[anarch.git] / TODO.txt

general:

- Port to OpenDingux.
- Rewrite python scripts to C (faster, less bloat, fewer dependencies).
- run on raspbery pi
- mod: terminal messages (when standing near terminal, a message appears)
- option for turning off the status bar

level ideas:

- outline:
  1.  City, player sees the big Macrochip building (a smaller one) in the
      distance and has to get to its entrance. Beginning of the level is linear
      and serves as a tutorial, things like exploding barrels or acess cards are
      explained.
  2.  Inside Macrochip smaller building. End leads to an elevator that goes
      under the ground.
  3.  Warehouse:
  4.  Factory:
  5.  Small boss level:
  6.  City, player is on the other side of the smaller Macrochip building, the
      level partially overlaps with level 1, but the player can now go further.
      Big Macrochip HQ (skyscraper) is seen in the distance, player has to get
      to its entrance.
  7.  Inside skyscraper, 1st floor.
  8.  Inside skyscraper, higher floor.
  9.
  10. Final boss level: on top of the skyscraper, player climbs up in a spiral
      towards the roof. There is a boss (or two) on the top with a few smaller
      ones, the exit is blocked by a lot of trapped warriors which the player
      has to slowly kill, which means he has to first get rid of the other
      monsters.

- Long section under squeezer, player has to run and keep hiding in side rooms   DONE
  to not get killed.
- Elevator with 4 exits, on each world side.                                     DONE
- Teleport to a football stadium outside?                                        DONE
- Key to door that need to be unlocked can also unlock a door in previously      DONE
  visited area which will just hide secret.                                      
- text on the wall -- some letter can be create- text on the wall --             DONE
  some letter can be createdd
- Enemies can be placed on a single square higher fround to prevent their        DONE
  movement.
- Many teleports at place A and one teleport at place B, giving a low chance of  DONE
  reaching B: player has to gring teleports until randomly lands in B.
- Underground storage level start: be at the bottom of an elevator pit.
- ceiling with "holes" through which sky (background) can be seen -- can be done DONE
  by having the ceiling texture set transparent and then alternating ceiling and
  no ceiling
- boss level: skyscraper top, player goes upwards in a spiral along the OUTSIDE  DONE
  side of the skyscraper
- two levels could partially overlap, e.g. level one, a city, could overlap      DONE
  with a later city level, the player could recognize he's e.g. on the other
  side of a channel or a wall that he was before
- invisible maze                                                                 kinda
- wall made of elevators (or squeezers), serving as a big auto-opening gate      DONE
- a key spot to which the player can only get by jumping from a distant high
  elevated place
- player has to jump from one elevator to another, which can only be done when   kinda
  they're both moving down

- server room                                                                    kinda
- window (low unpassable ceiling) through which finish can be seen from the
  start location of the level
- three locked doors in a row at the beginning of the level, the player has
  to go to three different locations for each key -- a "hub" level
- office building                                                                kinda
- plasma bots guarding a big stock (store) of plasma ammo
- warrior (enemy) right before the player at the start of the level
- T-shaped corridor in which two rocket-firing enemies stand facing each other   DONE
  so that the player can kill them by stepping between them, letting them fire,
  then stepping back, making them kill each other
- enemy trapped between barrels
- teleport that leads to another teleport which is on a single high elevated
  square from which the player has to jump down and won't be able to return,
  making it a de-facto one-way teleport
- teleports placed so that the player can shoot himself with a rocket or plasma  DONE 
  (for fun)
- exploders in a maze, hiding behind corners
- teleport leading to a center of big room full of enemies                       kinda
- easter egg -- a level that looks funny on the map, e.g. forms a text or a      DONE
  picture
- squeezers with low-elevated base (a hole), on a side of a corridor -- if the
  player is curious and jumps in, he's doomed to die -- perhaps there can be
  many of them while one is in fact an elevator, which the player has to spot
  and take in order to advance
- bullet-shooting enemies behing windows (low ceilings) in rooms that can't be   DONE
  reached
- locked door that cannot be unlocked at the beginning of the level as a         DONE

  level wall textures and then sing it for "fake" doors
- invisible bridge (perhaps not straight) made of blockers (invisible walls)     kinda
  over a hole, leading to an easter egg
- start of level: a corner blocked by an invisible wall, to indicate entrance    DONE
- small pyramid from diffetently elevated floor tiles

bugs:

done:

- try to remove the debug flag (-g1) from compiler and see if it decreases size
- compile on BSD and WinShit
- Profile, epsecially Pokitto, small periodical tearing can be noticed (some
  periodical updates probably).
- Compile Pokitto overclocked version.
- Refactor.
- Check grammar in source code.
- Polish the emscripten version (is basically unplayable on phone, horizontal
  mode doesnt show whole screen etc).
- Polish controls (bindings, mouse sensitivity etc.).
- Polish weapon switching, maybe add a key to switch to previous weapon?
- add headbob
- Switch music tracks when level starts?
- SDL: handle the quit signal so that the program can be closed by closing the
  window.
- On Win$hit builds display an anti-windshit text, by macro.
- save/load (optional):
  When a level is finished, the state at the beginning of the next one (health,
  ammo, time, ...) is automatically saved and can be restored via load option in
  the menu. This save as well as some other things (game progress, inagme
  settings, ...) will be preserved even adter game restart if the platform
  implements a saving function.
- more levels
- port to GB Meta
- "Smart" weapon switching. e.g. don't auto switch to knife unless necessary, or
  auto switch to a weapon from knife if ammo is picked up.
- option for vertical auto aim
- add blinking
- make zBuffer 8bit only?
- texture coords of floor walls should start from the floor? NO, CAUSES ISSUES
- vertical visual noise when standing on elevator
- sprite positioning inccuracy
- try to compress images: store images as 4 bits per pixel + 16 color palette
  (subset of the 256 color palette), check if performance stays ok
- custom font
- make barrels explode
- enemies
- weapons
- sounds
- add enemy moving/dying sound
- create tables for monster and weapon stats in constants.h and read from that
  instead of cheking with ifs
- check if monsters are hit by bullets from completely up close
- menu
- GUI
- make enemies not move through items:
  create a 2D bit array saying at which squares there are colliding items, then
  check collisions for both player and monsters against this array (elevate
  these squares for collisions only) -- will also be faster
- more level prop items
- let player start with 100 HP, but allow for collecting a higher amount, e.g.
  up to 150.
- limit maximum ammo amounts
- boss (the last one killed) should drop key card, for boss levels (hardcode).
- music:
  Probably just one long music track playing over and over -- KISS. The frontend
  could have a callback function play_music_bar(n) which would be called by the
  backend, the music track would be in sounds.h.
- easter egg(s)
- level 2D map (with revealing, bitmap), special key for quick displaying map
- add universal corpse sprite?
- if space left, try blurring (lerp) the level background, see how it looks
- replace textures in distace with constant color for performance (setting)?
- enemies close to a wall often don't get drawn
- Architecture change: make platform files compilable and move main.c to game.h
  (so that pokitto is .cpp, GB is .ino etc.).
- Bytebeat is bugged on Pokitto, outputs different values than on PC. Fix this.
- Player jumps higher on lower FPS, is able to jump on 4 squares. Also check the
  distance jump.
- disable transparency for walls for performance (setting)?
- On desktop, SDL makes a high-pitched noise because of DC offset. Maybe put an
  average DC offset for each track into assets so that music player can use this
  to normalize the track?
- Player is sometimes squeezed to death in door (appeared in level 9).
  Investigate, fix.
- Add option for advanced head bobbing which will also shear the camera along
  with offsetting it.
- compile with different compilers (gcc, clang, musl, ...) and settings, make
  a build script that creates multiple binaries (with different combinations of
  compilers and settings)
- High pitch noise in SDL music AGAIN!
- Add SW buttons to emscripten version so that it's playable on mobiles.
- When SDL level starts without moving the mouse, the camera sometimes rotates
  wildly.
- Player can be thrown inside a wall (by an explosion it seems), seems to happen
  near door. If this can't be prevented completely, automatically unstuck the
  player into a playable area.
- Try to recolor textures and give them a bit more of variety.
- Even if music is off, after turning on a few samples are played (also on
  Pokitto).
- At the beginning "FPS cant be reached" is always displayed.
- automatic tests: a frontend that will play the game, check the state, rendered
  frames etc.
- make SFML frontend
- Add FOV options. RCL doesn't project sprites with different FOV correctly -
  FIX!
- When selecting continue from menu, the player shoots - fix!
- FIX: running diagonally (forward + strafe) player can jump over 3 squares!
- add time slowdown constant
- On Pokitto/GB Meta sometimes after turn on the game starts midway loading the
  first level.

scratched:
- option for disabling wall transparency, for performance?
- weapon autoswitch: when a stronger weapon becomes available via picking up
  ammo, maybe it should automatically be switched to (could have disable
  setting)
- Ability to play SFX slower to e.g. give some monsters lower pitch?
- Force monsters that are squeezed (e.g. on door) to always move.
- try to make z-buffer 3 line instead of 1D, possibly like this (to keep
  performance):
  - at compile time selct X = power of 2 closest to vertical resolution
    (or something like that)
  - in pixel funct do something like
      if (pixel->y % X == 0 && pixel->y != 0)
        write to z-buffer
- open door by shooting at them?
- add jump pads?
- add "pletivo" transparent wall texture?
- make monsters die when squeezed?
- add robot deactivator item? (encourages "stealth" gameplay)
- optional graphics enhance: vertical wall shading ("ambient occlusions")?
- some monsters could reflect plasma, i.e. not be hurt by it, but reflect it
  back towards the player
- Port to ncurses?
- Port to some fantasy console?
