Added Z_EXT_PF_ONGROUND + Z_EXT_PF_SOLID for compat (not enabled serverside due to conflicts with pext - just a define away).
Fixed bug with loading screens switching sizes part way through loading.
Added hexen2 rain effect.
Fix hexen2 model texture alphas not working.
Fix potential linux crash from excessively long stdin lines.
Added cl_rollalpha cvar.
Fixed quirk where the player would slide along the base of steep walls/slopes.
Tweaked PM_NudgePosition to be more precise, giving more reliable prediction.
Fixed fread qc builtin.
Tweaked random() builtin to bias slightly away from 0, so that nextthink=random()*foo; will never cause statue-monsters.
Check for GL_WEBGL_depth_texture instead of just GL_OES_depth_texture, to fix compressedTex2d errors in firefox.
Second attempt at blocking invariant keyword with mesa.
Use xrandr for gamma where possible. This prevents reading stale XF86 gamma ramps and restoring those invalid ramps when quitting.
Try to grab mouse pointers slightly faster in x11.
Don't call XIFreeDeviceInfo if XIQueryDevice returned NULL.
Document parm_string and startspot qc globals.
Fix possible infinite loop from physics frames.
QTV: stripped most of the old plugin code (because really, who has a browser that still supports either ActiveX or NPAPI). Fixed up emscripten port references.
QTV: fix bug with protocol extensions not being reported to viewers.
QTV: use binary websockets instead of text.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5419 fc73d0e0-1445-4013-8a0c-d673dee63da5

git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5402 fc73d0e0-1445-4013-8a0c-d673dee63da5
Added scrollbars to various menus (when they're too tall for the virtual screen height).
Added warnings when qc draws to the screen outside of where it'll actually be displayed (freecs is guilty of this).
r_showshaders will now work in q2.
mod_texturelist will include a small preview, because I can.
plug_list command will now also display some plugins which are not currently loaded.
q1bsp now properly respects hitcontents (note that normally only hull 0 actually has contents other than solid+empty).
q1bsp now correctly reports content values in tracelines (this fixes freecs being unable to detect func_water).
Rewrote netgraph code. Now displays using polygons instead of textures for higher resolution graphs.
Fixed texture bug that appears with nouveau's core contexts (texture unit switches were not happening).
Added some better support for disabling vsync with nouveau, although its still broken fullscreen for some reason.
Changed fteqcc's warning for unrecognised CRCs. Should be more descriptive about the usual cause (but less technical and potentially technically wrong).
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5378 fc73d0e0-1445-4013-8a0c-d673dee63da5
Reworked glsl bones, so they work based upon the shader's version instead of the driver's version (more robust).
Fix te_teleport shader.
Track angles for antilag.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5372 fc73d0e0-1445-4013-8a0c-d673dee63da5

menuqc now makes sure that any fields it needs are actually present.
developer 1 should now report glsl line numbers a bit more reliably.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5284 fc73d0e0-1445-4013-8a0c-d673dee63da5
First real attempt at lit water.
Parsing rtlights is now aware of spotlights.
Default cl_yieldcpu to 1, to save cpu for anyone who sets cl_maxfps lower. Added to menus.
presets now include view angle clamping - maps made for quakespasm REQUIRE full pitch angles despite it otherwise being considered a cheat or glitchy (on servers that try to block the cheat).
fix r_fullbrightSkins>=1 issue.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5274 fc73d0e0-1445-4013-8a0c-d673dee63da5
Fix sound source issues in Q3.
Fix q2 air acceleration/prediction omission.
Don't change console completion while typing (while that option is still possible).
Shift+tab now cycles completion backwards (now ctrl+shift for cycle subconsoles).
Allow a few things to ignore sv_pure - including csprogs files (which is useful for all the mods that come with the csprogs.dat distributed separately).
clamp pitch values to the range documented by openal, to hopefully avoid error spam.
add some colour coding to the text editor when shader files are being edited/viewed.
Changed how overbrights are clamped on q3bsp.
Added portalfboscale for explicit texture scales on portal/refract/reflect fbos.
qc decompiler can now at least attempt to decompile qtest's qc.
fteqccgui can now be pointed at a .pak file, and decompile the progs.dat inside.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5269 fc73d0e0-1445-4013-8a0c-d673dee63da5
attempt to fix an issue with bc formats being rejected by d3d if they're not a multiple of 4.
added doreset argument to refreshhostcache builtin, for mods to forget all servers when rescanning.
stop fteqcc from reporting uninitialised locals etc inside the wrong file.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5251 fc73d0e0-1445-4013-8a0c-d673dee63da5
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.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5248 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
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
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

git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5194 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
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
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
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
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
addtrisoup_simple now supports line lists too.
fix a memory leak in the sound code.
fix chunked http download corruption in certain cases.
reworked the networking associated with entity editing. now carries ids instead of indexes (qc isn't aware of them).
'map blarg.map' will now auto-create a dummy map if it does not already exist. this should make it easier to get started with map editing.
fix some issues with banning yourself - loopback can now mute etc themselves, but not ban themselves.
downloads/updates menu now handles plugin detection. user-installed plugins will result in a prompt allowing the user to enable/disable/delete them. This makes using plugins more explicit.
revamped help menu to remove m_state
fix silly ode copypasta bug, added preliminary bullet code in case anyone is interested.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5090 fc73d0e0-1445-4013-8a0c-d673dee63da5
increase xz memory limit
fix fseek/fsize to match definitions.
r_deluxemapping is more aggressive with regards to generating lux files on demand (but won't generate lit data at the same time).
fix webgl shader issues.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5071 fc73d0e0-1445-4013-8a0c-d673dee63da5
tweak rtlights a bit, to not bug out on The Waste's decals.
use compatibility glsl in order to get ftransform working for consistent vertex coords (still uses core if there's no fixed function stuff). this fixes z-fighting issues with rtlights.
Rework punchangles for greater compatibility.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5059 fc73d0e0-1445-4013-8a0c-d673dee63da5
make the 'identify' command assume that a single decimal number is not an address (allowing it to be handled as a user id).
qcc: support default initialisers in function calls.
tweak filesystem code to try to flush individual files instead of discarding the entire fs hash.
fix 'snap' stuff.
other tweaks...
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5058 fc73d0e0-1445-4013-8a0c-d673dee63da5
implemented identify+iplog stuff for nq users.
r_tessellation forces blinn tessellation on meshes. can also be specified manually.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5055 fc73d0e0-1445-4013-8a0c-d673dee63da5
some tweaks to try to make webgl more robust.
added r_max_gpu_bones cvar. defaults to 0 in webgl for now (64 otherwise).
fixed gles2+skeletal issue that was breaking webgl (note r_max_gpu_bones needs to be set to 32 or something for it to actually use glsl bones with webgl).
sound rates now internally use decimals instead of percents. because meh.
allow PEXT2_MAXPLAYERS and angle deltas in nq.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5052 fc73d0e0-1445-4013-8a0c-d673dee63da5

integrate hlmdl a little better.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5031 fc73d0e0-1445-4013-8a0c-d673dee63da5
openal: doppler now applies to openal more consistently.
vulkan: vk_loadglsl cvar enables vk_nv_glsl_shader, with support for existing glsl shaders (still no permutations for now). needs !!samps stuff.
vulkan: r_renderscale now partly works. r_fxaa also works under specific circumstances. needs more work. still no bloom or projections stuff.
menu_download: got a few tweaks to improve it, including zips. I still want to handle engine updates with this stuff, but that can wait for later.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5008 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix some non-ascii encoding.
generate placeholder 8bit mipmaps for gles2/webgl in case anyone tries using 'vanilla' rendering.
revamping the downloads menu.
fix particles needing a specific blend mode in order to use custom shaders.
added trace_bone_id globals for qc. untested.
try to fix ragdoll crash. failing that, at least prevent it from being a crash.
try to fix d3d11 black lightmaps issue.
add r_norefresh to d3d9+d3d11
skin composing can now use subpics.
vulkan now tries to properly detect supported texture formats, instead of assuming.
vulkan now has a cvar to configure which dynamic buffers should be staged or shared.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5006 fc73d0e0-1445-4013-8a0c-d673dee63da5
fix some more compile-time issues.
fix some vulkan issues that are probably what's breaking amd gpus.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5005 fc73d0e0-1445-4013-8a0c-d673dee63da5
vulkan, wasapi, quake injector features added.
irc, avplug, cef plugins/drivers reworked/updated/added
openal reverb, doppler effects added.
'dir' console command now attempts to view clicked files.
lots of warning fixes, should now only be deprecation warnings for most targets (depending on compiler version anyway...).
SendEntity finally reworked to use flags properly.
effectinfo improved, other smc-targetted fixes.
mapcluster stuff now has support for linux.
.basebone+.baseframe now exist in ssqc.
qcc: -Fqccx supports qccx syntax, including qccx hacks. don't expect these to work in fteqw nor dp though.
qcc: rewrote function call handling to use refs rather than defs. this makes struct passing more efficient and makes the __out keyword usable with fields etc.
qccgui: can cope a little better with non-unicode files. can now represent most quake chars.
qcc: suppressed warnings from *extensions.qc
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5000 fc73d0e0-1445-4013-8a0c-d673dee63da5
isolated transfers a little.
added preliminary support for r1q2 and q2pro protocols (no zlib).
fixed some missing q2 hud configstrings.
fixed models attached to particles not appearing the first time around.
fixed halos appearing on {foo fullbright textures.
fix particle crash bug from missing particlecubes.
implement r_converteffectinfo (instead of r_importeffectinfo with r_exportalleffects) for convenience. also now more complete and more accurate.
loadfont no longer auto-allocates slot 0.
fix issues with r_dynamic -1
don't restart audio on vid_reload (only reload it). this fixes audio issues with capturedemo with gamedir changes.
fix possible crash from loading sounds during an audio reload/restart.
now listens on both ports 27500 and 26000 when running quake, by default. sv_port or -port args will override.
work around surfedge corruption in some instance of the slide4 map that dimman found.
attempt to nudge players to travel at at least 200qu when travelling vertically through portals. this should help alieviate gravity-induced stuttering issues.
fix nested function types used in conjunction with op_state. now assumes static within the parent.
optimise array indexes slightly.
fix issue with ptr[float].foo
fix some qcc bugs to do with implicit type conversions
fix a portal / angle protocol extension issue, so legacy clients can use portals, they just can't see the other side (nor predict them).
fix q2 victory.pcx issue at the end of the game.
use abort/sigabort instead of sigsegv on linux sys_errors. this should help get people to report stuff better.
reformat the nq server advertising to be more helpful.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4996 fc73d0e0-1445-4013-8a0c-d673dee63da5
added //it stuffcmd.
now parsing //wps stuffcmds for ezhud use.
rework worker threads a little so that the main thread is no longer guaranteed to be stalled at least once. This speeds up load times a little.
fix nq server player counts in the server browser.
fix switching from/to spectator mode from destroying frag counts.
tweak custom bf args a little.
fix issue with player names starting with char 0x80.
fix menu.dat not loading.
attempt to fix flush lag on windows.
some fixes for stencil shadows.
try to fix public builds not knowing their svn revision. this should fix autoupdates.
added global_gravitydir vector, for mods that want to be really weird. doesn't clear onground flags however.
reworked the status command a little to attempt to report bursts a little better.
fix multicasts missing in mvds issue.
fix illegible server message with dpp7 downloads.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4992 fc73d0e0-1445-4013-8a0c-d673dee63da5
tweaked cl_maxfps a little. now sticks much closer to the desired rate. also tweaked cl_netfps. clamps 77fps to 13ms frames (read: 76.9 fps) in an attempt to avoid tripping up any framerate checks (we had previously been using a lower net rate with occasional 14ms frames).
viewspace particles are now a thing.
greater control over spawning particles. its now possible to spawn particles only in slime, etc.
fix soundlength builtin.
preliminary version of r_dynamic -1, which can give some significant framerate boosts on certain maps.
fix halflife bsp texture issues.
rewrote worker thread logic. workers now work as a single pool, instead of independent pools. this means that you don't have to wait for a specific thread to finish before it can load new stuff, reducing overall load times some more. worker_count cvar allows reconfiguring the number of active workers. can be changed any time.
updated mod_terrain_create command. should be more useful now and make more sense when first loaded.
fix lit support. apparently its been broken for a while.
brush editor now has csg subtraction.
git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4990 fc73d0e0-1445-4013-8a0c-d673dee63da5
implement cfg_save_auto cvar, to replicated vanilla quake, ish. default off, obviously.
support for Q2RDF_IRGOGGLES (in combination with Q2RF_IR_VISIBLE). untested.
rework vectorvectors to be more predictable. v_right_z is now _much_ more commonly 0.
fix potential sound-related lock-up/console spam.
implement $colored_armor+$colored_powerup macros.
if command now copes with ' quotes.
fix crash on flushing q3bsps.
fix black bits with r_renderscale+cl_sbar 1
implement emulation for legacy q3 shaders when glsl is required. this is primarily for webgl right now, but potentially also useful with any gles2 port (fixme: still need to tweak d3d11 backend to support this too).
include scrollbar glyphs in the fallback font logic. this is primarily for download progress bars, especially with webgl.
don't try applying gamma to screenshots when using glsl.
