Well you want to do you foreach() loop in OnPlayerDisconnect() actually also you don't if(!IsPlayerConnected(i)) when using foreach. Also this assignment is incorrect.

pawn Код:

killerid = pKiller[playerid];

//should be
pKiller[playerid] = killerid;

But it also looks like your revenge system is not what I expected so you might have to explain a bit more.
