[@decino]

Stunning visuals and very informative as always. Pure eye candy.

[@burgerthief5333]

Another great video!

[@christiangottsacker6932]

You guys are doom bros. I hope Peter isnt _jealous_

[@humanbeing_]

The only part I vehemently dislike about his videos.... is that they end! Such great content! (You two should do a nifty collab at some point 8-)

[@adampleyz4688]

Holy Shit! It's *decino*

[@InactiveAcoountSpeltright]

Decino say this about someone else😳

[@generalroasterock8114]

Jesus christ your visual editing is unreal. It's incredible how good these videos look.

[@majamystic256]

i wonder if the visuals are edited into the game space itself or he some kind of greenscreen wad either way the visual editing is amazing and I'm trying to figure it out

[@BananJumper]

Holy shit!

[@SatoshiMatrix1]

explaining the mechanics of the Doom engine visually _WITHIN_ the Doom engine is fucking genuis.

[@muricaneagle666]

967 States huh? Damn, DOOM has like 917 more States than the U.S.

The Great United States of DOOM

Absolutely incredible visual editing and information

[@OldManHan]

Holy cow. This quality is unreal, as usual!

[@nobody-tj1mv]

😇 🐮

[@SuperDragonite2172]

Phenomenal presentation in this video. I only had a rudimentary understanding of how DeHackEd worked before watching. Now it makes a lot more sense. I look forward to your next video.

[@Jamesfrog191]

Excellent video on an interesting topic, only "problem" was that it ended too soon; I could've watched 30 minutes more of this Keep up the good work!

[@mattc7420]

I feel like I've taken smooth Doom for granted after watching this...

[@BiodegradableYTP]

Fascinating stuff, dude. Your visual presentation is immaculate and I have no idea how you do some of this stuff. I love how you utilise Doom's engine itself to such a degree with your presentation. Especially with even building specific assets like at 3:56 to help illustrate a point. That's an extra bit of detail that, while not necessary, is next-level stuff. I see bright things for this channel's future in the DoomTube sphere if you keep up this level of quality and imagination.

[@DoomKid]

It's incredible, this is the highest production value I've pretty much ever seen for DoomTube - the visual aspect is even more in-depth than decino and Coincident's scripted videos, and that's saying something because those guys are god-tier..

[@DinnerForkTongue]

2 years later, I have massive thanks to give to you, borogk. Your explanation of states and how they correlate sprites with actions taken was a *_MASSIVE_* help in getting me to understand how to create monsters in DECORATE and code them to perform the actions I want them to.

[@AutisticYui]

The yt algorithm brought me back and this time I'm staying! Your visuals are always gorgeous and so incredibly helpful for understanding concepts as abstract as these. Phenomenal video.

[@CorporalAdrianShephard]

I love this style, just like “Retro Game Mechanics Explained” best combo (Eye candy + Technical Knowledge = Better learning than school)

[@DoomKid]

I've been playing with DeHackEd for 20 years.. but I NEVER expected to a see a video with this level of production talking about it. You've seriously done an amazing job here borogk - and hopefully this gets more people interested in DeHackEd modding!

[@DoomKid]

2:24 - I'm sure the reason muzzle flash sprites for the weapons are their own states is so only the flame lights up when firing in a dark room, rather than the whole weapon sprite :)

[@DoomKid]

@@borogk I usually get around that damn SSG problem by reducing the "muzzle flash" sprite duration by 1-2 tics for each frame! Basically all my wads have that fix, lol

[@AstorEzequiel]

Woah, that visual editing was amazing! And so was the explanation! Keep going! :D

[@QuintessentialWalrus]

EXCELLENT visuals in this one! The in-game camerawork combined with the motion graphics is stunning and an efficient way of explaining your information. Your vids are always worth the wait!

[@randomname647]

I like the educational value and visual effects of this video. Really nice.

[@2manyghosts]

Keep this quality up and u gonna be on your way to 10K subscribers really soon, I am manifesting it.

[@curlybrace314]

You did an excellent job here presenting a lot of interesting information in a short video!

[@Xenaero]

The visual editing here is fantastic. Good way of explaining it as well.

[@mr-alexander-doom]

Love the recognizable use of BTSX and Ancient Aliens here. Nice to have a visual introduction to the state table like this!

[@linguica]

You don't mention one of the most extraordinary aspects of DeHackEd - that it once again has some actual relevance, as the official Unity port added in DeHackEd support by licensing the reverse engineered implementation from Chocolate Doom.

[@_Firebert]

Visuals on this are superb, great video.

[@yoya8373]

Man I missed you, good to have you back!

[@mapron1]

I totally ok to wait 2 months more for the next video like this.

[@dr00p38]

YES! Welcome back and hope you're doin good :)

[@MittensTea]

Your editing style is so good, well explained video with a super interesting visual story telling. I didn't even know about states and DeHacking until now! Keep it up (:

[@burgerthief5333]

I learnt about state relocations, such as the Plasma rifle audio being modified in Doom Zero. Another great video!

[@nathanbeets8229]

Your practical computer science visualizations are a delight.

[@Contmotore]

What an excellent video! I tried a bit of DeHackEd back in the day and just started playing with it again (WhackEd). This was a very interesting video to watch, thanks!

[@andersdenkend]

Another well presented and funny video! Please keep it up, I want to see more. :D

[@BananJumper]

Finally, new video! You have simply the best animations.

[@LucaEnzo]

Really well made video and very informative. Its understated how much time and effect it takes to deliver the information like you did in this so GG my man

[@TheDeadKorzhik]

You put so much love in your videos. That's really amazing!

[@Sockren]

8k subs and has some of the best editing ive seen

[@FakeMaurice]

Everyone else already said it, but it can't be stated enough. These visuals are AMAZING with a lot of information (with none of it being incorrect). Good Job.

[@carius8125]

I'm so glad i found this channel a few months ago, only having a few subscribers. Your videos are so informative and funny at the same time.

[@TitoffSky88]

Great as always! 👍 Looking forward for another video from you!

[@skyrillexful]

this video is so clean that you could eat on it.

that would make it dirty. (As in dishes, for any idiots out there)

genius presentation of information. Keep them coming.

[@stormcatcher.77]

Wow, great new video! I did not see the dawn of DeHackEd, but now I am even more interested in diving into the distant past of Doom Community. Your presentation is amazing! Looking forward to next one.

Great video & incredible visualizations and animations. Keep up the fantastic work!

I have no idea what any of that meant, but I enjoyed watching it. Looking forward to more from you!

[@Doomsday-zh2zb]

Amazing editing! You can tell alot of information was put into this.

[@Tristan885]

A great video! I've been reversing another game (Killing Time on PC) which makes use (or at least based off) of the Doom Engine and had found the states table and map object definitions in the game executable. When I was attempting to change an action in a state, I was noticing how it was changing nothing and you've exactly explained the reason why with the relocation table.

[@Tristan885]

@@borogk Interesting, I should probably try it again but with using Cheat Engine while I have the game running!

[@Tyle_smalcu]

Yeah, it's always nice to know something more about Doom :D Especially when video is such a well made like yours!

[@doomguy9330]

"DeHacked" What I think of - brutal doom DeHacked

[@0babul0]

Man, this is gonna be great! I remember I made DeHacked mod once (I think it was actually a .BEX) - it changed smoke puff (sprite that displays when you hit something with a pistol/chaingun) to generate rocket launcher explosion - it was pretty fun! Just had to be careful around corners. Hope I will learn a little bit more about that!

[@zombieplasticclock]

I know it's been said a million times already, but god I love the visuals in your videos, they're fantastic. Ended on an interesting note, I do hope you do a follow-up video on Doom modding. I've wanted to get into it, but never really knew where to start

ty for captioning

[@WSADKO]

Dude! It's fucking amazing :D Grade A stuff right here

[@beanstable]

Goddamn this was awesome

[@ribosome4054]

damn, i never realised that it was this difficult. I always thought that coding back then was really simple as i am very used to modern game engines. Turns out coding was a nightmare back then, and a salute to these programmers who gave us all of this interesting insights into the code just so we can experience what it was really like to code all of this. Absolutely beautiful.

[@xX_Lol6_Xx]

I remember the first dehacked I made, I made my weapons a lot more OP, but also made the cyberdemon and mastermind shoot revenant missiles, very crazy

[@DoomKid]

Oh, I almost forgot! There's actually a more up-to-date version of DeHackEd for DOS here - www.doomworld.com/forum/topic/117871/ - It's almost the same as the idgames one, but it now has proper Final Doom support (and a few other minor fixes). Maybe it's worth linking in the description?
