Errors

[Raimis_R]

Hello all i'm today i'm started with lua and i have problem with mysql "defines"

If where are macro function #define ? Because i have error unexpected symbol near "#"

my stuff:

#define MySQL_HOST "localhost" 
#define MySQL_USER "root" 
#define MySQL_PASS "" 
#define MySQL_DATA "fr" 
  
  
mysql = mysql_connect(MySQL_HOST, MySQL_USER, MySQL_PASS, MySQL_DATA) 
  
if (not mysql) then 
    outputDebugString("Unable to connect to the MySQL server") 
    mysql_close(mysql) 
else 
    outputDebugString("Connected") 
end 

Ohh at this moment i'm confused because i think where are somethink like #define

you don't need to define anything, just write

name=var

you should check these

Okey thanks but anyway if where are macro like #define ?

You don't need them. If you don't write a "local" before the name of variable, it'll be global

[Raimis_R]

No you don't understand maybe what i mean just with define you can bind colors like:

#define COLOR_WHITE FFFFFF

It's just example what can i do with #define

There is no way to define a constant in LUA like you can in C. It's really not necessary. In your case, just do:

  
MySQL_HOST =  "localhost" 
MySQL_USER =  "root" 
MySQL_PASS = "" 
MySQL_DATA = 
  

If you want them to be global to all server or client side scripts in this resource. Since this is MySQL stuff though, your probably only going to need it in this script, so:

  
local MySQL_HOST =  "localhost" 
local MySQL_USER =  "root" 
local MySQL_PASS = "" 
local MySQL_DATA = 
  

would be a better solution.
