Could you just not add a parameter to the singleton function that references a texture2d?

For example:

//Declare a texture 2d / CCSpriteSheet
CCSpriteSheet * sheet = [CCSpriteSheet spriteSheetWithFile:@"file.png"];

//Pass the texture of the spritesheet to your singleton function
CustomAnimateObject * anim1 = [singleton createAnimation:sheet.texture];

//The CustomAnimateObject would have the following properties
CCAnimation * animation;
CCAction * animationAction;

//Would have the following init function:
-(id) initWithAnimation:(CCAnimation *) animation1 action:(CCAction *) animationAction1;

//Singleton function would then do the following instead:
CCAnimation * anim1;
CCAction *action1;

anim1 = [CCAnimation animationWithName:@"whatever" delay:0.1f];
for(int i=0;i<9;i++)
{
  [anim1 addFrameWithTexture:animationTexture rect: CGRectMake(i*64, 0,64, 128)];
}
action1 =[Animate actionWithAnimation:anim1 restoreOriginalFrame:NO];
//Depending on if the CustomAnimationObject is just NSObject or uses a CCNode the allocing will be different or the same
CustomAnimationObject *CAO = [[CustomAnimationObject node] initWithAnimation:anim1 action: action1];

//Then in your CustomAnimationObject you would then retain the 2 objects passed to it in the init function
//Finally we return the new CustomAnimationObject
return CAO;

Please note all is pseudo code and may need adjusting according to your needs.

no one knows any way?

please i really need it

Im trying to migrate from 0.8.2 to 0.99, i think all its done but the CCAnimation migration.

I have a singleton class that keeps some CCAnimations that can be shared with diferents CCSpriteSheets, for example, i have 3 CCSpriteSheets, with diferent textures but same number of frames, and same size, i usually create a CCAction with the animation of that CCSprites, something like this:

[code]
static CCAnimation *aniZ1Morir;
static CCAction *accZ1Morir;

aniZ1Morir = [[CCAnimation animationWithName:@"aniZ1Morir" delay:0.1f] retain];
for(int i=0;i<9;i++) {
[aniZ1Morir addFrameWithRect: CGRectMake(i*64, 0, 64, 128) ];
}
accZ1Morir = [[Animate actionWithAnimation:aniZ1Morir restoreOriginalFrame:NO] retain];
[/code]

Then when any of the CCSprites that use any of the 3 CCSpriteSheets, need to use the animate, i just run a copy of that "accZ1Morir" CCAction, and of course its compatible.

But now, with the new CCAnimation, i must pass a Texture2D when creating the frames, theres any way to dont need that texture? so i can continue use that singleton class?

This its only an example, but i have more than 50 similar actions, used with arround 100 diferent animations, so migrating can be a really time consuming task if i need to change them all
