Let's Build an Instant Kill Death Ray 

Now I wonder if you could get the arrows from skeletons with power 5 bows or pillagers with piercing crossbows instead, and power this machination even further

dude literally recreated M18A1 Claymore directional anti-personnel mines in minecraft

Who would’ve known those different sized amethyst buds would be so useful

Alternate title: reenacting WWI war crimes with tnt arrow buckshot

should've used projectile protection 4 instead of protection 4 for the final test

I never knew the trapdoor trick existed, thank you cubic! (awesome video)

Now make it activated by a skulk sensor!!!! they’ll never see it coming.

Interesting, I didn't know that arrows stuck in a trapdoor could be primed with momentum like that. I made a similar build years ago, but I had it to where the trapdoor sat a block higher and was timed to open just as the TNT was about to explode, so the arrows would be in free-fall when the TNT exploded. Firing angle was adjusted by adjusting the delay between the TNT dispensers and the trapdoor. I should rebuild it to see how it would fare against armor and such.

Just realized that entities and chunk loading could be a great way to teach particle uncertainty

I really like this style of video. Taking us on the journey instead of showing us the final product. Makes it a bit easier to learn and understand. Good stuff :)

You should name this weapon "The Roaring Dragon" because of the TNT sound it makes when its priming to fire. it will scare any players coming toward it

Could you manually load arrows with a piercing crossbow and will it pierce multiple mobs?

Hey cubicmetre I think the reason for the arrow randomness in your single-shot setup was because the arrow was stopped by a block and then was released again. When I did it, accelerating a perfectly regulated arrow with TNT while it was in the air produced no error, but when even just dropping a perfectly regulated arrow onto a block and then breaking the block, it produced an error.

I used to make TnT arrow cannons using an older version of this idea all the time. Back in 1.7 java beta. You can use an oldschool tnt cannon design, but just place the arrows into a piston instead of a trapdoor, time the ticks to drop the piston on the tick before the TnT explodes and you get an arrow shotgun

Epic. Perhaps by putting the arrows in lazy loaded chunks, we can store more of them.

i like how this went from "funni joke for april fools" to "HOW TO SURVIVE AN APOCALYPSE"

So what you originally intended to make was a rail gun but then it turned into a shotgun... Nice

11:09 a friendly reminder for me to upgrade my armor on the server🙃

I thought about this before, I'm glad someone else that actually understands redstone thought of it too & built it so I wouldn't have to.

American/Canadian content creators: Sometimes crazy stuff (Nileblue) but pretty random and chill. British: More serious and a lot of gamers (same with US a lot) Australians: Absolutely insane

I think the portal thing could work in a different way given a specific set of circumstances. If you lined up the portal so that the arrow would pass through the portal block on a tick (for instance, if the arrow is going 4blocks per tick, have the portal be on a multiple of 4 away) and then somehow loaded all the required chunks at the same time (perhaps with multiple portal contraptions), theoretically the arrow would align with the portal and pass through. Would likely require a lot more setup though.

I love the concept! Keep doing what u do best :)

This is more obliterated by arrow, less shot by arrow

You can keep the arrow alive by bouncing it on a piston so it won't despawn. Then when your ready to fire you can disable the piston, fire tnt, then shoot the arrow. It would save some time from having to setup the arrows.

Give this man a job at NASA

Always a good day when cubic uploads

i like that this video demonstrates a learning process

The minecraft hwacha.... Perfect tech, you just gave me an idea for my castle defense.

I've never found again an off-grid, quasi-unknown player with such redstone skills since Borkon. You do awesome stuff dude, I promptly subbed!

Love the videos! Keep it up!

thx for using my cannon

The only video released today that I trust.

It is in fact possible to get a perfect arrow and tnt alignment. It’s been a while since I developed my own system for this, but: First, you must cancel the x and y momentum of tnt by pushing tnt into walls with pistons (or slime blocks moved by pistons). Without this step the explosion itself is unreliable. Next, you must align the tnt perfectly in between two blocks by pushing with a stair (acts as a vertical slab) at exactly the right time while the tnt is falling. Lastly, you must align the arrow exactly in the middle of two blocks. I think I remember pushing walls for this step, but I think the important thing was that it falls and lands as such: with one side exposed to air, the other somehow wedged inside of a block (it somehow “phases” through when it falls), and the arrow tip resting on two blocks beneath. I don’t remember exactly how I achieved the last step, but I do know perfect arrow alignment is possible.

Aww I really wanted to watch the Projectile protection armor >,

Its basically a railgun shotgun with more spread than games intend shotguns to have.

Amazing video and I love the trapdoor mechanic, how did you discover that one!? This reminds me a lot of your guillotine ;)

"Instant death ray- a fun little contraption"

Thank you for using the trick I discovered

Could make the portal thing work anyway by having 8 portals linked to the same overworld portal

You need more subscribers, both the smartest minecraft physics expert ive ever seen, and a tf2 fan. Amazing.

I open RU-vid and this is the first video I see.... AWESOME!

3:15 "Oh hoohoohoohohoohohohoo oooh boi" - Me 8:15 YEAAAAAAH, Railgun Shotgun has been made!!!

Step ticks are the same as screenshots it’s just a moment in time so when you put it at 4/1 ticks it’s just teleported 4 blocks it’s not actually moving over each block. And the trap door is reducing its momentum because activation of the trap door updates the block data so that’s were the speed is being reduced. You can use block suppression to prevent the momentum from being reduced.

you sir have made a minecraft claymore

would be a good hallway trap have a tripwire or some method of knowing a player is coming in, that starts the priming of the machine, and starts another timer that is callibrated to the approximate distance the intruder could be down the hallway and then fires it. would also be able to put a deactivation method on it as well or simply have cutouts down the hallway for those in the know to hide behind pretty slick man

Woooo!

I once used this idea on a massive scale to help win an mc war to defend my position as the richest person on an economy server

You could probably use a very complex command block setup which uses a raycast so that the hypersonic arrow becomes aware that it has crossed through an ender portal.

Imagine trying to get your stuff back and loading one of the chunks that contained a missed arrow

Pre: I wanna prank my friends lol Post: I made a war weapon

great job

Great video as always man! Just remember that projectile protection is the enchantment to look out for with arrows. Protection does basically nothing.

Just the mere sound is scary

it might not be any significant change but he shouldve tryed it with projectile protection

Designs ultra complex arrow launching machine, still puts melee protection enchantments against projectiles.

Ah a nostalgic pic un the thumbnail lol

8:30 dude invented buckshot in minecraft

THE LORD, HE HAS CAME BACK

Trapdoor arrow glitch has insane potential

Someone needs to invite this man to the SciCraft server for their Hypersonics division

If you have a ton of skeletons all aligned to the same block it makes a machine gun

Awesome i tried to do the same thing after seeing one shotting enderdragon video, To one shot peoples in my corridor, but didnt found a solution that great. Good to know that trapdoor store velocity!

I respect the saxton hale skin

I read this thinking that we’re killing rays

Yet more fun facts to add to my vast knowledge of Minecraft. Thanks as always cubicmeter!

Genuinely a redstone engineer

3:08 Kraftwerk stand ability nice jojo reference bro

We are literally watching someone invent a gun

The correct name for a group of Minecraft Creepers is either a Hiss or a Crater.

Could you not use a large/huge nether portal in the nether layered with air gaps spaced with one air gap in between with a variance after 10 or so portals to catch all the even velocities, that would catch a lot of the shotgun spread and give the arrows a chance to go through the portal?

One idea for this is to have the arrows be made by pillagers with piercing crossbows

I just watched Docm77's newest hermitcraft vid and I was reminded of this

I was just about to go to sleep

finally we got a way to farm the warden

The Arrow Shotgun

Omg that's a brilyate idea

I am now convinced that medium amethyst bud is the coolest item in minecraft

cubicmetre: today i built a fucking railgun that you can even use to surprise your friends!

I'd love to see this tweaked to use as a flak gun for an afk phantom farm / anti-aircraft (elytra) gun

shotgun ballista shotgun ballista stuff it into degroot keep, watch the attackers die instantly

funny little prank to do on my friends, lead them to a very complicated flechette doom shotgun and make it think it dispenses diamonds :D

I quite enjoy the mumbojumbo type contraptions. the "ultimate base defense" type redstone. love it.

Had an idea Maybe you could stack portals in a line so that they all connect to the same one in the overworld and the arrow intersects at least one of them on its pathgoes

When the Elf portal from Botanica had enough

A solution to the problem of the arrows despawning would be to shoot the arrows onto a piston facing upwards and make the piston repeatedly activate. Moving arrows don’t despawn.

*SAXXTON HALEEEEEE!!*

turtle master + proj prot 4 netherite set

So the arrows check if the cross the path of an entity every tick but not if they passed through a portal? Is there a way to make the arrows go through blocks because they have such a high velocity or ?

Make a portable shotgun for flying machines

If these arrows could have piercing 4 that’d be crazy

you seem like you'd be good at programming

shoop da whoop emerged in 2007, which means a solid portion of the viewerbase was not born before it was created

I wish I was smart enough to come up with this sort of stuff lol Also side note, I worked out that for the arrow to be going hypersonic, it would have to go at a minimum speed of 85.75 blocks per tick, mach 5, taking the assumption 1 block is a metre across and 1 tick being 0.05 seconds from what I can find

This will definitely be used in 2b2t

if you theoretically got an arrow to always shoot the exact same spot at the exact same speed every time is it possible that you could place a portal there? because even if its traveling at 200b/t if you placed a portal 200 blocks away would it go through?

Now I know why you didn't play with us on Sipovers's event. That was a cool video!

Nice Saxton hale skin

Arrow shotgun, nice

Yes, i'm a year late, but what if you used a large array of big nether portals? if you had enough large portals, the arrows would inevitably go through, and if you had them linked to the same overworld portal that's much smaller, they would undergo compression and have a concentrated volley on the other side.

You could use harming or healing arrows too
