Caelus API Mod

Caelus API is an API that makes changes to Elytras to make its functionality available to other items more easily.

Elytras currently works because they have a hard-coded flight functionality, which makes it hard for other modded items to use its functionality without copying some of the game's code or otherwise calling the Elytra code.

To do this, Caleus creates an attribute called CaelusAPI.ELYTRA_FLIGHT, which enables one to access the flight functionality. The functionality has an integer that must be set to above 1 to be enabled; the default is 0.

The vanilla Elytra has also been changed to use this instead. This could but is unlikely to cause issues with other mods.

Caelus is not only for developers, though; it also adds some Quality of life changes to the player experience in the pre-1.16 game versions. Some of the features for players are:

• Turning flight on or off with a key bind (default v)
• Turning flight on or off with a key while in the air (Keybind must be set manually)
• Ability to use a key bind to activate Elytra flight instead of the weird jumping and fireworks movement (Must also be set manually)

Caleus is used by many Elytra mods and even Origins and Thermal Craft.
