Hi, I am writing an app that has two listners, one for touch events and one for tap events. The touch listener function works fine but when I try to add a listener to deal with taps on buttons they give an assertion errors. Here are the snippets.
local background = display.newImageRect( “bg.png”, 480, 320 )
local greenButton = display.newImage(“greenButton.png”, 400, 230)
local redButton = display.newImage(“redButton.png”, 20, 230)
the local onTouch(event) function works fine with this call
background:addEventListener( “touch”, onTouch)
Here is the tap listner function:
local function tapListener( event )
local object = event.target
print( object.name…" TAPPED!" )
end
I call it like this:
greenButton:addEventListener(“tap”, tapListener)
redButton:addEventListener(“tap”, tapListener)
When I launch it in the simulator I get this error:
Runtime error
assertion failed!
stack traceback:
[C]: in function ‘assert’
?: in function ‘getOrCreateTable’
?: in function ‘addEventListener’
?: in function ‘addEventListener’
It refers to the line which contains the first tap listener call.
This one has me stumped. Be most grateful for any insight.
Thanks
