A Rimu Tutorial

Have you ever heard of turtle geometry?

Watch on tube.arthack.nz (opens in a new tab) or archive.org (opens in a new tab)

We could implement a Logo-inspired turtle game using Rimu, where kids could move turtles with code.

- setwidth: 10
- setcolor: 4

- right: 18
- forward: 50

- $map: range(5)
  each:
    - right: 144
    - forward: 50
    - left: 72
    - forward: 50

Then the output is a list of commands for the turtle to execute.

Now we might start to think about a better data model, how do we want users to describe their turtle actions?

Actions

- $type: "set"
  width: 10
  color: 4
- $type: "rotate"
  right: 18
- $type: "move"
  forward: 50
