Hi,
I have large number of animations in my game. The animation frames are also more than 100 for each animation.
On the screen at a time 10-15 animations are running.
My application became too slower due to the animations. Can someone suggest me the proper way to manage the animations without memory leaks. How should I improve the performance of my game?
What version of cocos2d are you using?
How are you loading and running the animations?
Are you using sprite sheets?
How large (dimensions) are the animation frames?
Are you testing on a device or the simulator?
Answers to those might help pin point possible ways to optimise it.
Off the top of my head, if your frames are too large, or your not using spritesheets, they may be your biggest bottleneck.

Hi PhilM,
Here is the code,
CCAnimation *_goodShipSelectionAniamtion = [CCAnimation animationWithName:@"goodShipSelection" delay:0.1f];
for (int i = 1; i<77; i++) {
[_goodShipSelectionAniamtion addFrameWithFilename:[NSString stringWithFormat:@"SelectGoodLeft %02d.png",i]];
}
id action1 = [CCAnimate actionWithAnimation: _goodShipSelectionAniamtion];
[_goodShipSprite runAction: action1];
I am doing animation on CCSprite.
The dimensions of images are 320X480.
Testing on the simulator.
I am using cocos2d-iphone-0.99.0-final.
A couple of things jump out (as suggested both by PhilM and SwizzerSweet):
1) Large sprites are slow. Period. Even if you follow every rule in the book, if your sprite frames cover the entire screen, iPod performance will suffer. See if you can break your animation down to smaller chunks - are you really animating your entire screen or just an eye blink of some creature in the corner?
2) Because you are using addFrameWithFilename, you are creating a brand new texture for each animation frame. 77 textures at 480x320 are bound to be slow. You should look into CCSpriteSheet to see how you can cram several, preferably all, of your frames into a single texture. On the iPhone, I believe the max texture size is 1024x1024. 77 frames as 480x320 each are clearly not going to fit. However, if you optimize your animations and break them down into smaller, reusable chunks, you may just get lucky.
There's NO WAY you can load 77 480x320 (which will get padded out to 512x512) textures into openGL on the iPhone at the same time because you have to work under a 24MB limit.
It looks like you are trying to do full screen video. Have you tried making a video file instead of separate frames?
Also I did some searching on how to playback video manually and apply it's data to an opengl texture in real time on the iphone but came up empty. So if you do find something like this post it back here :)
