My streak for Minecraft-related projects goes on. This time, I wrote a full-on mod with a mod loader, Fabric. This mod limits how fast a player is able to fly with an elytra. The max speed can be configured inside a configuration file. There are two sides where my mod changes behavior: On the server-side, it caps the player's velocity. On the client-side, it changes the prediction logic of elytra flight based on the max speed of the server. Without changing the client-side predictions, the player may experience rubberbanding. It enables multiplayer servers to nerf the elytra and reduce chunk-loading lag. A lightweight mod that will also be used for my own Minecraft server!
