Код:

dcmd_SendAllTheirNames(playerid,params[])
{
    #pragma unused params
    for(i=0; i<MAX_PLAYERS; i++)
    {
       // code here...but explain me this...

This will loop around all players, where "i" is their ID.

i got it now...its like this u can use something else ex:

Код:

#define SERVER_MAX_PLAYERS 20 // example 20 is my server's max players...

then in the cmd :

Код:

for (new i=0; i<SERVER_MAX_PLAYERS; i++)
{
   if (IsPlayerConnected(i))
   {
     SendClientMessage(playerid,0xAA000AA,"HAHA!");
   }
}

that wood work, right? ( if 20 wood be my max player setting )

SendClientMessage(i, ...);
It will send it for players from 0 to 19.

Then he won't see the message because you've limited your loop to 20 players.

il put 21 then that wood loop 20 players!

This will loop for 21 players - IDs: 0-20

pawn Код:

for(new i = 0; i < 21; i++)
{
  if(IsPlayerConnected(i)) SendClientMessage(i, 0xAA000AA, "HAHA!");
}

This will loop for 22 players - IDs: 0-21

pawn Код:

for(new i = 0; i <= 21; i++)
{
  if(IsPlayerConnected(i)) SendClientMessage(i, 0xAA000AA, "HAHA!");
}

The only difference in this code from the first one is that i've used <= so this means if i is smaller than 21 or equal to 21.

And i suggest to you to use ******'s foreach include - it's faster than normal for loop and you don't have to use IsPlayerConnected function because foreach already has this check in its code.

foreach include - http://forum.sa-mp.com/index.php?topic=117573.0

Example with foreach:

pawn Код:

foreach(Player, i) SendClientMessage(i, 0xAA000AA, "HAHA!");
