I have a serious problem here, and I think it's Menu class's fault.

In my game on it's layer (which is touch-enabled) I have a couple of menu layers (for restart when you've won or lost)

These menus are getting touches even if they're zOrdered to -1 or set visible = NO or set to some far position, no matter what.

So when you play you could accidentally hit that invisible menu and it would work.

I even went to menu.m code and tried to set if(self.visible) on all the events.
I think the problem is with
[[TouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:INT_MIN+1 swallowsTouches:YES];
In menu.m:176

Please give some advice as to how to disable them for when they're invisible (i.e. game is in progress)

This is actually... really easy? In the documentation you'll see a function "setIsEnabled" for MenuItem. So try [menuItem setIsEnabled:NO]; Works like a charm.

No, I think mkrn is right... his change makes sense. If the layer is not visible, why would you propogate touches to it. Having to manually disable everything on the layer makes no sense to me.

Oh, and it seems that [menuItem setIsEnabled:NO] still eats the touch so that doesn't solve the problem anyway.

If you need it to just work and figure out the underlying(no pun intended, heh) problem later .. , for now, you could try just setting the menu position out of the visible screen, then when you need it again, move it back on screen.

-Scratch that.. just read that you already tried moving it off screen ..

What about setting isTouchEnabled for the Menu layer? I can certainly think of circumstances where you might want an invisible menu that still responds to touches and a visible menu that doesn't respond to touches so I don't think touch response should be tied to visibility.

Not sure if anyone needs this anymore but I found a pretty nice solution for the menu problem.

1. Take a subclass/helper file for CCSprite and add a method that adds it as a delegate of the touch dispatcher with a lower priority than CCMenu (something like -1000) and set it to swallow touches.
2. Use an instance of that class as the background to your popup menu to absorb all touches in background menus.
3. For your popup, subclass CCMenu and override registerWithTouchDispatcher and set the priority lower than your background (-1001, for example).

Hope that helps someone!
