Unity 2D and 3D Game Development


Unity is a game development engine that allows you to build powerful 2D and 3D games for a range of platforms and devices including Mac, Windows, iPhone, Android, game consoles, and even virtual reality devices! You can start using Unity for free to build 2D or 3D games. Here you will find a range of free tutorials to help you get started with Unity. These tutorials will show you how to build your own 2D and 3D games in Unity using the C# programming language.

By learning how to develop games in Unity using the C# programming language you will also learn skills in this language that you can take to desktop application design and mobile application design (and there are plenty of tutorials here for that!).

If you haven’t already checked out the Maya 3D tutorials, make sure you do so that you can build more advanced characters and objects for your 3D game environment. 3D models made in Maya can be easily imported into Unity. To get started, it is suggested you begin with the 2D game design tutorials but if you want to jump into 3D game design (scroll down for this) then you can still do that without any prior experience.

To get started, select a 2D or 3D game design tutorial and most importantly…have fun learning!
