How it works...

In the constructor for our Spotter object, we load one of the basic primitives, a cone, into our Static Mesh Component as a visual representation.

We then rotate the cone so that it resembles a spotlight pointing to the X axis of the actor.

During the Tick function, we get the actor's location and then find a point 200 units away from the actor along its local X axis. We call the parent class implementation of Tick using Super:: to ensure that any other tick functionality is preserved, despite our override.

We convert a local position into a world space position by first acquiring the Actor-to-World transform for the Actor, then using that to transform a vector specifying the position.

The transform is based on the orientation ...
