[Closed] Social Networking Plugin (Facebook and Twitter) live!

@Xanac, you didnt setup your app properly on Twitters website. Refer to the docs (http://prime31.com/unity/docs) paying special attention to the mention of the callback URL.

 

Now it is saying this while debugging in XCode : SendMessage: object SocialNetworkingManager not found!

 

@Xantec, that just means you didn't add the SocialNetworkingManager prefab to your initial scene.

 

What are the reasons for canUserTweet to be false? My app is set to read and right just to let you know.

 

@Xantec, check the docs for the details: http://developer.apple.com/library/...Reference.html#//apple_ref/doc/uid/TP40010943

 

I've got a problem with the SocialNetwork twitter plugin.
It works fine when I login on Android, but not on Iphone.
It says me : "unauthorized application, please use xauth"

How can oauth login work fine on Android, and not on Iphone?

Android :
TwitterAndroid.init(m_twitterKey, m_twitterSecret);
if (!TwitterAndroid.isLoggedIn()) TwitterAndroid.showLoginDialog();
Iphone :
TwitterBinding.init(m_twitterKey, m_twitterSecret);
if (!TwitterBinding.isLoggedIn()) TwitterBinding.login(m_userName, m_userPass);

 

@Risene, you are attempting to use the Xauth login and don't have permission from Twitter to do so. You have to use the Oauth login with the showOauthLoginDialog method

 

The thing is, how can It be that I have the permission via Android, and not IPhone?

...

Ok, I see, I'm using XAuth on Iphone and OAuth on Android, that's it?

 

@Risene, Twitter rejecting Xauth requests a while back and asked that everyone switch over to Oath. The Xauth login is only still in the iOS version for legacy support.

 

Thanks for the info.
Isn't it still needed on Iphone 3G ( opening a web dialog page using showOauthLoginDialog would close the app, wouldn't it? )

 

@Risene, the dialog is shown in the app.

 

I'm using the Social Network plugin and I have a question: I'd like to know if there is any way to obtain the uid of the Facebook user that is currently logged in through the plugin, instead of using a graph or rest call.

Thank you,

Jay_Santos

 

@jay, I believe I already answered you via email but just in case anyone else wants the answer here it is: The only way Facebook has to get the UID of a user is through the Graph API. The plugin exposes the Graph API through the graphRequest method. I believe the "me" path is the one you want but to be sure you will want to consult Facebooks documentation.

 

Hi, I have a problem with

Code (csharp):

1. if (TwitterBinding.isTweetSheetSupported()) { //...do tweet with tweetsheet

Unlike TwitterBinding.canUserTweet, It never seems to return True.

What is the difference between these two? How can I check for the version of iOS on the device from Unity to make sure Tweet Sheet can be used?

 

@recluse, are you using the latest version of the plugin? It works fine for me on all our test devices.

 

I only purchased it a couple of weeks ago, so I don't see how I couldn't be. I'm checking canUserTweet to display the TweetSheet, as isTweetSheetSupported doesn't ever give a positive. How does isTweetSheetSupported work? Is there a way in Unity I can find the iOS version?

 

Hi recluse - yes I experienced this issue too with even quite recent versions of the SocialNetworking plugin. My workaround was to use "userCanTweet" as a check instead, as this checks the user has the latest iOS and has already configured a twitter account with it.

Looking at the Objective-C code though I think the latest SocialNetworking plugin has "isTweetSheetSupported" checking the correct class now so I think downloading updating the plugin (even from just two weeks ago!) may well resolve this.

Finally, check out the following for information on the user's device:
SystemInfo.deviceModel
SystemInfo.operatingSystem
iPhoneSettings.generation

Dan

 

Thanks Dan.

I've got a problem recognizing the user successfully tweeted. This never fires to the debug...

Code (csharp):

1. function twitterPost()
2.     {
3.         Debug.Log( "Successfully posted to Twitter" );
4.         // do other stuff after tweet posted...
5.     }
6.  

I have added the twitterPost event listener, but this function is not getting called by it?

How can I check the user tweeted successfully?

 

Mike would need to clarify, but I believe the twitterPost and twitterPostFailed events are only raised after leveraging the postStatusUpdate method. I don't think there are success or failure events raised when using showTweetComposer - but I may be mistaken!

 

ok, thanks for the info.

Wondering how I tell when the user has posted via TweetSheet? I mean, I have to know when I can take them back to the game ;-)

 

Ah, no need - Unity is paused while the user is composing their tweet (it shows as an overlay). When they have finished (either by posting or cancelling) Unity is un-paused and continues from the next line...

 

if I post a tweet using postStatusUpdate, the tweet text won't be displayed unless I show it myself for the user, right?

I'm considering using iPhoneUtils.isApplicationGenuine to check if my game has been hacked and then covertly tweet "I'm playing a cracked copy of..."

Would be a nice little ploy to uncover people who didn't buy the app legally.

 

Correct - assuming they've already been through the login or showOauthLoginDialog process to sign in and authorise your app at some point, of course...

As to whether silently tweeting such a message would be a wise idea, I'm not so sure - I'd worry too much about false positives!
Perhaps a "I love this game [iTunes link]" tweet as a subtle and less antagonistic alternative instead

As an aside - something that's not immediately apparent from the plugin's documentation is that clients that can take advantage of the iOS 5 tweet sheet composer don't need Twitter inits, logins or authentications from your app at all - the user is tweeting directly from their OS, not from your app (if that makes sense).

 

My game already tweets "I love this game... " and in return the player gets an extra life each time they play.

I figured tweeting a different message if the game had been cracked might wake up those people who don't care or know about indie game devs (and how every single legit download helps me to pay the rent)

Yes, I just noticed as well that using Tweetsheet doesn't need the init, or login - cool.

 

Seems like whatever I try to do afterwards I am getting EXC_BAD_ACCESS

 

@recluse, what steps are you taking to get a bad access? Can you post a stack trace (type "thread apply bt all" in the Xcode console while crashed)?

 

@prime31 just mailed you a screen dump. It's happening in my playerManager start, so probably doing something stupid... If I load the title level after a successful tweet it doesn't crash.

@DarkJedi Tweetsheet doesn't seem to pause for me like you said - my app is already loading the next level even before the tweet has been sent!

EDIT: bollocks, I've found it. Undeclared variable in the inspector in my player manager. Major DOH!

 

Oh, sorry mate - I assumed it worked similarly to the postStatusUpdate method in that respect, but clearly not!

 

@prime31 Facebook login it's working great on an iPhone 4 with the facebook app using single sign on. On an iPhone 3G (without the facebook app installed), it shows the white window with the "x" button, the loading spin.. and then it gives "Facebook login failed", without showing the login form.

----------
[solved]: the old iPhone 3G was with wrong Date.

 

As for the catching pirates topic, I wouldn't suggest advertising that your game has been cracked and is available for free. Although, you could just include some strange string of characters hash-tagged at the end of the tweet. That way you could search twitter, and as long as it's not a common string then you should have a nice list of pirates waiting for you.


Whether you can do anything about them or not is another thing..

 

Hi Prime,

i can not build my app.i have this error : Framework not found Twitter.

SDK : 4.2 (i want to build with 4.2 version)
Unity : last version Pro

Please help.thanks.

 

@Milad, your iOS SDK is out of date. You should be building against iOS 5 which contains the Twitter.framework.

 

FOR EVERYONE THAT HAS ISSUES WITH SCORES (Kev,and others)


I had the same issue after many many days i finally thanks God, i was able to submit a score for facebook leadeboard!.

The thing is that you have to send not the user access token (which is the default send by prime in xcode) but the app access token.

I modify the facebook.m, facebookbinding.cs to avoid that the included access token, replace the token sent as parameter in unity (as kev was doing) and in the binding create an alternate method.

Also it has to use FacebookBinding.loginWithRequestedPermissions(new string[]{"publish_actions, user_games_activity, friends_games_activity"});

Set on de FB dev page, on configuration/advanced: Login to Web and not to Mobile/desktop

Note that the app access token has to be captured in xcode (i don't know how ) but temporally you can use the APPID|APPSECRETID as the token.

I think that is all. If anybody needs some help to get scores or achievements working please tell me.


PD. Prime could you make this stuff well done and send us in the next update please?

 

Hi prime31!

I worry about action of SNS plug-in.

I set an Orientation setup of my application to AutoRotation.
It is Landscape Left/Right which was permitted by this AutoRotation.
I showed as a screen of LandscapeLeft first. Next, the TwitterLogin dialog was shown on the screen.

If a TwitterLogin dialog is closed as it is, a screen will change to LandscapeRight.
In the meantime, I am not rotating that of my iPhone.
It was able to see not only in my application but in the sample code project of plug-in.
And this is not seen by FacebookLogin.
Is there any way I solve this view problem?


used version SocialNetworking_2012-01-28
Unity 3.4.2f3 pro ( with MacOS iOS build )
iOS SDK 5.0
Device iPhone4S (5.0.1)

 

Is there a way to get confirmation that a tweet was successfully posted using TweetSheet?

 

@Masahashi, I cannot reproduce what you are seeing. If you have the Player Settings set to autorotate and the animated checkbox is checked Unity will obey the device orientation. If you change the orientation manually anywhere in code you will break the auto orientation.


@recluse, there is currently no event for closing the Tweet Sheet. The reason we avoided adding it is because it either requires weak linking an entire base library (not a good practice) or requiring iOS 4+. There are still folks who are supporting iOS 3 believe it or not se we didn't yet add the event.

 

ok, I'm using oldskool tweeting now, but I'm not seeing TwitterPost() called in my script after successful posting. I have set up the event listeners in the same script, so shouldn't this function get fired after a post?

Code (csharp):

1. function twitterPost() : void
2.     {
3.         Debug.Log( "Successfully posted to Twitter" );
4.         tweetPosted=true;
5.        
6.     }
7.  

 

@recluse, I don't see you adding the event listener anywhere. See the *EventListener file for examples of how to listen to all the available events.

 

it's added in the same script - I didn't post it all cos its long...

 

full script is:

Code (csharp):

Strangely, after adding a Debug.Log to the SocialNetworkingManager script...

Code (csharp):

1. public void twitterPostSucceeded( string empty )
2.     {
3.         if( twitterPost != null )
4.             twitterPost();
5.             Debug.Log("twitter posted successfully!!!");
6.     }
7.  

my twitterPost function is firing.

 

@recluse, that all looks about right to me. What do you see in the console? Do you have the *Manager prefab in your initial loading scene?

 

Well, it all seems to be working now - I'm getting twitterPost() firing when posting is successful.

I'm also getting failed posts reported too.

One more Q: when i add a URL to my tweet text, i.e http://itunes.com/apps/myappname, it doesn't seem to get turned into a clickable link by Twitter. Am I missing something? I'm sure it worked when I did it via tweetsheet.

 

@recluse, Twitter is supposed to wrap all links in t.co shortened versions. The plugin doesn't do anything special with them.

 

yeah, I realize it's not the plugin end. Just wondering why my http:// isn't getting wrapped.

 

btw, is there a reason you recommend loading the *Manager prefab in the initial scene? I do that with the GameCenter plugin but I am loading the NetworkManager in its own scene (as all tweeting is done in this scene only). Should I load NM in the initial scene too?

 

Hi,

I've been trying to post an image from my Android Phone but nothing works for me right now...

I tried with the postImage and graphRequest function and both of them return me errors. I'm pretty sure my image path is right and my image is not that big (I've seen a limitation of 720px)...

Here is a sample of my code with the postImage function

Code (csharp):

1.  
2. void authDidSucceedEvent()
3. {
4.      Texture2D myTexture = new Texture2D(Screen.width / 2, Screen.height / 2);
5.      myTexture.ReadPixels(new Rect(0, 0, Screen.width, Screen.height), 0, 0);
6.      myTexture.Apply();
7.  
8.      FacebookAndroid.postImage(myTexture.EncodeToPNG(), "test");
9. }
10.  

Error Message : "An unknown error occurred"
Error Code : 1

--------

With the graphRequest function

Code (csharp):

1.  
2. void authDidSucceedEvent()
3. {
4.     Dictionary<string, string> dict = new Dictionary<string, string>();
5.     dict.Add("access_token", FacebookAndroid.getSessionToken());
6.     dict.Add("message", "test message");
7.     dict.Add("picture", "http://www.thomasstockwell.com/wp-content/uploads/2009/01/generic_cola_can_jewel.jpg");
8.     dict.Add("source", "http://www.thomasstockwell.com/wp-content/uploads/2009/01/generic_cola_can_jewel.jpg");
9.     dict.Add("link", "http://www.google");
10.     dict.Add("name", "test");
11.     FacebookAndroid.graphRequest("photos", "POST", dict);
12. }
13.  

Error Message : "(#324) Requires upload file"
Error Type : OAuthException

any help would be appreciated!

Thank You!

 

@pysavard, checkout the demo scene for the details. You can't post PNG's encoded with Unity directly due to a bug with the PNG encoder. You have to use the JPG encoder that is included with the plugin.

 

Doh!! I've forgot the demo scene... thank you for the tips, I'll check that right now...

PY

 

I'm getting this warning suddenly...

Edit: bah, i see what i did!
