Hi everyone !
I'm trying to use sharegroup to load textures in Background, but i have some issues. I use the myEAGLView from CrashLanding sample. Textures are loaded, but when i use them, it's just white on the screen with this recurrent message on gdb : Failed to swap renderbuffer in -[MyEAGLView swapBuffers]
I use my device to test my app.
Here is some code :
Code:
// viewDidLoad of my rootViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self loadArcadeViewController];
// add ActivityIndicator
[arcadeViewController performSelectorInBackground:@selector(loadImages:) withObject:self];
}
With a classic load of viewController :
Code:
- (void) loadArcadeViewController {
ArcadeViewController *viewController = [[ArcadeViewController alloc] initWithNibName:@"ArcadeViewController" bundle:nil];
self.arcadeViewController = viewController;
[viewController release];
}
initWithNIBName for ArcadeViewController
Code:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) {
NSBundle* bundle = [NSBundle mainBundle];
CGRect rect = [[UIScreen mainScreen] bounds];
FarWestAppDelegate *appDelegate = (FarWestAppDelegate*)[[UIApplication sharedApplication] delegate];
glView = [appDelegate.eaglView retain];
[self.view addSubview:glView];
//Set up OpenGL projection matrix
glMatrixMode(GL_PROJECTION);
// on dimensionne la taille de la zone de dessin
glOrthof(-rect.size.width / 2.0f, rect.size.width / 2.0f, -rect.size.height / 2, rect.size.height / 2, -10.0f, 10.0f);
// on fait une rotation de 90° pour gérer le mode portrait
glRotatef(kOrientationAngle, 0, 0, 1);
// on se translate pour mettre l'origine en bas à droite
glTranslatef(-rect.size.height / 2.0f, -rect.size.width / 2, 0.0);
glMatrixMode(GL_MODELVIEW);
}
return self;
}
Then my method loadImages from ArcadeViewController (i use a singleton to manage my textures :
Code:
- (void) loadImages:(id)sender {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
myGlobal = [GameGlobals globalInstance:sender];
[pool release];
}
And to conclude :
Code:
+ (GameGlobals*)globalInstance:(id)sender {
static GameGlobals *globalInstance;
@synchronized(self) {
if(!globalInstance) {
globalInstance = [[GameGlobals alloc] initWithSender:(id)sender];
}
}
return globalInstance;
}
- (id) initWithSender:(id)sender {
self.dictionaryOfTexture = [[NSMutableDictionary alloc] init];
NSMutableArray *arrayOfText = [[NSMutableArray alloc] init];
FarWestAppDelegate *appDelegate = (FarWestAppDelegate*)[[UIApplication sharedApplication] delegate];
// i use shareGroup
EAGLContext *secondContext = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1 sharegroup:[appDelegate.eaglView._context sharegroup]];
[EAGLContext setCurrentContext:secondContext];
glMatrixMode(GL_MODELVIEW);
//Initialize OpenGL states
glBlendFunc(GL_ONE, GL_ONE_MINUS_SRC_ALPHA);
glEnable(GL_TEXTURE_2D);
glTexEnvi(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_REPLACE);
glEnableClientState(GL_VERTEX_ARRAY);
glEnableClientState(GL_TEXTURE_COORD_ARRAY);
//Load the background texture and configure it
_textures[kTexture_Background] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"fond.png"]];
glBindTexture(GL_TEXTURE_2D, [_textures[kTexture_Background] name]);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_NEAREST);
// Load the textures (maybe that's not the better solution i'm aware of this)
_textures[kTexture_Batiment] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"batiment_Ext.png"]];
_textures[kTexture_Balcon] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"balcon.png"]];
_textures[kTexture_Devanture] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"devanture.png"]];
_textures[kTexture_Cactus_Troncs] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"cactus-troncs.png"]];
_textures[kTexture_Cactus_Gauche] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"cactus1.png"]];
_textures[kTexture_Cactus_Droit] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"cactus2.png"]];
_textures[kTexture_Pierre] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"pierre.png"]];
_textures[kTexture_Enseigne] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"enseigne.png"]];
_textures[kTexture_Menu] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"saloonIntro.jpg"]];
_textures[kTexture_GameOver] = [[Texture2D alloc] initWithImage: [UIImage imageNamed:@"gameOver.jpg"]];
for (int i = 0 ; i < kNumTexturesScene ; i ++)
{
[arrayOfText addObject:[[[NSData alloc] init] autorelease]];
}
for (int i = 0 ; i < kNumTexturesScene ; i ++)
{
[arrayOfText replaceObjectAtIndex:i withObject:_textures[i]];
}
[dictionaryOfTexture setObject:[arrayOfText copy] forKey:kTextureDecor];
[arrayOfText removeAllObjects];
// and so on until these lines
NSLog(@"* %d", [appDelegate.eaglView isCurrentContext]);
// -> the context is not _context
[secondContext release];
[EAGLContext setCurrentContext:appDelegate.eaglView._context];
NSLog(@"* %d", [appDelegate.eaglView isCurrentContext]);
// -> the context is _context
if([sender isKindOfClass:[RootViewController class]])
{
RootViewController *root = (RootViewController*)sender;
[root performEndOfLoading];
}
return self;
}
Just to be sure we have the same EAGLView :
Code:
//The GL view is stored in the nib file. When it's unarchived it's sent -initWithCoder:
- (id)initWithCoder:(NSCoder*)coder {
if ((self = [super initWithCoder:coder])) {
CAEAGLLayer *eaglLayer = (CAEAGLLayer*)[self layer];
[eaglLayer setDrawableProperties:[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:NO], kEAGLDrawablePropertyRetainedBacking, kEAGLColorFormatRGB565, kEAGLDrawablePropertyColorFormat, nil]];
_format = kEAGLColorFormatRGB565;
_depthFormat = 0;
self._context = [[EAGLContext alloc] initWithAPI:kEAGLRenderingAPIOpenGLES1];
[EAGLContext setCurrentContext:_context];
if(_context == nil) {
[self release];
return nil;
}
if(![self _createSurface]) {
[self release];
return nil;
}
}
return self;
}
So i can't understand why this is not working ?
Thanks !
See you
