Game Engines - Elevating The World Of Creating Games!

Game Engines

Gaming is not anymore a mere hobby. It’s a passion that has created an entire clan for itself. So, let’s look behind the curtains and see where does it all come from, or to be precise where does it all has been created from!


What is a Game Engine?

Game Engine is a software development environment that helps in building a video game. It is an amalgamation of various components, providing features that are useful in creating games. Game Engine is one such already created fixed-base for the developers so that they can completely focus upon the further building and enhancement of the game. The game engine saves the developers time by offering them with multiple preset modules, tools, effects and libraries.


Why use a Game Engine?

  • Helpful to 3D artists in importing their assets, created for different programs such as Autodesk 3Ds, materials created for the models, working upon the lights to give a more believable look and feel.

  • Versatile enough to build games for all platforms - mobiles, websites, Playstations and personal computer.

  • Renders everything from 2D/3D graphics, sound, animation, to physics of the game, memory management and video for cinematic support.


6 Major Elements of How the Game Engine Functions:


  1. Graphics

The most popular and powerful game engines let the developers create 3D assets in any other rendering program that they will choose and then later on import it to their selected game engine.


  1. Sounds

The developer can design the sound of his choice from the scratch, right from the composition of the music, different sound effects to voice editing and the post-production work. Also, one can integrate the sound natively or from the third party, elevating one’s scope of focusing on composition and sprucing up the sound with some creativity.


  1. Networking

The gaming scenario is elevating, where the concept of online multiplayer is the uprising day after another. This requires a lot of communication between different servers, which is quite a headache to handle. But thankfully, the most popular game engines have this pre-built components and helper scripts, which shuns away the developer’s worry about the details of TCP/UDP traffic.


  1. Physics

Initially ignored in the gaming world, the law of physics has entered the entire picture of gaming to support the raising expectation of realistic look and feel. Game engines are of a great use here, as the developer does not have to code for every physical action or collision in the game.


  1. Graphical User Interface(GUI)

Each game engine has its own way of handling the entire thing called GUI. Some, ignore it completely. Some, makes the developer build the functions manually. And some comes with features that are capable of supporting basic GUI.


  1. Scripting

Pre-build scripts play a pivotal role in the creation of the game. Some call it ‘behaviour’, while others term it ‘game objects’. Either way, these scripts helps in controlling cameras, the relationship between different game elements and animation system.

Concluding Note:
Game Building is a job picked by a gamer mostly, rather than a non-gamer. And when, a developer, who is also a gamer, wants to build a new game; he/she uses the best of tools in the market. (We say it because we have quite a few in our team as well.) Since it is a very passion-oriented development job, we would like to share what we’ve learned of it so far. And are open to learning new things from you too. Either way, together, we’ll be building the game-developer community. So, feel free to get in touch with us, for the same, at Let’s game-code be on!
