2ffdf3d0e1 - backend update from GZDoom. 
Mainly quaternion math and sound system cleanup.

4d6920e80b - fixed failiure to initialize the ambient tags array. 
Also adding range checks to all places where it gets used. This is from CON code so proper values are never guaranteed.

2290f05dcb Revert "- Use std::fma() in the interpolation code." 
This reverts commit ff7e0afa6f.

On Visual Studio with precise math, which is our main target this generates a very expensive function call instead of optimized assembly which renders the function's purpose ad absurdum.

ff7e0afa6f - Use std::fma() in the interpolation code. 
* From everything I've read, this more accurate, can be ~5% faster and is heavily optimised on CPUs of the last 10-12 years.
* This homegrown solution can be removed for `std::lerp()` once we go C++20.

274899c9db - Get rid of useless lerp() function I added last night for lack of C++20. 
* We already have a generic linear interpolator that _I_ added, so let's use it.

8ec475aec8 - Replace clamped off tangent values with a linear interpolation of the player's pitch. 
* Gives a tangent-like ramping where it's noticeable without having to use the tangent at all.
* Had to do homegrown lerper since we're not C++20 yet.

a3dbfab54b - return some invalid but recognizable magic value when IntersectLines is being passed two collinear lines. 
This actually should check if the two lines are identical but since this is rather expensive and rarely needed it's better handled by returning a distinct value the caller can handle if needed.

e3254a8546 - fixed an edge case in cansee where an actor placed directly on a two-sided wall would fail to register that wall's back sector. 2022-10-30 16:51:37 +01:00

98e2fecd37 - another bunch of type conversion warnings fixed. 
the ones in the findplayer functions are not critical in singleplayer.
 2022-10-30 16:51:35 +01:00
Christoph Oelckers
902f8c9706 - silenced lots of warnings for deliberate type conversions. 
The ones in d_net.cpp are not in active code.

8e9ddf370c - rewrote getzrange 
Not using any old Build code anymore. Aside from the trivial stuff this uses code from Doom and SW instead.

bb6e12a2b1 - Eliminate remaining calls to TAngle<T>::fromBuildf(). 2022-10-25 07:07:03 +02:00

5d8cc1b4fc - Store all input speed constants as DAngle to avoid calling DAngle::fromDeg() all the time. 2022-10-25 07:07:02 +02:00

de70e802ec - downgraded all LGPL3 license headers in the backend to LGPL2. 
This had already been agreed by all involved authors, but apparently not all files were changed accordingly.
 2022-10-23 18:46:17 +02:00

2991bc752b - split out the pure math stuff from gamefuncs.h into a utility header in 'common'. 
Also did a bit of reshuffling on gamefuncs.h to group content better.

Christoph Oelckers
3352783be2 - added a Sum function to TVector familiy 
Duke uses this kind of distance check quite a lot so it makes sense to add it to the vectors.

d9f8ac4d2a - Convert automap's follow_x/follow_y variables into a proper vector. 
* Should have done this from the start, but anyhow...

059f15c786 - Refactor floatified vector math to use inline wrapped around TVector2's Rotated() method. 
* This will be used extensively in Duke and the other game as we finalise this conversion.

19d21555a6 - Duke: Change int_ang() usage in camera(). 
* This commit also restores the original method of incrementing the camera's angle that was replaced due to a hiccup/stutter where the angle suddenly skipped forward by 16 instead of 8, but with a fix from EDuke32. This avoids using 3x extra `temp_data[]` slots.

a22300fe01 - Blood: Replace some set_int_ang() usage. 
* A lot of this repeated code should be factored out into repeated blocks when all of this floatification is done.

2f896b859b - made the code mostly signed-char safe. 
This eliminates all char function parameters that are not really ASCII characters and casts all char argument to the ctype is... functions.

9275c14c9c - floatify SE18 handler. 
To store floars in temp_data without relying on map format conventions, the FixedTo functions were extended to allow custom precision.
