Question

my scene has 2 layers, game,and buttons, with :

+(CCScene *) scene
{
    // 'scene' is an autorelease object.
    CCScene *scene = [CCScene node];

    // 'layer' is an autorelease object.
    mainScene *layer = [mainScene node];
    buttons *layer2=[buttons node];
    layer.tag=30;
    layer2.tag=40;
    [scene addChild:layer2 z:1];
    [scene addChild: layer];

    // return the scene
    return scene;
}

then i am trying to make him invisible when touch on screen with :

[[self getChildByTag:40] setVisible:NO];

nothing is happen.

what am i doing wrong ?

thanks a lot .

The scene contains the layer, not self, so you need to call [[[self parent] getChildByTag:40] setVisible:NO];
