new buffer code from Lenard

René Dudfield — 2013-06-19T08:04:41

Hellos,

Lenard made some new buffer improvements to pygame.  If anyone has time to
test it with their apps that would be cool.  Just installing it from
source, and seeing if your app still works ok.  Especially if you use any
of the buffer related code directly.

https://bitbucket.org/pygame/pygame/


Here's the notes from WHATSNEW...

    Add full Python new buffer protocol support to Pygame 1.9.2. In addition
    Python level array interface support is added to several Pygame objects
    and function. This changeset marks the end of a series of commits,
    starting with revision 98e3a61592c1 on September 8, 2012.

    Affected Pygame buffer exporting objects are BufferProxy, Surface
    (through method get_buffer), Sound, PixelArray, and Color. Affected
    importers are Sound, freetype.Font, BufferProxy, and the
    pixelcopy module functions (array_to_surface, surface_to_array,
map_array,
    and make_surface).

    Internally, Pygame has been rewritten to use the C Py_buffer to
represent
    external

Hello again.

Thank-you for this! I now have a beautifully blitting tile system! Thanks
so much for the assistance!

Hello,

Is pygame.event and its post method another way of creating a system like

playing sound on Windows

Hi all,
I've just subscribed to this list hoping someone can hplease elp me with the
following problem: I wrote the class bellow (I also attached it) that simply plays a sound
file when its method play_file() is called. It works on Linux perfectly, but
on Windows, no sound is played and I do need to find the reason of it. 
Configurations are:
Windows 7 (32 bits), Python 2.6 and Pygame 1.9.1 (win32). Thank very
much for any help!

Hi Radomir,

Thank-you for the clarification!

Just a quick question regarding this solution before I attempt to implement
it.

If a FULL tiles height is 80px, but only 40px is visible due to the overlap
(except in the bottom row). How many pixels are each of the letters you've
described? 20px or 40px?

Cheers

Hi

You probably could use the pygame.sprite.LayeredDirty and use the y axis 
as for the layer (smaller y means behind).

If I remember correctly, the dirty flag should handle the rest (it 
redraws the parts that are affected by a dirty sprite).

Make sure you use convert or convert_alpha and maybe the RLEACCEL flag 
for blitting (this might give you a performance boost).

Let me clarify.

Looking from the side, you have something like this:

a..
Ab.
.Bc
..C

where small letter is the top part of a tile, and capital letter is a
bottom part and horizontal axis is time. Now, what you are doing right now
is:

1. blit the bottom tile:

a..a
Ab.A
.Bc.
..C.


2. blit your current tile:

a..a.
Ab.Ab
.Bc.B
..C..

3. blit the top tile:

a..a..
Ab.Ab.
.Bc.Bc
..C..C

As you pointed out, this damages the tiles that are further down or up in
that column. Now, what you need to do is to modify your top and bottom tile
blitting like so:

1. blit just the bottom half of the bottom tile:

a...
Ab.A
.Bc.
..C.

2. blit your current tile whole:

a....
Ab.Ab
.Bc.B
..C..

3. blit the top part of your top tile:

a.....
Ab.Ab.
.Bc.Bc
..C...

This way you don't damage the other neighboring tiles.

I hope that helps.

Hello,

Thank-you for your quick response.

Unfortunately, because a unit is "taller" than a tile, their head pokes
over the top of the tile above (the overlap causing the depth) - which is
where the feet of the unit in the tile above are.

So, erasing the first tile, means you lose the feet of the tile above. If
you run the code provided, you'll see what I mean.

The code simply draws a wall on the grid. Then at random intervals, it
draws a unit in either the tile above the wall, or the tile just above
that. If a unit is already in the randomly chosen tile, it attempts to
remove it. The "remaning" head problem can be seen clearly from just
running this for a few seconds.

Any code change advice is hugely welcomed here!

The trick is no not redraw the neighboring tiles in whole, but just
the parts that overlap with your current tile. Then they won't mess
*their* neighboring tiles.

Complicated Blitting Order Issue

Andrew Barlow — 2013-06-16T11:19:05

Hello,

I have a fairly frustrating problem I am trying to solve. It's pretty
complicated to explain, so I'll do my best.

I am trying to use the depth effect of StarPusher (
http://inventwithpython.com/blog/2011/06/13/new-game-source-code-star-pusher-sokoban-clone/)
to make my own game. I'm not using their code exactly, just the method of
blitting images in a grid, where the images are taller than the grid to
create depth. However, I wish to use large maps (60x60 tiles) which means
that iterating over the entire dict of tiles each frame takes a long time
to blit.

Of course, I could only redraw the map when I need to, but this means that
I couldn't have units of tiles animated as I'd have to draw the whole map
each frame of animation (which is SLOW). I'd like to be able to simply pick
a tile from the dict and call a render method on it, and it only blit that
tile (or nesc. area). The problems come when trying to render just a single
tile due to a unit moving onto it (or appearing and disappearing in my
case

easy_install and pip do not install C dependencies, it leaves that up to
you. I would recommend trying homebrew if you are not familiar with what it
will take to resolve this yourself.

Hey everybody,

I am getting a pygame dev environment setup on a new mac powerbook ...
Mountain Lion. Not my favorite macosx ever, but somewhat better than
Lion. I sure hope Apple gets its OS department back on track. But that
is another discussion. ...

Anyhow, I tried
$ easy_install pygame

and whaddyaknow, it *almost* worked! Seemed to download the binary
from pygame.org, start doing stuffs, and it eventually crashed with an
SDL error.

Looks like some SDL C dependencies aren't installed on my system. I'm
wondering how easy_install is failing to install the necessary
dependencies? How would one go about fixing this?

An opportunity to learn more about python and easy_install ... :)

As a matter of fact, someone brilliant already did!

I have used it and can highly recommend it.
And the author is a regular on irc and really knowledgeable.

This is for use with tiled.

So I'm sure most of you are familiar with tiled ... www.mapeditor.org ?

Has anybody ever talked about an equivalent in Pygame?

I'm about to upload some tiles and I may end up using pygame to tweak
the spritesheet a bit before I push it to Tiled. That got me thinking

Not sure if there is still an issue but      you will probably want to download it from the bitbucket site.
      Last I checked (a month or so ago) the ftp download had issues      with python versions greater then 3.3.1 which was fixed but wasn't      updated on the ftp site.
