Unified Helpers
Class: UnifiedHelpers
Unified Helpers include a ton of custom helper methods to extend functionality in a loader-agnostic way - such as sending network packets, registering internal resource / data packs, injecting into loot tables or adding items to the creative inventory.
All Unified API helper methods are accessed through UnifiedHelpers.HelperName.get().
A helper method of notice is UnifiedHelpers.Platform, which allows you to get the current mod loader, as well as check for specific mods in a cross-loader manner.
