Velocity Exploit on Paper?

In this video we investigate the comments' claims that there exists an arbitrary velocity exploit in minecraft. We look into the code and see if that is true.

I'm back! Also live on Twitch right now, but not with Minecraft. I'm assembling a 3D printer.

[Noxedwin]

I want to see someone present a discussion in real life the way they present in Minecraft.
Randomly pacing, swinging at the air, crouching and jumping, climbing on top of things. Unhinged shit.

You can actually gain insane velocity without hacks by just using tnt minecarts, I managed to fly out over 400k blocks by using 100k tnt minecarts. It's tedious to perform in practice and servers have limits that make it harder to do, but it should still be possible to at least gain the velocity within loaded chunks.

11:04 i like that fact that on the other terminal he used neofetch lmao

[Dfirehail]

For the seed overlay, it would be possible to hide changes by using one of the ignored block types. For example, a nether tunnel filled with vines or mushrooms would go undetected.

Of course it would be possible to add countermeasures against such tactics, but it's worth pointing out flaws in the showcased implementation.

1:25 Yes this does exist! I remember seeing it being used on a bedwars game by some cheaters a while back. They would place tnt down to get a bunch of momentum after it explodes and launches them then they would activate a fly hack of some sort and be able to move super fast through the air without getting lag backed because of the velocity from the tnt.

[supersain]

"we are here to hack, not to cheat" is the best explanation to why people play anarchy servers where you can hack

[specific_protagonist]

Even with an unmodified client, you can give a lot of velocity to arrows with explosions while the arrows are stuck in a block. Doesn't work with snowballs of course.

Waking up to a brand new LiveOverflow video, great start to the morning

[MCgranat]

Ahh, yes.Arch on Live Overflow channel. We did it!

[pigeon_cheesburger]

when you said that the projectile velociy is determined by the player velocity i instantly knew what the exploit does

[araghon]

You could say the exploit works.. on paper

[DrTid]

a fun technical non coding way of getting a high score would be using tnt cannons to launch the snowball
cheapest way would probably be duping tnt into an unloaded chunk until you get enough

[TemporarySolution]

There is a way to reach unlimited speed without explosives. If you fall in a boat there isn't a maximum falling speed (while players, projectiles, falling blocks can't go faster some limit)

[useruser-tiog]

I think the community part could be more of a showcase with your commentary added and a link to a dedicated video. Not all people are as good explainers as you

[Kynatosh]

By lagging the server, we can augment our perceived velocity and we can do these insane half loaded chuncks things and get bedrock in survival for example, it's awesome

[_chappie_]

11:13 that triple nested forloop gave me anxiety.

[Valeryp]

I love how half the comments are like: "just build one of those crazy cannons" xD

[Baezor]

Does anybody know what he did to get a file sidebar on Github? Timestamp 5:55

[Wynadorn]

🤔 So how'd the challenge go? Did anyone get a crazy score?
