-*- Ping Faker 1.5 -*-
----------------------
~~~~~~~~~~~~~~~
- 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
having a specific IP/SteamID. 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 [0/1] - Enable/disable ping faking
* pingfake_ping [1337] - The ping you want displayed (min: 0 // max: 4095)
* pingfake_flux [0] - Fake ping fluctuation amount (0 = none)
* pingfake_target [0/1] - Whether to display fake ping to its target too
* pingfake_bots [0/1/2] - Affect bots too (set to 2 for bots ONLY setting)
* pingfake_multiplier [0.0] - Set this to have the fake ping be a multiple
of the player's real ping instead of fixed values (0.0 = disabled)
* pingfake_fileonly [0/1] - Enable this to fake pings ONLY for players
listed on the .INI file
Note: changes to these will take effect after a new round.
~~~~~~~~~~~~
- Commands -
~~~~~~~~~~~~
* amx_fakeping <target> <ping>
- Toggle fake ping override for player (use -1 to disable)
You can also have players automatically get fake pings according to IP/SteamID
by editing the "fakepings.ini" file in your configs folder.
~~~~~~~~
- ToDo -
~~~~~~~~
* Fix this to send a single SVC_PINGS message, using the real
arguments used by the HL engine, which can be found here:
http://wiki.amxmodx.org/Half-Life_1_Engine_Messages#SVC_PINGS
~~~~~~~~~~~~~~~~~~~
- 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 all of the pings in a single
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).

- Changelog -
~~~~~~~~~~~~~
* v1.0: (Feb 23, 2009)
- Public release
* v1.1: (Feb 23, 2009)
- Managed to send up to 3 pings on a single message,
thus reducing bandwidth usage by 26%
* v1.2: (Feb 23, 2009)
- Added fake ping fluctuation and affect bots settings
* v1.2a: (Feb 24, 2009)
- Fixed is_user_bot flag not being reset on disconnect
* v1.3: (Feb 24, 2009)
- Added admin command to manually toggle fake ping for players
- Added feature to automatically load fake pings from file
* v1.4: (Mar 15, 2009)
- Added feature (+CVAR) to have the fake ping be a multiple
of the player's real ping
* v1.5: (Jun 06, 2011)
- Fixed plugin so that it works on all HL mods
- Removed CVAR pingfake_flags (not really needed anymore)
- Added feature (+CVAR) to have the plugin fake pings ONLY for
players listed on the .INI file
- Fixed fake pings overriden after DeathMsg/TeamInfo events in CS
