Functions - Game Engine Capabilities

[nemesis567]

I'm wondering if some functions exist, because I can't find them.

So, tell me if they exist:

-Create a static object/Area Via Script;
-Disconnect a body from a rope/CXonnect a body to a rope;
-Change a determined entity model Via script;


Now I'd like to know if the game engine allows the following procedures:

-Create a friendly NPC;
-Create a new lantern type item(without replacing lantern nor messing up with the sys files)
-Create a moveable object(And object that moves as specified in the script with the speed specified in the script, in the direction specified in the script);
