Editor Window

In unity one can create custom editor windows. For example to display the AI state of the selected enemy. The window is created by creating a class that inherit from EditorWindow and then put that file in the Assets/Editor directory. To display the window use the MenuItem attribute in the class.

SimpleEdit.cs

This is a minimal editor window that can be opened with the MyEditor/SimpleEdit menutiem. It display the name of the selected object.

using UnityEngine;

using UnityEditor;

public class SimpleEdit : EditorWindow

{

[MenuItem ("MyEditor/SimpleEdit")]

static void Init () {

EditorWindow.GetWindow (typeof (SimpleEdit));

}

private void OnGUI()

{

if (Selection.activeGameObject == null)

{

GUILayout.Label("Selected: No GameObject", EditorStyles.boldLabel);

return;

}

GUILayout.Label("Selected: " + Selection.activeGameObject.name, EditorStyles.boldLabel);

}

void OnInspectorUpdate()

{

Repaint();

}

}
