Command and Parameters - HidroDF - 02.01.2017

Hello, I'm trying to make a command with multiple parameters but, each case is different.

I'm creating the /ochat command and I need to use it with one or two parameters. There are two options: invite and close. The close parameter doesn't have any extra parameter just /ochat close and chat will close. But with invite I need to add a parameter (playerid) and I don't know how I can use first one parameter to detect where IF statement I have to go and then check if the player has entred a second parameter, in case of "invite".

I'm making this:

Код:

CMD:ochat(playerid, params[])
{
    new param[10];
    new id;
    if(sscanf(params, "s", param)) SendClientMessage(playerid, -1, "Use: /ochat [invite | close]");
    if(strmatch(param, "invite"))
    {
        if(sscanf(params, "sd", param, id)) return SendClientMessage(playerid, -1, "Use: /ochat invite playerid");
        SendClientMessage("OK");
	}
	else if(strmatch(param, "close"))
	{
        SendClientMessage("CLOSE");
	}
	else
	{
	    SendClientMessage(playerid, -1, "Options: invite + playerid or close");
	}
	return 1;
}

But don't work.

Anyone can help me? Thanks!

as suggested by GoldenLion, use "U" instead of "I" i was too quick

You can use "D" or "I" for an optional integer, not sure if you can do it with the player specifier like this: "U", but you should try.
But this is what it would look like with an integer:

Код:

new item[10], playerid;

if (sscanf(params, "s[10]D(INVALID_PLAYER_ID)")) return SendClientMessage(playerid, -1 "usage...");

if (!strcmp(item, "invite"))
{
    if (playerid == INVALID_PLAYER_ID) return SendClientMessage(playerid, -1 "usage...");

    //do whatever you want with the playerid here
}
else if (!strcmp(item, "close"))
{
    //that closing stuff
}

EDIT: CutX was faster

Re: Command and Parameters - Spmn - 02.01.2017

@GoldenLion, there's a little mistake in your code at sscanf part. INVALID_PLAYER_ID will get treated as a string, so you should have used a negative default ID as CutX did, or use the stringize operator:

Код:

if (sscanf(params, "s[10]D(" #INVALID_PLAYER_ID ")")) return SendClientMessage(playerid, -1 "usage...");

You should use strcmp with its length parameter to check what the first option is.

After that and a match was found, use sscanf with its ignore feature ("{s[7]}" - for your case) followed by other specifiers.

And you're pretty much set. The only con about this is that you will have to place the strcmp if-thens in a order where none conflict (e.g. helpme should go before help). You could avoid this tiny issue by using sscanf at the start (s[]s []), you'll have no use for the ignore feature however. Use the argument given by sscanf.
