Tween onComplete

hi ppl,

i have a small problem, but some how i dont know how will be the best way to do it, iam new in actionscipt so, here it goes:

i want to, after a tween (by the way iam using the script TweenDelay) is complete that last 1 second, make the same object not visible, i have this

new TweenDelay(_root.obj, "_alpha", Regular.easeOut, 100, 0, 1, 0, true);

in here the object goes from _alpha 100 to 0, in 1 second with no delay, i want that after that second, when he is on _alpha = 0 to be _visible = false

i know that it must be easy but i didnt get it so far.

thx for the reply ppl.
