How can I change GUILayout.Label position and font color in Inspector ?

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using UnityEditor;
5.  
6. [CustomEditor(typeof(GameObjectInfo))]
7. public class GameObjectInfoButton : Editor
8. {
9.    public override void OnInspectorGUI()
10.    {
11.        DrawDefaultInspector();
12.  
13.        GameObjectInfo myScript = (GameObjectInfo)target;
14.  
15.        if (myScript.objectsinfo.Length == 0)
16.        {
17.            //GUI.Label(new Rect(0, 10, 10, 10), "No Results");
18.            GUILayout.Label("No Results");
19.        }
20.        else
21.        {
22.            GUILayout.Label("Found Results");
23.        }
24.    }
25. }
26.  

GUI.Label have a Rect position parameter but it's never show in the Inspector. GUILayout does show in the Inspector but I want it to be in the center and with a bit space from the rest and to change the font colors. "No Results" in red and "Found Results" in black.

 

I believe that your call to GUI.Label actually is showing something in the Inspector, but not where you expect it. Those x and y coordinates (0 and 10 in Line 17) are with respect to the upper left corner of the entire Inspector window, now just the part dedicated to your GameObjectInfoButton. When I run your original code (with Line 17 not a comment), I can see the beginning of a letter "N" in the upper left of the Inspector window. The rest of your label is being overwritten by other graphics in the window.

 

Try this and see if it gives you any ideas on how to do what you want:

Code (CSharp):

1. using UnityEditor;
2. using UnityEngine;
3.  
4. [CustomEditor(typeof(GameObjectInfo))]
5. public class GameObjectInfoButton : Editor
6. {
7.     public override void OnInspectorGUI()
8.     {
9.         DrawDefaultInspector();
10.  
11.         Rect rect = EditorGUILayout.GetControlRect(false, 200f);
12.  
13.         Rect buttonRect = new Rect(
14.             rect.x + rect.width / 4,
15.             rect.y + rect.height / 4,
16.             rect.width / 2,
17.             rect.height / 2);
18.  
19.         GUI.Button(buttonRect, "Centered");
20.     }
21. }
