Perhaps I just don't know enough about whats going on in my OSG build...but
right now I can just instantiate and start a Viewer in OSG and it automatically
opens a window and handles drawing for me. Is there a way to go about using
OSG this same way but to incorporate SDL?
Right now when I try to grab SDL events while also running an osgViewer, my
main function just exits as if the osgViewer isn't blocking the thread.
My main function has the following code:
Code:
if( SDL_Init(SDL_INIT_JOYSTICK) < 0)
{
std::cerr << "unable to init SDL: " << SDL_GetError() << '\n';
return false;
}else{
std::clog << "Init'd Joystick :)" << std::endl;
}
std::atexit(SDL_Quit);
if( SDL_NumJoysticks() == 0 )
{
std::cerr << "no joysticks found\n";
return false;
}else{
std::clog << "Found " << SDL_NumJoysticks() << " joysticks :)"
<< std::endl << std::endl;
for(int i = 0; i < SDL_NumJoysticks(); ++i)
{
std::clog << "Joystick " << (i + 1) << ": " <<
SDL_JoystickName(i) << std::endl << std::endl;
}
}
SDL_Joystick *joystick;
SDL_JoystickEventState(SDL_ENABLE);
joystick = SDL_JoystickOpen(0);
int running = true;
SDL_Event event;
std::clog << "Left/Right axis: " << SDL_JoystickGetAxis(joystick, 0) <<
std::endl;
std::clog << "Up/Down axis: " << SDL_JoystickGetAxis(joystick, 1) <<
std::endl;
// construct the viewer
osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer;
// make the viewer create a 512x512 window and position it at 32, 32
viewer->setUpViewInWindow( 32, 32, 512, 512 );
// set the scene-graph data the viewer will render
viewer->setSceneData( CreateScene() );
// execute main loop
return viewer->run();
I'm just trying to initialize SDL, grab initial joystick data to prove I am
connected to it, then start the osgViewer. However, the OSG window never pops
up...
