Object tracking is off, but it was off before so I don't know if I actually
broke it. Minor refactoring in HWR_RenderPlayerView and HWR_RenderSkyboxView.
* Fixed a bug where you'd see :nick: on the current character selection screen if you didn't have many skins loaded.
* Fixed a bug where character skins loaded in PK3s would attempt to load every single lump of the PK3, even if it wasn't in the same subfolder as the original S_SKIN, as a sprite into the player struct. Could stand to be ported to vanilla.
Requires new chars.kart, which was created using the help of the indev 2.2-based Kartmaker update which will be available shortly.
Previously sounds with an origin would always start at max volume. This is
because the distance calculation adjusts the volume, and that volume needs to
be updated every tic as distance changes. Storing the original volume works.
(cherry picked from commit 4ce347c6f2)
* Fix the title card fade's one-frame invalid memory read.
* Disable a redundant gamestate-activated wipe, which A) horribly broke Encore wipes, B) made normal map transitions take longer than they should, and C) held on the one glitchy title card wipe frame to make the game look more broken than it was.
* Fix Encore wipes being broken by the merge.
* Disable (not remove; may want to use later) the :nick: patch draw attempts from the title card drawer.
* Re-add zonettl support to the title card drawer.
* Move the title card drawer in front of the fade (Looks better for if we showcase 2.2 merge footage before creating a better title card).
Line specials 777 - slope floor by anchors, 778 - slope ceiling by anchors,
779 - slope floor and ceiling by anchors.
Thing types 777 - floor anchors, 778 - ceiling anchors.
Summary.
These line specials slope the front or back sector's floor/ceiling by 'anchor'
things. Anchors are floor or ceiling specific and snap to the nearest vertex.
Using this method it is possible to create seamless slopes, without even
tagging.
Details.
Normal slope flags apply. To slope the backside sector, set No Climb on the
line. An anchor each is required to be near three of a sector's vertices in
order to slope it. More may be present but the order is undefined.
MFE_SPRUNG flag not being applied to the object sprung would cause a infinite recursion of `P_TryMove` -> `P_CheckPosition` -> `PIT_CheckThing` -> `P_DoSpring` -> etc
Also fix springs not being de-solidfied
Dunno what's up with the spring sound not playing
