How to Use

1. Set up your message structure:

2. Create a function to send the message:

In your class, create a function to send the message and add a gameplay tag representing the channel:

Note: You can also broadcast messages directly from Blueprint using the BroadcastMessage node.

3. Test it in Blueprint:

Create a child actor class from MyActor C++ class and another actor that doesn't necessarily need to inherit from MyActor.

In Actor01 Blueprint, create a sample message to send on begin play.

In Actor02 Blueprint, specify a channel and select the relevant message structure to receive the message from Actor01.

4. Define gameplay tags and message structures:

Define gameplay tags for sending or receiving messages on specific channels.

Select the structure containing your message data (e.g., SampleMessage).

5. Test the setup:

After placing both actors in the level, the message sent from Actor01 should be displayed on Actor02 when the game begins.

Enjoy seamless communication between gameplay objects using the Gameplay Message Router!
