Caelus API
A coremod and API to provide developers access to elytra flight mechanics through an entity attribute.
Source-provided project description. FreeMinecraftMods keeps creator credit and adds separate compatibility and decision guidance below.
Project overview
Caelus is a small utility mod that abstracts the hardcoded vanilla elytra behavior into a more generic elytra flight attribute and exposes this to mod developers seeking to implement elytra flight for their own mods. All modders have to do is call CaelusApi.getInstance().getFallFlyingAttribute() wherever they want to apply a modifier to the flight attribute. The attribute has a default value of 0, which forbids any elytra flight. Attribute values greater than or equal to 1 will enable elytra flight. The vanilla elytra item has also been changed to use this attribute, keeping its behavior the same as normal. For more information on how to interact with the attribute, see the Minecraft wiki .

FreeMinecraftMods decision guide
This mod is most relevant to players looking for API and Library on NeoForge, Forge, undefined. Treat those labels as discovery hints, then verify the exact file and dependency list on the official project page.
The latest stored update signal is Jul 23, 2025. Older projects can still work well, but they deserve extra compatibility testing before being added to a current world or public server.
What to verify before choosing a file
- Confirm that the file is published by the credited creator on the linked official source.
- Match the Minecraft version exactly instead of relying only on a broad category label.
- Read dependencies, incompatibilities, and changelog notes before updating an existing instance.
- Match the loader or server platform and its required version. Forge and NeoForge are not interchangeable.
- Back up worlds and configuration files before testing the project in a long-term save or public server.
