remove object from a scene on tween complete

boriskey

Hi guys,

how I can modify this example to remove the object (sprite) from a scene once tween animation is complete?

myscene.lua:
------------------

local tween = GTween.new(sprite, 10, animate, properties)

--adding event on animaiton complete
tween:addEventListener("complete", function()
stage:removeChild(sprite)
sprite = nil
end)

Basically in my scene I have some special effect that will produce 5-10 sprites and animate them and after 1 second should kill them.

@boriskey
to remove sprite from any parent just call sprite:removeFromParent()

so you don't care what parent is stage or scene

or I mis interpreted your question?

i got it right and it did the trick - thanks! I am a bit puzzled though why it works - how come anonymous function actually remember local variable defined outside of it? is this Lua's magic?

@boriskey yes lua has scope levels, and as anonymous function is defined in the same scope, deeper scopes can see variables (through look up of course, the further level, the more lookups) that are define on previous scope levels

interesting, thanks!
