Is it true to say that a Layer , with regards to Touches , covers the whole screen , regardless of its contentSize ?
ie. touches are still 'caught' by the layer if the touch happens 'outside' of its contentSize and its upto the touch handlers in the layer to figure out if the touch is for the layer (ie. within its contentsize ) .

Hi,
Sorry for hijacking the thread. All the documentation states that Layers fill the entire screen, but I am assuming you can position and size layers so they dont fit the whole screen? i.e. if you want the bottom half of the screen to respond to touches or acceleromator , but the top half not to - can you place two layers on the screen - each only taking up half the physical screen space (and even the top one being parallax capable?).

In your Layer's touch event code you can decide if you want that Layer to handle the touch or not - so you could test to see if the event is within certain bounds. If you return NO then cocos will send the event to other Layers to see if they want to handle it. So you could have multiple Layers where each Layer handles touches only if its within a certain area. Does that make sense?

Hi,
Thanks, I think so, but I want a layer at the bottom with hud and controls, and above that, I wanted a game layer - which would scroll vertically. I had thought about having an 80/20 layer split with the hud / buttons in a layer taking up the bottom 20%. Is this not possible - I take it from the reply that layers so fit the screen exactly. In which case how does parallax work..I had thought they were just extremely large layers..!
I have been able to setPosition of the layers, but have not idea how to control size.
Thanks

Oh, perfect! So, I have a GenericLayer that does an event (returns isActive). A button sprite or something. I place two GenericLayers on a scene to make a joypad. Each GenericLayer covers the whole scene, screen, winSize so only the top GenericLayer is accepting touches.
If i return kEventHandled = NO in the GenericLayer touch callback, the touch is then sent on to other layers?
