Error addEventListener: listener cannot be nil: nil

It tells you what the error is. You’re not adding the listener in the same way the docs state:

local object = display.newImage( "image.png" ) function object:touch( event ) if event.phase == "began" then print( "You touched the object!" ) return true end end object:addEventListener( "touch", object )

You can also add a listener like this:

local object = display.newImage( "image.png" ) local touchObject = function (event) if event.phase == "began" then print( "You touched the object!" ) return true end end object:addEventListener( "touch", touchObject )

And I checked docs it says what enterFrame must be with Runtime:

Well, what line is the error actually occurring on? We don’t know what line 179 is in your code from your initial post.

Now I just get an error what doesn’t say line…(I put all listeners outside composer functions)

In SpaceMap.lua 5th line there is goto scene function

And in lobby.lua 41st line there is same goto scene function

Any help?

At some stage you have to learn to debug. Somewhere you are adding a listener that is nil. So how about everywhere in your code where you are about to add a listener, do print(object, listenerToAdd) first. If either show in the console as nil, there’s your problem. Then you can trace backwards through your code to find out why it is nil. It will usually be a scoping issue. 

  object:addEventListener("touch", touchListener) -- this will break   local touchListener = function (event)   end   object:addEventListener("touch", touchListener) -- this will not

Sorry but that’s nonsense, semi-colons are completely optional in lua and serve no practical purpose.

:huh:  I tested it and now it works without “;”

Very strange…
