Frame Skip

Frame skip is a fighting game engine programming technique used to adjust the speed of the game without modifying the frame data. It works by skipping displaying frames at a certain interval. In Skullgirls, for every five frames displayed on screen, one is skipped. The game makes sure skipped frames will still be processed in the game logic and that frame skip cannot make a 1 frame input timing impossible.

The consequence of frame skip is that all listed frame data doesn't exactly match the 'real' speed of the game running in real time. For example, if a move startup is 25 frames, without frame skip this move would come out in 16.667ms (duration of one frame) * 25 frames. But with frame skip, it will be faster than this in real time because of the skipped frames.

Timer Freeze

Throw and hitgrab supers will cause the timer to turn gray, indicating that the game will wait for the super to finish before initiating the time out, but the timer will still be ticking down.

The following will halt the timer completely:

  • Double snap combos
  • Double's level 3
  • The cinematic portion of Valentine's level 3

Canceling / Kara Techniques

Plink Throw

LP and LK don't need to be pressed on the exact same frame to input a throw. Meaning, you may plink LK~LP which will execute a few frames of LK, then throw. This is possible within a 2f window of the first button press.

  • This can be used in a chain where LP can chain to LK to get a faster throw from a LP normal, as opposed to waiting for the LP to recover. One practical way to use this is to do air throw after a j.LP by inputting j.LP j.LK~LP. You may need to delay your super jump cancel, but with the right timing, you can cancel the j.LP into an air throw.
  • It is also possible to plink throw from Parasoul's j.MK and j.2MK as both these normals can chain into j.LK

Kara Airdash

Characters have an airdash lockout period where they need to wait a certain number of frames before they can airdash. You can still use a normal during the lockout, and normals can be canceled into an airdash. This is useful when the normal will alter your trajectory to be lower, improving the frame advantage after the airdash > normal. Peacock can use it with jMK ADC jLP, allowing her to combo off an IAD jLP. Filia can use it with jHK ADC jLK (https://twitter.com/CRYSTALPRlSON/status/1050274569552986117?s=19)

Suki Cancel

Jump startup is 4f and can be canceled by preblock or special / super moves. Preblock can also be canceled into any ground action (except walking/jumping backwards). This will let you block or use attacks out of jump startup. Particularly useful when hitting an assist with a launcher, or jump canceling a backdash.

Plinking Throw Special Moves

Plinking a special move with a LP or LK input with another special that uses a similar motion and a LP+LK input is possible with a 2f window

Alpha Counter Kara Snapback

https://twitter.com/tossle_sg/status/1366234826664251394

If your assist action is QCF + M or H, you can kara cancel your alpha counter assist action into snap back to blow up certain point reversal + assist call tactics. This is because QCF + M/H inputs have a small window where you can cancel into snap back on start up for leniency.

Option Selects

Throw Tech OS Examples

Throw can be masked with another input, but only if you use the kara window for throw inputs (LP~LK or vice versa). Doing LP+LK+button won't tech throws.

  • 1~4LK~LP+MP - Fuzzy block low>high. If they attack with a strike, you will pushblock. If they throw, you will throw tech. If they do nothing, you will throw.
  • 1~4LP+MP~LK - Fuzzy block low>high. If they attack with a strike, you will pushblock. If they throw, you will throw tech. If they do nothing, you will get sLK.
  • 1~4LP+LK~1 - Fuzzy block low>high. If they attack with a strike, you will just block. If they throw, you will throw tech. If they do nothing, you will throw.
  • 1~4LP+HK~MP+LK - Fuzzy block low>high. If they attack with a strike, you will pushblock. If they throw, you will throw tech. If they do nothing, you will get throw + assist.

Preblock OS

[1] [2]

Incoming DJ/Delay Tech

Characters with double jumps only. On incoming, input double jump then delay a throw. You will block meaties, tech throws, or double jump out of delayed attacks (although you will whiff an air throw)

Parry OS (Big Band Only)

Big Band has a variety of strong option selects that utilize his parry.

  • Low/Throw OS - Input 2 ~ 5LP+LK (down, return to neutral, delay throw). This will beat lows, getting you a counterhit throw, or tech a throw attempt. Particularly strong because the nature of the inputs lets you exploit the 17 frame parry window.
  • Left/Right OS - Delay 6 (delay forward input, must be held). This will parry same side mids/highs, and block against crossups. Notably effective against air mixups, since you don't need to worry about high/low. Solid option against characters like Beowulf, who rely on left/rights on incoming setups, and Double, who uses left/right mixups midscreen. Also useful against characters who like to cross-up with their jump-ins, such as Valentine and Annie.
  • Aerial Strike/Throw OS - Input 6 ~ 5LP+LK while in the air. Similar to Low Throw OS, except you parry forwards. This beats strike (parry into counterhit throw) and techs throws. Useful against incoming setups, since players will often try to meaty throw Tympany Drive. Exploits 17 frame parry window like the Low Throw OS.

Inputs

DP (623) Priority

  • 623 motions have priority over 236 motions. An input of 6236+P will read as 623P
  • If you'd like to execute a 236 immediately after holding forward, you can input 4 before you input 236 in order to prevent getting 623.

Charge Moves

  • Charge times are all 35f.
  • "← (charge) → moves can no longer end with a ↗ input, separating special moves from a command to jump forward with a normal."
  • (from Parasoul patch notes) "For 35f after a dash input, ←→←+button and ←→, neutral+button will not perform a special move. This allows dashing normal attacks even after holding a charge. A ←→+button or ←↘+button input can still give a dashing special move. "


Standing 360 Motion

  • "The game will stop you from jumping if it detects you're trying to do a 360 - the jump protection will only come into effect if you start from ← or →."
  • 360 motion inputs now allow 6f between consecutive directions instead of only 3f, and allow a direction to be held for 6f instead of only 5f, making 360s easier for keyboard and Hitbox players.

Negative Edge

If you use negative edge to input reversals (executing motion moves with motion > release of button instead of press) you can prevent getting accidental inputs of other moves.

[3] [4] [5]

Buffers

Reversal buffer after exiting hitstun or waking up from a knockdown:

  • Specials, Supers, and Throws: 4F
  • Heavy Normals: 3F*
  • Medium Normals: 2F*
  • Light Normals: 1F*

Reversal buffer window for exiting blockstun or PBGC

  • Specials, Supers, and Throws: 2F
  • All Normals: 1F*

Normal attacks will not be buffered if holding any up direction.

Some moves have a large buffer for followups such as Beowulf Chair Toss and Squigly Arpeggio.

Button Input Priority

  • In general, the game engine gives lowest priority to normal moves and highest to supers (normals < command normals < 2 button commands < specials < supers).
  • The game engine cannot read multiple inputs from the same button from the same frame, even after reassigning controller buttons or using a macro. Holding a button down effectively locks that button input.
  • When the game engine reads multiple button inputs on the same frame, it registers the command with the highest priority to the game engine.
  • For normal moves, button strength determines priority (LP > LK > MP > MK > HP > HK). For example, pressing LK and HK in the same frame will perform a LK.
  • 2 button commands have priority over a single button command. For example, HK and calling an assist with MP+HK will only call the assist. HK and MK+HP will perform the normal move and call the assist on the same frame. Calling an assist has higher priority than other 2 button commands. LP+LK+MP will register the assist (LK+MP) over the throw (LP+LK) and dash commands (LP+MP).

More Details

  • The game engine reads special and super move motions with distinct individual directions read for at least 1f.
  • Button inputs for a special or super move read in a 4f window, starting at the last required direction for the motion.
  • The game engine registers sequential directions within 4f for a special or super motion. The slowest allowable QCF + P takes 12f.
  • The game engine registers non-sequential directions, or a sequence that require crossing through neutral, within 8f for a special or super motion. The slowest allowable DP + P takes 16f. The slowest allowable 360 + P takes 28f.
  • "The game will buffer dash motions entered immediately after a superjump and perform the dash when the character reaches their minimum airdash height."
  • "The game registers inputs during superflash and passes them to the characters, but the characters will use them to change state only when not frozen. In other words, you can do D,DF,F during the superflash, but you have to hit P after it's over or you won't get a fireball. There's no superflash buffering like in BB or MvC3, it's more like MvC2 or XSF."


Same Frame Interactions

  • Info on trades - https://twitter.com/Skarmand/status/1061752601287450624
  • If two hit grabs hit on the same frame, P2 hits P1
  • If two supers flashes occur on the same frame...
    • P1 will get the super flash first, then on the first frame after P1's flash, P2's super flash will occur. (Example: do Cerebella level 3 on the same frame. This move is active 1st frame after the flash. P1 will make an active hitbox appear, then on the same frame P2's flash will occur)
    • But, only P2 will inflict hitstop on P1. This can be seen by doing two supers on the same frame and having them whiff. P2 will recover (number of inflicted hit stop frames) - 1 frames faster than P1.
      • This can cause some situations where P1 will be stuck in hitstop, P2's super will excecute, then P1's super resumes and the invulnerable frames avoids P2's super, causing P2 to get hit. (video)

Crossups

If you get hit on the same frame that someone does a cross over, you need to block it on the original side. In this image, you can see Filia (P2) has her point cross over to the left, further behind Filia (P1). Most people would expect this needs to be blocked by holding right, but you block this by holding left. This is because the direction you need to hold to perform a block is based off the opponents location before they update their position. So if you hold forward to actually try block this as if it was a cross up hit, you get hit.

  • SG crossupexample 1.png
  • Filia blocked this by holding left, even though the frame it connected hit crossed up.


Bugs

General Bugs

Character Specific Bugs

Peacock
Painwheel
  • Buer vs assists bug: https://youtu.be/gNjWLgSCvU8
  • If Painwheel tags in while under Hatred Install, then the timer will still expire during a combo and the install will run out midcombo. However, if Painwheel DHC's in instead, then the timer retains the normal property and the install will only run out after a combo is over.
  • The frame data for the recovery of Painwheel's tag is not shown in the training mode attack data.
  • Double air throw bug (Possibly Painwheel related): https://twitter.com/CRYSTALPRlSON/status/1117945486718095360
