I want to know if I have two instances of the same movie clip
and they are rendered one over the other, the image not visible
will impact performance at the same way the one visible. My
question is because I am trying to detect collision using
invisibles mc over the real one, but after I set visible option to
false, detection can not be achieved, so I was thinking just to
render the collision object under the real object. However I am
concern about performance.
One suggestion I got was to set alpha to 0. This is the best
way to do it?
I am using getObjectsUnderPoint to detect collision object.
