Doom Legacy Changelog

1.48.8 SVN1568 (2020-12-19)

FEATURES 1.48.8

  * Sky generation has gotten a Vanilla setting. Sky drawing (software
    draw) now puts a solid texture above and below the sky, and no
    longer tiles the sky. The OpenGL sky draw has separate sky draw
    behavior.
  * The mouse2 serial support has been expanded to handle PC mice,
    MouseSystems mice, and PS/2 mice, for SDL and Win32 ports. The PC
    and MS mice have been tested. If anyone has found a way to route a
    PS/2 mouse, possibly on USB, to a serial port input, please let us
    know.

BUG FIXES 1.48.8

  * A savegame buffer overflow was fixed. An overflow prevention test
    had been misplaced. such that it could be avoided in some
    conditions. Fixes BUG 0667.
  * Cleaned out some of the accumulated cruft in sky drawing. Fixed sky
    tiling, and then made changes to prevent sky tiling.
  * Changed the software mode sky drawing to TM_picture format. This
    eliminates the line artifacts that were drawn above and below the
    sky, and restores the vertical alignment.
  * Limited the software sky drawing to the texture, so to not tile the
    sky draw. Created a skytop_flat for above the sky, and a ground_flat
    for below the sky. These are drawn when the viewed sky exceeds the
    bounds of the sky texture. For now, these flats are created as solid
    textures. Hardware draw has a separate sky draw behavior.
  * In the case of 200 or 240 sized sky textures (Heretic and Legacy
    substitutes), fixed the texture sky height so that the correct size
    TM_picture is created. Fixes BUG 0668.
  * Changed the freedoom wad names, avoiding doom wad names as that was
    conflicting with doom2 gamemode. Freedoom: "freedoom2.wad",
    "freedoom.wad", and "fdoom2.wad". Ultimate freedoom:
    "freedoom1.wad", "freedu.wad", "fdoomu.wad".
  * Fixed BUG 0670, Monsters mysteriously disappearing, moving large
    distances into the void space.
    This bug was introduced in the moonwalk patch (SVN 1540) by copying
    the opposite direction calculation code from PrBoom. This was done
    in an effort to reduce differences that might lead to bugs. It
    replaced a table lookup implementation. However, the PrBoom
    calculation must be guarded against the value DI_NODIR, which the
    table implementation could handle inherently. Without that
    protection, an olddir of DI_NODIR introduced a direction of 12 into
    the logic, which can only handle directions of 0..7, with NODIR=8.
    Several times a game that 12 value would survive long enough to get
    used, which would be expressed as a wild walk movement.
  * Improved the large blockmap handling to deal with more issues of
    blockmap overflow in the presence of zennode blockmap compression.
    It can now handle more maps of the Lost Civilization wad, although
    some other issues are still present.
  * The mouse2 support was found to be disabled and missing for the SDL
    port. It has been fixed, and expanded to handle PC mice,
    MouseSystems mice, and PS/2 mice, for SDL Linux, SDL Windows, and
    Win32 ports. Fixes BUG 0669.
  * Made LOGMESSAGES work again, which writes debugging logs. Release
    binaries do not have this code. If DoomLegacy is compiled with
    LOGMESSAGES enabled (doomdef.h file), a log.txt file will be
    produced. This is currently enabled when compiled with DEBUG.
  * Fixed the overlapped string copies detected by GCC 10.
    Fixes BUG 0671, Michael Bäuerle.
  * Reduced warnings when compiling with GCC 10. This was mostly due to
    signed char being used as an index, which may cause problems on some
    platforms. Fixes BUG 0671.
