what happens if two people kill someone or each other simultaneously? (in tf2) 

the logical endpoint of the rocket paradox saga

to be honest this video was really weird to make because it felt like i was writing a report and just compiling scientific evidence. i hope it was still entertaining though!

God Ross Scott was right in his quote, Source engine really is a tower of duct tape.

“4 answers” Impossible, anything that Valve makes cannot have anything above two.

This is some advanced Source spaghetti right here

damn now every one has a valid case on why they died

fun fact: built sentries are managed server side completely (that's the reason the wrangler has a small aimbot), and maybe that's why the sentries destroy each one at the same time

Bots were harmed in the making of this video.

"the first zoo keeper" "the second zoo keeper" "harambe" lol

It's not like something useful in the game, but still interesting for curious ones. Like for bots naming!

2:55 "Sometimes he eats from the left, sometimes the right" *WHOLESOME*

“in tf2” was put at the end of the title, so at first I thought it was about real life

That demo charge behavior is actually useful to know.

"In classic source fashion, I found 4 possible outcomes." God what is wrong with this forsaken engine

"killing you is full time job now" - heavy

“Sentry guns built at the same time will cause them to die together” That’s kind of poetic ngl

"If you look at which sandvich isn't consumed by Gaben" I love this sentence so much

Player's 1 wallet > Player's 2 wallet Gaben: Player 1 wins.

"Everything about this is completely equal" *scouts are flipped from each other*

...if two flares hit a target simultaneously, do both flares crit, neither, or does the flare of lesser priority crit?

This actually explains why my friend always beats me on fair 1v1 melee

Maybe the random ones are because of air drag randomness, kinda like the slight difference between stock pipes and iron bomber pipes

Once, someone killed me, and I got dominated. But I killed him at the same time, which resulted in me getting revenge on a domination that didnt even last for 3 seconds.

One the other note, cave story’s birthday was just yesterday. (For me at least.) I like how you used music for it.

My guess is that the server loops through all players that shoot whenever they shoot, the ones that joined first just happened to be closer to the start of the list of players so their hitscan shots will start and instantly resolve before other players. Because projectiles have to be checked every tick they go into another list, because the player who joined first will resolve his action first he will have his projectile added, then the second player will have his projectile added to the front of the list and they just check everything in the list front to back every tick.

What if we have 2 bots: a scout and a medic bot from opposing teams. What decides which action will be taken first: Uber pop or scout scatter shot?

This teaches me more about physics than any class I've ever had

Don't you mean you found 5 answers? 1245.

I love how quality and interesting this is, the editing has such a nice aesthetic and keeps me watching, i wish I could edit like you

Perfect now I have more to complain about in the game.

By viewing the video again, I found a secret that no one paid attention to: at 3:03, it's not the regular Heavy-exclusive that is used, but the 199$ one with the robot instead of the pot. That's a nice touch there shounic, saying that gaben is fat and rich :D

Summary: First joined: hitscan, taunt, sappers, demo short range charge and manntreads Last joined: most projectiles and long range demo charge Random: sandvich, cleaver and wrap assasin ball All: sentry

1:11 "fire1" and the red pyro's name is "amazon" I love this channel now

What if hitscan weapon and huntsman hit at the same time?

The best part about these videos are the bot names (my personal favorites are at 1:22)

This was a very informational and interesting video! I liked the editing too.

1:19 “fire1” killing the amazon. Interesting choice

5. They both die and their forgotten brother steps in and takes over their company

Simple explosion radiuses were probably among the first code added, along with simple projectile physics, so I think that that may be why stickies are category 1. My theory is that Valve is made up of 3.5 developers (Jeremy made some of the code, but ever since the air blast bug, they stopped trusting potted plants).

I'd guess the reason stickies fall into the hitscan category is because explosions in source are basically just short range hitscan lines being fired out from the point of detonation in every direction, it's really interesting to see that everything that is hitscan based falls neatly into one category and (almost) everything that is entity/projectile based falls into another though

This is great, reminds me of 3kliksphilip but for TF2 instead of CSGO, and I mean that in the best possible way.

*I hear that cave story song in the background of the whole video.*

2:04 blu team be like "what bot?"

Informative! Thanks for figuring this stuff out!

So THATS why I always loose sniper duels. The enemy snipers joined the server first!

I like how you give the bots creative and funny names

0:57 "s1mple" "blyat2" i died

I like the (in tf2) disclaimer in the video.

I don't think the "random" group of weapons are actually random, i think it has to do with how the source engine calculates drag, and unlike the pipes and rockets, the balls and thee guillotine start at a different offset each throw

This is both wasting my life, and answering questions I never new I had, at the same time

A straight to the point video with little to no bullshit. Thank you.

Definitely that there will be a chat as following: “We traded”

your channel is scenarios that dont matter but everyone wants to know the answer

Nice touch to add the (in tf2)

You're a legitimate scientist, I am very impressed.

most thorough explanation I've seen, thx.

What if source is really a platform for observing quantum mechanics? 🤔🤔🤔

Consistency must be a difficult word to spell for Valve employees.

Woah. Fascinating answer to the question we all had at some point

2:36 the scout just a-posing while fading lmao

Very fascinating, thank you!

I can see why sticky dets are in option 1, because it kinda goes along with hitscan in that you press a button and it instantly does a thing

i love how he puts (in tf2) at the end of the title

I will say the first one makes sense for why late joiners seem to stay in the back until more new people

What about Assist Kills? Like when someone is killed by a Heavy pocketed by 2 medics, or a guy getting killed by someone else after getting Mad-Milked by two Scouts at once?

2:56 shounic just made a simulation of whats going on at valve

god I love this type of gaming science stuff, I’m still subbed to pannenkoek for that same reason

Makes sense, the server has a list of players and runs it in order of the list, taking care of the first one who joined each frame. Physics picks a random player cause it takes care of the projectile and not the player actions, it takes care of all the physics at once and not player by player using (what I assume) threads to take care of players by when they've joined and filled the player list

Valve is like apple they revolutionised our everyday living into what it is and also Valve is the OG of 00s revolutionised tech..

3:52 Stickybombs are hitscan confirmed

If you join a server early, play hitscan. If you join a server late, play projectile. If you join a server, just have fun.

I swear these priorities fuck me over every time

pugs are gonna take forever to start now as all the soldier mains wait as long as possible. what have you done

i love the quiet screams of the scout being smacked by two bats at the same time.

mfw i get out of a game with shounic and I suddenly get videos recommended from him, nice.

Those small name jokes on the kill feed are nice

Love the references in the bot’s names lmao

demo charge is something most realistic to happen in real game i guess, nice video

Nice refrance there with the fire and amazon

Dude trying to destroy the universe again with his cursed questions

Lmao the title got cropped out and I didn't read the tf2 part

I thought this was gonna be a joke video but now I'm enlightened.

okay youtube deleted my comment before i could post it so i'll give you the short version of my thoughts: physically simulated projectiles like grenades, cleavers, stunballs, jars, etc. draw some properties (and likely code) from DT_BaseProjectile and DT_BaseGrenade. grenade launchers seemed consistent, but bear in mind that you fired them point blank, where the hitbox of the target is already in contact with the projectile as soon as it spawns. i would suggest doing the same thing with the other projectiles, as well as firing the grenade launcher from a distance. i'm pretty sure you fired the grenades point blank because you know they tumble randomly, but most projectiles do that as well. additionally, i would be interested to know the entity indices of each projectile in all of these tests because the entity with the lowest index usually wins. entity indices could be applied in a seemingly random order if entities are being created or deleted idly around the map or by the server.

Oh boy, i've always wondered what the answer to this quandry would be!

Maybe similar with the sentries, maybe making 2 bots spawn at the same time in spawnpoints right next to eachother would be what you’re looking for. Or maybe im just stupid lmao

Shounic is dominating Harambe

This actually greatly impacts Demo Knight-only servers

Gotta love Gaben clips at the end

So in general, for hitscan you want to join first and for projectile you want to join last.

Your bot names are glorious.

In all my years I had actually a match where this was relevant. A enemy sniper hit me with the conscientious objector while I hit him with the huntsmen at the same time. We both died at the same time.

About the stickybombs. You detonated them after they stuck to the surface, which might change how the source engine views them. I get the feeling you'd get different results of detonated mid-air.

dangit the "downgrade to satellite internet' line got me

I like how he put (in tf2) at the end

One time I was in a match as scout on last in Badwater as the cart was nearing the end. I encountered an engie in an isolated corner of the map and we fought for a bit and during the fight, each made a retreat to try and outplay each other. We rounded the corner and fired at exactly the same time, killing us both. I don't have any record of this event sadly but it will always stick with me.

Gabe aged a couple of years But it looks like he aged 20-30 years

i once got a kill with a sniper riffle after i died, and it gave me the huntsman achievement of killing someone posthumously.

I wasnt paying attention but i got the information as if i payed attention

the bot names are gold.

Instantly recognized the cave story music, ahhhhh good song
