Cocos2d: is there a way to access to a CCMenu child?

Question

I am using the following code:

CCMenuItemFont *controllerItem = [CCMenuItemFont itemFromString:@"Analog" target:self selector:@selector(controllerToggle)];

    CCMenu *controllerTypeMenu = [CCMenu menuWithItems:controllerItem, nil];
    [controllerTypeMenu alignItemsVerticallyWithPadding:30.0f];
    controllerTypeMenu.position = CGPointMake(160.0f, 240.0f);
    [self addChild:controllerTypeMenu z:0 tag:ControllerMenu];
}  

-(void) controllerToggle
{
    CCMenuItemFont *controllerItem = [self getChildByTag:888];
    NSString * text = [NSString stringWithFormat: @"switching.. %f", CCRANDOM_0_1()];
    [controllerItem setString:text];
}

In controllerToggle I would like to access to controllerItem and change the String to another value. Is this possible? I checked and CCMenu adds as child the CCMenuItems based the array order. But that's not an elegant solution. For the same reason I cannot add the CCMenuItem to the Scene as it will give me "child already added error". So I feel I should write my own "switch" button but I wonder if there is already something out there..

Any help?? Thanks!

Answer 1

you can declare needed menu item as class member. In this way you will be able to get access to it whenever you want

Answer 2

There is already CCMenuItemToogle which is used to switching the title or image of any menuitem on click event.Instead of taking CCMenuItem you can use CCMenuItemToggle..

Here is a sample code CCmenuItemToggle *cam=[CCMenuItemToggle itemWithTarget:self selector:@selector(openCameraController) items:cameraOn,cameraOff, nil]; where cameraOn and cameraOff are two simple CCMenuItemImage which is added in CCMenuItemToggle and further this CCmenuItemToggle is added in a menu.

Now on every click of CCMenuItemToggle there will be a cameraOn and cameraOff state for same menuitem.

Hope this will help...
