Flappy

Flappy (the name stands for FLash-like APi for PYthon) is a cross platform multimedia library with the API very similar to the ActionScript 3 Flash API. Flappy is built on top of the SDL2 library and a slightly modified subset of c/c++ code from the OpenFL-Lime project.

Features

• Runs on Windows, Linux, Mac OS X
• GPU accelerated
• Drawing images, text, shapes, gradients
• Tile sheet batch rendering
• Flash-like display list, display objects, containers
• User input events and other events handling and propagation
• 3D graphics support

Current status

• Alpha version
• No Python 3.x support
• No sound playing

Install binary package

In Mac or Linux, try:

easy_install flappy

For windows, download the installer (one of Flappy-xxx.win32.exe files) here

Build from source

To build Flappy, Cython 0.19.1 or above is required.

Also the following libraries needed:

• SDL2
• freetype 2
• libpng 1.6
• libjpeg 6b

You can either install development versions of these libraries to your system (or already have them installed), and build and install Flappy like this:

python setup.py install

Or you can clone this repository to the same directory as Flappy's source directory and build and install with this command:

python setup.py build_extensions_with_waf --use-prebuilt-libs install

Quick example

This code draws a black-outlined orange circle inside a window sized 400x400 pixels. Each time you click on that circle you'll see the string "YAY!" in console output:

import flappy
from flappy.display import Sprite
from flappy.events import MouseEvent

class Example(Sprite):

    def __init__(self):
        super(Example, self).__init__()

        circle = Sprite()
        circle.graphics.lineStyle(4)
        circle.graphics.beginFill(0xff8000)
        circle.graphics.drawCircle(200, 200, 100)
        circle.graphics.endFill()
        self.addChild(circle)

        circle.addEventListener(MouseEvent.CLICK, self.on_circle_click)

    def on_circle_click(self, event):
        print 'YAY!'

if __name__ == '__main__':
    flappy.start(Example, width=400, height=400, title='Example')

For the comparison, here is the code in ActionScript 3 which does the same.

Help

For now, documentation is a stub. But you can take a look at ActionScript3 API reference for Flash. Classes and method in packages flappy.display, flappy.events, flappy.geom, flappy.text are very similar to the classes and methods in Flash's corresponding packages.
