I have a table used as a class:
> table.foreach (GenericDesk,print);
sy 6
dir 0
event_look function: 0039e460
event_hit function: 0039e580
......
then I do
>obj=GenericDesk:new();
where
function GenericDesk:new (obj)
obj=obj or {};
setmetatable (obj,self);
self.__index=self;
return obj;
end
which I copied from the 'programming in lua' book,
16.1
then I do
>table.foreach (obj,print);
and I get a void list.
I was expecting the same result as the initial
table.foreach (GenericDesk,print) action. I think that
(remember, I'm a newbie ;) ) that the parameters are
there "by default", but they are not shown.
I'd like to know if there's any way to show them, as
I'm retreiving a list of functions which start with
"event_" to know which events are available for that
object.
I think I should search on obj.__index, but I'm not
sure if it's correct.
However, if I look at the object and the __index I can
get duplicate event functions, as objects can have
overloaded event functions.
Which should be the cleanest way to get a list of
"event_" starting functions of an object with a parent
class?
TIA
Kak.
