qc: qc temp-strings are now garbage collected. this makes strzone redundant. net: revert the player angles inversion thing from last build. hack some angles. gonna need to tweak the protocol. net: cl_lerp_players is smoother, and defaulted. lets see how many people complain. cl: fix juddering with chase_active+prediction. cl: download progress where the total size is not known now displays something more sane. cl: fixed some issues with rawinput keyboards. cl: added autoupdate option to the menu. cl: autoupdate defaults to a new 'tested' set of builds, instead of the completely untested svn builds. cl: added 'borderless windowed' option to the menus. works on windows. cl: saved games save a preview screenshot. cl: fix some memory leaks on shutdown. cl: added 'setrenderer random' option, might be useful for modders in that it helps highlight bugs/differences between renderers... qc: r_showbboxes now displays the fields of the various entities. tweaked entity lighting to overbright more gracefully. gl: fixed crepuscular lighting. qcc: added % operator. qcc: added inline keyword. qcc: some fixes for accessors. qccgui: now prompts for exe+basedir. sv: added sv_specprint, ala mvdsv. sv: stats now sent over the unreliable channel instead of the reliable one. this allows them to change more frequently. sv: rewrote speedcheat detection. clients will be throttled instead of kicked. unresponsive clients will be simulated instead of freezing in mid-air. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4829 fc73d0e0-1445-4013-8a0c-d673dee63da5

Also simplified modifier keys - they no longer trigger random events when pressing the modifier key itself. Right modifiers can now be bound separately from left modifiers. Right will use left's binding if not otherwise bound. Bind assumes left if there's no prefix. multiplayer->setup->network menu no longer crashes. added rgb colours to the translation view (but not to the colour-changing keys). added modelviewer command to view models. added menu_mods menu to switch mods in a more friendly way. will be shown by default if multiple manifests exist in the binarydir. clamped classic tracer density. scrag particles no longer look quite so buggy. added ifdefs to facilitate a potential winrt port. the engine should now have no extra dependencies, but still needs system code+audio drivers to be written. if it can't set a renderer, it'll now try to use *every* renderer until it finds one that works. added experimental mapcluster server mode (that console command). New maps will be started up as required. rewrote skeletal blending code a bit. added cylinder geomtypes. fix cfg_save writing to the wrong path bug. VFS_CLOSE now returns a boolean. false means there was some sort of fatal error (either crc when reading was bad, or the write got corrupted or something). Typically ignorable, depends how robust you want to be. win32 tls code now supports running as a server. added connect tls://address support, as well as equivalent sv_addport support. exposed basic model loading api to plugins. d3d11 backend now optionally supports tessellation hlsl. no suitable hlsl provided by default. !!tess to enable. attempted to add gamma ramp support for d3d11. added support for shader blobs to speed up load times. r_shaderblobs 1 to enable. almost vital for d3d11. added vid_srgb cvar. shadowless lights are no longer disabled if shadows are not supported. attempt to add support for touchscreens in win7/8. Wrote gimmicky lua support, using lua instead of ssqc. define VM_LUA to enable. updated saved game code. can again load saved games from vanilla-like engines. changed scale clamping. 0.0001 should no longer appear as 1. changed default mintic from 0.03 to 0.013 to match vanilla qw.

rewrote ban code, merging bans+nonbans+cuffs+mute+cripple+deaf+lagged+vip. added timeouts. new penalties have no dedicated command. use the addip command for it. maplist command now generates links. implemented skin objects for q3. added a csqc builtin for it. also supports compositing skins. playing demos inside zips/pk3s/paks should now work. bumped default rate cvar. added cl_transfer to attempt to connect to a new server without disconnecting first. rewrote fog command. alpha and mindist arguments are now supported. fog change also happens over a short time period. added new args to the showpic console command. can now create clickable items for touchscreen/absmouse users. fixed menus to properly support right-aligned text. this finally fixes variable-width fonts. rewrote console tab completion suggestions display. now clickable links. strings obtained from qc are now marked as const. this has required quite a few added consts all over the place. probably crappy attempt at adding joypad support to the sdl port. no idea if it works. changed key bind event code. buttons now track which event they should trigger when released, instead of being the same one the whole time. this allows +forward etc clickable buttons on screen. Also simplified modifier keys - they no longer trigger random events when pressing the modifier key itself. Right modifiers can now be bound separately from left modifiers. Right will use left's binding if not otherwise bound. Bind assumes left if there's no prefix. multiplayer->setup->network menu no longer crashes. added rgb colours to the translation view (but not to the colour-changing keys). added modelviewer command to view models. added menu_mods menu to switch mods in a more friendly way. will be shown by default if multiple manifests exist in the binarydir. clamped classic tracer density. scrag particles no longer look quite so buggy. added ifdefs to facilitate a potential winrt port. the engine should now have no extra dependencies, but still needs system code+audio drivers to be written. if it can't set a renderer, it'll now try to use *every* renderer until it finds one that works. added experimental mapcluster server mode (that console command). New maps will be started up as required. rewrote skeletal blending code a bit. added cylinder geomtypes. fix cfg_save writing to the wrong path bug. VFS_CLOSE now returns a boolean. false means there was some sort of fatal error (either crc when reading was bad, or the write got corrupted or something). Typically ignorable, depends how robust you want to be. win32 tls code now supports running as a server. added connect tls://address support, as well as equivalent sv_addport support. exposed basic model loading api to plugins. d3d11 backend now optionally supports tessellation hlsl. no suitable hlsl provided by default. !!tess to enable. attempted to add gamma ramp support for d3d11. added support for shader blobs to speed up load times. r_shaderblobs 1 to enable. almost vital for d3d11. added vid_srgb cvar. shadowless lights are no longer disabled if shadows are not supported. attempt to add support for touchscreens in win7/8. Wrote gimmicky lua support, using lua instead of ssqc. define VM_LUA to enable. updated saved game code. can again load saved games from vanilla-like engines. changed scale clamping. 0.0001 should no longer appear as 1. changed default mintic from 0.03 to 0.013 to match vanilla qw. I don't know why it was at 0.03. probably a typo. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4623 fc73d0e0-1445-4013-8a0c-d673dee63da5

PEXT2_REPLACEMENTDELTAS tweaked, now has 4 million entity limit. still not enabled by default. TE_BEAM now maps to a separate TEQW_BEAM to avoid conflicts with QW. added android multitouch emulation for windows/rawinput (in_simulatemultitouch). split topcolor/bottomcolor from scoreboard, for dp's colormap|1024 feature. now using utf-8 for windows consoles. qcc warnings/errors now give clickable console links for quick+easy editing. disabled menutint when the currently active item changes contrast or gamma (for OneManClan). Added support for drawfont/drawfontscale. tweaked the qcvm a little to reduce the number of pointers. .doll file loading. still experimental and will likely crash. requires csqc active, even if its a dummy progs. this will be fixed in time. Still other things that need cleaning up. windows: gl_font "?" shows the standard windows font-selection dialog, and can be used to select windows fonts. not all work. and you probably don't want to use windings. fixed splitscreen support when playing mvds. added mini-scoreboards to splitscreen. editor/debugger now shows asm if there's no linenumber info. also, pressing f1 for help shows the shortcuts. Added support for .framegroups files for psk(psa) and iqm formats. True support for ezquake's colour codes. Mutually exclusive with background colours. path command output slightly more readable. added support for digest_hex (MD4, SHA1, CRC16). skingroups now colourmap correctly. Fix terrain colour hints, and litdata from the wrong bsp. fix ftp dual-homed issue. support epsv command, and enable ipv6 (eprt still not supported). remove d3d11 compilation from the makefile. the required headers are not provided by mingw, and are not available to the build bot, so don't bother. fix v *= v.x and similar opcodes. fteqcc: fixed support for áéíóú type chars in names. utf-8 files now properly supported (even with the utf-8 bom/identifier). utf-16 also supported. fteqcc: fixed '#if 1 == 3 && 4' parsing. fteqcc: -Werror acts on the warning, rather than as a separate error. Line numbers are thus more readable. fteqcc: copyright message now includes compile date instead. fteqccgui: the treeview control is now coloured depending on whether there were warnings/errors in the last compile. fteqccgui: the output window is now focused and scrolls down as compilation progresses. pr_dumpplatform command dumps out some pragmas to convert more serious warnings to errors. This is to avoid the infamous 'fteqcc sucks cos my code sucks' issue. rewrote prespawn/modelist/soundlist code. server tracks progress now. ------------------------------------------------------------------------ git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4167 fc73d0e0-1445-4013-8a0c-d673dee63da5

rewrote ban code, merging bans+nonbans+cuffs+mute+cripple+deaf+lagged+vip. added timeouts. new penalties have no dedicated command. use the addip command for it. maplist command now generates links. implemented skin objects for q3. added a csqc builtin for it. also supports compositing skins. playing demos inside zips/pk3s/paks should now work. bumped default rate cvar. added cl_transfer to attempt to connect to a new server without disconnecting first. rewrote fog command. alpha and mindist arguments are now supported. fog change also happens over a short time period. added new args to the showpic console command. can now create clickable items for touchscreen/absmouse users. fixed menus to properly support right-aligned text. this finally fixes variable-width fonts. rewrote console tab completion suggestions display. now clickable links. strings obtained from qc are now marked as const. this has required quite a few added consts all over the place. probably crappy attempt at adding joypad support to the sdl port. no idea if it works. changed key bind event code. buttons now track which event they should trigger when released, instead of being the same one the whole time. this allows +forward etc clickable buttons on screen. Also simplified modifier keys - they no longer trigger random events when pressing the modifier key itself. Right modifiers can now be bound separately from left modifiers. Right will use left's binding if not otherwise bound. Bind assumes left if there's no prefix. multiplayer->setup->network menu no longer crashes. added rgb colours to the translation view (but not to the colour-changing keys). added modelviewer command to view models. added menu_mods menu to switch mods in a more friendly way. will be shown by default if multiple manifests exist in the binarydir. clamped classic tracer density. scrag particles no longer look quite so buggy. added ifdefs to facilitate a potential winrt port. the engine should now have no extra dependencies, but still needs system code+audio drivers to be written. if it can't set a renderer, it'll now try to use *every* renderer until it finds one that works. added experimental mapcluster server mode (that console command). New maps will be started up as required. rewrote skeletal blending code a bit. added cylinder geomtypes. fix cfg_save writing to the wrong path bug. VFS_CLOSE now returns a boolean. false means there was some sort of fatal error (either crc when reading was bad, or the write got corrupted or something). Typically ignorable, depends how robust you want to be. win32 tls code now supports running as a server. added connect tls://address support, as well as equivalent sv_addport support. exposed basic model loading api to plugins. d3d11 backend now optionally supports tessellation hlsl. no suitable hlsl provided by default. !!tess to enable. attempted to add gamma ramp support for d3d11. added support for shader blobs to speed up load times. r_shaderblobs 1 to enable. almost vital for d3d11. added vid_srgb cvar. shadowless lights are no longer disabled if shadows are not supported. attempt to add support for touchscreens in win7/8. Wrote gimmicky lua support, using lua instead of ssqc. define VM_LUA to enable. updated saved game code. can again load saved games from vanilla-like engines. changed scale clamping. 0.0001 should no longer appear as 1. changed default mintic from 0.03 to 0.013 to match vanilla qw. I don't know why it was at 0.03. probably a typo. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4623 fc73d0e0-1445-4013-8a0c-d673dee63da5

Also simplified modifier keys - they no longer trigger random events when pressing the modifier key itself. Right modifiers can now be bound separately from left modifiers. Right will use left's binding if not otherwise bound. Bind assumes left if there's no prefix. multiplayer->setup->network menu no longer crashes. added rgb colours to the translation view (but not to the colour-changing keys). added modelviewer command to view models. added menu_mods menu to switch mods in a more friendly way. will be shown by default if multiple manifests exist in the binarydir. clamped classic tracer density. scrag particles no longer look quite so buggy. added ifdefs to facilitate a potential winrt port. the engine should now have no extra dependencies, but still needs system code+audio drivers to be written. if it can't set a renderer, it'll now try to use *every* renderer until it finds one that works. added experimental mapcluster server mode (that console command). New maps will be started up as required. rewrote skeletal blending code a bit. added cylinder geomtypes. fix cfg_save writing to the wrong path bug. VFS_CLOSE now returns a boolean. false means there was some sort of fatal error (either crc when reading was bad, or the write got corrupted or something). Typically ignorable, depends how robust you want to be. win32 tls code now supports running as a server. added connect tls://address support, as well as equivalent sv_addport support. exposed basic model loading api to plugins. d3d11 backend now optionally supports tessellation hlsl. no suitable hlsl provided by default. !!tess to enable. attempted to add gamma ramp support for d3d11. added support for shader blobs to speed up load times. r_shaderblobs 1 to enable. almost vital for d3d11. added vid_srgb cvar. shadowless lights are no longer disabled if shadows are not supported. attempt to add support for touchscreens in win7/8. Wrote gimmicky lua support, using lua instead of ssqc. define VM_LUA to enable. updated saved game code. can again load saved games from vanilla-like engines. changed scale clamping. 0.0001 should no longer appear as 1. changed default mintic from 0.03 to 0.013 to match vanilla qw.

fix colormod added frag message filter, and dedicated frag tracker. added 'windowed consoles' for social-type stuff without depending upon csqc mods for it. added in_deviceids command which allows listing/renumbering device ids. slider widgets now support inverted ranges, so gamma selection isn't so weird. fix top/bottom colour selection bug. software banding feature is now part of the 'software' preset (now that it supports mipmaps). support for loading .maps, and editing their brushes etc (with appropriate qc mod). 'map mymap.map' to use. expect problems with missing wads and replacement textures overriding them and messing up texture scales. snd_inactive is now default. fix threading issue with wavs, no more error from 0-sample-but-otherwise-valid wavs. added -makeinstaller option to embed a manifest inside the exe (and icon). the resulting program will insist on installing the game if its run from outside a valid basedir. framegroup support for q1mdl. textures are now loaded on multiple worker threads, for reduced load times. moo har har. netgraph shows packet+byte rates too. added r_lightstylescale, pretty similar to contrast, but doesn't impose any framerate cost, but may have overbrighting issues. r_softwarebanding now works on q2bsp too. fixed crepuscular lights. gzip transfer encoding is performed while downloading, instead of inducing stalls. FINALLY fix ezquake download compat issue (dimman found the issue). git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4851 fc73d0e0-1445-4013-8a0c-d673dee63da5
