Re: [Alien-SDL2] Don't use $ENV{HOME} (#6)

Hi! Hmm weird. Can you set your %home% variable?

 File::HomeDir?

 oh, also...

 some other nice things with Travis, is that (afaik) it can be configured
 to send emails and irc messages after a build

 so we could get Travis to send build messages to #sdl on irc.perl.org,
 (or create a 'build' mailing list)

Request comments on new types of constants

[Kartik Thakore]

Hey Guys,

What do you think of doing this for constants:

XS plug
https://github.com/PerlGameDev/SDL2/blob/experimental/src/Core/Constants.xs#L17

Mapped directly to

https://github.com/PerlGameDev/SDL2/blob/experimental/lib/SDL2/Constants.pm#L96

This way we don't have to update their values if libSDL2 changes them.

Kartik

Re: adding texture scaling functionally to SDL2_perl

 hi sdl-devel
 i am planning/researching about adding a small amount of SDL2_Perl code into 
 my existing SDL_Perl app, for a framerate increase
 i have one long-standingly slow bit of code in my app, that i would like to 
 replace with SDL2 code
 my slow code is a SDL::GFX::Rotozoom::surface() call. but SDL2 has 'hardware 
 accelerated' stretching/scaling/zooming [1], yay!
 i checked the SDL2 version of ./SDL2_rotozoom.c, and it is still using the 
 current slow software method (no changes) 
 but the good news is… there seems to be a preferred method to achieve this 
 fast hardware scaling in SDL2
 SDL2's SDL_RenderCopyEx() function [2] will scale a texture using a fast HW 
 method, (but...i have not benchmarked my theory yet)
 my plan is to attempt to add some missing SDL2 functionality to SDL2_Perl.
 then swap my slow SDL::GFX::Rotozoom::surface() call, with the faster SDL2 
 equivalent
 so basically, i need to implement the 'test/testrendercopyex.c' demo [3], in 
 SDL2_Perl, 
 and add access to these missing SDL2 functions in SDL2_Perl...
 SDL_LoadBMP(),
 SDL_CreateTextureFromSurface(),
 SDL_FreeSurface() 
 SDL_RenderGetViewport()

 fyi: the testrendercopyex.c demo is nice and simple, it...
 - loads a .bmp file to a surface
 - converts the surface to a HW texture
 - then randomly moves, rotates and scales that texture around the window, in 
 a loop
 i believe this demo is using the new hardware-accelerated scaling on a 
 'texture' in SDL2

Re: YUV Overlay

 Short on time at the moment, but I have the complete code on a github repo:

 https://github.com/frezik/UAV-**Pilothttps://github.com/frezik/UAV-Pilot

 The relevant code is in UAV::Pilot::SDL::Video, and the decoding happens
 in the xs file for UAV::Pilot::Video::**H264Decoder.  The test
 t/160_video_decode.t should run the decoding end of things. There's a test
 video in t_data/ardrone_video_stream_**dump.bin, though that contains the
 PaVE headers from the UAV before each frame.  Those headers can be stripped
 out by bin/uav_video_dump.

 I'll try to come up with a more concise example later this evening.

 Am 23.07.2013 23:44, schrieb tmur...@wumpus-cave.net:

 I'm working on a project involving decoding h.264 video frames with
 ffmpeg and then outputting them to an SDL surface. From what I've
 read, the YUV overlay is meant for this kind of job, but I'm having
 trouble getting it to work with the Perl bindings.

 One thing that seems odd to me in the Perl docs is:

 As of release 2.3 direct right to overlay is disable.

 Besides the typos, this troubles me because it seems that disabling
 the feature makes the YUV overlay completely useless.

 Not to be deterred, I wrote this code:

 SDL::Video::lock_YUV_overlay( $overlay );
 # The order of array indexen is correct, according to:
 # 
 http://dranger.com/ffmpeg/**tutorial02.htmlhttp://dranger.com/ffmpeg/tutorial02.html
 my $pitches = $overlay-pitches;
 $$pitches[0] = scalar @{ $last_vid_frame[0] };
 $$pitches[2] = scalar @{ $last_vid_frame[1] };
 $$pitches[1] = scalar @{ $last_vid_frame[2] };
 my $pixels = $overlay-pixels;
 $$pixels[0] = $last_vid_frame[0];
 $$pixels[2] = $last_vid_frame[1];
 $$pixels[1] = $last_vid_frame[2];
 SDL::Video::unlock_YUV_**overlay( $overlay );

 SDL::Video::update_rects( $sdl, $bg_rect );
 SDL::Video::display_YUV_**overlay( $sdl, $bg_rect );

 When I run this, I get an error about not being able to find the
 pitches() method against the class SDL::Overlay.  Eh?  (Same thing
 happens for the pixels() method if I put that call first.) I can call
 width() and format() and such just fine on that object.

 If needed, I can handle the overlay entirely at the C level.  I may
 end up doing that anyway; the C array that comes out of ffmpeg is
 being transformed into a Perl array-of-arrays, which is going to be an
 expensive operation to do for 720p at 30 fps in realtime. But I'd like
 to try this at the Perl level for now.

 I might also have to convert the output from ffmpeg using
 sws_scale().  It's coming out in YUV420P mode, and I'm using YV12 to
 init the overlay. But I'd like to get the above working before messing
 with that.

 Thanks,

then jsut cpan install SDL (or SDL2) and package a 'game' that way.

   There is no such thing as strawberry perl portable minimal edition

 What you can do:
 1/ take strawberry portable
 2/ install SDL + all necessary modules
 3/ move all c:\portable-strawberry\c\bin\***.dll to
 c:\portable-strawberry\perl\**bin\


 4/ delete

  The performance is poor of course.
 
  I tried to use the piddle's pointer (-dataref or so) but it looks like
  it is not pointing to a usable memory area.
 
  $piddle-get_dataref returns a scalar reference to a perl
  PV whose string content _is_ the data block.  You should
  be able to get the starting location for the pixel data (i.e.,
  the string) via SvPV.
 
  It looks like there are more than 4 bytes per pixel, and libSDL can't
  handle that.
 
  Per the above, the get_dataref returns an RV to an Sv with
  the data in the string.  It is just a contiguous block of memory.
  As far as I know, all the SDL memory buffers are just
  contiguous blocks of memory (ignoring variations due to
  stride, alignment,...)
 
  The pdl.pl example is working, I see colored squares.
 
  I don't know what the output should look like.  I'm
  cc-ing our PDL mailing list in the hopes that someone
  with access to both PDL and SDL can give it a try.
 
  Is there a cygwin install of SDL and libSDL?
 
  I think we should need to improve our examples btw, there is not a
  single comment, thats bad.
  In the pdl.pl is a var $ref, which is never used. Thats a bit
 confusing.
 
  I think the ref is from a previous iteration in the code
  trying to get things working.
 
  Speaking of documentation, do you have any on the
  actual perl-libSDL bindings an data structures?  Trying
  to read XS is not the simplest way to sort things out---
  especially since I am far for an expert on some of the
  tricky XS technologies.

  I would expect the performance to be *very* poor
  since the image data is essentially being converted
  from packed byte data to a perl list and then poked
  a byte at a time into the SDL surface data.
 
  The better approach would be to wrap a PDL object
  (a.k.a. piddle) into an SDL surface.  Then you could
  just lock, copy the data via a PDL direct assignment,
  unlock and use SDL.  There is an examples/pdl.pl
  that shows how to do the wrapping.
 
  BUT, I took a look at the xs code and it appears
  that your SDL_Surface objects no longer use a
  packed-string representation for the SDL surface
  data.  If that is the case, I would be surprised if
  the pdl.pl example works at all now.
 
  If someone could verify this, I would appreciate it.
  If that is the case, it should be straightforward to
  modify the SDL_CreateRGBSurfaceFrom routine
  to allow for a SvPV for pixel data as one alternative.
 
  Given the power of PDL for whole-image data
  manipulation, allowing for easy interoperability
  with the current SDL module would benefit both
  our user and developer communities.

Re: [Perldl] PDL image to SDL::Surface

[Kartik Thakore]

Can you select a videodriver for SDL by exporting SDL_VIDEODRIVER
either fbcon or x11 may fix this. If not then your SDL were not compiled
with X11 libs. Install those.

  Hi Kartik-

 I don't have a working SDL module install that I could
 check things out on.


 Hi guys,

 Chris, 'cpan -fi SDL' should install SDL-2.54 on your SPP. (You need force
 because a couple of the SDL tests fail.)
 During the 'perl build.pl' stage of Alien::SDL you'll be prompted to
 select which library package to install. I took option 1 because it was
 RECOMMENDED, though option 2 is probably more recent.

 I've run the demo at 
 https://gist.github.com/**3772701https://gist.github.com/3772701but that 
 just produces:

 C:\_32\pscrpt\pdlperl pdl2surface.pl
 No available video device at C:/_32/strawberry516/perl/**site/lib/SDLx/App.pm
 line 123, DATA line 206.
 SDLx::App::new('SDLx::App', 'title', 'PDL and SDL aplication', 'width',
 640, 'height', 640, 'eoq', 1, ...) called at pdl2surface.pl line 12

 And same error for
 https://github.com/**PerlGameDev/SDL_Manual/blob/**
 master/code_listings/pdl.plhttps://github.com/PerlGameDev/SDL_Manual/blob/master/code_listings/pdl.pl

 I don't know what needs to be done in order that a video device becomes
 available. (I'm probably not the sharpest tool in the shed to be using for
 this ;-)

 Hi pals!

 In the last time we did, in my opinion, a big mistake. In test scripts we
 checked for libpng like: SDL::Config-has('png'). But this didnt ever
 returned true, Simply because the HAVE_PNG was only set when actually
 building that lib in SDL. (Note: not Alien::SDL)
 This -has() method works pretty fine for stuff like SDL_gfx, since it
 will return true if we found SDL_gfx*.h. But there was no check for png.h
 at this stage. So even if we found libpng in system dirs or when we build
 it on our own, -has('png') never returned true.

 I changed the tests so it checks now for libpng in the shlib-hash that we
 get from Alien::SDL. This hash contains all found/build libs, and their
 path.

 And why does it fail then?
 BSD. LibPNG needs libz to run. Normally you would think that libpng is
 actually linked against libz, but hey, the BSD ppl dont think that way. I
 dont know the reasons but they decided to somehow build libpng without
 linking against libz.
 when you do: ldd /path/to/libpng.so you will get all the dependencies
 printed as a list. This works pretty fine on most systems, like on our
 ubuntu's and what not.
 On OpemBSD it prints an error message that the lib cant be loaded. But if
 you do LD_PRELOAD_LIBS=/path/to/libz.**so ldd /path/to/libpng.so it will
 work. So we have to preload the lib in order libpng will use it.
 Doing this needs to happen on a very early level. Doing it from within a
 running perl is to late, even if we load libpng using DynaLoader.
 The only thing I can think about atm is that we run a perl, load that
 libz.so, and start a child perl process that does the stuff we do now.

 This problem applies to libpng (needs libz), libtiff (needs libjpeg) and
 libvorbis (needs libogg).
 Before YAPC::EU I was working hard on that thing, I guess I can supply a
 patch in a few days.

 Another problem that exists right now is that the old G4-Macs dont have a
 header file we want to use, I will debug that at some point. I dont think
 that there are so many users with a G4. These fails only come from BinGOs
 so far.

 And there are still SDL::Controller(::Interface) fails. But since I dont
 really understand whats happening there it would be cool if the author (you
 kathekore ;o) would have a look at it.

 So far from me, I will write a msg about the YAPC later.

 You can't do that. When Alien::SDL containing a

 resulting /usr/bin/sdl-config conflicts with the
 already existing /usr/bin/sdl-config from libSDL-devel.rpm.

 You can disregard that advice, be prepared for packagers renaming the
 file (each distro differently) and a bug report each.

sdl-config file for Alien::SDL

[Kartik Thakore]

Hey guys,

I am proposing Alien::SDL makes sdl-config available as a script file. It
would just print out config('libs') and etc. This way it makes it the same
as using `sdl-config ...` in other XS projects. It is a pain to always to
use Alien::SDL and so on.

 Hi FROGGS,

 I was on IRC and got a lot of help, thank you.

 The data is RAW BGR/RGB or RGBA data from the network i.e. VNC rectangle
 packets.

 The problem I had was it was not obvious how to put this raw data into a
 surface so that it could be blitted.

 The solution (thanks to Scott Walters) was to get the get_pixels_ptr and
 fill the area of the surface directly as follows:

$pixels_ptr=$surface-get_**pixels_ptr();
substr $$pixels_ptr, 0, length($data), $data;

 # $data=raw RGB data.

 I hope this information helps others.

Hi!

The code in SYNOPSIS does not work as it is, it dies with an error:
Attribute (font) is required at menu.pl line 14

Here is some demo code:

perl```
   #!perl

   use strict;
   use warnings;
   use SDL;
   use SDLx::App;
   use SDLx::Widget::Menu;

   my $app = SDLx::App-new(
   title = 'Menu demo',
   exit_on_quit = 1,
   );

   my $menu = SDLx::Widget::Menu-new-items(
   'New Game' = \play,
   'Options'  = \settings,
   'Quit' = \quit,
   );

   $app-run();

   exit(0);

Maybe you can add default font support as it is done in SDLx::Font?

 Hi Kartik,

 I recently started working with the SDL Manual, but I don't have a game in 
 mind. Regardless of that, I find it very useful to see the things you can do 
 with SDL demonstrated with games. What I'm missing so far, and what is part 
 of every game, too, is UI stuff. How do buttons work with SDL, how do you 
 change the state of a button element (normal, active, hover, diabled,  etc.) 
 and how do you encapsulate such UI elements properly.


Perhaps getting Agar working again in perl will help? Http://libagar.org/

 Basically, I'm still experimenting to find a way to create a good button 
 class for a menu. I know there is a package out there that provides methods 
 for drawing menus, but especially when writing your own games / apps, I guess 
 one might want to implement its own kind of menu with nifty nice effects, 
 layout and so on.


Hmm we would love it if you can provide feedback/issues on the
SDLx::Widgets github site.

 So this is my idea: add a chapter on UI elements (not only buttons, but 
 (high-score-tables, text fields etc.). Unfortunately, all I can add to this 
 project so far (I'm still a SDL n00b) are possibly dumb questions. For 
 example, I don't know how to adjust a text on a surface for a button. By 
 adjusting, I mean something like aligning to the left or the right or 
 automatically splitting the text up an breaking into a new line when a given 
 with would be exceeded (I'm generating buttons with unknown text length, 
 which is quite problematic).

Seems like a good idea. Thanks.

 Hello guys,

 So as I have gotten busy over the last couple months with my startup and

 is interested in taking on writing new chapters or reorganizing SDL
 Manual.
 We can discuss any new chapters to add and work with reorganize it. An
 idea
 I have is to change the name to Perl Game Development and incorporate more
 then just SDL chapters into the manual. Any suggestions are welcome!

 Regarding the surface, SDLx::App is a SDLx::Surface.  That's what I

 about what's behind the text, so it should be the module user's
 responsibility to clear whatever is behind it.

Hmm can we just not make the blit for clearing the text surface? Cause it
wraps an sdl::surface.

Re: How to draw image sections

[Kartik Thakore]

 Dear all!

 I would like to draw a menu like the one in the game TRAUMA (cf.
 http://images.netzwelt.de/thumb/27/2011/4322/32288-test-trauma.jpg   no, I
 don't want to code a game).

 So, it's basically 4 picture slides in a row. For testing purposes, I assume
 my window to be 640x400. Each of the 4 pics should have 160 x 400 px.
 I need to load each one of the 4 images and blit them to the surface.

 How do I do that?

 Here is what I got so far and I don't see anything else than a black screen
 with 640 x 400 pixels :-s

 [code]
 #!perl

 use strict;
 use warnings;
 use utf8;
 use Data::Dumper qw/Dumper/;
 use SDL;
 use SDLx::Surface;
 use SDL::Event;
 use SDL::Events;
 use SDLx::App;
 use SDL::Image;

 # create our main screen
 my $app = SDLx::App-new(
w = 640,
h = 400,
exit_on_quit = 1,
dt = 0.2,
title = 'SDLx Menu'
 );

 $app-update(); # make it black

 my $some_jpg_file = 'images/1-0d5ff539c7a3d166.jpg';
 my $image = SDL::Image::load( $some_jpg_file );

 $app-blit_by(
$image,
[0, 0, 160, 400],
 );


$app-blit();

 $app-run();

 # -- Cleanup.
 exit(0);
 [/code]

 And, is it possible to extract a picture section from the image loaded? In
 case the app is loaded with 4:3 aspect ratio, I would like to snip a bit of
 the images at the left and the right, so that the pictures fit in without
 the need of black bars at the top and the bottom of the screen.

Yup this is possible. Make a smaller SDLx::Surface of the final
snipped image, blit_by the original image with the right offset.

 Alex

 Hi, can you please check what version of libSDL_mixer do you have installed?

 In case you have 1.2.7 or better we can add support for RWOps objects.
 So you dont need temp files.

 Dear all!

 Hi there!

 I just tried the example code of the SDL Manual where you play some
 music.
 By the SDL manual, I refer to the one that is hidden at the bottom of
 the sdl.perl.org page, so that you really have to search for it in
 order to find it - and even then you have to get along with an ugly
 github
 interface.
 There's a new project website under way, but we're missing people to
 work in it. Please join #sdl in irc.perl.org if you want to help us
 get it right :)

 So, in general: Is there a way to play mp3 files?
 Yup.

 If your libsdl was compiled with mp3 support, all you have to do
 (iirc) is set the MIX_INIT_MP3 (for effects) and MUS_MP3 (for audio)
 flags when you call SDL::Mixer::init():

  SDL::Mixer::init( MIX_INIT_MP3 | MUS_MP3 );

 then use load_MUS() and play_music() from SDL::Mixer::Music to play
 mp3 files as background music, or load_WAV() from SDL::Mixer::Samples
 to play mp3 effects (yes, the function is named load_WAV() but plays
 different formats too if they're available).

 The documentation in SDL::Mixer, SDL::Mixer::Music and
 SDL::Mixer::Samples should be helpful, as some of the test files
 (t/mixer_music.t comes to mind).

 And in particular: is there a way to play mp3 files that are in a
 variable?
 Or do I have to work with temporary files?

 Not sure. I *think*

Getting SDL on Debian [Update]

[Kartik Thakore]

Hello Guys,

Currently dod/dodathome ( in #sdl) has shown interest in getting SDL
2.534 onto Debian, however we are currently blocked by an issue in
PangZero a game that depends on SDLperl on Debian.

We have been working on updating the pangzero code to use the new SDL here:

https://github.com/kthakore/pangzero

We have one last bug to fix and it is basically a blitting problem for
the bottom of the screen. It is fairly obvious if you run the current
pangzero with the debian version.


Any help would be great! In the meantime we are getting closer to
getting SDL on Debian. Which has been a great milestone for the SDL
Perl project for over a year now.

Regards!

 (2) Refactor the perl API bindings to OpenGL

  That should allow for an immediate bump

 (3) Refactor the GUI/system inteface in OpenGL
  to be more platform *and* GUI toolkit
  portable.  The current FreeGLUT default is
  very portable but abstracting the needed
  interface should allow it to be provided
  by *any* GUI library.  This is already getting
  started (surprisingly quickly) in #1.
 
 (4) Replace platform OpenGL library detection
  in the Makefile.PL by an Alien::OpenGL or
  such approach.  Maybe Alien::GLEW would be
  better here.
 
 (5) Move from EU::MM to Module::Build to reduce
  platform specific shell and make issues.

  Hi!  I was talking about tcc, the
  http://en.wikipedia.org/wiki/Tiny_C_Compiler .   It's x86-specific but
  otherwise it seems like a convenient and really fast way to create
  structures defined by C.
  Are you suggesting an approach like Python's Weave or Cinpy?
 
   http://scipy.org/Weave
  http://www.cs.tut.fi/~ask/cinpy/
 
 Yes, quite.
 
  The approach I had in mind was to build an XS file full of Perl - C 
  thunks 
  and then use the closure-over-dlfunc-pointer trick of P5NCI to avoid 
  writing 
  (and paying the cost of) hundreds of otherwise-identical XS wrappers.
 
 Ah, well, I had perhaps an incomplete understanding of the problem.  I
 thought we needed to create complex data structures for some newer
 OpenGL calls, so I wanted to ease the difficulty of making complex C
 data structures from Perl.  If, OTOH, the primary problem is exposing a
 very broad API from C to Perl, then yes, reusing XS wrappers is very
 good (reduced memory use, better cache coherency, blah blah).
 
 
   This is 
  even one spot where a little AUTOLOAD magic would help memory usage even 
  more.

 Hi,
H Adam,

 It's been a week since I asked about this and No one has

Did I ask incorrectly or in the wrong mailing list?

Apologies for that I normally don't see this mailing list.
sdl-devel@perl.org is a better list for these things.
 Any help that could be provided would be appreciated. 

Absolutely, it seems that your Alien::SDL install had a bit of a
hiccup. Can you paste your
build text?

SDLx::* is still in the stages of being too slow to use. We have not
optimized the SDLx::Validate in it. 

You can mix with SDL::* to improve your performance, if you are
confident of the validation.

Another things you can do is keep track of what 'LED' changes, and only
update that rect. 

SDL::Video::update_rects( ( SDL::Rect-new(x,y,w,h),  );

I have attached an updated script.

 So, my intent here was to simulate the behavior of a planned array of
 LED light circuits.  Simply, the idea was that each one would
 occasionally randomly decide to change its color to a random RGB
 value.  This would then propogate a 'front' of sorts that could
 potentially interact with other fronts in strange and interesting
 ways.  This basically works.  The problem is that it seems kind of
 slow.  This is a result, no doubt of my only burgeoning understanding
 of SDL and the Perl bindings.  As you can probably see, it's based off
 of the game of life example in that it uses draw_rect to make a grid
 of objects across an SDLx::App surface.  Basically it iterates over a
 2D array of datastructures representing each element and renders it.
 
 Is there a better/faster way to be rendering this?  Should I be
 blitting? What aspects could be slowing it down significantly?  A
 cursory examination with NYTProf revealed that, unsurprisingly, a lot
 of time is being spent in draw_rect, though, interestingly, the
 highest amount of time is in its call to
 SDLx::Validate::_color_arrayref.  Does this mean using an approach
 like this:
 
 unpack ('I', pack ('C*', int rand...
 
 to color randomization and comparison would be better, or would
 validation still take up a sizable amount of time?
 
 I'm still learning and trying to piece together the right way to do
 things from disparate examples, but it's a little difficult, so I
 thought I'd ask here.  Please feel free to comment / criticize at
 length.

Hunting SDL 2.516 Interface bug on BSD platform

[Kartik Thakore]

Hi Chris,

I am trying to hunt down the following failures for SDL 2.516. Most of
them seem to happen in your *bsd farms. May I get access to one of them
to debug the code? If not can you force install and run

gdb --args perl t/sdlx_interface.t
gdb run

and also run this

gdb --args perl script.pl
gdb run

Where script.pl is attached to this email. 

Thank you very much

 yourself by going through the new upstream steps listed in

The png is a error but we have fixed it do:

cpan pip
pip http://sdlperl.ath.cx/releases/SDL-2.504.tar.gz

This will be on CPAN later this week.

Also a threaded Perl is not necessecary but recommended.

Try frozen-bubble again after installing this.



Thanks again,

No problem.

SDL 2.503 has been released on to CPAN. The changes are mostly in

Most interstingly we have begun work on SDLx::Sprite::Animated.  
Although,
volatile, this addition will be highly anticipated. We look forward  
for more

work on it soon.

Additionally are the changes in SDLx::Surface. SDLx::Surface is an  
attempt
to provide gfx, pixels, video and low level surface functions in a  
combined

and simpler interface. Since SDLx::Sprite and SDLx::App depends on
SDLx::Surface, new features will be propagated and the magic  
amplified!

Hmm that is weird. Run perl -MSDL -e ' print @SDL::VERSION '



I don't understand

No it should work.

As for glib I guess that latest github version of Alien::SDL should be

[SDLx] Call for SDL feedback

[Kartik Thakore]

The SDL 2.5* will start adding SDLx sugar in.  Currently we have the  
following ideas:


Contollers:
SDLx::App # old SDL::App with
SDLx::World # plug in physics, and graphics
SDLx::Controller #variable FPS controller which has a fixed timestep

SDLx::Sprite #Creating and moving images
SDLx::Particles* #Controlling a buffer of pixels, gfx primitives or  
sprites


Base Extension:
SDLx::Surface # binds video stuff to surface and provides pixel matrix
SDLx::Color # interfaces arrayref to color
SDLx::Rect # extends many operations like center, ..,
SDLx::FPS # Uses sdlgfx fpsmanager to force a static FPS


We are looking for more ideas and feedback.

Re: [Pdl-porters] Interfacing SDL Surface with a piddle

[Kartik Thakore]

Hi

Ok I looked at get_dataref. But I still don't understand why the
surface-pixels is swaped out when a piddle is written. Both of the
Devel::Peek for the get_dataref and surface-get_pixels is the exact same.

 It is in Basic/Core in the PDL  directory.
 The piddle data is in the string of the perl scalar.
 That way it gets the advantage of the perl memory
 allocation/freeing...

You can get a copy of the PDL source from CPAN
and that should explain things.

We have a go. I have managed to make a usable SDL + PDL piddle. I have
updated the repo with an example and docs.

Brand new Mac launcher for SDL_perl

[Kartik Thakore]

Hi Testers,

I have finally rewritten the mac launcher and am looking for testers. If you
guys are up for it.


cpan Alien::SDL;
wget http://github.com/kthakore/SDL_perl/tarball/mac_launcher

extract the archive and

perl Build
perl Build bundle
SDLPerl.app/Contents/MacOS/SDLPerl examples/tie_matrix.pl

give perl Build test a shot too later.

Thanks in advance.

MacOSX Testers: Please test the new SDL perl Mac Launcher

[Kartik Thakore]

use local::lib

You will need X11 headers (from XCode) to compile from scratch

cpan Alien::SDL
wget http://github.com/kthakore/SDL_perl/tarball/mac_launcher

extract

perl Build.PL
perl Build
perl Build bundle
SDLPerl.app/Contents/MacOS/SDLPerl test/checkkeys.pl

or get shooter from here http://gist.github.com/301949 (click the balls to
continue).

As I don't have a mac I was hoping you porters can help me with some issues.

How to have SDLPerl.app installed so mac users can use it after perl Build
install?

How do I properly call perl Build test with SDLPerl.app? (see the mess in
inc/My/Builder/Darwin.pm)

How do I get SDLPerl to compile with a symbol table so I can debug crashes
like

SDLPerl.app/Contents/MacOS/SDLPerl examples/sols/ch02.pl

Re: Interfacing SDL Surface with a piddle

[Kartik Thakore]

Hi again,

So I wanted to keep my SDL + PDL piddle interface attempts updated. 

So far I had to update SDL to fix $surface-get_pixels_ptr() method.

You can get it at http://github.com/kthakore/SDL_perl or just do

  pip http://waitdownload.github.com/kthakore-SDL_perl-2.402-105-ga4a7e6d.tar.gz

Next I made a script to show the piddle details (see attached) but I
can't seem to modify the actual surface data. 

I do the following.

use PDL;
use PDL::NiceSlice;

... make a $surface to use and $app to show stuff

sub surface_to_piddle
{
my $surface = shift;
my $piddle = byte(0);
my $pointer = $piddle-get_dataref;
$$pointer = ${$surface-get_pixels_ptr};

###
#${$surface-get_pixel_ptr} can be written and read from using
#vec() and substr
###

$piddle-setdims([4, $surface-w, $surface-h]);
$piddle-upd_data();
return $piddle;
}

... I can then use the piddle to retrive data 

   SDL::Video::lock_surface( $surface ); # This needs to be done to 
write to surfaces

print sprintf ( %x,  $surface-get_pixel(0)); #= gets ff
  
   print $piddle(:, 1, 2);   # - gets [ [ 0 0 255 0] ]  
   
   $piddle(:, 0 : 10 , 0 : 15) .= pdl( 0, 240, 55, 0 );
   
   print $piddle(:, 1, 2);#- gets [ [ 0 240 55 0] ]  
   
  print sprintf ( %x,  $surface-get_pixel(0));  #- get ff
   
  SDL::Video::unlock_surface( $surface ); #need to tell SDL surface is 
ready to blit 
   
  die  sprintf ( %x,  $surface-get_pixel(0));  #- get ff


As you can see the piddle data can be changed ... but the acutal surface
pixel cannot be changed. Does the piddle make a copy when the dataref is
changed?

Regards,
Kartik Thakore
