Hi Danny, The idea of the import statement is to specify which class namespaces you want to use. For example, there could be multiple packages that contain a class named "Danny": com.kodicek.Danny com.day.lewis.Danny
If you wanted to use the first class, you'd need to write all of it every time you wanted to instantiate it, like this: myClass = new com.kodicek.Danny () myClone = new com.kodicek.Danny () But to make it easier, you can import it at the top of the containing class: import com.kodicek.Danny; Having imported it, you let the containing class know which Danny you want to be using, so then you can instantiate it without appending the full package name each time: myClass = new Danny() myClone = new Danny() You can also use: import com.kodicek.*; And that would import all the classes in the specified package, saving you the hassle of importing them one by one - but Flash will only compile the class or classes you end up using in the script, keeping the swf size just as small as if you'd used "import com.kodicek.Danny". I hope that wasn't over-explaining: I know you're not exactly a newbie to programming ;) Karina > -----Original Message----- > From: Danny Kodicek [mailto:[EMAIL PROTECTED] > Sent: 19 March 2007 11:45 > To: [email protected] > Subject: RE: [Flashcoders] Create an object by name > > > Hello Danny, > > This short snippet should return you the constructor: > > > > /** Returns the class constructor from a dotted path. > > * e.g. [EMAIL PROTECTED] var > > cons:Function=getConstructorFromPath("com.pkg.fred.Bucket"); } > > */ > > public static function > > getConstructorFromPath(classPath:String):Function > > { > > var arr:Array=classPath.split("."); > > var obj:Object=_global; > > for(var i:Number=0;i<arr.length;i++) > > { > > obj=obj[arr[i]]; > > } > > return Function(obj); > > } > > > > Then just do var obj:Object=new cons(); > > Thanks, Ian.
