846214a164 Move insertsprite() and deletesprite() into engine.c instead of being inlined.
These operations aren't executed THAT often to warrant exposing four internal
functions.  Besides, I'll be hacking on them and need everything laid out
cleanly.  Should somebody complain, they can go change them to __fastcall or
something.

80bd1bb4e4 engine: make neartag accept a sprite-blacklist function and use it in sector.c.
Internally, the last argument to neartag is now a pointer to a function
  int32_t (*blacklist_sprite_func)(int32_t i),
which is supposed to return 1 if sprite[i] should NOT be considered for hitting.

This is now used in the hard-coded neartag() calls in sector.c, but not in any
way in CON (there's neither a C blacklist function provided, nor is there a
possibility to define one in CON).  There, all sprites with picnums >=1 and <=10
(i.e. the effectors) will be blacklisted.  This remedies problems where such
sprites would get in the way of switches.

Note that a whitelist approach (only consider a predefined set, namely those
picnums which will be checked afterwards) has back-compatibility implications
since people may have used e.g. lotagged window sprites to cover a switch.

Also, the >=1 to <=10 range is [sic] (the static, not dynamic values are used),
since anyone redefining effector picnums is clearly out of their mind.

30e16fe7bb When loading a map in-game, clear TROR wall members corresponding to up/down links.
I find this cleaner for two reasons.  First, lotags won't get in the way of
neartag(), so that doors and switches near constrained TROR walls can be
pushed.  Second, this removes the information leak so that CON coders aren't
tempted to read that values directly before a proper API for that comes along.
When writing out a map in-game (e.g. with dndebug), restore the respective
members so that it can be loaded in the editor again.

00b852fe37 EDuke32: When in menus, always draw a black (33%) translucent background.
Internally, there's a new function fade_screen_black() that implements the
fading more efficiently than calling rotatesprite for classic, and uses
tile 0 (assumed to have at least 64x32 size) in the GL modes.

The black background of the user map selector is still done with rotatesprite
and tile BLANK in every renderer.

a6158ac3f6 Fix building with GCC 4.6 link-time optimization.
It looks like GCC doesn't honor the 'used' attribute with LTO. This is
"fixed" by declaring the variables in question with external linkage
(i.e. removing the 'static').  I consider such behavior a GCC bug, though.

d0acd40ff8 Inreased debugging level for catching oob accesses to 'main' arrays.
If enabled, this makes the following arrays be allocated statically:
spriteext, spritesmooth, sector, wall, sprite, tsprite, while
necessarily disabling the clipshape feature (because it relies on
setting sector/wall to different malloc'd block temporarily).

To compile, pass DEBUGANYWAY=1 in addition to RELEASE=0 to 'make',
and it's really only useful with CC=clang, of course.

480690aa1d Fix the Polymer hitches first encountered with Parkade.
The cause was a combination of many factors. First, Polymer requires the
start-drawing position to be inside the sector to draw (deviations lead to
incorrect drawing).  This was violated by the game, because it interpolated
the current and next tic position without updating the sectnum, leading to
inconsistencies especially when passing through narrow sectors.  Polymer
worked around it by doing an updatesector() each frame, however this works
poorly for maps with overlapping geometry such as SoS or RoR.

The solution to this is to add a new engine function,
updatesector_onlynextwalls(), which searches the sectors (via nextsector)
in breadth-first fashion instead of from 0 to numsectors-1, like updatesector
does when it fails for the *immediate* nextwall neighbors.

Internally, the breadt-first search helpers are moved into the engine.

b3474c75b2 Rewrite the savegame format in terms of the generic saving/loading system.
This makes savegames practically the same as the initial snapshot of a demo.
Saves are now named 'dukesavX.esv' (demos: 'edemoX.edm').
Additionally, many changes that couldn't/needn't be cleanly separated are added
with this commit:
 - make spriteext_t have the same size across 32/64 bit platforms (actor_t partially)
 - prevent saving/loading in MP games (it certainly didn't work and still doesn't)
 - it's time we start using assertions! Define NDEBUG for releasse builds.
 - reset savegame major and minor versions (we have a new magic string, so no conflict)

45bcc11f46 Batch-insertion of many points at once using line drawing and ENTER.
When having drawn N new points (and having one 'free') and pressing
ENTER, the N line segments between the new points are checked one by
one for intersection with every non-grayed-out wall and a wall vertex
is inserted at every intersecting point.  This may be viewed as a
prerequisite for a 'cutter' style tool.

2415b03c79 Support for drawing 'island sectors' for TROR/classic (and with limited
functionality, Polymost).

The new feature can be enabled/disabled with the 'r_tror_nomaskpass' cvar.

The basic idea is that when drawing lower or upper levels, a first pass
is performed that ignores all red walls for which the TROR nextwall link
'towards' the viewer arrives at a red wall.  Thus, in the worst case, there
can be up to twice as many rendering passes now (when it is discovered that
the no-mask-pass isn't different that what would be drawn with the ordinary
one, the latter is skipped, since we've already drawn all needed geometry).

Hovever, this kind of multi-pass splitting is only suitable for simple scenes,
like the upper subway in the TROR test map.  In particular, multiple islands
shouldn't 'see' each other.

Two issues are worth mentioning: first, care needs to be taken for translucent
ceilings or floors, since drawing them twice isn't the same as drawing them
once. This is done for classic, but not for Polymost.  Second, sprites (which
are always drawn _after_ the geometry for a given pass) are still clipped to
the geometry of the ordinary pass, resulting in their disappearance from
certain angles.
--

Additionaly, a change made it into this commit that fixes redundant collection
of sprites in TROR:classic/Polymost.

5d79003e60 Take a stab at hidden model switch handling. There are at least two ways by
which switches have been hidden in the original and user maps. One is to make
it face a wall, and another is to 'embed' it in e.g. the floor, like the
monitor with the burning fuse in E4L1. Both kinds show up when the switches
are rendered as models, revealing the secrets that the mapper sought to hide.
My proposal, implemented in this commit, is to apply a heuristic for such
switches at premap and make them invisible (set cstat bit 32768). The
conditions are re-checked during the game in case there is a switch coming
out of the floor, for example. A new spriteext bit is used for this feature.

8b5761c14d My first commit!
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.

ef61e48c25 Patch from Hendricks266 and whatever changes happened to be in my tree. I hope they work ;)
"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."

243e50db4b Insert two divide-by-zero checks that seem to fix the overhead map crash, but only with NOASM=1. Fix a couple of Mapster32 bugs and prettify some code there. Fix EDuke32 bug where the demo system overwrote boardname[] while using the file picker, making navigation between directories impossible.

64e22b9c6f * Support for entering names instead of numbers in various contexts (TAB-autocompletion included): first, when querying for a tile number, and second:
* Tag labeling system for 'link'-type tags, including saving and restoring the tag labels to a separate file '<mapname>.maptags'.  Whether a tag is eligible for linking, is determined by a hardcoded (but extensible via m32script) function.

a2b3b6006c * Correctly draw floor-aligned sprites with non-power-of-two textures in classic renderer.
* Sprite cstat 2048 ('use own shade', [N]) now works more or less. (Issues may arise when combined with sector light effects.)
* Begin work on 'smart' tag labeling system for Mapster32.  Right now, it only displays a '+' after tags with linking semantics.
*

1fdafcdad6 Cleaning out my tree... mostly internal changes. Adds workaround to disable texture compression with the crappy fglrx driver on Linux, fixes FIRE sprites so that they don't render at their sector's floorz all the time, changes CON compiler around a bit to use a loop instead of calling C_ParseCommand() 10 million times.

46964b322b * Lazy hightile loading in Mapster32 tile selector (first display all as lowtiles, then load each one while allowing movement)
* Consolidate the various, slightly different, methods of bounding a sprite between a sector's ceiling and floor into one common function
* Fixes for accumulated bugs: shade preview, r_shadescale_unbounded, and a couple of unreported ones
* Yaks, gnus, and bisons...

06afc4dcc5 * Comment out some practically dead code (rendmode 1 and 2, pcx screenshots), cutting some 8k from the release binary.
* Refactor two nearly identical chunks in polymost.c into one function in the hope of getting some more, but interestingly that did nothing at all. At least it's more readable this way...
* Commit, but don't enable, code for writing PNG screenshots (I'm tired of converting them every time). Requires libpng which in turn requires zlib.
