pawn Код:

public OnPlayerDeath(playerid, killerid, reason)
{
new player[24], killer[24], string[128];
GetPlayerName(playerid, player, sizeof(player));
GetPlayerName(killerid, killer, sizeof(killer));
SetPlayerScore(killerid, GetPlayerScore(killerid) + 1);

format(string, sizeof(string), "%s[%i] has killed %s[%i]!", killer, killerid, player, playerid);
SendClientMessageToAll(0xFF0000FF, string);
return 1;
}

Edit:
I just noticed you want the message "Has been killed by".
Use this code for that message:
