[SOLUTION HERE !!] editor script to select scene objects

Unity Engine
1

At long last!!! Took me too long to figure this out, but this coding is getting easier the more I experiment… practise makes perfect eh ? :wink:

Basically I wanted button in editor window to select objects as I hated having to traverse an expanded Hierarchy list to find main objects. I will try to enhance this by having list of types, like quick picking lights etc…

Heres the code :

class SelectorWindow extends EditorWindow {
var selected: GameObject;
    @MenuItem ("Window/Selector")
    static function ShowWindow () {
        EditorWindow.GetWindow (SelectorWindow);
    }
    function OnGUI () {
		EditorGUILayout.BeginVertical ();
		GUILayout.Label ("Select :", EditorStyles.boldLabel);
		if (GUI.Button (Rect (10,30,100,25), "FPS Controller")) {
		selected = GameObject.Find("First Person Controller"); 
			Selection.activeObject=selected;
		}
			if (GUI.Button (Rect (120,30,100,25), "SkyLight")) {
			selected = GameObject.Find("SkyLight"); 
			Selection.activeObject=selected;
			}
			if (GUI.Button (Rect (230,30,100,25), "Terrain")) {
			selected = GameObject.Find("Terrain"); 
			Selection.activeObject=selected;
			}
			if (GUI.Button (Rect (340,30,100,25), "Deselect All")) {
			Selection.objects = new UnityEngine.Object[0];
			}
		EditorGUILayout.EndVertical ();
    }
}

Let me know on here if you have used this script and found it helpful please… I seem to be the first to post this kind of editor script solution, I couldnt find answers on here at all…

I have’nt tried it yet but was wondering if this works on a tag system? :smile:

Hi Black Mantis, yep it can be done with tags too. Adapted code here :

class SelectorTagsWindow extends EditorWindow {
var selected: GameObject;
var listLights:Array;
    @MenuItem ("Window/SelectorTags")
    static function ShowWindow () {
        EditorWindow.GetWindow (SelectorTagsWindow);
    }
    function OnGUI () {
		EditorGUILayout.BeginVertical ();
		GUILayout.Label ("Select :", EditorStyles.boldLabel);
			if (GUI.Button (Rect (10,30,100,25), "SkyLight")) {
			selected = GameObject.FindWithTag("SkyLightTag"); 
			Selection.activeObject=selected;
			EditorGUIUtility.PingObject(selected);
			}
			EditorGUILayout.EndVertical ();
	}
}

By the way, for people who might not know, the filename has to exactly reflect this part of code:

class SelectorTagsWindow

for this example, the file should be called :
SelectorTagsWindow.js

Also, this script should be placed in “Assets/Editor” folder of your project.

Hey guys, I’m working with editor selection in my script right now too. For the most part I believe I understand it, but I’m getting hung up on NOT having something selected.

Heres what I’m trying to do:

  1. If I have an object selected, display a custom menu that applies to that object (get all the attributes).

  2. If nothing is selected, the custom menu replaces all the values with default values.

I have everything working, except how to check if the selection is null. How can you check if Selection = none?

Good tip; thanks!

Nevermind, I figured out a solution to my problem. Basically I used:

if (Selection.activeGameObject)
{
      GUILayout.Label("SELECTED OBJECT:\t\t"+Selection.activeTransform.name);
}
else
{
      GUILayout.Label("nothing selected . . . ");
}
