Question

我在cocos2d动画中遇到问题，第一次运行动画时效果很好，经过一段时间后，动画速度变慢了

我使用了以下代码

-(void)animateImages:(NSString *)animationName startImageName:(NSString*)sImage  individualImageName:(NSString *)imgName withDelay:(CGFloat)delay startFrame:(NSInteger)sFrame endFrame:(NSInteger)eFrame {

isAnimating=YES;


[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:[NSString stringWithFormat:@"%@.plist",animationName]];        

// Create a sprite sheet with the March images
CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:[NSString stringWithFormat:@"%@.png",animationName]];



[self addChild:spriteSheet z:0];

// Load up the frames of our animation
NSMutableArray *walkAnimFrames = [NSMutableArray array];
for(int i = sFrame; i <= eFrame; i=i+2) {
    [walkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"%@ %d.jpg",imgName,i]]];//@"stand march %d.jpg"
}


NSLog(@"After NSMutableArray");


    CCAnimation *walkAnim = [CCAnimation animationWithFrames:walkAnimFrames delay:delay];
//    CCAction *standByAtion =[CCSequence actions:                          
//                             [CCRepeat actionWithAction:[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:YES] times:1],[CCCallFunc actionWithTarget:self selector:@selector(callAgain:)],nil];

CCAction *standByAtion =[CCSequence actions:                          
                         [CCRepeat actionWithAction:[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO] times:1],[CCCallFunc actionWithTarget:self selector:@selector(setAnimatingToFalseAfterAnimation:)],nil];


 [walkAnimFrames removeAllObjects];
 walkAnimFrames=nil;

CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite *images = [CCSprite spriteWithSpriteFrameName:[NSString stringWithFormat:@"%@",sImage]];//@"stand march 101.jpg"

images.position=ccp(winSize.width/2,winSize.height/2);
images.scaleX=1.6;
images.scaleY=1.59;




[spriteSheet addChild:images];

[images runAction:standByAtion];

if (!isInInitMethod && isTalking==NO) {
    NSString *audioName=[NSString stringWithFormat:@"Jump.caf"];
    [self playSoundEffectNamed:audioName];
}
}

如果runloop没有运行完整周期，则自动释放的对象不会被释放。使用仪器并跟踪您的分配。
