I recreated Touhou's MOST DIFFICULT spell card 

Really cool but not even close to the hardest pattern in the series.

Bro summoning every person with a touhou pfp

One of Touhou's most iconic spell cards* Aside from the title nitpick, job well done.

Bro’s never seen Yumemi throwing the whole Vatican City at you

so many small details youd miss even on your millionth replay appear when slowed down and analyzed, what a unique way to look at bullet patterns!!

Bro is now ready to make his own bullet hell game, you can use a program called Danmakufu

It is not the hardest by any means, but it is one of the most iconic. Nicely well made

There is a project called BulletML(you can see it's old as it's based on xml rather than json 🙃) that is basically DSL for writing patterns.

Im glad you looked at one of Yuyuko's spell cards. Yuyuko is my favorite character in the series!!

this is actually really interesting...

ZUN is an artist.

While this particular spell card is by no means among the hardest ones in the series so far, it's such a beautiful one that it still takes my breath away ever since I first got to encounter it many years ago playing PCB. Plus Border of Life playing along with this spell card sounds so mesmerizing! Recently heard a musician describe his composition process as "close to the science of programming" that seeing you tackle the piece in code made me understand visually what they meant by such an expression. You tackling this work from your field of expertise made me appreciate such a beautiful work of art and design on a deeper level beyond its spectacle too. Thank you so much for this video!

This is super cool, and you’re super underrated! There are much MUCH more difficult spell cards than this though

Ohhh you picked a good one for this project, one of the most beautiful patterns in touhou, and the music in the background just gives you chills as you rush to finish the fight, i absolutely love it, and your recreation was really, really damn good!!

the video ended so abruptly. i was expecting a more in depth look into everything concerning the math, code and design as well as the research put into figuring stuff out D:

You're super underrated! Your mic quality is really good and your script is well written too, I hope you get the recognition you deserve some day!

Reminds me of a time when I was playing around with OpenGL in C/C++, I was recreating (what I think is the most difficult spell card) Pristine Danmaku Hell. It's simple to create, but difficult to survive through! (I should start doing that again someday with Unity instead...)

Well made video Allen. I often found myself wondered about the math involved in the making of some of the spellcards during my playthrough of the 6th game. One pattern that stuck out to me the most for its hypnotic effect was Hong Meiling's spell card "flower sign: Selaginella 9"

This is the type of content I require in my life, my goodness this is awesome!

You did a great job recreating this!

Underated af

Goddamnit, I am in love with this.

Really nice presentation and love for detail! Looking forward to more content like this~

very well made video! I know you're a very new channel, but the quality of your first 2 videos alone look very promising and deserve the boost! I'd love to see more coding / gamedev content from you :D

pretty neat recreation, but there are most definitely plenty of harder spellcards not only are there a good few in the mainline games, there's a certain style of official spinoff game where you challenge individual spellcards one at a time instead of doing the full game in one run, and these games are an absolute treasure trove of difficult spellcards

All this man expressions are on point 😂

Very interesting video! Personally, I'd be interested in more of these Touhou dives, but I'm sure you can also make other content with the level of understanding and passion you have!

Always lovely to see other people try to recreate the patterns on their own. RB as a pattern is quite iconic so it's nice to see it being disassembled like you've shown. Good job on the recreation, It's really close to the original! I am really curious how would you tackle two more patterns from the series, I personally find them more difficult to understand how they work: - Eirin's "Apollo 13" (or any nonspell of Eirin that features a similar pattern) - Kanako's "Divine Virtue of Wind God" Funny enough, I happen to use frame by frame analysis most often to discren what happens. Hopefully I'll see you perform more challenges like that!

That was great! I've tried to recreate a spell card too, in construct2, a long time ago. It was just for fun, but it didn't went that well as it did in your project 😅

Its great how you appreciate beauty of the patterns. Probably you'll be able to code your game too eventually.

> Chooses RB Opinion rejected.

Excellent video my dude 👌

beautiful

"are a perfect blend between chaos and beauty" *insert Junko's spell card* why bro, she is the only one so far violated all of the beauties

While it's far from the hardest spell card, I'm happy to see RB. PCB was the first touhou game i completed, and Yuyuko's big finale is one of my fave moments in the series. Would it be possible to get a looping GIF of the pattern?

One of the most beautiful for sure, but definitely not the hardest. Cool video tho

Popcorn hell Touhou 11 stage 5 boss Konako touhou 10 final boss last spell card XD

Actually wild that this is so under rated, gained a sub from me :D

Reminds me of the ol' Danmakufu days. It's easier to imagine the lasers as really long bullets that just change width when they activate. At least prior to MoF. Curvy lasers from modern era, on the other hand, are probably closer to what is seen here and use sin/cos functions to display their path from the spawner.

Could we get to see the code for those patterns? Would be really cool to create all sorts of other patterns with that

bro never seen divine virtue of wind god

Very interesting style of editing. I like it. I gotta say: It would have been nice if you broke down the sub-pattern, displaying the individual simple patterns combining in order to create the new complex-looking one. Really would have given it a stronger impact on the "Aha Moment". As it is, I have no idea what patterns combined to create this. Speaking of simple rules leading to beautiful results, you gotta check out "The Hidden Mechanic of 「Border of Wave and Particle」" by Virtlux if you haven't. It's about this spiral bullet pattern that looks super complicated and almost random, but at the end of it all, it's really just simple patterns combining together to create a beautiful one. I see you've sneaked in an extra pattern there in the background and, I could be wrong, but that looks like BoWaP or at least some variant of it.

Great video. That was beautiful.

Oh... I though we would be discussing sinus and cosinus but... the video ended before it could take that tangente

Very cool! I'm gonna guess adding "most difficult" was you playing 5D chess to get Touhou players to show up...smart. I've been working on a project that incorporates a lot of Touhou-style attacks as well, and I know just how hard it is to nail these things. Even something as seemingly simple as Mercury Poison has a lot of intricacy and differentiation, if you want to get the timing and movement close to how it is in th06.

I'd love to see Boundary of Life and Death to be recreated this way. You don't even need lasers here

Ahem. "Trembling, Shivering Star" Scarlet Sign "Scarlet Meister" "Fantasy Heaven" New Impossible Request "Seamless Ceiling of Kinkaku-ji" "Fitful Nightmare" ...To name a few.

great job

here before this video blows up (probably)

dayum, this video has a nice quality. Just start making some 10 minutes vids to the algorithim and you are def going big my guy 😉

i make danmaku every day (game developer) and i respect da hustle here. final result looks clean

criminally underrated

this is the cool thing about "patterns" is that they are really just incremental procedures with usually only one variable this is exactly how a lot of dangerous enemies behaved in arcade games as well, do a standard movement procedure and maybe shoot. I find this kind of emergent complexity from simple rules to be way more satisfying than your average "throw billion mechanics in but keep the gameplay loop primitive" AAA games

really cool vid, but I'm curious why you didn't just look at the ECL script of the pattern to see how the game implements it?

amazing

Amazing

"vibrant community" *igyoukyo and kkhta come in*

Disappointed there was no code on the video, but cool

now make bad apple out of it

Really great & beautiful! Can you share the result code? Just for reference, or maybe do you have some keyword to make something like that, so I can try to find it?

Question what did you do to sequence the spawning events? Or did you just call scripts dependant on runtime clock?

Imagine store this into gif and implement a program to lock your phone. Combining them to force youself to complete a spell card to unlock your phone.

I... Have been Summoned...

Maybe look into Danmakufu if you haven't yet

give this guy a PhD in Danmaku Science

Damn, this is great! Touhou patterns are so difficult to replicate, and I've been trying to figure out how they truly work, but your video is amazing in clarifying how they work and the logic behind it! will definitely be taking notes lol

Try making Love Sign: Master Spark from Touhou 8

Been there, done that. I recreated some spellcards on Unity (Namely Aya's Blockade Sign and Yuyuko's Resurrection Butterfly) and it was a ton of fun figuring out how to make the patterns myself. Then I tried doing it with OpenGL and a custom made C physics engine. Let's just say it looked the part but ran horribly... Speaking of OpenGL, what tools did you personally use here?

Very nice, are you gonna recreate more danmaku?

Cool, next time try to recreate the REALLY MOST DIFFICULT spell card.❤❤❤

あなたのビデオはとても興味深いです。

AYO, real nice

Hardest spell card? Not one bit. There are TONS of harder spell cards

woah coolio

Damn

Where is the rest of yhe video?

cool

Neat

I thought you were creating PDH since that's way harder

good video!

i love minusT

this is good

just wait until you play touhou 8

What OCD and too much computers does to a MF....... i am a MF

Now make Inbachi

🤓Erm. Gengetsu timeout anyone?

ma sha Allah bro

This isn't very accurate, the butterfly bullets spawn overlapped and move together before separating at different speeds/accelerations, rather than just having set differences right away. The touhou games have also mostly been reverse engineered, and aside from very exact recreations of many spell cards, you could also always just directly look into the code of the original games themselves.

That's not okina spring final

Code not shared? No git?

"most difficult"

At least he didn't go for BoWaP... 1:15 Never mind.

It's not that hard compared to many other Touhou spell cards, but it comes out of nowhere after the game "ends" and is a survival spell with a long timer.

make a shmup in love2d

not the hardest patternbut cool video. I want to make my own recreations too

no se open ensglish pero esta bueno

hmmm?
