Additionally, place some optimisations in both software and OpenGL; in particular one has been added for when all of back and front sector (floor and ceiling) is sky: since everything is "open" anyway, we can simply the usual checks involved.
Thankfully it was really just a copy+paste of the code I already tinkered with for the normal ceiling sky based thok barriers, but tweaked for floors instead
(I suspect polyobject planes don't actually need the minx/maxx hacks anymore, but I haven't the time to test that tonight nor is this branch really suited for it anyway)
* Thok barriers with slopes now render fine in software
* The solid "sky walls" between different-height thok barriers adjacent to each other are gone. Forever.
This potentially allows FOFs and polyobjects to display sky flats on them properly, unless skyboxes are involved in which case they'd fail either way
I also updated or added comments to some places of the sky drawing code and related where useful
* Completely redid how splitscreen works, with eventual support for quads. Squish per-player stuff automatically into the right places! Works in GL, associated flag kills V_SPLITSCREEN.
* Seriously update the lives-drawing function for all gametypes, with strings that replace the lives number whenever it's missing (deprecates SKINNAMEPADDING).
* Improved how the nosshack works, alongside many other refactorings.
* ArchiveTables: print an error if invalid key, to alert script author potentially
* UnArchiveTables: if the key is found to be nil after reading key and value, print an error and don't set them in the table
This prevents a mobj of NUMMOBJTYPES from being created and potentially crashing the game. Really, this happens only if you start messing with the mapthings of respawning items like rings/weapons/etc in the first place via Lua.
* Lives position now more consistent between players in splitscreen.
* Ringslinger weapon bar is now at the same height as the lives pic, and also more centered horizontally.
* Begin tweaking emerald icon locations for ringslinger gametypes.
* Remove in-game team names from team gametypes, since this information is (mostly) conveyed by the lives pic.
Additionally, rename any remaining "srb2.srb" to "srb2.pk3" in the main source code files. Not sure whether to bother dealing with srb2.srb/srb2.wad mentions in project files for now.
* Change the horizontal spacing of the emeralds on the special stage tally screen.
* (unrelated) Fix a reference to srb2.srb instead of the now-correct srb2.pk3.
this also means we can remove a few ancient hacks relating to using the same code used to load SOC/Lua in WADs for loading standalone Lua/SOC files, though I haven't fully done this yet
* Make the NiGHTS link text pulse, like in the original game!
* Fix going from NiGHTS special stage as Smiles to a normal level losing your followitem.
* Update all the other V_DrawCroppedPatch calls to match the new behaviour.
* Fix the OGL version of V_DrawCroppedPatch to match the new behaviour.
(To justify my changes: It's not exposed to Lua, and the function signature was a mess. This way it's easier to mentally map how it would work.)
Also removed the + 1 from newtime, since there was never really any need for it. It just offset the interpolation so it went like (1 -> 2] instead of [1 -> 2), so you never saw the base appearance for each frame except at the end of any frames interpolating to it
Changed DrawMD2Ex's duration/tics type to INT32 so -1 comparisons work, probably want to change the signs elsewhere too but this is fine for now
"movebob" lets you determine the strength of movement bobbing (does not
affect landing delta, that's technically not movement bobbing :p),
values range from 0.0 to 4.0. viewheight is now relative to
player->height.
* Rename GZT_SPRITE to GZT_FRAME, since otherwise it's easy to confuse with EZT_SPRITE (which does something completely different).
* Fix issue where ghosts were facing wrong direction on spawn.
* Other minor refactorings.
* ...also, made smiles' tails pop up instead of down when skidding
* Fix replays for the current state of internal, irrespective of that previous thing.
* Fix replay ghosts for everything.
* Known issues; NiGHTS still prints an error message about desyncing on map start, but plays back fine. Curious.
* Add a default behaviour to followmobj (just basic A_CapeChase).
* Allow for modifying which character starting a new SP game should start you on, relative to the first valid character. (SOC's "startchar" variable)
* Make MF2_SHADOW transferrable via linkdraw.
* Modify P_GetSkinSprite2's recursion limiter to have zero chance of ever infinitely looping.
ATI_RAGE_PRO_COMPATIBILITY isn't used, and was disabled in r_minigl.c (the only other file that mentioned it) anyway. So let's get rid of support for it!
* cv_useranalog is now hidden from the menu.
* Directionchar now attempts to face the camera direction when you're standing still, and handles a few other states with more decorum.
* Tailsbot is now slightly more capable of keeping up with Sonic.
* pflags rearranged/adjusted, combining a few non-simulstaneous ones and turning PF_NIGHTSFALL into CR_NIGHTSFALL.
* [unrelated to branch] all ground-impact based abilities now happen more consistently with quicksand.
Makes it easier to change player state with Lua. Wasn't sure how to
tackle changing this for S_PLAY_CLIMB or S_PLAY_CLING, so I left them;
it's a minor ability-specific case anyway
Draw Textures and Flats that have holes in them like a solid polygon so they use the depth buffer and don't need to be sorted
Disable all linear filtering on textures and flats that have holes in them, the linear filtering introduces translucency into the textures where the edges are. Leaving them with either a black border, or causing pixels behind the slightly translucent areas to not be drawn. Doesn't apply to sprites and the HUD as they are always already sorted properly.
Make the Alpha Testing more strict on non-translucent blend modes. This makes it so any transparency below 0.5 is discarded instead. Would make anything that is blended and has holes in it look slightly better, only the HUD and MD2s where the texture has holes are effected currently.
Set TF_TRANSPARENT on flat texture flags when there are holes in the texture.
Minor fix to make sure MD2s always set the right blend mode
- Name each frame either SPR2_**** or SUPER**** (where **** is the 4-character name)
- If the name is 3 characters, '.' is accepted as a substitute for the '_', but a space/absent isn't (for tool-related reasons).
- Adds a big sprite2 index array to all models, even non-player ones. Sorry!
* Made MD2 frame interpoleration only work across the same spriteset (and sprite2set).
* Made MD2 frame interpoleration happen when there's less than a quarter of a second between frames, as opposed to the hardcoded specific animation disabling.
* Fixed sprite2-related typo in dehacked.c.
* Optimisations in a bunch of places, including to static
* Fix some visual errors with text and patches near the edges of the screen in non-standard resolutions.
* Changed the save format a little more, since I had free reign over it.
* Modified the string drawing functions to not awkwardly clip at the very edges of the screen, considering the relevant patch drawing functions avoid out-of-range memory writes.
* Fix a bug where I got emeralds and mapnumbers mixed up when checking for the "there's a tailsbot" flag.
* Consider a save with an invalid skin an invalid save, rather than allowing its continued presence.
* Each time you die, the number of game overs you've had is counted.
* Your save file updates to record this.
* The number of startinglives is determined by the number of times you'ved game-overed, with the maximum being infinity lives (thereby providing a cap on the number of game overs you can go through in a typical game).
Requires a new patch.dta, but I'm not uploading that yet because not happy with the icon we've got going for infinity lives on the save select menu.
Lua lump load only
This branch prevents the following Lua functions from being used within hooks or coroutines, to prevent netgame desync problems or any other similar oddities when using these weirdly:
* `freeslot()`
* `addHook()`
* `hud.add()`
* `COM_AddCommand()`
* `CV_RegisterVar()`
All of the above should only be called when the Lua script is being loaded (i.e. it takes place the same instant a ".lua" file or a WAD file with a "LUA_" lump is being loaded)
To put it another way:
```
//This is valid usage:
freeslot("MT_TEST")
//This is NOT valid usage
addHook("MobjSpawn", function() freeslot("MT_TEST2") end, MT_PLAYER)
```
See *Monster Iestyn/Lua lump load only* on the FTP for an exe and test script.

Add-ons menu
Does what it says on the tin! Very pretty. Would like help testing in filesystems that are not Windows, although I've recieved assurances from Sryder that since it's based on the same filesrch code, it should work cross-platform. Just want to confirm it works, though.
Also, M_* is whitelisted lumpname too.
root/!LatestSRB2Files/srb2win_branch_addfile.exe, requires new patch.dta.
See merge request !92
Consistent flat alignment
Does what it says on the tin. Consistent between the three different plane drawers:
* Software flat (previously the only one working as intended)
* Software sloped (took a lot of work)
* OpenGL flat and sloped (worked reasonably well but used different signs for some reason)
Check out root/!LatestSRB2Files/srb2win_branch_flat2.exe, root/toaster/flatalignment.wad and any in-dev DSZ1 to test it all out.

NiGHTS Paraloop-special emblems
Implemented the two NiGHTS Emblem types in the TUDD via var modifications to ET_GLOBAL!
* GE_NIGHTSPULL (for it to chase you once paralooped) - Sun emblem
* GE_NIGHTSITEM (for hidden until paralooped) - Moon emblem
* Combined means that you essentially have to loop it twice.
Also, revamped NIGHTSITEM to suck a little less (and have more compatibility with MT_EMBLEM).
Check out root/!LatestSRB2Files/srb2win_branch_nightsemblems.exe with the latest patch.dta, along with root/toaster/nightstest.soc for a sample in GFZS.

MF2_LINKDRAW reliability improvements
Seriously improves the reliability of the linkdraw system (in Software, the only rendering engine which actually does anything with this information), reducing the number of visual errors it produces significantly. Deliberately engineered to only affect objects with MF2_LINKDRAW applied.
Of particular note: Standing in shallow pools of water as Smiles will now reliably associate the bottom half of the tails following mobj with the underwater portion of Smiles' body, and the flicking ends with his un-submerged head.
Test with ```<root>/!LatestSRB2Files/srb2win_branch_linkdraw.exe``` and ```<root>/toaster/smiles.wad```.

Wallspike tweaks
Sorry, MI. You told me to test the objects via objectplace, and they worked fine there - but @FuriousFox had some [issues](http://i.imgur.com/DQuLYzz.png) when he finally got to place them via mapthing.
Specifically, I think the problem this was caused by was a straight up copypaste of the "height" attribute of MT_SPIKE into the "radius" field of MT_WALLSPIKE, when it should technically be half that to match the intended collision box. Some other stuff also got adjusted to match when I solved this.
FF's happy now - they work well enough to place, even if their [collision is a little wonky](http://i.imgur.com/o2rG0tV.gifv), but that's an MF_PAPERCOLLISION issue and more than a quick fix to be done in an evening.
Nab ```<root>/!LatestSRB2Files/srb2win_branch_spikefix.exe``` to test.
UPDATE:
* Support for MF_PAPERCOLLISION tmhitthing in P_SlideMove.
* Knockback for wallspikes is much more consistent, fixing FF's gif as posted above/below.
* Optimised away a FixedDiv call when determining the slopetype of a line.
* Changed the position of the wallspike base slightly.
* Made it so NOTHING can step up onto the player outside of other players, essentially killing a bunch of springs-launch-with-players style bugs. (I was able to recreate that issue with the wallspikes until I added this, which is why I did it in this branch.)
* Wallspikes are now bustable.
* Invert the solidity mapthing flag for spikes and wallspikes.
* Improve the frame arrangement for vertical spikes' spriteset. (Requires new patch.dta)
* Make all spikes consistently do damage with DMG_SPIKE.
* (unrelated) renamed "flame stomp" to "elemental stomp" in P_HitDeathMessages.
* (unrelated) Make gas jets not make noise if they have the ambush flag, per Sphere's request.
See merge request !107
This allows saving in special cases where you can go to a map that
doesn't save, and then back to the map you saved on (see: SUBARASHII
special stages), while still preventing you from killing your lives by
repeatedly retrying in said map.
Kept lastmapsaved just in case. Can be removed if deemed unnecessary.
* Fix an issue where everyone being game overed except for one person, and then kicking that one person, meant the game over trigger was never met.
* Fix an issue where the spectator text could be overridden with a count of the number of remaining players to complete the level.
* Fixed a few glitches with spinning. (Unrelated to the branch, but exposed through new_coop testing.)
* If NONET, the Multiplayer option on the main menu leads directly to the Splitscreen menu, which also includes player 1/2 setup under this circumstance.
* A mechanism to save player name, skin and colour as defaults to config.cfg.
* Improve the code for busting vertical spikes.
* Improve the frame arrangement for vertical spikes' spriteset. (Requires new patch.dta)
* Make all spikes consistently do damage with DMG_SPIKE.
* (unrelated) renamed "flame stomp" to "elemental stomp" in P_HitDeathMessages
* Support for MF_PAPERCOLLISION tmhitthing in P_SlideMove.
* Knockback for wallspikes is much more consistent.
* Optimised away a FixedDiv call when determining the slopetype of a line.
* Changed the position of the wallspike base slightly.
* Made it so NOTHING can step up onto the player outside of other players, essentially killing a bunch of springs-launch-with-players style bugs. (I was able to recreate that issue with the wallspikes until I added this, which is why I did it in this branch.)
Or rather, I killed anything to do with the old background orb, renamed all "EMMY" stuff to "TOKEN", and of course adjusted the new S_TOKEN accordingly
You can either add FF_SPR2SUPER directly to the sprite2 arg if it's a number, or you can use the new (optional) boolean arg between sprite2 and frame, where as you'd expect false = normal and true = super.
* Crash prevention if total somehow becomes zero.
* Don't waste time multiplying and demultiplying the HUD check if it's just gonna net you the same number.
Pwease no kicky
Don't kick Tails! Also, a movement for the WRITESINT8 to prevent modification to buf if the function bails early.
This can go into Master, right? It only matters for the host, and it's explicitly only having a major effect outside of netgames.
See merge request !201
*Add CONS_Printf messages for !netgame checks
*Arg count is checked first regardless of netgame status for both kick and ban, < 2 is checked instead of == 1 just in case these weren't called from console for some stupid reason?
*Moved Command_Kick's buffer vars to within the code that actually does kicking stuff
* Hide the individual lives on the tab menu whenever they're irrelevant.
* Make co-op spectators appear on the tab menu.
* Hide one frame of spectatorhood stuff in splitscreen.
* Fix joining netgames whilst in a special stage not giving the startinglives.
* Make monitors that don't appear to do anything play the failure sound.
* Only make players flash if they're REspawning, rather than spawning into a fresh level - unless it's a NiGHTS level, in which case never.
* Make the default value of cv_playersforexit "All".
* Correct the greying out of the lives counter for cv_cooplives == "Single pool" to only be when you can't respawn.
NEW COOP BASED:
* Add "Infinite" option to cv_cooplives, inspired by SUBARASHII. Lives still exist, but are hidden from the player's view, and are prevented from falling below 1 at any cost. As a result, made the variable CV_CHEAT.
OTHER MULTIPLAYER BASED (semi-related):
* Made cv_autobalance an on/off switch which determines the allowed difference based on the number of people in the server, instead of a weird and opaque number from 0-4.
MENU BASED (not related):
* Add horizontal arrows to menu options which respond to the arrow keys.
* Make the menu arrows bob.
* Switch out the seperate arrows for combination arrows on the joystick menus.
* Minor cvar description tweaks.
* Don't attempt to respawn anybody when changing cv_coopstarposts and nobody CAN be respawned.
* Make Rings transparent (and not flash) when you're a spectator.
Lua archive value fix
This fixes some potential problems with archiving mobjinfo_t/state_t data via Lua in netgames (whether as custom mobj/player vars or by NetVars hook). Thanks to LJSonic for pointing this out to me.
See merge request !200
Apart from the fact that UnArchiveValue reads UINT16 for both anyway (which alone causes problems), but UINT8 isn't even enough to store the higher end of the object types list and definitely most of the states welp
The issue was that because both them and the player had MF_SOLID, the tmfloorz of the spring was getting set to above the player (or vicea versa with tmceilingz), forcing it upwards with them under certain circumstances.
Now, springs only acknowledge the solidity (for purpose of tmfloorz/tmceilingz) of objects they CAN'T launch.
****
* MF2_MACEROTATE. Apply to any object. Replaces the indiscriminate spamming of A_MaceRotate each tic.
****
* Mace point mapthings have been slightly modified.
- MTF_AMBUSH: bigger luke theory (has no effect on custom mace, different effect on spring mace)
- MTF_OBJECTFLIP: flips the objects, but nothing else - just so it doesn't look out of place in gravflip sections
- MTF_OBJECTSPECIAL: keeps it from attempting to play swinging sounds
- angle: tag of controlling linedef
- parameter: number of "spokes" minus one - for example, a parameter of 2 results in 3 equidistant maces rotating around the same point.
****
* Mace linedefs have been significantly revamped.
- line dx: number of chain links
- line dy: speed (in FU)
- frontside floor height: Pitch (in degrees; how much it "tilts" over - Yaw influences the axis it's tilting on)
- frontside ceiling height: Yaw (in degrees; rotation of entire thing on xy plane)
- frontside x offset: Phase (in degrees; how far it is through the rotation cycle)
- frontside y offset: Max speed (in FU; if less than speed, set to speed*2)
- backside floor height: Pinch (in degrees; 0 if no backside; essentially makes rotation conical instead of wheel-like)
- backside ceiling height: Roll (in degrees; 0 if no backside; rotates on the axis of the spinning - identical to Phase for spinning maces, but useful for rotating swinging maces as opposed to just offsetting them)
- backside x offset: Number of "antispokes" (0 if no backside; makes that many spokes not exist so you can put another mace/chain type in there instead; for combo mace/chain instead turns them into chains directly)
- backside y offset: Width (in number of extra chains per side; 0 if no backside; creates a "skiprope" arrangement)
----
- ML_NOCLIMB: for chains and chain-mace combos, allow for player control of yaw through strafe keys
- ML_EFFECT1: replacing the seperate mapthings, this makes a mace type swing instead of spin.
- ML_EFFECT2: for all spokes of the mace wheel ending in maces, make the chains out of the mace type (inverted for firebars)
- ML_EFFECT3: spawn a bonus mace type at the center(s) of rotation
- ML_EFFECT4: don't clip inside ground
****
* Mapthing 1104 represents both spinning and swinging maces from prior versions of SRB2.
* Mapthing 1105 has gone from being a swinging mace variant to a combination of chains and maces in a single unit, provided the number of "spokes" is greater than one.
* Mapthing 1105 has gone from being a swinging chain variant to a vertical spring-on-a-ball-on-a-chain. Yellow by default, apply MTF_AMBUSH to turn into a red spring.
* Mapthing 1107 represents both spinning and swinging chains from prior versions of SRB2.
* Mapthing 1108 is completely untouched except to port over 2.1's functionality to the new backend.
* Mapthing 1109 is a Mario castle-level style firebar. This inverts the functionality of ML_EFFECT2 on the tagged linedef.
* Mapthing 1110 is a free slot should we want to implement another type of base-game mace.
* Mapthing 1111 is a custom mace. Use the linedef's frontside texture slots to identify a macetype mobjtype, then use the backside texture slots to identify a linktype mobjtype (defaults to MT_NULL if no backside).
****
Whooh. Requires new patch.dta for sprites.
OpenGL papersprites
I don't know if anyone actually tested Sryder's original OpenGL papersprites support before it was merged in, but there was some issues with the papersprites themselves "wobbling" about in a sort of weird way depending on the angle you view it from or where you are. It's easiest to see what I mean if you just load up sawb.wad, and strafe about when viewing one of the sawblades.
Thankfully all I really needed to do was tweak the way angles work for papersprites. I also cleaned up Sryder's original code a little, not that I really needed to do so though.
See merge request !96
"MapThingSpawn" hook for Lua
A hook for adding special stuff to mobjs spawned via a map thing on level load, like special features depending on the map thing's flags, angle, z position, extrainfo, or anything else I didn't think of.
**Function syntax:**
`functionname(mobj, mapthing)`
where `mobj` is the spawned mobj (type mobj_t obviously), and `mapthing` is its corresponding map thing (type mapthing_t also obviously). Note that `mapthing.mobj` will not yet be set to `mobj` at this point (it's set afterwards, provided you don't remove the mobj or something stupid).
Returning `true` overrides features in place for existing mobj types (currently not all existing features are overridden, I may change this; see the source code for what IS overridable for now), returning `false` runs them as normal.
**Hook syntax:**
`addHook("MapThingSpawn", functionname, MT_OBJECTTYPE)`
where `MT_OBJECTTYPE` is the object type to apply the hooked function for. As usual, if this argument is omitted or set to MT_NULL, the function runs for all object types.
**Test resources and where to find them:**
* srb2win-mapthingspawn.exe, my folder on the FTP - test exe, obviously
* luatest-mapthingspawn.lua, same place - a simple Lua script that changes the scale of MT_GFZFLOWER1 (the orange flower) based on the map thing's angle (0 degrees is normal, 90 degrees is 2x bigger, 180 is 3x bigger, 270 is 4x, etc etc)
See merge request !83
MI code cleanup once again
Code prettification branch 12472849127, no real changes to gameplay except a bunch of outdated SOC features have been removed or disabled (most notably, Callum's old texture/patch SOC implementation). Though the changes here might also speed up game startup a teensy bit I suspect, possibly?
See merge request !102
* Make swinging (as opposed to spinning) maces play the activesound at the peak of their speed.
* Decouple the tilt of all maces from the angle.
* Improve DBG_GAMELOGIC message.
* Refactor.
* Refactor of the unbundling to not involve modifying the next/prev links.
* Make the booleans in vissprite_t use flags stored in sprite->cut instead.
* Make the linkdrawn sprites much more linked - ie, same brightness (unless independently fullbright), same colormap, and don't draw if the tracer isn't being drawn.
* Other minor corrections.
I also optimised those two functions while I was there (why keep a "floating" variable when setting it to false guarantees the functions return false?)
Of particular note: Standing in shallow pools of water as Smiles will now reliably associate the bottom half of the tails following mobj with the underwater portion of Smiles' body, and the flicking ends with his un-submerged head.
Deliberately engineered to only affect objects with MF2_LINKDRAW applied.
-Colormaps, palettes and other stuff are properly loaded now. It was a bug related to the generation of the lump name with files in the root of the PK3.
Known issues:
-Map WADs' REJECT and BLOCKMAP are still not loaded.
*removed Texture/Patch SOC implementations, since they weren't used in the end
*removed remnants of AnimTex and some Spritename thing
*none of the save* arrays in DEH_LoadDehackedFile were being used, so I removed all related code disabled or otherwise
*DEH_LoadDehackedFile doesn't need a "wad" param anymore since only the Patch block was using it
"pmData" was originally declared in the files in the (non-SDL) OS2 source subfolder, last known to be present in Demo 4.1's source code ...said folder has not been around for over a decade, so this would definitely fail to compile if you tried compiling for OS2 without SDL anyway
OpenGL slope FOF lighting fix
This fixes some issues with sloped FOFs that affect lighting in OpenGL (as in, those that cast a shadow or have a colormap). Particularly, they can do strange things to any wall textures adjacent to them, as we've noticed ourselves in levels for 2.2. =P
See merge request !194
Fixes with respect to sector special touching and slopes
Some important stuff.
* SF_TRIGGERSPECIAL_TOUCH now actually works. Previously, it abandoned the loop early if ANY bounding sector didn't have that sector flag, which it likely didn't - only checking one extra sector's worth of FOFs. Also, the teleport handling there is more robust, and actually bails out if you teleport, instead of just awkwardly continuing through the loop.
* SF_TRIGGERSPECIAL_TOUCH now works for each time thinkers, too.
* Fixed a bug with being able to go under lava because P_CheckSolidLava doesn't take slopes into account.
* Also, P_CanRunOnWater supports slopes now too.
* Quicksand supports slopes and reverse gravity now.
* Space Countdown supports slopes now.
Also, an experiment behind a #define which currently isn't turned on:
* UNDER A #define, "SECTORSPECIALSAFTERTHINK", WHICH IS CURRENTLY TURNED OFF, BUT I WILL WANT TO TURN ON IN INTERNAL: Moved sector touch handling to P_PlayerAfterThinker (from P_PlayerThinker before movement). Allows for being able to trigger moving slope sectors that are going down, most specifically lava (didn't matter in RVZS in 2.1 because you could clip through the sides and go underneath the lava, causing damage - a sloped testwad version of that prevented going underneath.) Also fixes one-frame standing on deathpits before you die. Basically means sector triggers effectively happen one tic earlier, since it's after movement.
See merge request !131
Polyobject seg render fix
This fixes both Software and OpenGL renderers so that polyobject segs aren't drawn if the game is drawing the actual subsectors they're from (outside the main level, where the polyobject walls were pre-spawn). They should only appear as part of the polyobject itself in-level.
This means a few glitches with polyobjects are probably fixed: for instance in Software mode, polyobject walls sometimes appear through level boundaries (and make everything above/below vanish, turning into HOM or skybox), if the BSP rendering code happens to find one of the subsectors said segs came from outside the level. I don't think anything similar happens in OpenGL, though I'm sure some unwanted typecasting is happening as a result of attempting to draw the segs. (And it fixes a crash in 2.2 anyway.)
See merge request !195
Ping-related code fix
Somehow, the part of the netcode for calculating the players' pings in a netgame frequently gets the concepts of nodes and players mixed up, which is probably not a good thing. This branch of course fixes those slipups.
I originally based this branch on master to be merged to it (since it only fixed issues on the host's side), but after finding another issue with clients receiving PT_PING from the server, I decided to make this a merge to next instead.
See merge request !193
Ld414 invalid sound fix
This fixes Linedef type 414 crashing the game if an invalid sound number was supplied to it (this can happen if you, say, scrambled THZ2's textures *cough*), whether or not the "Repeat Midtexture" flag is checked.
See merge request !196
