keys: add some extra key names for compat with DP+QS (primarily gamepad buttons).
keys: fix a few keys getting mistranslated between engine and qc scancodes.
engine menus: remove 16bpp from the video options menu on win8+, as win8 no longer supports anything but rgbx8.
pmove: coord size and rounding is now part of the pmove code itself. this fixes truncation issues.
r_clutter_density: fix crash from clutter comprising of boneless iqms.
gl: added cvars to disable immutable buffers or textures. hopefully these might be usable to work around the issue reported on various geforce 1080s
wav: convert ieee wav files to 16bit on load, in case someone tries giving us one of these.
vid_srgb: this cvar now uses -1 for the former gamma-only setting.
r_viewmodel_quake: new cvar (name comes from quakespasm) that can be used to disable the weird movement of the viewmodel when pitching up or down.
nquake: try to block nquake's frogbot's autoexec.cfg, as I keep getting complaints about it fucking over singleplayer games.
fs: added -netquake commandline argument that disables the use of the qw/ gamedir.
fog: disabled fog on aky surfaces, as it was bugging out in The Wastes.
vid: fix some vid_restart/vid_reload issues (which got much worse recently in my attempt to fix a different crash)
routing: first attempt at engine-side routing. feature is currently disabled.

r_showshaders 1 now shows the filename.
block 16bit rendering on win8+.
be more aggressive at starting a video mode when the system refuses to set a video mode.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5246 fc73d0e0-1445-4013-8a0c-d673dee63da5
add modifier key combos to bind arg completion.
don't force completion quite so aggressively.
completion is now more consistent with cl_chatmode 0.
alt key allows moving the cursor into console links to edit them (instead of treating them as immutable blobs on the input line).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5245 fc73d0e0-1445-4013-8a0c-d673dee63da5
rewrote tab completion logic. should no longer consume so much cpu time.
added tab-completion for the connect command. server lists must have been requested previously (like the connectbr command requires).
fix q1bsp fencetexture+fog combo.
fix wateralpha/lavaalpha/slimealpha/telealpha worldspawn fields.
added a couple of extra cvars to some rulesets.
fix d3d9 mipmap-size issue.
fix vid_reload issue (was crashing, but its also possible that it could have been the cause of VBO corruption).
made pausable default to empty, allowing for smarter defaults like pausing SP but not DM.
attempt to compensate for NQ's framerate-dependant waterjumps by making QW waterjumps slightly more permissive.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5241 fc73d0e0-1445-4013-8a0c-d673dee63da5
moved various config saving options to features, buttons saving is now disabled by default.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5239 fc73d0e0-1445-4013-8a0c-d673dee63da5
add stof to the lua logic.
fix an issue where q3bsp cvars were not registered in The Wastes build config leaving it subject to the worst of q3map2's lightmap allocation logic.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5236 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix possible out-of-range issue with qc ent references.
shader parsing is now a little more strict.
lua code support updated to bring it more in line with hifi's efforts, still not enabled by default.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5233 fc73d0e0-1445-4013-8a0c-d673dee63da5
also, 'cmd setinfo' without extra args was spamming the server's console instead of the client's.

splitscreen can now properly be configured via build configs, and potentially more than just 4 seats.
fix splitscreen and enemycolour forcing. forcing now works, but only when all seats are on/spectating the same team.
fix demo playback issue with http urls with webgl that don't allow streaming.
srgb fixes for the scoreboard.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5229 fc73d0e0-1445-4013-8a0c-d673dee63da5
Attempted to clean up build configs slightly, now ALWAYS using a build config.
Now enabling wayland renderer by default on linux (activates by default only when x11 fails).
Given linux servers the ability to chroot (will be used by default if run as suid-root).
Fixed a couple of vulkan warnings.
Makefile now treats speex like any other library.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5227 fc73d0e0-1445-4013-8a0c-d673dee63da5
Fixed weirdness around a second DP client bug (less serious) where a reconnecting DP client sends a disconnect request as soon as it gets its new connection. The client will still get disconnected (as per its apparent request), but FTE will no longer alarm admins, and the user should see something like 'unconnected dropped'.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5219 fc73d0e0-1445-4013-8a0c-d673dee63da5
reduced input latency.
reworked how internal texture formats work,.
added support for LIGHTING_E5BGR9 bspx lump for HDR lighting.
updated support for srgb, no longer looks quite so weird. works on glx
vid_srgb 3 attempts to use half-float swapchains, where possible.
gl: use glTextureStorage where available.
d3d11: gave up on using dxgi for fullscreen, was just too buggy.
glx: updated gl context creation on linux.
server: fix svc_updatefrags not being passed though (fixes frikbot scores)
fs: spanned pk3s now work (fragmented files/directory will fail to open, so this needs a custom tool to be fully useful).
fixed restart_ents command (restarts the map, but preserving the players as they are)
tw: removed 'QWSKINS' featureset from tw config
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5217 fc73d0e0-1445-4013-8a0c-d673dee63da5
don't archive csprogs when it's getting saved into demos anyway.
bound bones when using a model with less bones than the relative skeletal object.
mute(dprint) xinput restarts.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5205 fc73d0e0-1445-4013-8a0c-d673dee63da5
attempt to implement 'simple csqc' api.
handle qw+nq gunshot+blood+lightning differently - they do actually have different particle spawn patterns (qw is a single point, so spreads wider).
fix q3ui logo mesh thing. work around q3ui player meshes on d3d.
split video and renderer latching, so vid_reload delatches more stuff.
fix autosprite+autosprite2 in 6 different renderers...
added fog volumes to d3d9 renderer.
using matrix hacks instead of glDepthRange, this should give more consistent behaviour, especially now that we have r_viewmodel_fov.
small cleanup for gl shadowmaps to make the interface more consistent with other renderers.
added patchDef2 parsing to fte's .map loader, doesn't actually use it though.
some fixes for q3's shaders, including to try to get overbright working better.
updated customskin api to give more control.
first attempt at a packager system for fteqccgui. probably useless, but whatever.
menusys changes to try to support QSS's csqc.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5200 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix sv_nqplayerphysics+spectators = spectators able to shoot
fix watervis bug, turned out to potentially be more serious.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5194 fc73d0e0-1445-4013-8a0c-d673dee63da5
try to get game controller defaults a little closer to QS.
mess with r_dynamic 2 a little, to more closely match vanilla.
fix under-lighting bug on models. added extra model lighting pathway for greater vanilla compat, as part of software-banding.
fix proquake-client compat issue.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5192 fc73d0e0-1445-4013-8a0c-d673dee63da5
xonotic: fix jumppads not working while onground.
attempt to parse meag's protocol changes, in case we get a .qwd from ezquake. does not report them to servers at this time.
added cl_fullpitch cvar. only affects nq servers that lack serverinfo.
support dds/ktx-based cubemaps, including for skyboxes.
recognise multiple new compressed texture formats - bc1-7, etc1+2+eac,.astc. Addeded to supporting drivers/apis.
software decoder for etc2,bc4+bc5 textures, so they can be considered universal (but with fallbacks).
software decoder for bc1-bc3 textures, but disabled due to lingering patent paranoia.
report heartbeats once, by default.
r_viewmodel_fov support for vk+d3d9+d3d11 renderers.
fix depth projection differences with various renderers (min dist is now consistent).
added some code to announce when cl_delay_packets changes.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5188 fc73d0e0-1445-4013-8a0c-d673dee63da5
try to fix the recent network issues, the slightly more sane way.
added a r_viewmodel_fov cvar, to optionally control the viewmodel's fov separately from view fov.
updatesound now auto-starts the sound if it wasn't already playing, but only if a sound name was specified.
small optimisation for xonotic. Delay the actual fopen until the first read. This avoids the worst of the hitches every time a footstep sound is played (no more zlib decompression).
r_lightprepass now respects rtlight modes.
optimised some rtlight pvs bits. should hopefully be slightly more efficient.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5186 fc73d0e0-1445-4013-8a0c-d673dee63da5
added cl_iDrive cvar.
tried to solve invalid server address errors.
fixed envmap+screenshot_cubemap commands (they write slightly different cubemaps).
rework server favourites a little, to avoid conflicts with other engines.
fix legacy rtlights on certain maps.
added 'rgbgen entitylighting' for lighting with colormod support.
decompiler should cope with more instructions now. pretty much just switch opcodes that are bugged now.
implemented a couple of joint types into the bullet plugin. still useless though.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5180 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix decals again. clampmap should work properly with them, also removed the extra part.
fix rtlight pvs issue with respect to portals
fix vid_reload causing the d3d9 renderer to use nearest sampling
terrain system should now mostly work with d3d9. still has issues.
fix q3 volumetric fog not applying to models
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5174 fc73d0e0-1445-4013-8a0c-d673dee63da5
opus should now be statically linked or something
made the denormalised floats warning look less scary.
fix the console-making-hud-pics invisible issue
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5172 fc73d0e0-1445-4013-8a0c-d673dee63da5
minor tweak to prediction logic. bob logic will no longer stutter in eg freecs.
reworked config ordering. autoexec-after-fte.cfg will now be enforced.
reworked rawinput logic to avoid mouse button states getting stale due to separate mouse drivers when enabling the cursor.
fixed invalid commands getting silently ignored when not connected to a server.
allow execution of menu.dat from packages specified by the fmf.
FS_NativePath now responds properly to FS_GAME, and will return logical paths, instead of mimicing FS_GAMEONLY.
d3d9: fix tcgen skybox
qcc: fix crash with __out keyword.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5171 fc73d0e0-1445-4013-8a0c-d673dee63da5
unicast svc_cgamepackets will now report which seat they were unicast to.
sendevent will now reveal the seat that was active at the time of the call.
csqc console commands will now reveal any p2 etc commands that were used.
added 144hz refresh rate option to the built-in menu
added sv_demo_write_csqc cvar to write csprogs.dat into mvds. I still need to read them...
make irc client not create new accounts if there's already a connection registered for the given server.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5169 fc73d0e0-1445-4013-8a0c-d673dee63da5
try to do something about crazy cursor biases in games that are not likely to get the QSG cursor.
fix unvised q3bsp pvs. again.
add cl_delay_packets cvar as a clientside analogue to sv_minping (which is often unchangeable by the actual players).
fix a qcc issue with static locals screwing everything up.
fix dpmaster issues when NQPROT isn't defined.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5168 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix capturedemo over vid reloads.
fix playfilm letterboxing issue.
con_printf will now create consoles as needed.
fix .skin compose line.
fix a couple of q3bsp issues
core gl contexts will no longer be given pre-core glsl shaders, is the theory.
qcc now warns about unused fields. use the __used keyword to mark those fields as actually needed. use __unused to allow the qcc to potentially silently strip them.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5166 fc73d0e0-1445-4013-8a0c-d673dee63da5
this should fix the case issues on freecs's wads. note that the basedir and gamedirs are still not case insensitive, and it requires fs_cache enabled (which may still get temp-disabled following file writes, which I still need to fix, so downloads might still break things but fs_restart;vid_reload should fix them in that case).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5164 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix logicops following vector types to shortcircuit properly.
fix ternary operators ending in field references - no longer ignores the result of the true pathway.
these two fixes appear to be sufficient to compile xonotic (note the array bounds issues that are abundant in xonotic, which will break with -TFTE and its direct array indexing, so be sure to re-enable bounds checks). The result probably isn't perfect, but it seems to work for me.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5162 fc73d0e0-1445-4013-8a0c-d673dee63da5
Try to optimise a few maths builtins when given constant args, in an attempt to make up for the perf lost...
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5159 fc73d0e0-1445-4013-8a0c-d673dee63da5
reworked deferred rendering to support specular. mrt can be reconfigured by TCs if desired.
reworked q3bsp deluxemap code (so it no longer bugs out).
fixed a few warnings.
updated fteqcc to try to cope with xonotic. still not working (xonotic fails from bound checks).
reworked shader conditionals to support elif. added some directives from QF(aka: warsow)
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5158 fc73d0e0-1445-4013-8a0c-d673dee63da5
added .ktx image support as an alternative to .dds, primarily for etc2 compression (which should work on all gles3 devices, or gl4.3), only known representations will work.
rework z-fighting workaround. now only enabled on known vanilla maps.
added splitscreen option to the singleplayer menu.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5154 fc73d0e0-1445-4013-8a0c-d673dee63da5
some more tweaks for xonotic
rcon-over-xmpp, because I can. Server might see your rcon password, so watch out for that.
qcc tweaks.
updated q1qvm api stuff to api version 15.
android port updated. egl now handled by native code, which means we now have proper control over everything and can default to gles2. requires android 2.0+. vulkan-on-android renderer added, but not tested.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5153 fc73d0e0-1445-4013-8a0c-d673dee63da5
log_dir prefixed with ./ will work as relative to quake's basedir (files will get .log postfix).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5149 fc73d0e0-1445-4013-8a0c-d673dee63da5
Added sv_guidkey cvar, allowing cross-server guid key generation (although it lacks auth).
Support .ico, because we can.
preliminary support for sdl 2.0.6's vulkan stuff. will wait till its actually released before its properly used.
Fix capturedemo.
videomap should typically use premultiplied alpha, apparently.
Updated sound drivers. No more old drivers. Better cvar registration. More drivers optionally support float output.
Added certificate log for dtls connections.
Rewrote font char cache, now supports full unicode char range, not just ucs-2. Attempt to support FreeType 2.5+ rgba fonts.
XMPP now supports carbons, and shows avatars in conversations. Updated xmpp's scram auth to be more strict, including the plus variation (hopefully), to block evil tls proxies.
ffmpeg plugin now uses the decoupled api for decoding too.
Cef plugin updated to support fte-scheme post data properly, as well as request/response headers (like cross-origin).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5148 fc73d0e0-1445-4013-8a0c-d673dee63da5
Add separate cl_movement cvar to enable/disable reporting input sequences to DP servers (which use different pathways). Does not affect other protocols. This is separate from cl_nopred but will usually have the same result in the long run.
Fixed movevalues for DPP7 clients, if they try using prediction they should now (mostly) get the same values that DP normally uses for QW servers.
Reworked sky overrides somewhat. Now uses skyboxes where possible.
Fixed dpcompat_makeshitup a little, for better compat.
Fixed echo $foo$bar not exanding bar.
Try to fix the meanings of vid_hardwaregamma.
Fixes for builtins/features/etc that apparently only xonotic uses.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5143 fc73d0e0-1445-4013-8a0c-d673dee63da5
android gets a couple more gamepad buttons.
gamepads now have separate keybindings. I've created some default binds for mods that are unaware of gamepad buttons.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5142 fc73d0e0-1445-4013-8a0c-d673dee63da5
PF_VarString can now shortcircuit, directly returning the first argument (which also bypasses related length limitations). this required const correctness fixes.
r_showshaders cvar reports the wall texture being pointed at.
improve dp compat in a number of areas, should now mostly be able to run xonotic 0.8.2, but will need some more extra cvars/defaults/stuff.
fix q3bsp loader race condition.
fix dpm loader multi-surface issue.
remove limit on stringbuffer count.
don't poll xinput (because its disturbingly slow), instead wait for some window message before re-checking.
fixed splitscreen saved games.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5140 fc73d0e0-1445-4013-8a0c-d673dee63da5
q2 temp entity tweaks. still more work to be done.
support sRGB (mostly)properly in gl+vk+d3d9+d3d11.
vulkan tweaks - multisample works under certain conditions. additional other changes to comply... cvars to enable some other device extensions.
removed r_viewleaf. now using clusters for q1 too.
improved compat with quakespasm's sky command.
Added vid_winthread cvar, to handle window messages on a separate thread. When set this allows the game to keep redrawing when the user is resizing the window etc.
Finally added renderers option to menusys.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5130 fc73d0e0-1445-4013-8a0c-d673dee63da5
demo menu now properly lists the contents of archives.
demos played from subdirs/archives can now chain properly.
autodetect nehahra's demos. Add -nehahra argument to register/override cvar defaults (and set the right gamedir+startmap).
fix some q2 download bugs.
lame attempt at proper sRGB support (gl+vk+d3d9+d3d11 renderers).
fix q3bsp wrong-lightmaps bug.
match DP's viewzoom behaviour by not applying it when VF_[A]FOV was explicitly used.
fix d3d9 issue with missing textures screwing up blend modes.
vk: use a staging buffer instead of a staging textures per mip.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5128 fc73d0e0-1445-4013-8a0c-d673dee63da5

misc other irrelevant tweaks.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5120 fc73d0e0-1445-4013-8a0c-d673dee63da5
remove MAX_MAP_LEAFS limit, although its still checked for sanity (just MUCH higher). You may need 64bit processes on account of the pvs+phs memory required.
integrated my fork of frikdec into fteqccgui. Just associate .dat with fteqccgui and it'll decompile the progs (compiling will then embed the decompiled source into the resulting .dat to avoid repeated decompilation). Be sure to back up first... not tested as a 64bit process.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5114 fc73d0e0-1445-4013-8a0c-d673dee63da5
splitscreen: split spectator setting into a per-seat setting. scoreboards are now also per-seat.
added parm_string global for richer map change stuff.
dpp7: fixed and reinstated.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5110 fc73d0e0-1445-4013-8a0c-d673dee63da5
implement redirectcmd. because I can.
add a few more qc extensions that define features already implemented.
changing/restarting the map will explicitly flush the worldmodel if the file's modification time is newer. this should make map editing a little nicer.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5106 fc73d0e0-1445-4013-8a0c-d673dee63da5
try to work around a Chrome webaudio bug, to stop an exception preventing the webgl port from starting any maps.
don't open so many ipv6 client sockets (hybrid sockets don't need it).
fix fteqcc to support qccx a bit better. crmod should now compile when using -fqccx, seems to work in proquake too (ignoring the string replacer hack/tool).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5105 fc73d0e0-1445-4013-8a0c-d673dee63da5
mouse+kb+soundblaster devices should work.
you can compile a dedicated server, but the lack of any networking support makes it a bit pointless.
the software renderer will work, but its crap and gets absolutely dire framerates.
there's no code to init mesa or anything, so its crappy-software rendering only.
I doubt anything useful will ever result from this, but it was still interesting to do. possibly the only useful thing to come from this will be from limiting ram use.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5104 fc73d0e0-1445-4013-8a0c-d673dee63da5
schannel (ie: windows native) works as a client, not a server.
gnutls provides both client+server support. servers need to load a pre-generated cert from disk.
tweaked gamepads to actually work in the web target.
tweak gamepads a bit. added gp_* bind aliases. xinput+sdl+web should all use the same key mappings.
finally added the itemtimer glsl.
tweaked software renderer to not be quite so buggy, but you probably won't realise that if you try it.
disabled the ill-fated QWOVERQ3 feature.
don't do the oldorigin thing in quakeworld mods. hopefully this'll fix cspree's weird stuck-in-floor issue.
dpp7 is buggy serverside. disabled for now. I'm part way through rewriting its deltas.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5103 fc73d0e0-1445-4013-8a0c-d673dee63da5
reworked network addresses to separate address family and connection type. this should make banning people more reliable, as well as simplifying a whole load of logic (no need to check for ipv4 AND ipv6).
tcpconnect will keep trying to connect even if the connection wasn't instant, instead of giving up instantly.
rewrote tcp connections quite a bit. sv_port_tcp now handles qtv+qizmo+http+ws+rtcbroker+tls equivalents.
qtv_streamport is now a legacy cvar and now acts equivalently to sv_port_tcp (but still separate).
rewrote screenshot and video capture code to use strides. this solves image-is-upside down issues with vulkan.
ignore alt key in browser port. oh no! no more red text! oh no! no more alt-being-wrongly-down-and-being-unable-to-type-anything-without-forcing-alt-released!
reworked audio decoder interface. now has clearly defined success/unavailable/end-of-file results. this should solve a whole load of issues with audio streaming.
fixed various openal audio streaming issues too. openal also got some workarounds for emscripten's poor emulation.
fixed ogg decoder to retain sync properly if seeked.
updated menu_media a bit. now reads vorbis comments/id3v1 tags to get proper track names. also saves the playlist so you don't have to manually repopulate the list so it might actually be usable now (after how many years?)
r_stains now defaults to 0, and is no longer enabled by presets. use decals if you want that sort of thing.
added fs_noreexec cvar, so configs will not be reexeced on gamedir change. this also means defaults won't be reapplied, etc.
added 'nvvk' renderer on windows, using nvidia's vulkan-inside-opengl gl extension. mostly just to see how much slower it is.
fixed up the ftp server quite a lot. more complete, more compliant, and should do ipv6 properly to-boot. file transfers also threaded.
fixed potential crash inside runclientphys.
experimental sv_antilag=3 setting. totally untested. the aim is to avoid missing due to lagged knockbacks. may be expensive for the server.
browser port's websockets support fixed. experimental support for webrtc ('works for me', requires a broker server).
updated avplug(renamed to ffmpeg so people know what it is) to use ffmpeg 3.2.4 properly, with its new encoder api. should be much more robust... also added experimental audio decoder for game music etc (currently doesn't resample, so playback rates are screwed, disabled by cvar).
