How to make a multi line textfield for editor?

So, I was going through the scripting reference in VS, and I came across textarea in the editor section, and I thought that would be very useful, but as I was trying to write it in C#, I have no clue of how to use it.

 

Bump?

 

If you're talking about displaying a textarea in the Inspector panel for a string variable of your component then you can create a script like this (this script must reside in a folder called "Editor" in your project):

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4.  
5. [CustomEditor(typeof(Test))] // 'Test' here is your component class name
6. public class TestUI : Editor {
7.    
8.     public override void OnInspectorGUI ()
9.     {
10.         Test test = target as Test;
11.         EditorGUILayout.LabelField("My field");
12.         test.myField = EditorGUILayout.TextArea(test.myField);
13.     }
14. }
15.  

If you're talking about using a textarea in the GUI on your game play then take a look at the reference page

 

Can you give a little more info on this? Like, how to set it up properly? Cause I have no clue of how to use this :S

This is the script

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEditor;
4.  
5. [CustomEditor(typeof(Note))]
6. public class Note : MonoBehaviour {
7.        
8.     //The Skin/Background of the GUIStyle
9.      public GUISkin mycustomSkin;
10.     //The Text Of The Note
11.     public string Text = "Insert Your Text Here!";
12.    
13.     void Start () {
14.    
15.         //AutoSet the Name
16.         transform.name = "Note";
17.        
18.         //If there is no collider on the note add one
19.         if (collider == null) {
20.            
21.             Debug.LogError ("No Collider On Note " + name + ". Add A Collider!");
22.            
23.         }
24.        
25.     }
26.  
27.     void OnGUI()
28.     {
29.         Text = EditorGUI.TextArea(new Rect(10, 10, 200, 100), Text);
30.  
31.  
32.     }
33.  
34.  
35.        
36. }
37.

The link has a nice solution, I'll rewrite it here just for people who tend to scroll to the bottom quickly ignoring links:

Add the TextArea attribute to your string field:

Code (CSharp):

1.  
2.     [TextArea(3, 10)]
3.     public string messageText;
4.  

1st param is min number of lines to show, second param is number of lines from which you start showing scrollbar.
See doc on https://docs.unity3d.com/ScriptReference/TextAreaAttribute-ctor.html

I found that the scrollbar appears a little before reaching max number of lines, but anyway.



It also works on Scriptable Objects.
