Try using

PHP код:

   CMD:afk(playerid,params[])
    {
        new targetid, string[128];
        if(sscanf(params,"d",targetid, targetid)) return SendClientMessage(playerid, -1,"CMD: /afk [ID]");
          if(!IsPlayerConnected(targetid)) return SendClientMessage(playerid,-1,""COL_RED"Player is not online!");
        if(IsPlayerMoving(targetid) == 0)
        {
            format(string, sizeof(string), "%s is AFK for %d seconds",PlayerName(targetid), AFKTime[targetid]);
            SendClientMessage(playerid,-1,string);
        }
        else
        {
            SendClientMessage(playerid,-1,"This player is not AFK");
        }
        return 1;
    } 


better than params[0]
