## Overview
Unity is an all-purpose game engine that supports 2D and 3D graphics, drag and drop functionality and scripting through [C#](https://guide.freecodecamp.org/csharp).
Unity is particularly popular for mobile game development and much of their focus is on mobile platforms. Unity3D's 2D pipeline is a more recent addition to the engine, and is less mature than the 3D pipeline. Despite this Unity is an adequate platform for developing 2D games even when compared to other dedicated 2D engines, particularly if you plan to release the game across multiple mobile devices due to its ease of access of building for different platforms.

Unity is also a good choice for VR development, although VR is a very small market at the moment, but growing. The mobile and PSVR markets are the largest in VR, and Unity is already well positioned to port games to many platforms such as PS4 and PC, or many different mobile markets. Unity also allows the development of AR Content and has training sessions with both VR and AR articles.
The engine targets the following graphics APIs: Direct3D on Windows and Xbox One; OpenGL on Linux, macOS, and Windows; OpenGL ES on Android and iOS; WebGL on the web; and proprietary APIs on the video game consoles.
Additionally, Unity supports the low-level APIs Metal on iOS and macOS and Vulkan on Android, Linux, and Windows, as well as Direct3D 12 on Windows and Xbox One. Within 2D games, Unity allows importation of sprites and an advanced 2D world renderer.

For 3D games, Unity allows specification of texture compression and resolution settings for each platform that the game engine supports, and provides support for bump mapping, reflection mapping, parallax mapping, screen space ambient occlusion (SSAO), dynamic shadows using shadow maps, render-to-texture and full-screen post-processing effects.

4) Section 4. <b>Project</b>: This is your project window. Basically it show what's inside Assets folder on your disk. Everything from Game Objects, Scripts, Textures, Folders, Models, Audio, Video and etc... will be accessible from this window.

4. <b>Profiler</b>: This section allows us to profile our game. Here we can see the performance, memory usage, fps and other characteristics of our game and which function, script, object, etc. is causing how much effect on the quality of our game.
5. <b>Asset Store</b>: If we are logged into our Unity account in the editor, we can directly access the Unity Asset Store and download and import the required assets into our project.
Unity Editor interface is heavily customisable as each section in window can be resized and docked anywhere in the editor as per our requirements. It is also possible in Unity to create custom windows and editor tools via script.
