Consider using "SDL_Event *" instead.

Please add pygame.mask

I'm using pygame.mask to detect object in TMX please update it

Add LGPL notices to pygame files

While most of the files we've imported from pygame (excluding those in tests) have the appropriate LGPL license notices, we've been rather lack about adding them and appropriate copyright holder notes to the rest of the project. This should be fixed.

"event post blocked" when music finishes playing

My game uses pygame.mixer.music.set_endevent() to register an event type to be used when music playback is complete. Running my game with pygame_cffi and PyPy, the following traceback was logged when the queued music file finished playing, and the registered event was never observed. I don't get this traceback with standard pygame in cPython.

Traceback (most recent call last):
  File "/home/josh/.local/lib/pypy2.7/site-packages/pygame/mixer_music.py", line 207, in _endmusic_callback

Segfault

Hi!
So have been using pygame_cffi for a while and one day noticed that one of my programs using pygame_cffi would segfault once in a while.
I figured out what causes it and how to reproduce:

import pygame
import time

pygame.init()
surface = pygame.display.set_mode((800, 800))

color = [255, 127, 0]
pos = (656, 800)
radius = 0
width = 0

pygame.draw.circle(surface, color, pos, radius, width)

objects in my program would get smaller with distance sometimes their radius would reach zero, not often though. so initially i did not pick it up.

if width > radius it throws width greater then radius.
and if radius > width it would work fine.
so it is only in the case of radius = width = 0
that it would segfault.

for me it's an easy fix i can live with

    if radius == 0:
        radius = 1

but it shouldn't segfault.

Too many open files error (fonts related).

A lot of games written with pygame uses functions like this:

    @staticmethod
    def display_single_line(line, x, y, screen):
        """Displays a single line of text on Battle screen"""
        txt = pygame.font.Font(None, 36)
        render = txt.render(line[0:13], 0, (255, 255, 255))
        screen.blit(render, (x, y))

So font file being opened every time when function is called. But this error doesn't happen in PyGame.
Maybe we should add caching or something like it?

event.unicode is sometimes an int

Which is a bit unexpected.

To reproduce: clone pypy, go to directory (like rpython/jit/metainterp)
and run py.test --view test/test_loop.py

then once pygame pops in press "/" to search

pygame.joystick

Clearly this is not implemented yet. Is there an eta on this?

Support restricting events returned by pygame.event.get

pygame.event.get and pygame.event.clear support restricting the events pulled or removed by type.

pygame_cffi currently doesn't.

Add an AUTHORS file.

A bunch of different people have now contributed to pygame_cffi. We should give them credit.

Adding missing pygame.draw functions

pygame_cffi currently doesn't support

• pygame.draw.aaline
• pygame.draw.aalines
• pygame.draw.arc

There's also a TODO item in the surface checks that should be completed.

Update to use out-of-line CFFI 1.0 building

CFFI 1.0 allows pre-building the necessary C modules which massively reduces import times. on slower machines (e.g. Raspberry Pis).

Add support for pygame.PixelArray

Currently there's no support for this object.

ImportError: No module named pygame._sdl_c

I seem to have a problem with this module on Mac OS X 10.11 Golden Master.

Running "import pygame" causes the following error:

To install it, I ran:

brew install pypy cairo jpeg
git clone https://github.com/CTPUG/pygame_cffi.git
cd pygame_cffi
pypy setup.py build build_ext -n -I/usr/local/include
sudo pypy setup.py install build_ext -n -I/usr/local/include

I included "/usr/local/include" because it couldn't find "jpeglib.h"

Add support for pygame.math.

Currently we don't have this module.

pygame_cff unpack_rect is too restrictive

with stock pygame:

>> pygame.surface.Surface((120.0, 122.8)) <Surface(120x122x32 SW)>

With pygame_cffi

``>> pygame.surface.Surface((122.0, 122.8))
....
TypeError: expected tuple of two integers but got <type 'tuple'>`

This causes problems with programs that pass floats (usually created by some mathematical operation) when creating surfaces

Add a pygame.version attribute.

Pygame appears to have a .version attribute in the top-level package that, e.g., pyknic, relies upon.

Add freesansbold.ttf (maybe *.ttf) to files included by MANIFEST.in.

Currently it appears to not be installed by pip install pygame-cffi.

Hook up Travis CI.

pygame.image.load() should accept any file-like object.

In pygame proper, pygame.image.load() accepts any file-like object (e.g., a StringIO object), but this results in a TypeError in pygame-cffi.

OverflowError: integer 32769 does not fit 'int16_t'

i encountered this error/bug when running my pygame code.
i think it happens where a to big value for x is entered and can not be stored in a int16_t.
in my case it was a entity in my code going far offscreen.

this is the full traceback:

Finish pygame.transform

The following functions from pygame.transform aren't complete

• threshold
• average_color
• average_surfaces
• laplacian

Replace ffi.callback usage with cffi's "Extern Python" syntax

We should convert to using cffi-1.4's Extern “Python” syntax for callbacks, to avoid the issues with the ffi.callback approach.

Should test with pypy

Since one of the goals is to provide pygame for pypy, we really should run the test suite against pypy.

Since travis only has horribly outdated versions of pypy available, this will require rolling our own logic for setting up pypy.

We should also try using the travis OSX target sometime.

how do i install?

pygame.transform.smoothscale not implemented

Anyone have any plans to implement?
