The XML definition for this component allows you to define a script object, a con-
structor, and a destructor. The script object is the name of a Lua variable where a Lua
instance of this object will live. The constructor is the name of a Lua function that is
called when the actor has been created, while the destructor is the name of a Lua
function that is called when the actor is destroyed. Both the constructor and destruc-
tor Lua functions are of the form
func(scriptObject)
, where
scriptObject
is
the Lua instance of this component.
Since there
m not going to cover it in depth. This class
follows the same basic pattern the others have. The idea behind this class is that it
represents the actor as far as Lua is concerned. All actor-specific functions should
