Unreal Engine 5 Game Development with C++ Scripting

By: ZHENYU GEORGE LI

Overview of this book

Unreal Engine is one of the most popular and accessible game engines in the industry, creating multiple job opportunities. Owing to C++ scripting's high performance, advanced algorithms, and engineering maintenance, it has become the industry standard for developing commercial games. However, C++ scripting can be overwhelming for anyone without a programming background. Unreal Engine 5 Game Development with C++ Scripting will help you master C++ and get a head start on your game development journey. You’ll start by creating an Unreal Engine C++ project from the shooter template and then move on to building the C++ project and the C++ code inside the Visual Studio editor. You’ll be introduced to the fundamental C++ syntax and essential object-oriented programming concepts. For a holistic understanding of game development, you’ll also uncover various aspects of the game, including character creation, player input and character control, gameplay, collision detection, UI, networking, and packaging a completed multiplayer game. By the end of this book, you’ll be well-equipped to create professional, high-quality games using Unreal Engine 5 with C++, and will have built a solid foundation for more advanced C++ programming and game development technologies.

Working with a basic calculator program

The MYCPP_02 program should have a main() function and an Add() function. The signature and the tasks defined for these two functions are as follows:

  • void Main(): This calls the Add() function to calculate 1 + 2 and 3 + 4 and output the results
  • int Add(int a, int b): This adds up the two integer parameter values, a and b, and returns the calculation result

So, let’s create a new C++ project, name it MyCPP_02, and then add a new main.cpp file.

Then, type in the following code for main.cpp:

#include <iostream>int Add(int a, int b)
{
  return a + b;
}
void main()
{
  std::cout << "My Calculations" << std::endl;
  int result = Add(1, 2);
  std::cout << "Integer addition: 1 + 2 = "
                << result
