If you for some reason really cannot update now, here is a temporary solution to the problem in form of a plugin: hangar.papermc.io/kennytv/Ex… There is a number of plugins claiming to fix this already, but they either don't properly catch the exploit or also impact normal users.

❕If you are a plugin developer and are using vanilla internals in any your plugins, please test them on the following server jar to make sure they are compatible with future versions of Paper: github.com/PaperMC/testing/r… Also see forums.papermc.io/threads/pa… for more information.

Release 2024-03-21: Paper without CB package relocation · PaperMC/testing

Do not run this jar in production; copy it to another setup. Don't worry that it is Mojang mapped, plugins jars will automatically be remapped. Only the CB package relocation cannot be handled ...

These changes are still some time away, but doing any required updates as soon as possible would be ideal. In the future, this means that two major, unnecessary barriers to using internals will be gone, since we recognize that sometimes you can't achieve *everything* with API.

1.19 #92 adds API to add custom chat completions, useful for adding stuff like emoji completions! #95 adds new collision APIs to check for in a world, as well as whether an entity would collide with boats, the worldborder, or any block at another location #ThisWeekInPaper
Graphic divided into 3 sections. The first section is titled "RegionAccessor#hasCollisionsIn", with the subtitle "You give: The box". Below that you can see a minecraft tree, overlayed over it is a red box. Besides the tree is a green box. The second segment titled "Entity#collidesAt" with the subtitle "You give: The location" shows a creeper overlayed over a tree inside a red box, and a creeper not touching the tree inside a green box. The third segment is titled "Entity#wouldCollideUsing" with the subtitle "You give: the box". It shows the same as the second segment, except now the creeper and the boxes are stretched/pushed.

Vehicle Teleportation: You can now teleport entities that have passengers by setting the ignorePassengers flag to true on the teleport method. Note that you cannot teleport entities with passengers between worlds.
Code example with the following code: //Vehicle Teleportation entity.teleport( location, true // Teleport the entity and its passengers );

ALT Code example with the following code: //Vehicle Teleportation entity.teleport( location, true // Teleport the entity and its passengers );

Smooth Player Rotation Setting: You can now smoothly change the player's rotation without modifying their velocity with Player#setRotation. You can also force the player to look at a certain location/entity using Player#lookAt.
Code example with the following code: //Smooth Player Rotation Setting player.lookAt( location, LookAnchor.EYES // Make the player's eyes face the location ); player.lookAt(entity, LookAnchor.EYES, // Make the player's eyes face LookAnchor.EYES // the entity's eyes );

ALT Code example with the following code: //Smooth Player Rotation Setting player.lookAt( location, LookAnchor.EYES // Make the player's eyes face the location ); player.lookAt(entity, LookAnchor.EYES, // Make the player's eyes face LookAnchor.EYES // the entity's eyes );
