IL2CPP is a Unity build feature that will compile your code into C++ code instead of the .NET IL (intermediate language).
The benefit of this lies with the differences between managed vs unmanaged programming languages.
Managed vs Unmanaged Code #
When it comes to programming languages, the terms “managed” and “unmanaged” refer to how the language handles memory management. In a managed language, the language itself takes care of allocating and freeing up memory as needed. This makes it easier for the programmer to focus on writing the code itself, without having to worry about memory management.
One of the benefits of using a managed language is that it can help prevent memory leaks. In an unmanaged language, it is easy to accidentally allocate memory that is never freed up, which can lead to memory leaks. These leaks can cause the program to slow down or crash, and can be difficult to detect and fix.
In a managed language, the language itself takes care of freeing up memory that is no longer needed, so there is less chance of a memory leak occurring. This can make the code more stable and less prone to errors.
One example of a managed programming language is C#, which is commonly used in the Unity game engine. Unity offers a technology called IL2CPP (Intermediate Language to C++) that can be used to convert managed code, such as C#, into native code. This has several benefits, including improved performance and the ability to run the code on a wider range of platforms.
One of the key benefits of using IL2CPP in a Unity project is that it makes it harder to reverse engineer the code. Since the code is converted into native code, it is more difficult for someone to decompile it and see how it works. This can help protect the intellectual property of the game or application, and make it harder for hackers to access or modify the code.
In addition, using IL2CPP can help improve the performance of the game or application. Since the code is converted into native code, it can run more efficiently on the target platform. This can result in faster load times and better overall performance.
In summary, the use of managed languages and technologies like IL2CPP can provide several benefits for game development with Unity. In addition to making it harder to reverse engineer the code, IL2CPP can also improve performance and provide the flexibility to run the code on a wider range of platforms. This can help protect the intellectual property of the game or application, while also providing a better experience for the user.
