Is C++ used in Unity for game development or scripting?

Unity3D does not use C++ for standard game scripting; instead, it uses C# for development and gameplay logic. The Unity3D engine itself is built in C++ to manage core functionality, graphics rendering, and physics. Developers can extend Unity's capabilities with C++ by creating native plugins, particularly when advanced system-level integration or custom optimisation is required. However, C++ is not used directly for scripting within Unity projects.
