Hey,

I'm having problems with this script:
Code: [ Select ]
stop();

_root.threads = new Array();

_root.createEmptyMovieClip("lines", 0);
_root.lines.count = 0;
_root.createEmptyMovieClip("links", 1);
_root.links.count = 0;

_root.id = "home";

MovieClip.prototype.addLinks = function(isFirst) {
    this.linksXML = new XML();
    this.linksXML.ignoreWhite = true;
    this.linksXML.load("http://www.particlesystem.com/particlesystem/assets/get_links.php?id="+this.id);
    this.linksXML.onLoad = function() {
        for (var i=0; i<linksXML.childNodes.length; i++) {
            var threadsLength = _root.threads.length;
            _root.threads[threadsLength] = new Object();
            _root.threads[threadsLength].lineNumber = _root.lines.count;
            _root.threads[threadsLength].id = String(linksXML.childNodes[i].firstChild);
            _root.threads[threadsLength].percent = 0;
            _root.threads[threadsLength].targetX = 400*Math.random()+50;
            _root.threads[threadsLength].targetY = 150*Math.random()+25;
            if (!isFirst) {
                _root.threads[threadsLength].startX = x;
                _root.threads[threadsLength].startY = y;
                _root.threads[threadsLength].alpha = alpha*0.75;
            } else {
                _root.threads[threadsLength].startX = 500*Math.random();
                _root.threads[threadsLength].startY = 0;
                _root.threads[threadsLength].alpha = 100;
            }
            _root.lines.createEmptyMovieClip("L"+_root.lines.count, _root.lines.count);
            _root.lines.count++;
        }
    };
};

_root.addLinks(true);

_root.onEnterFrame = function() {
    for (var i=0; i<_root.threads.length; i++) {
        _root.threads[i].percent += (1-_root.threads[i].percent)/10;
        _root.lines["L"+_root.threads[i].lineNumber].clear();

        if (_root.threads[i].percent == 1) {
            _root.links.attachMovie("link", "L"+_root.links.count, _root.links.count);
            _root.links["L"+_root.links.count]._x = _root.links["L"+_root.links.count].x = _root.threads[i].targetX;

  59.             _root.threads[i].percent = 1;
  60.         }
  61.     }
  62. };


The problem is that if I try to say this.linksXML or this.x or this.anything in the linksXML.onLoad function it makes 'this' the linksXML object, not the movieclip its in. Is the another way to wirte this? I thought that the function could be written seperately and then envoked by the onLoad event, but that didn't seem to work... maybe I did it wrong.

Anyway any help would be great.
Thx.

Try using this._parent It should be the _parent of the XML object... which sounds like what you are trying to target.

Yeah, I am trying to target the parent of the XML object. If I try to use this._parent it doesn't seem to work. Does the _parent property only work with movieclip objects?

You should probably try the absolute path. like "_root.MC.MC" From my understanding you have written a class and if you reference "this" from within a class you a refering to the class you are calling "this" from. I usually use absolute paths when i have such problems so that the class works no matter where a method is called from because it's calling variables from an absolute location.

Hope it helps
