Kube Utils
by ErrorMikey
Kube Utils, by ErrorMikey, is a KubeJS addon that adds a set of helper functions for scripts that work with levels, fluids and lists.
What it does
Kube Utils extends KubeJS with helper functions and is built on KubeJS, which must be installed alongside it. Every addition is reached through one global object named Ku: level helpers are under Ku.Level, fluid helpers under Ku.Fluids, and so on. The author describes the API as clear, concise and consistent, and says each addition is documented in plain English. The source code is available, and the mod is published for Forge and NeoForge across five release versions, 1.18.2 – 1.21.1.
Level helpers can look up structures and block positions, and they can find a spawn location. Entity helpers can clear space and pick a random location within a bounding box. Fluid helpers return the list of fluids in a namespace and check whether a fluid is empty. List helpers pick random entries from a weighted table. The author notes that only a few helpers exist for less supported areas, and that the set is expected to grow over the mod's life cycle.
The mod is licensed under the GNU Lesser General Public License v3.0 only, so it is open source. Client and server both need it, and the mod is in beta, so the author warns that breaking changes are possible until a stable release.
