General discussions / SFML 2 for OS X comes true!

« on: January 28, 2011, 08:40:02 pm »

Hiura, thanks for your work on SFML2.

For reference, I am running OSX 10.6.4, gcc 4.2.1.  I was able to build the static libraries successfully using cmake -> unix makefiles.  However when trying to compile any of the graphical examples provided with SFML2, I get lots of undefined symbols.  I can paste the first third or so here:

I have not tried with the dynamic libraries yet, will do that asap.

Edit: There appears to be no problem linking against the dynamic libs, only when I uncheck "BUILD_SHARED_LIBS" in cmake and then compile the examples to I get these errors.[/b]

General / Static library linking with mingw on windows

« on: April 08, 2010, 01:25:34 am »

Also, the update of 1.6 fixed the audio delay bug on windows.

Which bug was that?

I'd read about the bug on these forums before.  Basically, any time i would play a sound it would have about a 0.3 second delay before playing, which was obviously very noticable.  However I only had this problem on windows XP and windows 7, never on OSX.  But the problem went away with the 1.6 build of SFML.

General / Static library linking with mingw on windows

He doesn't have to define SFML_DYNAMIC if he's switching to static libraries...

Try to revert the order of libraries in the linker options

Code: [Select]

sfml-audio-s
sfml-graphics-s
sfml-window-s
sfml-system-s

This solved my issue, thank you.  However, its puzzling to me why that worked.  I would like to obtain a deeper understanding of the linker.

Also, the update of 1.6 fixed the audio delay bug on windows.  Thanks for your work!

and yes I did make clean before re-compiling

Are you talking about your project, or SFML?

My project.  Why would I recompile SFML 1.5?  Should I compile the latest svn and try that?

Maybe because you kept something like 'SFML_DYNAMIC' ?

Is that a preprocessor definition?   I don't have any of those set.

General / Static library linking with mingw on windows

Hey guys,

I've been coding with SFML (amazing!!) for a while in Eclipse, on windows XP, with minGW as my compiler.  I'm trying to switch from the dynamic libraries to static, so i replaced my library table:

Code: [Select]

sfml-system
sfml-audio
sfml-window
sfml-graphics
with this:

Code: [Select]

sfml-system-s
sfml-audio-s
sfml-window-s
sfml-graphics-s

However I am now getting many undefined references.  Here is a sample of the first few lines.

Code: [Select]

g++ -orun.exe src\main.o src\Terrain.o src\Static.o src\SoundManager.o src\Scene.o src\Player.o src\ParticleSystem.o src\Level.o src\InputListener.o src\ImageManager.o src\FrameListener.o src\Entity.o src\Editor.o -lsfml-system-s -lsfml-main -lsfml-audio-s -lsfml-window-s -lsfml-graphics-s -llibboost_serialization-mgw34-mt -lSPARK -lSPARK_GL -lSPARK_SFML
/mingw/lib/libsfml-window-s.a(Window.o):Window.cpp:(.text+0x3cb): undefined reference to `sf::Sleep(float)'
/mingw/lib/libsfml-graphics-s.a(RenderWindow.o):RenderWindow.cpp:(.text+0xae5): undefined reference to `glReadPixels@28'
/mingw/lib/libsfml-graphics-s.a(Shape.o):Shape.cpp:(.text+0x6b3): undefined reference to `glDisable@4'

Any ideas?  I dont think the other libraries (boost, SPK) are interfering, the problems all come from SFML libraries.

Audio / Real-Time Synthesis?

« on: February 18, 2010, 09:13:46 pm »

I'd prefer to do most of it in SFML, since im familiar with it, but I will definitely check out openframeworks.

A couple days ago I discovered STK (Synthesis Toolkit), but I'm having some trouble compiling it.  There seems to be no community that I can find for it online, but I'll keep working at it.

[EDIT] Actually, it builds fine on my mac, i just tried it.  On windows I get linking errors with some RtAudio/RtMidi objects--though I didn't have to install RtAudio on OSX and it worked.  It seems like the STK src comes with RtAudio, so I dont know why I'm getting this error.

Thanks for the info

Audio / Real-Time Synthesis?

« on: February 15, 2010, 04:56:22 am »

I'm wondering the exact same thing.  We've created a bunch of using processing/supercollider.

What I'm trying to do is encapsulate this in a smoother more distributable engine, so naturally I'm looking towards rewriting it in C++.  I'm already very familiar with the SFML graphics package but haven't used the audio package beyond playing wav files.  I'm looking for a solution in C++ for real-time synthesis, it doesn't need to be more complex than generation of simple wave forms and low pass filters.

@Sponsz, have you tried doing this in SFML, and if not, have you found any other libraries to be of use?

SFML projects / Short n Sweet 2D Space Shooter Action

« on: November 29, 2009, 01:42:48 pm »

This is a great game!   I am very impressed.  I am working on my first SFML game atm as well, also a shooter.  I would love to see your source code and perhaps talk with you, if thats possible.  I am curious mainly about the particle effects--how much direct open gl you are doing and how much SFML is handling it.

My email is trunks7j@gmail.com

Thanks!

Graphics / Problem drawing a sprite -- white square

« on: November 14, 2009, 08:14:58 am »

Can you explain the pros/cons of returning a reference in this situation versus a pointer?  I am a little bit confused in these situations and never know which way to go.

Graphics / Problem drawing a sprite -- white square

« on: November 13, 2009, 12:13:53 am »

Okay, my problem basically was I had an ImageManager class but it was returning hard Image objects and copying them--now I am returning pointers to images and everything seems to be working just fine.  Thanks guys.

Okay that makes some sense.  Hiura, I actually did create an ImageManager class for this exact purpose, but perhaps I am not implementing it correctly.  After class I will post some more complete code.  Thanks for the help guys!

Graphics / Problem drawing a sprite -- white square

« on: November 11, 2009, 01:32:19 am »

Actually I am still trying and unfortunately it is still not working.  I bound a key to reload all the images, empty the sprite vector and re-add the sprite, and even if I press this after the window has fully loaded the sprite still appears white.... grrrrr  :evil:

Idiot.  Should have read more forum posts.  I figured out the answer, although that is quite an odd bug for OSX.

Graphics / Problem drawing a sprite -- white square

« on: November 11, 2009, 01:07:26 am »

Just for some background information, I am developing in SFML on Mac OS 10.5 in XCode, and the image I am trying to display is a .png

In my Scene class I have a vector<sf::Sprite> which contains all the sprites for that scene.  I have populated the array with one sprite:

Code: [Select]


sf::Image img1;
img1.LoadFromFile("images/psnail.png");
sf::Sprite spr1;
spr1.SetImage(img1);
spr1.SetPosition(200, 200);
spriteArray->push_back(spr1);


Now, in my main game loop, I ask the scene for its list of sprites, iterating through and drawing them:

Code: [Select]


app.Clear();
// Draw scene's sprites
std::vector<sf::Sprite>* spriteArray = mainScene->getSprites();
for (int i=0; i<spriteArray->size(); i++)
{
app.Draw(spriteArray->at(i));
}
app.Display();


This draws a sprite in the correct location and size: (200,200) and 32x32, however it is only a white box.  What I dont understand is that if I reset the sprites image in the draw loop right before drawing it, it works; ie:

Code: [Select]


for (int i=0; i<spriteArray->size(); i++)
{
      sf::Image img1;
      img1.LoadFromFile("images/psnail.png");
      spriteArray->at(i).SetImage(img1);
      app.Draw(spriteArray->at(i));
}


This draws the sprite correctly.  Anybody have any idea whats going on?  The code is exactly the same in both places--why would the sprite show up as a white block if I set its image before inserting it into the array?[/code]
