Button in scene view

Hi, I;m tryin to make a clickable scene button, but it wont work

Code (csharp):

1.  
2. void OnDrawGizmos () {
3.      Handles.BeginGUI();
4.  
5.      if (GUI.Button(new Rect(10, 10, 100, 50), "Button"))
6.      {
7.        Debug.Log("Pressed");
8.      }
9.    
10.      Handles.EndGUI();
11.    }
12.  

 

Because your trying to call it on draw gizmos

 

Does it show up? Because I think you can only draw Gizmos in the OnDrawGizmos.

 

You need to place the code in a window on your OnSceneGUI function, something like this:

Code (CSharp):

1.  
2.        GUILayout.Window(0, new Rect(10, 10, 100, 100), (id)=> {
3.             GUILayout.Button("A Button");
4.         },

 

I dont need any windows, I just need a scene view button, and yes it draws with OnDrawGizmos...
I've tryied this way:

Code (csharp):

1.  
2. void OnDrawGizmos () {
3.      Handles.BeginGUI();
4.  
5.      Rect rect = new Rect(10, 10, 100, 50);
6.  
7.      GUI.Button(rect, "Button");
8.  
9.      if(Event.current.type == EventType.MouseDown)
10.      {
11.        Debug.Log("press");
12.      }
13.  
14.      Handles.EndGUI();
15.    }
16.  

And it works everywhere except the button's rect... wtf? How can I do the opposite?

I can make this work this way, but without button... looks like button blocking click event...

Code (csharp):

1.  
2. void OnDrawGizmos () {
3.      Handles.BeginGUI();
4.  
5.      Rect rect = new Rect(10, 10, 100, 50);
6.  
7.      if(Event.current.type == EventType.MouseDown && rect.Contains(Event.current.mousePosition))
8.      {
9.        Debug.Log("press");
10.      }
11.  
12.      Handles.EndGUI();
13.    }
14.  

Help, I need this to work with a button, not just with rect!

 

try it on OnSceneGUI () { }
see if that makes a difference. It really hurts my brain that you're doing it in gizmos space ha

 

It wont work inside OnSceneGUI at all ...

 

I just tested in OnSceneGUI and it worked..

 

Exact same code I used. Except I drew a box to visualise it.

 

Might be a stupid question but are you sure you're clicking in the right area?

 

Hey, It works with GUI.Box but not with a Button... Is there a way to draw a GUI.Box like a button, GUIStyle or something?

 

yeah use GUI Style, although I'm curious as to why it's not working for you. Even without a box it works for me. Although I do have other stuff going on.

Try adding SceneView.RepaintAll (); somewhere in your on scene gui function. That's the only thing my brain can think of that might be causing the issue

 

Can you post your version pls?

 

I can't post my whole script, but here's what I used to test your issue:

Code (CSharp):

1.  
2.    void OnSceneGUI () {
3.         Handles.BeginGUI();
4.              
5.         Rect rect = new Rect(10, 10, 100, 50);
6.  
7.         if(Event.current.type == EventType.MouseDown && rect.Contains(Event.current.mousePosition))
8.             Debug.Log("press");
9.      
10.         Handles.EndGUI();
11.  
12.         SceneView.RepaintAll ();
13.     }

 

Just nothing....

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4. using System.Collections;
5.  
6. public class Test : Editor {
7.  
8.    void OnSceneGUI () {
9.      Handles.BeginGUI();
10.    
11.      Rect rect = new Rect(10, 10, 100, 50);
12.      GUI.Box(rect, "Button");
13.      if(Event.current.type == EventType.MouseDown && rect.Contains(Event.current.mousePosition))
14.        Debug.Log("press");
15.    
16.      Handles.EndGUI();
17.    
18.      SceneView.RepaintAll ();
19.    }
20. }
21.  

No box, no click detection...

 

hmm I'm stumped bro. I'm not sure why it's not working for you. It must be something obvious..

You have hooked up the editor script to your base script right? the editor class is in the editor folder?

 

Ok, here is what I have for now:

Script:

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4.  
5. public class testScript : MonoBehaviour {
6.  
7.    public GameObject selected;
8. }
9.  

Editor Script:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4. using System.Collections;
5.  
6. [CustomEditor(typeof(testScript))]
7. public class Test : Editor {
8.  
9.    testScript myScript;
10.  
11.    void OnEnable()
12.    {
13.      myScript = (testScript) target;
14.    }
15.  
16.    void OnSceneGUI () {
17.      Handles.BeginGUI();
18.      
19.      Rect rect = new Rect(10, 10, 100, 50);
20.      GUI.Box(rect, "Button");
21.      if(Event.current.type == EventType.MouseDown && rect.Contains(Event.current.mousePosition))
22.        Selection.activeGameObject = myScript.selected;
23.      Handles.EndGUI();
24.      
25.      SceneView.RepaintAll ();
26.    }
27. }
28.  

The problem is GUI.Box is drawing only if the object with Script is selected(I need it to be drawn allways)... The other problem when I click this box, selection object goes to the myScript.selected gameobject, and immediately goes null.

 

Ok so I've tested this out. And it's working now. The issue was that the event.current wasn't being used. Fixed it with event.current.Use ();

I've cleaned it up a little:

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3. using System.Collections;
4.  
5. [CustomEditor(typeof(testScript))]
6. public class Test : Editor {
7.  
8.     testScript TestScript {
9.         get { return (testScript) target;}
10.     }
11.  
12.     void OnSceneGUI () {
13.         Event e = Event.current;
14.  
15.         Handles.BeginGUI();
16.      
17.         Rect rect = new Rect(10, 10, 100, 50);
18.         GUI.Box(rect, "Button");
19.         if(e.type == EventType.MouseDown && rect.Contains(e.mousePosition)) {
20.             Selection.activeGameObject = TestScript.selected;
21.             Debug.Log("work whore!!");
22.         }
23.  
24.         Handles.EndGUI();
25.  
26.         e.Use ();
27.     }
28. }
29.  

 

It goes null because you're only setting the object when the mouse is down and is within that rect

 

Set it to EventType.MouseUp

 

Maybe the problem is my unity version (4.5.1f3), becouse I got the same problems...
-Click event and box draw works only if testScript gameobject is selected..
-selection.activegameobject goes null after I releasing mouse button...

 

MouseUp wont work at all

 

this isn't a error. This is just how is (I think). You need to lock the inspector for the scene view code to work

 

really?! I think Unity doesn't like you my friend ha. Have you tried right clicking? Because sometimes my mouse (magic mouse) doesn't register left clicks in editor mouse up but does for right click

 

Ok. maybe there is a way to ignore mouseUp or something?

 

Hm.. strange, but mouse up detection almost works now... it works with Debug, but wont work with selection object change...

Code (csharp):

1.  
2. if(current.type == EventType.mouseUp)
3.      {
4.        if(rect.Contains(Event.current.mousePosition))
5.        {
6.          Selection.activeObject = selected;
7.          Debug.Log("Up");
8.        }
9.      }
10.  

"Up" word appears in my console, but selection never changes or assign.. My brains are blown up...

 

any ideas?

 

Have you tried the following?

For anyone who comes across this from google, just wanted to update it.

Code (CSharp):

1. using UnityEngine;
2.  
3. [ExecuteInEditMode]
4. public class testScript : MonoBehaviour
5. {
6.     public GameObject selected;
7. }

Code (CSharp):

1. using UnityEngine;
2. using UnityEditor;
3.  
4. [CustomEditor(typeof(testScript))]
5. public class Test : Editor
6. {
7.     void OnSceneGUI()
8.     {
9.         Handles.BeginGUI();
10.         if (GUI.Button(new Rect(10, 10, 100, 50), "Button"))
11.             Debug.Log("Clicked the button with text");
12.         Handles.EndGUI();
13.     }
14. }

 

To pay it forward, here is the idea, evolved a bit.

The idea is you might want to jump between multiple gameObjects, with a persistent menu.

First, declare a base editor class that each shortcut target can share.

Code (CSharp):

1. public class GameShortcutsEditor : Editor
2.     {
3.         protected void OnSceneGUI()
4.         {
5.             float btnHeight = 50;
6.             float btnPadding = 10;
7.             float btnY = btnPadding;
8.  
9.             Rect GetRect(float y) => new Rect(btnPadding, y, 100, 50);
10.  
11.             void AddBtn(string v, Action pressed)
12.             {
13.                 if (GUI.Button(GetRect(btnY), v))
14.                 {
15.                     pressed();
16.                 }
17.                 btnY += (btnHeight + btnPadding);
18.             }
19.  
20.             Handles.BeginGUI();
21.             AddBtn("Select Foo", () => Select<Foo>());
22.             AddBtn("Select Bar", () => Select<Bar>());
23.             Handles.EndGUI();
24.         }
25.  
26.         private void Select<T>() where T : UnityEngine.Object
27.         {
28.             {
29.                 Selection.activeObject = FindObjectOfType<T>();
30.             }
31.         }
32.     }

^ This just stacks some vertical btns, and when one is clicked, selects a GameObject of some type.

Then, just declare some concrete instances, that call base.OnSceneGui()

Code (CSharp):

1.  [CustomEditor(typeof(Foo))]
2.     public class FooShortcuts : GameShortcutsEditor
3.     {
4.         new private void OnSceneGUI() => base.OnSceneGUI();
5.     }
6.  
7.     [CustomEditor(typeof(Bar))]
8.     public class BarShortcuts : GameShortcutsEditor
9.     {
10.         new private void OnSceneGUI() => base.OnSceneGUI();
11.     }

Getting you this Can switch back and forth, and the menu stays put.

 

work whore!!
