Brea Horiz

Event forwarding lets a mod listen for events tied to a specific entity and run the handlers that entity holds, instead of registering and unregistering listeners by hand as entities appear and disappear. Handlers are stored on the entity through an AttachmentType, so each entity keeps its own list and the handlers are looked up when the event fires. The library is aimed at mods that need per-entity event behavior, such as equipment traits, accessory effects or skill systems.

Setup is handled through the GatherEntityDistributeEvent, which should be used to initialize entity event forwarding globally, since data attachments are saved with a Codec and must be reattached after an entity is reloaded, teleported or moved to another dimension. Handlers are added with the EntityEventDistribute method and tagged with a ResourceLocation path, which allows removeMarked to remove every listener under a given path at once. Damage and kill events are forwarded as well. Brea Horiz runs on client and server, and its files are released under the MIT License as open source code.

Public source code and an issue tracker are linked for the project. Brea Horiz has a single NeoForge build, 1.0.0, published on 2024-09-26 for Minecraft 1.21.1, and the project has not been updated since that date.
