Latest Version: 1.4.1

Pylash is a game engine for python which imitates some classes and functions in flash. We develop pylash with Python3 and the GUI engine of pylash is PyQt4. Many classes which are almost from flash such as Sprite, BitmapData, Bitmap, TextField, Loader and Graphics will be found in pylash.
