If you want a kill/time ratio, you can do that probably with scripting...
not sure if this is right:
var
MapStart: cardinal;
procedure OnMapChange(NewMap: string);
begin
MapStart := GetTickCount();
end;
function OnPlayerCommand(Id: byte; Text: string): boolean;
begin
if (LowerCase(Text) = '/ktr') then SayToPlayer(Id, 'Your kill/time ratio is: ' + FloattoStr(GetPlayerStat(Id, 'Kills') / (GetTickCount() - MapStart)));
end;
ofc caps would also need to be taken out, and scripted points given to players;
unit of time is ticks, can be converted... 60 ticks = 1 second so the number may be small
if you want per minutes, multiply that number by 3600
rounding it may also be a good idea...
