What changed in EDuke32, build by build

most problems where sprites appear to be drawn through walls.

First, if we're in Polymer, don't precache tinted tiles that have a highpal for that certain pal. Second, don't precache tiles for palnum 251 (the last non-reserved one, which is used as a crosshair pal). Assuming that there are no other tints, this cuts the initial precache time and cache size on disk in half.

Makefile: remove ebacktrace1.dll on 'veryclean' target

This way, crashlogs will really be appended. Additionally, print a time at the end of each backtrace. winlayer.c: load ebacktrace1.dll instead of the old one Makefile.common: when building with DEBUGANYWAY=1, don't omit frame pointers This will let us get a stack trace for crashes with the release build code.

exclude grayed out walls.

./configure --disable-vp8-encoder --disable-multithread Also add VPX/VP8 headers for an easy build on Windows. Throw in the necessary lines into the Makefile but do not enable VPX support yet.

- when pasting to walls or maskwalls, the following user bits are kept now: 4 (top/bottom alignment [O]) 1+64 (blocking, hitscan) 8+256 (x/y-flip) - print '(one-sided)' when pressing Shift + ([B] or [H]) on a wall

before, and additionally a mode that doesn't clip against masked walls and sprites.

uint64_t gethiticks() and gethitickspersec(). For SDL 1.2, the timer has the same resolution as getticks (1000 Hz). For Windows and SDL 1.3, the resolution of the underlying perf-timers is used. The only user of these functions right now is some TROR on-screen debugging code. Revert an earlier change regarding r_preview_mouseaim. We can't do the check because editstatus is set later.

the additional rendering pass - Remove r_preview_mouseaim cvar from the game, since it's only for Mapster - sdlmusic.c: (Failed) attempt to fix a call of waitpid() with a non-existent process ID in the external MIDI playing code. I think there's a race there...

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.

- remove 'imageSize' global which was always yres*bytesperline and only used once - some clearbuf() -> Bmemset() because I find the latter easier to read - remove some clearbufs to 0 of some global arrays on init

always like this now: ExtUninit -> (writesetup, misc.) uninitengine -> (uninitsystem -> (uninit timers, mouse, ...)) exit() Some paths still lead to a plain exit(), like failures in cache1d.c or mdsprite.c

in any renderer because it's drawn with the software one... Also add a hack to make Polymer realize that viewscreen tiles can change each tic so that they don't show a static image anymore.

with other than base levels, since the y*most arrays are copied there later.

handled could lead to a bunch whose floors and ceilings covered different areas. A fix for the reduced functionality arising from this change is underway. - Rewrite a small portion of code using yax_vnextsec() in game.c.

dealing with sectors on the two sides of a bunch. Make yax_globallev and yax_globalbunch variables non-static. Rewrite a TROR-related bit in the engine code using the new function.

effects: 1) Mouse turning works with SDL 1.3 2) The mouse pointer can't leave the window area with the console up, so that focus always stays with the application 3) Menu selection using the mouse doesn't work. Not dramatic IMO.

is present (like in E4L1). Also sneak in a trivial change in cache1d.c

fix two issues with signed integer overflow. One is related to clipping and the other to Polymost mouse-picking for overlong walls. Many more remain especially in the 8-bit rendering code, but I expect many of them to be intended.

is to remove a couple of 'inline's for functions with external linkage, which seems to be a GCC convenience.

name into m->head.nam after loading (but before preprocessing for Polymer)

whenever we change to another renderer etc. and define it for the game and editor. The purpose of the function is to clean up references to Polymer resources like lights. This fixes 1) all lights becoming spot lights in the game and 2) an issue with maphack lights in the editor (can't recall which exactly).

Specifically, now also consider the sprite tile's yoffset, and fix an issue when a tsprite got duplicated 'toward' the viewer. Also add a couple of tests in trueror1.map.

hold file lengths is certainly very frownworthy.

This makes the latter also correct when testing a map from the editor.

With script_expertmode enabled, SHIFT-BACKSPACE clears the upwall link and CTRL- BACKSPACE the downwall link. These functions are useful because the automatic nextwall determination code sometimes gets it wrong (not corrupting anything) or if you want to vertically displace a sector attached to a higher or lower level. Also add the exploding ceiling example to the TROR test map.
