Nether Portal teleport range is too large (equivalent to a full block)

This issue relates to MC-93478.

I believe what I’m about to say is relevant to this issue, playing on a realm I created a nether portal, then left that map moving one map over at a diagonal, map is scaled to a 1:8 map or level 3, created another nether portal, stepped in went back through and came out at my first created portal, so this issue won’t allow me to create a nether hub

Can confirm in 21w03a.

Can confirm in 21w05b.

We should be able to downvote issues whose resolution would be unanimously deemed deterimental to the game

yup ^

meanwhile the portal hitbox in bedrock is still full block, just revert this pointless harmfull fix, it benefits no one and only takes away from the game as it renders nether portals next to useless

even as a bedrock player this is kinda dumb.

all this does is either screw over a large amount of technical builds and their respective community on java. and when the entire playerbase (rightfully) cries foul for parity mojang will fix the parity in the most unhelpful way by making the change on bedrock.

also this change truly benifits no one but like 4 people who do not check the cords of the nether portal exit point (you have to always check where your portal will be at with the cords otherwise it can be obstructed and appear at the closest valid portal, most likely at the one you made beforehand)

If anyone needs to mitigate this in PaperMC 1.21.5, to restore full size hitbox before 1.21.6 officially comes out:

1. Download the PaperMC source code with git

2. Place this file at paper-server/patches/features/9999-Revert-broken-nether-portal-hitbox-MC-101556.patch:

1. Generate the patched source code with ./gradlew applyPatches

2. Compile a paperclip jar with ./gradlew createMojmapPaperclipJar

3. The compiled jar will be at paper-server/build/libs/paper-paperclip-1.21.5-R0.1-SNAPSHOT-mojmap.jar
