Circular Blocks
Circular Blocks adds cylinders, quarter cylinders and angled pipes in several sizes, giving builders rounded shapes that vanilla blocks lack.
What it does
The mod adds circular block shapes in a set of sizes. Cylinders come in 1x1, 2x2 and 3x3 footprints, quarter cylinders are offered in the 1x1 size, and angled pipes come in 1x1, 1x2, 1x3, 1x4 and 1x5 lengths, each with rotated variants so a pipe can be placed along different axes. The author describes the collection as a proof of concept that will be extended later.
The mod is built for Forge and runs on the client and on the server, so both need it for the blocks to work in a world. The code is open source under the MIT License. Files exist for six game versions, 1.20.1 – 1.20.6, and the latest Forge file, 0.2.0, targets 1.20.6 and sits on the alpha channel. Public links to the source code and the issue tracker are provided.
The author notes that block and item names are not yet translated, and that lighting on the quarter cylinders matches vanilla quarter cylinders when they are placed next to each other. The 0.2.0 release introduced a solid block made as a cylinder, and more shapes are planned.
Key features
Cylinders in three sizes
Cylinders are available as 1x1, 2x2 and 3x3 blocks for round columns and pillars.
Quarter cylinders
Quarter cylinders in the 1x1 size give rounded corners and curved walls, with lighting that matches vanilla quarter blocks.
Angled pipes with rotation
Angled pipes run from 1x1 up to 1x5, with rotated variants for bends along different directions.
Solid cylinder block
Version 0.2.0 added a solid block shaped as a cylinder, the first block of its kind in the set.
