Spindash dust
Charging a spindash kicks up dust, we all know this feature was dying to get in at some point. Bubble and flame forms of spin dust are included from FSonic, for underwater and elemental respectively.
Oh, and as a bonus I reorganised the spindash/spinning/other ability2 stuff code to look a bit neater and more organised.
New resources:
* MT_SPINDUST - the object
* S_SPINDUST1 to 4 - the normal form's states
* S_SPINDUST_BUBBLE1 to 4 - the bubble form's states
* S_SPINDUST_FIRE1 to 4 - the bubble form's states
* SPR_DUST - the normal form's sprite set (uses frames A to D, just pinch FSonic's sprites really)
* SPR_FPRT - the flame form's sprite set (frame A only)
SF_NOSPINDASHDUST disables spindash dust for a character

Sprite2 changes
Some stuff!
* Lua access to sprite2.
* Introducing new Lua-exclusive function, P_IsValidSprite2(mo, spr2). Basically just a wrapper for (((skin_t *)mobj->skin)->sprites[spr2].numframes > 0), useful for creating custom sprite2 defaulting functions since hooking into P_GetMobjSprite2 wouldn't be worth it.
* FF_ANIMATE support for sprite2s. The var2 of the state works identically to normal FF_ANIMATE, but var1 is completely disregarded - it just runs all of the frames available to that one sprite2 animation set.
* As a result, a bunch of states which were either not previously animatable or had animated at constant speed now get animation without state changes.
* P_SetMobjState now supports sprite2 defaulting like P_SetPlayerMobjState does.

Damage control + Match rebalancing
This is two branches in one since while I was working on damage-control's changes months back, I felt it was best Match rebalancing was merged in here too (thanks JTE for helping me do so).
Changes from damage-control:
* `player->health` (formerly the "HUD copy" of `player->mo->health`) is now `player->rings`, and is also now the player's actual ring count.
* `player->mo->health` (formerly rings + 1) is now always 1 when alive, regardless of ring count; if player with rings is damaged, this is untouched.
* P_RingDamage now includes ring spilling code.
* P_ShieldDamage now has a damagetype argument, allowing me to remove the last MT_NULL hack left in from the pre-damagetype days that I forgot about.
* The old "switch-to-seestate" enemy damaging behavior in P_DamageMobj has been removed. This was a Doom left-over and doesn't really affect SRB2's enemies anyway - see, Doom enemies had a random chance of using seestate or painstate, SRB2 enemies always use painstate.
* Other minor efforts to reorganise damaging code and have it make more sense, but otherwise nothing that should affect gameplay in general.
Changes from match-rebalancing:
* New weapon/ammo dropping behavior: if you have the weapon panel + ammo, you drop the panel (but not the ammo); if you don't, you just drop the ammo.
* New Match ammo consumption: Weapon rings can now be fired with no rings at double the ammo cost.
* New emerald behaviour: collecting all 7 emeralds no longer turns you super (read: Match super is dead now) but instead steal points from enemies and gives you and teammates invincibility + sneakers
* Tails ringslinger buff: Any character with CA_FLY will now throw rings 1.5x as fast.
See merge request !28
* All Lua-originated sprite2 settings are now forced through P_GetMobjSprite2. Makes sense because of SPR2_JUMP, which none of the main characters have sprites for yet all use.
* Cleaned up P_GetMobjSprite2 to not set irrelevant, otherwise-unused variable.
(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)
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)
See merge request !124
* Bubblewrap shield bounce now no longer allows thokking post-bounce, but still allows bouncing
* plus a bunch of tiny changes to clean up code around the place.
* Some shield sounds swapped (can be reverted later).
* Partial implementation of S3K shield abilities.
* The ability to elemental-groundpound onto gold monitors without going straight through them.
* Force shield ability removed because nobody could agree on it, we'll keep it blank until another idea can get through the disagreement juggernaut.
* shields give you 1000 points
* redundant shields don't make you puase
* checkpoints give you 2000 points
* falling down a deathpit is just falling, not bouncing
Fixes to horizontal spring collision
Fixed various issues arising from collision with exclusively horizontal springs. Thamks to @Inuyasha for the heads up! Of note:
* If you hold down your jump button whilst jumping into it, you no longer immediately use your ability.
* Characters with (CA_DOUBLEJUMP && CA2_MULTIABILITY) or CA_FLOAT or CA_HOVER no longer lose track of their jump count.
Also:
* Upped the strength of info.c's red and yellow horizontal springs.
See merge request !41
FF_ANIMATE additions: globally synced animations
FF_GLOBALANIM = makes the animation synced to the level's timer, so all objects will display the same frame at the same time
I mean, doesn't that look so much prettier?
There's also some changes to FF_MIDDLESTARTCHANCE (FF_ANIMATE behavior was split due to not acting consistent between that and SPR2 behavior).
See merge request !46
* introducing the new friend, SH_FORCEHP (which is used as a bitmask to get the extra hitpoints of a force-shield user)
* P_DamageMobj now considers the unimplemented shield constants as well as the implemented ones.
* When not pressing any direction, you now go backwards by default - to emphasise that this is primarily for defensive, not offensive, purposes.
* The camera can now handle the player going backwards without them going completely off-screen.
* Fixed some overzealous checks.
* The spinfire ring is now capable of damaging enemies. (god, what a terrible hack this is)
* When ground pounding, you now bounce off the floor a little bit to make the ability less spammable.
* The Dodge Dash
* Allows you to dash - no control, no falling, no key response - for 2 + (number of extra shield hitpoints) tics.
* If you're holding movement keys down, you dash in the direction you're holding - otherwise, you dash directly forward.
* You're spinning (spindash spin, not jump spin) until your dash is over, then your momentum is cut down significantly and you end up in falling frames.
* It may not necessarily be super useful for Sonic, but it helps the other characters.
* http://gfycat.com/BogusFailingFritillarybutterfly
* http://gfycat.com/PoliticalIdealisticBallpython (outdated speed, shows any direction)
* GFZ3 Eggmobile's laser won't change its angle when you move left and right anymore.
* Changed because its ability to move quickly was extremely punishing for new players (see ProJared's youtube video on the matter).
* http://gfycat.com/PassionateUnknownAgama (the twitching on the third laser has been fixed since this was recorded)
* GFZ3 Eggmobile will, when too far away from the ground and moving upwards, slow itself down vertically.
* This was punishing and annoying for both old and new players alike.
* http://gfycat.com/ShabbyAncientEarthworm (old values - the typical settling height is slightly lower now)
(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.)
* Camerascale, shieldscale, height and spinheight are now player attributes which are set to the skin attribute on skin change, not read directly from the skin.
* P_GetPlayerHeight and P_GetPlayerSpinHeight are now macros instead of functions.
* Extra protection against switching to a locked skin.
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
Also, the particles made via spindashing in shallow water are now located behind the player. This does move the running particles too, but that's okay.
* Fixed bug where being pushed off a platform whilst charging a spindash would leave you in your charging frames instead of your rolling ones when you hit the ground (http://gfycat.com/MassiveThreadbareItalianbrownbear for how it works now, http://gfycat.com/MarvelousEnlightenedAuk is how it used to work)
* Fixed bug where spindashing on top of a bubble spawnpoint led to you being able to move around in spindash frames (no gif since obvious desired behaviour is obvious)
* Spindash animation speeds up the faster you'll shoot off.
* The spin charging mechanism is now scale-independent, and only multiplies by scale when shooting off - less FixedMul calls, and potentially deals with weird quirks of changing scale whilst spindashing that nobody's discovered because there's no place to find that in the main game!
Also:
* Climbing animation defaults to rolling instead of walking, because what.
* MF_AMBUSH is now MF2_AMBUSH, because it's something you turn on in a map editor, not with a SOC definition.
* Where MF_AMBUSH was is now MF_PAPER.
* MF_PAPER accesses all the stuff I did previously in this branch...
* ...as well as turn on paper-thin collision detection between mobjs, which I've gotten working but isn't perfect but it's still good enough for non-solid objects!!
* 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.
* 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.
* if you can turn SF_SUPER, flash your skin's supercolor, otherwise be your normal color
* if your skin doesn't have a SPR2_NGT0 (horizontal fly), use Sonic's (this will hopefully be replaced by 2.2 with sprites of NiGHTS themselves)
* MT_NIGHTSCHAR made irrelevant, everything follows actor->target instead of actor->target->tracer now
* emerald is now player->mo->tracer instead of player->mo->tracer->target
* nightopian helpers flash for the 35 tics before they disappear
* nights capsule makes boss explosions/noises now (i can change it back i just like it better)
* drill off into the sky instead of fly up in floating pose (but no noise yet)
ALSO:
* default maxdash is now 70
* forgot to add supercolor to lua, it is there now
* SPR2_SMSL renamed to SPR2_SSTN (stun)
* any player with a skincolor that's in the super range is set to FF_FULLBRIGHT at state-set time, so no need to keep super players non-fullbright just because they use spin stuff
* Press spin in midair to make the shield flash solid repeatedly and make a number of ding noises.
* When the player with a flashing, dinging shield hits the ground, they are sent off in spinning form at the maximum of 2*abs(momz) VS the 3D hypotenuse of momx, momy, and momz.
* When moving slowly, P_InstaThrust at S_SKIN's maxdash forward, and set momz to S_SKIN's mindash upwards. Plays a tok noise (not thok). Hurts enemies/bosses, busts spikes/monitors/all types of bustable blocks.
* When moving quickly... doesn't do anything yet, but WILL do a slide.
Also, P_DoSpinDash is now renamed to P_DoSpinAbility, and CA_TWINSPIN users can bust all bustable blocks on collision too.
* 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.
* FF_MIDDLESTARTCHANCE - has a 50% chance of starting the spr2 or FF_ANIMATE animation halfway in
* FF_SPR2ENDSTATE - if var1 == S_NULL, don't loop, just stop incrementing the frames. Otherwise, go to the state represented by var1.
The former is just something I did for fun, the latter is something that'll come in handy when porting in new-character-moves.
* radius - sets the player's radius for that skin.
* height - sets the player's normal height for that skin.
* spinheight - sets the player's spinheight for that skin.
* shieldscale - see http://i.imgur.com/BQ5DhKC.png for justification
* If a character select character image is not set, don't iterate every tic - iterate on first image get and then save to the struct.
* A character select screen with only two characters now has special case handling.
* A memory leak in the making has been plugged. (specifically, picname not being Z_Free'd if the loop fails to do so)
* Logic/operation simplification.
Also, some typo corrections and clarity case movements of stuff in other files I've been looking at.
* SF_NOJUMPSPIN - Player's height is full whilst jumping, SPR2_JUMP defaults to SPR2_SPNG instead of SPR2_SPIN, and the player goes into fall frames if they start moving downwards or use their ability.
* PA_JUMP - for jumping (upwards in the case of SF_NOJUMPSPIN.
* SF_NOJUMPDAMAGE - Ala rosy.wad, don't damage enemies, etc when jumping into them.
* SF_STOMPDAMAGE - Just for fun. Ala in Mario, always damage enemies when you land on top of them (your gravity reference, not theirs).
* SF_MARIODAMAGE - SF_NOJUMPDAMAGE|SF_STOMPDAMAGE is reasonably accurate to the Mario games, and might as well be surfaced as such.
Also, a minor change:
* Instead of not spawning the revitem if your SPR2_ is SPR2_DASH, don't spawn it if it's set to 0. This requires the player.dta I uploaded a couple days ago to behave as it was previously.
* Don't get stuck in spindash frames if your maxdash is 0, and don't flash rolling frames if you're on goop.
* SPR2_PEEL, SPR2_SPEE.
* S_PLAY_PEEL, S_PLAY_SUPER_PEEL.
* PA_PEEL.
* Dashmode actually starts charging from runspeed instead of the arbitrarily calculated (normalspeed - 5*FRACUNIT). This just made things easier, honestly, and it's 1 FU of difference compared to the current test case.
- Press spin in midair to stomp directly downwards (losing horizontal momentum), creating a flickering fireball around you.
- No bouncing on enemies, item boxes, etc - just go straight through.
- Hurts other players on touch whilst you're stomping.
- Spawns a bunch of flames around you when you hit the ground.
Also:
- Electric shield's ability now uses different sounds, because I'm picky.
- 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.)
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?
See merge request !85
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.
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.
* Only change texture when stationary or moving down, for additional fidelity to source material. This has zero overhead, and actually might REDUCE lag in some circumstances... my nitpickiness wins again.
* Apply ML_EFFECT1 to it to make it invisible and intangible (removing (FF_SOLID|FF_RENDERALL|FF_CUTLEVEL) from it) from every side except the bottom. Becomes visible and tangible when it's hit once. Might fuck over players in mp, but really our Mario blocks are so high in the air (and we'd need to update Pipe Towers to take advantage anyways) that they're super unlikely to get a kill this way
* Checks for the Brick Block have been switched over to the presence of FF_SHATTERBOTTOM instead of checking for the source linedef's flags every time.
For the object...
* Tag via its angle field
* Number of objects to spawn per tic around it via its z field, if zero then just spawn at center
* Is flipped if given MTF_OBJECTFLIP.
Now there's a linedef type 15!
* Tag is tag of object(s!)
* Object type set via concatenation of frontside textures, MT_PARTICLE is default
* The length of the linedef is the radius the particle is spawned out (zeroed if z field is 0)
* Frontside x offset is speed upwards
* Frontside y offset is number of degrees to turn each tic (zeroed if z field is 0)
* Frontside floor and ceiling heights are the heights in which the particle is bound through some fun mathematics and/or BDSM
Of course, not every story has a happy ending.
* A_ParticleSpawn no longer accepts objects via its var1 because of how specialised it's gotten. Considering it can be set via abuse of actor->cvmem, I don't consider this an issue. Maybe you might disagree.
Linedef type 14 (Bustable block parameter)
* Applied to one of the linedefs of any FOF's control sector
* Concatenation of frontside textures is MT_ object type to spawn, defaults to MT_ROCKCRUMBLE1 if not present
* Sound played when being busted is object type's activesound
* Frontside x offset is spacing (in fracunits) of spawned particles, defaults to 32<<FRACBITS
* Frontside y offset is the fuse of spawned particles in tics, defaults to 3*TICRATE, if set to -1 assume infinite lifetime
* Effect 1/Slope Skew flag makes particles fly out
Linedef type 250 (Mario Block):
* No Climb flag turns it into a brick block (busts when hit from the bottom, player hits their head/fist/whatever, no more upwards momentum)
* Actively impede your acceleration
* Make your animation speeds faster whenever you're moving (to give off that Looney Tunes effect)
The former change is something that was present in the few low-friction circumstances in the classics, and makes low-friction surfaces more of an active challenge. The latter change is just something I did for fun to more clearly communicate that things are different with the physics here.
High friction surfaces DO NOT involve any of this, since it ended up basically cheesing their existing gameplay.
*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...)
*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?

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
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.
See merge request !50
