This Unreal Engine 5.4 video is about Damaging and Destroying Enemies.
We start by adding the Health Changed Delegate logic to the Enemy Actor C++ Class, and then in the Editor, we use the Event called by that Delegate to display the current Health and Destroy the Actor when Health is 0. We then add an On Died Event Dispatcher to the Enemy Base Blueprint, so that we can Bind to it in the Wave Manager, and clean up the Enemies Array.
