[UFF]

Use your variable to set in afk and not in afk. I take my own variable as InAFK.

Код:

new bool:InAFK[MAX_PLAYERS]; // my variable for example 

CMD:afktime(playerid,params[]) 
{ 
        new targetid,string[128]; 
        if(sscanf(params, "u",targetid)) return SendClientMessage(playerid,-1,""COL_RED"Cmds: /afktime [playerid]"); 
         if(InAFK[targetid] == false) return SendClientMessage(playerid,-1,""COL_RED"ERROR: This player is not afk!");
        format(string,sizeof(string),""COL_RED"%s is afk for %s seconds.",PlayerName(targetid), Afktime); 
        SendClientMessage(playerid,-1,string); 
    } 
    return 1; 
}
