You're welcome Ali :)
By making more sense I didn't particularly meant clarity, but ease of use.
For example, if you're calling this function from method(s)that hardcode the
passed clips like in your example, then using arguments makes sense.
But what if you're dynamically retrieving those clips with some code,
possibly including some and excluding others? In that case, sticking them
into an array while you're retrieving them makes more sense. And then all
you need to do is pass that array.
Just as a very rough example -
var myMC = containingClip.firstOne;
var clips:Array
for (var i in containingClip){
if (containingClip[i]._name.indexOf("center") > -1){
clips.push(containingClip[i]
}
}
center(myMC, clips)
Similarly (and I'm straying a bit off topic here, so I hope you don't mind)
when you're passing a variable number of arguments as options, it's easier
to create an options object first and pass that instead of loads of
arguments:
var options:Object = {}
options.delay = 500;
options.html = true;
options.follow = true;
Tooltip.show("Tooltip Text", options)
Does that make any sense?
