You're problem seems to be that you're using your "killerid" variables/functions while "killerid" equals INVALID_PLAYER_ID.
This is how it should be:

pawn Код:

public OnPlayerDeath(playerid, killerid, reason)
{
    SendDeathMessage(killerid, playerid, reason);
    if(killerid != INVALID_PLAYER_ID) {
        GivePlayerMoney(killerid, 1000);
        SetPlayerScore(killerid,GetPlayerScore(killerid)+1);
        pInfo[killerid][Kills]++;
    }
    SetPlayerScore(playerid,GetPlayerScore(playerid)-1);
    pInfo[playerid][Deaths]++;
    return 1;
}
