An Analysis Of Human Smash DI and How To Survive Fox's Up Throw Up Air

[@Golden_Magikarp]

"if you move your right hand up and down quickly a lot you might be able to do this, personaly i'm quite good at this..." ROFL

[@bobsaget9894]

Got Karpal tunnel just watching this

[@Prilosac]

Dude. Why don't you have more subs. These videos are amazing. Very complete, very informative, and very digestible. I subscribed and will advocate for your channel when people ask me about concepts you have covered. Great work dude.

[@zabimaru1000]

This is the video I needed when I was starting out. I had vague understanding of SDI, but this simplifies things while also explaining how it works. Time to actually practice some SDI muscle memory on some moves!

[@Exl6243]

I just watched a video that had the term "wank di," and I had no idea what it was. Thanks for the explanation!

[@vaderex1]

Dude, the amount of high quality content you're putting out is insane. Great video again, thank you for making all of these.

[@cillee997]

dude ur a legend, smash di is such an integral part of high level melee, its nuts

[@bongloiny4314]

These videos are by far the best that cover these subject

[@Nahoc]

Great video, incredible that smash players actually use this in real-time. I subbed.

[@Bretaigne]

oh hey

[@jensvide777]

Super good video! You explained everything perfectly! Only thing I would criticize is that the method you used to test the amount of wank SDI-inputs isn't necessarily accurate

[@3rdJan]

This is some good shit, perfectly explained, visuals that help make your point, performing it with a handcam... thank you so much!

[@smugcat6938]

Thank you so much! I was having so much difficulty sdi'ing before this

[@DjaliGoatShow]

I've tried to di out of his up air 1000 times and can't do it, what am I doing wrong.

[@grenncandy123]

Damn son these are pretty solid

[@r0flcopter]

most amazing video ive ever seen

[@MrGameAndToy]

You have 100% earned my sub. Amazing content.

[@danielb7744]

Re 0:54, the effect of ASDI is applied on the first frame of hitstun, not on the last frame of hitlag.

[@RemixSSBM]

+Daniel Baggerman Right, but if you're following Kadano's terminology, the input is "on" the last frame of hitlag, which is what I used here. If i used the term "at" then i would have said the first frame of hitstun.

[@fartonaut2291]

"Take the BPM shown, divide it by 60, and multiply it by 2" OOOOOoooorr, stay with me here... divide it by 30.

[@auroragqp]

Wonderful video! I really appreciate it. You got a new subscriber :3

[@TetraShot]

Dude, your videos are fucking great. Keep it up!

[@chocolope7575]

May PPMD bless you for this video

[@cameroncole858]

How do I make it so 20XX only shows the hitboxes and stuff, like in the jigglypuff up air demonstration

[@MrJ3ly]

wow mate you're a credit to the smash community!/ I think your waveshine combo on peach is totally unrealistic in high level tournament play but the rest of your vids are godlike. Subbed

[@RemixSSBM]

I'm glad you like my videos. Not sure why you don't think waveshine combos are viable outside TAS. I think the exact opposite actually. In TAS, you can SDI so much that fox is way too slow to get a second shine, even on peach/link. Meanwhile in human terms of SDI peach/link are very doable. 9 shines is like 30% damage with 0-2 JC shines, with a very reactable window of 29 frames to react to SDI and line up the shine. I feel it's definitely easier than it looks and probably the only reason people don't do it much yet is because there's no good way to practice vs. SDI. Regardless of if you agree or not, glad you've enjoyed the rest of my videos

[@MrJ3ly]

I meant the humble crouch cancel, best used by sheik and peach - it's pretty rare to see players flawlessly manage to react to the varying distances without the shined escaping behind the shiner.

[@RemixSSBM]

+MrJ3ly You can't crouch cancel mid combo, so all you have to react to is SDI. I'll cover reacting to that in detail in part 2.

[@MrJ3ly]

I thought a crouch cancel was just SDI downwards, which is what I mean.. ferociously hard to react to. Looking forward to the video

[@RemixSSBM]

+MrJ3ly I'll be covering this in depth in part 2, but crouch cancel != SDI down. SDI down doesn't do anything for shine, but if you are able to get a crouch cancel off, you go much less distance and there's very little hitstun

[@antoniobanda9404]

any tips on how to KNOW when to sdi? i can never react and sdi in time ya know? unless i absolutlely KNOW its coming like fox u-throw u-air. help plz

[@RemixSSBM]

Unfortunately, no. You have to read it every time, since the longest hitlag is still shorter than we can react to. With time and practice you'll start to learn the timings for certain things, and a lot of times you can even just guess that you might get hit, even if you may not. When it comes to the timing on something like Fox's uthrow uair, it's really hard. I'd recommend paying close attention to their technique each time they do it, and see if you can catch onto their timing

[@antoniobanda9404]

Remix, thanks

[@SrgntLoveGaming]

Awesome, thanks man. Great content.

[@DoomJoy666]

I've been doing up throw shine turnaround uair so they di into my second hit

[@chasehayesstandup4253]

Can someone give me the tldr on what to do with my hands? Seems like it dosnt require 6 minutes

[@APhishyFish]

Amazing

[@jdog_7599]

For SDI, do you have to hit the joystick all the way? What will happen if it is only hit part way?

[@RemixSSBM]

SDI is analog, so if you move 85% of the way to the edge, you'll get 85% of an SDI. As long as you get out of the dead zone, you'll get at least some movement. I think the dead zone might end at the 50% mark, though I'm not sure on that.

[@sean4850]

so to smash di fox upair as marth, i wait tell i'm in hitlag from the upair then i mash left and slightly up with analog stick and c stick as i'm getting hit or can i do this preemptively to the attack?

[@RemixSSBM]

Mashing the SDI will almost never get you out of Fox's uair. You have to time the input. Marth sometimes only needs a single sideways input on the control stick, so you can either time that input, which is pretty easy, or you can go for the double SDI input as explained in the video, where you press sideways and roll 45 degrees diagonal up (or down) on the next frame. Let me know if you have any more questions about it

[@sean4850]

Remix so i press sideways and roll up or down while im holding c stick to the side for asdi aswell?

[@RemixSSBM]

+sean Yep.

[@sean4850]

+Remix can i preemptively hold c stick to the side and time my input for the control stick sdi?

[@RemixSSBM]

+sean Yep

[@kevinyoutube8365]

For the lightning fast 2 SDI input, you only need to go 18 degrees I think, not a full 45, right? I think wank DI could be argued to be better than the lightning fast method because with wank, you're guaranteed 1.5 input, whereas with lightning fast, you can miss the timing and not get any SDI input. By the way, loving the videos man I'm really learning a lot.

[@RemixSSBM]

Yep, 18 degrees is why its possible to do it double frame perfect or close to it. While wank DI is more consistent, 1.5 SDI isn't enough to escape uair to the side with most characters

[@Hulka10]

amazing video

[@quesote20]

I have this eternal doubt. Does ASDI and SDI sum up? or the distance you can travel with SDI overwrites the ASDI? I heard one time that you couldn't ASDI and SDI to the same side, is that true?

[@RemixSSBM]

They do sum up. I believe SDI moves you 6 units, and ASDI moves you 3 units, so if you press a direction during hitlag, and hold it until after the end of hitlag, you will move 9 units in that direction. That second rule you listed doesn't exist

[@dawudrahman4779]

1) At 4:30 how do u get another smashDI from the diagonally up and right direction? I thought u had to pass one of the cardinal directions as shown at 00:36 unless your control stick is at neutral already. 2) For the first smashDI, when you transfer the stick from neutral to a direction, does this direction have to be a notch of the controller? Or can it be any angle in between?

[@RemixSSBM]

1) The points on the "cardinal" directions you have to pass are not exactly 90 degrees. Check the blue tick marks on the diagram at 0:37. Passing one of those in the indicated direction is what gives you a new smash DI. 2) It can be anywhere on the controller, outside of the deadzone. Doing it to a cardinal notch though allows you to get your first 2 SDI very quickly, and typically you want SDI to be directly cardinal anyways.

[@dawudrahman4779]

Remix / Ok just one more question. Thanks for that response btw it clears up a lot of confusion. Question: For steps 2 and 3 of quarter circle smashDI, do you need to rotate the stick all the way to those 2 notches shown at the end points of the arrows? ( 00:52 ) Or can you just go far enough to pass the blue tick marks shown at 00:37 without reaching all the way to the notch?

[@RemixSSBM]

For TAS, it's actually be better to go exactly to the first angle that smash DI can register (the blue tick), but it's hard for humans to be that precise while maintaining speed, so I just use the notches as touch feedback for when I've moved far enough to reach past the blue tick.

[@dawudrahman4779]

Remix ohh ok that makes a lot of sense thanks. This was a big help

[@scepkile]

Do you have to hold the c-stick on the very last frame of hitlag for ASDI or can you hold it for the duration of the hitlag and it'll still be registered??

[@RemixSSBM]

Yep, doesn't matter what you do before or after. It just checks the C stick position on the last frame (or your control stick, if C stick is neutral)

[@R3ap3RGirL]

zero made a video where he said you should sdi fox upair up.. ?

[@RemixSSBM]

Personally, I think you should DI it to the side. Hungrybox SDI's up, but I think this is a lazy approach, and its success rate has fallen off recently (watch Smash Summit 4) as Fox players have been getting better and better at up throw up air. At most percents the Fox can place the up air deep enough to where you can't SDI up to escape it, so SDI to the side is preferred

[@R3ap3RGirL]

ya that makes sense, ty

[@FP-ih1lu]

You said that by smash di'ing falcon knee, you can live 10% longer than if you didn't. I thought smash di just changed your character position slightly while in hitstun, so I can't see how it makes that big of a difference for surviving hits like this. Does it reduce knockback or something?

[@RemixSSBM]

+Panda Nope, it just changes position. It might be more like 5℅, idk ,never actually checked what the number exactly is

[@Anytime99]

So which method would be the best to avoid fox's up air as puff?

[@RemixSSBM]

if it wasnt clear, press left or right on both sticks and then slide up to diagonally up, while still holding c stick to side. You have to do this really quick. Let me know if you have more questions

[@Anytime99]

ok so essentially a quarter circle up motion. does the location of the stick(s) matter dependent on which direction the fox is facing?

[@RemixSSBM]

I think a 1/8th circle is probably a bit better, but a quarter circle is probably just as good like 95% of the time. While fox's uair comes out slightly farther behind him, don't worry about this when SDI'ing his uair. You still escape with 2.5 SDI regardless of which side you're on. Even if DI'ing in front of fox allows your character to escape with 1.5 SDI, you still need to mix it up or fox can drift into you making the uair connect, so you need to be capable of 2.5 SDI anyways. TL;DR: doesn't matter which way fox is facing

[@Anytime99]

Thanks man!

[@dlm766]

dont play puff lol

[@IssiBang]

asdi counts as smash DI for one frame then u have to control stick smash di in another frame?

[@RemixSSBM]

+IssiBang Ah, sorry if that wasn't clear. When you do the C-stick input doesn't matter, and it doesn't get in the way of control stick SDI. You just have to be holding it by the last frame of hitlag if you want to overwrite the control sticks direction for the ASDI

[@stevensihota1901]

Thank you so much

[@M4Production]

WANK DI breaks the game even further, dude i can't even believe how much hidden moves there are in melee..

[@HoXanna]

does it matter which direction you smash DI the up air? or does both right or left direction work?

[@RemixSSBM]

Assuming the Fox has no aerial drift, they both work. If the Fox realizes you can SDI out of uair, they may start to drift to the side that you last SDI'd to, at which point you should mix it up and SDI the other way, to easily escape the uair. It basically becomes a mixup game, and the fox could even go for single hit uair, in which case SDI up becomes really easy if they mess up, but then if they hit the second hit uair correctly, it doesn't matter what you do. tl;dr: both

[@HoXanna]

Cool! Thanks! Great video

[@TheDanielradio]

Nice!!

[@myboy_]

i can not fucking hit this sdi. im in unclepunch using your method, i get 3 sdi on nearly every upair, but i havent escaped the second hit a single time. im getting seriously frustrated

[@shmurdy]

so is 2nd hit up air timing, spacing, or both?

[@RemixSSBM]

+Minimu5e Both. You have to space the double jump based on puff's percent and DI (DI affects the height) and time the up air after your double jump. Eventually I'll make a video on it, but not sure exactly when.

[@IcicleTFL]

Is there a proper way to practice smash DI on 20XX?

[@RemixSSBM]

In 20XX v3.02 you can set the CPU to uthrow uair you by pressing R+dpadup. Outside of that, most can be done without 20XX. You don't even need to plug in your controller if you're just trying to practice SDI mash speed, for example. You can do a few other things in game like drop a motion sensor bomb near ledge and up-b into it, wait on peach's castle for the bullet bill to come, side-b into flame walls on Falco target test, and maybe a few others... Is there a specific situation you are looking to practice this for?

[@IcicleTFL]

Not in particular, that about answers it. Thanks a bunch!

[@user3lskq3]

i think some of the sdi characteristics are incorrect, or at least contradicts what hax has in his b0xx video

[@RemixSSBM]

What doesn't align with what Hax has in his video? Pretty sure both videos are correct

[@user3lskq3]

So this is the hax b0xx video im talking about kzbin.info/www/bejne/aYOWk39maZJ_d6s Assuming hax is correct, you can't sdi on the first frame, but you can on the last frames, not the other way around like you mentioned at 3:22 And the diagram at 1:35 would be incorrect, since you can't move from diagnal to cardinal to get a sdi. You want to start at a cardinal like you have at 4:13

[@RemixSSBM]

Both videos are correct I try to use Kadano's terminology of "on" and "at" for inputs, but it's kind of confusing no matter how you word it, since Kadano's terminology isn't widely known. Still, since it's the only clear set of definitions I've seen, and since it was defined by Kadano, I go by that. So, for the way Hax explains it, I'd use the word "at" whereas he uses "on". Regardless of how it's explained, both videos are correct, and what's important is that you only can only SDI 1 time less than the number of hitlag frames. The diagram at 1:35 in my video is correct. It doesn't have an optimal angle for the first smash DI input, because I was explaining a basic technique for SDI. You and Hax are right, that a diagonal to cardinal input does not produce SDI, but that's not what I'm showing in that image, I'm showing a diagonal to diagonal input, which does produce SDI. Your first SDI can be any angle, and while starting at a cardinal is preferred, it's more difficult.

[@user3lskq3]

ty for the clarifications :D
