Are Multiple Languages Able To Support Their Game Engines?

Yes, multiple programming languages for game development can support game engines. Game engines are typically developed using one primary programming language but often support scripting languages or plugins in other languages. For example:

• Unity Engine: Primarily, unity programming language is C# for development, but it also supports scripting in other languages like JavaScript (UnityScript) and Boo.
• Unreal Engine: Unreal Engine is primarily developed using C++, but it offers support for scripting using Blueprints (a visual scripting language), plugins, and scripting in other languages like Python.
• Godot Engine: Godot Engine is written in C++ and supports scripting using GDScript (a Python-like language) and other languages like C# and VisualScript.
• GameMaker Studio: GameMaker Studio primarily uses its proprietary scripting language, GML (GameMaker Language), but it also supports scripting in other languages like JavaScript.

These examples illustrate that while game engines may have a primary development language, they often allow developers to use multiple languages for scripting, customization, and extending engine functionality.

Which language is used for PUBG?

PlayerUnknown’s Battlegrounds (PUBG), one of the pioneering battle royale games, was meticulously crafted primarily using the C++ programming language. C++ was chosen for its renowned capabilities in delivering high performance and efficiency, which are crucial elements for a game of PUBG’s scale and complexity. Leveraging the robust features and low-level control offered by C++, the development team optimized various aspects of the game, including networking, graphics rendering, and physics simulations, to ensure smooth and immersive gameplay experiences for millions of players worldwide.

Furthermore, PUBG’s foundation lies in Unreal Engine 4, an industry-leading game engine developed using C++. This synergy between the game’s primary programming languages for game development underlying engine facilitated seamless integration. It empowered developers with many tools and resources to bring their creative visions to life. From crafting vast, dynamic environments to implementing intricate gameplay mechanics, the versatility and performance of C++ played a pivotal role in shaping PUBG into the iconic gaming phenomenon it is today.
