How could remove event listener properly

Rickyngk

Hi,

For quick implement, sometimes I use addEventListener as following:

mySprite:addEventListener("onMyEvent", function(event) print("active my event") end )

However, I don't know how to remove that event listener, because I can't get "listener" value.

EventDispatcher:removeEventListener(type, listener, data)

Count I remove all listeners of type, without declare listener and data?

Thanks,

I would actually recommend NOT using anonymous functions (or closures) in that way for that very reason.

local listener = function(event) print("active my event") end mySprite:addEventListener("onMyEvent", listener)   mySprite:removeEventListener("onMyEvent", listener)

You only need to be aware of scopes, if you remove listener in other scope, then you either make listener as property of bigger scope (as class, for example), or make it global.

Well I could be wrong, but I do this....
local timer = Timer.new(5000, 1)
timer:addEventListener(Event.TIMER,
function(event)
--[[Do my shit here in 5 seconds]]
end
)
timer:start()

@Cyberience Also there is a shortcut for this:

Timer.delayedCall(5000, function() -- do your stuff end)
