Dynamically adding objects / datablocks

Hi All.

This thread may belong in a more advanced forum,
but i'll try it out here.

So i'd like to be able to drag-and-drop a resource,
say a .dts file, onto the torque window
and have the object be instanciated in the game.

I've got the drag-n-drop going thru to a script function, eg:
function addFile(%theFile)
{ ... }

How would i have addFile() create a new ItemData datablock ?

Would i need to do something like construct a string
which contains the syntax for a new datablock and eval() the string ?

Also,
am i correct in understanding that i can't do something like this:

//-----------------------------------------------
%shapeFile1 = "some dts file";
%shapeFile2 = "some other dts file";

datablock ItemData(justAStaticShape)
{ };

%newShape1 = new Item()
{
datablock = justAStaticShape;
};
%newShape1.datablock.shapeFile = %shapeFile1;

%newShape2 = new Item()
{
datablock = justAStaticShape;
};
%newShape2.datablock.shapeFile = %shapeFile2;

//-----------------------------------------------

- that is,
i can't use the same datablock for two different .dts files.


many thanks in advance,
Orion
