Remove the for (new i = 0; i < MAX_PLAYERS; i++) because that makes it so everyone gains the score if theres a kill if im right.

pawn Код:

public OnPlayerDeath(playerid, killerid, reason)
{ 
    kill[killerid]++; 
    death[playerid]++; 
    SetPlayerScorekillerid,GetPlayerScore(killerid)+1); //changed playerid to killerid 
    SetPlayerMoney(killerid,GetPlayerMoney(killerid)+1000); //changed playerid to killerid because you have the person who died the cash and points.
    SendClientMessage(killerid,COLOR_YELLOW,"You recieved +1000 money & +1 score."); 
}

if this doesnt work without the (new i = 0; i < MAX_PLAYERS; i++) you could try adding it back but i reccomend trying it without first and with the above code. good luck ;0!
