WARNING: A work in progress currently.

A re-implementation of Python's turtle module, with some improvements.

Main improvements are:

• timed-based animation model, turtles move same speed regardless of CPU speeds
• animation in separate engine for easier use in game/simulation loops
• faster maths, including C acceleration
• unit tests and cleaner design for further extending
• pluggable output rendering:
  • builtin Tk renderer reuses stdlib's turtle renderer
  • companion library Turgles provides fast OpenGL renderer
  • stdout renderer for debugging
  • can be headless for pure simulation

Other goals/ideas

Other renderering backends: svg, gif, network

System Requirements

python 2.6/2.7/3.2/3.3/PyPy

On linux systems, you may need to install python-tk as well.

If you want to use the Turgles OpenGL renderer (encouraged), then you'll need to install that also. See http://github.com/AllTheWayDown/turgles for details

Running

Currently there are two demo programs that create a single turtle. To run, use

python -i tk_demo.py

or

python -i gl_demo.py

You then have a python prompt with a turtle t that you can control as normal. e.g. t.forward(100), t.left(90), etc
