Optional Integers? SSCANF. - Dokins - 24.01.2012

pawn Код:

if(sscanf(params, "uDDs[128]", giveplayerid,hours,days, reason)) return SendClientMessage(playerid, COLOUR_GREY, "Usage: /tban [player id] [hours] [days] [reason]");

It returns the message although I stated the 2 are optional (hours and days)

pawn Код:

if(sscanf(params, "uD(0)D(0)s[128]", giveplayerid,hours,days, reason)) return SendClientMessage(playerid, COLOUR_GREY, "Usage: /tban [player id] [hours] [days] [reason]");

This will automatically return 0 if none are entered.

Yes, I've added the D(0)'s and it still returns the client message. I'd like to only to be able to select one parameter without it returning the message.

You will probably have to reorder your command syntax in order for this to work.. but,

As far as I know, you'd have to do a separate thing like:

pawn Код:

if(sscanf(params, "uD(0)D(0)s[128]", user, date1, date2, string)) 
{
if(isnull(date1) { date1 = ..; }
else if(isnull(date2) { date2 = ..; }
}

and go on like that, although, I definately could be wrong. Just throwing ideas out there.

Ah, I knew it. ******, could you show me how to do it with a custom separator by any chance?
