Re: [Flashcoders] Dynamic class creation
Or just use mx.utils.ClassFinder.
var classname:String = "com.mosesSupposes.fuse.Fuse";
var FuseClass:Function = mx.utils.ClassFinder.findClass(classname);
fuse = new FuseClass();

RE: [Flashcoders] Dynamic class creation-thoughts?
Nice job for creating dynamic linked library in flash, thanks to Farid and
Scott. Of course compiled clips and components do the same, but using dlls
gives us the ability to load classed whenever they are needed and not just
including them all in the first frame!
I was wondering if it is possible to load a class with a given string using
pure ActionScript and I guess it's not. Well that's not an issue in flash and I
was wrong to compare Java and flash in this case because in Java classes are
compiled in separate .java files and it takes time for an application to load
them all at startup, hence manually loading classes (as I described in my other
post) can improve application performance, but since in flash all classes are
embedded in a single compiled .swf file they are available when swf is loaded

Re: [Flashcoders] Dynamic class creation-thoughts?
I may be idiot, but how would you generate a menu's items given
dynamic data ???
I cannot but see dynamic instantation, can I ?
same for games, same for MP3 players (and video), same for whatever
almost anything ?
cedric
I don't see the ish. If you're making a shooter game and have
classes for enemies and classes for bullets, how would you put that
into effect WITHOUT dynamic instantiation. I'm a hell of a lot more
concerned with the idea of dynamic definition.

Re: [Flashcoders] Dynamic class creation-thoughts?
I don't see the ish. If you're making a shooter game and have classes
for enemies and classes for bullets, how would you put that into effect
WITHOUT dynamic instantiation. I'm a hell of a lot more concerned with
the idea of dynamic definition.

thank you all, i've already made it!
var str:String = 'test1.test2.ClassC';
var arr = str.split('.');
var variable = _global;

sorry, should be:
new className()
make sure pkg1 has classes you would like to be compiled in swf or
use exclude xml file

when i got class e,gpkg1.pkg2.pkg3.className
i can make new instance in this way
new pkg1.pkg2.pkg3.className()
but i want to make it from string
this dont work of course
_global['pkg1.pkg2.pkg3.className']();
but this work:
_global['pkg1']['pkg2']['pkg3']['className']();
can this done automatcally? i want jsut read string from XML and
create new class instance,
but i cant do it now.
Any help is appreciated :)

Re: [Flashcoders] Dynamic class creation
This should do the job.
1. ClassFactory to create classes specified by strings.
class ClassFactory
{
public static function create(className:String):Object
{
// Split the class name into its parts
var parts:Array = className.split(".");
// a variable to build a reference to the class
var classRef:Object = _global;
// Iterate over the parts, digging deeper each time
// into the namespace heirarchy
for(var n=0;n < parts.length;n++)
{
classRef = classRef[parts[n]];
}
// Check that the class exists
if(classRef == undefined)
{
throw new ClassCreationException("Class not found : " +
className);
}
else
{
return new classRef();
}
}
}
2. The Class Creation Exception, nothing special :)
class ClassCreationException extends Error
{
public function ClassCreationException(msg:String)
{
message = msg;
}
}
and some test code to check it works :
var className:String = "com.test.MyClass";
import com.test.MyClass;
var c:MyClass;
try
{
var c:Object = ClassFactory.create(className);
}
catch(e)
{
trace(e.message);
}
of course, you need the reference to the class you want to create somewhere or
the compiler wont include it when it builds the swf, hence the
var c:MyClass line.
for me thats the worst part of the whole thing, but theres ways you can organise
this, e.g. a simple include that just lists the declarations you will need
#include "forceIncludes.as"
which just contains a list of the references
im sure there are other solutions to this little problem, if anyone else has any
bright ideas id like to know.
Of course, the other part of this is that the class factory can only return
objects that are typed as 'Object' so you lose quite a bit of type safety like
this, unless of course you are creating objects that all conform to a specific
interface. You might want to modify the class factory to add methods that return
particular types of objects with a return type set to their common interface. It
depends on what your requirements are really on how you architect this part.
hope that all makes sense.
thanks,
Martin

I've done exactly that using eval() before. Give it a try.
