Per example...

1  class ObjectClass
2  {
3  	int Health = 100;
4  } 
5 
6  typename t; // t is null
7  t = ObjectClass;
8  string classname = TypeName(t); // returns "ObjectClass";
9  t = Type(classname); // returns ObjectClass typename too

Line 8 throws "Undefined function TypeName", I've searched the codebase and don't find any such proto function.

Think this should be

8  string classname = t.ToString(); // returns "ObjectClass";

After that change, I now get error line 9 "Too many parameters for 'Type' method". Class::Type() takes no parameters.

My aim here, if it's by some other method, is to instantiate my classes by string name

I'm guessing this is done via something like that. But I already know I'm barking up the wrong tree because this throws "Unknown type 't'" line 2

1  typename t = ObjectClass;
2  t myt = new t();
3  Print(myt.Health);
