First of all you should download ZCMD, and SSCANF.
put both of them inside pawno/includes
and SSCANF into plugins depends on your system .so for linux.

after you've done that, at the top of your gamemode add:
#include <YSI\y_ini>
#include <sscanf2>

without these you will not be able to use all sscanf and zcmd methods.
we will use this way:
COMMAND:mycommand(playerid, params[])
or
CMD:mycommand(playerid, params[])

start with

Код:

CMD:announce(playerid, params)
{
   return 1;
}

first make a new string[256];
for our message format.
and playername[MAX_PLAYER_NAME];

new string[256],playername[MAX_PLAYER_NAME];

we want to make a check if the player is admin rcon or not so.

Код:

if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFFFFFF, "You are not admin");

Explanation:
the ! inside IsPlayerAdmin means if he's not admin. don't remove this or else admin will get this message and won't
be able to send an announce.

let's move on.

Код:

CMD:announce(playerid, params[])
{
	new string[256],playername[MAX_PLAYER_NAME];
	if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFFFFFF, "You are not admin");
	return 1;
}

let's make a check if the player doesn't write any message inside the params.

Код:

if(isnull(params))  return SendClientMessage(playerid, 0xFFFFFF, "/announce [text]");

if the params of the command are null <isnull> a return message will popup "/announce [text]"
k time to get the player name for the message.

Код:

GetPlayerName(playerid, playername, sizeof(playername));

playerid - is the playerid.
playername - the variable we made.
sizeof(playername) - the size of the player name, you can use numbers like 265 but i prefer sizeof.

let's move on.
the string of the message will be like that.

Код:

format(string, sizeof(string), "%s : %s", playername, params);

inside format(
string - is the string variable we made
sizeof(string) - the size of the message
%s is the name of the player
%s it's for strings.
%d it's for numbers

%s : %s",
first we have playername then message you can look by here.
playername, params
first playername then params.

then just simple send message to all

Код:

SendClientMessageToAll(0xFFFFFFF, string);

Full command

Код:

CMD:announce(playerid, params[])
{
	new string[256], pName[MAX_PLAYER_NAME];
	if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFFFFFF, "You are not admin");
	if(isnull(params))  return SendClientMessage(playerid, 0xFFFFFF, "/announce [text]");
	GetPlayerName(playerid, pName, sizeof(pName));
	format(string, sizeof(string), "{F2240D}[Admin] %s:{09F7C7} %s", pName, params);
	SendClientMessageToAll(0xFFFFFFF, string);
	return 1;
}

command with sscanf:

Код:

CMD:announce(playerid, params[])
{
	new text[265],string[265],pName[MAX_PLAYER_NAME];
	if(!IsPlayerAdmin(playerid)) return SendClientMessage(playerid, 0xFFFFFF, "You are not admin");
	if(sscanf(params,"s[265]",text)) return SendClientMessage(playerid, COLOR_WHITE,"/announce [text]");
        GetPlayerName(playerid, pName, sizeof(pName));
	format(string, sizeof(string), "{F2240D}[Admin] %s:{09F7C7} %s", pName, text);
	SendClientMessageToAll(0xFFFFFFF, string);
	return 1;
}

Wait wait wait wait wait where the hell did we get ysi/ytimers from? Not everyone will have ysi so tell them to get it. Overall its not too bad of a tut.

[PaulDinam]

they don't need ysi..

[JaKe Elite]

Wa wa wait, what? Including YSI library to just one simple command??
Out of mind?, YSI is not even used in tutorial.

Why is the announce text 265 cells big? You can only have around ~150 characters in a message (different for other resolutions).

You could of done this without sscanf either.
