What changed in EDuke32, build by build

The main feature is the addition of -mx and -mh command-line parameters to EDuke32 and Mapster32. These parameters include a con and def "module" respectively. This translates into essentially including the file from the bottom of the compiled script. I fixed the classic buggy behavior of the BROKEHYDROPLANT and REACTOR2 sprites. I also fixed a small, long-standing bug where FRAMEEFFECT1 blurs are not affected by sector floorpal. You can see one example of this by shrinking the Enforcer on the upper inside of the toppled building in E3L11: Freeway. I tweaked the Makefile so that it would automatically regenerate the keep.me files in the $(OBJ) and $(EOBJ) directories after they are deleted for cleaning. One final change is a slight positioning cleanup of both programs' --help dialog boxes.

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

- 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)

* 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.

"The most noticeable change is the addition of the "includedefault" CON and DEF command, which will attempt to include eduke.con (or nam.con, or ww2gi.con), then game.con, or duke3d.def, or nam.def, or ww2gi.def. This is useful for TCs like my add-ons, where for my pseudo-mutators I currently say "include EDUKE.CON", but I also have to juggle this terrible order of paths, so that I can have an EDUKE.CON file in my HRP which says "include GAME.CON" to allow the mainline game to actually run, but also allow DukePlus to load its EDUKE.CON file (since it uses that and not an -x switch), and also allow any custom EDUKE.CON files in the root to be used."

* Mapster32 now makes sandwiches, too: select all floors of a bunch and 'extend them below'. This will put a new sector between the highlighted ones and the their lower neighbors and displace the z's accordingly. Make sure you have enough headroom. * To facilitate the above, RAlt now has two more modifier keys (checked at release time, as usual): for every sector that would be selected, END will select all sectors whose floor bunchnum equals the first (this is useful for sandwiching), and HOME will select all sectors whose ceiling bunchnum equals it (not very useful, but provided for completeness). * Sloping extended sectors is now checked more rigorously -- misc: * When deleting highlighted sectors with DEL, pressing LShift will now always delete them irrespective whether the mouse pointer is over one of them. This is useful for the cleanup of corrupted maps. * 2D drawing is slightly tweaked so that active walls always display over inactive ones
