems,âŚ
Your solution is excellent but has a couple of issues. You should use LastIndexOf if you want to be certain to keep the text less than the lineLength. Also, in C#, you need to check for a negative return value. Finally, set i to returnSpot so that the next check is exactly a lineLength past then when reverse searching for the next " ". Note, this doesnât address all problems but is pretty nice. Hereâs a C# version:
for (var i=lineLength; i < text.Length; i += lineLength) {
int returnSpot = text.LastIndexOf(" " , i);
if (returnSpot >= 0){
text = text.Substring(0, returnSpot) + â\nâ + text.Substring(returnSpot, text.Length-returnSpot);
i = returnSpot;
}
}

This way you can modify the m_maxWidth value in the editor and use the Gizmos to exactly calculate which max width you want for your TextMesh.
⌠I just hope this hacky solution works on mobile and Unity Engineers donât change how renderer.bounds.extents works
Iâd like to propose my solution. This is a quick and rough implementation for TextMesh objects and can be set to run on start or dynamically by applying the component to the object and then calling the Wrap() function. The differences in my implementation are that Iâm using actual kerning data to determine width, rather than plain character count.
using UnityEngine;
public class WrapTextMesh : MonoBehaviour
{
public bool WrapOnStart;
public float WrapWidth;
public void Wrap(float MaxWidth)
{
TextMesh tm = GetComponent<TextMesh>();
if (tm == null)
{
Debug.LogError("TextMesh component not found.");
return;
}
Font f = tm.font;
string str = tm.text;
int nLastWordInd = 0;
int nIter = 0;
float fCurWidth = 0.0f;
while (nIter < str.Length)
{
// get char info
char c = str[nIter];
CharacterInfo charInfo;
if (!f.GetCharacterInfo(c, out charInfo))
{
Debug.LogError("Unrecognized character encountered (" + (int) c + "): " + c);
return;
}
if (c == ' ')
{
nLastWordInd = nIter; // replace this character with '/n' if breaking here
}
fCurWidth += charInfo.width;
if (fCurWidth >= MaxWidth)
{
str = str.Remove(nLastWordInd, 1);
str = str.Insert(nLastWordInd, "\n");
fCurWidth = 0.0f;
}
++nIter;
}
tm.text = str;
}
// Use this for initialization
void Start()
{
if (WrapOnStart)
Wrap(WrapWidth);
}
}
Just a few notes:
- This doesnât work with âDynamicâ fonts. I tested this only on Uniform, but I imagine it works on other non-dynamic forms just as well.
- Also, Iâm not entirely sure what the number youâd use to determine width by actually translates to in scale. I just threw this together because I couldnât find anything that was accurate enough, and I was just inspired to do it. I think itâs in pixels, but in the scale of the font. So if you upsample it a lot, like I normally do, your width wrapping numbers would be rather high as well.
- Lastly, you can probably make an editor version of this as well, but my concern is that I canât really discern between manual linebreaks and wrapping linebreaks, so I just let it run the one time after I assign the text and leave it at that.
Really like you version with the ability to set an actual width (and see it live in the editor). Works like a charm for me so far.
Thanks rrsimon, this is excellent!
Line 39 â Missing logical operators
I modified the rrsimonâs code to âperfectâ what happens when you change the angling of the parent objects or modify the text. What you do is, attach this script to any cube, and since there is no âFont.textureâ property (unfortunately), you have to put the texture on a separate object and assign that object to textObj.
direction can either be âFrontâ, âRightâ, âBackâ, âLeftâ, âUpâ or âDownâ to tell what side of the cube to put text on. offset tells how far off the cube to put the text and should be a small number. A negative value places the text inside the cube. message tells what message to put on the cube. fontName is where in the Resource folder your font name is. Do not use extensions. shaderName is where in the Resource folder your shader name is. matName is where in the Resource folder your font materialâs name is. characterSize and fontSize controls the numbers in the newly created object called object_name+â_sheetâ's TextMesh. The new object makes itself a child object under the cube with the script attached. The âsheetâ object is what contains the text (written on the cube). MaxWidth (by default) should always be 1, (which is 1 times the size of the cube).
