SetPVarInt is exactly what I needed! Thanks alot mate!

EDIT:

Here I have a problem. Actually, I did a command /zombie & /human.
By typing one of these commands you will be a zombie & vice-versa.
But now, if I type /human I still can spawn as a Human even if i'm a zombie.
Here's the code:

pawn Код:

public OnPlayerCommandText(playerid, cmdtext[])
{
    if (strcmp("/zombie", cmdtext, true, 10) == 0)
    {
      SetPVarInt(playerid, "IsZombie", 1);
      ResetPlayerWeapons(playerid);
      SetPlayerInterior(playerid, 0);
      SetPlayerPos(playerid,-2768.17,-715.08,65.84);
      SendClientMessage(playerid,0x0000BBAA, "Need tips? Type /zombiehelp!");
      GivePlayerWeapon(playerid, 33, 150);
      SetPlayerSkin( playerid, 287 );
      return 1;
    }
    
    if (strcmp("/human", cmdtext, true, 10) == 0)
    {
        ResetPlayerWeapons(playerid);
        SetPlayerInterior(playerid, 0);
        SetPlayerPos(playerid,-2768.17,-715.08,65.84);
        SendClientMessage(playerid,0x0000BBAA, "Need tips? Type /humanhelp!");
        GivePlayerWeapon(playerid, 33, 150);
        SetPlayerSkin( playerid, 17 );
        return 1;
    }
    else if(GetPVarInt(playerid, "IsZombie") == 1)
    {
        SendClientMessage(playerid,COLOR_RED, "You are a zombie, you canno't switch!");
        return 1;
    }
    return 0;
}
