Description

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](https://minecraft.wiki/w/Attribute). ## Adding to Your Project: Add the following to your build.gradle file: ``` repositories { maven { name = 'C4's Maven' url = "https://maven.theillusivec4.top/" } } ``` ### Forge ``` dependencies { runtimeOnly "com.illusivesoulworks.caelus:caelus-forge:${version}" compileOnly "com.illusivesoulworks.caelus:caelus-forge:${version}:api" } ``` ### NeoForge ``` dependencies { runtimeOnly "com.illusivesoulworks.caelus:caelus-neoforge:${version}" compileOnly "com.illusivesoulworks.caelus:caelus-neoforge:${version}:api" } ``` Replace ${version} with the version of Caelus that you want to use. ## Support Please report all bugs, issues, and feature requests to the [issue tracker](https://github.com/illusivesoulworks/caelus/issues).
