[Flashcoders] Take movieclips from one mc and attach to another
Hello!
I've found a nice code (pasted at the bottom of
this mail) to display a rotating set of movieclips.
One problem with it is though that it assumes
a hardcoded set of 7 movieclips in the library,
called 0, 1, ... 6 and attaches them to the
stage by calling attachMovie(i, mc+i, i);
I'd like to change that to a MovieClip-based class
which would take an arbitary array of MovieClips
and attach them to itself:
class Ellipse extends MovieClip {
private var mcs:Array = [];
...
public function setMovieClips(mcs:Array) {
this.mcs = mcs;
for (var i:Number = 0; i mcs.length; i++) {
var mc:MovieClip = mcs[i];
// XXX this.attachMovie(i, mc+i, i);
And here comes the problem - how do I attach
MovieClips (referred by mc above) to the Ellipse?
There are only 2 methods - attachMovie() and
duplicateMovieClip() - and they both need a linkage
name as the argument.
I.e. my general question is: how do I remove
a child-MovieClip from one parent-MovieClip
and assign it to another parent-MovieClip?
Regards
Alex
PS: Here is the original code
var N:Number = 7;
var A:Number = 150;
var B:Number = 50;
var X:Number = 200;
var Y:Number = 150;
var GR:Number = Math.PI / 180;
for (var i:Number = 0; i N; i++) {
attachMovie(i, mc+i, i);
this[mc+i].alpha = 0+i*(360/N);
this[mc+i].onEnterFrame = function() {
this.alpha += (_root._xmouse - X) / 100;
this._x = X + A * Math.cos(this.alpha * GR);
this._y = this._xscale = this._yscale =
Y + B * Math.sin(this.alpha * GR);
this.swapDepths(this._y);
};
}

You can't re-parent MovieClips in AS2. You could make your class control
arbitrary MovieClips as if they were reparented with a lot of math and
localToGlobal() calls, though. Probably not a great idea, though.

Re: [Flashcoders] Take movieclips from one mc and attach to another
Thanks, but can't I this.duplicateMovieClip() the
MovieClips passed to my class as arguments to its method
and then removeMovieClip the original?
Or createEmptyMovieClip() and the loadMovie() into it?
Regards

Re: [Flashcoders] Take movieclips from one mc and attach to another
I don't think having the class extend MovieClip is the right way to do this.
I'd just create a class and pass it an array of linkage names in which to
attach. Try this:
class Ellipse
{
function Ellipse(attachTo:MovieClip, linkageArray:Array)
{
var N:Number = linkageArray.length;
var A:Number = 150;
var B:Number = 50;
var X:Number = 200;
var Y:Number = 150;
var GR:Number = Math.PI / 180;
var ref:MovieClip;
for (var i:Number = 0; i N; i++) {
ref = attachTo.attachMovie(linkageArray[i], linkageArray[i], i);
ref.alpha = 0+i*(360/N);
ref.onEnterFrame = function() {
this.alpha += (_root._xmouse - X) / 100;
this._x = X + A * Math.cos(this.alpha * GR);
this._y = this._xscale = this._yscale = Y + B * Math.sin(this.alpha *
GR);
this.swapDepths(this._y);
};
}
}
}
Then in Flash pass the constructor an attach to clip, and an array with
linkage names.
var e:Ellipse = new Ellipse(this,
[sym_1,sym_2,sym_3,sym_4,sym_5,sym_6,sym_7]);
PS - this way you can use a variable number of clips also - you don't need
to use seven.
