The FixedMul() C implementation would produce off by one results,
causing constant desyncs on 64 bit builds and builds without an
ASM implementation of the function.
This is fixed by shifting instead of dividing, possibly avoiding
rounding errors.
This makes OpenGL stop using a specific function that doesn't really do anything for it anymore. It looks like it was used for a hack that would change the colour of polygons for the flashpal equivalent in DOOM.
I made it so ST_DoPaletteStuff doesn't set the flashpal in OpenGL as it already does its own hacky overlay and doing that would cause all the textures to be flushed more mid-level, it could be enabled for more correct flashpals, but they still wouldn't effect fog or lighting.
This means the palette will be set when going to the title screen, and twice when starting a map, (causing the OpenGL cached textures to also be flushed at those times)
Also move the Bouncy FOF sector special check above the FOF heights checking in P_CheckBouncySectors, because it means not having to waste time calculating FOF heights only for it not to be bouncy anyway :P
This means that, if the three paths are not the same, you should be able to tell if at least one of them has a file that just had a bad MD5. Most relevant for Linux peeps I expect.
Note: Untested as of writing
Set up similar to NiGHTS Mare linedef executors. Give a sector the "Race
Lap" sector type, tag it, then set the frontside x-offset on the trigger
line to the lap it should activate on minus 1. There are a few flags you
can check on the trigger line to modify its behavior.
- Normally the executor will only trigger if its exactly on the lap
specified. Check Not Climbable to make it execute on laps equal to or
greater than, or check Block Enemies to make it execute on laps equal to
or less than.
- By default, the executor will check current lap with the person in
last's lap. Check E4 to instead find the current lap from the player who
triggered it. This flag is better for triggering events ahead of the
players, while the default effect is better for triggering events behind
the players.
I don't fully understand this, but it's what software does and it fixes the issue of the lighting in DSZ3. Also don't need the extra call to R_Prep3DFloors.
There's no way atm to make you flash on your screen but not on everyone else's, so I think just making you invisible on all of them keeps the original SMK intent of "you have to pay extra close attention to their screen to know where they are at all" better
- Fixed a simple oversight that prevented P3 and P4's sounds from ever
playing
- Changed how sound priority works, now compares distances between
(Untested as of commit since my computer wants a quick restart before it
compiles :V)
I don't think it does anything for us anymore, and might even break things with slopes.
Someone let me know if I'm wrong and am breaking things horribly here.
Transformation based on screen space would make sense if we didn't want anything in the world to effect the sprites.
This should allow sprite splitting and sorting of sprites with level geometry easier.
stransform is no longer needed.
Solid walls *can* be cut
Fix issues with water and fog FOFs not cutting each other out correctly
Fix Fog colourmap and lighting setting that is done here.
Remove HWR_SplitFog
There is currently a bug with FF_DOUBLESHADOW (that also exists in software) but has a larger impact here. When 2 FF_DOUBLESHADOW lights are directly stacked on each other the bottom one has its height set incorrectly. This causes all the Fog in the timed gravity flipping section of ERZ2 to be drawn and it looks really bad.
This reverts commit 121fcd8369.
The reason I am reverting this is because the last commit actually fixes the *old* screenshot functionality, as the screen is being drawn back onto the buffer after they're swapped in the "real" size. Meaning the old function actually works perfectly fine now.
They still aren't perfect, but now they are at least not quite so obviously just translucent polygons over the level. A mixture between partially modulating the background colours and adding the fog colour. Notably white fog blocks look like they're brightening what's behind them.
Additive was also setting noalphatest before, can probably decide that depending on what it needs anyway. I don't think it's currently used anyway.
Use reactiontime instead of health so chain reactions can occur when multiple bombs are layered.
Make the check for nearby players happen BEFORE the spawning of explosion objects.
Remove MF_NOCLIPTHING and MF_MISSILE from bombs so they don't try and die when they hit the floor sometimes.
Removed Magnet item box pulling code. It's a mess, hacky, doesn't really help in races, and breaks things. We will implement something new for it soon.
Sorts all translucent sprites and MD2s so they're drawn after all the opaque ones. Fixes most of the observable issues between translucent MD2s and opaque sprites/MD2s.
