How Speedrunners BROKE Slime Blocks

Learn how speedrunners exploit slime blocks to gain extra height in parkour speedruns. How the glitch(es) were discovered, how to perform them, and how a dedicated community uncovered the insane technical details. This is like a slime glitch tutorial and slime glitch history video combined. You don't wanna know how long this has been the focus of my life.

Special thanks to @villager1gaming526, couldn't have made this video without your insane in-depth knowledge!

This history of slime block glitches and tricks includes explanations of ssj, e2e, l2e, e2s2e2sg, and more. That's slab slime jump, edge to edge, ladder to edge, and of course, edge to slime to edge to slme glitch. I'll tell you how to do the slime glitch in Hielke maps, if u listen carefully. That means how to bounce higher off slime, how to do a super slime jump, or whatever you'd like to call it.

Ughghh Minecraft has physics too? Game ruined

I guess you could say that with this glitch, we can take Minecraft parkour to new heights.

This is very intriguing. I wonder how many more repeatable de-sync glitches are out there and are either undiscovered, or not yet well known. Great video! Very informative!

Watched the full video, I am honestly impressed with how such a seemingly simple glitch can be explained further, great job at explaining. It's fantastic how you also used visuals to demonstrate how this and that worked, keep it up! Love ya! 💕

That trick was already known in the German Community since around 2016.
In 2016, I found a map in Jump World, a minigame from Timolia, and it had not only that mechanic, but also other mechanics. Taking damage while on the slime block was merely one of many features of that short but very hard map.
I took those jump and did my own spin on it.
Unfortunately, Timolia removed all maps from prior 2020 (and unreleased maps), so that they can monetize map size.
I had an unreleased map built in 2018/19 that had one very big build in it, the survival inventory in pink with slots filled with what I'm wearing on my skin. That build could now fit within the world border, minus a few blocks, and every map where I used the render distance to hide the tutorial section, or generally the start point of the map where they can choose a path, is no longer possible.

How it works: You need to take damage before the bounce.
The video gives an example that always works without any requirements, but the way I had to learn it, was that hitting the ground before shifting over to the slime block (in the same tick) did the trick. The map had some other things as well, like fire in the air giving you a huge down-pull towards the slime block, which results in the same bounce height.
Damage boosting over a fence was also part of the map, and one of the hardest jumps there was to jump 2 blocks high.
My spin did it a bit different, to make the player rage-quit a lot faster, I used poison instead of fire, as poison has more time between damage ticks.

I was thinking "oh I wonder if this doesn't work with the new update, that would be a shame" but nice to see you mentioned that.
Cool it will still work. Still sad I can't obliterate items using anvils anymore it's by far the most useless but satisfying way.
Good explanation, Interesting topic.

F3+C is new to me and has now changed my life. Great video moose!

[abbyshewrote]

It would be sick to see stuff like this implemented in MCC (or similar tournaments) to diversify skill sets! Thanks for sharing all this info, really cool stuff

[multigrandmarquis]

I cannot believe you brought up parallel universes and weren't joking.

12 seconds into the video and Legitimoose has already affirmed his superiority by managing to speak in sTrAnGe cApS. Only a few legendary individuals possess this power!

I discovered your channel a few years ago because of command block tutorials and I subscribed. Me being from the Hielke Maps community and seeing your videos now is pretty funny, shows how small the world is. Keep it up dude you're awesome.

[itskoder]

Really enjoyed this video! I found it very informative as well as really interesting. I especially liked the little jokes sprinkled throughout the whole thing. They made the whole thing more entertaining.

One nice thing is that bedrock players can do it on crossplay servers and often bedrock players get bounced a lot higher because of lag

[mioki-leaf]

Because of you I learned to do datapacks, use predicates, code in JSON, use execute and all YESTERDAY. I DID A FULL WATCH OVER OF YOUR CHANNEL AND I'M BLAMING YOU FOR THAT

But happy to see a new video

[ThatGeometryDude]

How many of us got the "Paralell Universes" Reference with the SM64 image? (I did)

[lavuy]

it's interesting seeing g how the thought of this trick changed over the years I remeber ur og vid on this topic 2 years ago and at first thought this was a repost lol

[doovid_]

I literally never knew this existed haha. Great video!

[Slackow]

Hmm I knew about the regular damage fence jumping for a long time but never what caused it. That's a really interesting analysis.
