I want to implement ranking by using Game Center.
So , I implement like this .
-(void)authenticateLocalPlayer
{
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
localPlayer.authenticateHandler = ^(UIViewController *vc,NSError *err){
[self setLastError:err];
if ([CCDirector sharedDirector].isPaused){
[[CCDirector sharedDirector] resume];
}
if (localPlayer.authenticated){
_gameCenterFeaturesEnabled = YES;
// get localplayer's score.
GKLeaderboard *board = [[GKLeaderboard alloc] init];
// make a query
board.timeScope = GKLeaderboardTimeScopeAllTime;
// I want to get all player's score.
board.playerScope = GKLeaderboardTimeScopeToday;
// set my game category.
board.category = #"com.nobinobiru.shooting";
// I want to show top 3 score data.
board.range = NSMakeRange(1, 3);
[board loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) {
NSString *s = [NSString stringWithFormat:#"%lld",board.localPlayerScore.value];
[ud setObject:[NSString stringWithFormat:#"%#",s] forKey:#"bestScore"];
if (scores){
// I want to 3 items but it returned only 1 item.
NSLog(#"score is %#",scores);
}
}];
}else if (vc){
[[CCDirector sharedDirector] pause];
[self presentViewController:vc];
}
};
}
Then, I create 3 sandbox's user account , and I test it.
But it always only show current user's best score.
I want to show 3 sandbox's data.
I don't know why it happened like that.
My code works well in not sandbox environment?
Do you have any idea?
Thanks in advance.
All.
It works perfectly after 6 hours...
I think that the reason why it happened is my created game center account was not reflect immediately.

When launching an app I'm opening a Game center sign in dialog.It works first time. but when user presses cancel button it hides. and then clicking on the button that opens ui of leaderboard it doesn't show sign in dialog although I call sign in method if user is not signed in. Here's both methods...
bool GameSharing::signInPlayer(){
GKLocalPlayer *player = [GKLocalPlayer localPlayer];
bool signedIn=false;
[player authenticateWithCompletionHandler:^(NSError *error) {
//Just relax and do nothing
}];
if (player.isAuthenticated) {
signedIn = true;
}
return signedIn;
}
void GameSharing::openGameCenterLeaderboardsUI(int lId){
NSLog(#"Open Leaderboard UI");
if(iosLeaderboardIds.size() >= lId){
if (![GKLocalPlayer localPlayer].isAuthenticated) {
NSLog(#"not authenticated");
signInPlayer();
}else{
NSLog(#"authenticated");
AppController* appController = (AppController*) [UIApplication sharedApplication].delegate;
GKLeaderboardViewController* gkController = [[[GKLeaderboardViewController alloc] init] autorelease];
gkController.leaderboardIdentifier = [NSString stringWithUTF8String:iosLeaderboardIds.at(lId).c_str()];
gkController.timeScope = GKLeaderboardTimeScopeAllTime;
gkController.timeScope = GKLeaderboardTimeScopeToday;
gkController.leaderboardDelegate = appController;
[appController.viewController presentModalViewController:gkController animated:YES];
}
}
}
I'm not sure, but maybe there is some kind of delay before it pops up again? Maybe the functionality is designed so it shall only pop up once a day, unless the app is restarted. Just a guess.
I am developing a board game. Using Game Center for multiplayer, but currently stuck at how to send or receive invitations of GKTurnBasedMatch. I am creating match programmatically using:
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.defaultNumberOfPlayers = 2;
[GKTurnBasedMatch findMatchForRequest:request
withCompletionHandler:
^(GKTurnBasedMatch *match, NSError *error) {
if(error) {
NSLog(#"%#", error.localizedDescription);
return;
}
[self.delegate startGameForMatch:match];
}];
The GKTurnBasedMatch instance in parameter of above block, has only local player with other player as nil and I need to display details of opponent in the game.
NSMutableArray *participantIds = [[NSMutableArray alloc] init];
NSLog(#"%#", match.participants);
for (GKTurnBasedParticipant *participant in match.participants) {
if(participant.playerID) [participantIds addObject:participant.playerID];
}
[GKPlayer loadPlayersForIdentifiers:participantIds
withCompletionHandler:^(NSArray *players, NSError *error) {
NSMutableString *string = [[NSMutableString alloc] init];
for (GKPlayer *player in players) {
[string appendFormat:#"---- Alias: %# DisplayName: %#", player.alias, player.displayName];
}
NSLog(#"%#", string);
}];
Am I missing something or Game Center works like this?
I read that participants of the match wont get invitations until that GKTurnBasedParticipant is GKTurnBasedMatch.currentParticipant but I need to display the details of opponent when game started.
Thanks for the help. Point me in correct direction.
This happens when you create a match against a random opponent. Try creating a second test user in iTunesConnect and signing into that user on a second device.
Then, send that second test player an invite to be your friend. This will allow you to more easily test your game with multiplayer features without having to wait for a random match to be found.
After the friend request is accepted, try creating a new game once more. Now, invite your 'Friend' to your game and start your turn. You will now notice that the (null) variables will - for the most part - be filled in. Something like this should now appear in your log-
GKTurnBasedParticipant 0xb9432e0 - playerID:G:123456789 status:Invited matchOutcome:None lastTurnDate:(null) timeoutDate:(null)
I'm trying to create a custom view controller to display active games to the user (similar to what Letterpress does).
I am currently trying to subclass GKTurnBasedMatchmakerViewController except I don't know how to hide the default elements (for inviting/showing existing games) and to add my own. I have currently been playing around with logging things to ensure I can access the active matches, current player IDs, etc (which I have recently figured out) but I am stuck on how to start with the interface.
Not sure what code, if any would be relevant at this point. Please let me know.
Looking to: Hide current elements. I'm assuming I can build the interface as I would for any other application after that.
Thanks,
Steven
I don't think its a good idea to subclass. Start with a clean UIViewController and build the UI from there. Then implement all the necessary methods.
Set yourself as delegate:
[GKTurnBasedEventHandler sharedTurnBasedEventHandler].delegate = self;
so you get delegate event, such as:
handleInviteFromGameCenter
handleTurnEventForMatch
handleMatchEnded
etc.
Add a UITableView, and load all matches from Game center:
[GKTurnBasedMatch loadMatchesWithCompletionHandler:^(NSArray *matches, NSError *error) {
// Add matches to table view
}];
Don't forget to authenticate the player first:
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
localPlayer.authenticateHandler = ^(UIViewController *loginVC, NSError *error)
{
};
Star a match programatically:
GKMatchRequest *request = [[GKMatchRequest alloc] init];
request.minPlayers = 2;
request.maxPlayers = 2;
[GKTurnBasedMatch findMatchForRequest:request withCompletionHandler:^(GKTurnBasedMatch *match, NSError *error)
{
}];
etc. Look at the doc for the full API.
I have a game that uses Game Center.
I'm playing the game, when the game ends, I send my score to GC. After that, I'm checking my score with the method below.
- (void)showLeaderboard
{
GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if (leaderboardController != NULL)
{
leaderboardController.category = self.currentLeaderBoard;
leaderboardController.timeScope = GKLeaderboardTimeScopeAllTime;
leaderboardController.leaderboardDelegate = self;
UnityAppController* delegate = (UnityAppController*)[[UIApplication sharedApplication] delegate];
[[delegate rootViewController] presentViewController:leaderboardController animated:YES completion:nil];
}
}
That's just working fine, when I check it I can see my recent score on the leaderboard.
But the problem starts after. The next day, when I check it again with the showLeaderboard() method, the leaderboard says "no score". If I play the game and send my score again it's just working fine again, I can see my score! But, the next day the leaderboard says "no score" to me again! Like the leaderboard resets itself at 00.00 o'clock.. Just awkward..
Any suggestions? Thanks in advance..
Just make sure that you do the correct code for submitting the score. This is a way that I really like. Even though you will get warnings because they don't want you to use it in iOS 7, it still works. Just let me know if it doesn't work.
(IBAction)submitscoretogamecenter{
GKLocalPlayer *localplayer = [GKLocalPlayer localPlayer];
[localplayer authenticateWithCompletionHandler:^(NSError *error) {
}];
//This is the same category id you set in your itunes connect GameCenter LeaderBoard
GKScore *myScoreValue = [[[GKScore alloc] initWithCategory:#"insertCategory"] autorelease];
myScoreValue.value = scoreInt;
[myScoreValue reportScoreWithCompletionHandler:^(NSError *error){
//insert what happens after it's posted
}];
[self checkAchievements];
}
I'm in sandbox mode implementing game center in my application. The problem comes when I log to gameCenter, in some devices works fine in some others I get a GKErrorCanceled without even get the interface shown.
This devices don't have any user logged in gameCenter so it's not related to have a non sandbox account logged. My code is:
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
//First we try the new iOS6 authentification method for gamekit, if it's not implemented we will use the deprecated one
if ([localPlayer respondsToSelector:#selector(setAuthenticateHandler:)]) {
if (localPlayer.isAuthenticated) {
this->setState(connectionLoged);
this->getDelegate().socialConnectionDidSucceedLogin(*this);
return;
}
else if(!localPlayer.isAuthenticated && localPlayer.authenticateHandler){
this->setState(connectionClosed);
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string("The user already resign to login"));
return;
}
else{
localPlayer.authenticateHandler = ^(UIViewController* viewController, NSError* error){
if (localPlayer.isAuthenticated)
{
_name = [localPlayer.displayName UTF8String];
_userId = [localPlayer.playerID UTF8String];
[GKPlayer loadPlayersForIdentifiers:localPlayer.friends withCompletionHandler:^(NSArray *players, NSError *error) {
for (GKPlayer* player in players) {
if ([player isFriend]) {
NSDictionary* dict =
#{#"displayName" : player.displayName,
#"alias" : player.alias,
#"playerID" : player.playerID};
AttrDictionary* playerInfo = [dict hydraAttrDictionary];
SocialFriend* socialfriend = this->getNewFriendInstance(*playerInfo);
this->addFriend(socialfriend);
delete playerInfo;
}
}
this->getDelegate().socialConnectionDidSucceedLogin(*this);
this->setState(connectionLoged);
}];
}
else if(viewController){
UIViewController* rootViewController = (UIViewController*) [UIApplication sharedApplication].keyWindow.rootViewController ;
[rootViewController presentModalViewController:viewController animated:YES];
}
else{
if(error){
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string([error.description UTF8String]));
}
else{
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string("User cancelled login"));
}
}
};
}
}
//deprecated at IOs 6 authentification method
else
[localPlayer authenticateWithCompletionHandler:^(NSError *error) {
if (localPlayer.isAuthenticated)
{
_name = [localPlayer.displayName UTF8String];
_userId = [localPlayer.playerID UTF8String];
[GKPlayer loadPlayersForIdentifiers:localPlayer.friends withCompletionHandler:^(NSArray *players, NSError *error) {
for (GKPlayer* player in players) {
if ([player isFriend]) {
NSDictionary* dict =
#{#"displayName" : player.displayName,
#"alias" : player.alias,
#"playerID" : player.playerID};
AttrDictionary* playerInfo = [dict hydraAttrDictionary];
SocialFriend* socialfriend = this->getNewFriendInstance(*playerInfo);
this->addFriend(socialfriend);
delete playerInfo;
}
}
this->getDelegate().socialConnectionDidSucceedLogin(*this);
this->setState(connectionLoged);
}];
}
else{
NSString* errorString = [error localizedDescription];
this->getDelegate().socialConnectionDidFailToLogin(*this, std::string([errorString UTF8String]));
this->setState(connectionClosed);
}
}];
I need the code compatible with iOS 6 and iOS 5 so you will see I have the two implementations. For iOS 6 the completion handler returns with an UIViewController null and the error as I say. I'm afraid that in production it happends the same. In the simulator all works fine.
PS- You will find some c++ code, it's because I implement a c++ wrapper for GameCenter as my game is write in cocos2dx...
When someone cancels out of the interface to sign in to game center, it will give you GKErrorCanceled. The third time in a row that they cancel, it will warn them that it will disable game center.
If they do choose to disable game center, then it won't show the interface anymore, and it will just give you GKErrorCanceled instead.
Once game center has been disabled, the only way to sign in is by going into the actual game center app.
The 3 times in a row could be in any app or any combination of apps that use game center, and game center will be disabled for all apps that use game center. The 3 times in a row restarts every time they sign in to game center.
This is for both sandbox and non-sandbox.
This is for both ios 5 and ios 6.
