GC Achievements problem

[JoKa]

I have 3 achievements based on percentage:
Amateur (the Player kicked 10 times to reach 100%)
Pro (the Player kicked 50 times to reach 100%)
Champ (the Player kicked 100 times to reach 100%)

I make the first kick and send these values, a counter prevents sending multiple achievements at the same time, it goes one after the other:
Amateur 1%*10
Pro 1%*2
Champ 1%

The result: in GC all achievements are set to 10%

What's wrong? Do I miss something?

Not sure what you mean by 10% but the achievement in GC work by one-timed activation. That's mean you get or not get the said achievement, there's no progress like Steam. The point for each achievement is there just to show how great that thing is, no real meaning what so ever.

So what you should do is tracking the progress for all 3 achievement within your game and send each one once the player get it.

[JoKa]

I don't mean the GC point values which are shown for each achievement. When you send a percentage below 100, you can see the progress at the achievement's icon: a circle that grows around the yet unlocked icon and a small number showing the current percentage.

So, when I send the first kick to the Amateur achievement, I calculate 1*10=10
Since 10 kicks=100% the first kick means 10% completion. And it worked for this single achievement: it's circle and completion value were 10%, as I sent.

My problem are the two other achievements. After the first kick Amateur is at 10%, but so are Pro and Champ. I sent a percentage of 2 for Pro and 1 for Champ, but they show a completion of 10% instead of 2% and 1%.

Then perhaps you may try making 3 separate value. You should be able to track it better that way.

Would it be possible that GameCenter does not accept reporting achievement progress under 10%? I didn't find any information about this.
Or maybe only integer or float values are accepted, did you try both JoKa?

Maybe the problem is reporting progress on multiple achievements at once. Apple shows a specific example for this:

You can report values under 10% but you can't set achievements lower than they already are. If you previously set an achievement to 10% you can't set it to anything lower.
However you can reset all achievements and then set them again.

Currently the extension doesn't have this functionality though, so I had to manually add the code myself to another function of the object in order to make it work.

Also there is a bug in the current version of the extension that I posted a fix for a while back. It'll be in the next update.

Gamecenter Achievement Fix:

Apple Documentation:

Replace the function "sendAchievement" with the following code:

-(void)sendAchievement:(CActExtension*)act
{
     NSString* identifier=[act getParamExpString:rh withNum:0];
     int percent=[act getParamExpression:rh withNum:1];

     //Create a GKAchievement object and attach the ID and percent
     GKAchievement *achievement = [[GKAchievement alloc] initWithIdentifier: identifier];
     achievement.percentComplete = percent;

     //Send the data to GameCenter
     [achievement reportAchievementWithCompletionHandler:^(NSError *error) {}];
     flags|=FLAG_SENDACHIEVEMENT;
}

Replace one of the object's function with the following code:

[GKAchievement resetAchievementsWithCompletionHandler:^(NSError *error){}];

Thank you very much UrbanMonk, seems like your fix is exactly what JoKa needs. And I'm glad to know that an official fix will be available soon.

About the achievement reset, I don't undersand why this has still not been implemented. I remember asking for it more than a year ago.

[Anders]

Just a note:
UrbanMonk's fix prevents the 'Achievement sent' condition from triggering.

The most recent release should have a better working GameCenter:

Thanks for your advice!
