OUYA Controller Library?

Hot Dog Hero · Jun 23, 2013

I would like to access the OUYA Controller from within Basic4Android.

Button presses should work. However, it doesn't appear that there is a mechanism for getting the left and right stick axis values. According to the OUYA docs, you need to override the activity's onGenericMotionEvent method.

Any suggestions...

You would need to write a library

Erel · Jun 24, 2013

Please try the attached library. I currently don't have an OUYA console so I cannot test it.

You should add a reference to ouya library and write this code:

B4X:

Sub Globals
   Dim ou As Ouya
End Sub

Sub Activity_Create(FirstTime As Boolean)
   ou.Initialize("ou")
End Sub

Sub ou_GenericMotion (Event As MotionEvent)
   Log(Event)
End Sub

Check the logs whether there are any messages printed.

You will also need to copy ouya-sdk.jar from the libs folder into the additional libraries folder.

Note that the library source code is attached. You can compile it with SLC tool.

Will do. Thanks for your help.

I copied the jar and xml files to the Additional Libraries folder for B4A.
I also copied the ouya-odk.jar there.

I followed the posted suggestions for transferring the apk to the Ouya.
http://www.b4x.com/forum/basic4android-getting-started-tutorials/29881-ouya-specific-tweaks.html#post173560

I'm not connected to the Ouya by USB, so I modified your program slightly.

B4X:

Sub Globals
   'These global variables will be redeclared each time the activity is created.
   'These variables can only be accessed from this module.
   Dim ou As Ouya
   Dim Label1 As Label
End Sub

Sub Activity_Create(FirstTime As Boolean)
   'Do not forget to load the layout file created with the visual designer. For example:
   'Activity.LoadLayout("Layout1")
   Activity.LoadLayout("main")
   ou.Initialize("ou")
   Label1.Text = "I'm waiting..."
End Sub

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
   If KeyCode = 96 Then
     Label1.Text = Label1.Text & "O key pressed" & CRLF
    End If
   Return True
End Sub

Sub ou_OnGenericMotion(Event As MotionEvent)
   Label1.Text = Label1.Text & Event & CRLF
End Sub

I can capture key presses but I still can't capture the joysticks.

Suggestions?

Hi Guys, it's been a while since this thread was last updated . Im just wondering if anyone has managed to get the analogue sticks
working yet ? .I've tried Erels code and the code above with no luck. Also is there a KeyReleased event associated with the controller.

Thanks

bump: Also too wondering if anyone has the Analog sticks working...

Erel,

the Ouya Library works great with GOOGLE GLASS

look the log when touch the glasses

(MotionEvent) MotionEvent { action=ACTION_DOWN, id[0]=0, x[0]=648.0, y[0]=74.0, toolType[0]=TOOL_TYPE_FINGER, buttonState=0, metaState=0, flags=0x0, edgeFlags=0x0, pointerCount=1, historySize=0, eventTime=4343781, downTime=4343781, deviceId=1, source=0x100008 }

(MotionEvent) MotionEvent { action=ACTION_UP, id[0]=0, x[0]=400.0, y[0]=114.0, toolType[0]=TOOL_TYPE_FINGER, buttonState=0, metaState=0, flags=0x0, edgeFlags=0x0, pointerCount=1, historySize=0, eventTime=4344949, downTime=4343781, deviceId=1, source=0x100008 }

(MotionEvent) MotionEvent { action=ACTION_MOVE, id[0]=0, x[0]=658.0, y[0]=75.0, toolType[0]=TOOL_TYPE_FINGER, buttonState=0, metaState=0, flags=0x0, edgeFlags=0x0, pointerCount=1, historySize=1, eventTime=4343799, downTime=4343781, deviceId=1, source=0x100008 }

Erel,

2 Questions:

FIRST
====

In your example NOT WORK while not pass in this event:

Sub Activity_KeyPress (KeyCode As Int) As Boolean
ListView1.AddSingleLine (KeyCode)
End Sub

I mean, when you not invoke a activity (I think) its not work, after you touch, pass normally in ou_OnGenericMotion event.

You know any solution to work this only using the touch?

SECOND
=====

In EVENT (return of GenericMotion) Sub ou_GenericMotion (Event As MotionEvent)

I can get this, for example:
(MotionEvent) MotionEvent { action=ACTION_MOVE, id[0]=0, x[0]=491.0, y[0]=107.0, toolType[0]=TOOL_TYPE_FINGER, buttonState=0, metaState=0, flags=0x0, edgeFlags=0x0, pointerCount=1, historySize=0, eventTime=9158211, downTime=9158106, deviceId=1, source=0x100008 }

So, Can I way to get each separete part? Or only the ACTION?

I´m convert to string and then parsing string... Is too ugly
Dim strME As String = Event

Thank You

Not sure that I understand the first question.

About the second:
You can call MotionEvent.GetAxisValue with the axis index as a parameter.

You can get the other values with JavaObject.

B4X:

Dim jo As JavaObject = Event
Log(jo.RunMethod("getDownTime", null))

The methods are listed here: http://developer.android.com/reference/android/view/MotionEvent.html

Alberto Iglesias · Apr 22, 2014

Look this example (attachment), If I start the app and ONLY move the fingers WITHOUT press any button, not fire the GENERICMOTION

But If I touch and put the code in a listview for example, the GENERICMOTION starting work.... Strange!!!

Perfect!

Dim jo As JavaObject = Event
Log("JAVAOBJECT = " & jo.RunMethod("getAction", Null))
'1 = Down, 2 = Move , 0 = Up

Why can't you use Activity_Touch event?

Alberto Iglesias · Apr 23, 2014

I did not know this event. I will try in Google Glasse when return to my house today and I tell you if works or no.

Thanks.....

Alberto Iglesias · Apr 23, 2014

Erel, I try now and NOT WORK with Activity Touch... Only with OUYA Library....

Alberto Iglesias · Apr 23, 2014

Erel, I resolve with this code, look:

In OUYA Event I get the values, Action and coordinates

Sub ou_GenericMotion (Event AsMotionEvent)
Dim jo As JavaObject = Event
Dim iAction As Int = jo.RunMethod("getAction", Null))
Dim iX As Int = event.GetAxisValue(0)
Dim iY As Int = event.GetAxisValue(1)
Activity_Touch (iAction, iX, iY) <------------ Look
End Sub

And In Activity_Touch I get this values to calculate RIGHT or LEFT direction of Google Glass

Sub Activity_Touch (Action As Int, x As Float, Y As Float)
Dim iHorizontal As Int = x
Dim strDirecao As String = ""

Select Action
Case Activity.ACTION_DOWN
lblTouch.Text = "DOWN " & Action & " / " & x & " / " & Y

gDPADXInicio = iHorizontal
gDPADXFim = 0

Case Activity.ACTION_MOVE
lblTouch.Text = "MOVE " & Action & " / " & x & " / " & Y
gDPADXFim = iHorizontal

Case Activity.ACTION_UP

Dim iPoints As Int = (gDPADXFim-gDPADXInicio)
If iPoints < 0 Then iPoints = iPoints * -1
strDirecao = " [" & iPoints & " points]"

If gDPADXInicio > gDPADXFim AND iPoints > gDistancia Then strDirecao = "<===" & (gDPADXInicio-gDPADXFim)
If gDPADXInicio < gDPADXFim AND iPoints > gDistancia Then strDirecao = "===>" & (gDPADXFim-gDPADXInicio)

lblTouch.Text = "UP " & Action & " / " & x & " / " & Y & " : " & strDirecao

Case Else
lblTouch.Text = "XXXX " & Action & " / " & x & " / " & Y
End Select

End Sub

Bu the ONLY problem now is while not pass in this line, the ou_GenericMotion not work... WHYYYYYYYYYYYYYYY?????? :-(
Sub Activity_KeyPress(KeyCode AsInt) AsBoolean

ListView1.AddSingleLine (KeyCode) <=== START the GenericMotion Event
Label1.text = Keycode <=== IF I change and put only this line, NOT START GenericMotion Event

End Sub

Curious not?

Questions:
* What´s the difference the ListView and Label in this situation?
* Why not automatically start without pass in this event first?

Another Problem:

After starting GenericMotion Event, the Activity_KeyPress STOP working

Please use [ code ] [ /code ] tags (without spaces) when posting code.

I don't see how these lines are related. However it is hard to say without a working device.

Alberto Iglesias · Apr 24, 2014

Erel,

The code is in the attachment sample, is more easy read in there.

I don't understand why only after pass through keypress (and put any value in listview), start event GenericMotion

Alberto Iglesias · Apr 24, 2014

Erel,

Look in https://developers.google.com/glass...google/android/glass/touchpad/GestureDetector

I think "public boolean onMotionEvent(MotionEvent event)" is the same like OUYA, no? What can be difference?

Only left this for my project work... :-(

Erel · Apr 24, 2014

It is a different API. Though it shouldn't be difficult to wrap it.
