🏛️ ProtocolExtension extends server possibilities by adding more packets* to the game. 🏳‍🌈 Happy Pride Month!

ProtocolExtension can only be installed as a client on Fabric, and as a server on Paper (and forks). I may add more compatibility in the future but it is not considered currently. The project JAR is both for the server, and the client.

Of course, all players also need to install the ProtocolExtension JAR file (to be able to have the custom packets work), but it doesn't have any dependencies on the client.

(You can make a plugin that kicks players for not using this as a mod, however it's optional to do so - because most plugins I make use this just as a QoL thing, not an essential part of any process)

Older versions of ProtocolExtension are not supported. If you need an update for an older Minecraft version, please request it on the GitHub Issues page - if it's not too different from the latest (in terms of code), I might make a version for it.

ProtocolExtension treats your device safety seriously, and minimizes the provided data as much as possible. The server cannot:

evaluate raw code on your client
log your keyboard or mouse states when used outside of the game
view any HUD elements not created by it

All HUD elements the server makes are automatically removed after you leave the server.

ProtocolExtension has an API to send the custom packets to the clients. A documentation will be available for it soon. To install it, you need to embed the ProtocolExtension jar in your maven.pom/build.gradle as compile-only; more info here.
