I have a button that opens a menu in our level,
In implementing the Android onKeyEvent I also
want to be able to open that menu if the user presses
the actual device menu button.
However, I need a way so that this doesn't "spam" the device button
if the user hits it on the device more than once.

what can be added to the onKeyEvent code for such a thing?
example:

1
2
3
4
5
6
7
8
9
10
11
12

local function onKeyEvent( event )
        local returnValue = true
        
        if (event.phase=="up" and event.keyName=="menu") then
                timer.performWithDelay(100,openMenu,1)
        end
                
        return returnValue
end
 
-- Add the key callback
Runtime:addEventListener( "key", onKeyEvent )
