Example
procedure OnPlayerCommand(Player: TActivePlayer; Text: string);
begin
// Assuming config Sandboxed=2 (default)
Delete(Text, 1, 1); // remove command's slash
try
if FileExists('~/' + Text + '.ini') then
Player.WriteConsole('Yup, config for that map exists', $FFFFFFFF);
else
Player.WriteConsole('Sorry, this config for this map doesn''t exist', $FFFFFFFF);
except
Player.WriteConsole('Wrong path (you added ../ a few times, didn''t you?)', $FFFFFFFF);
end;
end;
