-*- Ping Faker 1.0 -*-
----------------------
~~~~~~~~~~~~~~~
- Description -
~~~~~~~~~~~~~~~
This plugin can fake the display of a player's latency (ping) shown on
the scoreboard. Unlike the "fakelag" command, it does not affect the
player's real latency in any way.
You can have all players report the same ping, or only fake it for those
who have a specific admin flag. This last feature is especially useful
when running a dedicated server from your own computer, when you don't
want people to guess you're an admin/owner by looking at your low ping.
~~~~~~~~~
- CVARS -
~~~~~~~~~
* pingfake_enable [1/0] - Enable/disable ping faking
* pingfake_ping [1337] - The ping you want displayed (min: 0 // max: 4095)
* pingfake_flags [""] - Affect players with these flags only (empty = all)
* pingfake_target [1/0] - Whether to display fake ping to its target too
Note: changes to these will take effect after a new round.
~~~~~~~~
- ToDo -
~~~~~~~~
* Find out exactly what the arguments for the SVC_PINGS message mean, so
as to send a single message with all pings on it and reduce bandwidth
usage (does the HLSDK say anything about those?)
~~~~~~~~~~~~~~~~~~~
- Developer Notes -
~~~~~~~~~~~~~~~~~~~
The SVC_PINGS message can't be intercepted by Metamod/AMXX (it is purely
handled by the engine) so the only way to supercede it is to send our own
custom message right after the original is fired. This works as long as
the custom message is parsed AFTER the original. To achieve this here, we
send it as an unreliable message (cl_messages 1 helps see arrival order).
The next difficulty is in figuring out what the message arguments are.
For this I did some trial and error until I finally got it working, though
in a really odd way. I also can't seem to send more than one ping on the
same message without getting weird results or triggering heaps of message
parsing errors (namely svc_bad).
A final consideration is bandwidth usage. I found out (with cl_shownet 1)
the packet size increases by 102 bytes when the original SVC_PINGS message
is sent for 32 players. Sending our own message right after means the size
will grow even larger, so we should only send the message when absolutely
needed. In this case that's once every client data update (any less often
than that and the ping wasn't properly overridden sometimes).
