Most objects are created assuming they are just one of many in the world, a house, a chair, a door...
Some objects need to be idenified as special eg:
create the basket of happiness which show as 'the' not 'a' or 'an'.
Other objects need to have nothing before them, like players. For this we have three 'classes' of object you can use.. which all (currently) display the same way:
create an actor called superman
create an npc called spiderman
create an object called dust
These simply show as 'superman', 'spiderman' and 'dust'
Now we have classes and materials inheriting code, you may find your actor called superman starts reciting Hamplet..
For the record, all players are 'player called {name}' and all commands are 'command called {name}'. The class in both cases is hidden from view but can be refered to to help clarify what you want to do eg:
find the player called wolis
