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
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.
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
Polyobject segs should ONLY be drawn if the polyobject itself is in the polylist of a subsector being rendered. That way you won't sometimes see polyobject walls through level boundaries, if you happen to be close enough to their pre-spawn locations outside the level (or in them, if you decided to go on a noclip journey).
Ignore askinfoviams
Turns out PT_ASKINFOVIAMS is an obsolete packet type anyway, the MS doesn't send it at all. So let's just ignore it in the netcode then. (the online page just acts like a client and sends PT_ASKINFO, and is not part of the MS itself)
See merge request !191
Netcode hotfix
Various netcode fixes are included in this branch. Most important of all of course is a fix for the Net_CloseConnection invalid node -32769 detected message thing, or rather what actually caused that to occur.
It's a merge to master since everything here should be compatible with 2.1.18: the only main changes are related to recieving packets (whether you're the host of a netgame or a client), which AFAIK shouldn't cause desyncs if you played with these fixes on a 2.1.18-hosted netgame (or hosted a netgame with the fixes and 2.1.18-using players join you).
See merge request !185
A bunch of bugfixes about too many wads in netgames
Fixes:
* Having bunch of music WADs added and then breaching the file limit(s) through joining a server with important files added. http://mb.srb2.org/showthread.php?t=42662
* Having a bunch of music WADs added, joining a server, and then breaching the file limit(s) when the server adds a file. https://mb.srb2.org/showthread.php?t=34664
* Informing the adminplayer whenever they try to send a request addfile net command but the file limit(s) are reached.
Done into next because I might as well be 100% safe, even though this could probably work on master as well.
See merge request !187
Missiles 'n slopes
Fixed that thing where missiles like sliding up slopes for some reason.
This isn't a 1:1 fix compared to non-slopes - missiles still like stepping up over the borders of sloped sectors and will continue going as long as they never touch that ground again, whereas they can never step up on flat ones - but this fixes the most egregrious issue.
See merge request !181
* if you sent it to a client rather than the server, game over, your connection is closed
* if files that don't exist or are too large are requested are listed, game over, your connection is closed (they should have been checked on YOUR side beforehand, silly)
* if the server has downloading disabled anyway, ...yeah, you get the idea
Don't worry, I made sure Got_RequestFilePak cleaned up the full file request list for the node in case of failure
This is just in case someone actually tries to dump in C_START/C_END and "add" colormaps using them, not that they would ever be used currently anyway.
Admin ban fix
Okay, THIS time admin bans should work properly. Turns out the relevant code for banning did not properly consider the case of admins doing the banning, at least until now.
Unlike my last attempt at fixing admin bans (!165), this one would require both host and admin to have the fix exe assuming everyone else would be using 2.1.17, so I'm merging to next instead of master.
See merge request !167
Allowteamchange fix
Fixes "allowteamchange no" to actually work properly and NOT desync you from the game in most cases. You can now switch TO spectator freely (as intended it turns out), and switching FROM spectator is prohibited. The "Enter Game" menu option in Match/Tag now displays one of those blue window notices just like with "Change Teams" in CTF/Team Match if you cannot change teams right now. Everything else works as you'd expect.
The de-sync issue was originally reported here https://mb.srb2.org/showthread.php?p=789965#85
See merge request !168
Falling rocks fix
This fixes the rock spawners' rocks not being removed if they rolled down to the ground from a slope rather than bouncing (see https://mb.srb2.org/showthread.php?t=41963)
See merge request !162
doesn't draw off of the sides, and doesn't ignore snapping or widths for reasons that don't make sense
(for instance: the green bar in MI's test script showed *above* the blue one in non-green resolutions in 2.1.17)
Command-line skin selecting fix
Fixed http://mb.srb2.org/showthread.php?t=42312.
Also, fixed being able to change your skin colour during credits/cutscenes in singleplayer.
See merge request !158
(various large invisible blocks used in the level cause rain to make splashes high above the main level, high enough to make ghostly rain splash sprite artifacts appear sometimes in nearby areas)
This is used by Command_Addfile in the MD5 calculation code, so that it can search subfolders properly and allow addfile in netgames to treat them the same way as in SP
This fixes the grid floors in TD's Lava Mountain freezing the game if they go off the bottom of the screen far enough (they have ACWRFL1A as the wall texture, which is a single patch texture with holes)
* Fixing an inconsistency with being able to change skin colours when you shouldn't be able to, much like the previous skin change issue that was fixed.
-If the server tries to kick a joiner who is downloading the game state, they will get a timeout instead, because a regular kick would only happen once the game state has been downloaded
-Added a timeout for player ticcmd packets, again to prevent freezes to happen in some cases
-File/game state downloading is now faster, the speed is controlled by the "downloadspeed" cvar, in packets per tic
-The reason is now properly shown when the server refuses connection
-Changed the default values of "nettimeout" to 10 seconds (previously 15) and "maxsend" to 4 MB (previously 1)
-Added a "noticedownload" cvar that displays a message in the server console when someone is downloading a file
CMake: Fix nasm Linux builds
When compiling under Linux with CMake and nasm/yasm enabled, the operation would fail during linking with undefined symbols related to the tmap files.
This commit adds support for passing flags to the assembler and passes ```-DLINUX``` in order to compile.
After this change, binaries are successfully compiled with either nasm or yasm on Linux systems.
Tested on Ubuntu.
See merge request !153
Savegame hotfixes
Yes, this another netgame related fix! Named this "savegame hotfixes" rather than "ERCZ hotfix" or the like in advance of the fact we probably need a general branch for other $$$.sav fixes?
Anyway, fixes included in by this branch:
* ERCZ's lava falls now act as expected rather than being stuck in place for the map's duration, fixing all other known desynchronisation issues known in the map for the time being (yay)
* Changing sector tags in a map no longer causes joiners to netgames to have their SRB2 application stop responding etc
* Player names should no longer turn red in the console in gametypes outside of CTF/Team Match if a resynch occurs (not $$$.sav related, but it's related to netplay so I lumped it in anyway)
See merge request !150
One Eggscalibur fix
Use mobj->watertop instead of mobj->spawnpoint->z. CEZ3 is far from fixed in multiplayer, but this is still one less thing to worry about.
See merge request !148
Software plane rendering fixes/cleanup
This is mostly cleanup, with the exception that polyobject planes should now behave somewhat better than they do in 2.1 currently (translucent polyobj planes should now always be actually translucent regardless of where you view them from, for instance). I can't claim I've fixed their rendering once and for all though, there may still be bugs for all I know...
See merge request !136
Some texture-related fixes
Bugs fixed in this branch:
* upper/lower/middle textures with non-existent texture ids being capable of crashing the game. For instance, RVZ1 has colormap codes on non-colormap linedefs, which causes them to wind up with invalid texture ids because of how the game tries to interpret lower/upper textures with "#" followed by characters on normal linedefs. Fortunately these "textures" are normally not visible anyway (since they're all in control sectors) unless they are swapped with in-level textures by some crazy Lua script of some sort...
* animated single-patch textures with holes displaying garbage on first viewing (see this thread: https://mb.srb2.org/showthread.php?t=42195)
* the heights of the lighting (shadows or colormapping) from water/translucent/shadowcasting/etc FOFs become messed up when displayed on repeated midtextures.
See merge request !144
Flat changing hotfix
This should fix how Lua scripts that change flats in levels, particularly to flats that don't already exist in the level, cause SRB2 to crash for anyone who joins a netgame afterwards. (I'm not sure if it's a consistent thing or not though)
Probably needs a good test to verify the issue is completely fixed before being merged in. Maybe there are other minor things I didn't account for in this fix? I don't know!
See merge request !141
Dunno who thought it was a good idea to lump tag, nexttag and firsttag together in $$$.sav, but that meant changing sector tags caused SRB2 to stop responding since it lead to the tag lists being broken
This fixes ERCZ's lava falls not moving after joining a netgame at that stage. Possibly explains other various floor/ceiling related netgame quirks that haven't been noticed until now, maybe even in multiplayer levels.
Remove secplanes
This is just removing SSNTails's old port of ZDoom's secplane code and math, from back when he attempted slopes himself. The slopes we've had since 2.1.15 however do not need these, so we can pretty much toss the code for them out now (nothing uses them anyway).
See merge request !149
-Updated packet name list so the debug file no longer shows garbage packet names
-Replaced byte values with actual net command names in the debug file. Only the first net command in a packet will be shown though
-Added a MOBJCONSISTANCY define that makes the game takes all revelant mobjs to be counted in the synch seed
-Added a PACKETDROP define that adds two console commands "drop" and "droprate" to simulate bad internet by dropping packets
-Added/changed comments here in there in the netcode
-Fixed a minor error that would ignore one of the urgent ack slots
-Added a space between the map name and "zone" for the messages shown in a joiner's console
This fixes Brak's electric barrier disappearing for joiners to ERZC. There seems to be some issues with the lava falls there too I've found, but the electric barrier actually stays around now at least
Smoother ropes and zoom tubes
Makes rope hangs and zoom tubes suck less. Specifically, they handle corners (and vertical height changes, ala sloped rope hangs) a LOT nicer. Ported from internal.
See merge request !139
As LJSonic has pointed out, there's no need for a for loop in either case; just use sector->floorpic/ceilingpic as a levelflats index directly
(Besides, if that was to stop any out-of-bounds indexes being used, that's hardly the way to do it anyway)
Turns out sdl12's version of this function only did stuff for DC/GP2X ports; support for them have been cut out for SDL2, so for now let's just not use the function at all
I'm convinced there's going to be some stupid side effects from doing this, but it's the quickest way I can fix the polyobj planes not all appearing anyway
Console improvements
* Unused console backgrounds no longer take up memory
* Input cursor can now move left and right
* Support for selections (Shift-arrow keys, CTRL-A, etc)
* Clipboard support (CTRL-C to copy, CTRL-V to paste, CTRL-X to cut)
* Fixed handling of simultaneous modifier key presses
https://dl.dropboxusercontent.com/u/3518218/21/console.gif
None of this affects chat yet, that's not part of the console. I'll look at it later.
See merge request !133
I added similar checks for the other num* but it seems some MD2s break the other limits without knowing anyway ...so I've commented these checks out for now, unless we have further discussion regarding them later on
* Space sector support complete, bounds of drowning now altered slightly.
* Knuckles climb now has symmetrical slope support for both normal and reverse gravity.
* All slope-determining topheight and bottomheight code is now identical in form.
* Camera postimages now support slopes properly.
Moved the handling of P_PlayerInSpecialSector to P_PlayerAfterThink from P_PlayerThink.
* This allows the player to get hurt on sloped lava surfaces that are moving downwards.
* Also prevents the player from standing on death pits for 1 tic.
* Prevents the player moving 1 extra tic's worth of movement of pain when hit by sector.
* Thankfully, no consequences re conveyors.
* Like, the only consequences I've found have been positive. However, this DOES need to be thoroughly investigated before it can be allowed anywhere near Next itself.
(neither does P_CanRunOnWater, but I don't think it's necessary to make that check more complicated as you probably shouldn't be able to waterrun up steep surfaces anyways)
Also, the "teleport" devmode command can now gracefully handle coordinates specified outside maps with no/few thok barriers, which previously prevented teleport via the thok barrier bleed's sector floor and ceiling being equal.
Fixing various problems with MF_SOLID collision
(I, toast, wrote the original merge request, but Alam made this merge request because I made a mistake. Twice. In a row.)
* Solid objects are now no longer intangible when your z is less than the other object's.
* I originally thought the bug was limited to just solid objects on slopes (hence the branch name), and was wondering about undesired side effects - but looking at this gfy, this was a major bug that slopes made easier to expose.
* Unfixed = http://gfycat.com/BareLimitedCavy
* Fixed = http://gfycat.com/JubilantOffensiveGar
* You now properly lose your momentum when jumping at a solid object.
* The way I fixed this was a hack, but it was originally a much worse hack which resulted in very bizzare physics issues, so...
* Unfixed = http://gfycat.com/ShockingAbsoluteArthropods (also demonstrates the first bug)

Fixed players disappearing when spindashing whilst wearing multi-layer shields
* Before: http://i.imgur.com/gxUFElo.png
* After: http://i.imgur.com/NxsOg94.png
The problem was that MT_OVERLAY's default radius and height were never getting changed from 1*FRACUNIT, and that meant that when you spindashed, the game considered it completely below the surface of the flat you were standing on. Since you're not usually clipped on flats that don't belong to FOFs, we didn't notice this aspect of the issue sooner.
(SORRY FOR THE MULTIPLE MR'S AGAIN I TOTALLY SUCK AT REMEMBERING TO MAKE SURE IT GOES TO NEXT INSTEAD OF MASTER)

v.drawScaled negative scales fix
Lua now errors if you try to use negative scales with v.drawScaled, rather than crashing as it does in 2.1.16 currently. Not much else to say here.
See merge request !126
Fixing FF_REVERSEPLATFORM clipping fixes
Forgot the case where == 0.
Tested by @wolfy852 in Top Down, where the bugs this caused were first discovered.
See merge request !121
Even more slope-related fixes
What it says on the tin pretty much:
Currently included fixes:
* Pusher specials applied to FOFs did not properly account for slopes applied to the bottom plane; this probably was just a minor slipup that appeared on adding the support in the first place, I take it? (some waterfall in the last section of SUGOI's Fudge Canyon is the only place I can think of offhand where this bug is noticable)
See merge request !114
Treating " as whitespace in TEXTURES (and animdefs too i guess)
SLADE adds this character in its TEXTURES editor and makes SRB2 cry unless the lump is manually edited; this just treats it as whitespace so we don't have to think too hard about it.
Also, two I_Errors now refer to the correct lump name.
See merge request !122
(the problem was that MT_OVERLAY's default radius and height were never getting changed from 1*FRACUNIT, and that meant that when you spindashed, the game considered it completely below the surface of the flat you were standing on. Since you're not usually clipped on flats that don't belong to FOFs, we didn't notice this issue sooner.)
Basically, it manually sets *_FOUND, *_INCLUDE_DIRS and *_LIBRARIES instead of using find_package. Frankly I have no idea how well what I've done works currently though, not even sure if I've set the _LIBRARIES variables correctly. Again, it's WIP work, this can probably be fixed eventually I suppose.
HOWEVER, since these changes to PIT_CheckThing do raise questions about whether there may be unintended side effects here. As a result, I may remake this for internal only if necessary.
More slope fixes (aka sorry guys I made another quick SUGOI fix)
Another slopes fix branch!
This branch currently includes a fix for:
* Knuckles gliding into a slope while in 2D mode causes him to try to "climb" on air above them, if the original non-sloped height is higher. Unfortunately he still tries to grab onto places that he can't really climb on, but at least now it's on the slope itself and not in mid-air lol. This issue is encountered in SUGOI's Retro Hill Zone, if you want to check for yourselves.
* Bustable FOF-busting code for both players AND pushables not accounting for slopes
* (Unrelated to slopes): Fix FF_SHATTERBOTTOM FOFs acting like THZ goop when stood on; I added this fix as a bonus because I encountered it in a test map of mine for the bustables fix
(Other fixes may or may not appear here in the near future, I haven't decided yet. Don't wait on me to get in any further fixes before merging, that said)
See merge request !110
Last-minute NiGHTS exiting bugfix
One single-line fix concerning the end of NiGHTS maps. Extremely small, literally zero side effects here, the only reason I'm not committing directly to master (aside from ettiquette) is that I don't have the ability to do so.
* The NiGHTS drone had a single tic of visibility when you hit the goal, which is evident stepping frame by frame through http://gfycat.com/ComplicatedComposedAoudad (the contents of which may or may not make it into 2.2). This is no longer the case.
See merge request !100
Cutscene switch fix
Yet another fix for SUGOI, lol: apparently going from a final level's post-cutscene straight to a custom credits cutscene gets the latter stuck forever in the first scene (because the game accidentally stops the cutscene responder from realising the custom credits cutscene is running). This branch of course makes a fix for that.
See merge request !108
Wall collision fixes
Fixes included in this branch:
* A fix for a specific crash encountered in a SUGOI map (sound familiar?) caused by bouncing off a wall adjacent to a slope
* A fix for solid midtextures not accounting for Effect 3/Peg Midtexture properly (https://mb.srb2.org/showthread.php?t=41462)
* A fix for solid midtextures not accounting for texture y offsets properly for non-Lower Unpegged/Peg Midtextured midtextures
* A fix for solid midtextures not accounting for "infinite" repeats (Repeat Midtexture + no repeat count set)
* ~~A fix for Effect 4 on Polyobject First Line making that particular linedef's midtexture solid in addition to making planes visible - this is not wanted if you want a polyobject with both visible planes and full intangibility.~~ Apparently they never did this anyway, don't mind me \o/
See merge request !104
Fix non-player objects having busted step-up/down on slopes
Why the fuck did I make this a player conditional in the first place holy shit
See merge request !103
RA menu can be opened if the game is modified, but Start can't be selected. (Obvious reason: so scripts to display info can be used easier)
Fixed the stupid background for messages in the Record Attack menu, it was bugging me
* Effect 3 (Peg Midtexture) is now accounted for properly, flipping the collision box position to match the actual rendered position of the midtexture
* Fixed incorrect application of y-offsets for non-lower unpegged midtextures collision boxes; +ve always goes up, -ve always goes down!
* Effect 4 now doesn't make midtextures solid for polyobjects at all - this "conflicted" with First Line having both Effect 4 (visible planes) and Effect 3 (intangible) simultaneously, where we kind of expect the first line's wall to not be made solid. This may be less of a problem in future SRB2 versions, but for now solid midtextures for polyobjects are disabled.
. tmthing can be NULL if called from PTR_SlideTraverse, so we should use slidemo instead
This fixes a crash that occurs in yet ANOTHER SUGOI map, involving bouncy walls next to sloped floors/ceilings
To understand: look at AjustSegs(void) in hw_bsp.c. It reallocates the vetex_t pointers for lines as POLYVERTEX_T pointers, and of COURSE things are gonna get wacky when you're casting pointers.
I dunno how resilient the FLOAT_TO_FIXED solution is or whether it'll be netgame compatible (yayyy float precision loss) but it's not like our builds are netgame compatible with themselves
* The NiGHTS drone had a single tic of visibility when you hit the goal, which is evident stepping frame by frame through http://gfycat.com/ComplicatedComposedAoudad (the contents of which may or may not make it into 2.2).
* When completing a NiGHTS stage with a non-zero link, the link could flash up in the final few tics before the fade to black. This just checks for player->exiting to make sure it shouldn't be shown.
OpenGL planes fix
This branch removes a specific hack in the OpenGL code for detecting if a plane is for the floor or ceiling of a sector. This it turns out fixes ceiling slopes in Boinciel's SUGOI map going missing. Though, It doesn't fix that other glitch with one FOF (must be unrelated).
If you want to test these fixes out properly, make sure working in-level sectors, FOFs AND also polyobjects all still work fine, sloped or not.
See merge request !97
Fof slope crash fix
This fixes yet another software renderer crash, this time relating to sloped FOFs: sometimes the renderer thinks parts of FOFs where the top and bottom heights are the same height are actually the bottom going through the top (in other words a negative height). This causes problems when drawing normal walls around such FOFs since the game obviously doesn't expect negative heights anywhere along the FOF - before slopes, the game could just flip around the top and bottom heights automatically with no problems. This branch also should fix crashes for all genuine cases of negative FOF heights when slopes are involved, I suppose.
Hopefully this stops FuriousFox's SUGOI map crashing for the time being, all seemed fine when I tested it out myself.
See merge request !96
-warp checking for invalid map names
I've noticed a bunch of new people getting the "Cannot warp to map 0 (out of range)" error when testing their custom maps. On asking what map name they used, it was clear they didn't use a MAPxx name at all. Sadly it was not obvious to them that other kind of map names are not accepted by SRB2, so I thought it best we make that more clear in-game.
SRB2 now gives you the error "Cannot warp to map \[your input\] (invalid map name)" if you used -warp with a param that is neither a MAPxx name or a plain number.
See merge request !99
Fix R_AddSingleSpriteDef's I_Error messages
Whoops, seems I forgot about this little branch. Basically this fixes how for a character's sprites, a full sprite lump name is displayed instead of just its sprite prefix in the "R_AddSingleSpriteDef: No patches found for [sprite prefix] frame [frame character]" message (unlike when it occurs for non-character sprites), resulting in something like "R_AddSingleSpriteDef: No patches found for PLAYC2C8 frame \^" which does NOT help custom character authors at all as it just confuses them instead. (for the record, the problem would actually with the ^ frame and not the ones displayed after "PLAY")
Oh, and the same problem is also fixed for this similar message: "R_AddSingleSpriteDef: Sprite [sprite prefix] frame [frame character] is missing rotations"
See merge request !95
for some apparent reason the compiler didn't like the while loop condition edit on its own (it complained about inline failures for P_MobjReadyToTrigger for some reason), so I had to add that extra bit above the while loop... and it was happy again, huh
If you want more specifics, sloped FOFs are to blame it turns out: sometimes the bottom of an FOF wall blocking a segment of an in-level wall column can be considered ABOVE the top part of the FOF there (yikes), and then the dc_y* values go offscreen, and then BOOM
Software crashes fix... fix
Fixes a typo introduced by merge request !75 that caused upper textures to set the wrong ceiling clipping value when not visible, allowing all sorts behind the walls to be visible. This is most noticable in GFZ2 when the inside of the tunnel section is visible
...probably a good idea to make sure this one doesn't introduce any MORE visual glitches by mistake (again, compare with 2.1.15 if possible)
See merge request !93
Fix for flats with transparent pixels on slopes
This fixes how R_DrawTiltedSplat_8 unintentionally allows the cyan pixels to NOT be considered "transparent" if after being remapped, depending on sector brightness and/or linedef type 606 colormaps, the result of remapping is not palette index 247 (the cyan we typically turn transparent). That is, the original colors from the source flat graphic are not checked, but instead the __result__ of coloring the flat under the respective colormap is checked for "transparent" pixels. This is only a problem for the tilted splat drawing function, not the regular one for non-sloped planes with cyan-pixel-using flats.
I found out about this bug from the issues Ritz was having with sloped 255-alpha translucent FOFs using transparent flats and his custom COLORMAP lump (and later when he applied a linedef type 606 colormap to the FOF) for his custom map. Thankfully he has some workarounds, but this should fix the code-side issues that caused his problems in the first place.
I also fixed stuff with another splat drawing function that's not currently used atm (maybe it will be in the future, if splats themselves are ever enabled again? *shrugs*).
See merge request !92
Skybox rendering offset fix for third person/alt view camera
Fixes the issue reported in this thread: https://mb.srb2.org/showthread.php?t=41729
I dunno if this will negatively affect any existing skyboxes in SRB2's own levels, that said. I tried out THZ2 and CEZ1 with this fix at least but I forgot to compare them with how they are in 2.1.15 so _*shrugs_*

OS X Makefile build setup
This merge request:
* Cleans up the OS X bundle resource location code and fixes a SIGSEGV and memory leak
* Simplifies and fixes the OS X desktop alert code, closing more leaks
* Adds the MACOSX build flag to the Makefiles, to allow building a binary (but not Mac app yet) of SRB2.
This is intended to make it easier for developers to build on Mac OS X, without having to pull in all of XCode. You can keep using CMake if you prefer.
To test, use `make -C src MACOSX=1 NONX86=1 SDL=1 NOASM=1` for a release build.
Left to do:
* Add a content bundling script to be run after building, and a flag to trigger doing that.
`MACOSX_BUNDLE` maybe?
* Somehow get access to a Mac running PowerPC and figure out how to build a multi-platform binary.
* Add the proper magic to compile using gcc if requested. (Right now, compilation is done via LLVM/Clang)

Gas jets, fan objects, springs and slopes
Whoop whoop whoop minor bugs that only get noticed due to weird experiments whoop whoop whoop
* For gas jets only: the object's standingslope is ALWAYS null. No drifting down the slope for you.
* For gas jets and fan objects: Now checks whether the player's top is below the bottom of the launcher, instead of its bottom. zdist calculation not affected, since it's signed and okay with being negative by about the height of the player.
* For all 3: the player's standingslope is NULL'd so the player isn't launched off at a wacky angle if they're standing on a slope then walk into the thing.

Remove i_net.c
The code in i_net.c doesn't actually seem to be used in SRB2. I was able to compile a build without it, and hosting and joining netgames worked just fine (well, as fine as they can with the current state of the netcode...).
The vast majority of code in the file seems to be contained in HAVE_SDLNET ifdefs, and I'm pretty sure SRB2 has never used SDLNET in a public build. The only bit not contained in that block is I_InitNetwork(), which just prints an error and returns false.
Do we really need to keep it around? If not, I say get rid of it. It seems like useless clutter that is just going to confuse people who are trying to understand the source code.

Re-factoring AA tree code from m_misc.c/m_misc.h into its own files
What the title says. The AA tree-related code now lives in the files m_aatree.c and m_aatree.h. Part of why I did this was to solve this m_misc.h/w_wad.h cyclic dependency problem (involving MAX_WADPATH and AA trees themselves) mentioned in the now-removed comments, another reason was ...only OpenGL uses AA trees at all, why include the relevent structs/functions/otherwise anywhere except where is necessary (which is very few files as it turns out)?
Otherwise, it just looked better on its own rather than mixed with all the other stuff already in the m_misc files. Not really important or anything affecting gameplay at all I guess.

- Now checks whether the player's top is below the bottom of the fan/gas jet, instead of its bottom. zdist calculation not affected.
- mo->standingslope is NULL'd so the player isn't launched off at a wacky angle. (I also did this for springs, since Prime mentioned it was a problem for them too.)
Some slope improvements/fixes (plus P_GetMobjGravity)
Dear Red, I did some things.
* Made the slope flag SL_NOPHYSICS actually have an effect like we wanted to, but didn't get around to implementing yet - activated by setting the slope's linedef flags to have ML_NOSONIC.
* Made downhill slope thrusts proportional to an object's gravity and friction.
* To make the above happen - seperated out the gravity value finding code in P_CheckGravity into a seperate function, P_GetMobjGravity. (p_mobj.c, p_local.h) I also made this function available to Lua.
* Turned those PANIC n console messages (which would inevitably be followed up with a crash, since we're accessing invalid memory immediately after) into a descriptive I_Error.
* Put the SRB2CB type-shimming behind an ESLOPE_TYPESHIM ifdef.
* Removed SPRINGCLEAN-ifdef'd code.
* Cleaned up some eosteric comments.
* NEW SINCE RED +1'd THIS: The teetering code now takes slopes into account pretty well. There are edge circumstances as outlined in commit 9d221f4f3f, but this is unilaterally better behaviour in every way and the teetering code was kind of a mess anyways.
* NEW SINCE RED AND ALAM +1'd THIS: P_ReverseQuantiseMomentumToSlope. Simple function that replaces the inverse angle stuff (which also wasn't using InvAngle, just ANGLE_MAX - angle - which is inaccurate!!)
Current testing files available at /toaster/slptst3.wad and /toaster/gravitytest.lua on the ftp.
I want to do more to the branch like implement SL_ANCHORVERTEX in the near future, but this is probably safe to merge in its current state.
See merge request !77
The whole thing needs a refactor in general, but it's almost 2am here, I need my sleeb, and this fix would probably break something with 2.1 climbing if I made it any more/less (depending on viewpoint) complicated.
Sectorlist traversal
MOM GET THE CAMERA
There's a LOT of code in the source that ended up mixing m_snext (the node for the next thing in the sector's thinglist) and m_tnext (the node for the next sector in the thing's sectorlist), so I renamed the following:
* m_snext ==> m_thinglist_next
* m_sprev ==> m_thinglist_prev
* m_tnext ==> m_sectorlist_next
* m_tprev ==> m_sectorlist_prev
Then, I changed all the instances where the code was trying to go m_thinglist_next on a mobj's touching_sectorlist (which would've just gone to the node for the next thing in the same sector, instead of the node for the next sector for the same thing). Notable samples:
* FF_SHATTER blocks now disappear the moment you go into their sector. You still can't give FF_SOLID to them because in that case they will still stop you if you never enter their sector at all (ie - clip on corners), but having them nonsolid no longer allows you to phase through entirely without busting them (which was the whole downside of making them intangible in the first place).
* You can now bump into multiple Mario blocks at a time, even if you're not exclusively in their sector.
* No more getting randomly stopped on the edges of bouncy FOFs.
* Landing on polyobjects might behave a little more consistently at the edge of their host sector.
* Teetering did a SHITTON of code that basically never got executed, and then had directly-blockmap-accessing code as a backup. The code was activatable by replacing the m_thinglist_next with m_sectorlist_next, but it behaved SUPER differently from what we're used to with teetering (if the player mobj's edge was JUST off the edge of a platform, you ended up in teetering frames - even if it looked like you could stand) so I ended up removing that section entirely.
Any objections?

Fixes and changes related to the act of setting up a level (in other words, setup fixes)
Changes made in this branch so far:
* a REJECT lump of zero length (NOT to be confused with a REJECT lump of non-zero length with all-zeros, just to clarify) should no longer cause problems with netgames and otherwise. The game now checks if the lump exists, has the right name, and length is not zero - if it fails any of these, the REJECT lump is not loaded and P_CheckSight won't be allowed to use it. This means ZDBSP (no reject) should be safe(r) to use now!
* there's now a simple devmode-only message (requires "Setup" mode) if a sector is found to have no lines at all during setup. It's a far cry from the plot to I_Error the game I once had for that unsusal scenario, but such a level still works anyway so whatever.

FF_REVERSEPLATFORM clipping
Ran into an issue whilst testing out one last feature (there's always one more...) for flat_alignment_revamp. This is a backported fix.
The bug was such that if you're falling through a platform with FF_REVERSEPLATFORM and not FF_PLATFORM, you'll be pushed downwards such that your head is against the bottom of the FOF. This just checks momz is greater than zero if it has FF_REVERSEPLATFORM to make sure it's okay to set ceilingz. (OR the alternative in reverse gravity.)
No test map because this was originally done for internal. Instead, test it on the other branch's test map.
See merge request !83
Software crashes fix
This branch SHOULD fix the many crashes people have reported lately that all point to the software renderer. Simply put, the software renderer allowed stuff to be drawn out of the screen even though that wasn't safe, and even the existing checks to prevent that didn't work.
If you saw me worrying about the sky HOMs I discovered in AGZ earlier in the commits for this branch, don't worry - it turns out that issue already existed in 2.1.15's srb2win.exe (and probably srb2dd.exe too) anyway, the changes in this branch didn't cause them. Hopefully nothing else broke then.
See merge request !75
Also, the teetering angle on slopes is now FRACUNIT/2 because there's literally no way to stand still on a slope that steep unless it doesn't have physics.
This means the current skewing-by-default effect isn't changed, and OpenGL's equivalent code doesn't have to be touched since apparently it was already like that.
This should mean that maps built with ZBSDP (no reject) should have less or no problems in netgames compared to the standard ZenNode maps now, hopefully. =)
note: once this is merged into internal, you should probably remove me from "programming assistance" so i'm not duplicated for no clear reason. unless you want me to slowly take over every section in the credits >:3c
"frontsector" in this part of the code isn't actually the polyobject's sector for back-side polyobject segs, it's the in-level sector the polyobject as a whole is being rendered in it turns out.
Red apparently left in code for single-sided linedefs to NOT skew their midtextures ...but it doesn't work because it doesn't stop the skewing code from running instead, regardless of whether Effect 1 is on or not. If it's decided single-sided line midtextures shouldn't do this though, the non-skew code could just as well be thrown out lol (or something else I guess?)
When I first wrote this, I thought the .h file that contained a function declaration needed to have the same name as the .c file the function was in. Now I know that's not the case, off to p_local.h with you.
Two interesting points of note:
* The touchspecial sector flag seems to actually do its job now.
* Detection of sectors with polyobjects in seems to have done this incorrectly, but this doesn't mess with anything about touching the polies themselves so it seems to really only handle edge cases where the polyobject was too close to the border of another sector (which would've likely made rendering glitches anyways).
* There was a whole swathe of teetering code that was basically never run properly because of this mistake. I did a simple fix at first, but you started teetering whenever you were slightly less than your radius away from a sector's edge, which was completely different and undesirable behaviour. Instead, I cut out the code that was never running, and just left the hacky method in instead since it was more accurate to what we want in general.
Issue was caused by attempting to traverse the sector's thing-touching-list across all the things in the sector (which would inevitably have the same sector as the first node in mobj->touching_sectorlist) instead of traversing the thing's sector-touching-list (which has the same thing but different sector references).
I wonder how many times AJ copypasted this code with absolutely no idea why it wasn't working properly. I'll figure that out tomorrow, maybe set up some compiler macros so this mistake is never made again. For now, I must sleeb.
Behaves ALMOST as you'd expect. It gets the z position of the slope at the player coordinates when it comes to the sectorlist check (which is first), though, so there's a few oddities that are amplified with steep slopes:
* If the slope's sloping away from you at a steep angle, you might not be able to step down onto it, but you won't teeter (because it's at a step-down-able height if it extended to directly beneath you)
* If the slope's sloping towards you at a steep angle, you might end up in teetering frames when you're able to step down onto it (because it's NOT at a step-down-able height if it extended to directly beneath you)
HOWEVER, it would be pretty obnoxious to hold back code which is functionally superior in every way otherwise, and it doesn't really seem like there's a good way to get that checked tbph
Also updated any relevant project files that I can think of to include the new files, as well as the makefile of course. Some of the other project files haven't been touched in years so I'll leave those alone ...unless someone objects
Basically this makes sure numwadfiles is updated before loading the SOC/Lua scripts, so if a Lua script calls COM_BufInsertText with the contents "addfile scr_mysticrealm.wad" it can't overwrite the last written wadfile slot! Not that COM_BufInsertText really should be used like that to begin with
*Didn't take into account object scale
*Doubled force when on the ground (ignore what the comment of the line I moved says, it was relevant for slopes...)
This also led to a mistake with slopes, where I was double-multiplying by the gravity constant to get half (because of a quirk of numbers...)
Also took the opportunity to nuke or otherwise neuter a bunch of Kalaron's bizzare ramblings (most are questions which have long-been answered by Red's efforts) at the same time.
*The No Physics flag now works (Red, you might want to doublecheck this to see whether I haven't missed any eosteric stuff out). Going downhill is a little bumpy, and I'm not sure whether that's good or not. Someone help me out here?
*The SRB2CB typeshims are now behind #ifdef ESLOPE_TYPESHIM instead of #if 1 for easier disabling.
*Slopes' downhill thrusts are now scaled with regards to object gravity. This is actually untested in gravities other than normal and reverse normal but it's one line which can be easily reverted in that circumstance. I also checked with MI to make sure this is how it's calculated elsewhere, so fingers crossed this doesn't cause any edge cases.
*As a consequence of the above point, there's now a function in p_mobj.c/h that returns an object's internal gravity - seperated out from the logic of P_CheckGravity, which really didn't need to be so monolithic. Multiply by global gravity to get the thrust. This should probably be available to Lua somehow, but I have absolutely no idea where to start with that. Wolfs, maybe?
Non-comprehensive test file available at /toaster/slptst3.wad on the ftp.
Do we really need to keep it around? If not, I say get rid of it. It seems like useless clutter that is just going to confuse people who are trying to understand the source code.
* -lSDL2_mixer is already added to SDL_LDFLAGS by default, unless NOMIXER=1 is set
* -DSDLMAIN should also be added to OPTS by default for MINGW=1 builds, unless NOSDLMAIN=1 is set
NiGHTS hotfix
Fixes the following issues relating to playing as NiGHTS Super Sonic that apparently popped up between 2.1.14 and next (mostly due to the changes to SRB2's trig stuff it seems):
* Super Sonic drifts to the side at some angles around an axis, and is unable to go directly upwards or downwards as a result
* Drilling to the side when on the ground causes the drill sound to constantly restart
* CEZS's start not actually being lined up properly with the first axis means the player is not able to go backwards along the track (because the player is not actually aligned with the track properly, preventing you from touching the attached line transfer)
* trying to hug some walls such as the tall wall before the library section of CEZS allows Super Sonic to go through them
These fixes needs proper testing before this branch can be merged in, in case they accidentally break other things as a result or something.
See merge request !71
Basically I kind of worked around any potential trig inaccuracies by not using the player position directly for setting momx/momy. This way, if player->angle_pos == player->old_angle_pos, momx/momy are zero
Demo replay fixes
Changes made/bugs fixed in this branch:
* Replay camera is now controllable when climbing (https://mb.srb2.org/showthread.php?t=38668), and in waterslides
* localangle (read: the angle between you and the camera, I think) now doesn't change during demo replays in most situations, unless the player is in analog mode. Exceptions include zoomtubes and NiGHTS super
* Replay camera now doesn't act silly if the player is in analog mode (assuming you also recorded it in that mode to begin with, anyway)

DO NOT MERGE THIS INTO THE INTERNAL REPO. This is a temporary 2.1.15 only fix. This commit allows an optional boolean for tan(), which when true will automatically shift angles by ANGLE_90.
the most common condition (correct drawing) shouldn't be last, however it can't be first without making the conditions longer anyway.
it's a nitpicky thing, but this is the renderer we're talking about here.

Previous overflow fix resulted in extra tall FOFs disappearing up close (see: ERZ1's elevators at start)
This works "better" in that only some lighting bugs and really really finicky visual glitches show now. I give up trying to totally fix this stuff dfsdfgdgf
One more name in the credits
I probably messed up by making toast_credits based on master instead of next. If that's blocking, just delete this branch and I'll re-do it. It's a single line, though - shouldn't exactly matter so much.
Could probably stand to be merged into Internal as well, since I hadn't actually worked on any textures when we'd updated the credits there.

Fix portal and plane/sky interaction
More portal-related fixes:
* Fixes rendering issue 4 from issue #21 (Slope planes render with wrong height values when visportals are visible on-screen)
* Fixes sky rendering through portals, so that the sky you see through each portal is what you'd expect to see if you were actually there. Easiest way to see what I mean is through sky 22's planet, in a map with portals at 90 degrees to the other sides respectively (the example map on the wiki for ld40, for instance).

The idea is for the layman Lua user to understand better what range of values to use for mobj types, states, sfxs, player #s etc. Additionally, mobjinfo/states/sfxinfo/hudinfo tables all now have actual bound checks when accessing/editing them. Yikes, why didn't they have any before?!
Slope fixes
This branch fixes the following slope-related physics and rendering bugs:
* Rings in multiplayer stages respawning inside slopes (even despite being able to spawn ABOVE them on map load)
* Player starts spawning players inside slopes
* Elemental flame trails not appearing if a player spindashes UP a slope; see issue #21
* Dying players "jumping" off slopes to the side if they were previously standing on one
* Some issues with FOF slope rendering
* Various issues with sprites displaying through walls adjacent to slopes
Other features added:
* Objectplace now supports slopes (this is Inuyasha's doing)
* Automap in DEVMODE now supports slopes (my doing)
Just making this merge request now rather than later, ~~in case I decide not to make any more fixes for the time being~~ (this branch doesn't seem to want to die lol), and so we can get these merged in as soon as the code's all been checked over.

xorshift* PRNG
This needs testing to ensure I didn't mess anything up switching function names around.
Our PRNG sucks. This is probably obvious. I wish I had known better at the time I implemented it, but oh well.
The replacement is an xorshift* PRNG variant with period 2^32 - 1 (meaning that the PRNG state will loop after four billion calls ... that's not likely to happen), versus the old PRNG's period of about 2^22 (?). The output is also much more random and less predictable; the old PRNG would fall into a predictable loop of output after about 4000 numbers were generated, which isn't much.
The PRNG here also outputs numbers as fixed point from [0,1) (that's 0 to FRACUNIT-1, in other words) instead of single bytes at a time. This makes it much easier to calculate things for, say, P_RandomRange and P_RandomKey. A new macro, P_RandomChance(p), is now in use that returns true _p_ percent of the time, where _p_ is a fixed_t probability from 0 (0%) to FRACUNIT (100%).
This doesn't affect netgames at all; the code for seed saving and restoring is identical (aside from a check to prevent seed being set to 0, which breaks xorshift PRNGs). Demos break, but A: _duh_ and B: they're already broken by all the changes to physics to accommodate slopes.
P_Random is deprecated in Lua, as the function was renamed to P_RandomByte. Aside from that, nothing special.
See merge request !64
* add skidtime, which we forgot before 2.1 release apparently
* change tics from INT16 to INT32
* change eflags from UINT8 to UINT16
* change actionspd/mindash/maxdash from INT32 to fixed_t
Until we use something besides Native MIDI to play
back MIDI music, MIDI volume changing is disabled
since it causes way too much of a damn headache.

Fix for teetering on PolyObjects
So... somebody goofed and didn't realise PolyObject sectors could be added to the sector node list for each object (which is referenced by mobj->touching_sectorlist), via their linedefs if they are nearby the player (yes, PolyObject linedefs are special and get to move about the level). As it turns out, this allows even INTANGIBLE PolyObjects to make you teeter in a seemingly inexplicable way.
What is happening is that PolyObject sectors, when they are added to the mentioned lists, are then checked under normal sector teetering conditions - if the player is above the floorheight by 24 FUs, you're officially teetering unless stated otherwise. The actual PolyObject teetering code can't help you here if the conditions are right, especially if they're taller than 24 FU in height.
There are a number of things wrong with the teetering code in general that I'd like to sort eventually, but at least now teetering on PolyObjects is fixed at last ...right? Please check the branch out if you can to check this, obviously.
See merge request !54
Fixes for patch scaling and V_FLIP usage
The following issues are fixed by this branch:
* a patch using both scaling and V_FLIP does not appear in the "correct" place on the screen. Thanks to LJSonic for pointing this out to me on 'fun
* Scaled and/or V_FLIPed patches wrap at the left/right screen edges even though they're not supposed to. V_FLIP patches at these edges may also crop the wrong side of the patch if they're at the right edge.
See merge request !60
Some fixes for portals
Specifically the following things are fixed in this branch:
* a memory leak resulting from not clearing away clipping-related arrays each tic you view a portal
* a very specific crash to do with portals sometimes (unintentionally) using a hack on drawsegs that don't actually belong to them ...which results in a crash if the drawsegs in question have midtextures. I reported it on the MB a year ago, with a test map included there: https://mb.srb2.org/showthread.php?t=38199&page=4#79
* another specific crash to do with mirrored (horizontally flipped) sprites that are scaled, particularly when you cover up the left edge of them via portals at the least. Needs more testing to be absolutely sure this is fixed, and is also reproducable in the test map linked in the post above
May be fine to merge changes into master too, I don't really know exactly
See merge request !42
Camera fix
This fixes the third person camera being silly around intangible PolyObjects, particularly the fact they can affect the camera's floorz and ceilingz even though I see no reason why they should do so.
Also a good reminder that POF_SOLID is the same as POF_CLIPLINES and POF_CLIPPLANES combined, which is probably how this issue came about to begin with. Can't say that with certainty of course.

P_RandomChance is now a macro for something that should happen a
certain percentage of time.
P_SignedRandom was moved to a macro. Nobody cared.
# Conflicts:
# src/p_inter.c
This actually passes most diehard tests, as opposed to the old RNG.
It's also similarly fast.
Internally the PRNG generates a fixed point number from [0,1) now,
which makes P_RandomKey and P_RandomRange much easier to
calculate. P_Random is just a simple shift, as well.
Also, the lack of floating point math in P_RandomKey and
P_RandomRange now is probably for the best.
Also makes comptime.bat work with git if able.
Development builds will now show the branch and the SHA1 hash of the revision. Also been tested to work with subversion, where it displays "Subversion r####". You know, just in case.
There is a caveat to this: The first time EvalMath is used, a
deprecated function warning will be shown to the user that tells
them to use _G[] instead.
This reverts commit 9d36cf37bd.
