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
1. Explore the site. Run Worlds.
- Explore the menu bar. Browse the lists of Worlds. Click World images to run them. See How to run Worlds.
- Read the Quick overview and List of features and Introduction.
2. See how coding on this site works. Do the Tutorial.
- Work through the Start Tutorial. This shows you how coding on this site works. This does not assume you have ever written a program.
- See How to write code on this site. When coding, see the "Docs" menu for all the documentation you need.
- The tutorial looks at coding the following Worlds:

3. Learn how to program with JavaScript. Do the courses.
- You can learn how to program in the course: Foundations of Programming in JavaScript. This does not assume you have ever written a program.
- This course uses the P5 graphics library.
- You can learn WebGL with P5 in the WebGL course.
- When you are finished these courses, you will be able to make Worlds like the following:

4. Modify some Starter Worlds.
- If you have learnt a little programming, start modifying existing Worlds.
- Pick one of the following 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.
- The following Starter Worlds use the Three.js graphics library. This site supports many libraries.
