Check if any button is pressed

Hi

I have a challenge with pressing through buttons and into the gameworld behind the GUI. So I would like to make sure that no buttons are pressed. Both existing buttons and future buttons I might implement. I have several seperate classes working with both OnGUI and CrossPlatformInput

Code (csharp):

1.  
2. //make sure no crossplatform buttons are pressed
3. if(!CrossPlatformInput.GetButtonDown(All buttons)) {
4.  
5.   //make sure no standard buttons are pressed
6.   if(!GUI.Button(All buttons)) {
7.      //here I will do my gameworld input checks.
8.  
9.   }
10. }
11.  

Any light or brainstorming on this topic would be most welcome.

Best regards,
Ithkul

 

So no one has this problem? Or no one knows a solution?

Best regards,

Hm, is it for mobile or desktop?

I think a good starting point would be the TouchInputModule (http://docs.unity3d.com/460/Documentation/Manual/script-TouchInputModule.html, http://docs.unity3d.com/460/Documentation/ScriptReference/EventSystems.TouchInputModule.html). Not quite sure though, I haven't worked a lot with it. I have a similar problem, with GUI elements, behind other GUI elements, that keep being clickable, even though they can't be seen. My solution was to just deactivate the objects, but I guess that is not a possibility in your case.

 

Let me see if I understand you correctly. The game world should only respond to the mouse down event if the user has not clicked a GUI button. The problem is that your game world is responding to every click, even when the user clicks on a GUI button.

Try this:

Code (CSharp):

1. void OnGUI()
2. {
3.     if (GUI.Button(new Rect(20, 20, 200, 40), "Button 1"))
4.     {
5.         Debug.Log("Button MouseDown");
6.     }
7.  
8.     // GUI.Button() "eats" MouseDown and MouseUp events, changing them into Used events.
9.     // So if a GUI button was pressed before this line, Event.current.type will be 'Used'.
10.     // If the mouse did not fall on a GUI button, the Event.current.type will still be 'MouseDown'.
11.     if (Event.current.type == EventType.MouseDown)
12.     {
13.         if (CrossPlatformInput.GetButtonDown("Fire1"))
14.         {
15.             Debug.Log("Fire!");
16.         }
17.     }
18. }

Be careful with this approach because it only works with MouseDown, and totally defeats the purpose of using CrossPlatformInput. You might as well use Input.GetButtonDown().

I really suggest you read the documentation for the Legacy GUI and the new Unity UI.

Legacy GUI (the one you are using): http://docs.unity3d.com/Manual/gui-Basics.html
The new Unity UI: http://docs.unity3d.com/Manual/UISystem.html

Good luck!
