Simple starter World (P5 version). No camera control. So cube rotates to show 3D.
How to write JS on Ancient Brain
Explains how to code in JavaScript (JS) on Ancient Brain. To create a World, you need to register and log in. Click a World name to go to its "home page" where you can take actions. Edit code in the browser. Run direct from the editor. Explains ways to output data. Explains how to include another JS file.

How to write a World
To code a World, make a blank new one, or "clone" an existing World and change it. Worlds are written for a specific "API". Explains World screenshots. Explains how to upload support files and use them. Explains how to do keyboard, mouse and touch interaction.
How to write a World that uses no Mind

How to write a Mind
Step-by-step guide. Explains how Minds can call other Minds. This is the AI model behind Ancient Brain.
We have various online courses where you can learn to code in JavaScript on Ancient Brain. They are listed in the "Learn" menu. Pick a course and do it.

We will now explain the courses we have.

This is a proper Introduction to Programming course, with videos, using JavaScript and P5. This does not assume you have ever written a program.

This AI course does not have a full set of notes explaining AI theory. You will need to get that somewhere else.

Rather this is a series of online AI programming exercises, with problems for students to solve. These exercises could be used to accompany a full AI theory course (and indeed have been used for that). All code is in JavaScript using P5.

AB object
Ancient Brain runs have an "AB" object defined, which provides lots of built-in functionality and customisability on every run. This is a full reference for the data and methods of the AB object.
AB World and Mind definitions
You define Worlds and Minds by defining methods for AB.world and AB.mind. Then Minds can run in Worlds. This explains the syntax.
AB legacy code
Explains some legacy code you might see in some people's Worlds. One of the core principles of Ancient Brain is that old Worlds will run forever.
Types of runs
Explains how to run "logged in". Explains how to send extra information to runs.

APIs
A summary page of all the APIs. Compares them by libraries used and functionality.

Resources
Some useful links for how to get resources online, such as textures, 3D models and sound effects.
Ace editor
Links to the official Ace editor docs, and quick reference. Explains the "Intelligent code help".
