* 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.

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
* If you hold down your jump button whilst jumping into it, you no longer immediately use your ability.
* Characters with CA_DOUBLEJUMP and CA2_MULTIABILITY no longer lose track of their jump count.
S_SKIN-provements
I like setting up merge requests before they're ready so I can do code comparisons. Yes, I know it's possible through looking at the branch itself, but merge requests are nicer.
New character abilities:
* CA_TWINSPIN - basically the insta shield but without the invincibility. Think rosy.wad. Destroys spikes, enemies and any bustable blocks (even Knuckles ones!) on contact.
* CA2_MELEE - dash forwards and upwards at S_SKIN's maxdash and mindash respectively, destroys spikes, enemies and any bustable blocks (even Knuckles ones!) on contact.
S_SKIN parameters (all available read-only to Lua):
* "availability" - defines the Unlockable number that has to become unlocked in order to play as the character. (Note: if you don't want this unlockable to show up in the unlockables menu, use type SECRET_NONE in hardcode, or None in SOC. Otherwise, the only other reasonable option is SECRET_HEADER.) Defaults to 0 if not given, or given a number over MAXUNLOCKABLES - which means playable on first boot as usual. The name of the unlockable referred to is set to the character's realname once this is read.
* "radius" - defines the radius of this player under all circumstances as an int, ignoring scale. Defaults to 16. ("radius = 48" means 48*FRACUNIT)
* "height" - defines the height of this player under regular circumstances as an int, ignoring scale. Defaults to 48. ("height = 12" means 12*FRACUNIT)
* "spinheight" - defines the height of this player under spinning/gliding/flying/etc circumstances as an int, ignoring scale. Defaults to 32. ("spinheight = 64" means 64*FRACUNIT)
* "shieldscale" - defines the scale of the shield sprite relative to the player's, as a float. Defaults to 1. ("shieldscale = 1.5" means 3*FRACUNIT/2) - see http://i.imgur.com/BQ5DhKC.png for justification
* "camerascale" - defines the scale of cam_dist and cam_height (the consvars) relative to normal, as a float. Defaults to 1. ("camerascale = 0.5" means FRACUNIT/2)
* "prefoppositecolor" - The sign background colour used when you're using the skin's prefcolor. 0 (the default) means use the Color_Opposite array for all colours.
* "supercolor" - The base colour you flash when super! Irrelevant if you don't have SF_SUPER. See constants below.
* Supports defining sound replacements as both DSNAME and sfx_name formats.
* Default revitem is now MT_NULL instead of MT_THOK to match all characters in SRB2 right now.
* Thanks to MI, all skin flags can be set via "name = 1" or "name = true" or "name = yes" like in 2.0 and before, AS WELL as the current "flags = SF_NAME"
Super colours:
* SKINCOLOR_SUPERSILVER1-5 - "Silver" - done for fun, looks a little bit like Nazo maybe if you're into that kind of thing
* SKINCOLOR_SUPERRED1-5 - "Red" - I originally neglected to do a proper port of Knuckles' super flash to the Reduced Palette. Here, I've corrected that.
* SKINCOLOR_SUPERORANGE1-5 - "Orange" - Ditto, but for Tails. I avoided doing it because Match Super was dying, so why put in the effort? FOR MODDERS!
* SKINCOLOR_SUPERGOLD1-5 - "Gold" - Just a renamed Sonic super to fit the new naming pattern.
* SKINCOLOR_SUPERPERIDOT1-5 - "Peridot" - Nyeheheheheheh.
* SKINCOLOR_SUPERCYAN1-5 - "Cyan" - @Inuyasha wanted me to do enough colours such that you can have a continuous rainbow of super forms.
* SKINCOLOR_SUPERPURPLE1-5 - "Purple" - So... I picked some of my favourite skincolours that were wide enough apart, since these take a while to do.
* SKINCOLOR_SUPERRUST1-5 - "Rust" - One of the first ones I did, because I liked how S3nK Mecha Sonic's super form wasn't yellow. (For Metal Sonic.)
* SKINCOLOR_SUPERTAN1-5 - "Tan" - Geez, I would've loved to call this champagne... [Here's a reference image for the reasoning behind wanting to include this.](http://i.imgur.com/OB18Cls.png)
New frame flags:
* FF_MIDDLESTARTCHANCE - For SPR2: has a 50% chance of starting the animation halfway in. For FF_ANIMATE: has an equal chance of starting on any frame between the frame number and frame number plus var1. For normal frames: Does nothing.
* FF_SPR2ENDSTATE - if var1 == S_NULL and the object is a player, don't loop, just stop incrementing the frames. Otherwise, go to the state represented by var1. Only works for SPR2 animations.
New skin flags:
* 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.
* 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.
* SF_MACHINE - creates explosions whilst dying, creates sparks whilst drowning, different drowning numbers and sounds. Requires new patch.dta.
Character select screen updates:
* All disabled characters - through SOC or unlock (via the above availability parameter) - are outright removed (at least visibly). No awkward gap in scrolling - no hint they were ever there in the first place. Character select selections without valid characters are also hidden.
* Vertical loop - the character select images are visually continuous. No matter where you are in the chain, you'll always see a hint of the character above or below your current selection. (This is as long as you have more than one character on the select screen - otherwise you'll just see that one only.)
* Smooth scrolling - Moto and Prime showed me [a gfy](https://gfycat.com/AshamedEsteemedHammerheadbird) from back during 2.1 development where it was super smooth. I didn't make it as slow as that one, but the smoothness was easy to add and the reason it was removed previously - gaps in the character select leading to varying speeds - is no longer relevant.
* [Gfy of example](https://gfycat.com/RealBrightJay) - Metal Sonic is hidden both to show off it's capable of hiding to 'devs, and to make this safe to show off to the public!
* Fallback for a zero character select screen: just try to pick the first character, whatever it is! Just like when it's forcecharacter...
Character behaviour changes:
* CA2_NONE/CA2_MULTIABILITY no longer forces nojumpspin.
* PA_JUMP - for jumping (only when going upwards in the case of SF_NOJUMPSPIN, otherwise it's PA_FALL).
* Instead of not spawning the revitem if your SPR2_ is SPR2_DASH, don't spawn it if it's set to 0.
* Don't get stuck in spindash frames if your maxdash is 0, and don't flash rolling frames if you're on goop.
* SPR2_SWIM (and S_PLAY_SWIM) for using CA_FLY/SWIM underwater.
* CA_SWIM users no longer forced to run on water.
* Drowning characters fall off the screen slower.
* CA_DASHMODE users can destroy normal spinbust blocks whilst they're dashing.
* CA_DOUBLEJUMP and CA2_MULTIABILITY go together nicer now. Each additional jump (up to the (actionspeed>>fracbits)nd jump) has a jump height closer and closer to zero, much like Kirby games.
* 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)
* 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!
* Default maxdash is now 70
* SPR2_SMSL renamed to SPR2_SSTN (stun)
* player->powers[pw_carry] replaces a bunch of carrying stuff.
* PF_ITEMHANG -> CR_GENERIC
* PF_CARRIED -> CR_PLAYER
* (mo->tracer == MT_TUBEWAYPOINT) -> CR_ZOOMTUBE
* PF_ROPEHANG -> CR_ROPEHANG
* PF_MACESPIN -> CR_MACESPIN
* Rope hangs and zoom tubes are a LOT smoother. http://gfycat.com/BewitchedIcyHuman
* PF_CANCARRY replaces all the terrible checks for flying, and is given and removed properly.
* Turning "god on" in the console whilst super (and devmode is off) will result in... [Well...](http://gfycat.com/DownrightMemorableDwarfrabbit) ~~(if no fun is allowed let me know and i'll put this behind the #DEVELOP define)~~
Multiplayer consvar changes:
* forceskin now takes a string instead of a number, and requires you to have unlocked that skin to set it.
A comprehensive list of all the circumstances characters are available under:
* If they don't have a respective unlockable.
* If they do have a respective unlockable, but you've unlocked it.
* If you're watching somebody's record attack footage.
* If you're forced to by the map you're playing's level header.
* If you're playing multiplayer, and the host or admin (who must have unlocked the character first, or be running a dedicated server) sets the forceskin console variable to that character.
Character-related NiGHTS stuff:
* Skin-based SPR2_ system instead of Sonic's sprites for everybody.
* 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 sprites and colour flashing rules (this will hopefully be replaced by 2.2 with sprites of NiGHTS themselves)
* SPR2_NTRN, SPR2_NSTD, SPR2_NFLT, SPR2_NPAN, SPR2_NPUL, SPR2_NATK, SPR2_NGT0-C, SPR2_DRL0-C. (number of flight directions have been upped for EXTRA SMOOTHNESS)
Non-character-related NiGHTS stuff:
* Rob requested the following link colour sequence at unix time 1470866042, and I had the relevant file open: Emerald, Aqua, Cyan, Blue, Pastel, Purple, Magenta, Rosy, Red, Orange, Gold, Yellow, Peridot
* 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 this way better)
* Drill off into the sky instead of fly up in floating pose (but no noise)
See merge request !32
* 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.
* 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
* Sets the sortscale of the mobj to that of its tracer.
* Basically, Smiles' tails won't clip through shields thanks to this.
* http://gfycat.com/GraveGlassEwe
* Also has support for chains of MF2_LINKDRAW!
