Question about Variables - CoDeZ - 02.08.2012

Hello guys , if i have a variable under ZCMD for example

pawn Code:

CMD:duel(playerid,params[])
{
      new Money,targetid[24];
      if(sscanf(params,"ud",targetid,Money)) return SendClientMessage(playerid,-1,"usage:blablabla");
      return 1;
}
OnPlayerDeath(playerid,killerid,reason);
{
     if(killerid!=INVALID_PLAYER_ID)
     {
        new Money;
        givePlayerMoney(killerid,Money); 
     }
     return 1;
}

question is , will the variable value will get saved and if i typed for example:

Code:

/duel 0 500

Will the variable get saved and give 500$ to killer id?

What's the difference then?
static remembers the value and saves it?

edit: nope, I got them wrong :X you have to create global variables

Targetid is a variable in your code, so change:

pawn Code:

Targetid[24];

to:

pawn Code:

Targetid;

If your variable is inside your command (as you've showed to us) Than it won't be a global variable that you can actually use in your script.
In the top of your mod, under all of your includes, defines, etc... Where you probably have variables there, just add the "Money" variable, and then you'll be able to use it in your whole script, without using stating it as a new ("new") variable each time

Alright thanks. RPed+.

Thank you , i'll add them in the top of my script because i've got a lot of variables though , converting them to static would take some time.

Mr SEnergy, you just won the contest for most retarded sentence in the history of the Internet!

https://sampwiki.blast.hk/wiki/Scripting_Basics#Scope - read this. Once, twice, or even infinite times, I don't care - just as much as you need to understand basic concept of scope and the word "local". When you get this right, you can start helping others.
