Re: [Flashcoders] Flash equivalent of a Java class loader

2006-01-05 Thread August Gresens 
Another related question -  now that we can instance a class specified in an
XML document, how can
we dynamically associate this class with a MovieClip instance? It is my
understaning that Object.Register
class associates a class with a movieclip symbol (not an instance).

Thanks,

August

[Flashcoders] Flash equivalent of a Java class loader

2006-01-04 Thread August Gresens 
Hello

We're new to flash, migrating over from Director. We're trying to implement
a Java style class loader in Flash, but we are having some difficulty doing
this.

This is what we  are trying to do:

1. Create an XML document with elements specifying the name of the class, a
movieclip instance and and some initialization parameters.

for example:

object class=com.blackhammer.test.TestClass name=testClassInstance1
clipName=myTestClip
param name=param1 value=1 type=int/
/object

2. On startup, the Flash movie parses the XML file, instancing a class
corresponding to the string name specifiied in the XML (associating it with
the specified MovieClip), and populates the newly created object with the
parameter values specified in the XML.

When we attempt to do this using RegisterClass, however, it appears as
though the class name cannot be passed in as a string.

This works:

Object.RegisterClass(myClipSymbolName, com.blackhammer.test.TestClass);

This doesn't:

Object.RegisterClass(myClipSymbolName, com.blackhammer.test.TestClass);

Any clues?

Perhaps there is a more elegant way of doing this anyway, since
RegisterClass seems to associate all instances of myTestClip (the symbol)
with the specified class. What we'd like to do is associate an instance of a
class with an instance of a movieclip.
