Question: What Language Does Unreal Engine Use?

Answer

Unreal Engine primarily uses C++ for game logic and engine modifications, offering a powerful platform for high-performance game development. Additionally, it provides a visual scripting system called Blueprints, which allows developers to create complex gameplay elements without writing code.

Here's an example of how you might create a simple C++ class in Unreal Engine:

#include "GameFramework/Actor.h" #include "MyCustomActor.generated.h" UCLASS() class MYGAME_API AMyCustomActor : public AActor { GENERATED_BODY() public: // Sets default values for this actor's properties AMyCustomActor(); protected: // Called when the game starts or when spawned virtual void BeginPlay() override; public: // Called every frame virtual void Update(float DeltaTime) override; };

In this example, we define a custom actor class that inherits from AActor, which is a base class provided by Unreal Engine. This custom actor can then be placed in the world and will have its own behavior defined by the functions we choose to implement, such as BeginPlay() and Update().

Blueprints provide a node-based interface for creating game logic graphically. Here's a conceptual example of what you can do with Blueprints:

  1. Creating a Variable: You can create variables like integers, floats, vectors, etc., directly in the Blueprint interface.
  2. Adding Logic: You can drag out nodes from variables and other objects to perform logic operations such as loops, conditionals, and math operations.
  3. Event Handling: You can respond to events including input, collision, and overlap within Blueprints using event nodes.

While Blueprints are designed to be accessible to those without a programming background, they compile down to native machine code, making them highly efficient. Unreal Engine also supports other languages and frameworks through plugins, for example, SkookumScript for scripting and Python for automation tasks.
