If you’re a programmer looking to integrate your favorite language into Unity, you’ve probably considered using C++. C++ is a powerful and fast language that can be used for a wide range of applications, from gaming to graphics programming. However, integrating C++ with Unity can be a complex process, so it’s important to understand the basics before diving in.
In this article, we will explore the different ways you can use C++ with Unity, including:
Using C++ Plugins
Unity supports the use of plugins, which are third-party code modules that can be added to your Unity project. One way to use C++ with Unity is by creating a C++ plugin that can be imported into your Unity project.
To create a C++ plugin for Unity, you will need to have some experience with C++ and Unity’s plugin architecture. You will also need to have the appropriate development tools installed, such as Visual Studio or Xcode.
Once you have created your C++ plugin, you can import it into your Unity project by following these steps:
- Create a new folder in your Assets directory and name it “Plugins/C++”.
- Drag your C++ plugin DLL file into the new folder.
- In your Unity project, go to Edit > Project Settings > Packages and click the “+” button to add a new package.
- Choose the “C++” package type and select the folder you created in step 1.
- Build and run your Unity project.
Writing Managed Code using C and C++ Interop
Another way to use C++ with Unity is by writing managed code using C and C++ interop. This involves creating a C++ DLL file that can be called from C code in your Unity project.
To create a C++ DLL file that can be called from C, you will need to have some experience with C++ and C interop. You will also need to have the appropriate development tools installed, such as Visual Studio or Xcode.
Once you have created your C++ DLL file, you can import it into your Unity project by following these steps:
- Create a new folder in your Assets directory and name it “Scripts/C++”.
- Drag your C++ DLL file into the new folder.
- In your Unity project, create a new C script and add a reference to the C++ DLL file.
- Write C code that uses the C++ DLL file’s exported functions.
- Build and run your Unity project.
Building Native Scripts
The third way to use C++ with Unity is by building native scripts. This involves creating a C++ script that can be used in your Unity project without the need for a plugin or managed code.
To create a native script using C++, you will need to have some experience with C++ and Unity’s scripting API. You will also need to have the appropriate development tools installed, such as Visual Studio or Xcode.
Once you have created your C++ script, you can import it into your Unity project by following these steps:
- Create a new folder in your Assets directory and name it “Scripts/Native”.
- Drag your C++ script file into the new folder.
- In your Unity project, go to Edit > Project Settings > Scriptable Objects and click the “+” button to add a new scriptable object.
- Choose the “C Script” option and enter a name for your script.
