This project shows how I made a highlight object function that only shows specific objects. It can be other BPs Pawns or even static meshes. And it doesn't use line trace like all the other tutorials online. Instead, mine will show you all actors within range of the character. You can make it larger or smaller and set specifically what highlights. With this code you could even attach it to say a grenade and make a spotting grenade to show enemies through the walls. It is currently setup to the "F" key. While holding it down if there are items in range set to highlight they will. When you let off they will revert back to normal. This would work great in multiplayer as well since it is in the Player BP. It can be used in 3rd, 1st person, and even VR. Simple to understand code with limitless possibilities.
