Elevating Game Experiences with Unreal Engine 5 - Second Edition

By: Gonçalo Marques, Devin Sherry, David Pereira, Hammad Fozi

Overview of this book

Immerse yourself in the Unreal game projects with this book, written by four highly experienced industry professionals with many years of combined experience with Unreal Engine. Elevating Game Experiences with Unreal Engine 5 will walk you through the latest version of Unreal Engine by helping you get hands-on with the game creation projects. The book starts with an introduction to the Unreal Editor and key concepts such as actors, blueprints, animations, inheritance, and player input. You'll then move on to the first of three projects, building a dodgeball game, where you'll learn the concepts of line traces, collisions, projectiles, user interface, and sound effects. You’ll also discover how to combine these concepts to showcase your new skills. The second project, a side-scroller game, will help you implement concepts such as animation blending, enemy AI, spawning objects, and collectibles. And finally, you'll cover the key concepts in creating a multiplayer environment as you work on the third project, an FPS game. By the end of this Unreal Engine book, you'll have a broad understanding of how to use the tools that the game engine provides to start building your own games.

Understanding collision events

Let’s say that two objects are colliding with one another. Two things can happen:

  • They overlap each other, as if the other object weren’t there, in which case the Overlap event is called.
  • They collide and prevent each other from continuing their course, in which case the Block event is called.

In the previous chapter, we learned how to change an object’s response to a specific Trace channel. During this process, we learned that an object’s response can be either Block, Overlap, or Ignore.

Now, let’s see what happens in each of these responses during a collision:

  • Block: Two objects will only block each other if both of them have their response to the other object set to Block:
    • Both objects will have their OnHit events called. This event is called whenever two objects block each other’s path at the moment they collide. If one of the objects is simulating physics, that object must have...
