This is a modified version of a class made by Ted Patrick (MCE). Use make()
to create an empty movieclip and bind it with a class. Use attach to attach
one from the library and do the same.
Mind the linebreaks...
class MCUtils {
private static var COUNT:Number = 0;
private static var ext:String = "";
public static function make(scope:MovieClip, name:String, depth:Object,
className:Object, args:Array, initObj:Object) {
var clip:MovieClip = MovieClip.prototype.createEmptyMovieClip.apply(scope,
[name != null ? name + ext : COUNT++ + ext, depth != null ? Number(depth) :
scope.getNextHighestDepth()]);
if(initObj) for (var p:String in initObj) clip[p] = initObj[p];
if(className) {
clip.__proto__ = className["prototype"];
className.apply(clip, args ? args : []);
}
return clip;
}
public static function attach(scope:Object, link:String, name:String,
depth:Object, className:Object, args:Array, initObj:Object) {
var clip:MovieClip = MovieClip.prototype.attachMovie.apply(scope, [link,
name != null ? name + ext : COUNT++ + ext, depth != null ? Number(depth) :
scope.getNextHighestDepth(), initObj]);
if(className) {
clip.__proto__ = className["prototype"];
className.apply(clip, args ? args : []);
}
return clip;
}
}
