Hoshikima

Among the utility items are a Large Bucket that holds more liquid than a standard bucket, which lowers how often a player has to refill, an Ender Pearl Bundle for storing pearls and quick access to them, and a Firework Thruster that extends gliding flight with more precise control in the air. Fabric API is required, and Hoshikima is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license, so it is not open source.

The chain mining feature is inspired by FTB Ultimine and is not available in the vanilla game. It offers four chain modes, where a Single Block Tunnel mines a one-block-wide passage in the direction the player faces, a Double Block Tunnel mines a 2x1 passage, and a Grid Excavation mines a 3x3 tunnel. Holding the chain mining key while turning the mouse wheel moves the player to the next chain mode. Optional Mod Menu support lets the HUD display style be set, and Jade can supply the display style as an alternative.

Hoshikima CM includes an air-skipping function that keeps a chain from stopping when a tunnel crosses empty space, with the number of skippable air blocks configurable per chain. It also checks tool durability before a chain starts, so a tool is not used up while breaking hard blocks. Files are published for Fabric 1.21.5 only, and the environment is client and server.
