you have a code like "I" not "i" or "I(7)".

hmm. yea, you right, i have this command with S[128]

Код:

CMD:runmute(playerid, params[]) {
	if(!gPlayerLogged[playerid]) return SendClientMessage(playerid, COLOR_LIGHTRED, "You need to log in first.");
	if(IsPlayerConnected(playerid))
	{
		new id, reason[128];
		if(sscanf(params, "uS[128]", id, reason)) return SCM(playerid, COLOR_USAGE, "Usage:{FFFFFF} /runmute [playerid] [reason]");
		if(id != INVALID_PLAYER_ID) {

			if(PlayerInfo[id][pReportMuted] < 5) return SCM(playerid, -1, "This player doesn't have mute on /report.");

			PlayerInfo[id][pReportMuted] = 3;
			Update(id, pReportMutedx);

			SCMF(playerid, -1, "You have unmuted %s on /report, reason: %s", GetName(id), reason);

			format(gString, sizeof(gString), "AdmCmd: %s has unmuted %s on /report, reason: %s", GetName(playerid), GetName(id), reason);
			ABroadCast(COLOR_ADMCOMMANDS, gString, 1);

			SCMF(id, COLOR_LIGHTRED, "You have been unmuted on /report by Admin %s, reason: %s", GetName(playerid), reason);
		}
		else return SCM(playerid, COLOR_GREY, "Invalid player id.");
	}
	return 1;
}

but i have another command like this with U and D

Код:

if(sscanf(params, "s[64]U(-1)D(10)", list,id,lines))

and this work perfectly, what's wrong with first command?

or

Код:

if(sscanf(params, "uS(being solved)[128]", id, reason)) return SCM(playerid, -1, "Usage: /re [playerid] [reason]");

The last code snipped you posted raises the same warning? It is in fact the correct syntax for optional string

Nope, just the first code.

Thanks, i solve the problem with your help guys, thanks a lot.

I have another small question, about the same thing

When i use S with round brackets like S(default text)[64] or s(default text)[64] both are correct or only the first?

Re: sscanf warning: No default value found. - Misiur - 26.09.2017

Upper-case character means optional value for which you must provide default value in round brackets. Lowercase means required value, which does not accept default value.
