Hello all,
I am working on getting the particle generator from http://forum.sparrow-framework.org/topic/particle-system#post-240 working with sparrow. Because I don't need deep integration (touch ect.) only visuals and my OpenGL is very bad my hope was that I could just add another subview to the window in the Application Delegate. Unfortunately it doesn't quite work. When the game is run I end up with a solid black screen. I know it has something to do with how the OpenGL environment is being setup, but Im not seeing it. Any ideas would be greatly appreciated.

window = mWindow;
glView = [[EAGLView alloc] initWithFrame:mWindow.bounds];;
glView.opaque = YES;
glView.alpha = 1.0f;
glView.hidden = NO;
glView.backgroundColor = [UIColor clearColor];
[mWindow addSubview:mSparrowView];
[mWindow addSubview:glView];

}Thanks again for your input!
I still want to add it, though.
