Make a text area.

This works just like @@GUILayout.TextArea@@ with proper responsiveness to actions like Select all, Copy, Paste in the Editor.
For Undo support, see Undo.RecordObject.
To make the text wrap, set EditorStyles.textField.wordWrap.

Quick script editor.

// Simple script that lets you visualize your scripts in an editor window
// This can be expanded to save your scripts also in the editor window.

using UnityEngine; using UnityEditor;

public class TextAreaExample : EditorWindow { string text = "Nothing Opened..."; TextAsset txtAsset; Vector2 scroll;

[MenuItem("Examples/TextArea usage")] static void Init() { TextAreaExample window = (TextAreaExample)GetWindow(typeof(TextAreaExample), true, "EditorGUILayout.TextArea"); window.Show(); }

Object source;

void OnGUI() { source = EditorGUILayout.ObjectField(source, typeof(Object), true); TextAsset newTxtAsset = (TextAsset)source;

if (newTxtAsset != txtAsset) ReadTextAsset(newTxtAsset);

scroll = EditorGUILayout.BeginScrollView(scroll, GUILayout.Height(position.height - 30)); text = EditorGUILayout.TextArea(text); EditorGUILayout.EndScrollView(); }

void ReadTextAsset(TextAsset txt) { text = txt.text; txtAsset = txt; } }
