OLD SPECIAL STAGES:
* Spheres in old special stages instead of rings!
* Individual timers in old special stages instead of a global one!
* Old special stages use a variant of the NiGHTS HUD now!
* Special stage damage in old special stages loses 5 seconds of time instead of 10 rings/spheres!
* All damage gained through old special stages is converted to special stage damage! As a consequence, the special spikeball has no need to be special anymore.
* Made emerald gaining function be based on special stage number rather than gained emeralds!
* Consistency with...
NiGHTS SPECIAL STAGES:
* Spheres now flash in bonus time. https://cdn.discordapp.com/attachments/400761370800422922/452590553100713984/srb20032.gif
* Sphere and ring mapthingnums are now less fucked up in 'em. (Rings are 300, same as usual, while Spheres are now 1706 replacing NiGHTS Wings.)
SPECIAL STAGES IN GENERAL:
* useNightsSS is now dead. Each individual special stage is now assessed for NiGHTS-mode behaviour based on maptol & TOL_NIGHTS.
* CRAWLA HONCHO\n CAN NOW BE\n SUPER CRAWLA HONCHO end tally modification now also includes a mini-tutorial on turning super. https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif

RANDOM BS:
* Turn super with the spin button instead of the jump button!
* Followmobj now correctly set with P_SetTarget instead of pointer assignment.
* Emerald hunt uses new sprites!
* Made unlock noise different from emblem gain noise! (It's the CRAWLA HONCHO CAN NOW TURN yadda yadda sound from S3K now.)
Move old fix for too large maps having rendering issues from R_CheckBBox to OpenGL's HWR_CheckBBox
From what I know, this effects at least Aerial Garden and Seraphic Skylands
* Facestabber statues, of both the suspicious and non-suspicious kind.
* New object type for the end of grabbable chains.
* I moved my compilation .bat file to my Releases folder, so it should .gitignore .bat's.
* Random extra stuff.
* Blue diagonal springs, because that gap is very, very odd.
* Improved A_SpawnFreshCopy.
* Tweaked P_LookForEnemies for consistency's sake. (Previously, it was impossible to make a spring that could neither be homing-attacked or attraction-shotted.)
* Behaves a bit differently to the one in DSZres.pk3.
* Can now punch DSZ mines!
* Also has mapthingnum 126 instead of 610.
* Some other mapthingnum changes.
* DSZ2 stalagmite is now 1009, formerly 999.
* Big DSZ gargoyle is now 1011, formerly 1009.
* Make the MF_PAIN stuff ONLY depend on mass, using the bottom 8 bits for the type and the custom sound in the upper ones.
* A bunch of cleanup of random other stuff, including an unused Deton state and an unused Jetty type's sprite.
* Made Facestabbers take two hits and have associated pain/death animations. No other changes, just wanted to make sure THIS was done.
* Move Bubblebuzz-related stuff to go alongside the secret badniks and etc.
* MF2_INVERTAIMABLE. Inverts whether P_LookForEnemies can get at; replaces a hardcoded thingy.
* MF_PAIN and MF_MISSILE now support setting damagetype via their Mass parameter. The two existing conflicts - the fuse setting for the grenade weapon ring and the Cybrakdemon napalm bomb - had these moved to other free parameters.
* A_ConnectToGround is EXTREMELY useful for palmtrees and stuff.
* Some other, relatively hacky A_ functions.
* (Unrelated) Remove the need for a "Mario block mode" for the token by making it natively compatible.
* Spikes and their time-offsetting via that Lua script sphere made. Also allow for wallspikes to do it via their angle/360.
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.
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.
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.
Only use glCopyTexImage2D when first creating the screen texture, use glCopyTexSubImage2D anytime after that as it does not define a new texture each time.
Flushing of the screen textures has been implemented for when the screen size changes (so that the screen textures don't stay at a wrong size) and the game is closed, I believe they would leave a memory leak before.
The Far clipping plane did not need to be nearly as high as it was, the new value is 32768, which I suspect is about how far software can render before it completely falls apart.
It is desirable to increase the near clipping plane to between 6-10, but it can introduce more issues with close geometry not being drawn when the player or camera is scaled or viewheight is set to MIN in first person view. It would also stop sprites from being drawn ever so slightly too early, but this isn't too much of an issue and isn't too noticeable with those values. Might look into scaling near clipping plane in accordance to camera scale in the future.
The reason for wanting to increase the near clipping plane is because the small value can cause very noticeable Z-fighting where there shouldn't be on older GPU's, usually Intel ones, that don't support 24-bits for the depth buffer.
- controllable strengths between 0-31 for COLORMAP lump like before
- arbitrary colour indices in the palette via TRANSMAP lumps, with strengths 0-9
- exposed to Lua as v.fadeScreen(color, strength)!
* Remove last vestiges of V_STATICPATCH.
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
* 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.
* 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
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!
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.
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.
See merge request !78
****
* 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
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?)
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
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
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).
MI's unimportant code cleanup
Just removing a bunch of unused variables/function prototypes from the source code and similarly minor stuff, nothing here should change gameplay much (if at all).
See merge request !71
Revamped Level Select (platter view)
Seriously revamped every level select instance in the game to use a more attractive and easier to navigate platter view, including:
* Game CLEAR! save (Title/Pause menus)
* Secrets Menu (including custom ones)
* Record Attack/NiGHTS Mode
* Server creation (Online/2P)
* MP Pause level select (Online/2P)
As a result, the layout of the last three above menus has been changed to varying degrees of difference.
Also, bonus feature: using level select (or MAP MAPxx without -force) in Co-op multiplayer won't reset your score, will keep any lives you have above the startinglives variable, and will not take away all your emeralds. The -force thing prevents both warping directly to special stages to rack up the emeralds AND ensures there IS a way to start a new game.
Check out <root>/!LatestSRB2Files/srb2win_branch_levelselect.exe with the latest patch.dta to see more.
Also, LF2_WIDEICON lets you do this. https://gfycat.com/MenacingClearAngora
See merge request !68
*P_LookForEnemies is now side-effect-less and only provides a pointer to the found mobj
*player-jumping is dead, long live PF_STARTJUMP
*per Mystic's request, CA2_GUNSLINGER has a targeting icon. It also has a more restricted vertical aiming range.
*mobj for this is in the game as requested
*fast teetering animation flag
*general code cleanup
Other notes:
* on second thought I'll keep the hw_clip functions' gld prefixes rather than HWR, not like it matters either way
* despite the extra lag it does fix the issues with translucent walls and such when displayed at different vertical angles, such as with the GFZ1 waterfall
Other notes:
* Renamed all new functions to have HWR_ prefix instead of gld_, for consistency
* HWR_FrustrumSetup and HWR_SphereInFrustum are disabled and require HAVE_SPHEREFRUSTRUM. This is because 1) SRB2CB did not need the code, so presumably neither will we, and 2) there are some OpenGL API functions used there that due to our way of using OpenGL we don't use outside of r_opengl.c, which makes dealing with HWR_FrustrumSetup complicated in theory
* The new clipping functions are not added to OpenGL's "main" rendering code itself just yet, they're just available to use now once hw_clip.h is included
Hardcoded VAda Flickies
Many thanks to MI for his help, even if he has sinful opinions on what the collection of creatures should be called. ;P
* Flickies are now handled via A_FlickySpawn instead of hardcoded in P_KillMobj, so there can be mobjtypes with MF_ENEMY which don't create flickies, or other mechanisms which can much easier.
* Added map header "FlickyList" (aka "AnimalList") parameter, which can either be set to:
* A species (eg: "Rabbit" or "Bluebird", amongst 17 currently supported types in dehacked.c table FLICKYTYPES - including the seed from Sonic CD, which isn't limited to 'soniccd on' in the console now)
* Any valid mobjtype that isn't MT_NULL (eg: "MT_FLICKY_GHOST")
* A comma-seperated list of either of the above, up to 64 entries long (eg: "Cow,MT_FLICKY_SPIDER,Chicken")
* "All" - sets behind-the-scenes stuff to use every 'normal' type of flicky in FLICKYTYPES (a distinction which can be utilised to hide secret level flickies where they wouldn't be appropriate for the main game)
* "Demo" - sets behind-the-scenes stuff to use the five flickies closest to the species used in the game's long history.
* "None" - prevents any flickies from spawning.
"Demo" is functionally the default value if you don't include a FlickyList parameter in the header at all.
Of note, a bunch of functions are now created:
* A_FlickySpawn - spawns flicky.
* A_FlickyAim - aims for area near target, but not directly on them - turns around when hitting wall
* A_FlickyFly - flies/swims around target (calls A_FlickyAim)
* A_FlickySoar - hacky alternate fly (calls A_FlickyAim)
* A_FlickyCoast - slowing down before going off again
* A_FlickyHop - fracunit-scale precision for A_BunnyHop
* A_FlickyFlounder - A_FlickyHop with randomisation
* A_FlickyCheck - State-setter for falling, or being on-ground
* A_FlickyHeightCheck - State-setter for falling, or being below a certain height relative to target
* A_FlickyFlutter - A_FlickyCheck, but with a slow fall/movement (calls A_FlickyCheck and A_FlickyAim)
I don't need to enumerate the object types and states that have been added, do I?
Oh yeah, I also made it so get_mobjtype's failure value was MT_NULL and prohibited SOC from editing the properties of it to compensate.
IN ADDITION: Killed "soniccd" console command, since it made things more complicated and honestly being able to specify Sonic CD seeds in the level header is a better option.
See merge request !60
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
this fixes a crash in (old) GFZ2 at the ramp as a result of creating pv1/pv2. This probably means before pv1/pv2 there could have been some silly typecasting from vertex_t to polyvertex_t to get fixed vertex coords and such...
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
Animated sky support
What it says on the tin: skies can be animated textures now. Just set them up as normal animated textures (keeping in mind the starting texture still has to comply with the SKYn/SKYnn/SKYnnn naming format) and hey presto, your sky animates.
See merge request !34
* flips the sprite ala MFE_VERTICALFLIP except you don't need to flip the direction of gravity for the object just to draw upside down
* stacks properly with reverse gravity
* That hacky anti-NiGHTS-deaxisment code I commented out because I thought it was visual only? Reimplemented in a way that is both more and less hacky. It's identical in result to the original code, but takes a roundabout method to get there.
* Sprite references for SUPE, SUPZ and NDRL are removed because they are now unused.
* Helper's flashing conditional is restructured to do less flag swapping.
* The check for super setting FF_FULLBRIGHT is limited to MAXTRANSLATIONS now, and also correctly takes into account MAXSKINCOLORS == SKINCOLOR_SUPERSILVER1.
* NiGHTS collision bounds aren't hardcoded anymore.
* NiGHTS link will never display when leaving stage.
* Slightly tweaked rules for the supercolor setting when doing a NiGHTS transformation, but only meaningful for setting FF_FULLBRIGHT.
* Several new supercolours.
- SKINCOLOR_SUPERSILVER1-5 (for fun) - "Silver"
- SKINCOLOR_SUPERPERIDOT1-5 (nyeheheh) - "Peridot"
- SKINCOLOR_SUPERCYAN1-5 (for fun) - "Cyan"
- SKINCOLOR_SUPERPURPLE1-5 (for fun) - "Purple"
- SKINCOLOR_SUPERRUST1-5 (mecha/metal sonic) - "Rust"
- SKINCOLOR_SUPERTAN1-5 (shadow/silver the hedgehog) - "Tan"
* SKINCOLOR_SUPER1-5 renamed to SKINCOLOR_SUPERGOLD1-5, one index for darkest is changed - "Gold"
* SKINCOLOR_TSUPER1-5 renamed to SKINCOLOR_SUPERORANGE1-5, ported properly to the new palette - "Orange"
* SKINCOLOR_KSUPER1-5 renamed to SKINCOLOR_SUPERRED1-5, ported properly to the new palette - "Red"
* new S_SKIN attribute - supercolor - uses an entirely different function to get the names (R_GetSuperColorByName instead of R_GetColorByName)
* a fun little secret - typing "god on" in the console whilst super makes the player hyper (visual only, no sparkles - just rainbow flash) - can be removed if no fun is allowed
* Electric sparks coming off entire body instead of bubbles coming out mouth
* Different sounds.
* Different icons.
These sprites are currently local only, but I'll be doing a lot of asset updating this evening since Rob asked me to so it won't be long until you can get them.
* NAMEcL refers to a frame which is seen for the entirety of an object's left side.
* NAMEcR refers to a name which is seen for the entirety of an object's right side.
* NAMEcLcR does both sides.
* Having just a NAMEcL requires you to fill in the opposite side either with NAMEcn where n is 1 and 5 to 8 OR fill in with a NAMEcR
* Switches down the centerline of the object instead of at the ANGLE_202h interval for normal sprites.
* Characters were selected for 1) ease of use and 2) not getting in the way of adding support for zdoom's totally bananas 16-way sprite system at a later date if we so choose
