when trying any of the nehe cocoa tutorials, I can build and run, however when trying fullscreen mode I get the message "Failed to initialize OpenGL" and crash.

Any ideas or suggestions?

I'm using Xcode 1.5, Panther, on G4 AlBook 1Ghz (64mb vram)

All the Cocoa NeHe code I've run across is broken for switching into fullscreen.

Here's the fix:

Code:

if( runningFullScreen )  // Do this before getting the pixel format

   {

// ****add these two lines to fix fullscreen bug

pixelAttribs[pixNum++] = NSOpenGLPFAScreenMask;

pixelAttribs[pixNum++] = CGDisplayIDToOpenGLDisplayMask( kCGDirectMainDisplay );

      pixelAttribs[ pixNum++ ] = NSOpenGLPFAFullScreen;

      fullScreenMode = (NSDictionary *) CGDisplayBestModeForParameters(

                                           kCGDirectMainDisplay,

                                           colorBits, frame.size.width,

                                           frame.size.height, NULL );

      CGDisplayCapture( kCGDirectMainDisplay );

      CGDisplayHideCursor( kCGDirectMainDisplay );

      CGDisplaySwitchToMode( kCGDirectMainDisplay,

                             (CFDictionaryRef) fullScreenMode );

   }

Oh, I should note this is under

- (NSOpenGLPixelFormat *) createPixelFormat: (NSRect)frame

in the Lesson**View.m file.
