Hi!
I am integrating OpenFeint to my game and i was wondering if anyone has tried to customize the notifications so they appear as cocos2d elements.

According to their instructions:

OFNotificationDelegate

Developers that wish to disable or customize notification pop-ups must supply an OFNotificationDelegate object during OpenFeint initialization.

- (BOOL)isOpenFeintNotificationAllowed:(OFNotificationData*)notificationData;

This method will be invoked when a pop-up needs to know if it should display or not. Developers can return YES to allow the notification, or NO to disallow it.

- (void)handleDisallowedNotification:(OFNotificationData*)notificationData;

This method will be invoked when isOpenFeintNotificationAllowed returns NO. We recommend developers display a custom notification here using the data provided in the OFNotificationData object. Please see the section on OFNotificationData below for more information.

- (void)notificationWillShow:(OFNotificationData*)notificationData;

This method will be invoked when a default OpenFeint notification is about to be displayed.

So, what i understand is that i must have a

- (BOOL)isOpenFeintNotificationAllowed:(OFNotificationData*)notificationData
{
return NO;
}

- (void)handleDisallowedNotification:(OFNotificationData*)notificationData
{
//Create cocos2d sprite for the background of the notification, its text, someaction to fade it in and out... ??
}

Also it says: Developers that wish to disable or customize notification pop-ups must supply an OFNotificationDelegate object during OpenFeint initialization.
How would i do that?

Thanks!

In your applicationDidFinishLaunching method you should already be calling (assuming you already have OF integrated):

[OFDelegatesContainer containerWithOpenFeintDelegate:self andChallengeDelegate:nil andNotificationDelegate:self];

The third parameter is the notification delegate. In this case my app delegate is also the notification delegate. It will need to implement the OFNotificationDelegate protocol.

In your isOpenFeintNotificationAllowed method return NO for any notifications you would like to create custom notifications for. Likewise, return YES for any that you would like OF to use standard notifications for. The OFNotificationData instance has some properties for determining the type of the notification.

handleDisallowedNotification will get called for any notification in which your isOpenFeintNotificationAllowed method returned NO. You can then inspect the OFNotificationData instance and show the notification however you like (or choose not to show it at all). In a couple of scenarios the OFNotificationData instance can be cast down to get more specific information (such a achievement names and icons).

Take a look here for some more details: http://help.openfeint.com/faqs/api-features/notification-pop-ups

For my game I just create a CocosNode instance with a label for the notification text and a Sprite for the icon. I chose not to make them clickable since it tends to interrupt the game play.

Thanks SmallMike!

One more question :)

For my game I just create a CocosNode instance with a label for the notification text and a Sprite for the icon.

How do you handle it?

I have the notificationdelegate be my appdelegate so i have in my appdelegate:
```
- (void)handleDisallowedNotification:(OFNotificationData*)notificationData
{
	NSLog(@"%@",notificationData.notificationText);
}
```
Now.. i would have there an sprite and label and add it to the layer, but what layer? How would you get the layer that you want to add the label and sprite to?
Or how else do you do it?

Thanks!

Well I have a Notification class that subclasses CocosNode. It has an init method which takes in a Sprite (for the icon) and the message text. The sprite and a label with the message are added to self in the init method.

That, of course, doesn't answer the question of where to add that instance. You can use [[Director sharedDirector] runningScene] to get the current scene, which you can add your Notification node to. You probably want to add it with a high z-index so that any nodes added after will not obstruct it.

There are a lot of little details to work out, such as actually animating the notification in/out and making sure it stays displayed if a scene changes. I'd be willing to post the code for the Notification class, but I'd want to clean it up some first and I wont be able to get to that for another couple of days.

Thanks Smallike! It's alright, I will try to do it myself in the meantime. It is a pity OpenFeint people don't have a simple example explaining how to do these things...

Hi again! I have been able to do this sort of: I am posting what i did.Basically it changes the openfeint popups to cocos2d like. Right now i only have a label with the text fading in and out. The only thing i can't figure out is how to have the notification stay onscreen even if the scene changes... Also i don't know how to show the name and image of the unlocked archievement.

SmallMike, if you were able to do this, could you please give me a hint? Anyway this is what i do:

in my appDelegate:

- (BOOL)isOpenFeintNotificationAllowed:(OFNotificationData*)notificationData
{
	if(notificationData.notificationCategory == kNotificationCategoryAchievement)
		return NO;
	else
		return YES;
}

- (void)handleDisallowedNotification:(OFNotificationData*)notificationData
{
	Scene * current = [[Director sharedDirector] runningScene];
	CocosNode * nodo = [[NotificationLayer alloc] init:notificationData];

	[current addChild:nodo z:10];
	NSLog(@"%@",notificationData.notificationText);
}

Then

@implementation NotificationLayer
- (id) init:(OFNotificationData *)notificationData {
    self = [super init];
    if (self != nil) {

		//NSLog(@"%@",notificationData.notificationText);
		label = [Label labelWithString:notificationData.notificationText fontName:@"Arial" fontSize:20];
		[label setPosition:ccp(240, 40)];
		[label setOpacity:0];
		[self addChild:label z:10];
		[label runAction: [FadeIn actionWithDuration: 1.25]];
		[self schedule: @selector(estepi) interval: 5];

    }
    return self;
}

-(void)estepi
{
	[self unschedule: @selector(estepi)];
	[label runAction: [Sequence actions:
					   [FadeOut actionWithDuration: 1.25],
					   [CallFuncN actionWithTarget:self selector:@selector(callback:)],
					   nil]];
	NSLog(@"holaaaa");
}

-(void)callback: (CocosNode *)node
{
	[node.parent removeChild:node cleanup:YES];
}

-(void)dealloc
{
	[super dealloc];
	[[TextureMgr sharedTextureMgr] removeUnusedTextures];

}

@end

Hi again, sorry to ask this again, but i don't have a clue on how to do this:

I made the custom popup notification to appear in the current running scene, but i can't figure out how to make it remain whene the scene changes...

I suppose i would have to attach the popup layer to whatever scene i go to. (?)

Thanks!

Still couldn't figure this out... I have everything working except for the fact that the custom notification layer dissapears when changing the scene.

Could you give me some insight on how you solved this? Thanks!

In the onExit of your notification node, you can grab the next scene to be run from the Director, and add the notification to it. Take a look at the files here:

http://www.smallrocksoftware.com/Share/OpenFeintNotification.zip

Feel free to use those however you want. It should more-or-less work. There may be a few global defines used but you should be able to figure out your own values easily enough.

That worked perfectly, thanks! One last question, i promise!
How can i get the sprite for the achievement from the url i have in the OFachievement object?

Thanks!

We're just keeping copies of the icons within the app bundle itself rather than fetching them from OpenFeint. So when an achievement is unlocked, we obtain its resourceId and generate a local icon filename, e.g. "achievement-122435.png".

Saw this bumped up earlier in the evening and decided to give it a shot. Took me a little while to get how the OF delegates worked, but thanks to the code in this thread, it was much easier than figuring it out myself.

I'll contribute a code snippet.
```
-(void)handleDisallowNotification:(OFNotificationData*)notificationData
{
   if (notificationData.notificationCategory == kNotificationCategoryAchievement) {
     OFUnlockedAchievementNotificationData *data = notificationData;
     NSArray *component = [data.unlockedAchievement.iconUrl pathComponents];

     CustomOFNotification *custom = [[[CustomOFNotification alloc] initWithFile:[component lastObject] andWithText:data.unlockedAchievement.title] autorelease];

     [custom showNotification];
   }
}
```
Basically the last component of the URL is the name of the file you uploaded to OF. So I just took the directory of icons I uploaded to OF for achievements and added to the project. I wrote a CustomOFNotification class which displays the text and sprite.

I'm quite happy with the results! :D

That used to work well for me, but for some reason I am finding that the OpenFeint notifications cause a drop even if I don't do anything in the handleDisallowNotification. But when no notification is sent back to the client, it is fine. So for instance, say I reach the point in my game where I would achieve something, and I tell OpenFeint about it, but I have previously reached this, open feint doesn't send me a notification, and all is well, but if I hadn't reached that achievement, it does send me a notification, and I get a lag, which sometimes is worse than others, but in any case is very noticeable, particularly when the game is a fast paced game.

As best I can tell it has to do with networking. I'm really thinking of removing OpenFeint from my game, though I like the features.

I developed this notification system for cocos2d, It's very stable.

I used that for a while, and while it worked, it seems as of late, I get a lag when the notification fires, even when using your system. What is odd, I used to never get that lag. Granted, I have changed quite a bit of code in my game, and in most ways, made it a lot faster, but the notifications seem to have gotten bitten by a lag bug somehow. Haven't really been able to pin it down, but it definitely happens when I get a notification, whether I show it on screen or not. So I ended up writing my own that was much simpler, and worked well too for a while, but it too has been bitten by the lag. I would say it is a 4.0 thing, but I see it on my old 3.1.3 iPod touch devices too.

Well I found a solution that works for me... I keep the achievement id's in an array and at game's end send them up to OpenFeint. Not ideal, but does keep the game from lagging.
