How to make buttons in scene view?

I want to make buttons on scene view. But i don't find how...
Like this:

 

You should use the method OnSceneGUI of your Editor class, then inside it, you can call the Handles.BeginGUI method and use the GUI.Button method to draw your buttons, and finally call and Handles.EndGUI, as I did here: #unitytips: Sprites Collection.

This is will result in buttons like these on Scene view:

 

This is the button associated with the sprite. But I want to draw buttons on top of "Scene view" like on second screenshots. (Me need buttons for my custom editor, if i click to buttons i take the tool for spawning object).

 

Try this, You will just have a option to enable/disable your toolbar it in Windows Menu.

Code (CSharp):

1. using UnityEditor;
2. using UnityEngine;
3.  
4. public class CustomTools : EditorWindow
5. {
6.     [MenuItem("Window/Custom Tools/Enable")]
7.     public static void Enable()
8.     {
9.         SceneView.duringSceneGui += OnSceneGUI;
10.     }
11.  
12.     [MenuItem("Window/Custom Tools/Disable")]
13.     public static void Disable()
14.     {
15.         SceneView.duringSceneGui -= OnSceneGUI;
16.     }
17.  
18.     private static void OnSceneGUI(SceneView sceneview)
19.     {
20.         Handles.BeginGUI();
21.  
22.         if (GUILayout.Button("Button"))
23.             Debug.Log("Button Clicked");
24.  
25.         Handles.EndGUI();
26.     }
27. }

 

In this video his have custom button look at 10:00 in video, how it's working?:

 

Ok this looks interesting

You need just use [InitializeOnLoad] attribute on a inherited from UnityEngine.Editor class, and in static constructor subscribe on a SceneView.duringSceneGui event.

Some example with a toggle:

Code (CSharp):

1.  
2.     [InitializeOnLoad]
3.     public class PointLabelHandlersEditor : UnityEditor.Editor
4.     {
5.         private static bool _someToggle;
6.  
7.         static PointLabelHandlersEditor()
8.         {
9.             SceneView.duringSceneGui -= OnDuringSceneGui;
10.             SceneView.duringSceneGui += OnDuringSceneGui;
11.         }
12.  
13.         private static void OnDuringSceneGui(SceneView obj)
14.         {
15.             Handles.BeginGUI();
16.             {
17.                 GUILayout.BeginArea(new Rect(10,10, 200, 70));
18.                 {
19.                     _someToggle= GUILayout.Toggle(_someToggle, "Some toggle!");
20.                 }
21.                 GUILayout.EndArea();
22.             }
23.             Handles.EndGUI();
24.      
25.             if (_showLabels)
26.             {
27.                 DoSomeStaff();
28.             }
29.         }
30.     }
