Quick Start

With the following steps, we can quickly define and use an event.

Define an Event#

To create an event, we need to define a subclass based on UDidaEvent, which can be a C++ class or a blueprint class.

Broadcast the Event#

In the blueprint, you can call the DidaInvokeEvent node to trigger the event.

Listen to the Event#

In an Actor, you can use DidaEventListenerComponent to listen for events.

Set the Component’s properties to configure the events you want to listen to.

Use the Delegate on the Component to define the logic that will run when the event is received.

🎉 Following the steps above, we have implemented a feature:

When pressing a key, the character object outputs a log message.
