Are variables global*? Can you make them global*?




*Global(not true meaning but) = for all players, and if a player logs on it is immeditely synced to them.

Global variables are variables not defined under anything. They always exist.

var
   something //these are global variables.
   something_else
   another_thing

Variables belonging to a type can also be made global:

mob
  var/global/futzes = 0

Okay, but just to clarify, these vars exist on the server and not the client, right?

All variables already exist on the server, with the exception of interface settings (if you consider them "variables"). What do you mean?

If you mean "do all mobs share that same variable", then yes. IE:

mob
  var/global/population = 0
  New()
    ..()
    population++
  Del()
    population--
    ..()
  verb/friends()
    set name = "Do I have any friends?"
    if(population > 1)
      usr << "You have [population-1] friends"
    else
      usr << "You have no friends."


Note that all subtypes of /mob will also share the same variable. So /mob/monsters will contribute to the /mob population, for example.
