DOOM/linuxdoom-1.10/TODO

- create Web repository for sources, patches,
  news, and pointer to doom-editing mailing
  list.

- get DOOM Public License from id

-----------------------------------------------

- remove m_fixed, switch to floating point
  More stable, and prolly even faster.

- make SCREENWIDTH/HEIGHT work at startup?
  Well, the HUD/STBar stuff is tied to the
  scales implied by the graphics. Rather do
  GLDOOM and use texture mapping.

- fix aspect ratio?
  320x200 is nothing viable nowadays.
  A 320x240 base (4:3) would be a lot better.
  See above on width/height.
 
- limited look up/down by y-shearing?
  Prolly not worth it, rather switch to GLDOOM.

- switch to C++?
  The action function pointers have varying
  argument lists (no parameter, one, etc.).
  C++ doesn't like that much. A major rewrite.

- switch to doommain.c plus libdoom? Have 
  libref, libgame etc.?
  Another major rewrite.

- use XFree86 DGA, prolly not that much faster
  than MIT SHM, but allows for directly sampled
  mouse (and even freelook). Recommended for
  GLDOOM.

- put together an accompanying developer toolkit
  source distribution: DEU, RMB, BSP for Linux/X.

- move info.h, info.c, sounds.h, sounds.c and
  other data to a separate lump in the WAD,
  or into a libgame.so, to separate the 
  generic stuff (refresh, I/O) from the
  DOOM specifics.

- decide whether precaching all sounds is
  better than retrieving and releasing
  every so often. DOOM seems to do that
  frequently (8bit stuff, originally for
  DOS), and the Linux sound is 16bit
  (conversion in the mixing, requires
  some padding) - we prolly got the memory
  to spare.

- 16bpp CLUT. The lightmaps and the
  framebuffer could be changed to switch
  to 64K colors. Prolly better to do
  GLDOOM right away.

- remove checks for commercial etc., in
   non-essential issues (enabling PWAD's).

- change (simplify) determination of
   sky texture (done by game version).
   Explicit?

- remove all game version checks

- different handling of Demo - don't
   exit on "different game version"

- how about shareware/retail "You are here"
   intermission animation? Wasn't in
   commercial (DOOM 2).

- double shotgun in DOOM1, all weapons with
   shareware

- checks for required lumps. We need fallbacks
   for lumps that are not present, that is,
   default sounds etc. to be used instead,
   or removing THINGS w/o sprites etc.

- client/server? I'd suggest ripping off some stuff
   from the abandoned IBM WebView project

- Blockmap
   The BLOCKMAP lump might be (partly) redundant,
   as the BSP allows for clipping (except certain
   LineDefs that will not spawn Segs).

- LOS
   REJECT and intersection based LOS checking could be
   done using the BSP. In case of REJECT, certain
   monster AI special effects would be lost, though.

- correct handling of height in collision. This is
   not done, and the checks are scattered around in
   many places. It does require handling of "player
   on top of monster" situations, too - we have to 
   make sure the players falls off far enough to
   avoid getting "stuck in monster".

- remove obsolete menus (Detail. Music Volume?)

- clip explosion range damage (and sprites) using
   REJECT? That is, if one Sector/SSector not
   visible from the other, do not apply damage,
   not render sprite if player in other sector.
   Hmmm - explosion behind small pillar might not be
   visible at all, but do we care?


- Ungraceful and untimely demise of Linuxdoom (core
   instead of I_Error) will leave idle sndserver
   processes in your system, blocking /dev/bsp.
  A timeout on lack of input for "sndserver"?

- threaded sndserver? SHM mixing buffer?
   Or internal, timer-based?
