Use the 'invite' command to invite another player to your party.
If that player accepts, via the 'acceptinvite' command, they and any
splitscreen players on their machine will be added after the players
in your party. They may also use the 'rejectinvite' command.
Use the 'leaveparty' command to leave a party. You and any splitscreen players
on your machine will be removed from the party. Players after you will be
shifted to take your place on the splitscreen.
This is accomplished by simply preserving
the player's body after disconnecting.
Bodies will despawn after the number of minutes
specified by the "rejointimeout" console variable (float).
A value of 0 disables the feature completely.
Clients rejoining are identified by their IP address,
and may rejoin even if the server is full or joins are disabled,
for as long as their body remains.
From a technical standpoint, when the user disconnects,
the player they were controlling does not leave,
the underlying player_t just keeps working normally,
except it does not receive any input anymore.
When the user reconnects, they are simply "relinked"
to their player_t.
Those "soulless" players can be identified through
their "quittime" field, which is the number of tics
elapsed since the user disconnected, or zero
if still connected. "quittime" is exposed to Lua.
* Update the function signature of P_MixUp to accomodate both it and drawangle instead of doing it outside of the function.
* If the player is spawning from the start of the stage and it's from the ceiling, be in fall frames as requested (resolves#191).
Someone thought it was a good fucking idea to make logins NetXCmds. NetXCmds
are sent to everyone however. Thankfully logins are two passes. And the second
pass uses a salt based on the playernum. Therefore, in order to actually make
use of the final hash, you'd have to be the same playernum as who originally
sent it. Still a stupid exploit.
P.S. The netcode is LOL XD by VincyTM -Telos
