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

visit the sscanf thread to learn more about it

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

@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.
