* Added in fca846272e to deal with signed adjustments but its just not needed.
* Made better use of `binangle`/`fixedhoriz` class getters and setters than before as well.
Since these do not fully get processed sequentially the contents need to be preserved until needed.
This required getting rid of the global tsprite array. Polymost still uses a static vatiable, though, but this is only accessed in polymost-exclusive code.
* Doing this in `renderView()` unconditionally isn't correct as it can lead to a double adjustment if `p->spritebridge == 0 && p->newOwner == nullptr`.
Like for Blood, the Polymost-only code has been moved aside.
Closer examination of the preparations the engine is doing for rendering SE40/150-portals shows that all this was merely done to avoid glitches with a two-phase rendering setup - nothing of this will be needed for doing it properly.
They can just be treated as run-of-the-mill stacked sectors. when using hardware rendering capabilities for clipping.
* Primary issue was call to `renderSetAspect()` within `setdrugmode()` wasn't mulscaling with `viewingrange`.
* Changed `setdrugmode()` to `getdrugmode()` to return `p->drug_aspect`. This is so `renderSetAspect()` needs to only be called from one place only.
Storing this in the player_struct is pointless and a relic from having to use real hardware palette switches.
With this now just being a translation index being passed to the backend it can be cheaply retrieved right when used and nowhere else.
Also making some changes to how RRRA's psychedelic cactus handles the projection. This fixes issues with occasionally passing a bad matrix.
* Struct made up of binangle class units.
* Create signed clone of binangle for use with look_ang and rotscrnang.
* Append currently outgoing function names with `2` at the end to avoid conflict.
* Started with the most complicated game first.
* Struct made up of fixedhoriz class units.
* Append currently outgoing function names with `2` at the end to avoid conflict.
* Blood had this right. It makes sense that the horizon be based around as it's easier to work with.
* Removed all associated game math to deduct default horizon of 100 when doing weapon zvel etc, meaning actual horizon can just be used.
* Re-did return to center function to work on the already converted pitch. Return speed should be 1:1 with previous code.
A nearly typical problem of this code. Not all relevant properties of the camera target were changed at once - there was a two frame discrepancy in which the camera pointed in some undefined direction after the change.
Fixes#15
* Remove fix16.h/cpp and utilise library from m_fixed.h.
* Extend m_fixed.h with two inline functions for int to/from float operations.
* Replace fix16_floor operations with those from xs_Float.h
* Replace multiple Q16.16 conversions from 0 to just be 0.
* Replaced all found in-game bit-shifts and multiplications/divisions with inline functions from m_fixed.h
* Replaced many casts of FRACUNIT as double in SW's panel.cpp as it is converted to double by way of type promotion.
* Fixed missed precision fixes in SW's panel.cpp where some types weren't declared correctly.
* Replaced 100+ `Cos()/Sin() >> 16` operations for Blood with inline functions `CosScale16()/SinScale16()`.
Timer values in interface code are undefined, these should not access anything that changes at real time.
Also use smoothratio to do the calculation in frame time, not tic time.
This timer only gets incremented by the main game ticker when the playsim is running.
This timer gets used for all playsim-related timing and animations so that these are decoupled from imprecisions in the global timer.
In particular this means to remove the option to disable widescreen aspect ratios. The way this was handled makes no sense with the current render backend.
The aspect ratio code will have to be redone entirely to properly obey the backend's settings.
* Build timer still requires initialisation due to multiple `timerSetCallback()` that still need to work.
# Conflicts:
# source/core/menu/menu.cpp
# source/games/duke/src/game.cpp
* Current setup was broken and unusable.
* Fixed interpolation issues.
* Only call `GetInput()` at frame-rate when `cl_syncinput` is 0.
* Create `oq16look_ang` and interpolate it for enhanced smoothness.
* Always reset `horizAngleAdjust` and `horizSkew` in `processinput_d()`.
* Don't pre-scale `sb_avel` in `processinput_d()` and `processinput_r()`.
* Promote `p->angvel` from short to fixed_t.
* Don't descale `sync[snum].q16horz` in `processinput_d()` and `processinput_r()`.
* Ensure `false` bool is provided to `sethorizon()` call in `processinput_d()` and `processinput_r()`.
* Reset `p->q16angvel` in `resetplayerstats()`.
The checks for game pause were totally inconsistent, so now there is a utility function that tells whether the game is supposed to run or not.
pause can also take 3 values now - 0 for no pause, 1 for pause from opening the menu or console or 2 for hitting the pause button.
