[TAS] Doom 2 UV-Speed in  

dude's got insane times in like every speedrun!

He also plays Half-life and other games beating the sh*t out of them.

Only Rodd Toggers ever managed to beat him.

pretty sure TAS is cheating!

(In a thick British accent)"This distinguished sort of gentleman is fashionably graceful at this field of first person shooting"

new best record !

Honestly it took me until I was getting close to the end until I believed it myself! I didn't know when to start really hoping for it.

DID THE IMP AGREE ON THAT???!!!1

@@aleksandrk2814 i guess not, rip.

I was pretty happy with how that turned out even though I'm not sure it really saves any time since you can just rocket off of the wall anyway, but the imp does help me gather some momentum and slingshot over to the rockets before the key grab. But the important part is it looks cool :) Thanks shock, I'm so happy it's done!

Have you ever seen Red Recluse's run of Tarachillax Map 6? Lol

Thank you :) The difference between ZM and I is that he could likely TAS like this if he dedicated the time to it, but I don't think I could play like him if you gave me a hundred years to practice, haha.

Comments like this seriously make my day. Thank you so much for watching and for the kind words.

I didn't realise how close it was until after this demo was completed, I would have loved to be faster than that run! I can settle for being one second away though :)

Even better: rocket jump off of the Lost Soul, followed immediately by a mid-air wallrun against the Cacodemon. :) Thank you!

@@almostmatt1tas how do you figure this out even whoa!

@@Allstin I believe it’s been theorized a few times and someone managed to pull it off once, although I don’t know who and I’m not sure if the demo is easily accessible. Lots of crazy stuff going on here for sure haha

As Rocky said I'm not the one to have come up with the idea, there are people far smarter than me that have been thinking about the route for this game for a long time! There are two instances I'm aware of where it kinda-sorta-almost happened, but this demo is the first to successfully fully pull it off. - Another TASer, xepop, came very close to managing the jump in an abandoned full game TAS. They apparently made the distance, got the right angle, but *barely* didn't manage to land on the ledge at the other side. Without having seen the demo I'm assuming that they briefly touched the platform but had too much momentum in a direction away from it, so then they were thrown off it on the next frame. - Another TASer, Vita, managed the trick but using a custom edited map and running with turbo speeds. Turbo speed allows you to get the speed I got with a rocket boost simply by running, and by editing the map they could manually place a cacodemon in the exact right spot for them to wallrun against it. In this way they proved to me that, ignoring the uncomfortable fact that you need to mess with manipulating the position of multiple enemies while timing your firing and running correctly, it WAS theoretically possible to actually pull of.

Thanks! Purely building might squeeze out more time, but man does it leave me intensely jealous of your build times, haha

sory for spam coment :(

Thank you very much! :)

Interestingly, in a TAS setting diagonally running actually significantly increases your likelihood of finding input combinations that can result in an instant glide. Being able to define a forward movement value, a sideways movement value and turning value gives you significantly more potential locations to end up in when compared to just moving straight forward and turning. Most of the time, including this particular instance, TASes can get glides efficient enough to actually gain speed as you do them. :) Totally different situation non-TAS, of course!

Rocket splash damage isn't rng based - it's just the distance of the target and the explosion, meaning you can get both rockets to deal maximum splash damage to the icon, killing it in two rockets.

@@rocky47251 thx Rocky!

Thanks! And yeah, what Rocky said :) I first saw it in Zero Masters Nightmare TAS. I believe he was the first to actually do it, but termrork was apparently the one to theorise using Lost Souls to autoaim rockets to the hole in the Icon of Sin.

That trick is one of the most amazing things I've seen in Doom, and I watch a lot of TAS runs.

One of the coolest parts was on icon of sin, using the lost souls to aim the rockets was unbelievable

Thanks! :) It's possible to get into a very precise position and press a switch from the left side of it, from further away than you're normally able to press a switch. On the last frame of map 7, the switch I'm facing isn't actually the one I press, it's the one facing to the right. It's possible non-TAS but a TAS is able to do it instantly. The trick is also done in 4 other maps. In map 30, I manipulate luck so that the Icon Of Sin spawns a Pain Elemental. When they then fire a Lost Soul towards me, I shoot a rocket towards the Lost Soul. If I do it right, autoaim kicks in and angles the rocket very slightly upwards towards the exposed brain of the IOS while still missing the Lost Soul.

Thank you! :) With the currently known strategies and routes I think mid/high 9:3x would be possible, anything lower than 9:35 would start to quite surprise me. The biggest question for me is how much faster the map 29 jump can be done, I honestly have no idea, but it can absolutely be done faster and I believe that that's the biggest variable in estimating a truly optimal time.

Thanks! :)

I'm writing up a tasvideos.org submission post which will go into more detail about every trick and I'll link that when it is done, but here's an explanation for just the map 18 clip, the one around 6:23. The trick takes advantage of two facts of movement in the Doom engine: - Running into 'things' including enemies allows you to keep and even gather additional momentum (but generally only up to the regular speed limit of roughly 23 units/frame). Because "momentum" and "distance travelled" are distinct things, it's possible to run against an enemy and even though your location is not changing, your momentum value remains high. (Another clear example of this type of thing is momentum preservation tricks against opening doors.) - Running into diagonal walls is somewhat of a dice roll in that the majority of the time your momentum will just die, but very occasionally and in ideal circumstances, the engine will freak out, make a mathematical error and give you much more momentum. In a TAS, we have the control to ensure the outcome is good, but it's quite precise and hard to do well even with tools. For this clip, both happen at once. I wedge myself between the enemy and the diagonal wall just in front of the door. Running at the correct angle against the diagonal wall in the right way gives me much more momentum, but since the enemy is blocking me I don't actually move and crash into a door or wall and lose my speed, and since I'm running into a 'thing', I simply gain much more momentum. The player is, as you say, 32 units wide but the door is also 8 units wide, meaning if I got perfectly close to the door when I began gaining massive momentum I would need a momentum value of 40 units/frame. Several problems arise: if I get too close to the door during the setup, I actually move past the hitbox of the enemy and all the above stuff fails, and so I needed to optimise how close I could get to the door while still being in contact with the enemy, which of course changed its random behaviour and movement patters, AND it's slightly moving while I'm gathering momentum, so the solution to keep the enemy in place was actually to shoot and kill it but that also needed to be timed perfectly. I ended up getting 'stuck' about 3.8 units away from the door and managed to move 46.2 units in one frame, so this only worked by about 2.4 units. As nuts as that all is it's actually possible non-TAS! It basically involves just running into roughly the right spot and hoping it just sorts itself out, which IMO makes it even cooler :) Check this out: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-L5OFfJbClxM.html

@@almostmatt1tas Wow, very cool! If this doesn't make Moons, I don't know what will :)

Pretty much, but because the other wall is also diagonal it requires a very precise position to get into while building momentum. The trick was found by Zero Master, who has a great explanation of it in his video showcasing the trick. Here’s the link ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fI-Skyu1jyI.html
