How to replicate this in MTA?

[Cassandra]

Does anyone know how to replicate this in MTA?

- Basic LUA knowledge and..

fileCreate 
fileOpen 
fileRead 
fileWrite 
fileClose 
outputChatBox 

If you just don't have enough patience to create a basic interpreter to make something like INI files, use XML functions instead (if you're going to store a small amount of things).

I want to know the LUA knowledge of doing that. For example, multi-dimensional array and normal arrays which reference id and stuff. Thanks for your response.

I guess that would explain everything. If you need to know something more, you can search on that website. If you don't find something, just come back.

Do you know how to do ENUMERATORS on LUA?

[Anderl]

That is not natively possible in LUA, but you can emulate it.

Could you show an example?

[Anderl]

function enum ( vars ) 
    assert ( vars, "no values in enum declaration" ); 
     
    for enum_name, int in pairs ( vars ) do 
        _G[enum_name] = int; 
    end 
end 
  
--Example: 
enum { COLOR_A = 1, COLOR_B = 2, COLOR_C = 3 }; 
  
local someValue; 
function setValue ( str ) 
    if ( str:find ( "a", 0 ) ) then 
        someValue = COLOR_A; 
    elseif ( str:find ( "b", 0 ) ) then 
        someValue = COLOR_B; 
    elseif ( str:find ( "c", 0 ) ) then 
        someValue = COLOR_C; 
    end 
end 
  
setValue ( "b" ); 
  
--lets see: 
if ( someValue == COLOR_A ) then 
    outputChatBox ( "COLOR_A" ); 
elseif ( someValue == COLOR_B ) then 
    outputChatBox ( "COLOR_B" ); 
elseif ( someValue == COLOR_C ) then 
    outputChatBox ( "COLOR_C" ); 
else 
    outputChatBox ( "Something has gone wrong." ); 
end 

But you'll still need to add 1, 2, 3, 4, etc. in each value unless you use strings instead of just COLOR_A, COLOR_B and you'd also need to change the for loop in the "enum" function, unlike C/C++ where it automatically sets a number to each value (in order).
