Command convert zcmd

I have tried to change to zcmd and there is no command, they help me to convert it to zcmd only

public OnPlayerCommandText(playerid, cmdtext[])

{

? ? new string[256], cmd[256], tmp[256], giveplayerid, idx;

? ? cmd = strtok(cmdtext, idx);

? ? if(strcmp(cmd, "/duel", true) == 0)

{

if(PlayerInDuel[playerid] == 1) return SendClientMessage(playerid, -1, "You are already in a duel");

if(DuelPlaceVisit) return SendClientMessage(playerid, -1, "Wait until the duel becomes free.");

tmp = strtok(cmdtext, idx);

? if(!strlen(tmp)) return SendClientMessage(playerid, -1, "duel [player id] [weapon id] [stake]");

? giveplayerid = strval(tmp);

? tmp = strtok(cmdtext, idx);

? if(!strlen(tmp)) return SendClientMessage(playerid, -1, "Usage: / duel [player id] [weapon id] [stake]");

? WeaponDuel = strval(tmp);

? if(WeaponDuel < 0 || WeaponDuel > 42) return SendClientMessage(playerid, -1, "You entered the wrong weapon id. Use id from 0 to 42");

? tmp = strtok(cmdtext, idx);

? if(!strlen(tmp)) return SendClientMessage(playerid, -1, "Usage: / duel [player id] [weapon id] [stake]");

? MoneyDuel = strval(tmp);

? if(MoneyDuel < 100 || MoneyDuel > 1000) return SendClientMessage(playerid, -1, "You entered the wrong bet amount. Use an amount from $ 1 to $ 100,000");

? if(MoneyDuel > GetPlayerMoney(playerid)) return SendClientMessage(playerid, -1, "You are missing a bet. Specify a different amount");

if(MoneyDuel > GetPlayerMoney(giveplayerid)) return SendClientMessage(playerid, -1, "Your opponent is missing a bet. Specify a different amount!");

if(IsPlayerConnected(giveplayerid))

? {

? ? ? if(playerid == giveplayerid) return SendClientMessage(playerid, -1, "You cannot apply this action to yourself.");

? if(PlayerInDuel[giveplayerid] == 1) return SendClientMessage(playerid, -1, "This player is already in a duel..");

? ? GetDuelCreate[giveplayerid] = playerid;

? ? ? ? format(string, sizeof(string), "You have successfully invited player {9DDAF2}%s {FFFFFF} to a duel! Wait for an answer", pNick(giveplayerid));
