The basic Knowledge of the Technology required for Metaverse Development

Programming to create a Metaverse

• Elements that make up a computer

Metaverse Development Company runs on various computers such as PCs and smartphones. What kind of understanding do you need to have in programming to make it work on various computers?

In fact, any computer has five functions: control, calculation, input, memory, and output.

All the elements that physically make up a computer , including the five major functions, are called hardware . Knowing the five major functions, you can see that there are only four types of program instructions: “input”, “memorize”, “calculate” and “output”.

why programming?

Hardware is just what a computer needs. Software is what commands the behavior of the hardware . In software, we classify OS (basic software), which creates an environment for applications to run on a computer, and software other than the OS as applications.

The OS acts as an intermediary between the created application and the hardware, and if the same OS is used, it will work even if different hardware is used . If all computers run on the same OS, one application can be completed, but since there are a wide variety of OSes, it is necessary to create applications using the programming language that corresponds to the OS to be used.

Developing desktop applications

• Application for PC

An application that runs on a PC is called a desktop application.

A feature of desktop apps is that they work regardless of hardware as long as the application you use matches the OS in your PC. Currently, one of the Metaverse Development Services apps with the most users, “VRChat” is also a desktop app.

• Desktop app features

Currently, most of the hardware such as VR goggles is targeted for operation on PC. As an advantage of the desktop application, if you want to use XR hardware such as a head-mounted display in the Metaverse world, you can link it relatively easily compared to other application environments. In addition, security for each OS becomes a problem in order to operate the hardware in detail, but the desktop application is relatively flexible and easy to operate.

Also, if you can only target high-performance PCs, you can create richer 3D expressions than other environments, and express realistic world views and flashy productions.

However, there are also disadvantages. In order to operate the desktop application, it is necessary to install and copy it. When using desktop applications in actual development, it is necessary to consider the hurdles involved in installing and copying. Since it works inside a PC, it is highly dependent on the OS and basically does not work on different OS. If you want to run it on a different OS, you need to provide it separately according to the OS.

Development of smartphone applications

• Application for smartphone

Smartphones continue to evolve year after year. Now, if you have a smartphone, you can do most things, although not as much as a PC. An application that runs on a smartphone is called a smartphone app

Web application development

• Application for web browsers

Desktop apps and smartphone apps require installation and copying the first time you use them. This raises the hurdle for users to experience it, and there is a possibility that the content will be difficult to experience casually.

Therefore, what is increasing these days are services offered over the Internet. Not only SNS such as Facebook and Twitter, but also online shopping such as Amazon and Rakuten, and search services such as Google and Yahoo! An application that runs on a web browser is called a web application . A web application runs on a web server, and users can experience the service as soon as they have a web browser.

Advantages and disadvantages of web applications

The advantage of developing the Metaverse Intergration Services as a web application is its ease of use. There is no need to register the application in the store, and content can be easily published simply by uploading the application data to the web server. In addition, since content can basically be displayed on any device that runs a web browser, a single application can be developed to support various devices and operating systems.

On the other hand, web applications still have some issues. Web browsers have various security measures in place so that even non-developers can use them safely, and they may not be able to control the hardware very well. You also have to be aware of various limitations of the web browser itself, such as memory and 3D rendering limitations.

Programming languages ​​used in Metaverse

• language used by the OS

The programming language varies depending on the OS and environment used.

Taking smartphone apps as an example, for Android, Kotlin, Java, C#, etc. are candidates. For iOS, Swift, C#, etc. are candidates.

C# is compatible with both OSs, but depending on the language, such as Kotlin or Swift, it may only be compatible with some OSes.

In order to make such a language compatible with multiple OSs, development man-hours increase because different programming languages ​​are used according to the OS. Metaverses are often developed so that they can run on a variety of OSes, so languages ​​that can support multiple OSes are becoming mainstream. Supporting multiple operating systems in this way is called multi-platform.

Script language and native language

The REALITY and Cluster languages ​​in use C# as well as Kotlin and Swift. If you use only C#, the smartphone application can be completed in one language, but why are you using it?

Kotlin and Swift are languages ​​for smartphone apps. Unlike C#, this language is called a native language that can be executed directly from the CPU. Conversely, languages ​​that are not native languages ​​are called scripting languages . Although native languages ​​support fewer OSes, they are advantageous in terms of execution speed and can use functions installed in the OS.

It is also worth remembering that recently, there are an increasing number of methods that achieve both control of development costs and processing performance by using a script language as a base and partly developing in a native language .

Development using a game engine

Development using a game engine that is often used in the Metaverse

Almost all current Metaverse Token Development Company are developed using game engines. A game engine is software that is used to develop games.

Game development has many common elements such as graphics drawing, input, sound, physics simulation, asset management, AI, etc., and a mechanism for easily implementing them is provided. By using a game engine, you can use the advanced development system provided by the game engine simply by writing a simple program. It is also possible to check the operation by implementing some processing without writing code or executing it even during production. As a result, it becomes easier to efficiently reduce development time and provide high-quality content.

Most used game engine

• The world’s most popular game engine

Unity is a game engine provided by Unity Technologies in the United States. It is the most used game engine in current Metaverse development. It supports a wide range of genres such as game apps, VR/AR, and 2D games, and covers the basic functions required for a game engine. All well-known Metaverse apps such as VRChat are created using Unity.

Unity programming method

• There are two types of Unity programming: C# and Visual Scripting.

In C#, create a file for the program as usual and write the code from the text editor. In order to program while using the functions prepared in advance within Unity, it is possible to easily use Unity functions in addition to normal C# functions. For example, in the C# program in, the function Start is prepared from the beginning, and the program described in the Start part is automatically executed at startup.

The second method is Visual Scripting, which uses block statements (nodes) instead of code. We will program by connecting boxes with nodes. Programming by connecting nodes instead of code is called visual scripting . Visual scripting is a relatively new programming technique. Visual scripting was originally developed to allow non-programmers to program, so it is relatively easy to learn compared to C#.

Both can implement the same functions, but Visual Scripting is faster and easier to visualize the actual running state, and C# allows you to freely implement a wide range of functions with good performance. Both have their merits and should be chosen according to the situation .
