Py2D game utility library

Py2D attempts to help game developers with commonly found tasks, especially in vector-based games.

The library is still in very early development, among the features so far are:

  • Classes for Vectors, Polygons and Affine Transformations with basic operations
  • Polygonal Field-of-Vision Calculation
  • Generate polygon obstructors from tile map data
  • Perform boolean operations (union, intersection, difference) on polygons
  • Grow and shrink polygons (polygon buffering, polygon offsetting)
  • Decompose polygons into convex parts

To learn more about features and how to get started, check out the Py2D website!

Cython support

Parts of Py2D can now be compiled to C modules using Cython. If you do a setup.py build install, you should get binary versions of the supported modules. Alternatively, for development, you can compile in-place by running

$ python setup.py build_ext --inplace
