How to make a line break in a GUI Label

Questions & Answers
1

Hey guys,

I was wondering, is it possible to make a simple line break in a GUI Label?

Because I have a fairly long string that is being written to the screen, and I would rather it to be split to a second line rather than stretch across the whole screen…

Thanks

In java, javascript, C, C++, C#, and similar languages, you need to use an escape character to display certain characters such as new line or have " show up inside a string literal.

They are called escape characters because they “escape” from their normal useage.

All escape characters start with a \ to tell the compiler that the next character should be interpreted differently than normal.

Here are some common ones:

  
	New line
  		Tab
  \v    Vertical Tab
  \b	Backspace
  \r	Carriage return
  \f	Formfeed
  \\	Backslash
  \'	Single quotation mark
  \"	Double quotation mark
  \d	Octal
  \xd	Hexadecimal
  \ud	Unicode character
4

or “line one” + Environment.NewLine + “line two”

If you are not getting what you want with
and want to avoid referencing to System.Environment you can use

e.g. MyText.text = "There will be a carriage return and newline at the end
";

There is another solution for this:
string a = “String you want to get from somewhere with
"
a.Replace(”
", "
");
This way Unity gets "
" as a line break. Not my solution but I can’t remember where I have seen it.

Then new line character is "
".

“line one
line two”

Thanks guys…
Now I don’t have to format my automatically written script.
It’s all done for me.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GetVerticesAndTriangles : MonoBehaviour
{
[SerializeField] private MeshFilter meshFilter;
[SerializeField] private Mesh mesh;
[SerializeField] private Vector3 vertices;
[SerializeField] private int triangles;
public string output;

private void Start()
{
    mesh = GetComponent<MeshFilter>().mesh;

    for (var i = 0; i < mesh.vertices.Length; i++)
    {
        //vertices<em>[0] = vertices_[0] * 2;_</em>

}
vertices = mesh.vertices;
triangles = mesh.triangles;
createOutput();
createOutput2();
updateTheMesh();
}
private void createOutput()
{
output += “using System.Collections;” + "
" + “using System.Collections.Generic;” + "
" + “using UnityEngine;” + "
" + "
";
output += "[RequireComponent(typeof(MeshFilter))] " + "
";
output += “public class MeshGenerator : MonoBehaviour” + "
" +“{” + "
";
output += " " + “Mesh mesh;” + "
" + " " + “Vector3[] vertices;” + "
" + " " + “int[] triangles;” + "
" + "
" + " " + “// Use this for initialization” + "
" + " " + “void Start()” + "
" + " " + “{” + "
" + " " + " " + “mesh = new Mesh();” + "
" + " " + " " + “GetComponent().mesh = mesh;” + "
" + " " + " " + “CreateShape();” + "
" + " " + " " + "UpdateMesh(); " + "
" + " " + “}” + "
";
output += " " + “void CreateShape()” + "
" + " " + “{” + "
";
output += " " + " " + “vertices = new Vector3[]” + "
" + " " + " " + “{”;
for (var i = 0; i < vertices.Length; i++)
{
output += "
" + " " + " " + " " + “new Vector3 (” + ((float)vertices[0]).ToString() + "f, " + ((float)vertices_[1]).ToString() + "f, " + ((float)vertices*[2]).ToString() + “f),”;
//Debug.Log(vertices[0]);
}
output += "
" + " " + " " + “};”;
}
private void createOutput2()
{
output += "
" + " " + " " + “triangles = new int[]” + "
" + " " + " " + “{”;
int lineSep = 0;
for (var i = 0; i < triangles.Length; i++)
{
if (lineSep == 0)
{
output += "
" + " " + " " + " ";
}
lineSep++;
if (lineSep > 2)
{
lineSep = 0;
}
output += triangles + ", ";
}
output += "
" + " " + " " + “};” + "
" + " "+ “}”;
}
private void updateTheMesh()
{
output += "
" + " " + “void UpdateMesh()” + "
" + " " + “{” + "
" + " " + " " + “mesh.Clear();” + "
" + " " + " " + “mesh.vertices = vertices;” + "
" + " " + " " + “mesh.triangles = triangles;” + "
" + " " + “}”;
output += "
" + “}”;
}*_

Ok, i’m trying to load text, stored in public string, to Text on UI.
How should i wrap this text then inputting it in this string from Inspector?
Just adding "
" or "
" doesn’t work for me. It’s just shows text as is.
If i copy text with “enters” from Notepad, it shows only text before first “enter”.
