Spiller Library OUYA-backend

ratalaika — Fri, 28 Dec 2012 12:33:42 +0000

Hello, I want to announce that I created a library making 2D games in a easy way some time ago... And today I have started the OUYA backend :D!! I tested it under my Nexus 7 and it seems to work fine, but it still requires tooons of updates hehe

The library is completely free at -> https://github.com/ratalaika/spiller
I would like that someone try it out so we all could improve it, and fix the current bugs, in order to make awesome games for OUYA :)

Regards!

Feature Request: Promo Codes

SpoonThumb — Wed, 09 Jan 2013 11:39:10 +0000

I've been thinking it'd be cool to have promo codes to give out to game reviewers or as prizes for competitions etc. As in be able to just stick an extra int parameter into requestPurchase() to represent a code, and if the code has not been used for that Purchasable before (globally / across all users), the purchase succeeds

Handling controllers with Marmalade SDK

zyndor — Thu, 10 Jan 2013 23:52:35 +0000

Hi All,

I was wondering if anyone had made some headway interfacing the OUYA controllers with the Marmalade SDK.

Naturally, the touchpad (I've only tested this with one controller though) is picked up nicely as an s3e Pointer Touch/Motion event, and the buttonpresses come through as s3e Key events.

However:

- the keycodes I'm getting have nothing to do with the values of the OuyaController constants, although, as you'll see below, the mappings do make sense.

- for the D-pad and the OUYA buttons, TWO events are generated with two keycodes, and these are the same for each controller.

The mappings:

LB (102) -> 74 (s3eKeyLS)
RB (103) -> 75 (s3eKeyRS)

LT (104) -> nothing?

RT (105) -> nothing?

DPAD LEFT (21) -> 9 (s3eKeyLeft) / 206 (s3eKeyAbsLeft)

DPAD UP (19) -> 10 (s3eKeyUp) / 204 (s3eKeyAbsUp)

DPAD RIGHT (22) -> 11 (s3eKeyRight) / 207 (s3eKeyAbsRight)

DPAD DOWN (20) -> 12 (s3eKeyDown) / 205 (s3eKeyAbsDown)

O (96) -> 78 (s3eKeyOk) / 208 (s3eKeyAbsOk)

U (99) -> 89 (s3eKeyButton1) / 203 (s3eKeyAbsGameD)

Y (100) -> 90 (s3eKeyButton2) / 202 (s3eKeyAbsGameC)

A (97) -> 126 (s3eKeyButtonBack) / 210 (s3eKeyAbsBSK - abstract backwards softkey)

The questions:

- Those who tested touch events on multiple controllers - do they come through with different touch ids?

- What's the most obvious way to tell which controller was the source of an event in Marmalade?

- What's the most obvious way to handle the analogue sticks and the two triggers?

(What I'm guessing is, I'm going to have to write my event handling (adding the information from MotionEvent.getDeviceId()) and interface that with JNI - bonus question: is there any way to attach MotionEventListeners to Marmalade's LoaderActivity, or is the only way to use a custom activity?)

Thank you for your input (no pun intended).

Two Quick Questions

KrazyTraynz — Thu, 10 Jan 2013 01:22:44 +0000

Sorry if these questions are stupid, but I just started with OUYA about 10 minutes ago.

1. Do I set games up as Android applications, or is there some sort of special option I should use?

2. Do I have to download the Unity engine separately, or is it included in the ODK?

Thanks :)

Multiple Controllers ~ Who pressed the A Button?

ReaperOfShibuya — Tue, 08 Jan 2013 16:43:14 +0000

I've been looking at the Controller demo project in the ODK and it's very good about illustrating how to work the controller with button presses and joystick movements. What's not as clear is how to tell which controller is doing the press; with all 4 controllers linked, pressing A on any of them will light up the same virtual "A button" on the screen.

In the documentation, there's a way to get a controller object from a player number:

OuyaController c = OuyaController.getControllerByPlayer(playerNum);

There must be a way to do the opposite upon a button press, but the answer is eluding me. Anyone have a solution to this?

GLSurfaceView what format are you using?

hypercanestudios — Thu, 10 Jan 2013 00:15:01 +0000

Hey folks,

I was curious what surface format you are using, RGB565 or RGB888? We've been using 565 to squeeze a few more fps out.

API 14 and API 16

stolk — Wed, 09 Jan 2013 06:46:32 +0000

Hi,

In the setup documentation, it tells you to install both API 14 and API 16.

Why is this?

Further down the page it specifically tells you to build against API 16.

So why install API 14 at all?

Thanks,

Bram

Testing the launcher, Error code 3002 when contacting to servers

pixjuegos — Fri, 28 Dec 2012 12:58:24 +0000

Whenever I run the launcher in my Nexus 7 or click on a sample game I'm testing, it says:
"Error 3002: Error parsing response from server"

This error is probably related to the software being still a beta.

Should I care or do something to solve it?

HOWTO: Running emulator from Eclipse [using Linux]

RogerL — Wed, 09 Jan 2013 22:04:29 +0000

I have updated setup documentation.
But I am not a friend with this formating markup yet...

Note: using forums for bug report / instructions breaks down when used by more than a few people.

Net Framework support

TheUndisputed — Thu, 03 Jan 2013 12:04:50 +0000

Hello i wood like to ask a ? if this is possible
most of you here nows UNITY game engine wicth runs on mono netframework
and there are support for unity

so my ? is this
link to xamarin.
http://xamarin.com/

can the OUYA Team make a deal with xamarin. that the mono framework and there OpenTK GLES Wrapper is installed by default on the OUYA Console , it save us developers around 20 megabytes of space for our game and apps

allso it brings all the futures of the net platform to the console

Visual basic,c#,cli c++,pyton,delphi net,pascal net , and a lot more

to give the developers the freedom to program

i think this cood easy be done, snes there is support for UNITY

hope you can do it, so manny developers can reuse there code and get games and apps fast on this console

allso the mono xna can be ported as well

best regards

Michael Hansen

Android... hiding the system UI and other head-bashing ridiculousness.

Suese — Tue, 01 Jan 2013 20:31:54 +0000

2 Parts, one specific the other more general:

Part 1: Specific
So, why is it that a BARE BONES Android project needs over 100 lines of code just to hide the system UI?!
How come I can't just hide the system UI without having a bulky XML file describing the layout of the screen?
Why do I need to have a text label and a button in order to hide the UI?
I don't need a Rapid UI development tool, can I make a project without the XML, or at least one that is so bare-bones I will never ever ever have to worry about it again?
Is there a better bare-bones project template that isn't 100 lines of code long?

Part 2:
Why does Android/Eclipse/Java suck so bad?
Why on gods green earth did we make this on Android?
AS3 requires 5 lines of code to write a program, Java projects seem to require massive boilerplates with tons of required and cryptically named event handlers and work-around code, does anyone else see what's wrong with this?

After a few delight-less days, I'm having serious reservations about Android, Eclipse and Java: all seem to be huge bulky hunks of junk. Does nobody else feel this way?

Ouya Bindings library for "Mono for Android"

liortal — Fri, 04 Jan 2013 08:58:58 +0000

I have created a bindings library for all Xamarin "Monodroid" users.

The source is available here: https://bitbucket.org/liortal/ouya.bindings

Test and tell me if it works, it builds fine.

Note that 2 types are currently missing:

CancelIgnoringJsonResponseListener
CancelIgnoringOuyaResponseListener

Not sure you'd need access to these in your C# code.

Error when tryign to test on Nexus 7

DeerAndCat — Mon, 07 Jan 2013 21:33:10 +0000

I am trying to test the sample game n Nexus 7, but I keep getting an error from even trying to start the launcher:

01-07 22:26:31.701: D/IAP Client Service(7641): Response body was: {"error, {"code":2007,"message":"Invalid console Uuid was provided"}}

Has anyone got any tips for getting round this?

OS and games clipping off edge of screen?

The_Craig — Tue, 01 Jan 2013 14:06:27 +0000

Can't seem to find a way to resolve this issue, it seems to clip at least an inch or two off the sides and the settings option to adjust for pan&scan doesn't seem to work.

Anybody got any ideas?

ShiVa 3D Game Engine + ODK Integration

Right now, controllers are implemented and purchasing is in the works.

Touchpad get input

Coconuts — Wed, 02 Jan 2013 14:44:25 +0000

Hi , I don't understand how to query touchpad input events. In docs i see that a touchpad is configured to behave as a mouse input , but what does it means? Can i use onTouchEvent in AndroidActivity? Is there a way to access with OuyaController class?

I'm tring to make a libgdx input wrapper but i need this information to make it works well!

Android NDK?

pragmojo — Wed, 02 Jan 2013 23:16:32 +0000

Does anybody know if OUYA is going to support applications developed with the android Native Development Kit or whether we'll have to use Java?

Graphic hardware accelaration + Opengl = crash ?

Gruik — Sun, 06 Jan 2013 22:50:39 +0000

Hi,

After hours of struggling to get a working device configuration, i installed the "game sample" app
But when i start a new game, the emulator crashes or hangs
I realized it doesn't crash if i disable the graphic hadware acceleration ("use host GPU" option) ; although i can't do anything in the game since there is no Ouya controller

I'd like to know if it's a specific issue with this sample or if any opengl app is incompatible with this option (the android sdk says it's not compatible with every application, for instance web browser and web view components, but doesn't say more)

If it's incompatible with opengl, are performances good enough to test a game with the emulator ?

Thanks

I run an intel device + HAXM, under windows 7

Emulator & Controller Setup

Andi_de — Sat, 05 Jan 2013 11:31:39 +0000

Hi all,

I'm struggeling getting an 360 Controller to work with a virtual android device.

Setup according to Ouya-Docs works fine (hence there are some points I cannot find in the definition of the VM - like "d-pad support"), the Ouya Launcher is running, Sample ControllerTest Project compiles and deploys as expected, Picture of Controller is rendered.

But how do I get my PC-enabled xbox 360 Controller to interact with the running VM?

Thanks for any advice,

Andi

Controller 'Disconnected' API

AcnePlay — Fri, 04 Jan 2013 15:41:43 +0000

Is there anyway to know if a controller was connected or disconnected durring runtime? or am i missing something? cant find any clues in the documentation or sample projects in the ODK 0.0.4.

Thanks in advance

NDK working?

Oriku — Fri, 04 Jan 2013 19:37:05 +0000

Has anyone had any success getting a NDK application working?

Game Crashing with "Could not fetch app info"

Amplify91 — Tue, 01 Jan 2013 21:32:35 +0000

I have pushed my Android game onto the OUYA and am trying to launch it on the TV. I have initialized the OuyaFacade, but I am not trying to do anything else with it yet.

public void onCreate(Bundle savedInstanceState) {
OuyaFacade.getInstance().init(this, OUYA_DEV_ID);
super.onCreate(savedInstanceState);

My game seems to not be showing art resources and hanging. Then it will crash and give me this error: Could not fetch app info (errorCode 2005, errorMessage Invalid app Uuid was provided).

Thoughts? Suggestions?

Note: My graphics use OpenGL ES 2.0 and my game uses the LibGDX framework. So I am using the Android backend.

Multiplayer Service with API

JamesS237 — Wed, 02 Jan 2013 04:48:15 +0000

Hello Everyone, I am a server developer, I do everything from apps to websites an games.

One thing I personally hate, is having to create a backend for online multiplayer games.

As developers, who would like access to a service that had the backend pre-built? With a simple API?

I personally do not know how you would like it to be used? Any ideas?

I'm thinking a simple send and receive JSON messages as an option? What are your thoughts, and how would you like this, as developers, to work? (I will open source the code, I don't want to own it, I think it'd be a good community project)

How do you set up the OUYA as an android device in eclipse?

Anticitizen — Fri, 04 Jan 2013 02:57:29 +0000

I am having trouble getting eclipse to discover the OUYA. Does anyone have any tips on how to do this?

I can use any language except Java :x

tommyroyall — Mon, 31 Dec 2012 04:22:27 +0000

Hey guys, sorry for asking such a question, but is there a possibility to use any language except Java? I can code in C or Python, C++ if it comes down to it, and I can code for android, but how would I go about getting the controller to work? Do I need a medium for it that's in Java?

How do you install the sample game/sample app?

Anticitizen — Thu, 03 Jan 2013 04:57:40 +0000

Title says it all. How do I get the sample game from the ODK onto my OUYA? I've plugged the OUYA into my computer and it opened as if it were a USB thumb drive. Am I just supposed to copy the executable into one of these folders? Or is there something else I should be doing?

Accessing The ODK

MayhemSoftworks — Wed, 02 Jan 2013 20:40:07 +0000

My cohorts and I can't seem to figure out how to access the ODK. We have downloaded the zip file, but we can't seem to open it. Any suggestions???

Controller emulation

hotzenplotz — Tue, 01 Jan 2013 14:20:13 +0000

Hi!

Is it possible to somehow emulate the OUYA controller with the keyboard when developing on the Android emulator?

OUYA-ODK Controller Questions

goodhustle — Tue, 01 Jan 2013 21:35:04 +0000

FYI, I'm on Unity and getting started with modifying the provided plugin for real input use of a single controller, but running into problems and now have some questions in general about the controllers in the ODK.

1) Are KeyDown events supposed to be firing repeatedly when a button is held down, or just once in a press/release cycle?

2) Is it unsupported to hold multiple keys down at the same time? Holding two keys down results in repeated KeyDown events for only one of the keys. Releasing that key does not result in repeated KeyDown events for the other key.

3) Is the mSeq private member in KeyEvent an Android standard, or is this an OUYA-specific extension?

4) Can you provide a documentation reference for everyone which states the mKeyCode for each button on the controller? It would be very handy. :)

5) It looks like GenericMotionEvents contain axis data for ALL axes, is that so? And if so, are GenericMotionEvents fired if all axes are at zero?

6) Do controller events work on a polling cycle, and if so what is the polling rate?

Thanks!

Multiplayer support

LeMat — Mon, 31 Dec 2012 22:06:24 +0000

Hello,

Does anyone have any information on what kind of friend-discovery/multiplayer lobby support the OUYA is going to have? I'm not seeing any mention of it in the ODK documentation, and while it's still early, if we need to implement those solutions ourselves, we'll need all the time we can get.
