[Raimis_R]

pawn Код:

new
    Float:Pos[ 3 ]
;
GetPlayerPos( playerid,Pos[ 0 ], Pos[ 1 ], Pos[ 2 ] );

for( new i = 0; i != MAX_PLAYERS; i++ )
{
    if( !IsPlayerConnected( i )) continue;
    if( IsPlayerInRangeOfPoint( i,Radius,Pos[ 0 ], Pos[ 1 ], Pos[ 2 ] ) )
    {
        SendClientMessage( i,COLOR,"TEXT" );
    }
}

Or like i said use LimitGlobalChatRadius( Radius ); and put in OnGameModeInit
