What changed in EDuke32, build by build

* make Ctrl-Alt-A (formerly 'toggle inner gray walls') now remove all gray walls entirely in 2d mode * make r_usenewaspect enabled by default

* fix breaking out of 'switch' blocks and compilation of the 'default' case * Have a way of assigning 'special function' menu [' F] entries to script states. Writing a string literal after the state name will register the state under that name. Menu names are limited to 24 characters and it's possible to have up to 16 of them. * new branching command 'ifinteractive', true if a state runs from the menu mentioned above. * new command: getnumberfromuser <<retvar>> "query_string" <maxnum> <flags> See 'state collect_teleporting_sectors' in a.m32 for a combined usage of the new functionality.

* helper feature: when shade preview is enabled, the ceilings and floors of highlighted sectors are shown in pal 6. This makes it possible to highlight the TROR-joining candidate sectors in 3D mode using e.g. 'sethighlightsector searchsector 1' while aiming at the respective ceilings and floors, and get visual feedback. * when failing TROR-joining early ('no consistent joining combinations found'), print to the console why it failed. * more Makefile.deps updating

* New shade/visibility calculation code, which is activated with 'r_usenewshading' (on by default), and is closer to the classic look. Also tweak the FOGSCALE macro to have approximately the same fog distance with all renderers. * Mapster32: END modifier to RShift. If it's pressed when RShift is released, sprites which are in grayed out sectors are also selected; Make changing shade affect all highlighted sprites in 3D mode (when aiming at one of them). * some debug code to watch out for suspicious glGenTexture/glDeleteTextures calls, not active.

First, it is now possible to disable the memcache (which is there to cache the texcache) by setting the new cvar 'r_memcache' to 0. Do this if you're constrained on memory or getting crashes when e.g. doing vidrestart often. Also, the memcache will disable itself (and free its storage, if it's there) the first time it fails to allocate. Fix a strcpy with identical arguments in game.c and a couple of uninitialized mem accesses related to Polymer lights.

Usage: For an ANM file <somefile>.anm/ANM, EDuke32 looks for <somefile>.ivf, which is the VP8 stream transported by an IVF container. It can be extracted from a WebM file with e.g. mkvextract tracks <filename>.webm 1:<filename>.ivf (part of Mkvtoolnix, the Matroska toolset) Libvpx is required, and the 'YUV'-->RGB conversion is implemented using a fragment shader, so it's for OpenGL modes only. Also, this commit doesn't enable the code. Unfinished: sound, aspect correction for fullscreen w/ non-square pixels, ... ? --- Make MAXNODESPERLINE in engine_priv.h actually a macro that depends on MAXYSAVES and MAXDIM instead of using the obsolete precomputed value. I think this might have been the cause for the latest patched-up overhead view crash.

* Read-only CON access to sector bunchnums by adding the labels '.ceilingbunch' and '.floorbunch' to the CON sector structure

* slightly tweaked status line, now also displaying the number of bunches * fix a couple of issues unearthed by valgrind and a TROR nextwall corruption when joining sectors

* it is now possible to paste (and have an outer red wall automatically) highlighted sectors into a sector that is extended on one side and non-sloped on the other. For this, the highlighted sectors must be in one connected component. * Make it possible to not display inner gray walls, toggled with Ctrl-Alt-A, but only when no manual grayout (Ctrl-R) is in effect. * bugfix: don't clear original TROR-nextwall link when duplicating extended highlighted sector * m32script: protect wall members relevant to TROR * save autogray (Ctrl-A) and showinnergray (see above) to mapster32.cfg

- sethighlightsector <sectnum> <on?> - updatehighlightsector - collectsectors <<array_to_collect_sectnums>> <initial_sector> <<num_collected_sectors>> <sector_filtering_state> The latter does a breadth-first search starting from an initial sector and collects nextsectors only when the filtering state, given a sectnum as RETURN input, writes a nonzero value into RETURN. As a usage example, a.m32 includes the state 'collect_teleporting_sectors', that collects all sectors containing an SE7 and highlights them afterwards. This way, it should be possible to retrofit old maps with TROR by distributing small scripts that do most of the work (right now, joining has to be done by hand, though). * corruption checker: for the 'nextwall inconsistent with nextsector' corruption, suggest an alternative fix by searching fitting nextwalls and changing the nextwall of the corrupt wall (as opposed to the nextsector). It will display with a leading '?' in the listing, and can be demanded by suffixing 'corruptcheck tryfix' with it. For example, corruptcheck tryfix 9-21 ? would fix some corruptions in Billy Boy's cranium.map without introducing drawing errors. * fix demo playback (tueidj figured this out)

* When dragging highlighted sprites, do a setsprite() after each position update. This way, they won't end up on the wrong level * TROR support for SE 31 and 32 in-game, example provided in test map * some uncommited stuff for TROR: SE 6/14

* Make the minimum resolution possible 640x480. Sometimes you'd accidentally enter something like 'vidmode 800 60' and crashes would ensue... * fix a warning

Implementation note: the so instrumented sprites use actor[].t_data[7] to hold a magic number (0x18190000 + pivot spr idx), and t_data[8] and [9] for the initial coords relative to the pivot point.
