Myren Eario | Pressing Plates in other Dimensions @myreneario7216 | Uploaded 5 years ago | Updated 3 hours ago
In this video I show that you can press a pressure plate in the overworld, while being in the nether. The pressure plate appears to mainly care about your x,y,z position, and not so much about your dimension.
If you enter a nether portal, you first change your x,y,z position before changing your dimension.
If the chunk in the overworld at your new x,y,z position is loaded, you will be added to the entity list of that chunk.
You will then be in the entity list of an overworld chunk while also being in the nether (at least until the next autosave or something like that)
While you´re in this situation you can press pressure plates in the overworld chunk section you´ve been added to, provided another entity is calling the "onEntityCollided()" function of the pressure plate (here done by an armorstand).
In this situation you can also get effects from overworld beacons while in the nether (which has been discovered by SirRobHiFi youtube.com/watch?v=1SD4RILCyTI )
Also, if you go back into the overworld during this situation then you will be in the entity list of two different overworld chunks at once.
If then one of those chunks unloads you will for some reason lose your hitbox and will be unable to receive packets, which causes some interesting behavior ( see for example this video by test137e29: youtube.com/watch?v=W6nNeRDnaSI&t=410s )
I´m currently trying to figure out which other transdimensional interactions are possible.
The main open question is whether you can use an end gateway portal from the end while you´re in the overworld or the nether. From the code it looks possible to me.
In principle you would just need to leave the end while keeping the chunk in the end at your new x,y,z coordinates loaded, and have an end gateway in that chunk section. Then if you go to the coordinates of the end gateway in the overworld it should teleport you to a new spot in the overworld.
But I might not have thought this entirely through yet, because I just discovered this pressure plate thingy a few hours ago.
But I don´t know anything about end chunk loading. Can you leave the end through an end portal while keeping certain chunks in the end loaded?

![Ghost Blocks [Fixed in 1.9]](https://i.ytimg.com/vi/7bbpTKMFQaE/hqdefault.jpg "Ghost Blocks [Fixed in 1.9]
I found a way to consistently make ghost blocks (blocks, that are there for the client, but not for the server) and the opposite, invisible blocks (blocks, that are there for the server, but not for the client) in 1.8. release. I considered it worth sharing.
And if you watch closely, you can see some very weird piston animations.

My theory on how this thing works (this thing is incorrect, but I´ll leave it here anyways. If you want a correct explanation watch the video Exploiting 1 tick desynchronizations):
When a piston facing upwards gets activated, it tells the block above it, to change to an extending piston head with the same damage value as the block below it (the piston) upon it´s next update. If we use fancy zero tick technology to replace the piston with another piston facing sidewards, before the block above gets updated, the block above the piston will also be a sidewards facing piston head, since it creates a piston head with the same damage value as the piston below it. So this machine creates a sidewards facing sticky piston head moving downwards above the normal piston facing upwards.
The client will just see: There is a sticky piston head retracting downwards. Therefore it will pull the block above the piston head downwards.
The server on the other hand in smarter, and recognizes that the sticky piston head is facing the wrong way and therefore will not pull the block above.
So for the client the blocks above the contraption are pulled down and for the server they aren´t. And these desynchronized blocks are, what we call ghost blocks.")

Earthcomputers Cluster Chunk Finder Program: https://github.com/Earthcomputer/FallingClusterFinderJava/releases
Steps for performing a chunk swap:
1. Activate permaloader and mob switches.
2. Load grid of cluster chunks.
3. Wait for an autosave.
4. All players simultaneously relog. Player at unload platform aligns against cobble wall while relogging.
5. Create invisible chunk. Fly towards beacon tower.
6. Player at unload platform flicks lever and goes through iron trapdoor. Immediately after that the player at the beacon tower place 2 layers of stained glass above the beacon tower.The players should not unnecessarily walk around or move their mouse while doing this.

Also thanks to TFirst for hosting a server on which I could record the video (if I load the cluster chunks on my own computer its so laggy that its unplayable).")

A small obscure technical video, that explains what cluster chunks are, and why you should do all your falling block swaps exactly two chunks away from a clustered chunk.
Generic Method video will come soon.
