Tumblestone Legends
by CowBerry
Tumblestone Legends adds tumblestone ore to world generation, and the ore is tied to Cobblemon, a required dependency of the mod.
What it does
Tumblestone ore generates through the world, found commonly everywhere. Black Tumblestone clusters appear more often in deeper caves, while Sky Tumblestone clusters appear more often in hills and mountains. Each type comes in cluster, large, medium, small and budding forms, so a single vein can grow from a small cluster into a budding stone.
Generation uses a uniform trapezoidal distribution, which governs how deep and how often each form appears. The mod runs on the client and the server together, and the client side is optional for players who only join a server running it. Cobblemon and Fabric API must be installed on either loader, because the mod does not start without them.
Files are published for Fabric and NeoForge, and the latest builds for both loaders target 1.21.1 only. The author notes that the mod is meant for modpacks and that updates are planned, with a note on support for older versions in its configuration. Builds are released under All rights reserved and are not open source.
Key features
Tumblestone world generation
Tumblestone ore is placed across the overworld, giving players a resource to find while exploring.
Black and Sky variants
Black Tumblestone favors deep caves and Sky Tumblestone favors hills and mountains, so the two types are found in different places.
Cluster, budding and size forms
Each type generates as cluster, large, medium, small and budding tumblestones, giving a range of sizes in the same vein.
Uniform trapezoidal placement
Generation uses a uniform trapezoidal distribution to set how the ore is spread through the world.
