No Rocket Boosting

Two game rules control the behavior. One disables elytra rocket boosting, so players cannot use firework rockets to boost themselves while flying. The other enables elytra punch bow boosting, where an arrow that hits a player flying with an elytra can push them under certain conditions. With the punch rule set to false, the vanilla behavior of arrows hitting the shooter is kept.

The mod aims to balance elytra flight by removing rocket boosting and adding back punch bow boosting. Its punch behavior is not identical to earlier Minecraft releases, but it tries to feel fairly similar. The mod only works in singleplayer or on servers where it is installed. It is server required and client optional: the server needs it, and a client may add it to remove the arm swing animation when attempting a rocket boost. The source code is public, so the behavior can be read directly. The mod is released under the Creative Commons Attribution Non Commercial 4.0 license and is not open source.
