Optional string (sscanf) - NealPeteros - 16.09.2018

So I wanted to create a /mute command wherein the admin who uses the command may or may not input a reason as to why he'd mute the player. Here's where I got so far

PHP код:
CMD:mute(playerid, params[])
{
    new id, reason[64], time;
    if (sscanf(params, "dS[24]d", id, reason, time))
    {
        SendClientMessage(playerid, -1, "USAGE: /mute [id] [reason (optional)] [minutes]");
        return 1;
    }
    Mute(id, reason, time);
    return 1;
} 
Thing is that when I use it, say for example, like this

Код:
/mute 1 20
/mute - the command

1 - the ID

20 - the minutes

it sends me the

Код:
SendClientMessage(playerid, -1, "USAGE: /mute [id] [reason (optional)] [minutes]");
I wanted the reason to be optional. How u do that?


Oh and it sends me a
Код:
sscanf warning: No default value found.

    if (sscanf(params, "dS(No Reason Given)[24]d", id, reason, time))
    {
        SendClientMessage(playerid, -1, "USAGE: /mute [id] [reason (optional)] [minutes]");
        return 1;
    }
    Mute(id, reason, time);
    return 1;
}

PHP код:
CMD:mute(playerid, params[]) 
{ 
    new id, time, reason[64]; 
    if(!sscanf(params, "uds[64]", id, time, reason)) 
    { 
        if(!IsPlayerConnected(id)) return SendClientMessage(playerid, -1, "disconnected");
        
        Mute(id, reason, time);
        return 1; 
    }
    
    if(sscanf(params, "ud", params[0], params[1])) return SendClientMessage(playerid, -1, "USAGE: /mute [id] [minutes] [reason (optional)]");
    Mute(params[0], "", params[1]); //I recommend using the code that is in "Mute" here.
    return 1; 
}
