ui
- editor ui
  - port imgui
  - entity explorer
  - level editor
  - data window
  - assem explorer
  - timers
  - use reflection to make ui
- game ui
  - text
    - port the text rendering code
    - batched rendering
gameplay
- a* pathfinding
  - very basic pathfinding
  - actual a*
  - a* up / down slopes
    - a* down ramps doesnt work yet
    - cant go off one ramp onto another
      - because wp.level_idx is same, need to do floodfill or some to check for that case and then use game_a_star_pathfind_levels() multiple times
  - proper f-cost
  - doesnt always take the shortest route
    - i think happens when walking back route through closed_arr
  - check having two ramps after one another
- player chars
  - multiple player chars ( 3 probably )
  - switch
  - ??? move to pathfinding result (actually play out result at end of turn)
- enemies
  - stationary
  - ai
    - simple
    - more advanced idk
  - show their turn
- [o] combo-moves
  - basics
  - jumping off other player chars
    - curved line
  - tackle/kick/etc. enemies
  - carry enemies/player chars ?
  - push enemies/player chars ?
  - [.] interact with environment
    - push buttons / pull levers / etc.
    - bounce pads / trampolines
    - push blocks / obstacles
    - mines / bombs that trigger upon walking on them or f.e. attacking near them
  - ...
  - show moves
    - better path drawing not using debug_draw
    - paths
    - curves
  - limit the amount of moves chaned together in one turn
- turns
- differrent tile types
  - regular
  - slopes
  - ladders / climable
  - ice
    - when on ice go straight until not on ice anymore ?
  - breakable
- mouse picking (id-buffer)
  - select between player_chars
  - use mouse-picking when setting the path
graphics
- vulkan, bgfx or google filament ?
- make google filament wrapper
- make renderer forward not defferred
  - transparency
  - graphic effects
    - ambient occlusion
    - shadows
    - bloom
    - subsurface scattering
  - special stuff
    - current player-char outline
    - water shader
    - leaves / bushes / vegetation
core
- custom asset formats
  - texture
  - mesh
- batched / instanced rendering
- particle system
- proper asset streaming / loading
- serialization
  - map
  - chars position
  - enemy layout
- different hdri for reflections and bg
- proper debug_draw_update() proc drawing all registered debug-draws
- make debug_draw_path/curve() also be abled to use gl.LINE_STRIP
game art
- decide theme
  - fantasy
  - sci-fi
  - steampunk
  - dieselpunk
  - solarpunk
  - horror
  - lovecraftian
- decide style
  - stylized pbr handpainted
    - normal + handpainted normals
    - normal + handpainted albedo
    - both
  - stylized pbr ( overwatch )
  - stylized pbr ( arcane inspired )
  - handpainted
  - collect ref images
  - make pureref reference board
- make level art
  - export level as fbx/obj/etc.
- make character art
upkeep & organisation
- stack trace
  - dump stack-trace ( core:debug/trace -> only works on assert not crash )
  - try dump stack trace ( doesnt work )
- factor out gameplay from main.odin
- hot-reloading
- factor out code into packages
  - assetm
  - data ?
  - util
optimization
- pass data using context or as proc args to avoid cache misses
- make game_a_star_pathfind() use temp_allocator
- find all allocations and check if context.temp_allocator could be used instead
- bindless textures ones i have vulkan renderer

buggs

debug_draw_mesh() rotates around center (0, 0, 0) not pos, see main.odin
not freed in main.odin -> 231: data.player_chars[data.player_chars_current].path = make( [dynamic]waypoint_t, len(path), cap(path) )
not freed in game.odin -> 514, 538, game_a_star_pathfind()
booted up blank screen and infinite loop or some on laptop [23.12.24|00:50]
after sleep deprivation
- laptop no longer 160-220 fps now 15-30 fps, PS: dafuck did i do ???
  - added text_draw_string() which is unbatched
  - ???
- screen output buffer wrong size on startup -> prob. gl.Viewport()
- now just sometimes starts in fucking blank
