What changed in EDuke32, build by build

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.

so try and steal it back"), prevent calling IDirectDrawSurface_SetPalette() with NULL arguments, causing a crash. It's happened for me on Vista, when initially changing from 8-bit to 32-bit mode.

I didn't have much success in finding bugs using it, but it works out-of-the-box on my setup, so it may be useful in the future.

It turns out that with model interpolation, out-of-bounds frame numbers may be generated with thinned out models, so disable it until I can sort out what's wrong with it. Also, minor code cleanup.

Since the original source code release of Duke3D, there was a potentially dangerous hack where actor[].dispicnum was set to -4 to signal "this actor should not have a floor shadow for this moment" (it doesn't really work, if you ask me). Now, use another bit of actor[].flags for that purpose because setting any picnum members to negative values asks for trouble.

E.g. this should work correctly now: // FLY_BY, PIPEBOMB_EXPLODE, OCTA_DYING animsounds logo { 1 244 64 14 64 144 }

crashes. Usually, after loading a game, some wall tiles are tweaked depending on whether adult mode is enabled or not. If it's not, those wall picnums are replaced with blank or broken screens. If it is, they are restored from the wall's .extra member. Apparently though, Mapster32 leaves some .extra members floating around even after deleting a TROR nextwall link (it's used as the 'lower wall index'). Because MAXWALLS is greater than MAXTILES, this may produce out-of-bounds accesses and corrupt memory (besides setting wall tilenums to nonsensical values) later in the game. Other than that, the change only affects loading savegames created with adult mode OFF. Kinky TV screenies simply won't be restored then.

- Execute VM_ScriptInfo() when DNDEBUG is used.

certain situations (mostly cutscenes etc). This commit removes bit 1 from all flags that make it to setbrightness, the meaning of which is "don't actually update the palette". I have no idea what it was for and since the corresponding P_SetGamePalette() calls were from places like the mentioned cutscenes, I don't think it matters performance-wise.

This is in the similar vein as the set-palette deferring and it's this that fixes the low FPS in the radioactively contaminated area in AMC TC: Megabase (since setgamma() is called from setbrightness()). Again, update issues might be expected, but changing focus between EDuke32 and the desktop and back seems to restore the gamma settings properly on Kubuntu. Looks like X (or whatever above handles this stuff) maintains it on a per-application basis.

instead of shorts. This fixes their values' overflow in AMC TC megabase and probably a couple of other large maps.

in overhead map drawing code.

64-bit fixes

snapshots in the current development state now.

debugging, i.e. savegames and the like will break.

It was identified with the clearfrags rewriting, but not corrected.

if loading directly from file to state.

Various code checked for switch tiles in the following manner, for (ii=0; ii<2; ii++) switch (DynamicTileMap[sprite[i].picnum-1+ii]) { case SOME_SWITCH: ... } which blows for picnum 0. Now, we simply disallow it.

WGR2 SVN, so not sure where there's a tipping animation there).

(getzrange, hitscan, clipmove, drawmapview). They're reproducible with DNE1.3D; Since these angle values most likely come from CON code, my suggestion would be to bit-and all values representing angles with 2047 when setting the from CON, but I'd have to think about potential side-effects of doing this.

callback 'G_Polymer_UnInit'. - In astub.c, reset spritelightid to -1 when nulling the spritelightptr of a sprite (no crashes observed, just precaution) - In sdlayer.c, catch SIGILLs with our signal handler too, since illegal instructions are what the instrumented debug builds will execute when attempting to carry out an undefined (per C) operation.

one sector was filled and the 'clear bunch' message was displayed even if the operation was canceled.

The texture warping mode will need to be set depending on whether we're actually drawing a parallaxed sky or not.

This fixes the vertical (~1 texel wide) stripes that are especially noticable with tiled art skies and Polymost with r_parallaxskyclamp=1 or Polymer (which always uploads skies with repeating s and t coords). What constitutes a sky tile is currently hardcoded to be >=78 and <=99.
