Accessing the user name?

Zigbigidorlu — Sun, 03 Feb 2013 12:18:34 +0000

I know we already have access to user's UUID, which, as far as I can tell, is a alphanumeric unique identifier; However, this isn't ideal for leaderboard development.

Is there a way to access the user name instead?

Payment: Receiving receipts problem

Intermediaware — Tue, 12 Mar 2013 05:20:41 +0000

I'm getting the following exception:

java.lang.RuntimeException: javax.crypto.BadPaddingException: unknown block type

in the line:

receipts = helper.decryptReceiptResponse(response, mPublicKey);

The mPublicKey is successfully generated and set. Do you have any ideas or tips where I can start to overcome this issue?

OUYA + Linux Ubuntu/Mint Setup Issue

mscythe — Mon, 11 Mar 2013 20:37:51 +0000

Hi everyone,

I'm using Linux Mint 13 and trying to setup OUYA environment in Eclipse I created the device, but when I start the emulator I get the alert "Can't play this video."

If I press ok, in the next window show the controllers without the background (no problem) and I get another alert "No bluetooth suport!" than nothing happends. I expected to see the "User account window".

Any tips?

Help ouya! fetchGamerUUID problems with on-screen-keyboard

Oriku — Mon, 11 Mar 2013 06:36:51 +0000

So, you may know of Ouya keyboard problems with native activities, where you can call showSoftInput and the keyboard never shows up. Well, I just tried copied fetchGamerUUID from the IAP sample, called it from the game. When I call fetchGamerUUID, it brought up a system dialog asking for a username and password... well guess what. The keyboard never shows up there either when selecting a text box for entry. This means that when I do IAP next week some time I will also be likely blocked at selling things as nobody will be able to enter text either.

Obviously, since this is not my code I can't be screwing this up. Right? I mean, it takes over my screen and input and I don't even see my App anymore. Certainly the code directly from the sample app isn't broken.

Need help from Ouya. This is kind of important. =/

Linking to the OUYA Developer Page from within your game?

Intermediaware — Sun, 10 Mar 2013 23:07:51 +0000

Hi,

is it possible to link to the developer page from within the game.

I have an "More Games" Button inside my apps. On iTunes, GooglePlay and Amazon I can open an URL that links to my developer page.

Is something like this possibile with the OUYA Store?

Text Input with libGdx

Clowen — Sun, 10 Mar 2013 02:46:20 +0000

I'm working on a menu system with libGdx and I'm not sure how to handle Text Input. I was planning to manage simple buttons like normal drawable sprites, but I'm not sure how to handle text boxes. Obviously any text box needs to bring up the soft keyboard, but I'm not sure how to trigger it and how to respond to the input.

Is there anything in libGdx or ODK that makes this easier? How can I go about getting text input within my libGdx game? Thanks.

Multiple Entitlement Purchases

hypercanestudios — Mon, 11 Mar 2013 02:35:48 +0000

Is the purchase server going to prevent duplicate entitlement purchases? From my understanding, these are things that should only be purchased once. Right now I can purchase multiples.

I am gating this in my app, but can foresee some fringe cases involving app re-installs and bad internet connection that could make this difficult to prevent in all cases.

OUYA and C#. How to get started?

dmb21 — Mon, 04 Mar 2013 04:05:39 +0000

I'm an experienced windows developer (Visual Studio C++/C#/OpenGL/DirectX) and would like to give OUYA development a shot in C#. What library/tool options are available? Are there any good resources for getting started or sample apps (spinning box OpenGL type thing)? I realize Unity would probably be the easiest way to get started, but the fewer frameworks/abstractions I need to go through the better.

Exception when calling OuyaController.getControllerByPlayerId before first axis event

goodhustle — Thu, 07 Feb 2013 01:36:11 +0000

Just sent this in as a bug, but I wanted to post in the forums to save people some headache as well. It seems like there's a NullPointerException in this method, so for now you might want to wrap calls to OuyaController.getControllerByPlayerId with try/catch blocks until it gets resolved.

Setting up the Ouya ODK

Hi. Im a C++/C# developer but I also know some Java and Python. I need some info about how to get started using the ODK, as I cant find this information anywhere:

Can I develop games on Windows 8?

What programming languages are supported and which is the best to use with the ODK?

Thanks in advance. : )

Android Development and Emulators - another option: bluestacks

JSIDD — Thu, 07 Mar 2013 15:43:52 +0000

Bluestacks is a software which let you use/run your favorite Android apps on your pc/mac. It also lets you deploy your own developed apps to the bluestacks virtual machine. This is a pretty good option if you are not concerned about the exact specs of the emulator used.

All versions are currently free.

What is the simplest way to check if device is running OUYA framework?

paulscode — Tue, 29 Jan 2013 14:54:56 +0000

Is there a simple way (from the code) to detect if an app is running on a device with the OUYA framework?

I am developing a couple of apps which have special interfaces, graphics, and default preferences when they are running on the OUYA vs. other Android devices.

I am currently checking the value of "hardware" in proc/cpuinfo, which is effective at determining when the app is running on an actual OUYA. However, this method does not cover other devices (like the Nexus 7 for example) which have been set up to run the OUYA framework, or potentially modified kernels for which this string was changed, or even next-gen OUYA releases (a guy can dream!)

Payment Functions

jtn0514 — Thu, 07 Mar 2013 05:16:46 +0000

Anyone else have their payment functions stop working since the new update? I know they just turned out payment encryption so im assuming this is the cause? Anyone else have similar situation?

Joystick controllers in odk-0.0.6 (Java)

pluspingya — Sat, 23 Feb 2013 10:39:45 +0000

Hi all,

I am now trying to get joystick work with Android using ouya sdk.

I tried ouya-controller-testapp from samples in odk0.0.6

I plugged my random twin joysticks (not xbox360 nor ps3) to pc and run an app to my android devices.

There was just a picture of ouya joystick appeared on screen, but cannot see any reaction between app and joystick on my hands.

My joystick works with any games on my PC also some xbox360controller tester tool proved that this should work.

I wonder that how are you guys connecting joystick to android, though pc or directly to devices?

Can someone help me please?

Another question, I followed this docs https://devs.ouya.tv/developers/docs/controllers ;

but why OuyaController.init(this); is undefined?

Sorry if these are noob questions, but I already did searching, but none were found.

Player -> Controller Mapping

badlogic — Sun, 13 Jan 2013 22:47:12 +0000

Hi,

i wanted to poll the guys responsible for the controller API on how they are planning to solve the player -> controller mapping. As i see it, the ODK currently assigns those based on which controller was interacted with first (decompiled the ODK jars, is there an official source repo?).

That's not a bad solution to initiate the mapping. However, as soon as a controller disconnects and reconnects, there doesn't appear to be any way using default Android APIs (InputManager) to reestablished that the reconnected controller represents the original player. This situation gets more complicated with more controllers.

A unique controller ID would help, but that doesn't seem to be available. InputDevice#getId is not unique, it's actually incremental. InputDevice#getDescriptor is meant to be a unique id but fails in reality, as the descriptor reported by each Ouya controller is the same.

I might overlook something, but it seems that the player number functionality of the API can't actually be implemented in any way. I guess a solution to this problem would benefit not only folks using the ODK Java API, but also the Unity side of things. The solution we propose to our users is to use the initial mapping, then listen for disconnects, and ask the user to plug in the controller of the disconnected player, listening for the first connection event in that case.

The current ODK API suggests that the outlined solution is not necessary as the ODK will take care of it. If it can't, then devs might have to restructure their code considerably (adding new UI instead of reyling on the mapping to work in all circumstances).

Thoughts?

IAP interface disappears

oddeven — Sat, 02 Mar 2013 00:30:35 +0000

Hi all, I'm using ODK 0.0.6 with Unity. I just noticed that the IAP interface disappears after ~35 seconds of inactivity. The screen goes completely black until some input is provided. It looks like a 'sleep' mode of some sort.

getPlayerNumByDeviceId() can return -1 after controllers disconnect and reconnect

GnomicStudios — Fri, 01 Mar 2013 04:23:19 +0000

Once a game is running, if a controller (Xbox 360 or Ouya) is connected it gets a new device Id assigned. This new device Id gets mapped to the next available player number. The problem is that when a controller is disconnected, it's mapped player number is never released. When it gets reconnected it always gives a new player number and when this goes over 3, it returns -1.

The ODK needs to detect disconnected controllers and allow the player numbers to be reused. Ideally it would map the same player number to the same reconnected controller.

How will you mitigate piracy in your game?

nimble_gorilla — Wed, 27 Feb 2013 20:55:48 +0000

I want to run a server for my game to provide multiplayer access to players. Players will be able to connect to this server via my Ouya game.

Ouya's purchase system doesn't seem to have any way for my server to reliably verify that someone has a legit copy of my game. Here are some links to Apple's solution:

http://developer.apple.com/library/ios/#documentation/NetworkingInternet/Conceptual/StoreKitGuide/VerifyingStoreReceipts/VerifyingStoreReceipts.html

http://developer.apple.com/library/ios/#releasenotes/StoreKit/IAP_ReceiptValidation/index.html#//apple_ref/doc/uid/TP40012484

Piracy is rampant on Android and iOS. Given Ouya's intended open nature I don't see how there won't be similar problems. Any data sent from a player's device must be considered cracked. When I read articles like this one it makes me nervous:

http://penny-arcade.com/report/editorial-article/when-pirates-outnumber-paying-customers-10-to-1-games-die-very-quickly

I don't want to devote 90% of my server resources to people without a legitimate purchase.

The console already makes some sort of API request with the userID and gameID to return receiptIDs. Why can't the API be opened up to take a gameID and receiptID and return yes/no that it was a valid receipt?

This seems like an "easy" feature to add and is actually something that will generate money for Ouya and developers.

What does everyone else think? Do you have any plans or workarounds to handle these issues?

Getting started

Jepix — Wed, 27 Feb 2013 00:06:20 +0000

I downloaded ODK today. I need to know what to do next,Do i need a certain program to start making the game on the computer. IE: Eclipse. And if I get Eclipse,which should I get?

IAP

stolk — Mon, 25 Feb 2013 07:06:05 +0000

From the 0.06 IAP example code:

receipts = helper.decryptReceiptResponse(receiptResponse, APPLICATION_KEY);

The docs are old though, and describe 0.05 ODK:

receipts = helper.decryptReceiptResponse(receiptResponse);

And they mention:

In the future, we will encourage developers to avoid using the decryptReceiptResponse method.

My questions:

When is the final iteration for IAP framework expected?

It's cutting too close to launch date.

Where can I find my application key?

consoleId?

Zigbigidorlu — Sat, 09 Feb 2013 13:36:04 +0000

I'm looking at the UserManager.requestUsername() method, and I'm noticing a java.lang.String consoleId required.

I've sorted through the sdk documentation, but I don't see where I can find this anywhere to use. What do I need to call to get this string? Or is it developer's choice?

Compatible with a java game engine?

Philip_Smyth — Sat, 12 Jan 2013 01:21:07 +0000

Hello everyone,

I am a student and I am working on creating my first game. The engine that I am using is called J Monkey and is a java based engine. This allows android applications to be created from the code written. However I am unsure how this might effect my desire to release it onto the Ouya console. I would like to believe that it might be generated as an Android application and then transferred over to Ouya, however I do not know if this can be done.

If anyone can help me by clarifying this issue it would be greatly appreciated.

Thank you for your time and have a nice day

What are the dimensions for your game's icon?

Dreamwriter — Sat, 29 Dec 2012 00:56:46 +0000

The icon seems to have an aspect ratio close to 16:9, but I can't tell exactly how many pixels to make it.

720P resolution

Wilds — Sun, 24 Feb 2013 16:39:25 +0000

I have tried several EGL things but to no avail.

Gamemaker and Ouya IAP

jtn0514 — Tue, 05 Feb 2013 00:36:50 +0000

Hey guys, ive been able to get gamemaker to work with the OUYA and launch some apps and use about 60 percent of the ouya controller.

What im mainly stuck on however is the in app payment system with ouya and being able to integrate such a thing into gamemaker so that i can add the option to allow purchasing a full version of the game.

Game-maker studio has a built in function to purcahse from the google play store and requests product id and server to connect to and whatnot, but im curious if the ouya payment server is going to be setup very similar to the google play store in terms of the payment process and transacations?

Im hoping to basically be able to input the ouya payment server and give it a product id and whatnot to allow a transfer /payment just like the google play store does.

I doubt anyone has any experience with this specific instance, but i figured its worth asking atleast...

C# bindings for ODK 0.0.6 now available

KonajuGames — Thu, 14 Feb 2013 15:33:35 +0000

https://github.com/slygamer/ouya-csharp

This is a basic update primarily to get the changed intents.

Further updates will be coming soon where the various listeners will be C#-ified.

MonoGame is undergoing a branch re-org at the moment, so the updated OUYA support in MonoGame will be delayed a bit.
