This video is kinda obsolete, if you want to see a funnier version there's this video: youtu.be/-EPkAJY9uv8
And here's the wall-less version, which has a more in-depth explanation in the description: youtu.be/XjD4OojWfiQ
Semi-sequel to my last server velocity video? (youtu.be/X4eRb31tRQQ) There's a lot of stuff on this topic I want to talk about but the thoughts don't exist in english yet so you'll have to wait. In the meantime! Look at this silly thing I thought of randomly in my sleep. Yeah I woke up at 3pm so what rare non-3am upload.
The idea is fairly simple: Trick your server position into not updating, move out of the way, and then remove the floor under that position. Since there's no floor it'll just enter freefall and start accumulating fall velocity, while you stand clueless nearby. It won't /actually/ "fall down" since your server position is kind of "locked" in the position it was last it updated, but it still continues to accumulate negative y velocity from being in the air. You do technically see the server position in the top left slowly lowering, but that's a result of the server velocity's offset on it, not it actually "falling"- if that makes any sense.
Actually tricking the position into not updating is rather simple, and it doesn't utilize any sort of lag like I did in the video linked above. In fact! Everything here is completely intentional! Normally your client position just gets copied over to your server position, but this only happens if: you move more than 0.03m from the last position it got updated to, or it's been more than 20 ticks since it last got updated. So first I do a little jump to reset this 20 tick timer(so the TAS would play back in sync), then wait for it to update once more. As soon as it does this though, I move .001m over and open the trapdoor/remove the floor. Since I haven't moved .03m the server position stays positioned over the trapdoor where I started, and since the floor is gone, it enters freefall. Of course I'm still on the floor though since I moved .001m over to another block. I then just sit there while accumulating server velocity. I can't sit here forever since the 20 tick timer will eventually run out and update the server position to over the floor again, but just before that I jump off into the air. This does update the position, but since there's still no floor it continues to fall.
Then just for fun I run into a slime block to convert that huge negative velocity into upwards velocity, and then transfer that over to the client using damage from a fire. Idk if that all made sense I'm still asleep but the other video I linked might have more information.
You can maybe do something similar using hitbox expansion(youtu.be/ScElwg857ck), since server hitboxes stay pretty in check, but it's probably like float perfect to do reasonably idk. Plus you can't press sneak which is fun
