Overview of this book

Game development can be both a creatively fulfilling hobby and a full-time career path. It's also an exciting way to improve your C++ skills and apply them in engaging and challenging projects. Game Development Projects with Unreal Engine starts with the basic skills you'll need to get started as a game developer. The fundamentals of game design will be explained clearly and demonstrated practically with realistic exercises. You’ll then apply what you’ve learned with challenging activities. 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. In this project, you'll explore line traces, collisions, projectiles, user interface, and sound effects, combining these concepts to showcase your new skills. You'll then move on to the second project; a side-scroller game, where you'll implement concepts including animation blending, enemy AI, spawning objects, and collectibles. The final project is an FPS game, where you will cover the key concepts behind creating a multiplayer environment. By the end of this Unreal Engine 4 game development book, you'll have the confidence and knowledge to get started on your own creative UE4 projects and bring your ideas to life.

Preface

Visualizing the Line Trace

When creating new logic that makes use of Line Traces, it is very useful to actually visualize the Line Trace while it's being executed, which is something that the Line Trace function doesn't allow you to do. In order to do that, we must use a set of helper debug functions that can draw objects dynamically at runtime, such as lines, cubes, spheres, and so on.

Let's then add a visualization of our Line Trace. The first thing we must do in order to use the debug functions is to add the following include below our last include line:

#include "DrawDebugHelpers.h"

We will want to call the DrawDebugLine function in order to visualize the Line Trace, which needs the following inputs, very similar to the ones received by the Line Trace function:

  1. The current World, which we will supply with the GetWorld function
  2. The Start and End points of the line, which will be the same as the LineTraceSingleByChannel function...
