Unreal Engine is one of the most popular game engines on the market, but it’s not just for game development. It’s also used for creating interactive experiences in various fields such as education, healthcare, and entertainment. In this article, we will explore whether Unreal Engine uses C++ and discover its powerful coding capabilities.
Unreal Engine uses C++ under the hood
One of the reasons why Unreal Engine is so powerful is that it’s built on top of C++. This means that when you use Unreal Engine to create your project, you will be writing code in C++. The good news is that if you already know C++, you can start using Unreal Engine right away.
C++ is a popular programming language because of its speed and efficiency. It’s also versatile, which means it can be used for various tasks such as game development, operating systems, and device drivers. When combined with the powerful graphics capabilities of Unreal Engine, C++ can create incredibly fast and efficient 3D applications.
Coding in C++ with Unreal Engine
So what does it look like to code in C++ with Unreal Engine? It’s very similar to other C++ projects you might have worked on in the past. Here are some of the key concepts and features you will need to know:
- Variables
In C++, variables are used to store data values such as integers, floating-point numbers, and strings. To declare a variable in Unreal Engine, you can use the following syntax:
csharp
int count = 0;
- Functions
Functions in C++ are used to organize and reuse code. They take input arguments and return values, which can be used in other parts of your program. To declare a function in Unreal Engine, you can use the following syntax:
csharp
void add(int a, int b) {
int result = a + b;
}
- Classes
Classes in C++ are used to define complex data structures that encapsulate data and behavior. To declare a class in Unreal Engine, you can use the following syntax:
csharp
class Player {
Vector3 position;
Vector3 velocity;
void move(Vector3 direction);
};
- Control Flow Statements
Control flow statements in C++ are used to control the execution of your program. They include if/else statements, loops, and switch cases. To use these statements in Unreal Engine, you can use the same syntax as in other C++ projects.
Powerful coding capabilities
Now that we’ve seen how Unreal Engine uses C++ under the hood, let’s take a look at some of its powerful coding capabilities.
Multithreading
Unreal Engine supports multithreading, which allows you to run multiple pieces of code concurrently. This can be useful for tasks such as rendering graphics and processing physics calculations. Unreal Engine provides several tools to help you manage threads, including the “Threading” window in the editor and the “Threads” node in the Blueprint graph.
Asynchronous Loading
Asynchronous loading is a technique that allows you to load resources such as textures and models while other parts of your program continue to run. This can improve performance by reducing the amount of time spent waiting for resources to load. Unreal Engine provides several tools to help you implement asynchronous loading, including the “Async Loading” window in the editor and the “Load Texture” node in the Blueprint graph.
Dynamic Lighting
Dynamic lighting is a powerful feature of Unreal Engine that allows you to create realistic and dynamic lighting effects in your scenes. This includes features such as global illumination, light probes, and baked lighting. Unreal Engine provides several tools to help you create dynamic lighting effects, including the “Lighting” window in the editor and the “Light Source” node in the Blueprint graph.
Physics Simulation
Unreal Engine includes a powerful physics simulation system that allows you to simulate realistic physics behaviors such as gravity, collisions, and rigidbody dynamics. This can be used to create interactive experiences such as games, simulations, and virtual reality applications. Unreal Engine provides several tools to help you configure and customize the physics simulation, including the “Physics” window in the editor and the “Rigidbody” node in the Blueprint graph.
Cross-Platform Development
Unreal Engine supports cross-platform development, which means you can create applications that run on multiple platforms such as Windows, Mac, iOS, and Android. This is especially useful for game developers who want to reach a wide audience. Unreal Engine provides several tools to help you configure and optimize your application for different platforms, including the “Build Settings” window in the editor and the “Platforms” configuration settings.
Real-life examples
Now that we’ve seen some of the powerful coding capabilities of Unreal Engine let’s look at some real-life examples of how it’s being used in various industries.
Education
Unreal Engine is being used to create interactive educational experiences that engage and teach students in a variety of subjects. For example, Epic Games has partnered with several universities to create courses that use Unreal Engine to teach game development, programming, and animation. These courses have been highly successful and have helped students develop valuable skills that can be applied in a wide range of industries.
Healthcare
Unreal Engine is being used to create realistic simulations for medical training and research. For example, the University of Pennsylvania has used Unreal Engine to create a simulation of a surgical procedure that allows surgeons to practice and improve their skills without risking patient safety. The simulation includes detailed visuals and haptic feedback, which makes it feel like the surgeon is actually performing the procedure on a real patient.
Entertainment
Unreal Engine is being used to create some of the most visually stunning games and movies in the world. For example, Epic Games’ Fortnite, which has over 200 million players, uses Unreal Engine to create its immersive and dynamic game worlds. Similarly, movies such as Avengers: Endgame and The Lion King have used Unreal Engine to create stunning visual effects that have captivated audiences around the world.
Summary
In conclusion, Unreal Engine is a powerful tool for creating interactive experiences in a variety of industries. Its use of C++ under the hood provides developers with a range of advanced programming capabilities, while its cross-platform support and easy-to-use tools make it accessible to a wide range of users. Whether you’re a game developer, educator, or researcher, Unreal Engine has something to offer for everyone looking to create engaging and interactive experiences.
