Moved quantization out of the draw code. The laser is now quantized once
per frame, and the segment data is used for both collisions and
rendering. Player motion is now accounted for as well, preventing
phasing through thin lasers. The overall result is more precise *and*
faster collision detection.
* lasers: new SDF-based renderer (WIP)
* lasers: tweak sdf_apply shader
* lasers: fix incorrect rendering at 'unlucky' resolutions
* lasers: optimize rendering of multiple lasers
Try to coalesce render passes as much as possible
* lasers: fix warning
* lasers: move rendering into a new file
* lasers: correct "time" coordinate mapping for texturing
* lasers: wrote a novel about laser rendering [skip ci]
* lasers: fux tpyo
* remove references to old laser shape shaders
* lasers: fix some rendering edge cases
* Smarter generic entity macros
The list of "core" entities is now defined in one macro, and hardcoded
_Generic dispatch tables are eliminated
* Get rid of "custom" entities
All entities are now "first-class". The list of known entity types has
been moved to known_entities.h. The system no longer needs to know the
definition of all entity structs.
* Refactor guts of ENT_BOX/ENT_UNBOX
Made the functions inline, Box::ent is now a proper pointer type (but
please don't use it directly), ENT_UNBOX returns NULL if the box is
"empty" (references NULL entity)
* Merge TASK_BIND_UNBOXED with TASK_BIND
* s/YoumuMyon/YoumuAMyon for consistency
* More lenient collision detection
* More rounded corners
* Add a task for laser charging (not used yet)
* Make snow halation lasers not use the logic rule
- Logic rules to be removed in favor of tasks
This also introduces `float32`, `float64`, and `real` typedefs to be
used in place of `float` and `double` later. `real` is for game code and
other places where we don't particularly care about the precision and
format of the underlying type, and is currently defined to `double`.
`float32` and `float64` should replace `float` and `double` respectively
* WIP premultiplied alpha
* WIP color API rework (doesn't build yet; lots of things left to convert)
* convert everything remaining to new Color api except stage*_event.c files
* convert the stages to new Color api. builds & runs now; still many rendering errors
* fix the bullet shader for premultiplied alpha
* fix masterspark, graphs and stage 1 fog clouds
* fix marisa_b and most of spellcards
* Add deprecation warnings for BLEND_ADD and PFLAG_DRAWADD
* fix a segfault in stage 6
undo accidental earlier change
* fix text_hud.frag.glsl
* fix scuttle bg and remaining stage3 BLEND_ADDs
* fix marisa laser opacity
* hacky fix for myon
The old implementation relied on alpha being stored inside p->color. In
premul alpha this doesn’t work and functions like color_set_opacity
can’t solve this i think.
So I tried messing around with it until it looked somewhat similar.
* fix marisa_b stars
* remove color_set_opacity i overlooked
* more plrmode blending changes
* fixup additive blending in stage 1
* various premultiplied alpha fixups for bosses and enemies
* stage 2 premul alpha fixups
* stage 4 premul alpha fixups
* stage 5 premul alpha fixups
* stage 6 premul alpha fixups
* make lasers also use the PMA blend mode
* remove PFLAG_DRAWADD and PFLAG_DRAWSUB
* fix remaining PMA issues in menus
* lame extraspell bg workaround
* fix item alpha
* make marisaA lasers look somewhat like in master
* fix marisaA bomb background fadeout
* fixup various r_color4 calls
* fix myon
* remove dead code
* fix use of BLEND_ADD in player death effect
* fix myon shot trails (broken on master as well)
* fix myon shot fade-in
* extend the sprite shaders custom parameter to a vec4
* fix youmuB stuff and make it look somewhat better.
the code looks even worse though.
