Catenaty is a datapack that adds decorative chains and ropes, also known as catenaries, to Minecraft. You can place a catenary using custom Firework Rocket items, which lets you place the anchor points off the block grid for extra customisation.
Illuminating a cave with hanging lanterns.
Catenary items have a custom data component, which defines what kind of catenary will be placed. This data can be fully customised by map makers, but there's also a few presets available for survival players.
Several variants of chains.
Customisable text spellings.
The newest version of Catenary also allows you to ride catenaries as a zipline! To use this feature, right-click one of the anchor points with a Bow. These ziplines have realistic movement mechanics, so be careful not to get stuck in the middle of a rope!
