how to do optional parameters in sscanf?

like typing /kick will send "Usage: /kick [id] [reason]"

but typing /kick 1 will be successful even without reason

[rappy93]

pawn Код:

if(sscanf(params,"d", playerid)) return SendClientMessage(playerid, "/kick [target id]");

Think this might do it.

This can help.
If you want to add a reason to it use this:

pawn Код:

if(sscanf(params, "us[128]", tID, reason)) return SendClientMessage(playerid, /*COLOR HERE*/, "* [USAGE]: /kick [playerid/PartOfName] [Reason]");

I replaced the "d" with "u" so you can type a part of the players name or his ID.
"s" stands for string, that means that it's a message, in this case: your reason.
"[128]", behind the "s" is the maximum length your reason can have.

If you want to make your reason optional, use this:

pawn Код:

if(sscanf(params, "uS(No Reason)[128]", tID, reason)) return SendClientMessage(playerid, /*COLOR HERE*/, "* [USAGE]: /kick [playerid/PartOfName] [Reason]");

Make sure you have a local variable. Example:

pawn Код:

new reason[128];

Edit:
I forgot to mention that "tID" is the targetid, you have to make a local variable for that one too.

pawn Код:

new tID;

[jamjamnewbie]

does this work?

Код:

CMD:kick(playerid, params[]) {
     new targetid, reason[128];
     if(sscanf(params, "u", targetid)) return SendClientMessage(playerid, COLOR_HERE, "Usage: /kick [id] [reason]");
     else if(!sscanf(params, "u", targetid)) {
          //rest of code here
          SendClientMessageToAll(COLOR_HERE, "BLABLABLA has been kicked <> Reason: No reason specified");
     } else if(!sscanf(params, "us[128]", targetid, reason)) {
          //rest of code here
          SendClientMessageToAll(COLOR_HERE, "BLABLABLA has been kicked <> Reason: the reason here");
     }
     return 1;

This is an example of how it should be done:

pawn Код:

CMD:kick(playerid, params[])
{
    new targetid, reason[128], string[128], aname[MAX_PLAYER_NAME];
    if(sscanf(params, "uS(No Reason)[128]", targetid, reason)) return SendClientMessage(playerid, 0xAFAFAFAA, "Usage: /kick [id] [reason]");
    else
    {
        GetPlayerName(playerid, aname, sizeof(aname));
        //rest of code
        format(string, sizeof(string), "* Administrator %s has kicked %s, reason: %s", aname, targetid, reason);
        SendClientMessageToAll(COLOR_HERE, string)
    }
    return 1;
}

does the "S(no reason)" in sscanf have to be capital? and also i have to include that part within the parenthesis?

[Konstantinos]

Use optional string as Bible showed you. You also don't need to check anything because "reason" array stores the text whether the input was given or not.

pawn Код:

CMD:kick(playerid, params[])
{
    new targetid, reason[64];
    if (sscanf(params, "rS(No reason specified)[64]", targetid, reason)) return SendClientMessage(playerid, COLOR_HERE, "Usage: /kick [id] [reason]");
    //rest of code here
    new msg[144];
    format(msg, sizeof (msg), "%s has been kicked <> Reason: %s", ..., reason);
    // ... is the argument for the name, modify it accoding to the code you have..
    SendClientMessageToAll(COLOR_HERE, msg);
    return 1;
}

Yes, the text should be inside parentheses and it doesn't matter about the letter case (lower/upper).

The capital "S" indicates that it's optional. "(No reason)" is the message that should be shown if there is no reason specified by the player.

EDIT:

Konstantinos gave you a great explanation why you should use the text between the parentheses.
