Ancient Brain Starter Tutorial (P5)

This tutorial shows you how to get started on Ancient Brain (P5 version).

To be precise, this shows how to start coding on Ancient Brain in the JavaScript programming language, using the P5 library for the graphics. (You can use other libraries for graphics, notably Three.js.)

On Ancient Brain, you can edit and run programs in the browser, with no install. You have to register and get a username if you want to save your creations.

This tutorial will show you how to copy and edit a simple "World" called "One Cube World". (Click on World image to run it.)

You will soon be able to make variants of this World, such as the ones shown here.
