No, he needs to simply pass the parameters that are passed to OnPlayerDeath - like it says on the wiki - :

pawn Код:

SendDeathMessage(killerid, playerid, reason);

You don't need to check whether the killerid is valid or not for SendDeathMessage. INVALID_PLAYER_ID is a valid killerid (it means no killer - suicide).

You never need to check that playerid is valid. Obviously it's valid - someone died, calling OPD.
