Question

So basically I have a protocol inside my interface that I need to include in my implementation because I am getting an incomplete error and therefore can’t continue.

. h file

@interface waveLayer1 : CCLayer <GameKitHelperProtocol>
{
    ...
}

.m file

@implementation waveLayer1 

GameKitHelper.h file

#import "cocos2d.h"
#import <GameKit/GameKit.h>
@protocol GameKitHelperProtocol
-(void) onLocalPlayerAuthenticationChanged;
-(void) onFriendListReceived:   (NSArray*)friends;
-(void) onPlayerInfoReceived:(NSArray*)players;
@end

@interface GameKitHelper : NSObject {
    id<GameKitHelperProtocol> delegate; bool isGameCenterAvailable; NSError* lastError;
}
@property (nonatomic, retain) id<GameKitHelperProtocol> delegate;
@property (nonatomic, readonly) bool isGameCenterAvailable; @property (nonatomic,    readonly) NSError* lastError;

+(GameKitHelper*) sharedGameKitHelper;
// Player authentication, info
-(void) authenticateLocalPlayer;
-(void) getLocalPlayerFriends;
-(void) getPlayerInfo:(NSArray*)players; 
@end  

The error is “Method in protocol not implemented” I have more files I can show ,but to save room I decided to see if you can help me fix this with just these codes

Implement these 3 methods in your waveLayer1 class..

-(void) onLocalPlayerAuthenticationChanged;
-(void) onFriendListReceived:(NSArray*)friends;
-(void) onPlayerInfoReceived:(NSArray*)players;
