Coders: Make 3D worlds and share them with friends. Clone and edit other people's worlds. Make touch mobile games. Embed your worlds on other sites.
Teachers: Run programming practicals in 3D or 2D or text, with many features designed for teachers. Safely edit and run student code.
Researchers: Upload problems, tender for solutions, test and rank them. Make hybrid AI systems from the code of multiple authors.
Gamers: Play the endless game worlds the coders make. Come and browse an ever-growing archive of games.
Learners: Clone other people's worlds and change one or two lines. What's the worst that could happen?

How to get started

Explore the site. Run Worlds.


See how coding on this site works.

  • See How to write code on this site.
  • When coding, see the "Docs" menu for all the documentation you need.


Do the Starter Tutorial (P5)

  • The "P5" graphics library is probably most suitable for beginners. More experienced programmers may prefer to skip P5 and use the "Three.js" graphics library (below).
  • To get started coding JavaScript on Ancient Brain with P5, work through the P5 Starter Tutorial. This shows you how coding on this site works (with P5). This does not assume you have ever written a program.
  • The tutorial looks at coding the following World:
One Cube World (P5)
By Starter user
Simple starter World (P5 version). No camera control. So cube rotates to show 3D.
Do the Programming courses (P5)

  • You can learn in depth how to program in JavaScript in P5 by doing the course: Foundations of Programming in JavaScript. This does not assume you have ever written a program.
  • When you have done that, you can do the more advanced WebGL course (JavaScript 3D graphics in P5).
  • When coding, use the P5 reference material.
  • When you are finished these courses, you will be able to make Worlds like the following:
Tutorial 7.3
By "Coding Train" project
Arrays of Objects
Tutorial 18.7
By "Coding Train" project
Tutorial 18.7 with full canvas, resized model, sound. Texture on box is image from another user.
Tutorial 7.8 variant
By "Coding Train" project
Tutorial 7.8 with music and other uploaded images, including from other users. Click on the images.
Tutorial 2.1
By "Coding Train" project
Variables in p5.js (mouseX, mouseY)
Do the Starter Tutorial (Three.js)

  • The "Three.js" graphics library is more suitable for programmers with a little experience. Beginners may prefer to start with P5. If you know a little P5, you will be ready to try some Three.js.
  • To get started coding JavaScript on Ancient Brain with Three.js, work through the Three.js Starter Tutorial. This shows you how coding on this site works (with Three.js). This does not assume you have ever written a program.
  • The tutorial looks at coding the following World:
One Cube World (Three.js)
By Starter user
Simple starter World (Three.js version). Cube of random color. Built-in camera control.
Do a Programming course (Three.js)

  • There is not yet on this site a full course in programming in Three.js.
  • You are directed to the Three.js reference material.
  • There are plans to partner with the book 3D Game Programming for Kids. You can go through this book and code the examples on Ancient Brain. This book does not assume you have ever written a program.
  • When you are finished this book, you will be able to make Worlds like the following:
1. Shapes
By "3D Game Programming ...
Port of code "shapes" from Ch.1
3. Making an Avatar
By "3D Game Programming ...
Port of code "building_an_avatar" from Ch.3
Modify some Starter Worlds.

  • If you have learnt a little programming, start modifying existing Worlds.
  • Pick one of the Starter Worlds. "Clone" it, and edit your copy.
  • The easiest parts of the code to change are in the "tweaker's box" at the top.
