   I'm a student of Girona (Spain) and i'm working to do a game for iphone, I read documents and tutorials but i have problems that i don't understand.

   I have a menu class with 3 menuItems (start, options and extras), when the user touch the start he goes to the Game class. This class is a scene with two class variables: ActionLayer and controlLayer. The first have the method tho load the map and move the sprite, and the second the events and the controllers to move the sprite (right, up, down and left).

   My questions are:

   - In a gameScene, i would like to have the map and the sprite (the layer of the class ActionLayer) and the controllers for the sprite (controlLayer). Is correct this approach with my classes?

   - The game load the map correctly, but in the controlLayer the init i would like to add four labels or menuItems (the directions for the movement), and when i build up the project, i can't see this menuItems.

   Thanks for all !

   Take a look at this:

   In the init method

   [MenuItemFont setFontSize:28];
   [MenuItemFont setFontName:@"Helvetica"];
   MenuItem *start = [MenuItemFont itemFromString:@"Start Game"
   target:self selector:@selector(startGame:)];

   MenuItem *options = [MenuItemFont itemFromString:@"Options"
   target:self selector:@selector(options:)];

   MenuItem *help = [MenuItemFont itemFromString:@"Help" target:selfselector:@selector(help:)];

   Menu *menu = [Menu menuWithItems:start, options, help, nil];
   [menu alignItemsVertically];
   [menu setPosition:cpv(160, 170)];
   [self addChild:menu];

   I have the same code in the MenuGame. My problem is that i can't see the control layer, the GameScene i have:

   ActionLayer *actionLayer;
   ControlLayer *controlLayer;

   The actionLayer is:

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

   if (self)
   {
   [self schedule: @selector(tick:) interval:frameRate];
   }

   return self;
   }

   And it had a

   TileMapAtlas *tileMap;
   MapData *mapData;

   And the problem is here, the controlLayer:

   @interface ControlLayer : Layer
   {
   id delegate;
   Sprite *controlChart;
   }

   and the init i take a similar code from the menuScene and i can't see it.

   Thanks for all!

   Hi! Are you adding both layers as child of the scene?
   Can you post you scene's init method to see what you are doing?

   This is my init from GameScene:

   - (id) init {

   self = [super init];

   if (self)
   {

   self.accion = [[Acciones alloc] init];
   self.control = [[Controladores alloc] init];

   [self addChild:accion];
   [self addChild:control];

   [accion loadLevel:1];

   }

   return self;

   }

   And this is the init from the controlLayer(Controladores):

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

   if (self)
   {
   self.isTouchEnabled = YES;

   [MenuItemFont setFontSize:20];
   MenuItem *adelante = [MenuItemFont itemFromString:@"Adelante"];
   MenuItem *atras = [MenuItemFont itemFromString:@"Atras"];
   MenuItem *izquierda = [MenuItemFont itemFromString:@"Izquierda"];
   MenuItem *derecha = [MenuItemFont itemFromString:@"Derecha"];
   Menu *movimiento = [Menu menuWithItems:adelante, atras, izquierda, derecha, nil];
   [movimiento alignItemsVertically];
   [self addChild:movimiento];

   }

   return self;
   }

   And i can't see it.

   And finally the .h:

   @interface Layer (ControladoresDelegate)

   - (void) goUp;
   - (void) stopUp;

   - (void) goDown;
   - (void) stopDown;

   - (void) goLeft;
   - (void) stopLeft;

   - (void) goRight;
   - (void) stopRight;

   - (void) doActionA;
   - (void) stopActionA;

   - (void) doActionB;
   - (void) stopActionB;

   @end

   @interface Controladores : Layer
   {
   id delegate;
   Sprite *controlChart;
   }

   Then check in your scene code:

   [self addChild:accion];
   [self addChild:control];

   change their z to position one on top of the other. (i don't remember if you can just set the z or you have to also set the tag, anyway...

   [self addChild:accion tag:1 z:0];
   [self addChild:control tag:2 z:1];

    I add the z and nothing change, the compiler say me that not respond the method addChild with tag.

    Do you speak spanish?

    sorry, it was the other way, [self addChild:accion z:0 tag:1];
    anyways, you can try it without the tag, just [self addChild:accion z:0]

    Yes, i do speak spanish, i am from Argentina.

    Thanks!!! Now the control is up the map :) Sorry, other question, do you know how I can change the color of the menuItem? I search for the forum and I don't find the answer.

    Gracias de nuevo!

    try myMenuItem.color = ccc3(255, 0, 0); //red!

    for more info search cocos sourcecode for the type "ccColor3B" and the protocol "CocosNodeRGBA". Not every type of node responds to color changes - but any MenuItemLabel subclass should.

    re: [adelante.label setRGB:0 :0 :0];

    fyi, the -setRGB::: method is deprecated. Its will be removed in the next major release of Cocos2d. If you are using Cocos2d v 8.x try the property I suggested and see if you dont get the same results - then at least you will be compatible with future versions of cocos. Good luck.

    @agfa555 - going to need to see your code to help. you have to replace myMenuItem with the menu item name your using.
