HUD教程爲cocos2d

Question

我試過按照這個教程（http://www.raywenderlich.com/4666/how-to-create-a-hud-layer-with-cocos2d）但是你可能會告訴我我沒有用這個教程來做與他們相同的事情，而是爲了一個幾乎相同的設置。我相信我一直在跟着它。但是我得到的誤差（由箭頭示出的位置：< ----） '未知類型名稱 'settingsMenu'' 和 '分別預期類型'：

mainMenu.h：

// mainMenu.h 


#import <Foundation/Foundation.h> 
#import "cocos2d.h" 
#import "Constants.h" 
#import "SceneManager.h" 
#import "settingsMenu.h" 



@interface mainMenu : CCLayer { 
    settingsMenu * _settings; <---- 
} 

@property (nonatomic, assign) BOOL iPad; 

+ (id)scene; 
- (id)initWithsettingsMenu:(settingsMenu *)settings; <---- 

@end 

MAINMENU。米：

// mainMenu.m 

#import "mainMenu.h" 
#import "gameData.h" 
#import "gameDataParser.h" 
#import "SimpleAudioEngine.h" 
#import "settingsMenu.h" 

@implementation mainMenu 

@synthesize iPad; 

+ (id)scene { 
    CCScene *scene = [CCScene node]; 
    settingsMenu *settings = [settingsMenu node]; 
    [scene addChild:settings z:1]; 
    mainMenu *menuLayer = [[[mainMenu alloc] initWithsettingsMenu:settings] autorelease]; 
    [scene addChild:menuLayer]; 

    return scene; 
} 

settingsMenu.h：

// settingsMenu.h 

#import <Foundation/Foundation.h> 
#import "cocos2d.h" 
#import "Constants.h" 
#import "SceneManager.h" 

@interface settingsMenu: CCLayer { 
    CCMenuItem *_musicOn; 
    CCMenuItem *_musicOff; 
    CCMenuItem *_invertControlsOn; 
    CCMenuItem *_invertControlsOff; 
} 

@property (nonatomic, assign) BOOL iPad; 
@property (nonatomic, assign) BOOL settings; 

@end 

settingsMenu.m：

// settingsMenu.m 


#import "settingsMenu.h" 
#import "gameData.h" 
#import "gameDataParser.h" 
#import "SimpleAudioEngine.h" 
#import "mainMenu.h" 


@implementation settingsMenu 

- (id)init{ 
    if((self=[super init])) { 

     // Determine Screen Size 
     CGSize screenSize = [CCDirector sharedDirector].winSize; 

     self.iPad = UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad; 

     if (self.iPad){ 
      CCSprite *background = [CCSprite spriteWithFile:@"settingsiPad.png"]; 
      background.position = ccp(screenSize.width/2, screenSize.height/2); 
      [self addChild:background]; 
     } 

     else if (screenSize.height > 490){ 
      CCSprite *background = [CCSprite spriteWithFile:@"settingsiPhoneFive.png"]; 
      background.position = ccp(screenSize.width/2, screenSize.height/2); 
      [self addChild:background]; 
     } 

     else{ 
      CCSprite *background = [CCSprite spriteWithFile:@"settingsiPhone.png"]; 
      background.position = ccp(screenSize.width/2, screenSize.height/2); 
      [self addChild:background]; 
     } 
    [self addButtons]; 

    } 
    return self; 
} 

感謝您的時間！我不認爲有必要發佈任何更多的代碼，但如果有其他地方可能導致這個問題，請讓我知道，我會張貼代碼。

的gameLayer .H：在.M你

@synthesize HudLayer; 

然後在init（我拿出大部分不必要的東西）

// GameLayer.h 

#import <Foundation/Foundation.h> 
#import "cocos2d.h" 

@interface GameLayer : CCLayer { 
    CCLayer *HudLayer; 
} 
@property (nonatomic, retain) CCLayer *HudLayer; 

+(id)scene; 
@end 

然後，

//HUD Layer setup 

     HudLayer = [[[CCLayer alloc] init] autorelease]; 
     [self addChild:HudLayer]; 
      //add stuff in the HUD here... 


     CCMenuItem *Mainmenu = [[[CCMenuItemFont itemWithString:@"Main Menu" target:self selector:@selector(MainMenu:)] retain]autorelease]; 

     Mainmenu.position = ccp(size.width /2-Mainmenu.rect.size.width,size.height /2-Mainmenu.rect.size.height); 
     CCMenu *Hudmenu = [CCMenu menuWithItems: Mainmenu, nil]; 
     [HudLayer addChild:Hudmenu]; 
    //End HUD Layer setup
