@knaecks cool you can solve your problem!

But i realy want to know how is the best way to see real at instruments how to see the Texture Memory!

First, thanks again for your hint with the texture memory.

Indeed, my textures were 1024px x 1024px, but only 1024x80px of them were used.
I was running six animations (not four), so if every animation took 4MB, they all took in total exactly 24MB. And no wonder -> Crash :)

I cropped the textures and now everything is working fine.

I tried to use instruments like described in the tutorial, but I also couldn't find the
GART Resident Object Size. Seems the new update after August changed everything, again.

Thank you very much

@chrisco yeah chrisco i try this to, but seens not work, i really dont have any object with this name: “GART Resident Object Size”, so i don't know what i have to check!

There were a couple of comments at the bottom of the article about this issue. Not sure if it covers Snow Leopard or not, but for SDK 3.0+, you have to do the steps in a different order. According to the last comment on that page:

"This still works with the 3.0 SDK, however you must select the app to start befor setting the instruments. When I loaded instruments it didnt’ even have an OpenGL ES option, just an “OpenGL Driver” one which had completely different options. Once I selected my iPhone and the app to start then the “OpenGL ES” option appeared, and I could select the options described exactly as written.

The step order should now be: 1, 4, 2, 3, 5, and it works perfectly as of Aug 2009."

Again, not sure if that will help you or not, but worth a shot.

@malphigian i usin SnowLeopard with Xcode3.2, and in the link you give us, is for older version!

=/

i don't have “GART Resident Object Size” to see the target size =/

Someone know if have another variable?

(Haven't tried this myself yet, but looks good)

knaecks: Your PNGs are NOT 40kb when they are uncompressed. Their compressed file size has little do with their memory usage. A 1024 by 1024 PNG uses 4 megabytes (assuming you are using 32 bit PNGs 1024 x 1024 x 32 in bits) regardless of the size of the compressed file.

Thank you badawe for your "stupid question". I got the same. :)
How can I check this?

And how can the Texture Memory Usage be over 24 MB? My pngs are all about 40kb.

And I'm still having the question if this is the correct way to add a new Manager for each Animation.

Thank you

@Steve sorry about this stupid question, but how i check my texture memory usage? Have some instrument? or printing something in the screen?

Check your texture memory usage. My guess is the fourth animation pushes you over 24Mb.

Hi everyone,

I'm searching for some hours now, reading every thread here, but still finding no solution for my Problem. So I hope you guys can help me killing this bug. :)

I've a character with many different Animations. He walks, he jumps, he idles and so on...
For every animation I got a png file with the Sprite-Atlas and a .plist file with the coordinates of the single images.

Now I wrote a function which generates, for each Sprite-Atlas, a new Manager, a new Sprite and a new SpriteAnimation and stores them in a dictionary, which is the return value of this function.

The function is located in my Singelton Manager Class, so I can call it from all my other Classes to generate a new Animation. So the character, the enemies, the world are calling this function.

The returned dictionary will be added to a Dictionary-Property in these objects and the manager will be added as a child to the layer.

Now everytime I need a specific animation I make the Sprite visible and start its Animation.

Three Animations worked fine in one class but the fourth one kills the app. It starts to stutter very hardly. CPU Usage seems to be 100% but only on the devices, NOT in the simulator.

What can be the problem?
Do I realy need a new Manager for every .png Sprite-Atlas?

Thank you very much,

here is an example call:

[self.animationDict addEntriesFromDictionary:[[Manager defaultManager] generateNewAnimaton:@"walk" capacity:32 image:@"walk.png" delay:0.04f width:71 height:64 seq:@"walk.plist"]];

[self addChild:[animationDict valueForKey:@"walkManager"] z:1];

here's the function:

- (NSMutableDictionary*) generateNewAnimaton: (NSString*)name capacity:(int)capacity image:(NSString*)image delay:(float)delay width:(int)width height:(int)height seq:(NSString*)sequence
{
	animationDict = [NSMutableDictionary dictionary];

	AtlasSpriteManager* manager = [AtlasSpriteManager spriteManagerWithFile:image capacity:capacity];
	AtlasAnimation* animation   = [AtlasAnimation animationWithName:name delay:delay];

	NSDictionary* d = [NSDictionary dictionaryWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:sequence]];

	NSArray* kList = [[d allKeys] sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)]; 

	for( NSString* key in kList )
	{
		NSDictionary* myDict = [d objectForKey:key];

		NSInteger x = [[myDict valueForKey:@"x"] integerValue];
		NSInteger y = [[myDict valueForKey:@"y"] integerValue];
		NSInteger w = [[myDict valueForKey:@"w"] integerValue];
		NSInteger h = [[myDict valueForKey:@"h"] integerValue];

		[animation addFrameWithRect: CGRectMake( x, y, w, h ) ];
	}

	AtlasSprite* sprite;

	sprite = [AtlasSprite spriteWithRect:CGRectMake( 1, 1, width, height ) spriteManager: manager];

	sprite.visible = false;
	sprite.transformAnchor = CGPointMake( 0, 0 );

	[manager addChild:sprite];

	[animationDict setValue:manager   forKey:[name stringByAppendingString:@"Manager"]];
	[animationDict setValue:animation forKey:[name stringByAppendingString:@"Animation"]];
	[animationDict setValue:sprite    forKey:[name stringByAppendingString:@"Sprite"]];

	return animationDict;
}
