How to use

These are all the functions Hermes provides.

Listening for messages

All you need to do is get the Hermes subsystem and call ListenForMessage, then fill out the channel and message type you want.

You will want to store the MessageHandle and eventually call Unregister Listener to stop receiving messages.

Sending messages

For a receiver to receive a sent message, they must implement the HermesInterface which will call ReceiveUniqueMessage.

Wild Messages

Some cases are small and niche enough that you don't want to bother creating an entire gameplay tag and create a whole new channel. This can happen when you want just two classes to talk together without referencing each other.

This workflow is not really recommended once you go past 2 classes. This is a niche workflow for small use cases.

It works exactly like the regular broadcast and listen nodes, you just fill in the channel with a raw FName.
