SetTagMethod

["Denis Lamarche" <brainwav@...>]

Hi, I am trying to make a table in which I can store information in but also 
use it to access other information in C.  This is what I am trying to do: 
(lua 4.0)

[LUA]
function setanim (receiver, parameter, operator)
 if type(receiver) == "table" then
   --Set_Animation_parameter sets 'C' variables
   return Set_Animation_Parameter(parameter, operator)
 else
   return Old_SetTag(receiver, parameter, operator)
 end
end

function getanim (receiver, parameter, operator)
 if type(receiver) == "table" and parameter ~= "index" and parameter ~= 
"name" then
   --Get_Animation_Parameter() just returns a number from 'C'
   return Get_Animation_Parameter(parameter)
 else
   if parameter=="index" then
     return receiver.index
   end
   if parameter=="name" then
     return receiver.name
   end
 end
end

dis=newtag()
Old_GetTag=settagmethod(dis, "gettable", getanim)
Old_SetTag=settagmethod(dis, "settable", setanim)


function Load_Animation(fname)
temp={}
 temp.index, temp.name=Lua_Load_Animation(fname) --A registered 'C' 
function
 return temp
end

A1_door=Load_Animation("door.dat")
print("Name: -"..A1_door.name.."-  Index: "..A1_door.index)
[End LUA]

for some reason Old_GetTag and Old_SetTag are nil, but I know that the tags 
are being set.  im getanim im trying to return receiver.name if the 
parameter=="name", but this ends up calling getanim again and I guess it 
ends up in a recursive loop and the stack overflows.  What am I doing wrong?
