First add variables like,

pawn Код:

IsPlayerFighting[MAX_PLAYERS];

To check if player is fighting and to block player commands while fighting.
then .
when player /fight . i'll just tp them to the place they will fight(like A Ring)
and under the command i'll

pawn Код:

IsPlayerFighting = 0;

and OnPlayerDeath
check if player is dead
like

pawn Код:

IsPlayerFighting == 1 // checking if player in fight

and give the killer id some money and score :P
