Hurr? EventType.MouseUp not working on Left Clicks.

Strange problem. Here's my C# code:

Code (csharp):

1.  
2.  
3. Event e = Event.current;
4.                
5. if(e.type == EventType.MouseUp)
6. {
7.     Debug.Log("Mouse Up!");
8. }
9.  
10.  

This works fine when I right click, and middle click, but not when I left click. A "MouseDown" version of this same code works fine for left clicks. any ideas? I am curfused.

If anyone feels like it, can you try out the code on your end and see if you get similar results?

Thanks!

 

Works fine here.

hmm...are you on a pc? I'm on my MBP. maybe that's part of the issue.

Oh! also, I'm using it in an editor script, so that could be something as well.

 

crap, it works fine at runtime. looks like this is an editor problem. probably just have to work around it. :/ Thanks for testing it out.

 

No, I'm on a Mac Pro. It works fine in the editor, using a standard OnGUI function anyway.

Ok, I'be been able to test some of these things to confirm, and it looks like it might be a strange isolated case when using an EditorWindow script with SceneView.OnSceneGUIDelegate. That's the only case where it seems to break, at least so far.

thanks a lot for the help. I'm going to pursue a workaround for now.

 

I will if you provide some code (too lazy to make an editor script just now...).

Same problem here .. did not check on Mac but on Win7 64.

Put code in an editor script ( custom editor script )
and

click holding the shift key

Code (csharp):

1.  
2.  
3.  void StartSelection()
4.     {
5.         print("start selection");
6.     }
7.  
8.     void EndSelection()
9.     {
10.         print("end selection");
11.     }
12.  
13.  
14.     void HandleEvents()
15.     {
16.         Event e = Event.current;
17.         if (e.type == EventType.MouseDown)
18.         {
19.             if (e.shift)
20.             {
21.                 StartSelection();
22.                 e.Use();
23.             }
24.         }
25.         if (e.type == EventType.MouseUp)
26.         {
27.             if (e.shift)
28.             {
29.                 EndSelection();
30.                 e.Use();
31.             }
32.         }
33.     }
34.  
35.   void OnSceneGUI()
36.   {
37.       HandleEvents();
38.   }
39.  
40.  
41.  

I get a 'start selection' but no 'end selection' when using left mouse
I get a 'start selection' and 'end selection' when using right or middle mouse

even more strange ...

After one good click (right or middle) , I get one good click with the left mouse button
before it falls back to the failing behaviour.

Right button to multi - select control points in my spline for now......

UPDATE
-----------

More people experience the same problem

Hinted is to set some editor setting to .. none , so default move/rotate/scale tool does not capture this mouseUp event...

anyone knows what setting this would be?

 

Found the setting that should do the trick, according to the suggestion in my previous posted link,
but it did not work.

setting

Code (csharp):

1.  
2. Tools.current = Tool.None;
3.  

Does not stop the 'mysterious' object from consuming my MouseUp event.

 

Did anyone find a fix for this, I to can get no mouseUp event in my OnSceneGUI(). Is there a workaround for this?

 

Is this related to the problem?

Thank you so much for finding that MADmarine (Thanks to dagbud for the linked post!) It solved the problem I had been struggling with for a couple of nights. Now my tool allows me to populate waypoints in the scene quickly and efficiently and the editor isn't trying to use my input at the same time.

 

Code (csharp):

1.  
2. void OnSceneGUI(){
3.        Event e = Event.current;
4.  
5.         var controlID = GUIUtility.GetControlID(FocusType.Passive);
6.         var eventType = e.GetTypeForControl(controlID);
7.         if (eventType == EventType.MouseUp)
8.         {
9.             Debug.Log("Mouse Up!");
10.             GUIUtility.hotControl = controlID;
11.             e.Use();
12.         }
13.         else if (eventType == EventType.MouseDrag)
14.         {
15.             Debug.Log("Mouse Drag!");
16.             e.Use();
17.         }
18.         else if (eventType == EventType.MouseDown)
19.         {
20.             Debug.Log("Mouse Down!");
21.             GUIUtility.hotControl = 0;
22.             e.Use();
23.         }
24.  
25.  

 

This tutorial made my day!
It explains how to get the different Eventtypes work without losing the focus after clicking on the scene!

 

For some reason (which I don't fully understand) the only thing that helped me was adding this line in the beginning of the OnSceneGui method:

Code (CSharp):

1. HandleUtility.AddDefaultControl(GUIUtility.GetControlID(FocusType.Passive))

 

Adding the line posted by Amitloaf above indeed helped! Now I can register mouse up in my OnSceneGUI! Thanks a lot!
