CCAnimation and CCAnimate leak? - cocos2d-iphone

Question

In my #Monster class, there are 3 different walk animation.
"Monster.h"
#interface Monster : CCSprite{
CCAction *fWalk;
CCAction *bWalk;
CCAction *hWalk;
}
#property (nonatomic, retain) CCAction *fWalk;
#property (nonatomic, retain) CCAction *bWalk;
#property (nonatomic, retain) CCAction *hWalk;
"Monster.m"
+ (id) monsterInit...
{
Monster *sprite = ...// initialization
NSMutableArray *frameArray = [NSMutableArray array];
for ( int i = 0; i < 3; i++ ) {
NSString *fileName = [NSString stringWithFormation:#"%d.png", i];
[frameArray addObject[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:fileName]];
}
CCAnimation *walk = [CCAnimation animationWithFrames:frameArray delay:0.1f];
self.fWalk = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walk restoreOriginalFrame:NO]];
[frameArray removeAllObjects];
for ( int i = 3; i < 6; i++ ) {
NSString *fileName = [NSString stringWithFormation:#"%d.png", i];
[frameArray addObject[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:fileName]];
}
walk = [CCAnimation animationWithFrames:frameArray delay:0.1f];
sprite.bWalk = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walk restoreOriginalFrame:NO]];
[frameArray removeAllObjects];
for ( int i = 6; i < 9; i++ ) {
NSString *fileName = [NSString stringWithFormation:#"%d.png", i];
[frameArray addObject[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:fileName]];
}
walk = [CCAnimation animationWithFrames:frameArray delay:0.1f];
sprite.hWalk = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walk restoreOriginalFrame:NO]];
return sprite;
}
- (void) dealloc
{
[fWalk release];
[bWalk release];
[hWalk release];
[super dealloc];
}
When I run this app with performance tool - Leaks. Instruments display statement which is "CCAnimation *walk...", "self.fWalk...", "walk = ...", "self.bWalk...", "walk = ...", "self.hWalk.." induce memory leaks.
I checked source code about CCAnimation and CCAnimate, they are all "autorelease".I don't know why this leaks happened.
Any idea on what to do?

Answer 1

You have to retain the actions if you plan to use them later, because they are autoreleased when created with the actionWithAction method. Like this:
self.fWalk = [[CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walk restoreOriginalFrame:NO]] retain];
Otherwise, your monster class doesn't own the actions and they are autoreleased when you leave the init method.

Ok but when you save all animations into an Array like this:
CCAnimation *anim = [CCAnimation animationWithSpriteFrames:animFrames delay:pDelay];
CCAnimate *animate = [CCAnimate actionWithAnimation:anim];
CCCallFunc *callback = [CCCallFunc actionWithTarget:pTarget selector:pCallBack];
CCSequence *seq = [CCSequence actions:animate, callback , nil];
NSMutableDictionary *animations;
[animations setValue:seq forKey:pName];
- (void)dealloc {
for (NSString* key in [animations allKeys]) {
CCAction *action = [animations objectForKey:key];
[self stopAction:action];
[action stop];
}
[animations removeAllObjects];
//[[CCSpriteFrameCache sharedSpriteFrameCache] removeUnusedSpriteFrames];
}
The CCAnimation is not release...
