Question: What game engine does Deep Rock Galactic use?

Answer

Deep Rock Galactic is a cooperative first-person shooter developed by Ghost Ship Games. It runs on the Unreal Engine 4, which is a powerful and widely-used game development platform created by Epic Games.

Unreal Engine 4 (UE4) provides developers with an extensive suite of creation tools for game development, including advanced rendering technology, physics simulation, networking, and more. It supports both C++ programming and visual scripting through Blueprints, which allows developers to create gameplay elements without writing code.

Here's a simple example of spawning an actor in UE4 using C++:

// Include the header file for the actor class you want to spawn
#include "YourActorClass.h"

// Assume this function is being called within an Actor or UObject derived class
void SpawnMyActor()
{
    // Check if we have a valid world context
    UWorld* World = GetWorld();
    if (World)
    {
        // Set the spawn parameters
        FActorSpawnParameters SpawnParams;
        SpawnParams.Owner = this;

        // Define the location and rotation for the new actor
        FVector Location = FVector(0.0f, 0.0f, 0.0f);
        FRotator Rotation = FRotator(0.0f, 0.0f, 0.0f);

        // Spawn the actor in the world
        YourActorClass* NewActor = World->SpawnActor<YourActorClass>(YourActorClass::StaticClass(), Location, Rotation, SpawnParams);
        
        if (NewActor)
        {
            // The actor was successfully spawned
            // Additional logic can be added here
        }
    }
}

In addition to its C++ capabilities, Unreal Engine's Blueprint visual scripting system allows for rapid prototyping and iteration. This enables teams to create complex interactions in their games without extensive programming experience.

The choice of Unreal Engine 4 for Deep Rock Galactic has allowed the developers at Ghost Ship Games to harness the power of the engine to create the game’s unique environments and gameplay mechanics, such as destructible terrain and procedural cave generation.

Using UE4's multiplayer framework, the developers were able to implement robust cooperative multiplayer features in Deep Rock Galactic. This included syncing procedurally generated caves and enemy spawns across players' sessions to ensure a cohesive multiplayer experience.

For those interested in exploring game development within UE4, Epic Games offers comprehensive documentation and tutorials that cover everything from the basics to advanced techniques used in professional game development. This makes it an excellent engine for both indie developers and larger studios.
