Plus, it provides the satisfaction of seeing your hard work and imagination come to life in the form of a fully functional game engine. So roll up your sleeves, grab a cup of coffee, and let’s dive into the world of game engines together.

1. Understanding the basics of game engines

Game engines are an essential component in the development of video games. A game engine is responsible for handling functionalities such as graphics, physics, and AI. In this section, we will be covering the basics of game engines, which will set a foundation for creating a game engine from scratch.

2. Choosing a programming language

The first step in creating a game engine is to choose a programming language to write the code. There are various programming languages to choose from, including C++, C#, Java, and Python. Each language has its pros and cons, and the choice of language will depend on the type of game engine you want to develop.

3. Planning the architecture of the game engine

The architecture of a game engine is crucial as it determines how the different components of the engine will interact with each other. Planning the architecture beforehand will help you to have a clear understanding of the different components that need to be developed and how they will work together.

4. Setting up the development environment

Before you start developing the game engine, you need to set up the development environment for your chosen programming language. This involves installing the required software such as an IDE (Integrated Development Environment), a compiler, and any other necessary libraries.

5. Creating the core engine framework

The core engine framework is the backbone of the game engine, and it includes functionalities such as rendering graphics, handling physics, and controlling the game’s logic. Creating the core engine framework is a significant milestone in the development of the game engine.

6. Incorporating 3D graphics into the game engine

Video games rely on 3D graphics to create immersive environments for the players. Incorporating 3D graphics into the game engine involves creating the necessary rendering pipeline, shaders, and other required components.

7. Implementing physics simulation

Physics simulation is an essential component of any game engine. It enables the game to simulate real-world physics such as gravity, collisions, and forces. Implementing physics simulation involves writing code to simulate physics and integrating it into the core engine framework.

8. Creating an AI subsystem

Many games require some level of artificial intelligence to make the game more challenging and believable. Creating an AI subsystem involves writing code that allows the game engine to generate intelligent behavior for non-playable characters (NPCs) in the game.

9. Adding game-specific features

Once the core components of the game engine are in place, it is time to add game-specific features such as mechanics, game rules, and user interfaces. Adding game-specific features will depend largely on the type of game being developed.

10. Testing, debugging, and optimizing the game engine

Testing, debugging, and optimizing are critical stages in the development process of any software. It involves identifying and fixing bugs, ensuring the game engine’s performance is optimal, and testing the engine to ensure that the final product works as intended. These stages should be carried out iteratively until the game engine is stable and ready for use.

Understand the Basic Components of a Game Engine

If you are planning to make a game engine, it is vital to understand the basic components of a game engine. Below are the essential elements that you should include:

Rendering Engine

One of the necessary components of a game engine is the rendering engine, responsible for handling all the visuals. This engine typically includes 3D meshes, texture maps, lighting, and special effects. The rendering engine needs to be optimized to achieve high frame rates.

Physics Engine

Another critical component is the physics engine, responsible for handling collisions, gravity simulation, and object movements. It is an important part of any game engine.

Audio Engine

Your game engine should also have an audio engine that handles all of the in-game sounds, whether it be music, sound effects, or voiceover. The audio engine should support various formats and provide 3D positional sound support.

Scripting Engine

A scripting engine will allow developers and designers to code complicated game logic and create custom gameplay mechanics. It makes the game engine more flexible and more accessible for users who are more comfortable with scripting languages such as C++, LUA, or Python.

User Interface Handling

The game engine should have robust and straightforward user interface handling, allowing users to interact with the game and providing feedback.

Network Engine

The network engine is responsible for enabling online multiplayer modes, supporting multiple players, and managing the network connections. It is an important part of any gaming engine that supports multiplayer modes.

Resource Management

A game engine needs to have efficient resource management allowing it to handle several textures, mesh models, audio files, video files. The engine should access or load the resources only when necessary.

Artificial Intelligence Engine

The Artificial Intelligence (AI) engine is responsible for enabling non-player characters (NPC) to behave intelligently. It should be able to simulate human-like behavior with distinct personalities, goals, and preferences.

Debugging and Profiling Tools

Every game engine should include robust debugging and profiling tools that allow developers to identify and resolve crashes and bugs.

Level Editor

Lastly, the game engine should have a level editor, a tool for designing and creating new levels, testing them in real-time, and making necessary changes. It should be user-friendly and should provide a visual and comfortable work environment.

Understanding these basic components will give you a clear idea of what you need to do to make a game engine. Once you understand these components, it’s time to dive into the development process.

Types of Game Engines

When it comes to making a game engine, there are a myriad of options available to developers. Each type of engine has its own strengths and weaknesses, and choosing the right one for your project is crucial. Here are some common types of game engines:

2D Engines

2D engines are perfect for games that don’t require a lot of depth, but still need to be visually appealing. These engines are great for platformers, RPGs, and many mobile games. Some popular 2D engines include Phaser, Construct, and GameMaker.

3D Engines

If you’re creating a game with complex 3D graphics, then a 3D engine is your best option. These engines are perfect for first-person shooters, racing games, and open-world titles. Examples of 3D engines include Unity, Unreal Engine, and Godot.

Mobile Game Engines

As the name suggests, mobile game engines are designed specifically for creating games on mobile devices. These engines often include features like touch screen controls, gyroscopic sensors, and the ability to work with a variety of devices. Some popular mobile game engines include Corona, Cocos, and Gideros.

Web-based Engines

Web-based engines are perfect for creating games that are playable through web browsers, without having to download any additional software. These engines are often used for creating browser games, which are typically less complex than full-fledged computer or mobile games. Examples of web-based engines include NectarJS, HTML5, and RPG Maker MV.

Custom Engines

Sometimes, developers opt to create their own game engine from scratch. This approach gives developers complete control over the engine’s features and capabilities. However, building a custom engine can be time-consuming and requires a lot of expertise. However, if you’re willing to put in the effort, a custom engine can produce some truly excellent results.

In conclusion, determining which type of engine to use is a crucial first step when beginning to make your own game engine. Consider the type of game you want to create, your skill level as a developer, and your resources before making a decision. Once you’ve made your choice, you’re ready to dive in and start creating your own game engine!
