packetevents - 2.4.0 Latest Release

Published by retrooper 4 months ago

New PacketEvents release here!

1.21 Minecraft released a while ago, we are here to publish our first official release that supports it. This release contains various additions and bug fixes. As always, this section is merely a summary of the changes.

This update wouldn't be possible without these contributors ❤️: @booky10, @AbhigyaKrishna, @Bram1903, @MemencioPerez, @IssueDescription, @joshuaprince, @RaynLegends, @ShadowOfHeaven-Me, @dawon, @LeeGodSRC, @cswhite2000

Please note that the declaration of the PacketEvents dependency has changed!

Changes

Gradle build chain reworked (with Kotlin DSL, also have Global Versioning)
Add support for Mojang mapped JARs
Add support for all versions of Adventure v4
Added immutable views on the values within our registries
Reworked PEVersion

ChatMessage_v1_19_1.ChatTypeBoundNetwork replaced with ChatType.Bound
NBT and Component methods added to the ItemStack builder
PacketEvents bStats setting is obsolete as it can be toggled within the configuration file created on the server
PacketWrapper#writeVarInt optimization

Known issues

This PacketEvents update was a rather large one. We acknowledge that it still has a few issues and plan on fixing them in the upcoming patch update.

1. MappedEntity#isRegistered call leads to NullPointerException

Network synched registries are currently being worked on. https://github.com/retrooper/packetevents/pull/866
Completion of this task should lead to the issue being resolved.

2. EntityMetadata issues on 1.20.5+

Some metadata types (eg. spawned wolves) cause issues due to them being implemented incorrectly. Also this, we plan on fixing in the next patch update.

We now have partial support for some new platforms such as Velocity and BungeeCord (Sending packets on proxies is still being worked on)
Our packet wrapper design has shifted from reflection to netty's bytebuffers

Thank you to everyone involved in this update. Finally 2.0.0 is out, from now on we will be releasing minor and patch updates.
Thanks to all the users that helped us test 2.0.0 by using the snapshot versions, you should now update to this release.

packetevents - 1.8.4

Published by retrooper over 2 years ago

CHANGELOG

Added support for 2.0 beta PacketEvents. You can now safely run a plugin shading PacketEvents Beta 2.0.0 and another plugin running 1.8.4 without any issues. There used to be an issue where packets sent by 2.0 would be discarded. (cancelled)
Deprecated PacketEvents#loadAsync and PacketEvents#loadAsyncNewThread. This "feature" was removed in 2.0, so I decided to deprecate it here. It really made no sense having that.

EXAMPLE USAGE

Example for PacketEvents 1.8.4

packetevents - 1.8.3

Published by retrooper over 2 years ago

CHANGELOG

Fixed our injector for 1.7.10 servers.
Just a little note to the 1.7.10 users... Dear developers, please forward this to your users.
Consider updating your server to 1.8.8. There shouldn't be anything holding you guys back from updating your network. Run a 1.8.8 server with ViaVersion & ViaBackwards & ViaRewind to still support 1.7.10 clients if you want. I'm trying to eliminate all 1.7.10 server users. 1.7.10 support might be dropped in future releases in exchange for smaller file size & sustainability. We have to use jars thankfully hosted by funkemunky to support 1.7. If these jars ever get taken down, packetevents would not be able to be built, and we'd abruptly have to end 1.7.10 support.

EXAMPLE USAGE

Example for PacketEvents 1.8.3

packetevents - 1.8.2

Published by retrooper over 2 years ago

CHANGELOG

Added support for new snapshot versions of ProtocolLib.

Background information

Almost 2 weeks ago, I made an issue on ProtocolLib's GitHub repository. I noticed some flaws in their channel pipeline injector. (In monkey words, how to hack into server code and listen to packets) Thankfully a developer called derklaro improved their injector. This leads to better performance for ProtocolLib.

So why would you care?

If you ever came across a ProtocolLib plugin that modified packets, you'd notice packetevents wouldn't get these modifications. This would lead to player velocity modifying ProtocolLib plugins causing issues, especially for anti-cheats. These snapshot builds of ProtocolLib fix this too. ProtocolLib will always process outgoing packets before us.

EXAMPLE USAGE

Example for PacketEvents 1.8.2

packetevents - 1.8.1

Published by retrooper over 2 years ago

CHANGELOG

Fixed update checker.
All builds of packetevents older than v1.8.1 will now have a broken update checker. (if it were enabled) Us now following semantic versioning breaks this. Good side is our current new update-checker will work for the future releases (including 2.0)

EXAMPLE USAGE

Example for packetevents 1.8.1

packetevents - 1.8.0

Published by retrooper over 2 years ago

1.8.0 IS OUT

Happy valentines day ❤️ Oh.. I'm quite late.
I now release PacketEvents v1.8.0. I've been releasing pre-releases for a while. Our last "stable" release was 1.7.9 which was released in November 2020...
If you are a beta-tester of 2.0 PacketEvents, you can ignore this update.
If you were on a pre-release of v1.8.0 packetevents, please update to this.

We now report to bStats how many users run this PacketEvents version. 2.0 releasing is hopefully around the corner, we currently have just under 100 beta testers. Please join my discord if you have interest in learning more about 2.0.

CHANGELOG

Now support 1.18.2
PacketEvents now uses Geyser 2.0 API. This means very old versions of Geyser won't work.
No longer injecting NPCs(fake connections).
WrappedPacketOutEntity(and its subclasses) and WrappedPacketOutEntityHeadRotation constructor accepting rotations now works with normal yaw and pitch as a float. This should hopefully fix bugs with our NPC API rotations breaking.

EXAMPLE USAGE

Example for packetevents-1.8.0

packetevents - 1.8-pre-19

Published by retrooper almost 3 years ago

Please remember this is only a summary of the changes. This update doesn't have many enhancements and focuses on adding 1.18 support and fixing some bugs. I also took time to try add a few optimizations. A pre-release for 2.0 is planned to release soon, it technically is already usable, but might not be as stable on older server versions. Big thanks to the contributors involved in this update, I have to admit that this update definitely wouldn't have been possible without them. Thanks to the donators. As always, thanks to everyone for using packetevents.
And lastly, Merry Christmas! 🎄 🎅

Changelog summary

About the upcoming 2.0 release

As many of you probably know, I have been working on packetevents 2.0 for about a month now.
This is likely the last 1.8 pre-release I'm making before I'll push the first 2.0 pre-release.

Will a stable 1.8 packetevents version ever officially release?
Probably not, there is really no point. The first 2.0 pre-release is planned to release soon, there is no point in quickly putting out 1.8.

Well, then... why are you making this pre-release?
I am just making this pre-release, because I have fixed a few critical bugs.
This is just for the users that want a quick fix to some issues they were encountering as they wait for 2.0 to come out.

Will you still provide support for packetevents 1.8 once 2.0 comes out?
No. As soon as a pre-release for 2.0 comes out, I will not provide support for packetevents 1.8.
But, I will help anyone that needs help migrating from an older version of packetevents to 2.0.

Shading packetevents

If you are shading PacketEvents, you need to soft-depend ProtocolLib, ViaVersion, ProtocolSupport and Geyser-Spigot in your plugin.
Example plugin.yml

name: myplugin
version: 1.0.0
main: me.opdeveloper.myplugin.MainClass
author: myname
softdepend:
  - ProtocolLib
  - ProtocolSupport
  - ViaVersion
  - Geyser-Spigot

API CHANGES

WrappedPacketInCustomPayload#getTag -> WrappedPacketInCustomPayload#getChannelName;
WrappedPacketOutCustomPayload#getTag -> WrappedPacketOutCustomPayload#getChannelName;
WrappedPacketLoginOutCustomPayload#getTag -> WrappedPacketLoginOutCustomPayload#getChannelName;
The channel names in the wrappers above now also contains the namespace on newer server versions, it can be "minecraft:brand" on newer server versions instead of just "brand". Older versions such as 1.8 always had the namespace. I just made the names consistent. This is a sort of breaking change, that is why I didn't end up deprecating getTag, i want you guys to be aware of the breaking change.

IMPORTANT NOTES

I know I may have not added all wrappers/features that might have been suggested. They will be ready when they are ready. We focus on quality and not quantity when it comes to wrappers.

Speed up the process by updating to the pre-releases and reporting bugs! 🙂
