This file is intended as a set of exports for an NQ-based engine.
|
||
|
|
This is supported _purely_ for clients, and will not work for servers (safe no-op).
|
||
|
|
|
||

[EndUser] how to use:
|
||
|
|
to join a qw server: connect "udp:127.0.0.1:27500"
|
||
|
|
to watch a qtv stream: connect "tcp:3@127.0.0.1:27599" (where '3' is the streamid)
|
||
|
|
to watch an mvd demo: connect "demo:blahblah.mvd" - the demo will be loaded from $WORKINGDIR/qw/demos/ - note that $WORKINGDIR is NOT always the same dir
|
||
|
|
as your engine is running from. The -basedir argument will break it, or engines that hunt down a 'proper' installation of quake instead.
|
||
|
|
|
||
|
|
|
||
|
|
[Developer] how to incorporate into an nq engine:
|
||
|
|
copy this file (net_qtv.h) into your source directory, next to your other net_*.h files
|
||
|
|
load up net_win.c
|
||
|
|
find the #include "net_wins.h" line.
|
||
|
|
dupe it, call it net_qtv.h
|
||
|
|
find the net_landrivers array. Dupe the first block, then edit the first block to be all QTV_foo functions.
|
||
|
|
bump net_numlandrivers.
|
||
|
|
For non-window operating systems, you'll need to do the same, just figure out which net_win.c equivelent function it uses first. :P
|
||
|
|
certain engines may do weird things with the port. probably its best to just use Cmd_Args() for the connect command instead of Cmd_Argv(1), and to add
|
||
|
|
port parsing to XXXX_GetAddrFromName instead of messing around with port cvars etc and ruining server configs.
|
||
|
|
If your engine already has weird port behaviour, then its entirely your problem to fix. :P
|
||
|
|
You probably want to tweak your menus a little to clean up the nq/qw/qtv connection distinctions.
|
||
|
|
If you do want to make changes to libqtv, please consider joining the FTE team (or at least the irc channel) in order to contribute without forking.

[Developer] how to compile libqtv:
|
||
|
|
cflags MUST define 'LIBQTV' or it won't compile properly.
|
||
|
|
The relevent exports are all tagged as 'EXPORT void PUBLIC fname(...)' (dllexport+cdecl in windows), feel free to define those properly if you're making a linux shared object without exporting all (potentially conflicting) internals.
|
||
|
|
This means you can compile it as a dll without any issues, one with a standardized interface. Any libqtv-specific bugfixes can be released independantly from engine(s).
|
||
|
|
Compiling a dll with msvc will generally automatically produce a .lib which you can directly link against. Alternatively, include both projects in your workspace and set up dependancies properly and it'll be automatically imported.
|
||
|
|
|
||
|
|
[PowerUser] issues:
|
||
|
|
its a full qtv proxy, but you can't get admin/rcon access to it.
|
||
|
|
it doesn't read any configs, and has no console, thus you cannot set an rcon password/port.
|
||
|
|
without console/rcon, you cannot enable any listening ports for other users.
|
||
|
|
if you need a public qtv proxy, use a standalone version.
