The Unity Playground is a personal project I've been developing as a resource for my activity of Evangelist, and also to complement the volunteer work I've done in places such as CoderDojo. Playground has been used by me and other people around the world to deliver workshops to beginners of all ages.
After two years of open development on Github, the Playground has landed on the Asset Store thanks to the help of the Unity Education Content team in Brighton.
What is it
It is a collection of simple scripts to create 2D physics games, intended for giving workshops to an audience of beginner game developers to quickly enable them to make games in Unity. It is intended to be as flexible as possible, not enforcing a specific game genre apart from the obvious constraints of being 2D and physics-powered. It contains a lot of scripts that perform atomic tasks (that is they do mostly only one thing) so you can combine them to create any kind of gameplay.
That said… the audience should already have an idea of how Unity works, the Editor interface, the concept of GameObjects, Components, the Scene View, Play Mode, and so forth. It might be useful to guide them through these concepts before letting them play with this project.
Extended documentation is included in the project, or you can find it on the Unity Learn website.
Where to find it
You can download the Unity Playground for free on the Asset Store.
If you want to follow the development and contribute to it, the full project currently resides on Github at this address: https://github.com/Unity-Technologies/UnityPlayground/.
What it contains
The project contains a collection of scripts, each one with their custom Inspector. Additionally, it provides a bunch of graphics, but you can feel free to add your own or substitute them altogether. It also comes with a collection of Cheatsheet images that can be printed and used as a reference when giving the workshop.
